## Linked label clinical facts

These facts come from the highest-confidence linked drug label for this NDC entry. Prefer them for questions about uses, warnings, side effects, and storage.
**Use:** Doxepin tablets are indicated for the treatment of insomnia characterized by difficulty with sleep maintenance. The clinical trials performed in support of efficacy were up to 3 months in duration. Doxepin tablets are indicated for the treatment of insomnia characterized by difficulties with sleep maintenance. ( 1 , 14 )
**Description:** Doxepin Tablets are available in 3 mg and 6 mg strengths for oral administration. Each tablet contains 3.39 mg or 6.78 mg doxepin hydrochloride USP, equivalent to 3 mg and 6 mg of doxepin, respectively. Chemically, doxepin hydrochloride, USP is an (E) and (Z) geometric, isomeric mixture of 1 propanamine, 3-dibenz[ b,e ]oxepin-11(6 H )ylidene- N , N -dimethyl-hydrochloride. It has the following structure: Doxepin hydrochloride, USP is a white crystalline powder, with a slight amine-like odor, that is readily soluble in water. It has a molecular weight of 315.84 and molecular formula of C 19 H 21 NO•HCl. Each doxepin tablet includes the following inactive ingredients: colloidal silicon dioxide, croscarmellose sodium, dibasic calcium phosphate anhydrous, hypromellose, magnesium stearate, microcrystalline cellulose, and titanium dioxide. The 3 mg tablet also contains polyethylene glycol 400. The 6 mg tablet also contains FD&C Blue # 2 Aluminum Lake, FD&C Red # 40 Aluminum Lake, FD&C Yellow # 6 Aluminum Lake (Sunset Yellow Lake), and triacetin. 5c3be85e-figure-02
**Dosage and administration:** The dose of doxepin tablets should be individualized. Initial dose: 6 mg, once daily for adults ( 2.1 ) and 3 mg, once daily for the elderly. ( 2.1 , 2.2 ) Take within 30 minutes of bedtime. Total daily dose should not exceed 6 mg. ( 2.3 ) Should not be taken within 3 hours of a meal. ( 2.3 , 12.3 ) 2.1 Dosing in Adults The recommended dose of doxepin tablets for adults is 6 mg once daily. A 3 mg once daily dose may be appropriate for some patients, if clinically indicated. 2.2 Dosing in the Elderly The recommended starting dose of doxepin tablets in elderly patients (≥ 65 years old) is 3 mg once daily. The daily dose can be increased to 6 mg, if clinically indicated. 2.3 Administration Doxepin tablets should be taken within 30 minutes of bedtime. To minimize the potential for next day effects, doxepin tablets should not be taken within 3 hours of a meal [ see Clinical Pharmacology ( 12.3 )]. The total doxepin tablets dose should not exceed 6 mg per day.
**Warnings:** Need to Evaluate for Co-morbid Diagnoses: Reevaluate if insomnia persists after 7 to 10 days of use. ( 5.1 ) Abnormal thinking, behavioral changes, complex behaviors: May include “Sleep-driving” and hallucinations. Immediately evaluate any new onset behavioral changes. ( 5.2 ) Depression: Worsening of depression or suicidal thinking may occur. Prescribe the least amount feasible to avoid intentional overdose. ( 5.3 ) CNS-depressant effects: Use can impair alertness and motor coordination. Avoid engaging in hazardous activities such as operating a motor vehicle or heavy machinery after taking drug. ( 5.4 ) Do not use with alcohol. ( 5.4 , 7.3 ) Potential additive effects when used in combination with CNS depressants or sedating antihistamines. Dose reduction may be needed. ( 5.4 , 7.4 ) Patients with severe sleep apnea: Doxepin is ordinarily not recommended for use in this population. ( 8.7 ) 5.1 Need to Evaluate for Comorbid Diagnoses Because sleep disturbances may be the presenting manifestation of a physical and/or psychiatric disorder, symptomatic treatment of insomnia should be initiated only after 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. Exacerbation of insomnia or the emergence of new cognitive or behavioral abnormalities may be the consequence of an unrecognized psychiatric or physical disorder. Such findings have emerged during the course of treatment with hypnotic drugs. 