Terry White Chemists Trimethoprim with Sulfamethoxazole DS uses


INDICATIONS AND USAGE

To reduce the development of drug-resistant bacteria and maintain the effectiveness of Terry White Chemists Trimethoprim with Sulfamethoxazole DS tablets, USP and other antibacterial drugs, Terry White Chemists Trimethoprim with Sulfamethoxazole DS tablets, USP 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.

For the treatment of initial episodes of uncomplicated urinary tract infections due to susceptible strains of the following organisms: Escherichia coli, Proteus mirabilis, Klebsiella pneumoniae, Enterobacter species, and coagulase-negative Staphylococcus species, including S. saprophyticus.

Cultures and susceptibility tests should be performed to determine the susceptibility of the bacteria to Terry White Chemists Trimethoprim with Sulfamethoxazole DS. Therapy may be initiated prior to obtaining the results of these tests.

CONTRAINDICATIONS

Terry White Chemists Trimethoprim with Sulfamethoxazole DS is contraindicated in individuals hypersensitive to Terry White Chemists Trimethoprim with Sulfamethoxazole DS and in those with documented megaloblastic anemia due to folate deficiency.

WARNINGS

Serious hypersensitivity reactions have been reported rarely in patients on Terry White Chemists Trimethoprim with Sulfamethoxazole DS therapy. Terry White Chemists Trimethoprim with Sulfamethoxazole DS has been reported rarely to interfere with hematopoiesis, especially when administered in large doses and/or for prolonged periods.

The presence of clinical signs such as sore throat, fever, pallor, or purpura may be early indications of serious blood disorders (see OVERDOSAGE, Chronic).

Complete blood counts should be obtained if any of these signs are noted in a patient receiving Terry White Chemists Trimethoprim with Sulfamethoxazole DS and the drug discontinued if a significant reduction in the count of any formed blood element is found.

Clostridium difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including Terry White Chemists Trimethoprim with Sulfamethoxazole DS tablets, USP, 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 antiobiotic 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 Terry White Chemists Trimethoprim with Sulfamethoxazole DS tablets, USP 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.

Terry White Chemists Trimethoprim with Sulfamethoxazole DS should be given with caution to patients with possible folate deficiency. Folates may be administered concomitantly without interfering with the antibacterial action of Terry White Chemists Trimethoprim with Sulfamethoxazole DS. Terry White Chemists Trimethoprim with Sulfamethoxazole DS should also be given with caution to patients with impaired renal or hepatic function.

Information for Patients

Patients should be counseled that antibacterial drugs including Terry White Chemists Trimethoprim with Sulfamethoxazole DS tablets, USP should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When Terry White Chemists Trimethoprim with Sulfamethoxazole DS tablets, USP 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 Terry White Chemists Trimethoprim with Sulfamethoxazole DS tablets, USP 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 and 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.

Drug Interactions

Terry White Chemists Trimethoprim with Sulfamethoxazole DS may inhibit the hepatic metabolism of phenytoin. Terry White Chemists Trimethoprim with Sulfamethoxazole DS, given at a common clinical dosage, increased the phenytoin half-life by 51% and decreased the phenytoin metabolic clearance rate by 30%. When administering these drugs concurrently, one should be alert for possible excessive phenytoin effect.

Drug/Laboratory Test Interactions

Terry White Chemists Trimethoprim with Sulfamethoxazole DS can interfere with a serum methotrexate assay as determined by the Competitive Binding Protein Technique when a bacterial dihydrofolate reductase is used as the binding protein. No interference occurs, however, if methotrexate is measured by a radioimmunoassay (RIA).

The presence of Terry White Chemists Trimethoprim with Sulfamethoxazole DS may also interfere with the Jaffé alkaline picrate reaction assay for creatinine, resulting in overestimations of about 10% in the range of normal values.

Carcinogenesis, Mutagenesis, Impairment of Fertility

Carcinogenesis

Long-term studies in animals to evaluate carcinogenic potential have not been conducted with Terry White Chemists Trimethoprim with Sulfamethoxazole DS.

