Boxed Warning:
Suicidality and antidepressant drugs 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. anyone considering the use of doxepin hydrochloride or any other antidepressant in a child, adolescent, or young adult must balance this risk with the clinical need. short-term studies did not show an increase in the risk of suicidality with antidepressants compared to placebo in adults beyond age 24; there was a reduction in risk with antidepressants compared to placebo in adults aged 65 and older. depression and certain other psychiatric disorders are themselves associated with increases in the risk of suicide. patients of all ages who are started on antidepressant therapy should be monitored appropriately and observed closely for clinical worsening, suicidality, or unusual changes in behavior. families and caregivers should be advised of the need for close observation and communication with the prescriber. doxepin hydrochloride is not approved for use in pediatric patients. (see warnings: clinical worsening and suicide risk , precautions: information for patients , and precautions: pediatric use )
Indications and Usage:
Indications doxepin hydrochloride capsules, usp are recommended for the treatment of: psychoneurotic patients with depression and/or anxiety. depression and/or anxiety associated with alcoholism (not to be taken concomitantly with alcohol). depression and/or anxiety associated with organic disease (the possibility of drug interaction should be considered if the patient is receiving other drugs concomitantly). psychotic depressive disorders with associated anxiety including involutional depression and manic-depressive disorders. the target symptoms of psychoneurosis that respond particularly well to doxepin hydrochloride capsules include anxiety, tension, depression, somatic symptoms and concerns, sleep disturbances, guilt, lack of energy, fear, apprehension and worry. clinical experience has shown that doxepin hydrochloride capsules are safe and well tolerated even in the elderly patient. owing to lack of clinical experience in the pediatric population, doxepin hydrochloride capsules a

Warnings:
Warnings clinical worsening and suicide risk patients with major depressive disorder (mdd), both adult and pediatric, may experience worsening of their depression and/or the emergence of suicidal ideation and behavior (suicidality) or unusual changes in behavior, whether or not they are taking antidepressant medications, and this risk may persist until significant remission occurs. suicide is a known risk of depression and certain other psychiatric disorders, and these disorders themselves are the strongest predictors of suicide. there has been a long-standing concern, however, that antidepressants may have a role in inducing worsening of depression and the emergence of suicidality in certain patients during the early phases of treatment. pooled analyses of short-term placebo-controlled trials of antidepressant drugs (ssris and others) showed that these drugs increase the risk of suicidal thinking and behavior (suicidality) in children, adolescents, and young adults (ages 18 to 24) wit