5.2 Abnormal Thinking and Behavioral Changes Complex behaviors such as “sleep-driving” (i.e., driving while not fully awake after ingestion of a hypnotic, with amnesia for the event) have been reported with hypnotics. These events can occur in hypnotic-naive as well as in hypnotic-experienced persons. Although behaviors such as “sleep-driving” may occur with hypnotics alone at therapeutic doses, the use of alcohol and other CNS depressants with hypnotics appears to increase the risk of such behaviors, as does the use of hypnotics at doses exceeding the maximum recommended dose. Due to the risk to the patient and the community, discontinuation of doxepin should be strongly considered for patients who report a “sleep-driving” episode. 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 hypnotic. As with “sleep-driving”, patients usually do not remember these events. Amnesia, anxiety and other neuro-psychiatric symptoms may occur unpredictably. 5.3 Suicide Risk and Worsening of Depression In primarily depressed patients, worsening of depression, including suicidal thoughts and actions (including completed suicides), has been reported in association with the use of hypnotics. Doxepin, the active ingredient in doxepin tablets, is an antidepressant at doses 10- to 100-fold higher than in doxepin tablets. Antidepressants increased the risk compared to placebo of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults in short-term studies of major depressive disorder (MDD) and other psychiatric disorders. Risk from the lower dose of doxepin in doxepin tablets can not be excluded. It can rarely be determined with certainty whether a particular instance of the abnormal behaviors listed above is drug induced, spontaneous in origin, or a result of an underlying psychiatric or physical disorder. Nonetheless, the emergence of any new behavioral sign or symptom of concern requires careful and immediate evaluation. 5.4 CNS Depressant Effects After taking doxepin, patients should confine their activities to those necessary to prepare for bed. Patients should avoid engaging in hazardous activities, such as operating a motor vehicle or heavy machinery, at night after taking doxepin, and should be cautioned about potential impairment in the performance of such activities that may occur the day following ingestion. When taken with doxepin, the sedative effects of alcoholic beverages, sedating antihistamines, and other CNS depressants may be potentiated [ see Warnings and Precautions ( 5.2 ) and Drug Interactions ( 7.3 , 7.4) ]. Patients should not consume alcohol with doxepin [ see Warnings and Precautions ( 5.2 ) and Drug Interactions ( 7.3 ) ]. Patients should be cautioned about potential additive effects of doxepin used in combination with CNS depressants or sedating antihistamines [ see Warnings and Precautions ( 5.2 ) and Drug Interactions ( 7.4) ].
**Contraindications:** Hypersensitivity to doxepin hydrochloride, inactive ingredients, or other dibenzoxepines. ( 4.1 ) Co-administration with Monoamine Oxidase Inhibitors (MAOIs): Do not administer if patient is taking MAOIs or has used MAOIs within the past two weeks. ( 4.2 ) Untreated narrow angle glaucoma or severe urinary retention. ( 4.3 ) 4.1 Hypersensitivity Doxepin is contraindicated in individuals who have shown hypersensitivity to doxepin HCl, any of its inactive ingredients, or other dibenzoxepines. 4.2 Co-administration with Monoamine Oxidase Inhibitors (MAOIs) Serious side effects and even death have been reported following the concomitant use of certain drugs with MAO inhibitors. Do not administer doxepin if patient is currently on MAOIs or has used MAOIs within the past two weeks. The exact length of time may vary depending on the particular MAOI dosage and duration of treatment. 4.3 Glaucoma and Urinary Retention Doxepin is contraindicated in individuals with untreated narrow angle glaucoma or severe urinary retention.
**Adverse reactions:** The following serious adverse reactions are discussed in greater detail in other sections of labeling: • Abnormal thinking and behavioral changes [ see Warnings and Precautions ( 5.2 ) ]. • Suicide risk and worsening of depression [ see Warnings and Precautions ( 5.3) ]. • CNS Depressant effects [ see Warnings and Precautions ( 5.4 ) ]. The most common treatment-emergent adverse reactions, reported in ≥ 2% of patients treated with doxepin, and more commonly than in patients treated with placebo, were somnolence/sedation, nausea, and upper respiratory tract infection.

