Practical advice

Warfarin and Vilazodone appear safe at standard doses, but remain vigilant for signs of bleeding: unusual bruising, blood in urine/stool, or prolonged bleeding from cuts. Keep your INR monitoring schedule consistent and inform your anticoagulation clinic about all medications.

Timing

SSRIs impair platelet function, which can amplify anticoagulant effects and increase bleeding risk. Take each at their normal prescribed times. Your prescriber should monitor for signs of bleeding (bruising, dark stools, prolonged cuts). INR monitoring may be more frequent if on warfarin.

Risk factors

Higher risk for: elderly patients, those with liver disease, history of GI bleeding, concurrent use of multiple blood thinners, recent surgery, vitamin K intake changes, alcohol use, or low body weight.

Symptoms to watch for

Watch for: unusual or easy bruising, blood in urine or stool, prolonged bleeding from minor cuts, frequent nosebleeds, bleeding gums, or heavy menstrual periods. Have your INR or clotting times checked more frequently when starting or stopping this combination. When to seek emergency help: Severe bleeding that does not stop, blood in vomit, sudden severe headache, vision changes, confusion, or weakness on one side of the body (possible internal bleeding or stroke).
