Crestor with antibiotics: interactions and safety
Antibiotic courses are common, short-term and often combined with chronic medications such as Crestor (Rosuvastatin). Most antibiotics do not interfere meaningfully with Rosuvastatin at 5mg, 10mg, 20mg, 40mg, but a few classes do, and a small number of combinations are best avoided.
Common antibiotic interactions
Macrolides (clarithromycin, erythromycin) and certain antifungals can inhibit hepatic metabolism (CYP3A4) and raise plasma levels of many medications including some Cardiovascular Medications agents. Rifampicin has the opposite effect, accelerating metabolism. Most penicillins, cephalosporins, fluoroquinolones and tetracyclines have no clinically meaningful interaction with Rosuvastatin at 5mg, 10mg, 20mg, 40mg.
Practical guidance
According to the prescribing information for Rosuvastatin, an antibiotic course should be reviewed by the prescriber or pharmacist for known interactions before Crestor is co-administered. Adjusted 5mg, 10mg, 20mg, 40mg dosing or temporary substitution is sometimes preferred for the duration of the antibiotic course.
Frequently asked questions
Can I take Crestor during an antibiotic course? ▾
For most common antibiotics, yes. A few classes — notably macrolides and azole antifungals — alter how Rosuvastatin is metabolised and may need a temporary 5mg, 10mg, 20mg, 40mg adjustment. The prescribing pharmacist should review any new antibiotic against the existing Crestor regimen.
Will antibiotics make Crestor stop working? ▾
Most antibiotics do not affect Crestor efficacy. Rifampicin and a few others can lower Rosuvastatin levels and reduce effect; in those cases the prescriber may adjust the dose during and shortly after the antibiotic course.
