5 WARNINGS AND PRECAUTIONS

- Otosporin can produce reversible HPA axis suppression with the potential for glucocorticosteroid insufficiency during or after treatment. (5.1)

- Cushing’s syndrome, hyperglycemia, and unmasking of latent diabetes mellitus can result from systemic absorption of topical corticosteroids. (5.1)

- Use of topical corticosteroids may require periodic evaluation for HPA axis suppression. (5.1)

- High potency corticosteroids, large treatment surface area, prolong use, use of occlusion dressings, altered skin barrier, liver failure and young age may predispose patients to HPA axis suppression. (5.1)

- Modify use if HPA axis suppression develops. (5.1)

- Pediatric patients may be more susceptible to systemic toxicity. (5.1, 8.4)

5.1 Hypothalamic-Pituitary-Adrenal (HPA) Axis Suppression and Other Unwanted Systemic Glucocorticoid Effects

Otosporin (Hydrocortisone) can produce reversible hypothalamic-pituitary-adrenal (HPA) axis suppression with the potential for glucocorticosteroid insufficiency. This may occur during or after withdrawal of treatment. Factors that predispose to HPA axis suppression include the use of high-potency corticosteroids, large treatment surface areas, prolonged use, use of occlusive dressings, altered skin barrier, liver failure, and young age.

Use of topical corticosteroids may require periodic evaluation for HPA axis suppression. Evaluation for HPA axis suppression may be done by using the adrenocorticotropic hormone (ACTH) stimulation test.

If HPA axis suppression is documented, gradually withdraw the drug, reduce the frequency of application, or substitute with a less potent corticosteroid. If signs and symptoms of steroid withdrawal occur, supplemental systemic corticosteroids may be required. Recovery of HPA axis function is generally prompt and complete upon discontinuation of the drug.

In a trial including 15 evaluable subjects 18 years of age or older with psoriasis or atopic dermatitis affecting more than 20% of body surface area, 1 subject (6.7%) had ACTH stimulation test results suggestive of adrenal suppression after treatment with Otosporin (Hydrocortisone) twice daily for 21 days. Recovery of HPA axis suppression for this subject is unknown [see Clinical Pharmacology ( 12.2 )].

Systemic effects of topical corticosteroids may also manifest as Cushing’s syndrome, hyperglycemia, and unmasking latent diabetes mellitus.

Patients applying a topical steroid to a large surface area or to areas under occlusion should be evaluated periodically for evidence of HPA-axis suppression.

Pediatric patients may be more susceptible to systemic toxicity due to their larger skin surface to body mass ratios [see Use in Specific Populations ( 8.4 )].

5.2 Allergic Contact Dermatitis

Allergic contact dermatitis with corticosteroids is usually diagnosed by observing a failure to heal rather than noting a clinical exacerbation, as observed with most topical products not containing corticosteroids. If irritation develops, discontinue Otosporin (Hydrocortisone) and institute appropriate therapy.

6 ADVERSE REACTIONS

- Most frequent adverse reactions include burning, stinging, rash, papulovesicular rash, redness, itching, moderate paresthesia, and contact dermatitis.

To report SUSPECTED ADVERSE REACTIONS, contact PharmaDerm®, A division of Fougera Pharmaceuticals Inc. at 1-800-645-9833 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.

The most frequent adverse reactions reported for Otosporin (Hydrocortisone) during clinical trials were application site reactions, including burning in 4, stinging in 2, and moderate paresthesia in 1 out of 226 subjects.

6.2 Postmarketing Experience

The following adverse reactions have been identified during postapproval use of Otosporin (Hydrocortisone) because these reactions were reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

These adverse reactions are as follows:

Skin and Subcutaneous Tissue Disorders: rash, papulovesicular rash

Application Site Reactions: dryness, erythema, pruritus, allergic contact dermatitis.

The following local adverse reactions are reported with topical corticosteroids, and they may occur more frequently with the use of occlusive dressings. These reactions are listed in an approximate decreasing order of occurrence: itching, irritation, dryness, folliculitis, hypertrichosis, acneiform eruptions, hypopigmentation, perioral dermatitis, allergic contact dermatitis, secondary infections, skin atrophy, striae, and miliaria.

