Before taking imipramine,
tell your doctor and pharmacist if you are allergic to imipramine, any other medications, or any of the ingredients in imipramine tablets or capsules. Ask your doctor or pharmacist for a list of the ingredients.
tell your doctor if you are taking a monoamine oxidase (MAO) inhibitor such as isocarboxazid (Marplan), linezolid (Zyvox), methylene blue, phenelzine (Nardil), selegiline (Eldepryl, Emsam, Zelapar), and tranylcypromine (Parnate), or if you have stopped taking an MAO inhibitor within the past 14 days. Your doctor will probably tell you not to take imipramine. If you stop taking imipramine, you should wait at least 14 days before you start to take an MAO inhibitor.
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: anticoagulants (blood thinners) such as warfarin (Coumadin, Jantoven); antihistamines; cimetidine (Tagamet); flecainide (Tambocor); levodopa (Sinemet, Larodopa); lithium (Eskalith, Lithobid); medication for high blood pressure, mental illness, nausea, seizures, Parkinson's disease, asthma, colds, or allergies; methylphenidate (Ritalin); muscle relaxants; propafenone (Rhythmol); quinidine; sedatives; selective serotonin reuptake inhibitors (SSRIs) such as citalopram (Celexa), escitalopram (Lexapro), fluoxetine (Prozac, Sarafem), fluvoxamine (Luvox), paroxetine (Paxil), and sertraline (Zoloft); sleeping pills; thyroid medications; and tranquilizers. Your doctor may need to change the doses of your medications or monitor you carefully for side effects. Your doctor may tell you not to take imipramine if you have taken fluoxetine in the past 5 weeks.
tell your doctor if you have recently had a heart attack. Your doctor may tell you not to take imipramine.
tell your doctor if you are being treated with electroshock therapy (procedure in which small electric shocks are administered to the brain to treat certain mental illnesses), and if you have or have ever had an enlarged prostate (a male reproductive gland), difficulty urinating, seizures, an overactive thyroid gland, or liver, kidney, or heart disease.
tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking imipramine, call your doctor.
if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking imipramine.
you should know that this medication 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.
tell your doctor if you use tobacco products. Cigarette smoking may decrease the effectiveness of this medication.
plan to avoid unnecessary or prolonged exposure to sunlight and to wear protective clothing, sunglasses, and sunscreen. Imipramine may make your skin sensitive to sunlight.
you should know that imipramine 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.
