Coumadin with antidepressants: interactions
Many adults take an antidepressant for mood, anxiety or chronic pain. The combination with Coumadin (Warfarin) is common and, for most antidepressant classes, well tolerated. A few specific combinations require attention because of additive effects or shared metabolic pathways.
Antidepressant interaction landscape
SSRIs, SNRIs, TCAs, MAOIs and atypical antidepressants each interact differently. SSRIs are the most commonly co-prescribed and usually have minor or no clinically meaningful interaction with Warfarin at 1mg, 2mg, 2.5mg, 3mg, 4mg, 5mg, 6mg, 7.5mg, 10mg. MAOIs require special caution with many medications. Tricyclics can amplify cardiovascular and sedative effects of some Cardiovascular Medications agents.
Practical guidance
According to the prescribing information for Warfarin, any change in antidepressant therapy should be reviewed alongside Coumadin dosing. Switching antidepressants — particularly to or from MAOIs — usually requires a washout period before resuming Coumadin at the standard 1mg, 2mg, 2.5mg, 3mg, 4mg, 5mg, 6mg, 7.5mg, 10mg schedule.
