The Pharmacist’s Take By · Clinical pharmacist · Written

Imipramine is a classic tricyclic antidepressant, on the market since about 1959 and available generically, thought to boost norepinephrine, a brain chemical; it is now usually a later choice for depression, and the tablets also serve as a short-term add-on for bedwetting in children 6 and older. It is harder to tolerate than newer antidepressants; dry mouth, constipation, drowsiness and dizziness on standing are the usual complaints. Its boxed warning covers suicidal thoughts and behavior in children, teens and young adults up to 24, so watch closely for worsening mood or unusual behavior after starting. Benefit takes one to three weeks, and it should be tapered, never stopped suddenly.

Clinical pearls

  • For bedwetting, the tablet is usually given about an hour before bedtime, and its effect may fade with continued use.
  • Tell your dentist before numbing injections, since anesthetics with epinephrine and cold-medicine decongestants act more strongly with imipramine.
  • Lock it away from children; an imipramine overdose can be fatal, and children are especially sensitive.
  • Fluoxetine, sertraline and paroxetine can raise imipramine levels, and fluoxetine lingers at least five weeks after stopping.
⚠️ FDA Boxed Warning — the FDA’s strongest safety alert ▾

Antidepressants like imipramine can increase suicidal thoughts and behavior in children, teens, and young adults (up to age 24). This was seen in short-term studies. Adults over 24 did not show this increase, and adults 65 and older had a lower risk.

Depression itself raises suicide risk. Anyone starting imipramine should be watched closely for worsening depression, suicidal thoughts, or unusual changes in behavior. Families and caregivers should stay in close contact with the prescriber. Imipramine hydrochloride is not approved for use in children for depression.

Patient information guide A plain-language walkthrough of Imipramine, written from its FDA label.

What Imipramine is used for

▾

Imipramine is used for these conditions:

  • Depression: relief of symptoms (imipramine hydrochloride tablets and imipramine pamoate capsules).
  • Childhood bedwetting (enuresis): temporary add-on therapy in children 6 and older, after other causes are ruled out (imipramine hydrochloride tablets only).

How Imipramine works

▾

Imipramine is a tricyclic antidepressant. Its exact way of working isn't known. It is thought to increase norepinephrine activity by blocking its re-uptake at nerve endings.

Its effect on bedwetting is thought to be separate from its antidepressant action.

Imipramine dosage

▾

Imipramine is taken by mouth. Your prescriber starts you low and adjusts based on response and tolerance.

  • Depression: often once daily at bedtime, or in divided doses for some people.
  • Bedwetting (Imipramine Hydrochloride tablets): about an hour before bedtime. Some children may also get an earlier dose.
  • Full antidepressant benefit may take one to three weeks.
  • Don't stop suddenly after long-term use. Your prescriber will taper the dose.

Follow your prescriber and label directions.

Dosing details from the FDA-approved label

DOSAGE AND ADMINISTRATION The following recommended dosages for imipramine pamoate capsules should be modified as necessary by the clinical response and any evidence of intolerance. Initial Adult Dosage Outpatients Therapy should be initiated at 75 mg/day. Dosage may be increased to 150 mg/day which is the dose level at which optimum response is usually obtained. If necessary, dosage may be increased to 200 mg/day. Dosage higher than 75 mg/day may also be administered on a once-a-day basis after the optimum dosage and tolerance have been determined. The daily dosage may be given at bedtime. In some patients it may be necessary to employ a divided-dose schedule. As with all tricyclics, the antidepressant effect of imipramine may not be evident for one to three weeks in some patients. Hospitalized Patients Therapy should be initiated at 100 to 150 mg/day and may be increased to 200 mg/day. If there is no response after two weeks, dosage should be increased to 250 to 300 mg/day. Dosage higher than 150 mg/day may also be administered on a once-a-day basis after the optimum dosage and tolerance have been determined. The daily dosage may be given at bedtime. In some patients it may be necessary to employ a divided-dose schedule. As with all tricyclics, the antidepressant effect of imipramine may not be evident for one to three weeks in some patients. Adult Maintenance Dosage Following remission, maintenance medication may be required for a longer period of time at the lowest dose that will maintain remission after which the dosage should gradually be decreased. The usual maintenance dosage is 75 to 150 mg/day. The total daily dosage can be administered on a once-a-day basis, preferably at bedtime. In some patients it may be necessary to employ a divided-dose schedule. In cases of relapse due to premature withdrawal of the drug, the effective dosage of imipramine should be reinstituted. Adolescent and Geriatric Patients Therapy in these age groups should be initiated with Tofranil™, brand of imipramine hydrochloride tablets, at a total daily dosage of 25 to 50 mg, since imipramine pamoate capsules are not available in these strengths. Dosage may be increased according to response and tolerance, but it is generally unnecessary to exceed 100 mg/day in these patients. Imipramine pamoate capsules may be used when total daily dosage is established at 75 mg or higher.

