Paxlovid
Lovastatin is a medicine that helps lower cholesterol levels in your blood. It belongs to a class of drugs called statins.
Paxlovid is a medicine used to treat mild to moderate COVID-19 in adults. It helps prevent severe illness, hospitalization, or death in people at high risk.
Lovastatin is used to lower cholesterol and reduce the risk of heart problems. It can help prevent heart attacks, unstable angina (chest pain), and the need for procedures to open blocked arteries. It's also used to slow down the hardening of arteries in people who already have heart disease. Lovastatin can also be used in children 10-17 years of age with high cholesterol due to genetic causes.
Paxlovid treats mild to moderate COVID-19 in adults. You must be at high risk of your illness becoming severe. This includes needing to go to the hospital or possibly dying from COVID-19. Paxlovid is not for preventing COVID-19 before or after exposure.
Lovastatin works by blocking a substance your body needs to make cholesterol. This helps to lower the amount of cholesterol in your blood. Lowering cholesterol helps to prevent heart disease and stroke.
Paxlovid contains two medicines, nirmatrelvir and ritonavir. Nirmatrelvir stops the virus from multiplying in your body. Ritonavir helps nirmatrelvir stay in your body longer so it can work better.

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, lovastatin has 6,520 submissions while nirmatrelvir/ritonavir has 56,802. Those figures reflect cumulative reporting volume, not per-patient risk, so older, widely dispensed drugs typically look worse on count alone.
