Patient Information
Verapamil HCl is known as a calcium channel blocker. It is taken to treat high blood pressure, to relieve some
chest pains in patients with angina, or to treat some problems with heart rhythms. Verapamil has several drug
interactions, make sure your physician and pharmacist known all the medicines you are taking so they may properly
advise you. Verapamil HCl is excreted in breast milk. It may be necessary to change therapy or provide an alternate
to breast milk. The most common side effect is constipation. This may be relieved with dietary modification (more
fiber) or laxatives. Sustained release tablets should be taken with food. They should not be broken or crushed. Doses
may need some adjustment, make sure to have your condition monitored regularly.
