- Author: Jeanette L Hebel, MD; Chief Editor: Dirk M Elston, MD more...
Medication Summary
The goals of pharmacotherapy are to reduce morbidity and prevent complications.
Oral photoprotectants
Class Summary
Oral photoprotectants may prevent tissue damage due to light exposure, possibly by forming an internal light screen.
Vitamin A (Lumitene)
Exact mechanism of action not completely elucidated. Patient must be carotenemic before effects are observed. More than 1 internal light screen may be responsible for effects. May provide a limited level of photoprotection. Causes yellowing of skin (eg, carotenoderma). Photoprotection increases slowly over 4-6 weeks after treatment begins. When discontinued, skin color and benefits diminish over several weeks.