Imipramine warnings and precautions

▾
  • Suicidality: antidepressants raise the risk of suicidal thoughts and behavior in children, teens, and young adults. Watch closely, especially early on.
  • Heart effects: imipramine can cause arrhythmias, heart block, blood pressure changes, and has been linked to heart attack and stroke.
  • Other risks: seizures, confusion, angle-closure glaucoma, liver changes, and low sodium.
  • Stopping suddenly: can cause nausea, headache, and malaise.

Imipramine interactions

▾

Imipramine can clash with many drugs.

  • MAOIs, linezolid, IV methylene blue: serotonin syndrome risk.
  • SSRIs and other CYP2D6 inhibitors: can raise imipramine levels.
  • Barbiturates and phenytoin: can lower levels.
  • Anticholinergic drugs: stronger dry mouth, constipation, and bowel blockage.
  • Decongestants and local anesthetics with epinephrine-like ingredients: avoid.
  • Blood pressure medicines: use caution.
  • Alcohol and CNS depressants: increased sedation.

Interactions listed in the FDA-approved label

From the Imipramine prescribing information (“Drug Interactions”): what the manufacturer studied or reported to the FDA.

  • Drugs that inhibit cytochrome P450 2D6 (quinidine, cimetidine, other antidepressants, phenothiazines, propafenone, flecainide): They can raise TCA plasma concentrations, and a patient stable on a TCA dose may become abruptly toxic. May require lower doses of the TCA or the other drug; an increased TCA dose may be needed when the other drug is withdrawn; monitor TCA plasma levels.
  • SSRIs (fluoxetine, sertraline, paroxetine): All inhibit P450 2D6, to varying extents, which may cause clinical problems with TCAs. Use caution when coadministering or switching classes; allow sufficient time (at least 5 weeks may be necessary) before starting a TCA after withdrawing fluoxetine.
  • Hepatic enzyme inhibitors (cimetidine, fluoxetine): Plasma concentration of imipramine may increase. Dosage adjustment of imipramine may be necessary.
  • Hepatic enzyme inducers (barbiturates, phenytoin): Plasma concentration of imipramine may decrease. Dosage adjustment of imipramine may be necessary.
  • Anticholinergic drugs (including antiparkinsonism agents): Atropine-like effects may become more pronounced (e.g., paralytic ileus). Close supervision and careful dosage adjustment required.
  • Sympathomimetic amines (e.g., epinephrine, norepinephrine; decongestants and local anesthetics containing them): Tricyclic antidepressants can potentiate the effects of catecholamines. Avoid use of such preparations.
  • Agents that lower blood pressure: Label does not state a specific effect. Caution should be exercised.
  • CNS depressant drugs: Imipramine may potentiate the effects of CNS depressant drugs.
  • Alcohol: Imipramine may enhance the CNS depressant effects of alcohol. Patients should be warned.
Read the label’s full interactions text

Drug Interactions Drugs Metabolized by P450 2D6 : The biochemical activity of the drug metabolizing isozyme cytochrome P450 2D6 (debrisoquin hydroxylase) is reduced in a subset of the Caucasian population (about 7% to 10% of Caucasians are so-called "poor metabolizers"); reliable estimates of the prevalence of reduced P450 2D6 isozyme activity among Asian, African, and other populations are not yet available. Poor metabolizers have higher than expected plasma concentrations of tricyclic antidepressants (TCAs) when given usual doses. Depending on the fraction of drug metabolized by P450 2D6, the increase in plasma concentration may be small, or quite large (8-fold increase in plasma AUC of the TCA). In addition, certain drugs inhibit the activity of this isozyme and make normal metabolizers resemble poor metabolizers. An individual who is stable on a given dose of TCA may become abruptly toxic when given one of these inhibiting drugs as concomitant therapy. The drugs that inhibit cytochrome P450 2D6 include some that are not metabolized by the enzyme (quinidine; cimetidine) and many that are substrates for P450 2D6 (many other antidepressants, phenothiazines, and the Type 1C antiarrhythmics propafenone and flecainide). While all the selective serotonin reuptake inhibitors (SSRIs), e.g., fluoxetine, sertraline, and paroxetine, inhibit P450 2D6, they may vary in the extent of inhibition. The extent to which SSRI-TCA interaction may pose clinical problems will depend on the degree of inhibition and the pharmacokinetics of the SSRI involved. Nevertheless, caution is indicated in the coadministration of TCAs with any of the SSRIs and also in switching from one class to the other. Of particular importance, sufficient time must elapse before initiating TCA treatment in a patient being withdrawn from fluoxetine, given the long half-life of the parent and active metabolite (at least 5 weeks may be necessary).

Before taking Imipramine

▾
  • Do not use it during the acute recovery period after a heart attack.
  • Do not use it if you are allergic to tricyclic antidepressants.
  • Do not combine it with MAOIs, or use within 14 days of stopping one.
  • Not approved for depression in children. For bedwetting, it is for ages 6 and older.
  • Older adults and teens typically need lower doses.

