Is diltiazem expensive?

Short answer: it can be inexpensive if you use the generic version, but brand-name diltiazem can be much more expensive. Prices vary a lot depending on country, pharmacy, dose, and whether you have insurance or discount programs.

What affects the cost
- Formulation: generic diltiazem hydrochloride (IR or SR) is usually cheaper than brand-name versions (Cardizem, Cardizem CD, Tiazac).
- Dose/strength: higher-dose strengths cost more.
- Insurance coverage and formulary status: copays can be very low or even $0 for generics.
- Pharmacy and location: cash prices differ between pharmacies and regions.

Typical guidance (U.S. context)
- With a generic: out-of-pocket for a 30-day supply often ranges from a few dollars up to about $20–30, depending on dose and insurance.
- Brand-name (if not discounted): can be substantially higher; sometimes $50–$200+ per month, though coupons or patient-assistance programs can help.

If cost is a concern
- Ask your prescriber about switching to the generic form if you’re on a brand-name version.
- Compare prices at different pharmacies or use discount programs (GoodRx, SingleCare) or mail-order/pharmacy plans.
- Check if you qualify for any manufacturer or patient-assistance programs (more common with newer or brand-name meds).
- If you’re in a country outside the U.S., tell me your country and I can give a more tailored estimate.

If you’d like, tell me:
- Your country
- The exact dose and formulation (e.g., diltiazem IR 30 mg, SR 240 mg, etc.)
- Whether you have insurance (and the plan), or if you’re paying cash

I can help estimate current costs or help you compare options. And as always, discuss any cost concerns with your prescriber to ensure the switch (if any) is clinically appropriate.
