Phototoxicity from Doxycycline Doxycycline gives a very characteristic rash with redness/sunburn of the dorsal hands, fingers and nose.

Doxycycline is an oral tetracycline antibiotic commonly used in dermatology for acne and rosacea.

Acne and Renal Impairment

Doxycycline is metabolized exclusively through the hepatobiliary tract and does not require dose adjustment for chronic renal failure. Tetracycline, minocycline, cephalexin, and trimethoprim-sulfamethoxazole are all eliminated through the kidney and require dose reduction or drug substitution in patients with significant renal insufficiency.
