Hi @patrizio, I take Eliquis (apixaban) 5 mg every morning and evening for a DVT I had about 4 months ago. I usually drink a protein shake every day in the late morning. I wasn't aware of any problems drinking a protein shake if you are on apixaban. I did find some information on a pharmacist site on the topic.

--- Can You Drink Ensure Or Boost While Taking Eliquis?: https://hellopharmacist.com/questions/can-you-drink-ensure-or-boost-while-taking-eliquis

The article mentions Boost and Ensure but I like ones that are lower in calories, sugar and carbs like Premier Protein. My favorite is their Cafe Latte which has 30g protein, 5g Tot Carbs, and 1g sugar.
