You can go out in the sun while taking an angiotensin receptor blocker (ARB). But you should always protect yourself from the sun. Cover your skin and use sunscreen.
Rarely, people taking an ARB have a reaction in the sun. Sunlight can cause a skin rash, itching, or sunburn. Contact your doctor if you notice any skin changes or rashes after starting an ARB.
Block the rays for fun in the sun!
