10 Side Effects of Calcium Channel Blockers
Side Effect #4: Gingival Overgrowth
Gingival overgrowth or gingival enlargement occurs when the size of the gums increases due to side effects of certain medications and inflammatory conditions. Treatment will depend on the underlying cause. Medications that can cause gingival overgrowth include anticonvulsants (phenytoin, lamotrigine, phenobarbital, vigabatrin, topiramate, ethosuximide, and primidone), cyclosporine (immunosuppressant), and calcium channel blockers.
Gingival overgrowth due to medications have been linked to genetic predisposition. In most patients, discontinuation of the medication usually resolves the enlargement of the gums.
