Some products that may interact with this drug include: arbutamine, thyroid supplements, anticholinergic drugs (such as benztropine, belladonna alkaloids), central-acting drugs to treat high blood pressure (such as clonidine, guanabenz, reserpine).
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.
Other medications can affect the removal of doxepin from your body, thereby affecting how doxepin works. These drugs include cimetidine, St. John's Wort, terbinafine, drugs to treat irregular heart rate (such as quinidine/propafenone/flecainide), antidepressants (such as SSRIs including paroxetine/fluoxetine/fluvoxamine). This is not a complete list.
Many drugs besides doxepin may affect the heart rhythm (QT prolongation in the EKG), including amiodarone, cisapride, dofetilide, pimozide, procainamide, quinidine, sotalol, macrolide antibiotics (such as erythromycin), among others. Therefore, before using doxepin, 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, including alcohol, antihistamines (such as cetirizine, diphenhydramine), drugs for sleep or anxiety (such as alprazolam, diazepam, zolpidem), muscle relaxants, and narcotic pain relievers (such as codeine).
Check the labels on all your medicines (such as allergy or cough-and-cold products) because they may contain decongestants or ingredients that cause drowsiness. Ask your pharmacist about using those products safely.
Also report the use of drugs which might increase seizure risk when combined with doxepin, including isoniazid (INH), phenothiazines (such as thioridazine), theophylline, or tricyclic antidepressants (such as nortriptyline), among others. Consult your doctor or pharmacist for details.
