Statins lower cholesterol. They also interact — famously — with grapefruit. But the degree of that interaction depends heavily on which statin you take.

The short answer

  • Simvastatin, lovastatin, atorvastatin: avoid grapefruit.
  • Rosuvastatin, pravastatin, fluvastatin: fine to have grapefruit.

Why we ask

Grapefruit blocks the enzyme (CYP3A4) that metabolizes certain statins. The statin builds up in your bloodstream, raising side-effect risk — muscle pain, in particular. The effect lasts up to 72 hours, which is why "just take it at a different time of day" doesn't work.

If you love grapefruit and take one of the affected statins, ask your doctor about switching to pravastatin or rosuvastatin. Same benefit, different metabolism.
