An irregular heartbeat is listed as a possible side effect of Norvasc (for one). If this condition does occur will it reverse if use of the product is stopped.
Thanks for your question.
Norvasc is a calcium channel blocker that is used in the treatment of high blood pressure. It works by relaxing the smooth muscle in arteries causing a widening (called vasodilatation) of these blood vessels which results in lower blood pressure. Though not a common side effect, some patients experience palpitations and can develop abnormal cardiac rhythms.
These abnormal rhythms and other side effects usually revert back to normal if the drug is withdrawn.
I suggest you discuss this with your doctor. No drug dosage should be changed or drug discontinued without the knowledge of your physician.
I hope this has been helpful.
