Weight Loss Pills in 2026: Which Ones Work and What They Cost

Yes, the prescription ones do, and the best of them now rival injections. Two GLP-1 medicines, from the same drug class as Ozempic, Wegovy and Zepbound, are FDA-approved as once-daily tablets for chronic weight management:

• The Wegovy pill (oral semaglutide 25 mg, Novo Nordisk), approved in December 2025, averaged 13.6% weight loss in its trial. Its trial authors describe that result as similar to the weekly semaglutide injection.
• Foundayo (orforglipron, Eli Lilly), approved on April 1, 2026, averaged 11.2%.

The older prescription pills are still prescribed. They make sense for people who cannot take a GLP-1, cannot afford one, or need less weight loss than a GLP-1 delivers.

Ranked by the strength of their evidence, the options fall into four groups, and this guide covers them in this order:

1. FDA-approved GLP-1 pills: the Wegovy pill and Foundayo. Rybelsus belongs to the same family but is semaglutide at diabetes doses with no weight-loss approval.
2. Older FDA-approved prescription pills: Qsymia, Contrave, phentermine and orlistat, averaging roughly 3-10% weight loss, each with people who must avoid it.
3. Compounded oral semaglutide and tirzepatide: offered by some telehealth programs, legal under certain conditions, not FDA-approved and never tested in their own trials.
4. Over-the-counter "diet pills": the group in which the FDA keeps finding hidden, banned drugs.

The GLP-1 tablets contain the same class of medicine as the weekly injections, taken by mouth instead. Trial figures in the table are the published New England Journal of Medicine results, which count every randomized participant. The manufacturers also cite higher on-treatment figures (16.6% for the Wegovy pill, 12.4% for Foundayo) that only include people who kept taking the pill as directed. Ro's prices are its own published figures, verified by us; manufacturer prices are as reported by the sources linked in the cost section.

How the Wegovy pill works and how you take it

The Wegovy pill delivers semaglutide, a peptide, and the gut absorbs peptides poorly. That explains two things: the tablet holds 25 mg of semaglutide compared with 2.4 mg a week in the injection, and it comes with a strict routine. You swallow it on an empty stomach with a small sip of water and then wait about 30 minutes before eating, drinking or taking other medicines; skipping the wait reduces how much drug gets absorbed. Treatment starts at a 1.5 mg tablet and steps up over several months to the 25 mg maintenance dose tested in the trial. The approval covers reducing and keeping off excess weight in adults with obesity, or with overweight plus a weight-related condition, and lowering cardiovascular risk in the same group. For every way to buy it, see Wegovy pill price online.

Why Foundayo has no timing rules

Foundayo's active ingredient, orforglipron, is a small molecule rather than a peptide, so it is absorbed like most everyday tablets. As a result you can take it at any hour, with or without food or water, moving up through 6 mg, 12 mg and 36 mg tablets. Its average result is lower than the Wegovy pill's, but the two drugs were studied in separate trials of different lengths and have never been compared directly. Foundayo's strongest selling point is convenience for people who take other morning medicines, want coffee as soon as they wake, or will not stick to a timed routine. Our Foundayo vs Wegovy pill comparison goes through the differences in detail.

Why Rybelsus is not a weight loss pill

Rybelsus contains the same semaglutide as the Wegovy pill, but at 7 mg and 14 mg, and it is approved for type 2 diabetes. Weight does come down on it, yet the doses are far lower than the 25 mg weight-management tablet, the empty-stomach rule still applies, and insurers will not cover it for weight loss because that use is not on its label. Being offered Rybelsus "for weight loss" means being offered an off-label diabetes medicine when an approved weight-loss version of the same molecule is available.

Almost, but not quite. Injections still produce the highest average weight loss. The Wegovy pill matched semaglutide injections in its own trial, and Foundayo trades a few points of effect for no needle and no timing rules.

The format does not change the side effects. Pills and injections share the same digestive side effects, which mostly show up early and after dose increases, and carry the same class warnings. For year-one costs and a closer look at each routine, read GLP-1 pills vs injections.

The older prescription pills produce less weight loss than the GLP-1 tablets but usually cost far less, since most are available as generics. They were the main prescription options before GLP-1s arrived and are still written every day. Each works differently: some curb appetite, one targets cravings, and one blocks fat absorption. The NIDDK overview of prescription medicines for overweight and obesity lists each with its approval. The typical results below are approximate ranges, and individual responses vary a lot.

Qsymia (phentermine/topiramate)

Qsymia pairs phentermine with extended-release topiramate, a medicine for seizures and migraine that also lowers appetite. It is prescribed together with a reduced-calorie diet and exercise for adults, and for children 12 and older, who have obesity or overweight with a weight-related condition. According to the MedlinePlus drug information, it starts at a low dose, increases after 14 days, and is reassessed at 12 weeks, when the clinician decides to continue, raise the dose or stop. Topiramate sets the strict rules: because it can cause birth defects, a negative pregnancy test is needed before starting and reliable contraception throughout, and glaucoma and an overactive thyroid rule it out. By the published figures, Qsymia is the strongest of the older pills.

