Lescol
Clarithromycin is an antibiotic that fights bacterial infections. It belongs to a class of drugs called macrolides.
Fluvastatin (Lescol) is a medicine that helps lower cholesterol levels in your blood. It belongs to a group of drugs called statins.
Clarithromycin treats mild to moderate infections caused by certain bacteria. It can treat bronchitis, sinus infections, pneumonia, and throat/tonsil infections. It also treats skin infections, ear infections in children, certain mycobacterial infections, and H. pylori infections that cause ulcers.
This medicine is used to lower high cholesterol and triglycerides (fats) in adults and children (10-16 years old) with certain inherited cholesterol problems. It can also lower the risk of needing procedures to improve blood flow to the heart in adults with heart disease. Fluvastatin can also slow down the hardening of arteries in people with heart disease.
Clarithromycin works by stopping the growth of bacteria. It prevents bacteria from making proteins they need to survive. This helps your body fight off the infection.
Fluvastatin works by blocking a substance your body needs to make cholesterol. This helps to lower bad cholesterol (LDL) and triglycerides while raising good cholesterol (HDL). By lowering cholesterol, it helps prevent heart disease and stroke.

How to Read This clarithromycin vs fluvastatin Comparison
clarithromycin is classified in the Macrolide Antibiotic drug class, while fluvastatin sits within the HMG-CoA Reductase Inhibitor (Statin) class. Drugs from different classes work through distinct mechanisms, so a head-to-head comparison illustrates trade-offs rather than equivalence. Both drugs are prescription-only, so a licensed provider must authorize use.
Adverse event totals above are pulled from the FDA's Adverse Event Reporting System (FAERS). For these top-ranked reactions alone, clarithromycin has 10,666 submissions while fluvastatin has 2,078. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone. These two drugs have a known major interaction flagged in FDA labeling, attributed to clarithromycin can affect how your body handles cholesterol medications, though it does not significantly change the levels of fluvastatin.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
A table cannot substitute for clinical judgment. Effectiveness, tolerability, drug-drug interactions with your other medications, kidney and liver function, pregnancy status, insurance formulary, and price all feed into a decision that only a licensed prescriber can make responsibly. Data here is sourced from FDA Structured Product Labels (SPL) and FAERS, both of which update as manufacturers and clinicians submit new information.
