OAC Eradication Rates Related to Clarithromycin Resistance3

Adapted from Laine et al., Am J Gastroenterol 2003.
Photosensitivity, manifested by an exaggerated sunburn reaction, has been observed in some individuals taking tetracycline. Patients apt to be exposed to direct sunlight or ultraviolet light should be advised that this reaction can occur with tetracycline drugs. Treatment should be discontinued at the first evidence of skin erythema.
