⚠️ FDA Boxed Warning — the FDA’s strongest safety alert ▾
Important warning: doxepin and the risk of suicidal thoughts in young people. Antidepressants, including doxepin, have been shown to increase the risk of suicidal thinking and behavior in children, teenagers, and young adults (particularly those under 25). This risk appeared in short-term studies. Doxepin tablets are not approved for use in anyone under 18. All patients — especially younger adults — taking doxepin should be monitored closely for any worsening of mood, new or increased thoughts of suicide, or unusual changes in behavior. If you or someone you know notices these signs, contact a healthcare provider immediately.
📖 Doxepin: Patient Information Guide
A plain-language walkthrough of Doxepin — what it treats, how it works, how it’s taken, side effects, warnings and interactions. Tap any section to expand it.
🎯What it's used for▾
Doxepin tablets are prescribed to treat insomnia in adults — specifically when the main problem is staying asleep.
- Sleep maintenance insomnia — waking up during the night or too early and being unable to fall back asleep
⚙️How it works▾
The exact way doxepin promotes sleep isn't fully known, but the leading explanation is that it blocks the brain's H1 histamine receptor. Histamine is a chemical that helps keep you awake and alert. By blocking this receptor very strongly, doxepin essentially quiets the wake signal in your brain, helping you stay asleep longer. This is the same basic mechanism as older antihistamines that cause drowsiness — but at a much lower, targeted dose.
💊How it's taken▾
Doxepin is taken by mouth as a tablet. Your prescriber will choose the right dose and schedule for you. A few important rules to follow:
- Do not take it within 3 hours of eating — food slows how fast it works and can increase morning grogginess
- Take it only when you're ready for bed and can get a full night of sleep
- If you miss a dose, skip it — never double up the next night
- Do not stop suddenly after long-term use; your doctor will help you taper off gradually
🤒Side effects — in detail▾
Most people tolerate doxepin well at the low doses used for sleep. The most commonly reported side effects include:
- Drowsiness or sedation — sometimes carrying into the next morning
- Nausea
- Upper respiratory infection symptoms (runny nose, mild cold symptoms)
More serious reactions — such as signs of serotonin syndrome (agitation, fever, muscle twitching), thoughts of self-harm, difficulty urinating, or manic behavior — require prompt medical attention. Contact your doctor or seek emergency care if these occur.
⚠️Warnings & precautions▾
Suicidal thoughts in young adults: Like all antidepressants, doxepin carries a boxed warning about increased risk of suicidal thinking and behavior in people under 25. All patients should be monitored for mood changes, worsening symptoms, or new thoughts of self-harm — especially early in treatment.
- Serotonin syndrome: A potentially life-threatening reaction if doxepin is combined with other drugs that raise serotonin. Symptoms include agitation, rapid heart rate, fever, and muscle jerking.
- Driving and alertness: Doxepin causes sedation. Avoid driving or operating dangerous equipment until you know how it affects you.
- Mania/Bipolar risk: Doxepin can trigger a manic episode in people with bipolar disorder. Screening for bipolar history is recommended before starting.
- Angle-closure glaucoma: Doxepin should be avoided in people with untreated narrow-angle glaucoma.
🔀What it interacts with▾
Doxepin can interact with a number of medications and substances. Key ones to know:
- MAOIs (e.g., linezolid, phenelzine, selegiline, IV methylene blue) — combining these can cause dangerous, potentially fatal reactions; a 14-day washout period is required on both sides
- Other serotonergic drugs (medications that raise serotonin) — risk of serotonin syndrome increases
- Strong CYP2D6 inhibitors — can raise doxepin blood levels, increasing side effect risk; a dose adjustment may be needed
- Carbamazepine — lowers doxepin levels, possibly reducing effectiveness
- Cimetidine (OTC heartburn medication) — can roughly double doxepin levels in the blood
- Alcohol and sedating substances — amplify the drowsiness caused by doxepin
This is not a complete list of interactions. Always talk with your doctor or pharmacist before starting, stopping, or changing any medication.
📋Before taking it▾
- Allergy to doxepin or dibenzoxepines — do not take if you've had a reaction to these
- Untreated narrow-angle glaucoma — contraindicated; tell your doctor if you have glaucoma
- Severe urinary retention — contraindicated; discuss any prostate or bladder issues with your doctor
- Bipolar disorder or family history of mania — must be screened before starting
- Pregnancy — third-trimester use has been linked to newborn adaptation problems; discuss risks with your doctor
- Breastfeeding — not recommended; talk to your doctor about alternatives
- Children and teenagers — not approved for use in anyone under 18
- Older adults — should start at a lower dose and be monitored carefully before any increase
- Liver problems or tendency toward urinary retention — a lower starting dose is advised
🚑If you take too much▾
Taking too much doxepin can cause serious effects, including confusion, hallucinations, seizures, severe low blood pressure, and dangerous heart rhythm problems. In critical overdose, coma is possible. If you suspect an overdose, call Poison Control (1-800-222-1222) or go to an emergency room immediately — and bring the medication bottle with you.
📡Pharmacodynamics — effects in the body▾
Doxepin binds very strongly to the H1 histamine receptor in the brain — one of the signals that keeps you awake. By blocking this receptor, it reduces wakefulness during the night. In clinical testing, doxepin at doses used for sleep did not affect the heart's electrical activity (QT interval), which is reassuring from a cardiac safety standpoint.
🔬Pharmacokinetics — how your body processes it▾
After taking doxepin by mouth, it typically reaches peak levels in the blood around 3.5 hours when taken on an empty stomach. Eating a high-fat meal before taking it delays that peak by about 3 hours and increases overall exposure — which is why it's recommended to take it at least 3 hours after your last meal. Doxepin is broken down mainly by liver enzymes (CYP2D6 and CYP2C19), and its half-life — the time it takes your body to clear half the drug — is about 15 hours. Its main breakdown product, nordoxepin, stays in the body even longer (around 31 hours), which can contribute to morning grogginess if levels build up.
📦How to store it▾
Store at 20°C to 25°C (68°F to 77°F) , protected from light. Dispense in a tight, light resistant container.

