Panoxyl (Benzoyl Peroxide)

Panoxyl is a topical antibacterial and keratolytic used in the management of acne‑related conditions.

• Acne vulgaris: reduces inflammatory lesions and prevents new comedone formation.
• Mild to moderate papulopustular acne: helps clear existing pustules and limits recurrence.
• Preventive acne care: maintains clearer skin by limiting bacterial colonisation.

• Benzoyl peroxide releases oxygen free radicals that oxidise bacterial proteins, decreasing Propionibacterium acnes populations, while its keratolytic action promotes exfoliation of follicular epithelium, facilitating comedone extrusion and reducing pore blockage.

Adverse reactions are generally mild to moderate and depend on skin sensitivity.

Common Side Effects

• Skin irritation: redness, burning, or stinging at the application site.
• Dryness: flaking or peeling of the treated area.
• Contact dermatitis: mild allergic response causing itching.
• Increased photosensitivity: heightened sunburn risk.

Serious or Rare Side Effects

• Severe allergic reaction: swelling, hives, or difficulty breathing.
• Contact urticaria: localized swelling with intense itching.
• Post‑inflammatory hyperpigmentation: darkening of skin after inflammation resolves.
• Widespread dermatitis: extensive rash beyond the treated area.

When using Panoxyl, follow these safety measures:

• Patch test: apply a small amount to a limited skin area before full use.
• Sun protection: use sunscreen and limit UV exposure while treating.
• Moisturize: apply a non‑comedogenic moisturizer to reduce dryness.
• Avoid ocular contact: keep product away from eyes, mouth and mucous membranes.
• Discontinue if severe irritation occurs: seek medical advice if symptoms persist.
• Store at ambient temperature: keep in original container, protect from moisture and direct sunlight.

Benzoyl peroxide may interact with other topical agents and systemic medications.

Major Interactions (Avoid)

• Retinoids (topical): concurrent use can markedly increase skin irritation.
• Antifungal creams (e.g., clotrimazole): may reduce efficacy of both products.

Moderate Interactions (Monitor Closely)

• Salicylic acid preparations: combined use may cause excessive dryness.
• Cosmetic products with alcohol or fragrance: can heighten irritation risk.
• Systemic antibiotics (e.g., tetracyclines): no direct pharmacokinetic interaction, but combined acne therapy should be monitored.
