Concerns related to adverse effects:
• Bleaching effects: May bleach hair or colored fabric.
• Skin irritation: Discontinue use if severe skin irritation or redness occurs.
• Superinfection: Prolonged use may result in fungal or bacterial superinfection, including C. difficile-associated diarrhea (CDAD) and pseudomembranous colitis; CDAD has been observed >2 months postantibiotic treatment. Stop the drug if significant diarrhea occurs.
Concurrent drug therapy issues:
• Sulfone products: Concomitant use of benzoyl peroxide with sulfone products (eg, dapsone, sulfacetamide) may cause temporary discoloration (yellow/orange) of facial hair and skin. Application of products at separate times during the day or washing off benzoyl peroxide prior to application of other products may avoid skin discoloration (Dubina 2009).
• Topical acne products: Use concomitant topical acne therapy with caution; cumulative irritancy may occur.
• Appropriate use: For external use only; avoid contact with mucous membranes and eyes.
Pregnancy Risk Factor
Animal reproduction studies have not been conducted with this combination. Refer to individual monographs.
• Discuss specific use of drug and side effects with patient as it relates to treatment. (HCAHPS: During this hospital stay, were you given any medicine that you had not taken before? Before giving you any new medicine, how often did hospital staff tell you what the medicine was for? How often did hospital staff describe possible side effects in a way you could understand?)
• Patient may experience dry skin. Have patient report immediately to prescriber severe skin irritation or signs of Clostridium difficile (C. diff)-associated diarrhea (abdominal pain or cramps, severe diarrhea or watery stools, or bloody stools) (HCAHPS).
• Educate patient about signs of a significant reaction (eg, wheezing; chest tightness; fever; itching; bad cough; blue skin color; seizures; or swelling of face, lips, tongue, or throat). Note: This is not a comprehensive list of all side effects. Patient should consult prescriber for additional questions.
