You can go out in the sun while taking amlodipine but always protect your skin from the sun. Cover your skin and wear sunscreen.
Rarely, people taking amlodipine have had a skin reaction to the sun called telangiectasia. This rash is sometimes called spider veins because red lines form on the skin in a web pattern. Tell your doctor if you notice skin changes after starting amlodipine.
Block the rays for fun in the sun!
