Klavophar (Amoxicillin, Clavulanic Acid)

Klavophar, a penicillin‑beta‑lactamase inhibitor combination, is used to treat bacterial infections of the respiratory, urinary and skin systems.

• Sinusitis: helps eradicate the causative bacteria and relieve sinus inflammation.
• Otitis media: clears middle‑ear infection and reduces pain and fever.
• Pneumonia: combats the bacterial pathogens responsible for community‑acquired pneumonia.
• Urinary tract infection: eliminates the infecting organisms and resolves urinary symptoms.
• Skin and soft tissue infections: treats cellulitis and other bacterial skin conditions.

• Amoxicillin binds to penicillin‑binding proteins, inhibiting the final stage of bacterial cell‑wall peptidoglycan synthesis, which leads to cell lysis. Clavulanic acid, a β‑lactamase inhibitor, irreversibly binds to bacterial β‑lactamases, protecting amoxicillin from enzymatic degradation and extending its antimicrobial spectrum against β‑lactamase‑producing organisms.

Adverse reactions to Klavophar may vary in frequency and severity.

Common Side Effects

• Nausea: mild to moderate stomach upset.
• Diarrhea: loose stools, sometimes watery.
• Rash: mild skin erythema or itching.
• Vomiting: occasional emesis.
• Headache: transient cranial discomfort.

Serious or Rare Side Effects

• Anaphylaxis: severe allergic reaction with airway compromise.
• Stevens‑Johnson syndrome: rare skin and mucous membrane disorder.
• Hepatotoxicity: elevated liver enzymes or jaundice.
• Clostridioides difficile colitis: severe diarrhea due to bacterial overgrowth.
• Hemolytic anemia: destruction of red blood cells.

Before prescribing Klavophar, consider the following precautions and warnings.

• Allergy assessment: avoid use in patients with known hypersensitivity to penicillins or β‑lactamase inhibitors.
• Liver function: monitor in patients with hepatic impairment as metabolism may be reduced.
• Renal function: dose adjustment may be required for severe renal insufficiency.
• Pregnancy and lactation: use only if clearly needed; risk–benefit should be evaluated.
• Concomitant antibiotics: avoid using other bactericidal β‑lactams simultaneously.
• Store at ambient temperature: keep below 25 °C in the original packaging, protect from moisture.

Klavophar can interact with other medicines, altering efficacy or safety.

Major Interactions (Avoid)

• Allopurinol: may increase risk of rash.
• Oral anticoagulants (e.g., warfarin): can enhance anticoagulant effect, requiring INR monitoring.
• Methotrexate: reduced renal clearance may raise toxicity.

Moderate Interactions (Monitor Closely)

• Probenecid: decreases renal excretion of amoxicillin, increasing plasma levels.
• Oral contraceptives: may reduce effectiveness, advise additional contraceptive measures.
• Diuretics (e.g., furosemide): may increase risk of electrolyte disturbances.
