Procardia is a very safe medication, and we have never been forced to terminate its use because of side effects. Use of procardia may drop the blood pressure of a normal individual slightly, but this does not affect a patient's ability to continue taking her medication. Some patients experience mild palpitations for the same reason and others complain of skin redness in the bodyÕs lower extremities when standing upright, but this often disappears when the patient goes to bed. There are no known fetal complications caused by the use of Procardia, and in many instances in the past we used Nifedipine to treat fetal tachycardia (fast heart rate).
