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 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 is not approved for use in pediatric patients. (See WARNINGS: Clinical Worsening and Suicide Risk, PRECAUTIONS: Information for Patients and PRECAUTIONS: Pediatric Use.)
DOXEPIN HYDROCHLORIDE CAPSULES, USP
Doxepin hydrochloride is one of a class of psychotherapeutic agents known as dibenzoxepin tricyclic compounds.
Doxepin is indicated for the following:
Doxepin is 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 include anxiety, tension, depression, somatic symptoms and concerns, sleep disturbances, guilt, lack of energy, fear, apprehension and worry.
Clinical experience has shown that doxepin is safe and well-tolerated even in the elderly patient. Owing to lack of clinical experience in the pediatric population, doxepin is not recommended for use in children under 12 years of age.
Published Studies Related to Doxepin
Efficacy and safety of doxepin 3 and 6 mg in a 35-day sleep laboratory trial in adults with chronic primary insomnia. [2011.10.01]
STUDY OBJECTIVES: To evaluate the efficacy and safety of doxepin (DXP) 3 mg and 6 mg in adults diagnosed with primary insomnia... CONCLUSIONS: Five weeks of nightly administration of DXP 3 mg and 6 mg to adults with chronic primary insomnia resulted in significant and sustained improvements in sleep maintenance and early morning awakenings (with the exception of SE in the final quarter of the night on N29 for 3 mg [P=0.0691]). These sleep improvements were not accompanied by next-day residual effects or followed by rebound insomnia or withdrawal effects upon discontinuation. These findings confirm the unique profile of sleep maintenance efficacy and safety of DXP observed in prior studies.
Doxepin cream vs betamethasone cream for treatment of chronic skin lesions due to sulfur mustard. [2011.05]
Oral doxepin was shown to reduce chronic pruritus due to sulfur mustard. The present study compared the effects of topical doxepin 5% with betamethasone 1% for the treatment of pruritus in veterans exposed to sulfur mustard...
Efficacy and Safety of Doxepin 1 mg and 3 mg in a 12-week Sleep Laboratory and Outpatient Trial of Elderly Subjects with Chronic Primary Insomnia. [2010.11]
STUDY OBJECTIVES: to evaluate the efficacy and safety of doxepin 1 mg and 3 mg in elderly subjects with chronic primary insomnia... CONCLUSIONS: DXP 1 mg and 3 mg administered nightly to elderly chronic insomnia patients for 12 weeks resulted in significant and sustained improvements in most endpoints. These improvements were not accompanied by evidence of next-day residual sedation or other significant adverse effects. DXP also demonstrated improvements in both patient- and physician-based ratings of global insomnia outcome. The efficacy of DXP at the doses used in this study is noteworthy with respect to sleep maintenance and early morning awakenings given that these are the primary sleep complaints of the elderly. This study, the longest placebo-controlled, double-blind, polysomnographic trial of nightly pharmacotherapy for insomnia in the elderly, provides the best evidence to date of the sustained efficacy and safety of an insomnia medication in older adults.

Low-dose doxepin for treatment of pruritus in patients on hemodialysis. [2007.07]
INTRODUCTION. Pruritus is one of the frequent discomforting complications in patients with end-stage renal disease.A low dose of doxepin is safe while effective and its main adverse effect, drowsiness, is temporary and can be easily tolerated by the patients.

The Treatment of Insomnia in Patients With HIV Disease [Recruiting]
This study is designed to evaluate the efficacy of two commonly prescribed sleep aids for
use in patients who are HIV positive and suffer from insomnia.
Treatments for Insomnia in Patients With Parkinson's Disease [Recruiting]
More than half of patients with Parkinson's have troubles with insomnia. There are several
treatment options for insomnia that have been studied in the general population - however,
the investigators don't know if these treatments work for patients with Parkinson's. It is
possible that people with Parkinson's may have different treatment responses.
The goal of this project is to test in a pilot study the tolerability and effectiveness of
pharmacologic and non-pharmacologic treatments to improve insomnia in patients with
Parkinson's disease. Each participant in this study will be wearing a wrist actigrapch and
fill out the sleep diary. Three main treatment strategies will be tested: Placebo Light
therapy, Cognitive behavioural therapy and active light therapy, and insomnia medications.
The treatment that each person will receive first will be chosen randomly. If the first
therapy has not been effective, participant may choose to re-enrol in the trial with one of
the remaining two therapies.
Treatment-Resistant Depression, Hippocampus Atrophy and Serotonin Genetic Polymorphism [Recruiting]
Reduction of volume of the hippocampus has been associated with major depression in many
studies. It has been suggested that antidepressants may protect against hippocampus volume
loss in humans associated with multiple episodes of depression and may also reverse the
reduction of volume caused by the depression. In addition, genetic markers for serotonin are
implicated with depression, and may be an indication of reduced response to antidepressant
This study aims to enroll patients who are defined as having treatment resistant depression
(no remission after at least 2 treatments trials with an antidepressant). They will receive
an MRI scan at the initial visit and either 6 months after sustained remission or 12 months
after they enter the study for non-remitters. They will also be asked to give a blood sample
for genotyping. They will be matched by age and handedness to healthy volunteers with no
personal history of depression who will also receive an MRI scan and genotyping.
The first aim is to compare hippocampal volume of depressed subjects to healthy controls. It
is anticipated that subjects will initially have smaller hippocampal volume but of those who
sustain remission, there will be a small increase in hippocampal volume. It is also
anticipated that specific genetic markers will be related to individuals response to
