Benzphetamine Can Be Expensive — But You Have Options

If you've been prescribed Benzphetamine (Didrex, Regimex) for weight loss, you may have experienced sticker shock at the pharmacy counter. Without insurance, a 90-tablet supply of Benzphetamine 50 mg can cost anywhere from $70 to over $625, depending on the pharmacy.

The wide price range means where you fill your prescription matters a lot. And since many insurance plans don't cover weight loss medications, most patients are paying out of pocket. The good news is that there are several ways to bring the cost down significantly.

How Much Does Benzphetamine Cost Without Insurance?

Here's what you can expect to pay for Benzphetamine without any discounts or insurance:

• 90 tablets (50 mg) at retail price: $128 to $625, depending on the pharmacy
• 30 tablets (50 mg) at retail price: $40 to $210
• Per-tablet retail cost: Approximately $1.40 to $7.00

These prices vary widely because different pharmacies negotiate different rates with their distributors. Chain pharmacies tend to charge more, while some independent pharmacies or warehouse-style pharmacies may offer lower prices.

Using Discount Cards and Coupons

Prescription discount cards are the easiest way to save on Benzphetamine. These cards are free to use and can reduce your cost by 40% to 80%. Here are the top options:

SingleCare

SingleCare offers some of the best prices for Benzphetamine. With a SingleCare coupon, you can pay as little as $70.59 for 90 tablets of Benzphetamine 50 mg — a savings of over $57 off the average cash price of $127.84. Visit singlecare.com to find your price.

Several other discount card programs may offer competitive pricing:

Pro tip: Prices vary between discount cards and between pharmacies. Always compare at least 2 to 3 cards before filling your prescription. The difference can be $30 to $50 or more.

Does Insurance Cover Benzphetamine?

Coverage for Benzphetamine is limited:

• Many private insurance plans do not cover weight loss medications at all
• Plans that do cover it often require prior authorization — your doctor must submit documentation showing medical necessity
• Step therapy may be required — your insurer may want you to try Phentermine (a cheaper alternative) first
• Medicare Part D generally does not cover weight loss medications, including Benzphetamine
• Medicaid coverage varies by state, but most state Medicaid programs exclude weight loss drugs

If you have insurance, it's still worth checking. Call the number on the back of your insurance card and ask: "Is Benzphetamine covered under my pharmacy benefit? Is prior authorization required?"

Patient Assistance Programs

Unlike many brand-name medications, Benzphetamine does not currently have a manufacturer-sponsored patient assistance program or savings card. Since the drug is available generically and has no single major brand sponsor, there are no manufacturer coupons to use.

However, there are other resources that may help:

NeedyMeds

NeedyMeds is a nonprofit that helps patients find assistance programs for medications. While there's no Benzphetamine-specific program, NeedyMeds offers a free drug discount card that may provide savings at participating pharmacies.

RxAssist

RxAssist maintains a database of patient assistance programs. Check their site for any new programs that may become available.

State and Local Programs

Some states and local health departments offer prescription assistance programs for low-income residents. Contact your local health department or 211 hotline to ask about available resources.

Other Ways to Save on Benzphetamine

Always Choose Generic

Benzphetamine is available in generic form from multiple manufacturers. Generic Benzphetamine is chemically identical to the brand-name versions (Didrex, Regimex) and is significantly cheaper. Always confirm that your pharmacy is dispensing the generic version.

Compare Pharmacy Prices

Prices for the same medication can vary by hundreds of dollars between pharmacies. Use Medfinder to find pharmacies that have Benzphetamine in stock, then compare prices using discount cards. Independent pharmacies and warehouse pharmacies (like Costco) sometimes offer the lowest prices.

Ask About 30-Day vs. 90-Day Supplies

Some pharmacies offer a lower per-tablet price when you fill a 90-day supply instead of 30 days. If your prescription allows it and you can afford the upfront cost, a larger supply may save you money over time.

Talk to Your Doctor About Lower-Cost Alternatives

If cost is a major barrier, your doctor may recommend switching to Phentermine, which can cost as little as $10 per month with a discount card. Other alternatives like Diethylpropion ($20–$80/month) and Phendimetrazine ($15–$60/month) may also be more affordable. Read our guide on alternatives to Benzphetamine.

Ask About Pill Splitting

Benzphetamine 50 mg tablets are scored, meaning they can be split in half. If your doctor has prescribed 25 mg doses, you may be able to save by getting 50 mg tablets and splitting them. Only do this if your doctor approves it — never change your dose on your own.

Always compare prices across pharmacies, choose generic, and ask your doctor about lower-cost alternatives if needed.
