Beta-lactamase inhibitor
Clavulanate with statins (atorvastatin, rosuvastatin, simvastatin)
Statins are among the most widely prescribed chronic medications, often used alongside many other agents including Clavulanate (Clavulanate). The combination at 500/125mg, 875/125mg, 1000/62.5mg is generally safe, but a small number of statin-specific interactions matter — particularly for simvastatin, which shares CYP3A4 metabolism with several common medications.
How Clavulanate interacts with statins
Statins differ in their metabolic pathways: simvastatin and atorvastatin go through CYP3A4 most heavily; rosuvastatin and pravastatin take other routes and have fewer drug interactions. If Clavulanate acts on CYP3A4, the combination with simvastatin or atorvastatin can raise statin levels and increase muscle-related side effects. Clavulanate binds irreversibly to the active site of many class A beta-lactamases produced by bacteria, acting as a 'suicide inhibitor'.
Practical guidance
According to the prescribing information for Clavulanate, anyone on a statin should mention it before starting Clavulanate at 500/125mg, 875/125mg, 1000/62.5mg. The prescriber may switch the statin (e.g. from simvastatin to rosuvastatin) or adjust the statin dose during Clavulanate use. Persistent muscle pain, weakness or dark urine on the combination warrants prompt evaluation.
Frequently asked questions
Can I take Clavulanate with my statin? ▾
For most users at 500/125mg, 875/125mg, 1000/62.5mg, yes — particularly with rosuvastatin or pravastatin which have minimal interactions with Clavulanate. Simvastatin and atorvastatin combinations may need a dose review by the prescriber to avoid amplified statin effects.
Will Clavulanate cause muscle pain with my statin? ▾
Muscle pain is the most common statin side effect and can be amplified when combined with medications that raise statin plasma levels. Persistent or new muscle pain on Clavulanate at 500/125mg, 875/125mg, 1000/62.5mg should be reported promptly so the prescriber can review the combination.
