Weight loss pills in South Africa: what works in 2026

Which weight loss pills are registered in South Africa?

Three tablet medicines hold SAHPRA registration for weight loss. Orlistat, sold as Xenical, and naltrexone/bupropion, sold as Contrave, are registered for long-term weight management; the 2025 South African obesity guideline lists both among the four medicines it covers. Phentermine, sold as Duromine, is registered for short-term use only.

All three are scheduled medicines. Orlistat is Schedule 3 and phentermine Schedule 5, so a doctor's assessment and authorisation comes before a pharmacy may dispense them, and none of them lawfully sits on an open shelf next to the vitamins.

GLP-1 tablets are missing from the table for a reason: none is registered in South Africa yet, a gap this guide returns to below.

How does orlistat work?

Orlistat blocks fat digestion rather than appetite. It inhibits pancreatic lipase, the enzyme that breaks down dietary fat, so roughly a quarter of the fat you eat passes through the gut undigested instead of being absorbed. The dose is one 120 mg capsule with each of the day's three meals, and it only works in the presence of dietary fat.

The trial record is modest and clear: a mean placebo-subtracted weight loss of 2.9% at one year in the South African guideline's summary, and individual results vary. Treatment carries a built-in checkpoint too. If you have not lost at least 5% of your body weight after 12 weeks, the doctor stops the treatment.

Side effects follow directly from the mechanism. Undigested fat has to leave the body, so oily spotting, loose stools, urgency and wind with discharge are the common complaints, and they get worse after high-fat meals. Orlistat also reduces absorption of the fat-soluble vitamins A, D, E and K, which is why doctors usually add a multivitamin taken at least two hours away from a dose.

It is ruled out by chronic malabsorption syndrome and cholestasis, not recommended in pregnancy, and not used while breastfeeding, and it can interfere with warfarin, ciclosporin and antiepileptic medicines. The full picture, including who tends to do well on it, is in our guide to orlistat in South Africa.

What about alli, the 60 mg orlistat brand?

alli is orlistat at half strength: 60 mg per capsule against Xenical's 120 mg. It is the same molecule working the same way, dosed lower, and in the United States and parts of Europe that lower dose is sold over the counter under pharmacist supervision rather than through a doctor.

South African searches for alli mostly surface import listings on international websites. A parcel from one of those listings sits outside the South African system entirely: SAHPRA has evaluated neither the product nor the seller, and nobody local answers for what arrives. A pharmacist at any licensed pharmacy can tell you in one conversation which orlistat products are actually stocked here, and at which strength.

Half the dose also does not mean none of the cautions. The fat-related side effects, the vitamin interaction and the exclusions above apply to orlistat at any strength, so the conversation with a pharmacist or doctor stays worth having even where the lower dose is sold without one.

Where does Duromine fit among weight loss pills?

Duromine is phentermine, an appetite suppressant registered in South Africa for short-term use only, ideally no longer than three months. It is a Schedule 5 medicine taken as one capsule in the morning, and it works on the brain's appetite centres rather than in the gut, which makes it the odd one out on this list.

The three-month limit is a safety boundary, not paperwork. Duromine's registered information calls for medical review after each course, because treatment with appetite suppressants of this kind beyond three months significantly increases the risk of primary pulmonary hypertension, a rare but serious lung condition.

The exclusion list is long and mostly cardiovascular. High blood pressure, heart disease, hyperthyroidism, glaucoma, a history of psychiatric illness including anorexia and depression, and any history of alcohol or drug dependence all rule it out, and it is not used in pregnancy. It can disturb sleep, which is why the dose is taken early in the day, and it must never be combined with other appetite suppressants.

Those boundaries define where Duromine fits in 2026: a short, supervised tool for a specific situation, not a treatment for a chronic condition. How it stacks up against the class now registered for long-term use is covered in Duromine vs GLP-1.

What is naltrexone/bupropion and who suits it?

Naltrexone/bupropion, sold as Contrave, combines two older medicines into a single weight management tablet registered for long-term use in South Africa. It works on appetite and reward pathways in the brain, and in trial data reported by the South African guideline, patients lost 6.1% of body weight over a year against 1.3% on placebo. Individual results vary.

Dosing builds up gradually: one tablet daily in the first week, adding a tablet each week until the maintenance dose of two tablets twice daily. The slow build exists because nausea is the most common side effect, alongside constipation, headache, vomiting, insomnia, dry mouth and dizziness.

The exclusions come from both ingredients. Bupropion rules out anyone with a seizure disorder or an eating disorder such as anorexia or bulimia. Naltrexone makes any opioid use an absolute contraindication, which includes codeine, the opioid in many South African painkillers. Uncontrolled high blood pressure excludes the combination outright.

That screening burden is exactly why this medicine runs through a doctor. A tablet that clashes with epilepsy, opioids and raised blood pressure is safe for many people and wrong for others, and the sorting happens in an assessment, not at a till.

Is there a GLP-1 weight loss pill in South Africa?

No. No GLP-1 pill is registered for weight loss in South Africa. The GLP-1 tablets in international headlines, the Wegovy pill and orforglipron, are approved in the United States and elsewhere, but neither holds a SAHPRA registration, and neither company has announced a local launch date.

The pipeline itself is real. The US FDA approved the Wegovy pill, oral semaglutide 25 mg, in December 2025 and the European Union followed in July 2026; the full story sits in our guide to the Wegovy pill. Eli Lilly's orforglipron, a once-daily tablet the FDA approved in April 2026, has been filed in more than 40 countries, and orforglipron's South African outlook covers what that could mean here.

