Medication-Induced

Some medications, particularly doxycycline, some nonsteroidal anti-inflammatory drugs, thiazides and amiodarone, can cause sun sensitivity, most often pain, redness and swelling within a few seconds or minutes of sun exposure lasting a few hours. Less often there is a longer lasting rash on exposed areas of skin. The problem generally settles down within a few days of stopping the medication though occasionally it can take up to three months to go away.