Contrave (naltrexone/bupropion)

Contrave combines naltrexone, which blocks opioids, with bupropion, an antidepressant also used to help people quit smoking. The MedlinePlus drug information leads with its boxed warning: in studies, bupropion was associated with suicidal thoughts in a small number of young people, so anyone taking it should be monitored for mood changes. It cannot be used with opioids, because naltrexone blocks them and can set off withdrawal, by people with seizure disorders or uncontrolled high blood pressure, or within 14 days of an MAO inhibitor. For a suitable patient, often someone who eats in response to cravings more than hunger, Contrave is a sensible option.

Phentermine

Phentermine is the oldest medicine here and remains the most prescribed. It is a stimulant-like appetite suppressant and a controlled substance, approved for short-term use lasting weeks, with cautions for heart disease, high blood pressure, overactive thyroid, glaucoma and MAO inhibitors. The generic is cheap and it works while you are taking it, but weight usually comes back once the course ends. That is why clinicians now tend to use phentermine as a short kick-start rather than a long-term plan.

Orlistat (Xenical and Alli)

Orlistat acts in the digestive tract instead of the brain. It blocks the enzyme that breaks down fat, so some of the fat in each meal passes through without being absorbed. Xenical is the 120 mg prescription strength, and Alli, at 60 mg, is the only over-the-counter weight-loss medicine with FDA approval. Its side effects come straight from how it works: oily stools, urgency and gas, all worse after high-fat meals, which tends to push people toward eating less fat. Because it also reduces absorption of fat-soluble vitamins, a daily multivitamin taken at a different time from the dose is the usual advice.

Metformin

Metformin is a type 2 diabetes medicine that some clinicians prescribe off-label for weight, especially when insulin resistance or prediabetes is present. Its effect on weight is small and it has no FDA approval for weight loss. It appears here because it is inexpensive, well known and often the first option a primary-care doctor tries, not because it can replace any of the medicines above when the aim is substantial weight loss.

GLP-1 pills cost $149-$349 a month self-pay as reported, $25 with commercial coverage and $50 on Medicare's pilot; the older pills are mostly cheap generics. The GLP-1 tablets are new brand-name drugs with brand-name pricing, and savings cards or Medicare's pilot can change what you pay completely. We do not list prices for the older generic pills because they vary by pharmacy and plan; a pharmacist can quote you the cash price quickly. Ro's figures below are its own published prices, verified by us in August 2026. Manufacturer prices come from the dated sources linked and have not been verified by us.

The Medicare GLP-1 Bridge is a CMS pilot that runs from July 1, 2026 through December 31, 2027. It covers the Wegovy pill and injection, the Zepbound KwikPen and Foundayo at $50 a month at any dose, with eligibility and approval handled by your Part D plan. Neither manufacturer savings card can be used with Medicare or Medicaid.

For comparison, at the providers we track, compounded semaglutide injections cost $49-$199 a month and compounded tirzepatide $89-$299, verified on each provider's site on October 16, 2026. If you are paying cash and dislike needles, read what $100-$200 a month gets you before deciding a pill is worth the extra cost. To check your formulary first, use our insurance guide, and for Medicare questions see GLP-1s after 65.

No. Compounded oral semaglutide and tirzepatide are not FDA-approved and have never been tested in their own trials. Several telehealth providers sell them as tablets, under-the-tongue drops or dissolving films next to their injections, and some simply call them "the pill". Licensed 503A compounding pharmacies make them for individual prescriptions under the rules the FDA describes on its human drug compounding page. That channel is legal and regulated, but the products differ from the approved tablets in three ways:

• No FDA approval. Compounded products do not go through pre-market review.
• No trials of their own. There is no published evidence of how much weight they produce.
• Different absorption. An oral compounded peptide is absorbed differently from the approved 25 mg tablet, which needed specific formulation work to survive the stomach.

The FDA's statement on unapproved GLP-1 drugs lists its concerns: no pre-market check of safety, effectiveness or quality; adverse-event reports that include dosing mistakes; and products containing salt forms of semaglutide that are not the approved active ingredient.

Their appeal is a lower price and an existing relationship with a provider. Put plainly, choosing a compounded oral product means trusting that the pharmacy's formulation delivers enough medicine, without published evidence that it does. If you want a pill backed by data, choose one of the two approved pills. If price is the deciding factor and an injection is acceptable, compounded injections use the same molecules and have far more real-world use. We cover the trade-offs in compounded vs brand-name and the 503A vs 503B explainer. A licensed clinician reviews your health profile and decides between oral and injectable options, with no in-person visit required.