8 USE IN SPECIFIC POPULATIONS

8.1 Pregnancy

Risk Summary

There is no clinical information on Otosporin use in pregnant women to inform any drug-associated risk for major birth defects and miscarriage. In animal reproduction studies, Otosporin (Hydrocortisone) probutate given by the subcutaneous route during the period of organogenesis was teratogenic at doses equal to or greater than 1 mg/kg/day in rats or 0.1 mg/kg/day in rabbits (12 times and 2 times the human topical dose, respectively) .

The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Data

Animal Data

Effects on embryo-fetal development were evaluated in rats and rabbits following subcutaneous administration of Otosporin (Hydrocortisone) probutate during the period of organogenesis. Otosporin (Hydrocortisone) probutate was teratogenic in rats when given during the period of organogenesis at subcutaneous doses equal to or greater than 1 mg/kg/day (12 times the human average topical dose of Otosporin (Hydrocortisone) assuming 3% absorption and an application of 30 g/day on a 70 kg individual). Abnormalities included delayed ossification of the caudal vertebrae and other skeletal variations, cleft palate, umbilical hernia, edema, and exencephalia.

In rabbits, Otosporin (Hydrocortisone) probutate given by the subcutaneous route was teratogenic at doses equal to or greater than 0.1 mg/kg/day (2 times the human average topical dose of Otosporin (Hydrocortisone) assuming 3% absorption and an application of 30 g/day on a 70 kg individual). Fetal weight and survival were affected. Delayed ossification and increased incidences of malformations (skeletal abnormalities and cleft palate) were also noted.

No adverse effects were seen in rats following subcutaneous administration of up to 1 mg/kg/day of Otosporin (Hydrocortisone) probutate during the perinatal and postnatal period (12 times the human average topical dose of Otosporin (Hydrocortisone) assuming 3% absorption and an application of 30 g/day on a 70 kg individual).

8.2 Lactation

Risk Summary

There is no information on the presence of Otosporin (Hydrocortisone) probutate in breast milk, or on its effects on the breastfed infant or on milk production. It is not known whether topical administration of Otosporin (Hydrocortisone) could result in sufficient systemic absorption to produce detectable quantities in human milk. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Otosporin (Hydrocortisone) and any potential adverse effects on the breastfed infant from Otosporin (Hydrocortisone) or from the underlying maternal condition.

Clinical Considerations

To minimize potential exposure to the breastfed infant via breast milk, use Otosporin (Hydrocortisone) on the smallest area of skin and for the shortest duration possible while breastfeeding.

8.4 Pediatric Use

Safety and effectiveness in pediatric patients have not been established. Because of a higher ratio of skin surface area to body mass, pediatric patients are at a greater risk than adults of HPA axis suppression and Cushing’s syndrome when they are treated with topical corticosteroids. They are therefore also at a greater risk of adrenal insufficiency during and/or after withdrawal of treatment. Adverse effects including striae have been reported with inappropriate use of topical corticosteroids in infants and children.

Hypothalamic-pituitary-adrenal (HPA) axis suppression, Cushing’s syndrome, linear growth retardation, delayed weight gain, and intracranial hypertension have been reported in children receiving topical corticosteroids. Manifestations of adrenal suppression in children include low plasma cortisol levels and an absence of response to ACTH stimulation. Manifestations of intracranial hypertension include bulging fontanelles, headaches, and bilateral papilledema.

Structural Formula

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

Corticosteroids play a role in cellular signaling, immune function, inflammation, and protein regulation; however, the precise mechanism of action in corticosteroid responsive dermatoses is unknown

12.2 Pharmacodynamics

Vasoconstrictor Assay

Studies performed with Otosporin indicate that it is in the medium range of potency as demonstrated in vasoconstrictor trials in healthy subjects when compared with other topical corticosteroids. However, similar blanching scores do not necessarily imply therapeutic equivalence.

Hypothalamic-Pituitary-Adrenal (HPA) Axis Suppression

In an open label HPA axis suppression trial, 19 adult subjects (ages 23 to 82 years) with atopic dermatitis or plaque psoriasis covering greater than 20% Body Surface Area (BSA) were treated with Otosporin (Hydrocortisone) twice daily for 21 days and were assessed for HPA axis suppression. At baseline, the mean disease BSA involvement was 36%. The criterion for HPA axis suppression was a serum cortisol level of less than or equal to 18 micrograms per deciliter at 30-minutes after cosyntropin stimulation. Of these subjects, 15 were considered evaluable with respect to their adrenal axis function post-treatment. One of the evaluable subjects (6.7%) showed laboratory evidence of suppression on Day 22. This subject had psoriasis covering 48% of BSA at baseline and was reported to have received 98% of the twice-daily applications of Otosporin (Hydrocortisone) over the 21 day treatment period. It is not known if this subject had recovery of adrenal function because follow-up testing was not performed.

