Do not go out in the sun after taking these medications
After some patients take certain medications, their skin may turn red, itchy, and hot upon exposure to sunlight, and may even experience a burning sensation, blisters, or sores. This condition, similar to solar dermatitis, is known as photosensitive drug eruption.
Medications commonly known to cause photosensitive drug eruptions include quinolone antibiotics, sulfonamide antibiotics, ibuprofen, hydrochlorothiazide, and chlorpromazine. After taking these drugs, exposure to a certain amount of sunlight can cause the otherwise harmless medication to be converted into a substance toxic to cells, damaging or killing skin cells and thereby causing a photosensitive drug eruption.
Therefore, avoid sun exposure after taking the aforementioned medications. When going outdoors, pay special attention to skin protection by using a sun umbrella and applying sunscreen. If a photosensitive drug eruption occurs, discontinue the medication that is causing the phototoxic reaction immediately. You can apply a cold compress to the swollen and red areas and consult a dermatologist.
