Why do I have to stay out of the sun if I take sulfa antibiotics?
Certain medications, including sulfa antibiotics, can cause photosensitivity - being especially
sensitive to the sun's burning rays (more so than you normally are). Even brief exposure to the
sun or using a tanning booth or sunlamp can cause a person to experience a skin rash, itching,
redness, discolored skin - even a severe sunburn.
While you are taking a sulfa medication, be sure to avoid direct sunlight, especially between 10 a.m. and 3 p.m., when the sun's rays are strongest. Wear clothing and accessories to protect your skin: long-sleeved shirts and pants, and sunglasses and a wide-brimmed hat.
Apply a sunscreen with a sun protection factor (SPF) of 15 or more. Use a lip balm with SPF 15, too.
