What interactions does Doxepin show?

Please note that the interactions may vary depending on the drug formulation of a drug (eg tablet, syringe, ointment).

Concomitant administration of antiarrhythmic drugs (eg quinidine, amiodarone), neuroleptics, antimalarial drugs, H1 antihistamines and antibiotics should be avoided because of the possibility of enhancing cardiac arrhythmias.

So-called irreversible MAO inhibitors should be discontinued at least 14 days before initiating therapy with doxepin. Otherwise serious side effects such as agitation, delirium, coma, over 40 ° C fever, epileptic seizures and severe blood pressure fluctuations should be expected. In hard-to-treat depression in individual cases, the additional administration of MAO inhibitors is possible. The dose of MAO inhibitors should be increased slowly by the doctor.

Other antidepressants, neuroleptics, barbiturates, analgesics, H1 antihistamines (against allergies), anticonvulsants, narcotics and alcohol result in a mutual enhancement of the central depressant effect.

Anticholinergics such as Parkinson’s disease and other tricyclic and tetracyclic antidepressants provide a mutual enhancement of anticholinergic activity.

Cimetidine (against gastric ulcers) potentiates central depressant and anticholinergic effects.

When sympathomimetics or norepinephrine are used concomitantly (also as a vasoconstrictor in local anesthesia), the sympathomimetic effect is enhanced.

In nitro-based vasodilators and antihypertensives such as beta-blockers, the hypotensive effect is enhanced.

Co-administration of guanethidine, reserpine, clonidine and guanfacine results in a reduction in hypotensive activity. With clonidine there is an additional risk of a rise in blood pressure when discontinuing the active ingredient.

At the same time taking active ingredients that reduce the potassium concentration in the blood (for example dehydrating agents), the potassium concentration in the blood continues to drop. This must be avoided.
