Warnings and Precautions (5) 4/2013
Concomitant use of benzodiazepines and opioids may result in profound sedation, respiratory depression, coma, and death [see Warnings and Precautions (5.1) , Drug Interactions (7) ].
WARNING: RISKS FROM CONCOMITANT USE WITH OPIOIDS
Concomitant use of benzodiazepines and opioids may result in profound sedation, respiratory depression, coma, and death [ see Warnings and Precautions (5.1) , Drug Interactions (7) ] .
Doral is indicated for the treatment of insomnia characterized by difficulty in falling asleep, frequent nocturnal awakenings, and/or early morning awakenings. The effectiveness of Doral has been established in placebo-controlled clinical studies of 5 nights duration in acute and chronic insomnia. The sustained effectiveness of Doral has been established in chronic insomnia in a sleep lab (polysomnographic) study of 28 nights duration. Because insomnia is often transient and intermittent, the prolonged administration of Doral Tablets is generally not necessary or recommended. Since insomnia may be a symptom of several other disorders, the possibility that the complaint may be related to a condition for which there is a more specific treatment should be considered.
Doral, a gamma-aminobutyric (GABAA) agonist, is indicated for the treatment of insomnia characterized by difficulty falling asleep, frequent nocturnal awakenings, and/or early morning awakenings. (1)
Use the lowest dose effective for the patient, as important adverse effects of Doral are dose related. The recommended initial dose is 7.5 mg. The 7.5 mg dose can be increased to 15 mg if necessary for efficacy. The 7.5 mg dose can be achieved by splitting the 15 mg tablet along the score line.
Use the lowest dose effective for the patient
Elderly and debilitated patients may be more sensitive to benzodiazepines.
Tablets, 15 mg, functionally scored, capsule-shaped, light orange, slightly white speckled tablets, impressed with the product identification number 15 on one side of the tablet, and the product name (DORAL) on the other.
15 mg functionally scored tablet, oral (3)
Doral is contraindicated in patients with known hypersensitivity to Doral or other benzodiazepines. Rare cases of angioedema involving the tongue, glottis or larynx have been reported in patients after taking the first or subsequent doses of Doral. Some patients have had additional symptoms such as dyspnea, throat closing, or nausea and vomiting that suggest anaphylaxis. Patients who develop such reactions should not be rechallenged with Doral.
Contraindicated in patients with established or suspected sleep apnea, or with pulmonary insufficiency.
Concomitant use of benzodiazepines, including Doral, and opioids may result in profound sedation, respiratory depression, coma, and death. Because of these risks, reserve concomitant prescribing of these drugs for use in patients for whom alternative treatment options are inadequate.
Observational studies have demonstrated that concomitant use of opioid analgesics and benzodiazepines increases the risk of drug-related mortality compared to use of opioids alone. If a decision is made to prescribe Doral concomitantly with opioids, prescribe the lowest effective dosages and minimum durations of concomitant use, and follow patients closely for signs and symptoms of respiratory depression and sedation. In patients already receiving an opioid analgesic, prescribe a lower initial dose of Doral than indicated in the absence of an opioid and titrate based on clinical response. If an opioid is initiated in a patient already taking Doral, prescribe a lower initial dose of the opioid and titrate based upon clinical response.
Advise both patients and caregivers about the risks of respiratory depression and sedation when Doral is used with opioids. Advise patients not to drive or operate heavy machinery until the effects of concomitant use with the opioid have been determined..
Doral is a central nervous system depressant and can impair daytime function in some patients even when used as prescribed. Prescribers should monitor for excess depressant effects, but impairment can occur in the absence of subjective symptoms, and may not be reliably detected by ordinary clinical exam (i.e. less than formal psychomotor testing). While pharmacodynamics tolerance or adaptation to some adverse depressant effects of Doral may develop, patients using Doral should be cautioned against driving or engaging in other hazardous activities or activities requiring complete mental alertness.
Additive effects occur with concomitant use of other CNS depressants (e.g., other benzodiazepines, opioids, tricyclic antidepressants, alcohol), including daytime use. Downward dose adjustment of Doral and concomitant CNS depressants should be considered. The potential for adverse drug interactions continues for several days following discontinuation of Doral, until serum levels of both active parent drug and psychoactive metabolites decline.
Use of Doral with other sedative-hypnotics is not recommended. Alcohol generally should not be used during treatment with Doral. The risk of next-day psychomotor impairment is increased if Doral is taken with less than a full night of sleep remaining (7 to 8 hours); if higher than the recommended dose is taken; if co-administered with other CNS depressants.
A withdrawal syndrome similar to that from alcohol (e.g., convulsions, tremor, abdominal and muscle cramps, vomiting, and sweating) can occur following abrupt discontinuation of Doral. The more severe withdrawal effects are usually limited to patients taking higher than recommended doses over an extended time. Abrupt discontinuation should be avoided in such patients, and the dose gradually tapered. Prescribers should monitor patients for tolerance, abuse, and dependence.
