Before taking trimipramine,
tell your doctor and pharmacist if you are allergic to trimipramine, clomipramine (Anafranil), desipramine (Norpramin), imipramine (Tofranil), or any other medications, or any of the ingredients in trimipramine capsules. Ask your doctor or pharmacist for a list of the ingredients.
tell your doctor if you are taking monoamine oxidase (MAO) inhibitors, including isocarboxazid (Marplan), linezolid (Zyvox), methylene blue, phenelzine (Nardil) selegiline (Eldepryl, Emsam, Zelapar) and tranylcypromine (Parnate) or if you have taken an MAO inhibitor during the past 14 days. Your doctor will probably tell you not to take trimipramine.
tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Be sure to mention any of the following: cimetidine (Tagamet); decongestants; guanethidine (Ismelin); ipratropium (Atrovent); medications for irritable bowel disease, motion sickness, Parkinson's disease, ulcers, or urinary problems; medications for irregular heartbeats such as quinidine (Quinidex), flecainide (Tambocor), and propafenone (Rythmol); other antidepressants; and selective serotonin reuptake inhibitors (SSRIs) such as fluoxetine (Prozac, Sarafem), paroxetine (Paxil), and sertraline (Zoloft). Tell your doctor or pharmacist if you have stopped taking fluoxetine (Prozac, Sarafem) in the past 5 weeks. Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
tell your doctor if you have recently had a heart attack. Your doctor will probably tell you not to take trimipramine.
tell your doctor if you have or have ever had an enlargement of the prostate (a male reproductive gland), difficulty urinating, thyroid disease, seizures, or heart, kidney, or liver disease.
tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking trimipramine, call your doctor.
if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking trimipramine.
you should know that trimipramine may make you drowsy. Do not drive a car or operate machinery until you know how this medication affects you.
remember that alcohol can add to the drowsiness caused by this medication.
plan to avoid unnecessary or prolonged exposure to sunlight and to wear protective clothing, sunglasses, and sunscreen. Trimipramine may make your skin sensitive to sunlight.
you should know that trimipramine may cause angle-closure glaucoma (a condition where the fluid is suddenly blocked and unable to flow out of the eye causing a quick, severe increase in eye pressure which may lead to a loss of vision). Talk to your doctor about having an eye examination before you start taking this medication. If you have nausea, eye pain, changes in vision, such as seeing colored rings around lights, and swelling or redness in or around the eye, call your doctor or get emergency medical treatment right away.