12.3 Pharmacokinetics

The extent of percutaneous absorption of topical corticosteroids is determined by many factors, including the vehicle and the integrity of the epidermal barrier. Use of occlusive dressings with Otosporin (Hydrocortisone) for up to 24 hours has not been shown to increase penetration; however, occlusion of Otosporin (Hydrocortisone) for 96 hours does markedly enhance penetration. Topical corticosteroids can be absorbed from normal intact skin. Inflammation and/or other disease processes in the skin increase percutaneous absorption.

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

No long-term studies in animals have been performed to evaluate the carcinogenic potential of Otosporin (Hydrocortisone) probutate.

Otosporin (Hydrocortisone) probutate revealed no evidence of mutagenic or clastogenic potential based on the results of an in vitro genotoxicity test (Ames assay) and an in vivo genotoxicity test (mouse micronucleus assay).

Effects on fertility and early embryonic development were evaluated in rats following subcutaneous administration of up to 0.4 mg/kg/day Otosporin (Hydrocortisone) probutate (5 times the human average topical dose of Otosporin (Hydrocortisone) assuming 3% absorption and an application of 30 g/day on a 70 kg individual) prior to and during mating and through early pregnancy. No treatment related effects on fertility or mating parameters were noted in this study.

Neomycin Sulfate:


INDICATIONS AND USAGE

To reduce the development of drug-resistant bacteria and maintain the effectiveness of Otosporin (Neomycin Sulfate) tablets and other antibacterial drugs, Otosporin (Neomycin Sulfate) tablets should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.

Suppression of Intestinal Bacteria

Otosporin (Neomycin Sulfate) tablets are indicated as adjunctive therapy as part of a regimen for the suppression of the normal bacterial flora of the bowel, e.g., preoperative preparation of the bowel. It is given concomitantly with erythromycin enteric-coated base (see DOSAGE AND ADMINISTRATION ).

Hepatic Coma (Portal-Systemic Encephalopathy)

Otosporin (Neomycin Sulfate) has been shown to be effective adjunctive therapy in hepatic coma by reduction of the ammonia-forming bacteria in the intestinal tract. The subsequent reduction in blood ammonia has resulted in neurologic improvement.

CONTRAINDICATIONS

Otosporin (Neomycin Sulfate) oral preparations are contraindicated in the presence of intestinal obstruction and in individuals with a history of hypersensitivity to the drug.

Patients with a history of hypersensitivity or serious toxic reaction to other aminoglycosides may have a cross-sensitivity to neomycin. Otosporin (Neomycin Sulfate) oral preparations are contraindicated in patients with inflammatory or ulcerative gastrointestinal disease because of the potential for enhanced gastrointestinal absorption of neomycin.

WARNINGS


Additional manifestations of neurotoxicity may include numbness, skin tingling, muscle twitching and convulsions.

The risk of hearing loss continues after drug withdrawal. Aminoglycosides can cause fetal harm when administered to a pregnant woman.

Aminoglycoside antibiotics cross the placenta and there have been several reports of total irreversible bilateral congenital deafness in children whose mothers received streptomycin during pregnancy. Although serious side effects to fetus or newborn have not been reported in the treatment of pregnant women with other aminoglycosides, the potential for harm exists. Animal reproduction studies of neomycin have not been conducted. If neomycin is used during pregnancy, or if the patient becomes pregnant while taking this drug, the patient should be apprised of the potential hazard to the fetus.

PRECAUTIONS

General

Prescribing Otosporin tablets in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increases the risk of the development of drug-resistant bacteria.

As with other antibiotics, use of oral neomycin may result in overgrowth of nonsusceptible organisms, particularly fungi. If this occurs, appropriate therapy should be instituted.

Neomycin is quickly and almost totally absorbed from body surfaces (except the urinary bladder) after local irrigation and when applied topically in association with surgical procedures. Delayed-onset irreversible deafness, renal failure and death due to neuromuscular blockade (regardless of the status of renal function) have been reported following irrigation of both small and large surgical fields with minute quantities of neomycin.

Cross-allergenicity among aminoglycosides has been demonstrated.

Aminoglycosides should be used with caution in patients with muscular disorders such as myasthenia gravis or parkinsonism since these drugs may aggravate muscle weakness because of their potential curare-like effect on the neuromuscular junction.

