Common side effects when taken by mouth include loss of appetite, vomiting, abdominal pain, and diarrhea. When applied to the skin side effects include itchiness, redness, and blisters. When given by injection there may be fever, liver problems, or hearing loss. Use during breastfeeding appears to be safe. Paromomycin is in the aminoglycoside family of medications and causes microbe death by stopping the creation of bacterial proteins.

Paromomycin was discovered in the 1950s from a type of streptomyces and came into medical use in 1960. It is on the World Health Organization's List of Essential Medicines. Paromomycin is available as a generic medication.
