Ospen 1500 (Phenoxymethylpenicillin Potassium)

Phenoxymethylpenicillin potassium, the active ingredient in Ospen 1500, is a penicillin antibiotic presented as a 1500 mg oral tablet for systemic use. It treats susceptible bacterial infections in adults and children.

GNH USA supplies Ospen 1500 as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide.

Phenoxymethylpenicillin potassium is a narrow‑spectrum beta‑lactam antibiotic used for infections caused by susceptible Gram‑positive organisms.

- Streptococcus pharyngitis: reduces symptom duration and bacterial spread. - Acute otitis media: eradicates the causative streptococcal strains. - Skin and soft‑tissue infections: treats mild to moderate infections such as impetigo caused by susceptible organisms. - Rheumatic fever prophylaxis: prevents recurrence of streptococcal‑induced cardiac complications. - Community‑acquired pneumonia: effective against susceptible strains of Streptococcus pneumoniae.

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

Common Side Effects: - Gastrointestinal upset: nausea, abdominal discomfort or diarrhoea. - Skin rash: mild maculopapular eruptions. - Vaginal candidiasis: overgrowth of yeast due to altered flora. - Elevated liver enzymes: transient increase in hepatic transaminases.

Serious or Rare Side Effects: - Anaphylaxis: severe, potentially life‑threatening allergic reaction. - Stevens‑Johnson syndrome: rare mucocutaneous blistering disorder. - Hemolytic anemia: immune‑mediated destruction of red blood cells. - Nephritis: interstitial inflammation of the kidneys.

Phenoxymethylpenicillin potassium should be used with caution in specific clinical situations.

- Allergy assessment: avoid in patients with known penicillin hypersensitivity. - Renal function: dose adjustment may be required in severe renal impairment. - Hepatic disease: monitor liver function tests during prolonged therapy. - Pregnancy and lactation: use only if clearly needed after risk‑benefit evaluation. - Concomitant oral contraceptives: efficacy may be reduced; advise additional contraception. - Store below 25°C: keep in the original container, protect from moisture and direct sunlight.

Phenoxymethylpenicillin potassium can interact with several medicines, affecting efficacy or safety.

Major Interactions (Avoid): - Methotrexate: increased risk of toxicity due to reduced renal clearance. - Probenecid: raises penicillin levels, heightening toxicity risk. - Oral contraceptives: may diminish hormonal effectiveness, increasing pregnancy risk.

Moderate Interactions (Monitor Closely): - Warfarin: potential alteration of INR; monitor coagulation parameters. - Allopurinol: rare reports of rash when combined. - Non‑steroidal anti‑inflammatory drugs (NSAIDs): may increase risk of renal impairment.
