Some medications increase the effects of the sun on a person's body. People with lupus taking these drugs including tetracycline antibiotics and many others may also very occasionally develop "phototoxic" reactions. These will lead to easy sun burning, so if you are taking these "photosensitizing" medications, you will need extra protection against sunlight. Ask your doctor or pharmacist if any of your current or new medications might make you extra-sensitive to the sun.