Mostly no: over-the-counter diet pills are largely unproven, and some contain hidden prescription drugs. Fat burners, appetite "blockers", herbal blends and detox teas rarely have solid evidence behind them, and they are not regulated like prescription medicines. Doing nothing is not the only risk. FDA testing of weight-loss supplements sold online and in stores has repeatedly turned up undeclared prescription drugs, most often sibutramine, a weight-loss medicine withdrawn from the US market in 2010 because it raised blood pressure and heart rate and increased cardiovascular risk. The February 2023 FDA notice on Alfia Weight Loss Capsules is one entry in a long list, and the FDA has said it cannot test every product sold, so a product missing from that list is not proof it is safe.

Orlistat 60 mg (Alli), covered above, is the only over-the-counter weight-loss product with FDA approval. Treat everything else sold for weight loss without a prescription as unproven at best. For real results, the evidence points to a licensed clinician and an FDA-approved medicine, and every option on this page apart from Alli needs a prescription.

Every weight loss pill has people who must not take it, and a legitimate provider's intake form is designed to identify them. The firm exclusions from the labels:

• Pregnancy and breastfeeding. None of these medicines is used during pregnancy. Qsymia is the strictest, because topiramate causes birth defects: it requires a pregnancy test before starting and reliable contraception for the whole course.
• GLP-1 pills (Wegovy pill, Foundayo, Rybelsus). Contraindicated with a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2; carry warnings on pancreatitis and gallbladder disease. The Wegovy pill's absorption rule means other morning medicines may need to move.
• Qsymia. Not with glaucoma, an overactive thyroid, or within 14 days of an MAO inhibitor; topiramate can also affect mood and memory and raise the risk of kidney stones.
• Contrave. Not with any opioid use, seizure disorders, uncontrolled high blood pressure, a history of eating disorders, sudden withdrawal from alcohol or sedatives, or MAO inhibitors; its boxed warning on suicidal thoughts applies to everyone who starts it.
• Phentermine. Not with heart disease, uncontrolled high blood pressure, an overactive thyroid, glaucoma, a history of drug misuse, or MAO inhibitors.
• Orlistat. Not with chronic malabsorption or gallbladder problems; it also alters absorption of some other medicines, including thyroid hormone and certain anticoagulants, which need to be spaced apart.

Two broader points apply to all of them. First, each is a prescription medicine within a treatment plan, not a simple purchase, and the prescribing clinician also handles side effects and decides when to stop. Second, weight tends to come back after stopping: in the GLP-1 extension studies, about two-thirds of the weight lost was regained within a year of stopping semaglutide, and the older pills follow the same pattern in practice. The practical question is which option you can keep up.

The right pill depends on your coverage, budget and health history. Most readers match one of these situations:

Your insurance covers a GLP-1 and you want the strongest pill. Pick the Wegovy pill or Foundayo, whichever your plan covers, at a reported $25 a month with the savings card. The Wegovy pill has the bigger trial result; Foundayo has no timing rules.

You have Medicare. Ask your Part D plan about the GLP-1 Bridge, which covers both pills at a flat $50 that does not rise with the dose. Decide on routine and results rather than price.

You want a GLP-1 pill and will pay cash. Ro is the telehealth route for the Wegovy pill we have verified, at $149 and then $299 plus membership. For Foundayo, the reference is LillyDirect's reported $149-$349. Plan around the maintenance-dose price rather than month one, and do not accept a compounded "pill" in place of an approved one.

You cannot take a GLP-1, or you need less weight loss. Qsymia is the strongest older pill and Contrave suits eating driven by cravings. Both are long-term options with specific exclusions, and a clinician who knows your history picks between them.

You want the lowest cost with evidence behind it. Consider generic phentermine for a short start, or orlistat; both are inexpensive at a pharmacy. If a weekly injection is acceptable, compounded semaglutide starts at $49 a month and produces much more weight loss than any older pill. Our provider comparison lists every verified compounded price.

You were about to buy an over-the-counter product. Read the FDA section above first. Alli is the only one with an approval; with the rest you are gambling on what is inside as well as on results.

In every case, the prescriber decides based on your history rather than a table, and may decline to prescribe any of these.

You complete an online intake, a licensed clinician reviews it, and if a prescription is appropriate the medicine is shipped to you or sent to your pharmacy. The steps are the same for every prescription option:

1. Fill in an online intake covering your weight, health history, current medicines and goals.
2. A licensed clinician reviews it.
3. If appropriate, you receive a prescription, filled by the provider's partner pharmacy and shipped to you, or sent to a pharmacy you choose when insurance applies.
4. Follow-up continues as the dose increases, or at the 12-week check the older pills' labels require.

For the FDA-approved Wegovy pill, Ro is the provider we have verified. For compounded oral or injectable semaglutide and tirzepatide, every provider below and on our comparison requires a clinician review before prescribing. Our complete guide to GLP-1 weight loss online covers each step, including how to check the pharmacy and the refund terms if you are not approved.

This guide offers general information and is not medical advice. Prescription weight loss medicines need assessment and supervision by a licensed healthcare provider, who decides whether any of them suits you.