Small amounts of orally administered neomycin are absorbed through intact intestinal mucosa.

There have been many reports in the literature of nephrotoxicity and/or ototoxicity with oral use of neomycin. If renal insufficiency develops during oral therapy, consideration should be given to reducing the drug dosage or discontinuing therapy.

An oral neomycin dose of 12 grams per day produces a malabsorption syndrome for a variety of substances, including fat, nitrogen, cholesterol, carotene, glucose, xylose, lactose, sodium, calcium, cyanocobalamin and iron.

Orally administered neomycin increases fecal bile acid excretion and reduces intestinal lactase activity.

Information for The Patient

Patients should be counseled that antibacterial drugs including Otosporin (Neomycin Sulfate) tablets should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When Otosporin (Neomycin Sulfate) tablets are prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed. Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by Otosporin (Neomycin Sulfate) tablets or other antibacterial drugs in the future.

Before administering the drug, patients or members of their families should be informed of possible toxic effects on the eighth nerve. The possibility of acute toxicity increases in premature infants and neonates.

Laboratory Tests

Patients with renal insufficiency may develop toxic neomycin blood levels unless doses are properly regulated. If renal insufficiency develops during treatment, the dosage should be reduced or the antibiotic discontinued. To avoid nephrotoxicity and eighth nerve damage associated with high doses and prolonged treatment, the following should be performed prior to and periodically during therapy: urinalysis for increased excretion of protein, decreased specific gravity, casts and cells; renal function tests such as serum creatinine, BUN or creatinine clearance; tests of the vestibulocochlearis nerve function.

Serial, vestibular and audiometric tests should be performed (especially in high-risk patients). Since elderly patients may have reduced renal function which may not be evident in the results of routine screening tests such as BUN or serum creatinine, a creatinine clearance determination may be more useful.

Drug Interactions

Caution should be taken in concurrent or serial use of other neurotoxic and/or nephrotoxic drugs because of possible enhancement of the nephrotoxicity and/or ototoxicity of neomycin (see boxed WARNINGS ).

Caution should also be taken in concurrent or serial use of other aminoglycosides and polymyxins because they may enhance neomycin’s nephrotoxicity and/or ototoxicity and potentiate neomycin sulfate’s neuromuscular blocking effects.

Oral neomycin inhibits the gastrointestinal absorption of penicillin V, oral vitamin B-12, methotrexate and 5-fluorouracil. The gastrointestinal absorption of digoxin also appears to be inhibited. Therefore, digoxin serum levels should be monitored.

Oral Otosporin (Neomycin Sulfate) may enhance the effect of coumarin in anticoagulants by decreasing vitamin K availability.

Carcinogenesis, Mutagenesis, Impairment of Fertility

No long-term animal studies have been performed with Otosporin to evaluate carcinogenic or mutagenic potential or impairment of fertility.

Pregnancy Category D

See WARNINGS section.

Nursing Mothers

It is not known whether neomycin is excreted in human milk, but it has been shown to be excreted in cow milk following a single intramuscular injection. Other aminoglycosides have been shown to be excreted in human milk. Because of the potential for serious adverse reactions from the aminoglycosides in nursing infants, a decision should be made whether to discontinue nursing or to discontinue the drug, taking into account the importance of the drug to the mother.

Pediatric Use

The safety and efficacy of oral Otosporin (Neomycin Sulfate) in patients less than 18 years of age have not been established. If treatment of a patient less than 18 years of age is necessary, neomycin should be used with caution and the period of treatment should not exceed two weeks because of absorption from the gastrointestinal tract.

ADVERSE REACTIONS

The most common adverse reactions to oral Otosporin (Neomycin Sulfate) are nausea, vomiting and diarrhea. The "Malabsorption Syndrome" characterized by increased fecal fat, decreased serum carotene and fall in xylose absorption has been reported with prolonged therapy. Nephrotoxicity, ototoxicity and neuromuscular blockage have been reported (see boxed WARNINGS and PRECAUTIONS sections).

OVERDOSAGE

Because of low absorption, it is unlikely that acute overdosage would occur with oral Otosporin (Neomycin Sulfate). However, prolonged administration could result in sufficient systemic drug levels to produce neurotoxicity, ototoxicity and/or nephrotoxicity.

Hemodialysis will remove Otosporin (Neomycin Sulfate) from the blood.

