Pharmacist tips for Diltiazem (Cardizem)

pharmacist
  • Diltiazem (Cardizem) can cause dizziness or fatigue when you first start taking it or when your provider raises your dose. Hold onto something sturdy so that you don't fall when standing up from a seated or lying down position.
  • Since diltiazem (Cardizem) wears off quickly, take it throughout the day at the same times each day. A good way to remember to take it is to take it before meals (e.g., breakfast, lunch, and dinner) and before bedtime.
  • You can crush or chew diltiazem (Cardizem) tablets. Make sure, however, that you're actually taking diltiazem (Cardizem) and not the extended-release version of this medication. The extended-release version must be swallowed whole.
  • Tell your provider and pharmacist about all of the medications that you're taking. Diltiazem (Cardizem) may interact with other medications such as statins (for cholesterol) and blood pressure medications.
