Sun can affect medication, FDA reports
However, photosensitivity breaks down into two categories: photoallergy and phototoxicity. Photoallergy is when the skin breaks out in an allergic reaction and could happen days after the initial exposure. The more common one, phototoxicity, occurs within a few hours of the initial exposure and is an irritation of the skin.
All types of photosensitivity occur due to exposure to ultraviolet light.
The types of medicines that can cause photosensitivity are: Antifungals (flucytosine, griseofulvin, voricanozole); Antihistamines (cetirizine, diphenhydramine, loratadine, promethazine, cyproheptadine); Cholesterol lowering drugs (simvastatin, atorvastatin, lovastatin, pravastatin); Diuretics (thiazide diuretics: hydrochlorothiazide, chlorthalidone, chlorothiazide.; other diuretics: furosemide and triamterene); Non-steroidal anti-inflammatory drugs (ibuprofen, naproxen, celecoxib, piroxicam, ketoprofen); Oral contraceptives and estrogens; Phenothiazines (tranquilizers, anti-emetics: examples, chlorpromazine, fluphenazine, promethazine, thioridazine, prochloroperazine)Psoralens (methoxsalen, trioxsalen)Retinoids (acitretin, isotretinoin); Sulfonamides (acetazolamide, sulfadiazine, sulfamethizole, sulfamethoxazole, sulfapyridine, sulfasalazine, sulfasoxazole); Sulfonylureas for type 2 diabetes (glipizide, glyburide); and Alpha-hydroxy acids in cosmetics.