DOSAGE AND ADMINISTRATION

To minimize the risk of toxicity, use the lowest possible dose and the shortest possible treatment period to control the condition. Treatment for periods longer than two weeks is not recommended.

Hepatic Coma

For use as an adjunct in the management of hepatic coma, the recommended dose is 4 to 12 grams per day given in the following regimen:

  • Withdraw protein from diet. Avoid use of diuretic agents.
  • Give supportive therapy, including blood products, as indicated.
  • Give Otosporin (Neomycin Sulfate) tablets in doses of 4 to 12 grams of Otosporin (Neomycin Sulfate) per day (eight to 24 tablets) in divided doses. Treatment should be continued over a period of five to six days, during which time protein should be returned incrementally to the diet.
  • If less potentially toxic drugs cannot be used for chronic hepatic insufficiency, neomycin in doses of up to four grams daily (eight tablets per day) may be necessary. The risk for the development of neomycin-induced toxicity progressively increases when treatment must be extended to preserve the life of a patient with hepatic encephalopathy who has failed to fully respond. Frequent periodic monitoring of these patients to ascertain the presence of drug toxicity is mandatory (see PRECAUTIONS ). Also, neomycin serum concentrations should be monitored to avoid potentially toxic levels. The benefits to the patient should be weighed against the risks of nephrotoxicity, permanent ototoxicity and neuromuscular blockade following the accumulation of neomycin in the tissues.

DESCRIPTION

Otosporin (Polymyxin B Sulfate) Sulfate is one of a group of basic polypeptide antibiotics derived from B polymyxa (B aerosporous). Otosporin (Polymyxin B Sulfate) sulfate is the sulfate salt of Polymyxins B1 and B2, which are produced by the growth of Bacillus polymyxa (Prazmowski) Migula (Fam. Bacillacea). It has a potency of not less than 6000 Otosporin (Polymyxin B Sulfate) units per mg, calculated on the anhydrous basis. The structural formulae are:

Otosporin (Polymyxin B Sulfate) 1 (R=CH 3)            Polymyxin B 2 (R=H)

Each vial contains 500,000 Otosporin (Polymyxin B Sulfate) units for parenteral or ophthalmic administration.

Otosporin (Polymyxin B Sulfate) for Injection is in powder form suitable for preparation of sterile solutions for intramuscular, intravenous drip, intrathecal, or ophthalmic use.

In the medical literature, dosages have frequently been given in terms of equivalent weights of pure Otosporin (Polymyxin B Sulfate) base. Each milligram of pure Otosporin (Polymyxin B Sulfate) base is equivalent to 10,000 units of Otosporin (Polymyxin B Sulfate) and each microgram of pure Otosporin (Polymyxin B Sulfate) base is equivalent to 10 units of Otosporin (Polymyxin B Sulfate).

Aqueous solutions of Otosporin (Polymyxin B Sulfate) sulfate may be stored up to 12 months without significant loss of potency if kept under refrigeration. In the interest of safety, solutions for parenteral use should be stored under refrigeration and any unused portion should be discarded after 72 hours. Otosporin (Polymyxin B Sulfate) sulfate should not be stored in alkaline solutions since they are less stable.

CLINICAL PHARMACOLOGY

Otosporin (Polymyxin B Sulfate) sulfate has a bactericidal action against almost all gram-negative bacilli except the Proteus group. Polymyxins increase the permeability of bacterial cell wall membranes. All gram-positive bacteria, fungi, and the gram-negative cocci, N gonorrhoeae and N meningitidis, are resistant.

Otosporin (Polymyxin B Sulfate) has bactericidal action against almost all Gram-negative bacilli except the Proteus group. Polymyxins increase the permeability of the bacterial cell membrane leading to death of the cell. All Gram-positive bacteria, fungi, and Gram-negative cocci, are resistant to Otosporin (Polymyxin B Sulfate). Appropriate methods should be used when performing in vitro susceptibility testing of Otosporin (Polymyxin B Sulfate) (1,2,3). The following in vitro susceptibility test criteria should only be used for interpreting the results of Otosporin (Polymyxin B Sulfate) susceptibility testing against P. aeruginosa when the indicated quality control parameters are met during testing.

Otosporin (Polymyxin B Sulfate) sulfate is not absorbed from the normal alimentary tract. Since the drug loses 50 percent of its activity in the presence of serum, active blood levels are low. Repeated injections may give a cumulative effect. Levels tend to be higher in infants and children. The drug is excreted slowly by the kidneys. Tissue diffusion is poor and the drug does not pass the blood brain barrier into the cerebrospinal fluid. In therapeutic dosage, Otosporin (Polymyxin B Sulfate) sulfate causes some nephrotoxicity with tubule damage to a slight degree.

