Keep using Plendil as directed, even if you feel well. High blood pressure often has no symptoms. You may need to use blood pressure medication for the rest of your life.
Brush and floss your teeth regularly while taking this medication. Plendil can cause mild swelling of your gums, which may be avoided with good dental hygiene.
Do not crush, chew, or break an extended-release Plendil tablet. Swallow it whole. Breaking the pill may cause too much of the drug to be released at one time.