📈 How widely Doxepin is used
A general measure of how commonly Doxepin is prescribed, based on Medicaid — one of the largest public drug programs. The figure below is prescriptions filled in Q1–Q4 2025, summed across every form and brand of the drug.
Think of this as a proxy for how widely Doxepin is used, drawn from freely available public data. Medicaid is just one program — these numbers don’t include Medicare, other government coverage, or commercial and cash-pay prescriptions, so real-world use is higher than what’s shown here.
How commonly is Doxepin prescribed? Of the 1,596 medications we measure, Doxepin ranks #233 by Medicaid prescriptions — more than 85% of them.

Shares are of the Medicaid prescriptions shown here. Product grouping follows RxNorm (the National Library of Medicine’s drug terminology), so “one product” means one strength & dosage form regardless of manufacturer. Dollar figures are gross Medicaid reimbursement before mandatory rebates — rebates (often large, especially for brand-name drugs) are confidential, so actual net cost to Medicaid is lower than shown.

📈 What people report — real-world data (FDA FAERS)
After a medicine reaches the market, patients, doctors and drugmakers can send the FDA reports of problems they think may be linked to it. Here’s what’s been reported for Doxepin — a signal of what to watch for, not proof the drug caused it.
Source: openFDA, from the FDA Adverse Event Reporting System (FAERS). These are voluntary reports — they don’t prove the drug caused the effect, and counts reflect how often something was reported, not how often it actually happens. Reports also often name the very problem the medicine is taken for — a common reason to file one is that the drug didn’t help — so for a pain reliever you may see “pain” high on the list; that points to why the report was filed, not to the drug causing the symptom. This counts every report that lists Doxepin in any role, so the total runs higher than the FDA’s official dashboard, which counts only cases where the drug is the suspect. For the authoritative figures, see the FDA FAERS Public Dashboard. Always talk to your pharmacist or doctor.

🔬 Where this comes from
Core label, product, RxNorm, safety, and utilization data on this page come from the sources identified below. AI-written, editorial, and licensed sections are labeled separately.
How we combine label and product data
HelloPharmacist combines public FDA and NLM records; we don’t author the underlying clinical facts. We identified 105 FDA-filed SPL label sets within the page’s selected clinical scope after exact ingredient or ingredient-combination matching and applicable route/form matching. The representative label is the starting point for the displayed reference monograph; the 12 largest stored in-scope SPL records, which may include that representative, are compared section by section, and the longest available version of each section is retained. Forms, routes, brands, labelers, product-listed strengths, and product-record counts are aggregated separately from ingredient-matched FDA NDC Directory records; package records listed above are associated with the linked SPL; and the normalized concept hierarchy comes from NLM RxNorm.
For canonical ingredient pages, bounded product-attributed indication and administration excerpts may be added to the AI evidence, and the generator is instructed to preserve available product, brand, route, and form qualifiers instead of treating one label as universal. Where a section is identified as AI-written, its plain-language text is generated from bounded label evidence. New draft drug pages remain in the admin review queue before first publication. Viona Pharmaceuticals Inc is the representative DailyMed label linked for verification and dates; it is not the sole source used for the page.
This is general education, not medical advice — always consult your doctor or pharmacist about your medications and any medical condition.
