About Ery

What is this medication? Ery is a prescription antibiotic medication primarily used for the topical treatment of acne vulgaris. It contains the active ingredient erythromycin, which belongs to a group of medicines known as macrolide antibiotics. This medication works by inhibiting the growth of bacteria that contribute to the development of acne, such as Cutibacterium acnes. By reducing the number of bacteria on the skin and lowering inflammation, it helps to clear existing pimples and prevent new breakouts from forming. This medication is typically available as a topical solution or saturated pads that are applied directly to the affected areas of the skin. It is often prescribed as part of a broader skin care regimen and may be used in combination with other acne treatments to improve overall results. While generally well-tolerated, some users may experience mild side effects such as skin dryness, redness, or a slight stinging sensation. It is important to follow the specific instructions provided by a healthcare professional to ensure the medication is used safely and effectively.

Prescribing information

From the FDA-approved label for Ery. Official source: DailyMed (NLM) · Label effective Oct 11, 2024

Indications and usage

INDICATIONS AND USAGE Erythromycin Topical Solution USP, 2% is indicated for the topical treatment of acne vulgaris.

Dosage and administration

DOSAGE AND ADMINISTRATION Erythromycin Topical Solution USP, 2% should be applied over the affected areas twice a day (morning and evening) after the skin is thoroughly washed with warm water and soap and patted dry. Acne lesions on the face, neck, shoulders, chest, and back may be treated in this manner. This medication should be applied with applicator top. If fingertips are used, wash hands after application. Drying and peeling may be controlled by reducing the frequency of applications.

Contraindications

CONTRAINDICATIONS Erythromycin Topical Solution USP, 2% is contraindicated in those individuals who have shown hypersensitivity to any of its components.

Warnings

WARNINGS Pseudomembranous colitis has been reported with nearly all antibacterial agents, including erythromycin, and may range in severity from mild to life-threatening. Therefore, it is important to consider this diagnosis in patients who present with diarrhea subsequent to the administration of antibacterial agents. Treatment with antibacterial agents alters the normal flora of the colon and may permit overgrowth of clostridia. Studies indicate that a toxin produced by Clostridium difficile is one primary cause of “antibiotic-associated colitis”. After the diagnosis of pseudomembranous colitis has been established, therapeutic measures should be initiated. Mild cases of pseudomembranous colitis usually respond to drug discontinuation alone. In moderate to severe cases, consideration should be given to management with fluids and electrolytes, protein supplementation and treatment with an antibacterial drug clinically effective against C. difficile colitis.

Adverse reactions

ADVERSE REACTIONS The following local adverse reactions have been reported occasionally: peeling, dryness, itching, erythema, and oiliness. Irritation of the eyes and tenderness of the skin have also been reported with topical use of erythromycin. Generalized urticarial reactions possibly related to the use of erythromycin, which required systemic steroid therapy have been reported.

Use in pregnancy

Pregnancy: Teratogenic Effects: Pregnancy Category B - There was no evidence of teratogenicity or any other adverse effect on reproduction in female rats fed erythromycin base (up to 0.25% of diet) prior to and during mating, during gestation and through weaning of two successive litters. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used in pregnancy only if clearly needed. Erythromycin has been reported to cross the placental barrier in humans, but fetal plasma levels are generally low.
