Paromomycin (Gabbroral) is an antibiotic in the Aminoglycoside family. It is used to a limited subset of skin and digestive tract infections.
Paromomycin is available in topical and oral formulations. Topical Paromomycin is rarely used as an acne treatment, and it is only available in some countries. Oral Paromomycin is never used as an acne treatment because this medication is not absorbed into the bloodstream from the digestive tract.
Laboratory testing has demonstrated that the acne-causing P. acnes bacteria is naturally resistant to Aminoglycoside family antibiotics, including Paromomycin. This medication is not widely available and there is little clinical research into the efficacy of Paromomycin as a treatment for acne symptoms.
