Metronidazol Actavis

Metronidazole, the active ingredient in Metronidazol Actavis, is a nitroimidazole antibiotic presented as a topical formulation for cutaneous use. It is employed to treat bacterial skin infections, rosacea and acne vulgaris in patients requiring topical antimicrobial therapy.

GNH USA supplies Metronidazol Actavis as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Metronidazole is indicated for dermatologic conditions caused by anaerobic bacteria or protozoa, acting on the skin surface to reduce microbial load.

- Bacterial skin infections: eliminates susceptible anaerobic bacteria, helping resolve cellulitis, impetigo and infected wounds. - Rosacea: reduces inflammatory lesions and erythema associated with papulopustular rosacea. - Acne vulgaris: decreases Propionibacterium acnes colonisation, improving acne lesions.

Metronidazole may cause local and systemic adverse reactions, most of which are mild and reversible.

Common Side Effects: - Skin irritation: burning, stinging or itching at the application site. - Dryness or peeling of the treated skin. - Redness or mild erythema. - Pruritus (itching). - Mild allergic dermatitis. - Transient discoloration of the skin.

Serious or Rare Side Effects: - Stevens‑Johnson syndrome or toxic epidermal necrolysis. - Severe allergic reaction with swelling, hives or difficulty breathing. - Photosensitivity leading to exaggerated sunburn. - Persistent ulceration or necrosis of the skin. - Systemic toxicity if absorbed in large amounts. - Neurological symptoms such as seizures (very rare).

Before using Metronidazol Actavis, consider the following safety measures.

- Allergy assessment: confirm no known hypersensitivity to metronidazole or nitroimidazoles. - Skin integrity: avoid application on extensive open wounds or damaged skin. - Alcohol avoidance: do not consume alcohol during treatment to prevent disulfiram‑like reactions. - Monitor for severe reactions: discontinue and seek medical help if signs of Stevens‑Johnson syndrome appear. - Store at room temperature: keep in the original packaging, protect from moisture and light.

Metronidazole can interact with several medicines; some require avoidance while others need close monitoring.

Major Interactions (Avoid): - Alcohol: may cause severe flushing, nausea, vomiting, and tachycardia. - Warfarin: increased anticoagulant effect, raising bleeding risk. - Lithium: heightened lithium toxicity, leading to tremor, confusion, or renal issues.

Moderate Interactions (Monitor Closely): - Cimetidine: may increase metronidazole plasma levels. - Isoniazid: potential for enhanced neurotoxicity. - Phenytoin: may reduce metronidazole efficacy, requiring dose adjustment.
