Is there a generic for Zepbound?

If you’re considering Zepbound (tirzepatide) for weight loss, you’re probably aware that this brand-name medication comes with a high price tag. Given that, it’s natural to wonder: Is there a generic for Zepbound? The short answer: No, and it won’t be for quite some time.

When will generic Zepbound be available? And what is the generic name for Zepbound? Below, find out what you need to know about generic Zepbound, plus which lower-cost GLP-1 medications are available now.

No, there is currently no generic version of Zepbound. There’s also no generic version of Mounjaro, another GLP-1/GIP drug with tirzepatide, the same active ingredient as Zepbound.

The earliest a generic Zepbound could be available is around 2039. That’s when the last patent on Zepbound expires. 

“Zepbound is pretty early in its lifecycle,” says Supriya Rao, MD, a quadruple board-certified physician in internal medicine, gastroenterology, obesity medicine, and lifestyle medicine. 

Zepbound is manufactured by Eli Lilly, which also holds the patents for brand-name Mounjaro and Foundayo. Other companies cannot sell generic Zepbound in the United States until all of those patents expire. 

Dr. Rao says that, in addition to the main patent for the drug itself, Zepbound may be protected by additional patents covering formulation, dosing, and delivery mechanism. 

Even when a brand-name drug’s patents expire, it can take time for a generic version to reach the market. Generic drug manufacturers must develop their own version of the drug and submit it to the US Food and Drug Administration (FDA) to prove it meets the same quality standards, contains the same active ingredient, and works the same way as the brand-name medication. This process takes time.

Generic tirzepatide — or another generic name chosen by the drug manufacturer — won’t be available until around 2039, possibly later.

There’s no way to know exactly how much a generic Zepbound will cost. 

Here’s what we do know:

• Generic medications tend to cost 20%–80% less than their brand-name counterparts. 

• The current list price of Zepbound ranges from $499 to $1,086 per fill. 

• If generic Zepbound costs 50% less, it could be listed anywhere from $250 to $543 per fill. 

Generally, the cost of generic drugs falls as more manufacturers enter the market. “Usually, the first generic version is only about 10%–30% cheaper than the brand-name drug,” says Oluwatosin Ajao, MD, a board-certified internal medicine, lifestyle, and obesity medicine physician.

While the list price of Zepbound without insurance can exceed $270 per week, most people don’t pay full price.

There are three main ways to lower your out-of-pocket cost for Zepbound:

1. Zepbound KwikPen 

The Zepbound KwikPen is a multi-dose pen that is available as a cash-pay option on Ro. 

The price you pay for each Zepbound KwikPen depends on your prescribed dose. 

• 2.5 mg: $299/mo

• 5 mg: $399/mo

• 7.5 mg–15 mg: $449/mo (with manufacturer offer)

Unlike standard Zepbound pens, the Zepbound KwikPen contains four doses, so you’ll go through about one per month. For safety and hygiene purposes, you’ll use a new pen needle for each dose.

2. Zepbound Savings Card

If you have commercial insurance, you may be eligible for the Zepbound Savings Card from Eli Lilly, which can reduce the cost to as low as $25 for up to a three-month prescription of Zepbound pens. 

Having commercial insurance doesn’t automatically guarantee eligibility for this savings program. Importantly, the savings card is not available to people who are also enrolled in government insurance plans, such as Medicare, Medicaid, VA, or Tricare.

Other eligibility criteria include:

• You must have a valid prescription for Zepbound.

• You must be currently enrolled in a commercial drug insurance plan.

• You must be a resident of the US or Puerto Rico.

• You must be at least 18 years old.

3. Zepbound coupons and prescription discount card

Several websites also offer Zepbound coupons or pharmacy discount cards to help cash payers lower the cost of Zepbound or other prescription drugs. 

Websites offering Zepbound discounts include:

• SingleCare

• GoodRx

• BuzzRx

• WellRx

In most cases, these Zepbound discounts require you to fill your prescription at certain pharmacies. They also cannot be combined with insurance.

