Photosensitive drug reaction
Photosensitive drug reaction (pronunciation: fo-toh-sen-si-tiv drug ree-ak-shun) is a condition that occurs when certain medications cause the skin to become more sensitive to sunlight.
Etymology
The term "photosensitive" comes from the Greek words "phos" (light) and "sensitivos" (sensitive), while "drug reaction" is a term used in Pharmacology to describe the body's response to a medication.
Definition
A photosensitive drug reaction, also known as a Drug-induced photosensitivity, is a skin reaction caused by the interaction between certain types of drugs and sunlight. The reaction can cause symptoms such as redness, inflammation, and in severe cases, blistering. The severity of the reaction can vary depending on the type of drug, the dosage, and the individual's sensitivity to sunlight.
Causes
Photosensitive drug reactions are caused by certain medications that make the skin more sensitive to sunlight. These can include certain types of Antibiotics, Nonsteroidal anti-inflammatory drugs (NSAIDs), and Diuretics. When these drugs are taken, they can absorb UV light, which then leads to a skin reaction.
Symptoms
Symptoms of a photosensitive drug reaction can vary, but often include redness, itching, and swelling of the skin. In severe cases, blistering and peeling may occur. These symptoms typically occur on areas of the skin that have been exposed to sunlight.
Treatment
Treatment for a photosensitive drug reaction typically involves discontinuing the medication causing the reaction and managing the symptoms. This can include using Topical corticosteroids to reduce inflammation and applying cool compresses to soothe the skin. In some cases, a different medication may be prescribed.
Prevention
Prevention of photosensitive drug reactions primarily involves avoiding sun exposure when taking medications known to cause this reaction. This can include wearing protective clothing, using sunscreen, and avoiding sun exposure during peak hours.
