Overview
Erythromycin benzoyl peroxide is the generic name for a combination product that’s used to treat acne, according to Medicine Net. Available by prescription only, the product combines the antibiotic erythromycin with the antibacterial oxidizing agent known as benzoyl peroxide. While each of the ingredients is available separately for acne treatment, the erythromycin benzoyl peroxide gel provides a convenient one-step approach to eliminating acne blemishes.
Effects
According to the American Academy of Dermatology, acne is caused by four factors: an overabundance of oil, clogged pores, bacteria and inflammation. The acne cycle starts when extra oil blocks the pores leading to the surface of your skin. Bacteria grow in the oil and irritate your tissues, creating acne lesions. Erythromycin and benzoyl peroxide work together to penetrate the blocked oil plug, kill bacteria and promote the growth of healthy new skin, according to Medicine Net.
Correct Use
Before using erythromycin benzoyl peroxide gel, gently wash your face with soap and water, rinse well and pat it dry, according to Perrigo, a company that manufactures an erythromycin benzoyl peroxide product. The gel is typically applied twice a day, once in the morning and again at night, or as otherwise instructed by your doctor.
Side Effects
Perrigo reports that only 3 percent of the people who used erythromycin benzoyl peroxide gel during clinical trials developed adverse reactions to the product. These side effects included skin irritation that showed up as dryness, hives, redness, itching, warmth, stinging and burning of the treated skin.
Tips
To limit the skin irritation from erythromycin benzoyl peroxide, Perrigo says you shouldn’t use other topical acne medications on treated skin areas. Since benzoyl peroxide is a bleaching agent, it can be harmful to mucous membranes like those in your eyes, nose and mouth. It can also bleach your hair and take the color out of fabrics like clothing and bedding.
Warnings
Since products containing erythromycin and benzoyl peroxide increase your sensitivity to the sun, Medicine Net cautions against excess sun exposure while you’re using the gel. If you do need to be in the sun, apply sunscreen over your acne.
Results
Because erythromycin benzoyl peroxide can initially irritate the skin, your acne may get worse before it gets better. However, according to Medicine Net, expect to see improvement in your acne symptoms within four to six weeks. Let your doctor know if your skin irritation persists or worsens.
