Amlodipine with simvastatin: the 20 mg limit

Taking amlodipine and simvastatin together? There's an important drug interaction every patient should know about!

Amlodipine (Norvasc) is commonly prescribed for high blood pressure, while simvastatin (Zocor) helps lower cholesterol.

• HERE'S THE IMPORTANT INTERACTION:

Amlodipine can increase the amount of simvastatin in your bloodstream, raising the risk of muscle-related side effects.

The FDA recommends limiting simvastatin to 20 mg daily when taken with amlodipine.

This applies whether you're taking amlodipine 5 mg or 10 mg.

• PHARMACIST TAKEAWAY:

Taking these medications together isn't automatically unsafe, but your simvastatin dose matters!

If you take both medications, ask your pharmacist to review the combination. Report unexplained muscle pain, tenderness, or weakness, especially if accompanied by dark urine or feeling unwell.

Never change or stop prescription medications without discussing them with your healthcare professional.

• Do you take more than one medication for blood pressure or cholesterol? Have you ever asked your pharmacist to check for interactions?
