NHS Warns Grapefruit Can Interfere With Some Statins

Guidance explains grapefruit compounds inhibit CYP3A4, which can raise levels of certain statins.

Overview

  • The NHS website highlights particular concern for simvastatin and atorvastatin, noting that not all statins are affected.
  • Patients are advised to review their medicine leaflets and seek advice from a GP or pharmacist if unsure about interactions.
  • Elevated statin levels can heighten the risk of side effects, with rare but serious harms including muscle injury, liver damage and kidney problems.
  • Clinicians may recommend avoiding or limiting grapefruit juice, lowering the dose, switching to a different statin, or temporarily pausing treatment.
  • The reminder comes as an estimated 8–10 million UK adults take statins, with blood tests recommended before starting and again at around three and twelve months.
