For years, a GLP-1 for weight loss meant a weekly shot. Now there are pills too.
That's good news if needles aren't your thing. In a 2023 national poll, 44% of adults said they'd be interested in a weight-loss pill, against 23% for a routine injection.2KFFSourceKFF.

Here's how the pills and the shots compare, so you can decide which fits your life.

Which GLP-1 pills can you get?
Two pills are approved for weight loss in the U.S.: the Wegovy® pill and Foundayo™.

Do GLP-1 pills work as well as the shots?
They work well, though the weekly shots led to a little more weight loss on average in their main studies.
On the Wegovy® pill, people lost about 14% of their body weight on average over about 15 months.4The New England Journal of MedicineRandomized trial · 2025OASIS 4People lost 13.6% of their weight on the Wegovy pill, against 2.2% on placebo, over 64 weeks.307 people · 64 weeks.

04Day to day
What's it like to take a pill vs. a shot?
The biggest difference is the routine.
The Wegovy® pill is a morning ritual. You take it on an empty stomach with a little plain water, up to half a cup. Then you wait at least 30 minutes before eating, drinking or taking other pills.1U.S. Food and Drug AdministrationSourceFDA prescribing information for Wegovy® (injection and tablets), Foundayo™, Zepbound®, and Rybelsus® and Ozempic® tablets: Indications and Usage; Dosage and Administration; Drug Interactions; Clinical Studies; How Supplied, Storage and Handling.All sources
Food and other drinks get in the way of how the tablet is absorbed, so the wait matters.1U.S. Food and Drug AdministrationSourceFDA prescribing information for Wegovy® (injection and tablets), Foundayo™, Zepbound®, and Rybelsus® and Ozempic® tablets: Indications and Usage; Dosage and Administration; Drug Interactions; Clinical Studies; How Supplied, Storage and Handling.All sources
Foundayo™ is simpler: one tablet a day, with or without food.1U.S. Food and Drug AdministrationSourceFDA prescribing information for Wegovy® (injection and tablets), Foundayo™, Zepbound®, and Rybelsus® and Ozempic® tablets: Indications and Usage; Dosage and Administration; Drug Interactions; Clinical Studies; How Supplied, Storage and Handling.All sources
The shots are once a week, usually with a prefilled pen. You pick a day that suits you.
With every option, you start on a low dose and step up about once a month, which gives your body time to adjust.1U.S. Food and Drug AdministrationSourceFDA prescribing information for Wegovy® (injection and tablets), Foundayo™, Zepbound®, and Rybelsus® and Ozempic® tablets: Indications and Usage; Dosage and Administration; Drug Interactions; Clinical Studies; How Supplied, Storage and Handling.All sources
Early on, some people notice an upset stomach, with pills and shots alike. It usually settles, and your clinician can slow things down if it doesn't.
A few habits make either one easy:
Make the pill your first thing
Keep the Wegovy® pill by your bed and take it when you wake. Shower and get dressed while you wait, then it's time for coffee and breakfast.1U.S. Food and Drug AdministrationSourceFDA prescribing information for Wegovy® (injection and tablets), Foundayo™, Zepbound®, and Rybelsus® and Ozempic® tablets: Indications and Usage; Dosage and Administration; Drug Interactions; Clinical Studies; How Supplied, Storage and Handling.All sources
Pick a shot day
Choose a day of the week for your shot and set a reminder on your phone.
Store it right
Pills stay at room temperature in their bottle. Pens live in the fridge, and can stay out for a few weeks if you travel.1U.S. Food and Drug AdministrationSourceFDA prescribing information for Wegovy® (injection and tablets), Foundayo™, Zepbound®, and Rybelsus® and Ozempic® tablets: Indications and Usage; Dosage and Administration; Drug Interactions; Clinical Studies; How Supplied, Storage and Handling.All sources
Bring your medicine list
Some medicines need a timing or dose check, like a thyroid pill, so your clinician will see how yours fit.1U.S. Food and Drug AdministrationSourceFDA prescribing information for Wegovy® (injection and tablets), Foundayo™, Zepbound®, and Rybelsus® and Ozempic® tablets: Indications and Usage; Dosage and Administration; Drug Interactions; Clinical Studies; How Supplied, Storage and Handling.All sources
Have a backup for birth control
If you take birth control pills, Foundayo™ and Zepbound® call for a backup method. Use one for a month after you start and after each dose increase.1U.S. Food and Drug AdministrationSourceFDA prescribing information for Wegovy® (injection and tablets), Foundayo™, Zepbound®, and Rybelsus® and Ozempic® tablets: Indications and Usage; Dosage and Administration; Drug Interactions; Clinical Studies; How Supplied, Storage and Handling.All sources
05Cost
Are GLP-1 pills cheaper than the shots?
Usually, yes. Both pills start at $149 a month if you pay cash, and the price rises with the dose.10Novo NordiskSourceNovoCare. Wegovy® (semaglutide) self-pay prices.

