How much does metformin 500 mg cost (typical US cash price vs. with insurance)?
Metformin is an inexpensive, widely available generic medicine, so the price for a 500 mg tablet mainly depends on whether you’re paying cash, using insurance, or getting a pharmacy discount (and how many tablets you need per month). Cash prices can vary a lot by pharmacy and by the specific product strength (extended-release vs. immediate-release), even though the active ingredient is the same.
What price should you expect for a 30-day supply of metformin 500 mg?
A common pricing check is “per 30-day supply,” since that’s how most pharmacies quote cost. Your final number will depend on:
- Pill count per day (for example, 1 tablet twice daily is different from 2 tablets twice daily)
- Immediate-release vs. extended-release formulation
- Brand/product name and manufacturer
- Your ZIP code and pharmacy (CVS, Walgreens, Walmart, etc.)
If you tell me your daily dose (how many 500 mg tablets per day) and whether it’s immediate-release or extended-release, I can help you estimate the likely total for a month and what to compare when you check prices.
Does “metformin 500 mg” mean immediate-release or extended-release—and does that change the cost?
Yes. “Metformin 500 mg” can refer to:
- Metformin immediate-release tablets (often written as metformin HCl)
- Metformin extended-release tablets (often written as metformin ER)
Extended-release versions can cost more than immediate-release in some pharmacies, even when both are generic.
Can you get metformin for a lower price than pharmacy cash prices?
Often, yes. Many people lower out-of-pocket cost by using:
- A pharmacy discount program (varies by pharmacy)
- Generic-to-generic price comparisons across chains
- Manufacturer or pharmacy coupons (availability varies)
If you share your pharmacy and ZIP code, I can suggest the best “price-check” approach for your situation.
What’s the cheapest option if you’re paying without insurance?
The lowest cash price often comes from comparing multiple stores (especially discount retailers) and confirming you’re getting the generic. Generic metformin is typically far cheaper than brand versions.
Are there price differences by manufacturer?
Sometimes. Even though metformin 500 mg is generic, different manufacturers and tablet types can carry slightly different pricing at the same pharmacy.