Milder withdrawal symptoms (e.g., dysphoria and insomnia) can occur following abrupt discontinuation of benzodiazepines taken at therapeutic levels for short periods.
Because sleep disturbances may be the presenting manifestation of a physical and/or psychiatric disorder, symptomatic treatment of insomnia should be initiated only after a careful evaluation of the patient. The failure of insomnia to remit after 7 to 10 days of treatment may indicate the presence of a primary psychiatric and/or medical illness that should be evaluated. Worsening of insomnia or the emergence of new thinking or behavior abnormalities may be the consequence of an unrecognized psychiatric or physical disorder. Such findings have emerged during the course of treatment with sedative-hypnotic drugs.
Rare cases of angioedema involving the tongue, glottis or larynx have been reported in patients after taking the first or subsequent doses of sedative-hypnotics, including Doral. Some patients have had additional symptoms such as dyspnea, throat closing, or nausea and vomiting that suggest anaphylaxis.
Some patients have required medical therapy in the emergency department. If angioedema involves the tongue, glottis or larynx, airway obstruction may occur and be fatal. Patients who develop angioedema after treatment with Doral should not be rechallenged with the drug.
Abnormal thinking and behavior changes have been reported in patients treated with sedative-hypnotics including Doral. Some of these changes include decreased inhibition, bizarre behavior, and depersonalization. Visual and auditory hallucinations have also been reported. Amnesia, and other neuro-psychiatric symptoms may occur.
Paradoxical reactions such as stimulation, agitation, increased muscle spasticity, and sleep disturbances may occur unpredictably.
Complex behaviors such as "sleep-driving" (i.e., driving while not fully awake, with amnesia for the event) have been reported with use of sedative-hypnotics. These behaviors can occur with initial treatment or in patients previously tolerant of Doral or other sedative-hypnotics. Although these behaviors can occur with use at therapeutic doses, risk is increased by higher doses or concomitant use of alcohol or other CNS depressants. Due to risk to the patient and community, Doral should be discontinued if "sleep-driving" occurs.
Other complex behaviors (e.g., preparing and eating food, making phone calls, or having sex) have been reported in patients who are not fully awake after taking a sedative-hypnotic. As with sleep-driving, patients usually do not remember these events.
Benzodiazepines may worsen depression. Consequently, appropriate precautions (e.g., limiting the total prescription size and increased monitoring for suicidal ideation) should be considered.
The following serious adverse reactions are discussed in greater detail in other sections of the label:
Most common adverse reactions (>1%): drowsiness, headache, fatigue, dizziness, dry mouth, dyspepsia (6.1)

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 practice. The table shows adverse reactions occurring at an incidence of 1% or greater in relatively short-duration, placebo-controlled clinical trials of Doral.

A double-blind, controlled sleep laboratory study (N=30) in elderly patients compared the effects of Doral 7.5 mg and 15 mg to that of placebo over a period of 7 days. Both the 7.5 mg and 15 mg doses appeared to be well tolerated. Caution must be used in interpreting this data due to the small size of the study.
The concomitant use of benzodiazepines and opioids increases the risk of respiratory depression because of actions at different receptor sites in the CNS that control respiration. Benzodiazepines interact at GABAA sites and opioids interact primarily at mu receptors. When benzodiazepines and opioids are combined, the potential for benzodiazepines to significantly worsen opioid-related respiratory depression exists. Limit dosage and duration of concomitant use of benzodiazepines and opioids, and monitor patients closely for respiratory depression and sedation.
Benzodiazepines, including Doral, produce additive CNS depressant effects when co-administered with ethanol or other CNS depressants (e.g. psychotropic medications, anticonvulsants, antihistamines). Downward dose adjustment of Doral and/or concomitant CNS depressants may be necessary because of additive effects.
Pregnancy Category C
There are no adequate and well-controlled studies in pregnant women. Administration of benzodiazepines immediately prior to or during childbirth can result in a syndrome of hypothermia, hypotonia, respiratory depression, and difficulty feeding. In addition, infants born to mothers who have taken benzodiazepines during the later stages of pregnancy can develop dependence, and subsequently withdrawal, during the postnatal period. Although administration of Doral to pregnant animals did not indicate a risk for adverse effects on morphological development at clinically relevant doses, data for other benzodiazepines suggest the possibility of adverse developmental effects (long-term effects on neurobehavioral and immunological function) in animals following prenatal exposure to benzodiazepines. Doral should be used during pregnancy only if the potential benefit justifies the potential risk.