Imipramine overdose

▾

Overdose of imipramine can be fatal, and any amount in a young child is serious. Signs include dangerous heart rhythms, very low blood pressure, seizures, and coma. Get emergency help right away and contact poison control.

What Imipramine does in the body

▾

Imipramine is thought to boost norepinephrine activity by blocking its re-uptake at nerve endings. It does not work mainly by stimulating the central nervous system.

How to store Imipramine

▾

Store at 25°C (77°F); excursions permitted to 15°-30°C (59°- 86°F) . Dispense in tight container (USP) with a child-resistant closure.

Imipramine: pharmacist answers to common questions

Quick, plain-English answers to the questions patients ask most about Imipramine — the kind of thing our pharmacy team would talk through with you at the counter.

What is imipramine used for?

▾
It treats depression. The Imipramine Hydrochloride tablets are also used as temporary add-on treatment for bedwetting in kids 6 and older, once other causes are ruled out.

How soon will it work?

▾
For depression, it can take one to three weeks to feel the full effect. Keep taking it as prescribed even if you don't feel better right away, and talk to your prescriber if you have concerns.

Can I stop taking it if I feel better?

▾
Please don't stop on your own. Stopping suddenly after long-term use can cause nausea, headache, and malaise. Your prescriber will lower the dose gradually.

What side effects should I expect?

▾
Dry mouth, blurred vision, constipation, drowsiness, and dizziness are common. Call your doctor for fast or irregular heartbeat, seizures, severe confusion, eye pain, or any suicidal thoughts.

What should I avoid while taking it?

▾
Avoid alcohol, since it can add to the sleepiness. Don't take it with MAOIs. Tell me about any other antidepressants, and check before using decongestants or anything with epinephrine.

Is it safe for kids and teens?

▾
Antidepressants can raise the risk of suicidal thoughts in children, teens, and young adults, so close monitoring is key. Imipramine hydrochloride is not approved for depression in children. Keep it out of reach, since overdose is especially dangerous for young kids.

Is Imipramine available over the counter?

▾
No. Imipramine is a prescription medicine: every Imipramine product listed with the FDA is prescription only, so it is not sold over the counter. Your prescriber decides whether it is appropriate for you, and your pharmacist dispenses it.

When was Imipramine first available?

▾
The earliest FDA record we hold for Imipramine is from 1959: its first approval in Drugs@FDA or its earliest product listing in the NDC Directory, whichever is older. Many older medicines were in use before their first formal FDA approval, so this is the earliest date on record, not necessarily when Imipramine was first used.

Who makes Imipramine?

▾
14 companies currently list Imipramine products in the FDA's NDC Directory, including Lupin Pharmaceuticals, Inc., PD-Rx Pharmaceuticals, Inc., Hikma Pharmaceuticals USA Inc. That count includes repackagers and distributors as well as manufacturers (companies that sell only the raw ingredient are not counted), so fewer companies actually make it; the label on your bottle names the one that supplied yours.

Imipramine recall history

A recall is when a specific batch of a medicine is pulled from the market — usually a manufacturing issue, not a problem with the drug itself. Class I is most serious, Class III least.

The FDA’s enforcement reports list one Imipramine recall since July 2021. It is no longer listed as ongoing. A recall names specific lots from one company, so check the lot number on your own bottle rather than assuming every product is affected; your pharmacist can check whether your supply came from an affected lot.

RxCUIs identify vocabulary concepts, not individual packages or manufacturers.

💵 What Imipramine costs pharmacies (NADAC benchmark)

The national average invoice price pharmacies pay for the drug itself, from CMS's NADAC survey (data as of Sep 30, 2026). This is a supply-cost benchmark — not a retail price and not what you'd pay at the counter.

FormStrengthPharmacy acquisition benchmark
Tablet · Oral 25 mg $0.089 per tablet NDC details & price history
Tablet · Oral 50 mg $0.156 per tablet NDC details & price history
Tablet · Oral 10 mg $0.070 per tablet NDC details & price history
Capsule · Oral 75 mg $3.24 per capsule NDC details & price history
Capsule · Oral 150 mg $2.69 per capsule NDC details & price history
Capsule · Oral 100 mg $3.65 per capsule NDC details & price history
Why show this? Your out-of-pocket cost depends on insurance, pharmacy markup, and discounts — but the acquisition benchmark tells you whether the medication itself is inexpensive or costly, which strengths cost more per dose, and whether a cash-price quote is in a reasonable range. Each row links to the NDC-level record with its full price history.

How this page is built

HelloPharmacist combines public FDA and NLM records and does not author the underlying clinical facts. The plain-language sections are written with AI from the FDA-approved label text and reviewed by our pharmacy team before publication. Proficient Rx LP is the representative DailyMed label linked for verification and dates. This is general education, not medical advice: always talk to your doctor or pharmacist about your own medicines. How we build and review drug pages →
