Without insurance, FDA-approved weight loss injections cost roughly $1,000 to $1,300 per month at retail, which works out to about $8,100 to $15,700 a year depending on the medication. Tirzepatide (Zepbound) is currently the least expensive of the injectables at around $1,000 a month, while semaglutide (Wegovy) runs closer to $1,300. Manufacturer discounts, assistance programs, and lower-cost oral medications can bring those numbers down considerably. Prices change often and vary by pharmacy and location, so treat these as approximate figures rather than fixed quotes.
This guide breaks down what each injection costs without insurance, the ways to pay less, how insurance and Medicare coverage works, and the cheaper alternatives worth knowing about. Everything here is educational and not a substitute for advice from a licensed healthcare provider.
The injectable medications people ask about most are the GLP-1 and dual GIP/GLP-1 drugs. The retail prices below are without insurance, and they are approximate, varying by pharmacy and changing over time.
| Medication | Dosing | Approx. monthly retail | Approx. annual retail |
| Wegovy (semaglutide) | Weekly injection | About $1,300 | About $14,000 |
| Zepbound (tirzepatide) | Weekly injection | About $1,000 | About $8,100 to $12,700 |
| Saxenda (liraglutide) | Daily injection | About $1,050 to $1,300 | About $15,700 |
As the table shows, all three sit in a similar range, but they are not equal in value. The differences in effectiveness matter as much as the sticker price, which is where the cost comparison gets more interesting.
Keep in mind that the cash price you see advertised is not always what you end up paying, and it is not always what a structured program charges either. Retail pharmacy prices, manufacturer cash-pay programs, and telehealth services can all differ, sometimes substantially, for the very same medication. That is why two people can pay very different amounts for the same drug. It also means the most useful number is not the headline retail price but the price you can actually access through whatever route fits your situation, which often takes a quick conversation to pin down.
Zepbound (tirzepatide). At about $1,000 a month, tirzepatide is currently the least expensive injectable GLP-1-based obesity medication, and it also produced the greatest weight loss in trials (around 20.9 percent at the highest dose). That combination makes it the strongest value per pound lost among the injectables for many people.
Wegovy (semaglutide). Semaglutide carries a retail price of around $1,300 a month, with an average list price per fill reported near $959 by Medicare. It produced about 14.9 percent average weight loss in trials, so it is highly effective, just typically pricier than tirzepatide.
Saxenda (liraglutide). Liraglutide costs roughly $1,050 to $1,300 a month but is a daily injection and produces less weight loss (around 8 percent from baseline). Because the price is similar to the more effective options while the results are smaller, it tends to be the least cost-effective choice per percentage of body weight lost.
The retail price is rarely the final price. Several routes can reduce what you actually pay:
One option to approach with caution is compounded GLP-1 preparations, which have been marketed at a lower cost (roughly $1,800 to $3,000 a year). These are not FDA-regulated for safety or effectiveness, and recent FDA guidance has aimed to curtail their production, so they carry uncertainty that the approved products do not. Discuss any compounded option carefully with a provider before considering it.

Coverage is the biggest variable in what you will actually pay, and unfortunately it is often a barrier. Many commercial insurance plans do not cover medications prescribed for weight loss alone. Medicare Part D does not cover GLP-1 medications for obesity by itself; coverage is limited to people who also have a qualifying condition such as type 2 diabetes or established cardiovascular disease.
Even when a plan does cover these medications, prior authorization is now nearly universal, required in essentially 100 percent of covered cases, which means your provider has to submit paperwork justifying the prescription before it is approved. Because coverage rules vary so much, it is worth checking your specific plan's formulary and requirements. A provider's office or a telehealth program can often help navigate this process and identify the most affordable path for your situation.
If your plan does not cover the medication, that is not the end of the road. Many people pay cash using a combination of a manufacturer savings card and a lower-priced supply channel, and some find that the all-in cost through a telehealth program is more predictable than juggling pharmacy prices and coverage denials on their own. The key is to compare the real, after-discount price across the routes available to you rather than assuming the retail figure is what you will pay.

If the injectables are out of reach, oral weight loss medications are substantially less expensive, though they generally produce less weight loss than the GLP-1-based injections:
Newer oral GLP-1 options are also emerging, including a daily semaglutide tablet, which expands the choices for people who prefer pills or want to manage cost. The right balance of price and effectiveness depends on your goals, your health, and what you can sustain, which is a conversation to have with a provider.
It is worth being realistic about the trade-off, though. The cheaper oral options generally produce less weight loss than the GLP-1 injections, so the lowest price is not automatically the best value. A medication that costs less per month but delivers a fraction of the result may end up being a poorer investment than a pricier option that actually reaches your goal. The aim is to find the most effective option you can afford and stay on consistently, rather than simply the cheapest item on the list.
Weight loss injections are a significant expense, and whether they are worth it is a personal decision that depends on your health, your goals, and your budget. What the evidence makes clear is that, dollar for dollar, the injectables deliver far greater and more reliable weight loss than over-the-counter supplements or fat burner products, which cost money while producing little to no meaningful result.
For people with obesity or overweight with a weight-related condition, these medications can also improve health markers beyond weight, which factors into their value. Because cost, coverage, and the right medication all vary by individual, the most practical first step is a medical evaluation that clarifies your options and the most affordable way to access them. Individual results vary, and a provider can help you weigh the costs and benefits for your situation.
It also helps to think about the cost over a realistic time frame rather than month to month. Because these are long-term treatments and weight tends to return after stopping, the relevant question is what an ongoing plan costs and whether it is sustainable for you, not just what a single month costs. Budgeting for the medication the way you would for any recurring health expense, and using the discount routes above, often makes the difference between starting something you can stick with and starting something you have to abandon. A provider or program can help you map out that longer-term picture before you begin.

How much do weight loss injections cost per month without insurance?
Roughly $1,000 to $1,300 a month at retail. Tirzepatide (Zepbound) is about $1,000, semaglutide (Wegovy) about $1,300, and liraglutide (Saxenda) about $1,050 to $1,300. Prices vary by pharmacy and change over time.
Which weight loss injection is the cheapest?
Among the injectables, tirzepatide (Zepbound) is currently the least expensive at around $1,000 a month, and it also produced the greatest weight loss in trials, making it a strong value. Oral medications like phentermine are far cheaper but less effective.
Does insurance cover weight loss injections?
Often not for weight loss alone. Many commercial plans exclude them, and Medicare Part D covers GLP-1 medications only when there is a qualifying condition like type 2 diabetes or heart disease. When covered, prior authorization is almost always required.
How can I lower the cost?
Manufacturer savings cards can reduce costs to roughly $580 to $670 a month for eligible patients, and patient assistance programs help those with financial need. Resources like NeedyMeds and RxAssist list available programs. Oral medications are a lower-cost alternative.
Are compounded versions a safe way to save money?
Compounded GLP-1 products can be cheaper but are not FDA-regulated for safety or effectiveness, and recent FDA guidance has aimed to limit them. Discuss any compounded option carefully with a healthcare provider before considering it.