So the pills stay a little cheaper than the brand-name shots at higher doses too.
Compounded semaglutide shots cost less again, from $49 to $179 a month at the programs we rank. We checked in late September and early October 2026.
Coverage depends on your plan. If you have Medicare, a program running through 2027 covers both pills and some shots for $50 a month, for people who qualify.13Centers for Medicare and Medicaid ServicesSourceMedicare.gov.

06Choosing
Should you choose a pill or a shot?
There's no single right answer. It comes down to what fits your life.
Here's how to think it through:
Needles
If you'd rather skip them, a pill is the easy pick.
Results
If you want the most weight loss on average, the shots led in studies, Zepbound® especially.
Your mornings
If they're rushed, Foundayo™ has no food rules, while the Wegovy® pill needs that 30-minute wait.
Your budget
Both pills start at $149 a month and stay cheaper than the brand-name shots at higher doses.
Other medicines
If you take pills in the morning, ask how each option fits around them.
Your clinician will look at your health and goals with you, and you can switch later if your needs change.1U.S. Food and Drug AdministrationSourceFDA prescribing information for Wegovy® (injection and tablets), Foundayo™, Zepbound®, and Rybelsus® and Ozempic® tablets: Indications and Usage; Dosage and Administration; Drug Interactions; Clinical Studies; How Supplied, Storage and Handling.All sources

Frequently asked questions.
Can I switch from a shot to a pill?
Yes, with your clinician's help.

Which is better, the Wegovy® pill or Foundayo™?
Neither is better for everyone.
In separate studies, people lost about 14% on the Wegovy® pill and about 11% on the top dose of Foundayo™.

Your clinician can help you weigh them.
Where can I get GLP-1 pills?
You'll need a prescription, from your own clinician or an online program.
You can fill it at a regular pharmacy, or through the makers' own pharmacies, which offer the cash prices above.10Novo NordiskSourceNovoCare. Wegovy® (semaglutide) self-pay prices.

What if I miss a dose?
Each one has its own rule, so check your instructions.
With the Wegovy® pill, skip the missed dose and take the next one the following day.
With Foundayo™, take it when you remember, but never two in one day.
The shots give you a few days' grace.1U.S. Food and Drug AdministrationSourceFDA prescribing information for Wegovy® (injection and tablets), Foundayo™, Zepbound®, and Rybelsus® and Ozempic® tablets: Indications and Usage; Dosage and Administration; Drug Interactions; Clinical Studies; How Supplied, Storage and Handling.All sources
Are compounded semaglutide tablets or drops the same as the Wegovy® pill?
No. Some programs offer compounded semaglutide as a tablet or drops.
It's made by a pharmacy, so it's a different product from the Wegovy® pill.
Your clinician can help you compare it with the brand-name pills and the weekly shots.
Anything sold over the counter as a "GLP-1 pill" is a supplement, not the medicine.15U.S. Food and Drug AdministrationSourceFDA. Questions and Answers on Dietary Supplements.Open the source All sources
The bottom line
GLP-1 pills give you a needle-free way to start, and the weekly shots still lead on average weight loss.
Either way, a clinician who knows your health and goals will help you choose.

Product information
- Zepbound® (tirzepatide) is a prescription-only injectable medication FDA-approved for chronic weight management in adults with obesity, or adults with overweight who have at least one weight-related medical condition. It is also approved for the treatment of moderate to severe obstructive sleep apnea in adults with obesity, and should be used in combination with a reduced-calorie diet and increased physical activity.
- Ozempic® (semaglutide) is a prescription-only injectable medication approved by the U.S. Food and Drug Administration (FDA) for the treatment of type 2 diabetes. It is not FDA-approved for weight loss; however, weight reduction has been observed in some individuals with type 2 diabetes using the medication.
- Mounjaro® (tirzepatide) is a prescription-only injectable medication FDA-approved for the treatment of type 2 diabetes. It is not FDA-approved for weight loss; however, weight reduction has been observed in some individuals using the medication.
- Wegovy® (semaglutide) is a prescription-only injectable medication FDA-approved for chronic weight management in adults with obesity, or adults with at least one weight-related medical condition, when used alongside a reduced-calorie diet and increased physical activity.
- All medications require a medical evaluation and prescription from a licensed healthcare provider. Individual results may vary.
Important safety information
- Compounded semaglutide and tirzepatide are prepared by state-licensed pharmacies and are not FDA approved. The FDA does not review their safety, effectiveness or quality, and clinical trial results for brand-name drugs do not carry over to them.
- Semaglutide and tirzepatide carry a boxed warning for a risk of thyroid C-cell tumors, based on animal studies, and are not for anyone with a personal or family history of medullary thyroid carcinoma (MTC) or MEN2, or who is pregnant. Other warnings include pancreatitis, gallbladder problems, and a higher risk of low blood sugar when combined with insulin or a sulfonylurea. The most common side effects are digestive, such as nausea, vomiting, diarrhea and constipation.
- This is a high-level summary, not a complete list. A licensed clinician will review your health history to decide whether a GLP-1 medication is right for you.
