Antidepressant interaction landscape

SSRIs are the most commonly co-prescribed and usually have minor or no clinically meaningful interaction with Valacyclovir at 500mg, 1000mg. MAOIs require special caution with many medications. Tricyclics can amplify cardiovascular and sedative effects of some Nucleoside antiviral prodrug agents.

Switching antidepressants — particularly to or from MAOIs — usually requires a washout period before resuming Valacyclovir at the standard 500mg, 1000mg schedule.
