HOW DO THESE DRUGS WORK?
Benzoyl peroxide works by removing cells from the top layer of the skin surface. This action unclogs the pores so that oil (sebum) can escape. In addition, it has antibacterial action, thereby helping to clear the pores of infection by Propionibacterium acnes. Many acne preparations incorporate benzoyl peroxide because research indicates that it increases the effectiveness of some medicines. For instance, when used in combination with antibiotics, benzoyl peroxide reduces the likelihood of a patient developing resistance to the antibiotics: Noroxin, Keftab, Vantin.
WHAT ARE THE BENEFITS?
These topical medications can reduce mild to moderate acne without the risk of systemic side effects.
POTENTIAL SIDE EFFECTS
Stinging, dryness, and peeling tend to occur initially. Irritation, redness, scaly eruptions, darkening or lightening of the skin, or rash can be more serious side effects.
MAJOR CAUTIONS
Benzoyl peroxide can make the skin more sensitive to sunlight, so avoid prolonged sun exposure and tanning lights. It should not be used on sunburned, windburned, dry, chapped, or irritated skin. Research conducted on lab mice, and in some instances hamsters, indicates that benzoyl peroxide has led to the rapid development of carcinoma (skin cancer).Avoid contact with wounds, the eyes, the mouth, and mucous membranes.
MEDICAL PRECAUTIONS
If you are pregnant or lactating, you should discuss the risks of using benzoyl peroxide with your doctor.