Developmental toxicity studies of Doral in mice at doses up to 400 times the human dose (15 mg) revealed no major drug-related malformations. Minor fetal skeletal variations that occurred were delayed ossification of the sternum, vertebrae, distal phalanges and supraoccipital bones, at doses approximately 70 and 400 times the human dose. A developmental toxicity study of Doral in New Zealand rabbits at doses up to approximately 130 times the human dose demonstrated no effect on fetal morphology or development of offspring.
Doral and its metabolites are excreted in human milk. Caution should be exercised when administering Doral to a nursing woman.
Safety and effectiveness in pediatric patients have not been established.
Doral may cause confusion and over-sedation in the elderly. Elderly patients generally should be started on a low dose of Doral and observed closely. Elderly and debilitated patients may be more sensitive to benzodiazepines, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. A double-blind controlled sleep laboratory study (N=30) compared the effects of Doral 7.5 mg and 15 mg to that of placebo over a period of 7 days. Both the 7.5 mg and 15 mg doses appeared to be well tolerated. Caution must be used in interpreting this data due to the small size of the study.
Doral is classified as a Schedule IV controlled substance by federal regulation.
Addiction-prone individuals (e.g. history of drug addiction or alcoholism) should be under careful surveillance when receiving Doral because of increased risk of abuse and dependence. Benzodiazepine withdrawal symptoms can occur following discontinuation of Doral.
Abuse and addiction are separate and distinct from physical dependence and tolerance. Abuse is characterized by misuse of the drug for non-medical purposes, often in combination with other psychoactive substances. Physical dependence is a state of adaptation that is manifested by a specific withdrawal syndrome that can be produced by abrupt cessation, rapid dose reduction, decreasing blood level of the drug and/or administration of an antagonist. Tolerance is a state of adaptation in which exposure to a drug induces changes that result in a diminution of one or more of the drug’s effects over time. Tolerance may occur to both the desired and undesired effects of drugs and may develop at different rates for different effects.
Addiction is a primary, chronic, neurobiological disease with genetic, psychosocial, and environmental factors influencing its development and manifestations. It is characterized by behaviors that include one or more of the following: impaired control over drug use, compulsive use, continued use despite harm, and craving. Drug addiction is a treatable disease, utilizing a multidisciplinary approach, but relapse is common.
Contact a poison control center for up-to-date information on the management of benzodiazepine overdose.
Manifestations of Doral overdose include somnolence, confusion, and coma. General supportive measures should be employed, along with immediate gastric lavage. Dialysis is of limited value. Flumazenil may be useful, but can contribute to the appearance of neurological symptoms including convulsions. Hypotension may be treated by appropriate medical intervention. Animal experiments suggest that forced diuresis or hemodialysis are of little value in treating Doral overdose. As with the management of intentional overdose with any drug, the possibility of multiple drug ingestion should be considered.
Doral contains Doral, a trifluoroethyl benzodiazepine hypnotic agent, having the chemical name 7-chloro-5- (o-fluoro-phenyl)-1,3-dihydro-1-(2,2,2- trifluoroethyl)-2H-1,4-benzodiazepine-2-thione and the following structural
Doral has the empirical formula C17H11ClF4N2S, and a molecular weight of 386.8. It is a white crystalline compound, soluble in ethanol and insoluble in water.
Each Doral Tablet contains 15 mg of Doral. The inactive ingredients for Doral Tablets include cellulose, corn starch, FD&C Yellow No. 6 Al Lake, lactose, magnesium stearate, silicon dioxide, and sodium lauryl sulfate.
Doral, like other central nervous system agents of the 14-benzodiazepine class, presumably exerts its effects by binding to stereo-specific receptors at several sites within the central nervous system. The exact mechanism of action is unknown.
Absorption
Doral is rapidly (absorption half-life of about 30 minutes) and well absorbed from the gastrointestinal tract. The peak plasma concentration of Doral is approximately 20 ng/mL after a 15 mg dose and occurs at about 2 hours.
Metabolism
Doral, the active parent compound, is extensively metabolized in the liver; two of the plasma metabolites are 2-oxo DORAL and N-desalkyl-2-oxo Doral. All three compounds show CNS depressant activity.
Distribution
The degree of plasma protein binding for Doral and its two major metabolites is greater than 95%.
Elimination
Following administration of 14 C-DORAL, 31% of the dose appeared in the urine and 23% in the feces over five days; only trace amounts of unchanged drug were present in the urine.
The mean elimination half-life of Doral and 2-oxo DORAL is 39 hours and that of N-desalkyl-2-oxo DORAL is 73 hours. Steady-state levels of Doral and 2-oxo DORAL are attained by the seventh daily dose and that of N-desalkyl-2-oxo DORAL by the thirteenth daily dose.
Special Populations
Geriatrics: The pharmacokinetics of Doral and 2-oxo DORAL in geriatric subjects are comparable to those seen in young adults; as with desalkyl metabolites of other benzodiazepines, the elimination half-life of N-desalkyl-2-oxo DORAL in geriatric patients is about twice that of young adults.
