Pharmacist Tips:

  • One of the most common side effects of Norvasc is lower limb swelling, which usually occurs within 2-3 weeks after starting the medication. Because of how calcium channel blockers dilate blood vessels, fluid can accumulate in the lower limbs. If you experience swelling, consult your doctor so they can make changes to your blood pressure medicine.
  • Avoid drinking grapefruit juice whilst you are on this medicine.
  • It may take a few weeks for full effect. Even if you feel well, do not stop taking the medication.

Common dosing schedule:
Norvasc can be taken with or without food. Evening or bedtime dosing may be the best time to take most high blood pressure medicines.
