Maxigan

Clarithromycin, the active ingredient in Maxigan, is a macrolide antibiotic presented as a tablet for oral use. It treats a variety of bacterial infections in adults and children when prescribed by a healthcare professional.

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

Clarithromycin is used to treat infections caused by susceptible bacteria across several organ systems.

- Community‑acquired pneumonia: eradicates typical bacterial pathogens and improves respiratory function. - Acute bacterial sinusitis: relieves sinus inflammation and clears infection. - Skin and soft tissue infections: eliminates susceptible Gram‑positive organisms. - Helicobacter pylori eradication: forms part of combination therapy to eradicate the bacterium. - Other susceptible bacterial infections: provides coverage for a range of Gram‑positive and some Gram‑negative organisms.

Clarithromycin may cause a range of adverse reactions, most of which are mild and reversible.

Common Side Effects: - Nausea: mild to moderate upset stomach. - Diarrhea: loose stools, often self‑limiting. - Abdominal pain: cramping or discomfort. - Taste disturbance: altered or metallic taste. - Headache: mild to moderate intensity. - Vomiting: occasional episodes.

Serious or Rare Side Effects: - Anaphylaxis: severe allergic reaction requiring immediate medical attention. - QT prolongation: potential cardiac arrhythmia risk. - Hepatic dysfunction: elevated liver enzymes or hepatitis. - Clostridioides difficile‑associated diarrhea: severe colitis. - Stevens‑Johnson syndrome: rare severe skin reaction. - Neutropenia: marked reduction in white blood cells.

Before initiating Clarithromycin therapy, consider the following safety measures.

- Assess renal function: adjust use in severe renal impairment. - Review hepatic status: use cautiously in patients with liver disease. - Monitor cardiac rhythm: avoid in individuals with known QT prolongation. - Avoid use with macrolide‑resistant organisms: ensure susceptibility testing. - Counsel on gastrointestinal upset: advise taking with food if tolerated. - Store at ambient temperature: keep in the original pack, protect from moisture and light.

Clarithromycin interacts with several medicines; awareness helps prevent adverse outcomes.

Major Interactions (Avoid): - Strong CYP3A4 inhibitors (e.g., itraconazole, ketoconazole): may increase clarithromycin levels and toxicity. - QT‑prolonging drugs (e.g., quinidine, sotalol): combined use raises risk of arrhythmia. - Statins metabolized by CYP3A4 (e.g., simvastatin): heightened risk of myopathy.

Moderate Interactions (Monitor Closely): - Warfarin: clarithromycin can enhance anticoagulant effect; monitor INR. - Antacids containing aluminum or magnesium: may reduce absorption; separate dosing by at least 2 hours. - Oral contraceptives: possible reduction in efficacy; advise backup contraception.
