Sun sensitivity (photosensitivity) is an inflammation of the skin induced by the combination of medications or substances and sunlight. The effect on the skin is redness, which looks similar to a sunburn. Generally, these reactions are either phototoxic or photoallergic. Phototoxic drugs are more common than photoallergic drugs.
Symptoms of phototoxic reactions are a burning and stinging sensation and then redness. Symptoms of photoallergic reactions are itching, redness, swelling, and blisters of the affected area.
Treatment generally is discontinuation of the medication and topical application of creams. Read more: Sun-Sensitive Drugs (Photosensitivity to Drugs) Article
