Description
Clavulin is a combination antibiotic containing amoxicillin (a penicillin-type antibiotic) and clavulanic acid (a beta-lactamase inhibitor). This formulation broadens the antibacterial spectrum of amoxicillin by inhibiting beta-lactamase enzymes produced by resistant bacteria. Clavulin is indicated for the treatment of various infections caused by susceptible strains of bacteria, including infections of the respiratory tract, urinary tract, skin and soft tissue, and otitis media. It is available in multiple formulations, including tablets, chewable tablets, and oral suspension.

Directions
Clavulin should be taken orally, typically every 8 or 12 hours depending on the formulation and severity of infection. It should be taken at the start of a meal to enhance absorption and reduce gastrointestinal discomfort. The dosage and duration depend on the patient’s age, weight, renal function, and the type and severity of infection. Prescribers should follow local antimicrobial guidelines when determining treatment duration. Tablets should not be split unless scored and approved for that use.
Ingredients
Active Ingredients:
- Amoxicillin (as amoxicillin trihydrate)
- Clavulanic acid (as potassium clavulanate)
Inactive Ingredients vary by formulation but may include:
- Colloidal silicon dioxide, magnesium stearate, microcrystalline cellulose, and flavoring agents (for suspensions and chewables).
Contraindications
Clavulin is contraindicated in patients with:
- A history of hypersensitivity to beta-lactam antibiotics (e.g., penicillins, cephalosporins)
- A previous history of cholestatic jaundice or hepatic dysfunction associated with clavulanate-containing products
Cautions
Use with caution in patients with hepatic impairment, renal dysfunction, or a history of antibiotic-associated colitis. Periodic monitoring of liver, renal, and hematologic function is advised during prolonged therapy. Dosage adjustments may be required in patients with moderate to severe renal impairment. Clavulin should not be used for viral infections. Prolonged use may result in fungal or bacterial superinfection, including Clostridioides difficile-associated diarrhea.
Side Effects
Common side effects may include:
Less common but potentially serious side effects include:
- Hepatic dysfunction (including hepatitis and cholestatic jaundice)
- Hypersensitivity reactions (e.g., anaphylaxis, angioedema)
- Blood disorders (e.g., thrombocytopenia, anemia)
