  • What is the most important information I should know about Plendil?

Since blood pressure declines gradually, it may be several weeks before you get the full benefit of Plendil; you must continue taking it even if you are feeling well. Plendil does not cure high blood pressure; it works to keep it under control.

    Plendil can cause your blood pressure to become too low. If you feel lightheaded or faint, or if you feel your heart racing or experience any chest pain, contact your doctor immediately.

    Your legs and feet may swell when you start taking Plendil, usually within the first 2-3 weeks of treatment. Your gums may become swollen and sore while you are taking Plendil. Good dental hygiene will help control this problem.
