Yes, you can go out in the sun if you are taking spironolactone. By itself, spironolactone does not make your skin more sensitive to the sun.
However, spironolactone is sometimes used in combination with other medicines. Some of these other medicines, like hydrochlorothiazide (HCTZ), may make your skin more sensitive to the sun. Be sure to check with your doctor about sun sensitivity if you take spironolactone combined with another medicine.
Regardless of the medicines you take, use caution when going out in the sun. Protect your skin from the harmful effects of the sun’s UV rays. Use sunblock, hats, and stay in the shade.
Block the rays for fun in the sun!
