Hello and welcome to Healthcare Magic. Thanks for your query.
Tancodep is a combination medication which contains Imipramine
25mg (a sedative antidepressant) and diazepam 2mg (a benzodiazepine
sedative). Benzodiazepines as well as sedative can cause withdrawal symptoms
when stopped suddenly. Some persons can also have rebound depression or anxiety. Though Nexito is also an antidepressant, it belongs to a different class called SSRIs. Moreover, SSRI medication
can produce a side effect of temorarily increasing anxiety in the first few days (which will subside on its own within 2 weeks).
Your cardiologist may have asked you to change the antidepressant because imipramine is not ususally advised for people with cardiac problems. I would advise you to consult a psychiatrist
for a proper psychological assessment, to determine what medication you need and if the previous medication needs to be tapered down more gradually, to prevent any withdrawal effects.
Wish you all the best.
