I'm on warfarin and have a cold coming on. current meds i have at home for colds are lingtagon, corenza c, acc 200 and andolex throat spray. can i use any of these?

Drug interactions: There's probably no problem, but you can check yourself for these and any other drugs that might interact with warfarin. Google "drug interaction checker" to find several websites where you can enter any combination of drugs to see if they are safe and effective together.

Warfarin + a cold: By searching "Medication Interactions" you will get a list of sites into which you can put your medications to see if there are any interactions. But as warfarin levels require exquisitely controlled levels, the best thing you can do is put your question to the practitioner that knows you best, your Cardiologist.