there was a reduction with antidepressants compared to placebo in adults aged 65 and older. the pooled analyses of placebo-controlled trials in children and adolescents with mdd, obsessive compulsive disorder (ocd), or other psychiatric disorders included a total of 24 short-term trials of nine antidepressant drugs in over 4,400 patients. the pooled analyses of placebo-controlled trials in adults with mdd or other psychiatric disorders included a total of 295 short-term trials (median duration of 2 months) of 11 antidepressant drugs in over 77,000 patients. there was considerable variation in risk of suicidality among drugs, but a tendency toward an increase in the younger patients for almost all drugs studied. there were differences in absolute risk of suicidality across the different indications, with the highest incidence in mdd. the risk differences (drug vs. placebo), however, were relatively stable within age strata and across indications. these risk differences (drug-placebo difference in the number of cases of suicidality per 1,000 patients treated) are provided in table 1 . table 1 age range drug-placebo difference in number of cases of suicidality per 1,000 patients treated increases compared to placebo < 18 14 additional cases 18 to 24 5 additional cases decreases compared to placebo 25 to 64 1 fewer case ⥠65 6 fewer cases no suicides occurred in any of the pediatric trials. there were suicides in the adult trials, but the number was not sufficient to reach any conclusion about drug effect on suicide. it is unknown whether the suicidality risk extends to longer-term use, i.e., beyond several months. however, there is substantial evidence from placebo-controlled maintenance trials in adults with depression that the use of antidepressants can delay the recurrence of depression. all patients being treated with antidepressants for any indication should be monitored appropriately and observed closely for clinical worsening, suicidality and unusual changes in behavior, especially during the initial few months of a course of drug therapy, or at times of dose changes, either increases or decrease. the following symptoms, anxiety, agitation, panic attacks, insomnia, irritability, hostility, aggressiveness, impulsivity, akathisia (psychomotor restlessness), hypomania and mania, have been reported in adult and pediatric patients being treated with antidepressants for major depressive disorder as well as for other indications, both psychiatric and nonpsychiatric. although a causal link between the emergence of such symptoms and either the worsening of depression and/or the emergence of suicidal impulses has not been established, there is concern that such symptoms may represent precursors to emerging suicidality. consideration should be given to changing the therapeutic regimen, including possibly discontinuing the medication, in patients whose depression is persistently worse, or who are experiencing emergent suicidality or symptoms that might be precursors to worsening depression or suicidality, especially if these symptoms are severe, abrupt in onset, or were not part of the patientâs presenting symptoms. families and caregivers of patients being treated with antidepressants for major depressive disorder or other indications, both psychiatric and nonpsychiatric, should be alerted about the need to monitor patients for the emergence of agitation, irritability, unusual changes in behavior, and the other symptoms described above, as well as the emergence of suicidality, and to report such symptoms immediately to healthcare providers. such monitoring should include daily observation by families and caregivers. prescriptions for doxepin hydrochloride should be written for the smallest number of capsules consistent with good patient management, in order to reduce the risk of overdose. screening patients for bipolar disorder: a major depressive episode may be the initial presentation of bipolar disorder. it is generally believed (though not established in controlled trials) that treating such an episode with an antidepressant alone may increase the likelihood of precipitation of a mixed/manic episode in patients at risk for bipolar disorder. whether any of the symptoms described above represent such a conversion is unknown. however, prior to initiating treatment with an antidepressant, patients with depressive symptoms should be adequately screened to determine if they are at risk for bipolar disorder; such screening should include a detailed psychiatric history, including a family history of suicide, bipolar disorder, and depression. it should be noted that doxepin hydrochloride is not approved for use in treating bipolar depression. angle-closure glaucoma: the pupillary dilation that occurs following use of many antidepressant drugs including doxepin hydrochloride capsules may trigger an angle closure attack in a patient with anatomically narrow angles who does not have a patent iridectomy. usage in geriatric: the use of doxepin hydrochloride on a once a day dosage regimen in geriatric patients should be adjusted carefully based on the patient's condition (see precautions-geriatric use ). usage in pregnancy: reproduction studies have been performed in rats, rabbits, monkeys and dogs and there was no evidence of harm to the animal fetus. the relevance to humans is not known. since there is no experience in pregnant women who have received this drug, safety in pregnancy has not been established. there has been a report of apnea and drowsiness occurring in a nursing infant whose mother was taking doxepin hydrochloride. usage in children: the use of doxepin hydrochloride in children under 12 years of age is not recommended because safe conditions for its use have not been established.
Dosage and Administration:
Dosage and administration for most patients with illness of mild to moderate severity, a starting daily dose of 75 mg is recommended. dosage may subsequently be increased or decreased at appropriate intervals and according to individual response. the usual optimum dose range is 75 mg/day to 150 mg/day. in more severely ill patients higher doses may be required with subsequent gradual increase to 300 mg/day if necessary. additional therapeutic effect is rarely to be obtained by exceeding a dose of 300 mg/day. in patients with very mild symptomatology or emotional symptoms accompanying organic disease, lower doses may suffice. some of these patients have been controlled on doses as low as 25â50 mg/day. the total daily dosage of doxepin hydrochloride may be given on a divided or once-a-day dosage schedule. if the once-a-day schedule is employed, the maximum recommended dose is 150 mg/day. this dose may be given at bedtime. the 150 mg capsule strength is intended for maintenance thera

Contraindications:
Contraindications doxepin hydrochloride capsules are contraindicated in individuals who have shown hypersensitivity to the drug. possibility of cross sensitivity with other dibenzoxepines should be kept in mind. doxepin hydrochloride capsules are contraindicated in patients with glaucoma or a tendency to urinary retention. these disorders should be ruled out, particularly in older patients.
Adverse Reactions:
Adverse reactions note: some of the adverse reactions noted below have not been specifically reported with doxepin hydrochloride use. however, due to the close pharmacological similarities among the tricyclics, the reactions should be considered when prescribing doxepin hydrochloride. anticholinergic effects: dry mouth, blurred vision, constipation and urinary retention have been reported. if they do not subside with continued therapy or become severe, it may be necessary to reduce the dosage. central nervous system effects: drowsiness is the most commonly noticed side effect. this tends to disappear as therapy is continued. other infrequently reported cns side effects are confusion, disorientation, hallucinations, numbness, paresthesias, ataxia, extrapyramidal symptoms, seizures, tardive dyskinesia and tremor. cardiovascular: cardiovascular effects including hypotension, hypertension and tachycardia have been reported occasionally. allergic: skin rash, edema, photosensitization and pr