Two details keep the local picture straight. Rybelsus, the original semaglutide tablet, was registered by SAHPRA in 2024 for type 2 diabetes, not weight loss, and has never been launched here. Ozempic, the injectable most people know by name, is also registered for type 2 diabetes, not weight management.

Until a registration lands, anything sold in South Africa as a GLP-1 pill, capsule or drop is an unregistered product, whatever the advert says. A November 2025 SAHPRA warning described sellers falsely claiming affiliation with major pharmacy chains and displaying the regulator's own logo on their packs. No legal GLP-1 tablet exists on any South African shelf in 2026.

How do weight loss pills compare with injections?

On trial results, the registered pills sit below the injectable medicines. The South African guideline's one-year figures run from 2.9% placebo-subtracted weight loss for orlistat up to 14.9% at 68 weeks for semaglutide 2.4 mg, with both tablets at the lower end of the range. Individual results vary.

Those figures come from separate trials with different designs, not head-to-head contests, and they describe averages rather than promises. Tolerability, cost, daily routine and your medical history all weigh in alongside the percentages.

The numbers also do not make tablets obsolete. A pill needs no fridge and no injection technique, and orlistat in particular works in the gut without touching the heart or brain, which matters for people the other medicines exclude. The injectable half of this comparison is covered in weight loss injections in South Africa, and the right option is decided by a doctor on assessment.

Do over-the-counter slimming supplements work?

No slimming supplement sold in South Africa carries a SAHPRA weight management registration, and none has produced trial evidence in the league of the registered medicines. Supplements reach shelves without the efficacy testing that medicine registration demands, so a weight loss claim on a supplement label is a claim nobody has verified.

The difference is the bar each product had to clear. A registered medicine proves efficacy, safety and manufacturing quality to SAHPRA before it is sold, and its claims stay within what the evidence showed. A supplement clears no such bar, which is how the same pharmacy can hold a Schedule 3 medicine behind the counter and an unproven slimming capsule in the front aisle.

The 2025 South African obesity guideline is direct on this point: it advises against using any weight loss product, over the counter or otherwise, beyond the medicines approved in South Africa.

The riskiest corner of the unregistered market borrows medical names. GLP-1 drops, semaglutide capsules and slimming injections sold through social media are unregistered products with unverified contents, and SAHPRA's warnings cover them directly. Our guide to compounded GLP-1 products in South Africa explains the seizures and recalls that followed in 2026.

How do you check whether a weight loss pill is a registered medicine?

Look for a SAHPRA registration number on the packaging: every registered medicine carries one, and no supplement does. A pharmacist at any licensed pharmacy can confirm a product's status in minutes. If a seller cannot point to a registration number, you are not looking at a registered medicine.

1. Check the pack for a SAHPRA registration number, and ask a pharmacist to confirm it if anything looks off.
2. Check the seller. Registered weight loss tablets reach patients through licensed pharmacies, and the South African Pharmacy Council's public register lists every one.
3. Treat social media sellers with care: SAHPRA has warned about sellers faking ties to major pharmacy chains and using its logo without permission.
4. Report a suspicious product or seller to SAHPRA's 24-hour hotline on 0800 204 307.

The route matters as much as the pack. Registered weight loss tablets are scheduled medicines, so the lawful path runs through a doctor's assessment and authorisation and then a licensed pharmacy. A checkout page with no doctor anywhere in the process is operating outside that system, whatever is inside the bottle.

What do weight loss pills cost compared with injections?

Tablet prices are regulated the same way as every medicine price in South Africa: the Single Exit Price system sets one national price per product, every pharmacy charges it, and a regulated dispensing fee goes on top. You can look up the current price of any registered product on the Department of Health's Medicine Price Registry at mpr.gov.za.

This guide quotes no rand figures for the tablets because the registry is always more current than an article, and published prices move within an annual adjustment cycle. We do not sell medicine. Prices vary by pharmacy and dose; confirm with your pharmacy.

The medicine is also never the whole budget. A doctor's assessment, follow-up reviews and any baseline blood tests are billed separately by the practice and the laboratory, whichever tablet or injection ends up in the plan.

Who should consider weight loss medicine at all?

South African guidance supports weight loss medicine for adults with a BMI of 30 or more, or 27 or more alongside a weight-related condition such as high blood pressure or type 2 diabetes. Below those thresholds medicine is not indicated, and eating and activity changes are the plan rather than the foundation of one.

Two guideline findings set realistic expectations. Healthy behaviour changes alone typically deliver 3 to 5% weight loss, meaningful but hard to hold over years. And trials across the medicines on this page consistently show weight returning when treatment stops, which is why doctors treat obesity as a chronic condition rather than a short project. That framing is unpacked in our guide to obesity.

Supervision is the constant across every option. Each registered tablet carries exclusions serious enough that no stranger should be selling it to you, which is exactly what the medicine schedules enforce: a doctor checks blood pressure, current medicines, mental health history and pregnancy plans before any of them is appropriate.

How does a doctor choose between the options?

By elimination first, then by fit. The exclusion lists do the early sorting: opioid painkillers rule out naltrexone/bupropion, heart disease and high blood pressure rule out phentermine, a malabsorption disorder rules out orlistat. Whatever remains is weighed against your goals, your routine, your budget and how you tolerate each medicine's side effects.

Registration length belongs in that weighing. Phentermine's three-month limit makes it a start rather than a plan, orlistat and naltrexone/bupropion are registered for ongoing use, and the injectable class holds the strongest long-term trial data. None of that ranks the options for you personally, and the right option is decided by a doctor on assessment.

If tablets and injections are both on your shortlist, the assessment is where the comparison becomes concrete. How our process works describes what a doctor-led review involves; wherever you have one done, arrive with your medicine list, your health history and a clear sense of the routine you can keep.
