The use of antibiotic agents may be associated with the overgrowth of antibiotic-resistant organisms. If this occurs, administration of this drug should be discontinued and appropriate measures taken.
Information for patients
Erythromycin Topical Solution is for external use only and should be kept away from the eyes, nose, mouth and other mucous membranes. Concomitant topical acne therapy should be used with caution because a cumulative irritant effect may occur, especially the use of peeling, desquamating or abrasive agents.
Carcinogenesis, Mutagenesis, Impairment of Fertility
Long-term animal studies to evaluate carcinogenic potential, mutagenicity or the effect on fertility of erythromycin have not been performed.
Pregnancy Category C. Animal reproduction studies have not been conducted with erythromycin. It is also not known whether erythromycin can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Erythromycin should be given to a pregnant woman only if clearly needed.
Adverse conditions reported with the use of erythromycin topical solutions include dryness, tenderness, pruritus, desquamation, erythema, oiliness, and burning sensation. Irritation of the eyes has also been reported. A case of generalized urticarial reaction, possibly related to the drug, which required the use of systemic steroid therapy, has been reported.
