Doxepin: what it is and when people use it

Doxepin is a tricyclic antidepressant that treats depression, anxiety, and some sleep problems. Low-dose doxepin also helps with insomnia (brand Silenor in some countries) and topical doxepin cream relieves severe itching. It works by changing brain chemicals that affect mood and sleep.

Want to know if it fits your situation? Talk with your doctor. Doxepin is prescription-only for a reason: doses and safety checks vary by condition and by person.

How people take doxepin

Oral doses for depression or anxiety usually start low and increase. Typical adult ranges are about 75–150 mg a day, though some people need different amounts; very high doses may be used in certain cases under close supervision. For sleep, doctors may prescribe 3–6 mg at bedtime (low-dose formulation). Topical cream for itch is applied as directed by a clinician.

Take doxepin at the same time each day. If it makes you sleepy, taking it at night helps. Don’t stop suddenly—your doctor will give a taper plan to avoid withdrawal symptoms like agitation, sweating, or trouble sleeping.

Side effects, interactions, and safety tips

Common side effects include drowsiness, dry mouth, constipation, blurred vision, and weight gain. Because doxepin has anticholinergic effects, older adults can be more sensitive—falls, confusion, and urinary problems can occur.

Watch out for interactions. Do not combine doxepin with MAO inhibitors within a 14-day window—this can be dangerous. Mixing with other sedatives, alcohol, or benzodiazepines increases drowsiness and breathing problems. Some combinations raise the risk of heart rhythm changes (QT prolongation). Tell your doctor about all meds, supplements, and herbs you take.

Before starting, healthcare providers often check blood pressure and heart health. If you have heart disease, glaucoma, severe urinary retention, or recent heart attack, mention that—doxepin may not be right or may need extra monitoring. If you’re pregnant, breastfeeding, or planning pregnancy, discuss risks vs benefits with your clinician.

Serious warning: anyone under 25 starting antidepressants should be monitored closely for worsening mood or suicidal thoughts. Families and caregivers should report behavioral changes promptly.

Thinking of buying doxepin online? Use licensed pharmacies that require a prescription, show pharmacist contact info, and have clear return and privacy policies. Avoid sites that sell without prescription or hide their address.

Questions for your doctor: Why this dose? How long will I take it? What side effects should I expect and when should I call? How do we stop it safely? Keep a short list like this before appointments to get clear, practical answers.

If you want more on dosing specifics, switching meds, or safe online pharmacies, check trusted medical sites or ask your prescriber. Doxepin can help many people, but the right support and monitoring make the difference.
