Nifedipine Dosage: An Introduction

The dose of nifedipine that your healthcare provider recommends will vary, depending on a number of factors, including:
 
  • The particular nifedipine product
  • The medical condition being treated
  • Other medical conditions you may have
  • Other medications you may be currently taking.
     
As is always the case, do not adjust your nifedipine dose unless your healthcare provider specifically instructs you to do so.
 

Extended-Release Nifedipine Dosing

The recommended starting dose for extended-release nifedipine tablets is nifedipine 30 mg to 60 mg, taken once daily, depending on the particular product. If necessary, your healthcare provider may increase your dose up to nifedipine 90 mg once daily.

General Information on Dosing With Nifedipine

Considerations for people taking nifedipine include the following:
 
  • The medication comes in tablet and capsule form. It is taken by mouth, usually one to four times per day, depending on the particular form of nifedipine.
     
  • Adalat CC®, Afeditab CR®, and Nifediac CC® should be taken on an empty stomach. You can take Nifedical XL®, Procardia®, or Procardia XL® with or without food.
     
  • Because nifedipine tablets are extended-release, they should not be broken, crushed, or chewed. Be sure to swallow the tablets whole.
     
  • Even though nifedipine capsules are not extended-release, they should be swallowed whole as well.
     
  • The medication should be taken at the same time(s) each day to maintain an even level in your blood.
     
  • For nifedipine to work properly, it must be taken as prescribed. The medication will not work if you stop taking it.
     
  • If you are unsure about anything related to nifedipine or your nifedipine dosage, talk to your doctor, nurse, or pharmacist. Do not stop taking the drug without discussing it with your healthcare provider.
