Some products that may interact with this drug include: anticholinergics (e.g., atropine, belladonna alkaloids, scopolamine, drugs for Parkinson's disease such as benztropine), certain drugs for high blood pressure (e.g., clonidine, guanadrel, guanethidine, reserpine), digoxin, disopyramide, thyroid supplements, valproic acid.
Taking MAO inhibitors with this medication may cause a serious (possibly fatal) drug interaction. Avoid taking MAO inhibitors (isocarboxazid, linezolid, methylene blue, moclobemide, phenelzine, procarbazine, rasagiline, selegiline, tranylcypromine) during treatment with this medication. Most MAO inhibitors should also not be taken for two weeks before and 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.
Other medications can affect the removal of imipramine pamoate from your body, which may affect how imipramine pamoate works. Examples include alcohol, barbiturates (such as phenobarbital), cimetidine, cisapride, haloperidol, certain drugs for heart rhythm (such as flecainide, propafenone), halofantrine, certain HIV protease inhibitors (such as fosamprenavir), phenothiazines (such as thioridazine), pimozide, certain anti-seizure drugs (such as carbamazepine, phenytoin), terbinafine, trazodone, among others.
Cigarette smoking decreases blood levels of this medication. Tell your doctor if you smoke or if you have recently stopped smoking.
Many drugs besides imipramine pamoate may affect the heart rhythm (QT prolongation), including amiodarone, dofetilide, pimozide, procainamide, quinidine, sotalol, macrolide antibiotics (such as erythromycin), sparfloxacin, among others. Therefore, before using imipramine pamoate, report all medications you are currently using to your doctor or pharmacist.
Also report the use of drugs which might increase seizure risk (decrease seizure threshold) when combined with this medication such as isoniazid (INH), theophylline, and tramadol, among others. Consult your doctor or pharmacist for details.
Tell your doctor or pharmacist if you also take drugs that cause drowsiness such as certain antihistamines (e.g., diphenhydramine), anti-anxiety drugs (e.g., diazepam), anti-seizure drugs (e.g., levetiracetam), drugs for motion sickness (e.g., meclizine).
Check the labels on all your medicines (e.g., cough-and-cold products) because they may contain drowsiness-containing ingredients or decongestants that could increase your heart rate or blood pressure. Ask your pharmacist about the safe use of those products.
