Verelan is an extended-release formulation of verapamil, a calcium channel blocker. It lowers blood pressure by blocking calcium from entering the smooth muscle cells of blood vessel walls and the heart, causing the vessels to relax and widen. This reduces the resistance the heart must pump against, which brings blood pressure down.

Verelan (verapamil) is a non-dihydropyridine calcium channel blocker, meaning it also slows electrical conduction in the heart in addition to relaxing blood vessels. Amlodipine is a dihydropyridine that works mainly on blood vessels. Your physician will determine which type is more appropriate based on your specific cardiovascular profile.

Blood pressure-lowering effects can begin within the first few days of starting Verelan, but it may take one to two weeks of consistent daily dosing to see the full therapeutic benefit. Ongoing monitoring is important to ensure your dose is optimized.

Common side effects include constipation, dizziness, headache, and fatigue. Constipation is particularly associated with verapamil and can often be managed with dietary fiber and hydration. Serious side effects such as slow heart rate or swelling of the legs should be reported to your physician promptly.

Verelan can be used alone or as part of a combination regimen, but certain combinations require caution. Verapamil should not be combined with beta-blockers without close physician supervision, as both drugs slow the heart rate and can cause serious bradycardia or heart block. Always share a full medication list with your physician.

Grapefruit and grapefruit juice can increase verapamil blood levels by inhibiting an enzyme in the gut that normally metabolizes the drug. Higher blood levels may intensify side effects. It is generally advisable to avoid grapefruit products while taking Verelan.