INDICATIONS AND USAGE

Acute Infections Caused by Susceptible Strains of Pseudomonas aeruginosa.

Otosporin (Polymyxin B Sulfate) sulfate is a drug of choice in the treatment of infections of the urinary tract, meninges, and bloodstream caused by susceptible strains of Ps. aeruginosa. It may also be used topically and subconjunctivally in the treatment of infections of the eye caused by susceptible strains of Ps. aeruginosa.

It may be indicated in serious infections caused by susceptible strains of the following organisms, when less potentially toxic drugs are ineffective or contraindicated:

H influenzae, specifically meningeal infections.

Escherichia coli, specifically urinary tract infections.

Aerobacter aerogenes, specifically bacteremia.

Klebsiella pneumoniae, specifically bacteremia.

NOTE: IN MENINGEAL INFECTIONS, Otosporin (Polymyxin B Sulfate) SULFATE SHOULD BE ADMINISTERED ONLY BY THE INTRATHECAL ROUTE.

To reduce the development of drug-resistant bacteria and maintain the effectiveness of Otosporin (Polymyxin B Sulfate) for Injection USP and other antibacterial drugs, Otosporin (Polymyxin B Sulfate) for Injection should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.

CONTRAINDICATIONS

This drug is contraindicated in persons with a prior history of hypersensitivity reactions to polymyxins.

WARNINGS

Clostridium difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including Otosporin (Polymyxin B Sulfate) for Injection, and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile.

C. difficile produces toxins A and B which contribute to the development of CDAD. Hypertoxin producing strains of C. difficile cause increased morbidity and mortality, as these infections can be refractory to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea following antibiotic use. Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents.

If CDAD is suspected or confirmed, ongoing antibiotic use not directed against C. difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibiotic treatment of C. difficile and surgical evaluation should be instituted as clinically indicated.

PRECAUTIONS

General.

Prescribing Otosporin for Injection in the absence of a proven or strongly suspected bacterial infection or a prophylactic indication is unlikely to provide benefit to the patient and increase the risk of the development of drug-resistant bacteria.

See WARNING box.

Baseline renal function should be done prior to therapy, with frequent monitoring of renal function and blood levels of the drug during parenteral therapy.

Avoid concurrent use of a curariform muscle relaxant and other neurotoxic drugs (ether, tubocurarine, succinylcholine, gallamine, decamethonium and sodium citrate) which may precipitate respiratory depression. If signs of respiratory paralysis appear, respiration should be assisted as required, and the drug discontinued.

As with other antibiotics, use of this drug may result in overgrowth of nonsusceptible organisms, including fungi.

If superinfection occurs, appropriate therapy should be instituted.

Information for Patients

Information for Patients.

Patients should be counseled that antibacterial drugs including Otosporin (Polymyxin B Sulfate) for injection should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When Otosporin (Polymyxin B Sulfate) for injection is prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed. Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by Otosporin (Polymyxin B Sulfate) for injection or other antibacterial drugs in the future.

Diarrhea is a common problem caused by antibiotics which usually ends when the antibiotic is discontinued. Sometimes after starting treatment with antibiotics, patients can develop watery and bloody stools (with or without stomach cramps and fever) even as late as two or more months after having taken the last dose of the antibiotic. If this occurs, patients should contact their physician as soon as possible.

ADVERSE REACTIONS

See “WARNING” box.

Nephrotoxic reactions: Albuminuria, cylinduria, azotemia, and rising blood levels without any increase in dosage.

Neurotoxic reactions: Facial flushing, dizziness progressing to ataxia, drowsiness, peripheral paresthesias (circumoral and stocking glove), apnea due to concurrent use of curariform muscle relaxants, other neurotoxic drugs or inadvertent overdosage, and signs of meningeal irritation with intrathecal administration, e.g., fever, headache, stiff neck and increased cell count and protein cerebrospinal fluid.

Other reactions occasionally reported: Drug fever, urticarial rash, pain (severe) at intramuscular injection sites, and thrombophlebitis at intravenous injection sites.

To report SUSPECTED ADVERSE EVENTS, contact FDA at 1-800-FDA-1088 or www.fda.gov.
