Most of us know to avoid alcohol or certain foods that can interfere with some prescription medications. Not everyone knows that exposure to direct sunlight can also cause certain reactions.

This reaction is called photosensitivity and during the summer, when people are eager to soak up the sun’s rays, the chance of photosensitivity reactions can increase.

Experts say there are hundreds of medications which can affect photosensitivity.

These medicines include some diuretics, antibiotics, antihistamines, anti-arrhythmics, antiseizure medicines, acne medications, and antidepressants. Most of the photo reactions are caused by the ultraviolet (UV) A and UVB rays and usually present as an allergy. For those on medication that can cause photosensitivity, it’s important to take preventive measures.”

Some of signs of photosensitivity to look for are: itchy red rash on the skin that gets exposed to the sun; tiny bumps that may become raised patches; scaling; crusting; or blisters.

To help prevent sun sensitivity wear sunscreen SPF 30 or more as it provides UVA and UVB protection. Apply 15-30 minutes before sun exposure and repeatedly throughout the day. This is even more important on boat trips as the suns rays reflect off from the water increasing exposure. Wear a hat with a wide rimmed base and do not stay out in the sun for long periods, even on cloudy days.
