What the FDA labels say
From the Imipramine (Imipramine Hydrochloride) label · effective 2026-07-06
Avoid the use of preparations, such as decongestants and local anesthetics, that contain any sympathomimetic amine (e.g., epinephrine, norepinephrine), since it has been reported that tricyclic antidepressants can potentiate the effects of catecholamines.

• Monoamine oxidase inhibitors and tricyclic antidepressants: Use with extreme caution.
Monoamine Oxidase Inhibitors and Tricyclic Antidepressants SEREVENT DISKUS should be administered with extreme caution to patients being treated with monoamine oxidase inhibitors or tricyclic antidepressants, or within 2 weeks of discontinuation of such agents, because the action of salmeterol on the vascular system may be potentiated by these agents.
