What is doxepin HCl used for?
Standard-dose doxepin capsules and oral solution (10-150 mg) are FDA-approved to treat depression and anxiety, including depression or anxiety associated with alcoholism or physical illness. Very low-dose tablets (3 mg and 6 mg, brand Silenor) are approved for insomnia in people who have trouble staying asleep, and a 5% cream form is approved for short-term relief of itching in certain skin conditions.
Is doxepin a controlled substance or addictive?
No. Doxepin is not a controlled substance and is not considered habit-forming or addictive in the way that some other sleep medicines are. Even so, you should not stop it abruptly without talking to your prescriber, because stopping suddenly can cause withdrawal-like symptoms. Take it only as directed.
How long does it take for doxepin to work for sleep?
When used at low doses for sleep, doxepin is generally taken shortly before bedtime and can help within the same night, since it works quickly to promote sleepiness. When used at higher doses for depression or anxiety, the full mood benefit usually takes several weeks. Follow the timing your prescriber recommends.
What are the most common side effects of doxepin?
The most common side effects include dry mouth, constipation, blurred vision, drowsiness or next-day grogginess, and feeling lightheaded when standing up. Older adults may be more prone to falls and confusion. Tell your prescriber if side effects are bothersome, and seek help right away for a fast or irregular heartbeat.
Can you take doxepin every night for insomnia?
The low-dose tablet approved for insomnia is intended to be taken nightly as directed by your prescriber, and it is not limited to short-term use the way some sleep aids are. How long you should stay on it depends on your situation, so review your ongoing need with your prescriber and do not change your dose on your own.

Looking for a doxepin HCl coupon?

Rx.com checks doxepin prices across more than 60,000 pharmacies so you can see today's lowest cash price near you. Enter your ZIP above to see the current price and print or text a free discount coupon.

What is doxepin HCl and how does it work?

Doxepin hydrochloride is a tricyclic antidepressant (TCA) in the dibenzoxepin family. In its standard oral capsule and oral solution strengths (10-150 mg), it is FDA-approved to treat depression and/or anxiety, including depression or anxiety linked to alcoholism, organic disease, and psychotic depressive disorders. At very low doses it works mainly by blocking the histamine H1 receptor, which is why the low-dose 3 mg and 6 mg tablets (brand Silenor) are approved specifically for insomnia marked by trouble staying asleep. A topical 5% cream form is separately approved for short-term relief of itching in certain skin conditions.

Doxepin is available as an FDA-approved generic and is not a controlled substance. Because the same molecule is used at very different doses for very different purposes, it is important to take exactly the strength and form your prescriber ordered.

Doxepin cost without insurance and how to save

Generic doxepin is one of the older, lower-cost prescription medicines, so most people pay a modest cash price even without insurance. The catch is that pharmacies set their own cash prices, and two stores in the same town can charge noticeably different amounts for the identical prescription - so it pays to compare before you fill. A Rx.com discount coupon is free to use and often beats a standard cash price; it works whether or not you have insurance, though you cannot combine it with your insurance on the same purchase.

There is no manufacturer copay savings card for generic doxepin. The low-dose brand Silenor has its own official website (silenor.com) where any current offer terms are posted; those terms vary and can change. To find the best price on generic doxepin near you, enter your ZIP above to see today's price across local and mail-order pharmacies.

Doxepin alternatives and related medications

Doxepin belongs to the same older class as other tricyclics your prescriber may consider. If you are comparing options, related medicines include:

  • Amitriptyline - another tricyclic used for depression and often prescribed for related conditions.
  • Nortriptyline - a tricyclic sometimes chosen for a somewhat different side-effect profile.
  • Silenor - the low-dose (3 mg/6 mg) doxepin tablet approved for sleep-maintenance insomnia.
  • Trazodone - a different antidepressant frequently used to help with sleep.
  • Mirtazapine - an antidepressant that can also cause drowsiness.

These are not interchangeable, and only your prescriber can decide which fits your situation. Whichever one you are prescribed, you can compare its price on Rx.com. This is general information, not medical advice.

Doxepin safety and key warnings

Doxepin carries a boxed warning that antidepressants can increase the risk of suicidal thoughts and behavior in children, adolescents, and young adults under 25; it is not approved for use in children. Watch for new or worsening mood changes, especially early in treatment or after a dose change, and contact your prescriber right away. Doxepin must not be used with, or within 14 days of, an MAO inhibitor, and it should be avoided in people with untreated narrow-angle glaucoma or urinary retention.

Common effects reflect the drug's anticholinergic and sedating nature: dry mouth, constipation, blurred vision, next-day drowsiness, and lightheadedness on standing. Older adults are more sensitive to falls and confusion (doxepin is on the Beers list), and an overdose can be dangerous to the heart. Avoid alcohol and other sedating medicines while taking it. Always follow your prescriber's instructions and ask your pharmacist about interactions - this is not medical advice.
