What brand names does verapamil come in?
Verapamil is sold under multiple brand names depending on the country and the specific formulation (immediate-release tablets, extended-release tablets/capsules, and injections). Common brand names include Calan and Verelan, along with other local brands that can vary by market.
What are the most common U.S. verapamil brand names?
In the U.S., verapamil is widely known under these brand names:
- Calan (verapamil hydrochloride)
- Calan SR (sustained release)
- Verelan (extended-release)
- Verelan PM (extended-release, often at night dosing)
Does the brand name change depending on whether it’s extended-release?
Yes. The same active ingredient (verapamil) can appear under different brand names based on the release type:
- Immediate-release products often use different brand labeling than extended-release versions.
- Extended-release products are typically designed for once-daily or similar dosing schedules, and brand names usually reflect that formulation.
Is verapamil also available as a generic?
Yes. Verapamil has generic versions (verapamil hydrochloride) that can be substituted for many brand products, depending on local pharmacy and prescribing rules.
Can patients safely switch between brands or release types?
Patients should not switch between different verapamil brand names or release formulations without a prescriber/pharmacist’s guidance, because immediate-release vs extended-release verapamil products can have different dosing schedules and blood levels.
