Verapamil Special Warnings

Verapamil and Heart Failure

Verapamil has been reported to cause heart failure (condition where heart can’t pump as well) or pulmonary edema (fluid in the lungs) in some people.

You should not take Verapamil if you have:

  • Severe heart abnormalities (such as severe left ventricular dysfunction)
  • Moderate to severe symptoms of heart failure
  • Ventricular dysfunction (heart irregularities) and if you are also receiving beta blockers

People with milder ventricular dysfunction should, if possible, be controlled on optimum doses of digitalis and/or diuretics before starting treatment with Verapamil.


Verapamil and Low Blood Pressure

Sometimes, the effects of Verapamil may cause a decrease in blood pressure below normal levels, which may result in dizziness or symptomatic low blood pressure (.

What is your blood pressure? Keeping a blood pressure log if you have been diagnosed with high blood pressure is a very good way to be prepared to speak with your doctor and be aware of any changes in your condition.


Verapamil and Elevated Liver Enzymes

Verapamil has been reported to cause increased liver enzyme levels that are sometimes temporary and even disappear when treatment with Verapamil is continued. Several cases of liver injury have been reported with symptoms of discomfort, fever, and/or right upper quadrant pain (just below your ribs) in addition to increased liver enzymes in blood levels. If you are taking Verapamil, it is prudent to have your liver function monitored periodically.
