Important: How To Use This Information
This is a summary and does NOT have all possible information about this product. This information does not assure that this product is safe, effective, or appropriate for you. This information is not individual medical advice and does not substitute for the advice of your health care professional. Always ask your health care professional for complete information about this product and your specific health needs.
Antidepressant medications are used to treat a variety of conditions, including depression and other mental/mood disorders. These medications can help prevent suicidal thoughts/attempts and provide other important benefits. However, studies have shown that a small number of people (especially people younger than 25) who take antidepressants for any condition may experience worsening depression, other mental/mood symptoms, or suicidal thoughts/attempts. Therefore, it is very important to talk with the doctor about the risks and benefits of antidepressant medication (especially for people younger than 25), even if treatment is not for a mental/mood condition.
Tell the doctor right away if you notice worsening depression/other psychiatric conditions, unusual behavior changes (including possible suicidal thoughts/attempts), or other mental/mood changes (including new/worsening anxiety, panic attacks, trouble sleeping, irritability, hostile/angry feelings, impulsive actions, severe restlessness, very rapid speech). Be especially watchful for these symptoms when a new antidepressant is started or when the dose is changed.
This medication is used to treat depression. It may help improve your mood and sense of well-being and allow you to enjoy everyday life more. Trimipramine is a tricyclic antidepressant. It works by restoring the balance of certain natural substances (neurotransmitters) in the brain.
How To Use
Read the Medication Guide available from your pharmacist. Consult your doctor or pharmacist if you have any questions.
Take this medication by mouth with or without food, usually one to three times daily or as directed by your doctor. If taking this medication once daily, take it at bedtime to decrease the risk of drowsiness. Dosage is based on your medical condition and response to therapy. Your doctor may start you at a low dose and gradually increase your dose. Follow your doctor's instructions carefully.
This medication does not work right away. It may take 2 to 4 weeks before you experience the full benefits.
Use this medication regularly in order to get the most benefit from it. To help you remember, use it at the same time(s) each day.

Trimipramine may cause a condition that affects the heart rhythm (QT prolongation). QT prolongation can rarely cause serious (rarely fatal) fast/irregular heartbeat and other symptoms (such as severe dizziness, fainting) that need medical attention right away.
The risk of QT prolongation may be increased if you have certain medical conditions or are taking other drugs that may cause QT prolongation. Before using trimipramine, tell your doctor or pharmacist of all the drugs you take and if you have any of the following conditions:
- certain heart problems (heart failure, slow heartbeat, QT prolongation in the EKG)
- family history of certain heart problems (QT prolongation in the EKG, sudden cardiac death)
Low levels of potassium or magnesium in the blood may also increase your risk of QT prolongation. This risk may increase if you use certain drugs (such as diuretics/"water pills") or if you have conditions such as severe sweating, diarrhea, or vomiting. Talk to your doctor about using trimipramine safely.
This drug may make you dizzy or drowsy or blur your vision. Alcohol or marijuana (cannabis) can make you more dizzy or drowsy. Do not drive, use machinery, or do anything that needs alertness or clear vision until you can do it safely. Limit alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis).
To minimize dizziness and lightheadedness, get up slowly when rising from a seated or lying position.
Before having surgery, tell your doctor or dentist that you are taking this medication.
This medication may make you more sensitive to the sun. Limit your time in the sun. Avoid tanning booths and sunlamps. Use sunscreen and wear protective clothing when outdoors. Tell your doctor right away if you get sunburned or have skin blisters/redness.
This drug may rarely make your blood sugar rise, which can cause or worsen diabetes. If you have diabetes, check your blood sugar regularly as directed and share the results with your doctor. Tell your doctor right away if you have symptoms of high blood sugar such as increased thirst/urination. Your doctor may need to adjust your diabetes medication, exercise program, or diet.
Older adults may be more sensitive to the side effects of this drug, especially dizziness (more likely when standing up), drowsiness, confusion, constipation, trouble urinating or QT prolongation (see above). Drowsiness, dizziness, or confusion can increase the risk of falling.
Caution is advised when using this drug in children (see also the Warning section).
This medication should be used only when clearly needed during pregnancy. Infants born to mothers who have taken similar medications during pregnancy may develop trouble urinating, lethargy, shaking (tremors), and seizures. Discuss the risks and benefits with your doctor.
Since untreated mental/mood problems (such as depression) can be a serious condition, do not stop taking this medication unless directed by your doctor. If you are planning pregnancy, become pregnant, or think you may be pregnant, immediately discuss with your doctor the benefits and risks of using this medication during pregnancy.
It is unknown if this medication passes into breast milk. Consult your doctor before breast-feeding.
Drug interactions may change how your medications work or increase your risk for serious side effects. This document does not contain all possible drug interactions. Keep a list of all the products you use (including prescription/nonprescription drugs and herbal products) and share it with your doctor and pharmacist. Do not start, stop, or change the dosage of any medicines without your doctor's approval.
Some products that may interact with this drug include:
- anticholinergics (such as atropine, belladonna alkaloids)
- certain drugs for high blood pressure (such as guanadrel, guanethidine)
- drugs affecting liver enzymes that remove this medication from your body (including cimetidine, haloperidol, protease inhibitors such as fosamprenavir/ritonavir, drugs that affect heart rhythm such as flecainide/quinidine/propafenone)

- thyroid medication
Taking MAO inhibitors with this medication may cause a serious (possibly fatal) drug interaction. Do not take any MAO inhibitors (isocarboxazid, linezolid, methylene blue, moclobemide, phenelzine, procarbazine, rasagiline, safinamide, selegiline, tranylcypromine) during treatment with this medication. Some MAO inhibitors should also not be taken for two weeks before or after treatment with this medication. Ask your doctor when to start or stop taking this medication.
The risk of serotonin syndrome/toxicity increases if you are also taking other drugs that increase serotonin. Examples include street drugs such as MDMA/"ecstasy," St. John's wort, certain antidepressants (including SSRIs such as fluoxetine/paroxetine, SNRIs such as duloxetine/venlafaxine), among others. The risk of serotonin syndrome/toxicity may be more likely when you start or increase the dose of these drugs.
Many drugs besides trimipramine may affect the heart rhythm (QT prolongation in the EKG), including disopyramide, dronedarone, among others. Therefore, before using trimipramine, report all medications you are currently using to your doctor or pharmacist.
Tell your doctor or pharmacist if you are taking other products that cause drowsiness such as opioid pain or cough relievers (such as codeine, hydrocodone), alcohol, marijuana (cannabis), drugs for sleep or anxiety (such as alprazolam, lorazepam, zolpidem), muscle relaxants (such as carisoprodol, cyclobenzaprine), or antihistamines (such as cetirizine, diphenhydramine).
