Anyone planning on spending time out in the sun should practice sun safety, but especially when trying to avoid sun sensitivity reactions with medications. Here are a few ways to help protect your skin:

- Wear protective clothing—Covering your skin with clothing like long sleeved shirts, wide brimmed hats, and sunglasses may help protect your skin and eyes from the harmful effects of UV rays. Some fabrics and lenses are even designed with UV protection.
