By: Alere Staff
It is important to take all your medication as directed by your doctor. When on warfarin medication, sometimes taking over-the-counter medicines can have unwanted drug interactions.1
Some common over-the-counter medicines include pain relievers and cold medicines, but herbal supplements and vitamins are often overlooked. According to one study in The Journal of the American Medical Association, one in 25, or 2.2 million, older Americans are taking drug or supplement combinations that could place them at risk.2
Warfarin medication was identified as the prescription drug most likely to be associated with an increased risk of dangerous drug combinations or interactions.
