Verelan is used to treat hypertension (high blood pressure), angina (chest pain), and certain cardiac arrhythmias, particularly supraventricular arrhythmias. It may be prescribed when a once-daily dosing option is preferred for patient convenience.
Verelan contains verapamil, a non-dihydropyridine calcium channel blocker. It works by blocking calcium from entering the smooth muscle cells of blood vessels and the heart. This causes blood vessels to relax and dilate (vasodilation), reduces the force of heart contractions, and slows electrical conduction through the heart's atrioventricular node.
Verelan should be taken exactly as prescribed, typically once daily with food. It may interact with other medications including beta-blockers, digoxin, and certain statins. Common side effects include constipation, dizziness, headache, and low blood pressure. Patients with certain heart conditions (like severe heart failure, sick sinus syndrome, or AV block without a pacemaker) should not use this medication. Grapefruit juice may increase drug levels and should be avoided.