Drug Interactions
Bupropion (a CYP2B6 substrate): Co-administration of a single dose of 150 mg Bupropion Hydrochloride XL with steady state Doral did not significantly affect the AUC and Cmax of bupropion or its primary metabolite, hydroxybupropion.
Carcinogenesis
Doral showed no evidence of carcinogenicity in oral carcinogenicity studies in mice and hamsters.
Mutagenesis
Doral was negative in the bacterial reverse mutation (Ames) assay and equivocal in the mouse lymphoma tk assay.
Impairment of Fertility
Reproduction studies in mice conducted with Doral at doses equal to 60 and
180 times the human dose of 15 mg produced slight reductions in fertility rate. Similar reductions in fertility rate have been reported in mice dosed with other benzodiazepines, and is believed to be related to the sedative effects of these drugs at high doses
The effectiveness of Doral was established in placebo-controlled clinical studies of 5 nights duration in acute and chronic insomnia. The sustained effectiveness of Doral was established in chronic insomnia in a sleep laboratory (polysomnographic) study of 28 nights duration. In the sleep laboratory study, Doral significantly decreased sleep latency and total wake time, and significantly increased total sleep time and percent sleep time, for one or more nights.
Doral 15 mg was effective on the first night of administration. Sleep latency, total wake time and wake time after sleep onset were still decreased and percent sleep time was still increased for several nights after the drug was discontinued. Percent slow wave sleep was decreased, and REM sleep was essentially unchanged. No transient sleep disturbance, such as “rebound insomnia,” was observed after withdrawal of the drug in sleep laboratory studies in 12 patients using 15 mg doses.
A double-blind, controlled sleep laboratory study (N=30) in elderly patients compared the effects of Doral 7.5 mg and 15 mg to that of placebo over a period of 7 days. Both the 7.5 mg and 15 mg doses appeared to be effective. Caution must be used in interpreting this data due to the small size of the study.

Store Doral Tablets at controlled room temperature 20°-25°C (68°-77°F).
Inform patients and caregivers that potentially fatal additive effects may occur if Doral is used with opioids and not to use such drugs concomitantly unless supervised by a healthcare provider
Inform patients about the benefits and risks of Doral, stressing the importance of use as directed. Assist patients in understanding the Medication Guide and instruct them to read it with each prescription refill.
CNS depressant Effects and Next-Day Impairment
Tell patients that DORAL can cause next-day impairment, even in the absence of symptoms. Caution patients against driving or engaging in other hazardous activities or activities requiring complete mental alertness when using Doral. Tell patients that daytime impairment may persist for several days following discontinuation of Doral.
Withdrawal
Instruct patients to contact you before stopping or decreasing the dose of Doral, because withdrawal symptoms can occur.
Abnormal thinking and behavior change
Instruct patients that sedative hypnotics can cause abnormal thinking and behavior change, including “sleep-driving” and other complex behaviors while not being fully awake (preparing and eating food, making phone calls, or having sex). Tell patients to call you immediately if they develop any of these symptoms.
Severe Allergic Reactions
Inform patients that severe allergic reactions can occur from Doral. Describe the signs/symptoms of these reactions and advise patients to seek medical attention immediately if these occur.
Suicide
Tell patients that Doral can worsen depression, and to immediately report any suicidal thoughts.
Alcohol and other drugs
Ask patients about alcohol consumption, medicines they are taking now, and drugs they may be taking without a prescription. Advise patients that alcohol generally should not be used during treatment with Doral.
Pregnancy
Instruct patients to inform you if they are nursing or pregnant, or may become pregnant while taking Doral.
Tolerance, Abuse, and Dependence
Tell patients not to increase the dose of Doral on their own, and to inform you if they believe the drug “does not work”.

Depending on the reaction of the Doral after taken, if you are feeling dizziness, drowsiness or any weakness as a reaction on your body, Then consider Doral not safe to drive or operate heavy machine after consumption. Meaning that, do not drive or operate heavy duty machines after taking the capsule if the capsule has a strange reaction on your body like dizziness, drowsiness. As prescribed by a pharmacist, it is dangerous to take alcohol while taking medicines as it exposed patients to drowsiness and health risk. Please take note of such effect most especially when taking Primosa capsule. It's advisable to consult your doctor on time for a proper recommendation and medical consultations.
Is Doral addictive or habit forming?Medicines are not designed with the mind of creating an addiction or abuse on the health of the users. Addictive Medicine is categorically called Controlled substances by the government. For instance, Schedule H or X in India and schedule II-V in the US are controlled substances.
Please consult the medicine instruction manual on how to use and ensure it is not a controlled substance.In conclusion, self medication is a killer to your health. Consult your doctor for a proper prescription, recommendation, and guidiance.