Because clinical studies 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. However, data from the doxepin studies provide the physician with a basis for estimating the relative contributions of drug and non-drug factors to adverse reaction incidence rates in the populations studied. Associated with Discontinuation of Treatment The percentage of subjects discontinuing Phase 1, 2, and 3 trials for an adverse reaction was 0.6% in the placebo group compared to 0.4%, 1.0%, and 0.7% in the doxepin 1 mg, 3 mg, and 6 mg groups, respectively. No reaction that resulted in discontinuation occurred at a rate greater than 0.5%. Adverse Reactions Observed at an Incidence of ≥ 2% in Controlled Trials Table 1 shows the incidence of treatment-emergent adverse reactions from three long-term (28 to 85 days) placebo-controlled studies of doxepin in adult (N=221) and elderly (N=494) subjects with chronic insomnia. Reactions reported by Investigators were classified using a modified MedDRA dictionary of preferred terms for purposes of establishing incidence. The table includes only reactions that occurred in 2% or more of subjects who received doxepin 3 mg or 6 mg in which the incidence in subjects treated with doxepin was greater than the incidence in placebo-treated subjects. Table 1 Incidence (%) of Treatment-Emergent Adverse Reactions in Long-term Placebo-Controlled Clinical Trials System Organ Class Preferred Term* Placebo (N=278) Doxepin 3 mg (N=157) Doxepin 6 mg (N=203) * Includes reactions that occurred at a rate of ≥ 2% in any doxepin-treated group and at a higher rate than placebo. Nervous System Disorders Somnolence/Sedation 4 6 9 Infections and Infestations Upper Respiratory Tract Infection/Nasopharyngitis 2 4 2 Gastroenteritis 0 2 0 Gastrointestinal Disorders Nausea 1 2 2 Vascular Disorders Hypertension 0 3 < 1 The most common treatment-emergent adverse reaction in the placebo and each of the doxepin dose groups was somnolence/sedation. 6.2 Studies Pertinent to Safety Concerns for Sleep-promoting Drugs Residual Pharmacological Effect in Insomnia Trials Five randomized, placebo-controlled studies in adults and the elderly assessed next-day psychomotor function within 1 hour of awakening utilizing the digit-symbol substitution test (DSST), symbol copying test (SCT), and visual analog scale (VAS) for sleepiness, following night time administration of doxepin. In a one-night, double-blind study conducted in 565 healthy adult subjects experiencing transient insomnia, doxepin 6 mg showed modest negative changes in SCT and VAS. In a 35-day, double-blind, placebo-controlled, parallel group study of doxepin 3 and 6 mg in 221 adults with chronic insomnia, small decreases in the DSST and SCT occurred in the 6 mg group. In a 3-month, double-blind, placebo-controlled, parallel group study in 240 elderly subjects with chronic insomnia, doxepin 1 mg and 3 mg was comparable to placebo on DSST, SCT, and VAS. 6.3 Other Reactions Observed During the Pre-marketing Evaluation of Doxepin Doxepin was administered to 1017 subjects in clinical trials in the United States. Treatment-emergent adverse reactions recorded by clinical investigators were standardized using a modified MedDRA dictionary of preferred terms. The following is a list of MedDRA terms that reflect treatment-emergent adverse reactions reported by subjects treated with doxepin. Adverse reactions are further categorized by body system and listed in order of decreasing frequency according to the following definitions: Frequent adverse reactions are those that occurred on one or more occasions in at least 1/100 subjects; Infrequent adverse reactions are those that occurred in fewer than 1/100 subjects and more than 1/1000 subjects.

( 7.5 ) 7.1 Cytochrome P450 Isozymes Doxepin is primarily metabolized by hepatic cytochrome P450 isozymes CYP2C19 and CYP2D6, and to a lesser extent, by CYP1A2 and CYP2C9. Inhibitors of these isozymes may increase the exposure of doxepin. Doxepin is not an inhibitor of any CYP isozymes at therapeutically relevant concentrations. The ability of doxepin to induce CYP isozymes is not known. 7.2 Cimetidine Doxepin exposure is doubled with concomitant administration of cimetidine, a nonspecific inhibitor of CYP isozymes. A maximum dose of 3 mg is recommended in adults and elderly when cimetidine is co-administered with doxepin [ see Clinical Pharmacology ( 12.3) ] 7.3 Alcohol When taken with doxepin, the sedative effects of alcohol may be potentiated [ see Warnings and Precautions ( 5.2 , 5.4) ]. 7.4 CNS Depressants and Sedating Antihistamines When taken with doxepin, the sedative effects of sedating antihistamines and CNS depressants may be potentiated [ see Warnings and Precautions ( 5.2 , 5.4 ) ]. 7.5 Tolazamide A case of severe hypoglycemia has been reported in a type II diabetic patient maintained on tolazamide (1 g/day) 11 days after the addition of oral doxepin (75 mg/day).
