Weight-loss medicine has changed genuinely in the last few years: the GLP-1 injections — semaglutide (Wegovy, Ozempic) and tirzepatide (Mounjaro) — produce weight loss that older drugs never approached, and they have arrived in Nigerian pharmacies. That has also made this the most hyped, most faked, and most carelessly sold category in the market.

Two facts keep the hype honest. First, these are prescription medicines for obesity or diabetes, dosed upward gradually under medical supervision — not slimming products to buy because a vendor on Instagram promises a size 8. Second, every genuine option is NAFDAC-registered and verifiable; the 'slimming teas', 'flat tummy' capsules, and imported injections with no NAFDAC number that fill social media are exactly the products this page exists to steer you away from.

Medicines are also the smaller half of the story. They work alongside food changes and activity, not instead of them — and for a large share of people, structured diet change alone remains the treatment that matters most. A clinician should confirm whether your weight, other conditions, and medicines make a GLP-1 appropriate at all.

## Signs & symptoms

- BMI in the obesity range, or overweight with type 2 diabetes, high blood pressure, or joint problems
- Weight that keeps returning after dieting — the situation GLP-1 medicines were studied in
- Snoring with daytime tiredness (possible sleep apnoea) alongside weight gain
- Rapid unexplained weight GAIN or LOSS without trying — see a doctor; that is a different problem, not a slimming question
- Considering a 'slimming' product with no NAFDAC number — treat that as the warning sign it is

## Medicines used in Nigeria

- tirzepatide (https://ogbogwu.com/drugs/tirzepatide/): Once-weekly injection (Mounjaro) — the strongest weight-loss results in trials; prescription-only, dose stepped up gradually
- semaglutide (https://ogbogwu.com/drugs/semaglutide/): Once-weekly injection (Wegovy for weight, Ozempic for diabetes) or daily tablet (Rybelsus); prescription-only
- liraglutide (https://ogbogwu.com/drugs/liraglutide/): Daily GLP-1 injection (Saxenda) — an earlier option, now mostly superseded by the weekly pens
- orlistat (https://ogbogwu.com/drugs/orlistat/): Oral capsule (Reeshape, Orlifit) that blocks fat absorption — modest effect, works only with a low-fat diet
- metformin (https://ogbogwu.com/drugs/metformin/): Not a weight-loss drug — but the diabetes medicine often started alongside weight management in type 2 diabetes

## How it's treated

The GLP-1 injections (Mounjaro, Wegovy, Ozempic, Saxenda) are once-weekly or once-daily pens started at a low dose and increased stepwise over months to limit nausea. They are prescription-only: a clinician should confirm the indication, screen for conditions like pancreatitis history, and plan follow-up. Expect gastrointestinal side effects early, and expect weight to return if the medicine is stopped without habits changing.

Orlistat (Reeshape, Orlifit) is the older oral option: it blocks about a third of dietary fat from being absorbed, works only alongside a reduced-fat diet, and announces any high-fat meal with oily stools. Modest but real, and far cheaper than GLP-1s. Whatever the medicine, the foundation is the same — fewer refined calories, more movement, and patience measured in months.

## See a doctor if

- Before starting any GLP-1 injection — these need a prescription, dose planning, and follow-up
- Severe or persistent abdominal pain on a GLP-1 — pancreatitis must be ruled out urgently
- Vomiting that prevents keeping fluids down, or signs of gallbladder trouble (pain after fatty food, yellowed eyes)
- Rapid weight change you did not work for, night sweats, or a lump — that is not a slimming problem
- A history of thyroid cancer in the family, pregnancy, or planning pregnancy — GLP-1s are not for you right now

## Prevention

- Buy GLP-1 pens only from a licensed pharmacy, cold-chain intact, and verify the NAFDAC number — this is now among the most-faked expensive medicines in the world
- No NAFDAC number means no purchase: 'slimming teas', 'flat tummy' gummies, and imported injections without registration are unverifiable and sometimes laced
- Be suspicious of prices far below the market — a genuine Mounjaro or Wegovy pen is expensive everywhere; a cheap one is a fake
- Plan the exit before the entry: agree with your clinician what happens after the target weight, because unplanned stopping usually means regain

## FAQs

### What is the best drug for weight loss in Nigeria?

For most people who qualify medically, tirzepatide (Mounjaro) has shown the largest average weight loss in trials, with semaglutide (Wegovy) close behind — both are NAFDAC-verifiable, prescription-only weekly injections. Orlistat (Reeshape, Orlifit) is the affordable oral option with a more modest effect. 'Best' depends on your health, budget, and a clinician's assessment — and no tea, gummy, or unregistered injection belongs on the list at all.

### How much do Mounjaro, Wegovy and Ozempic cost in Nigeria?

Prices move with the naira and the dose, so check current pharmacy prices — each brand's page here carries what we know. As a rule the GLP-1 pens cost hundreds of thousands of naira per month, which is exactly why heavily discounted pens on social media should be treated as counterfeit until verified. Check the NAFDAC number and buy from a licensed pharmacy that stores them refrigerated.

### Are slimming teas and 'flat tummy' products approved by NAFDAC?

Some herbal slimming products hold NAFDAC listings (a lighter recognition than medicine registration), but many sold online carry no number at all — and unregistered products have repeatedly been found adulterated with hidden drugs like sibutramine, which was withdrawn worldwide for heart risks. If a slimming product has no NAFDAC number on the pack, or the number doesn't check out in our checker, don't swallow it.

### Will I regain weight after stopping Mounjaro or Wegovy?

Without changed habits, usually yes — trials show much of the lost weight returns within a year of stopping. These medicines manage appetite while you use them; they are not a cure. The people who keep the loss are the ones who used the medicine as a window to rebuild eating and activity patterns, and who planned the stop with their clinician rather than simply running out.
