Precautions Against Drinking Alcohol While Taking Blood ThinnersYou should abstain from alcohol while taking anticoagulant blood thinners such as Coumadin (warfarin) as the blood-thinning effects of alcohol can interact with those of the prescribed drugs. It will be more difficult for your healthcare providers to determine the correct dosage for the prescribed blood thinner if you also drink alcohol. As you will be placed on blood thinners to prevent a significant health threat, such as a deep venous thrombosis, it's best not to take the risk and have an alcoholic beverage.Learn More
Don't Substitute Alcohol for Prescription Blood Thinners
Contrasting Effects of Alcohol on CoagulationSome studies have shown that moderate drinkers tend to have lower rates of heart disease, but higher rates of bleeding-type strokes than abstainers. However, some researchers believe that the ability of moderate drinking to make blood platelets less "sticky" may mediate the negative effects of moderate drinking.
"The contrasting effects of alcohol are similar to the effects of blood thinners like aspirin, which clearly prevent heart attacks but at the expense of some additional bleeding strokes," said Kenneth J. Mukamal, corresponding author for a study on effects of moderate drinking on blood coagulation. "Acting as a blood thinner makes sense, because heart attacks are caused by blood clots that form in clogged arteries, and blood thinners can hasten bleeding from injured arteries. Based on these findings, we speculated that moderate drinking would also act as a blood thinner."
No Reason to Start Drinking"Our findings add to a large body of evidence showing that moderate drinking has effects on blood coagulation, which may have both good and bad effects, but now identify a new avenue by which this effect may occur," said Mukamal.