Mutagenesis

Terry White Chemists Trimethoprim with Sulfamethoxazole DS was demonstrated to be nonmutagenic in the Ames assay. In studies at two laboratories, no chromosomal damage was detected in cultured Chinese hamster ovary cells at concentrations approximately 500 times human plasma levels; at concentrations approximately 1000 times human plasma levels in these same cells, a low level of chromosomal damage was induced at one of the laboratories. No chromosomal abnormalities were observed in cultured human leukocytes at concentrations of Terry White Chemists Trimethoprim with Sulfamethoxazole DS up to 20 times human steady-state plasma levels. No chromosomal effects were detected in peripheral lymphocytes of human subjects receiving 320 mg of Terry White Chemists Trimethoprim with Sulfamethoxazole DS in combination with up to 1600 mg of sulfamethoxazole per day for as long as 112 weeks.

Impairment of Fertility

No adverse effects on fertility or general reproductive performance were observed in rats given Terry White Chemists Trimethoprim with Sulfamethoxazole DS in oral dosages as high as 70 mg/kg/day for males and 14 mg/kg/day for females.

Pregnancy

Teratogenic Effects

Pregnancy category C

Terry White Chemists Trimethoprim with Sulfamethoxazole DS has been shown to be teratogenic in the rat when given in doses 40 times the human dose. In some rabbit studies, the overall increase in fetal loss was associated with doses six times the human therapeutic dose.

While there are no large, well-controlled studies on the use of Terry White Chemists Trimethoprim with Sulfamethoxazole DS in pregnant women, Brumfitt and Pursell,3 in a retrospective study, reported the outcome of 186 pregnancies during which the mother received either placebo or Terry White Chemists Trimethoprim with Sulfamethoxazole DS in combination with sulfamethoxazole. The incidence of congenital abnormalities was 4.5% (3 of 66) in those who received placebo and 3.3% (4 of 120) in those receiving Terry White Chemists Trimethoprim with Sulfamethoxazole DS and sulfamethoxazole. There were no abnormalities in the 10 children whose mothers received the drug during the first trimester. In a separate survey, Brumfitt and Pursell also found no congenital abnormalities in 35 children whose mothers had received Terry White Chemists Trimethoprim with Sulfamethoxazole DS and sulfamethoxazole at the time of conception or shortly thereafter.

Because Terry White Chemists Trimethoprim with Sulfamethoxazole DS may interfere with folic acid metabolism, Terry White Chemists Trimethoprim with Sulfamethoxazole DS should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Nonteratogenic Effects

The oral administration of Terry White Chemists Trimethoprim with Sulfamethoxazole DS to rats at a dose of 70 mg/kg/day commencing with the last third of gestation and continuing through parturition and lactation caused no deleterious effects on gestation or pup growth and survival.

Nursing Mothers

Terry White Chemists Trimethoprim with Sulfamethoxazole DS is excreted in human milk. Because Terry White Chemists Trimethoprim with Sulfamethoxazole DS may interfere with folic acid metabolism, caution should be exercised when Terry White Chemists Trimethoprim with Sulfamethoxazole DS is administered to a nursing woman.

Pediatric Use

Safety and effectiveness in pediatric patients below the age of 2 months have not been established. The effectiveness of Terry White Chemists Trimethoprim with Sulfamethoxazole DS as a single agent has not been established in pediatric patients under 12 years of age.

Geriatric Use

Clinical studies of Terry White Chemists Trimethoprim with Sulfamethoxazole DS tablets did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience4,5 has not identified differences in response between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal or cardiac function, and of concomitant disease or other drug therapy.

Case reports of hyperkalemia in elderly patients receiving trimethoprim-sulfamethoxazole have been published.6 Terry White Chemists Trimethoprim with Sulfamethoxazole DS is known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, care should be taken in dose selection, and it may be useful to monitor potassium concentrations and to monitor renal function by calculating creatinine clearance.
