Composition of Zinderm Bn Gel

Zinderm Bn Gel contains Benzoyl Peroxide 2.5% w/w + Nadifloxacin 1% w/w (topical gel). It belongs to the Topical antibiotic (fluoroquinolone) + Keratolytic/antibacterial (benzoyl peroxide) class of medicines.

Uses of Zinderm Bn Gel

  • Treatment of acne vulgaris (pimples)
  • especially inflammatory acne with bacterial involvement; helps reduce comedones and acne-associated redness and swelling.

Key benefits

  • Reduces acne-causing bacteria
  • Decreases inflammation and redness
  • Unclogs pores and reduces blackheads/whiteheads
  • Helps prevent new pimples
  • Improves overall acne lesions

How Zinderm Bn Gel works

Nadifloxacin is a topical fluoroquinolone antibiotic that inhibits bacterial DNA gyrase/topoisomerase IV, reducing acne-causing bacteria and inflammation. Benzoyl peroxide releases active oxygen and has antibacterial and keratolytic effects, helping unclog pores and reduce new lesion formation.

How to take Zinderm Bn Gel

For external use only. Clean and dry the affected area, then apply a thin layer to acne-affected skin once daily or as directed by a doctor; may be increased to twice daily if tolerated. Avoid eyes, lips, inside nose and broken/irritated skin; wash hands after application and use moisturizer/sunscreen if dryness occurs.

Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.

Missed dose and overdose

If you miss a dose

Apply it as soon as you remember. If it is nearly time for the next application, skip the missed one — applying extra does not make up for it.

If you take too much

An overdose of this medicine can cause severe irritation when far too much cream is applied; an oral retinoid taken in excess can cause headache, vomiting and liver injury. It is unlikely from skin use. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.

Side effects of Zinderm Bn Gel

Most side effects of Zinderm Bn are mild and settle as the body adjusts. Reported side effects include:

  • Burning or stinging
  • dryness
  • peeling
  • redness
  • itching
  • irritation
  • photosensitivity

Stop the medicine and seek help immediately for a rash, swelling of the face or lips, wheezing or difficulty breathing. Tell your doctor about any side effect that persists or worries you.

Warnings and precautions

External use only. May cause skin irritation; start with once-daily use and reduce frequency if excessive dryness/redness occurs. Avoid contact with eyes/mucosa; rinse with water if contact occurs. Benzoyl peroxide may bleach hair/fabrics. Use sunscreen and limit sun/UV exposure. Stop and seek medical advice if severe irritation, swelling or allergic reaction occurs. Use in children, pregnancy or breastfeeding only on medical advice; avoid applying on large areas or near nipple during breastfeeding.

Do not take Zinderm Bn if

Not for anyone with a known allergy to this medicine or to any ingredient in the pack. Oral retinoids are absolutely contraindicated in pregnancy and in anyone who might become pregnant without a pregnancy prevention programme. Topical retinoids are avoided in pregnancy. Not for use in or around the eyes.

Interactions with other medicines

Avoid using simultaneously on same area with other topical irritants/keratolytics (retinoids like tretinoin/adapalene, salicylic acid, sulfur/resorcinol, astringents/alcohol-based products) unless advised; may increase irritation. If using topical retinoid, consider alternate timing (e.g., retinoid at night and this in morning) as directed.

How to store Zinderm Bn Gel

Store below 25°C in a cool, dry place away from direct light and heat. Keep cap tightly closed. Keep out of reach of children.

Expert advice for Zinderm Bn Gel

Apply retinoids at night to clean, dry skin, and moisturise afterwards. Give it at least eight to twelve weeks before judging whether it works. Do not pick or squeeze spots — that is what leaves scars. Wash your hands before and after applying, and cover the area if advised. Do not share towels or bedding while an infection is active.
