Various classes of drugs can cause photosensitivity. These include antibiotics like tetracyclines and sulfonamides, non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen, and antihistamines like promethazine. Some psychiatric medications, such as chlorpromazine, and cardiovascular drugs like amiodarone, are also known to cause photosensitivity. It's critical for healthcare providers to be aware of these drugs to manage and advise patients accordingly.
