Benzamycin

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.

Benzamycin is part of the drug class:

• Peroxides

Benzoyl peroxide has an antibacterial effect. It also has a mild drying effect that allows excess oils and dirt to be easily washed away.

Erythromycin is an antibiotic. Erythromycin topical prevents bacteria from growing on the skin.

Benzoyl peroxide and erythromycin topical (for the skin) is a combination medicine used to treat acne.

Benzoyl peroxide and erythromycin topical may also be used for purposes not listed in this medication guide.

Apply the missed dose as soon as you remember. However, if it is almost time for the next dose, skip the dose you missed and apply only the next regularly scheduled dose.

Do not use this medicine on sunburned, windburned, dry, chapped, or irritated skin. It could make these conditions much worse. Also avoid using benzoyl peroxide and erythromycin topical on wounds or on areas of eczema. Wait until these conditions have healed before using this medicine.

Avoid using skin products that can cause irritation, such as harsh soaps, shampoos, or skin cleansers, hair coloring or permanent chemicals, hair removers or waxes, or skin products with alcohol, spices, astringents, or lime.

Avoid using other medications on the areas you treat with benzoyl peroxide and erythromycin topical unless your doctor tells you to.

Antibiotic medicines can cause diarrhea, which may be a sign of a new infection. If you have diarrhea that is watery or bloody, stop using benzoyl peroxide and erythromycin topical and call your doctor. Do not use anti-diarrhea medicine unless your doctor tells you to.

Avoid exposure to sunlight or tanning beds. This medication can make you sunburn more easily. Wear protective clothing and use sunscreen (SPF 30 or higher) when you are outdoors.

Avoid using sunscreen containing PABA on the same skin treated with benzoyl peroxide and erythromycin topical, or skin discoloration may occur.

Benzoyl peroxide can bleach hair or fabrics. Do not let this medicine come into contact with clothing, hair, or colored towels or bed linens.