(see anticholinergic effects .) endocrine: raised or lowered libido, testicular swelling, gynecomastia in males, enlargement of breasts and galactorrhea in the female, raising or lowering of blood sugar levels and syndrome of inappropriate antidiuretic hormone secretion have been reported with tricyclic administration. other: dizziness, tinnitus, weight gain, sweating, chills, fatigue, weakness, flushing, jaundice, alopecia, headache, exacerbation of asthma, angle closure glaucoma, mydriasis and hyperpyrexia (in association with chlorpromazine) have been occasionally observed as adverse effects. withdrawal symptoms: the possibility of development of withdrawal symptoms upon abrupt cessation of treatment after prolonged doxepin hydrochloride administration should be borne in mind. these are not indicative of addiction and gradual withdrawal of medication should not cause these symptoms.
Overdosage:
Overdosage deaths may occur from overdosage with this class of drugs. multiple drug ingestion (including alcohol) is common in deliberate tricyclic antidepressant overdose. as the management is complex and changing, it is recommended that the physician contact a poison control center for current information on treatment. signs and symptoms of toxicity develop rapidly after tricyclic antidepressant overdose; therefore, hospital monitoring is required as soon as possible. manifestations: critical manifestations of overdose include: cardiac dysrhythmias, severe hypotension, convulsions and cns depression, including coma. changes in the electrocardiogram, particularly in qrs axis or width, are clinically significant indicators of tricyclic antidepressant toxicity. other signs of overdose may include: confusion, disturbed concentration, transient visual hallucinations, dilated pupils, agitation, hyperactive reflexes, stupor, drowsiness, muscle rigidity, vomiting, hypothermia, hyperpyrexia, or any of the symptoms listed under adverse reactions . deaths have been reported involving overdoses of doxepin. general recommendations: general: obtain an ecg and immediately initiate cardiac monitoring. protect the patient's airway, establish an intravenous line and initiate gastric decontamination. a minimum of 6 hours of observation with cardiac monitoring and observation for signs of cns or respiratory depression, hypotension, cardiac dysrhythmias and/or conduction blocks, and seizures is strongly advised. if signs of toxicity occur at any time during this period, extended monitoring is recommended. there are case reports of patients succumbing to fatal dysrhythmias late after overdose; these patients had clinical evidence of significant poisoning prior to death and most received inadequate gastrointestinal decontamination. monitoring of plasma drug levels should not guide management of the patient. gastrointestinal decontamination: all patients suspected of tricyclic antidepressant overdose should receive gastrointestinal decontamination. this should include large volume gastric lavage followed by activated charcoal. if consciousness is impaired, the airway should be secured prior to lavage. emesis is contraindicated. cardiovascular: a maximal limb lead qrs duration of ⥠0.10 seconds may be the best indication of the severity of the overdose. intravenous sodium bicarbonate should be used to maintain the serum ph in the range of 7.45 to 7.55. if the ph response is inadequate, hyperventilation may also be used. concomitant use of hyperventilation and sodium bicarbonate should be done with extreme caution, with frequent ph monitoring. a ph > 7.60 or a pco 2 < 20 mm hg is undesirable. dysrhythmias unresponsive to sodium bicarbonate therapy/hyperventilation may respond to lidocaine, bretylium or phenytoin. type 1a and 1c antiarrhythmics are generally contraindicated (e.g., quinidine, disopyramide and procainamide). in rare instances, hemoperfusion may be beneficial in acute refractory cardiovascular instability in patients with acute toxicity. however, hemodialysis, peritoneal dialysis, exchange transfusions and forced diuresis generally have been reported as ineffective in tricyclic antidepressant poisoning. cns: in patients with cns depression, early intubation is advised because of the potential for abrupt deterioration. seizures should be controlled with benzodiazepines, or if these are ineffective, other anticonvulsants (e.g., phenobarbital, phenytoin). physostigmine is not recommended except to treat life threatening symptoms that have been unresponsive to other therapies, and then only in consultation with a poison control center. psychiatric follow-up: since overdosage is often deliberate, patients may attempt suicide by other means during the recovery phase. psychiatric referral may be appropriate. pediatric management: the principles of management of child and adult overdosages are similar. it is strongly recommended that the physician contact the local poison control center for specific pediatric treatment.

Clinical Pharmacology:
Chemistry doxepin hydrochloride is a dibenzoxepin derivative and is the first of a family of tricyclic psychotherapeutic agents. specifically, it is an isomeric mixture of 1-propanamine, 3-dibenz[ b,e ]oxepin-11 (6 h )ylidene- n,n -dimethyl-hydrochloride. doxepin hydrochloride
Clinical Studies:
Actions the mechanism of action of doxepin hydrochloride is not definitely known. it is not a central nervous system stimulant nor a monoamine oxidase inhibitor. the current hypothesis is that the clinical effects are due, at least in part, to influences on the adrenergic activity at the synapses so that deactivation of norepinephrine by reuptake into the nerve terminals is prevented. animal studies suggest that doxepin hydrochloride does not appreciably antagonize the antihypertensive action of guanethidine. in animal studies anticholinergic, antiserotonin and antihistamine effects on smooth muscle have been demonstrated. at higher than usual clinical doses norepinephrine response was potentiated in animals. this effect was not demonstrated in humans. at clinical dosages up to 150 mg per day, doxepin hydrochloride can be given to man concomitantly with guanethidine and related compounds without blocking the antihypertensive effect. at dosages above 150 mg per day blocking of the antih