There are lower-cost weight loss drugs available, but none contain tirzepatide, the active ingredient in Zepbound. 

Note: Tirzepatide is a dual GLP-1/GIP medication. The combination is thought to make tirzepatide more effective for weight loss than similar GLP-1 medications, such as semaglutide. So, while generic or compounded options can support weight loss, they are not equivalent to Zepbound — they work differently.

Wegovy pill

The Wegovy pill is available at a cash price of $149–$299 per month on Ro, depending on the dose.

The Wegovy pill (semaglutide) is FDA-approved for weight loss and cardiovascular risk reduction. However, a head-to-head comparison of semaglutide and tirzepatide shows that semaglutide is generally less effective for weight loss. And oral Wegovy requires daily dosing, compared to Zepbound’s weekly schedule.

In that study, people taking Zepbound lost 6.5% more weight than those taking Wegovy over 72 weeks. It's worth noting that the comparison used the Wegovy injection, not the pill — and the injection can result in greater weight loss than the oral form. 

Foundayo

Like the Wegovy pill, Foundayo (orforglipron) is an oral GLP-1 medication that's FDA-approved for weight loss. Similar to oral Wegovy, an indirect comparison of Foundayo and Zepbound suggests that Foundayo may not drive as much weight loss.

Clinical trial data show that Foundayo resulted in about 7.5%–11.2% body weight loss over 72 weeks, whereas Zepbound resulted in 15%–21% weight loss over the same period. 

Still, Foundayo can be more affordable than Zepbound. Without insurance, Foundayo costs $149–$299 per month on Ro.

Generic liraglutide

 Liraglutide is the only FDA-approved GLP-1 generic. However, as Drs. Ajao and Rao note, it’s generally less effective for weight loss and requires daily injections (vs. weekly like tirzepatide). 

In 2025, the FDA approved a generic for Saxenda, a GLP-1 receptor agonist for weight loss. Clinical trial data show that Saxenda resulted in about 8% body weight reduction over 56 weeks, whereas Zepbound resulted in 15%–21% weight loss over 72 weeks.

Generic phentermine

“If a person really needs a weight loss medication to help achieve their weight goals, there are a few less expensive non-GLP -1 drugs,” Dr. Ajao says. That includes phentermine, an oral medication. (For those who prefer to avoid injections, oral tirzepatide is not available.) Phentermine has been shown to be effective for weight loss.

At less than $30 for a one-month supply, phentermine also costs considerably less than Zepbound.

That said, phentermine doesn’t support as much weight loss as Zepbound. Zepbound can lead to up to 21% body weight reduction over 72 weeks, while phentermine has been shown to produce about 7% weight loss over six months. 

Compounded semaglutide and tirzepatide

Compounded semaglutide and tirzepatide are neither generic nor FDA-approved options, but they can be more affordable. Compounded medications are legal only in certain circumstances, such as when the FDA-approved version is in short supply. They can also be made for patients who are allergic to an inactive ingredient in an FDA-approved medication.

Unlike FDA-approved medications, compounded medications do not go through the same review process for safety, quality, or effectiveness. Differences in ingredients or formulation could also affect their efficacy or safety.

Compounded semaglutide often contains the same active ingredient as Ozempic, Wegovy, the Wegovy pill, and Rybelsus. It’s not covered by insurance.

Get started

Is there a generic for Zepbound? No. When will Zepbound be generic? Not until around 2039. Here’s the roundup on what we know about a Zepbound generic:

• It won’t be available until brand-name Zepbound’s patents expire. And Eli Lilly has patents on Zepbound until 2039.

• It’s too early to know what generic Zepbound will cost. Zepbound retails for up to $1,086 per month, and generics are typically priced 20%-80% lower than brand-name medications.

• There are still ways to save. The Zepbound KwikPen is available as a cash-pay option on Ro, or explore savings options with Eli Lilly or pharmacy partners like SingleCare or GoodRx.

• Ask your provider about alternatives. Generic liraglutide, generic phentermine, and compounded medications are available at lower prices while you wait for generic Zepbound.
