You can go out in the sun while taking an angiotensin-converting enzyme (ACE) inhibitor. But you should always protect yourself from the sun. Cover your skin and use sunscreen.
Rarely, people taking an ACE inhibitor 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 ACE inhibitor.
Block the rays for fun in the sun!
