Gramicidin

Introduction

Gramicidin is an antibiotic compound primarily used for topical treatment of bacterial infections. It is often included in combination with other antibiotics in creams, ointments, and eye or ear drops. Gramicidin works effectively against Gram-positive bacteria, making it a valuable choice for infections involving the skin, eyes, and ears. It is not used for systemic infections due to its toxicity when taken orally or injected. Available in various formulations, Gramicidin helps provide quick relief and healing by targeting the bacteria directly at the site of infection.

Uses of Gramicidin

• Treatment of minor skin infections
• Eye infections such as conjunctivitis
• Ear infections including otitis externa
• Wound care and prevention of bacterial growth
• Burn-related infections

How Gramicidin works

Gramicidin works by disrupting the bacterial cell membrane. It creates channels or pores in the membrane, leading to the leakage of essential ions and ultimately causing the death of the bacteria. This mechanism is effective mainly against Gram-positive bacteria and ensures localized treatment without affecting human cells.

Benefits of Gramicidin

• Effective against a wide range of Gram-positive bacteria
• Provides localized treatment with minimal systemic side effects
• Promotes faster healing of wounds and infections
• Available in combination with other antibiotics for broader coverage

How to take Gramicidin

Gramicidin should be used exactly as prescribed by your healthcare provider. For skin infections, apply the ointment or cream to the affected area 2–3 times daily. For eye or ear infections, use the prescribed number of drops and avoid contamination of the dropper tip. Do not ingest or inject Gramicidin. Follow the full course of treatment even if symptoms improve early.
