## Price in Nigeria

We quote no naira figure for semaglutide because our sampled online listings hold none that are stable: Ozempic, Wegovy and Rybelsus are specialty imports moving through a handful of registered channels, with cost driven by dose strength, pen count and the exchange rate — and the shortage-and-hype market around them is exactly where fakes concentrate. Confirm the NAFDAC registration on any pack before paying, buy only from licensed pharmacies, or tell us what you need and we'll connect you with a verified source.

## What is Semaglutide?

Semaglutide is a GLP-1 receptor agonist — the class of medicines behind the global surge in interest around Ozempic, Wegovy, and Rybelsus. It was developed for type-2 diabetes, where it lowers blood sugar, but it also powerfully reduces appetite and body weight, which is why it has become one of the most sought-after (and most talked-about) drugs in Nigeria's cities. It is made by Novo Nordisk and sold as Ozempic (a once-weekly injection for diabetes), Rybelsus (a daily tablet for diabetes), and Wegovy (a higher-dose weekly injection licensed specifically for weight loss).

Semaglutide works by mimicking GLP-1, a natural gut hormone released after eating. It tells the pancreas to release insulin when blood sugar is high, slows how quickly the stomach empties, and acts on the brain's appetite centres so you feel full sooner and eat less. In type-2 diabetes this brings blood sugar down and often causes weight loss too; used for obesity, that appetite effect is the main point. It is a prescription-only medicine that should be started and monitored by a doctor, usually beginning at a low dose that is increased slowly to limit nausea.

In Nigeria, three things matter enormously before anyone considers semaglutide. First, it is expensive and largely imported, so prices run into the hundreds of thousands of naira and swing sharply with the exchange rate and supply. Second, the injections must be kept cold (refrigerated) — a broken cold chain ruins the medicine. Third, and most important, the huge demand has driven a wave of counterfeit and improperly stored 'Ozempic' and 'Wegovy' pens; a price that looks too good to be true almost always means a fake. Always insist on a licensed pharmacy and verify the product, and remember this is a medical treatment, not a shortcut to be self-prescribed.

## What is Semaglutide used for?

- Type-2 diabetes — lowering blood sugar, usually added to metformin or other drugs (Ozempic, Rybelsus)
- Chronic weight management in obesity, alongside diet and exercise (Wegovy; Ozempic is often used off-label for this)
- Reducing the risk of heart attack and stroke in people with type-2 diabetes and established heart disease
- Helping appetite control and portion size through its effect on gut and brain signals
- A once-weekly option (or daily tablet) for people not reaching target on older diabetes medicines

## Dosage

Always follow a doctor's or pharmacist's instructions; this is general reference information.

- Adults: Semaglutide is always started low and increased gradually to reduce nausea. Ozempic (injection) typically starts at 0.25mg once a week for 4 weeks, then 0.5mg weekly, increasing to 1mg or 2mg if needed. Wegovy escalates over months to 2.4mg weekly for weight loss. Rybelsus (tablet) starts at 3mg once daily, rising to 7mg then 14mg; it must be taken on an empty stomach with a small sip of water, at least 30 minutes before any food, drink, or other medicine. Your doctor sets and adjusts the dose — never rush the increases.
- Children: Semaglutide is not routinely used in children in Nigeria; any use in adolescents (for example Wegovy for obesity where licensed) must be specialist-led.
- Elderly: Can be used in older adults, but with careful monitoring for dehydration from nausea/vomiting and for kidney function.

Inject on the same day each week (Ozempic/Wegovy) into the abdomen, thigh, or upper arm, rotating the site. Keep unopened pens in the fridge; do not freeze. If you miss a weekly dose, take it within a few days — otherwise skip it; never double up. Nausea is common at first and usually eases; eating smaller, lower-fat meals helps. This is a long-term treatment, and weight tends to return if it is stopped without a plan, so use it under medical guidance rather than in on-off cycles.

## Side effects

Common: Nausea — very common when starting or increasing the dose, usually improving with time; Vomiting, diarrhoea, or constipation; Reduced appetite and feeling full quickly; Burping, bloating, or indigestion; Tiredness, and occasionally dizziness.

Serious (seek medical help immediately): Severe, persistent abdominal pain (possibly spreading to the back) with vomiting — a possible sign of pancreatitis; stop and seek urgent care; Gallbladder problems: pain in the upper-right abdomen, fever, or yellowing of the skin/eyes; Signs of dehydration or kidney strain from heavy vomiting/diarrhoea; Low blood sugar (more likely if combined with insulin or a sulfonylurea): shakiness, sweating, confusion; A lump or swelling in the neck, hoarseness, or trouble swallowing (rare thyroid concern); Signs of a serious allergic reaction: swelling of the face or throat, difficulty breathing.

When to see a doctor: Seek urgent care for severe or persistent abdominal pain, repeated vomiting with signs of dehydration, or symptoms of a serious allergic reaction. Contact your doctor if nausea is severe enough to stop you eating or drinking, if you have symptoms of low blood sugar, or if you notice neck swelling. Because semaglutide slows stomach emptying, tell any doctor or anaesthetist you are on it before surgery or a procedure that needs sedation.

## Warnings

Do not take if: Do not use in type-1 diabetes or for diabetic ketoacidosis; Do not use if you have had medullary thyroid cancer, or a family history of it, or the syndrome MEN 2; Avoid if you have had pancreatitis, unless a specialist advises otherwise; Do not use in pregnancy or while breastfeeding — stop it well before a planned pregnancy; Do not use if you are allergic to semaglutide.

Interactions: Insulin and sulfonylureas (e.g. glibenclamide): combining raises the risk of low blood sugar — doses may need lowering; Because semaglutide slows stomach emptying, it can affect how other oral medicines are absorbed; spacing may be advised; Oral contraceptive pills: severe vomiting can reduce their reliability — use backup contraception if unwell; Warfarin and other drugs needing monitoring may need closer checks when starting.

Pregnancy & breastfeeding: Semaglutide must not be used in pregnancy or while breastfeeding — there is not enough safety data and it should be stopped at least two months before trying to conceive. This matters especially for weight-loss users: rapid weight loss and improved fertility can lead to unplanned pregnancy, so reliable contraception is important while on it. If you become pregnant, stop the medicine and tell your doctor promptly.

## How to verify it is genuine

1. Buy only from a licensed pharmacy — the enormous demand for Ozempic and Wegovy has made them a top target for counterfeiters
2. Check the NAFDAC registration number on the pack and verify it on the NAFDAC Green Book or mobile app before paying
3. Be extremely suspicious of low prices — genuine semaglutide costs hundreds of thousands of naira; a cheap 'Ozempic' pen is almost certainly fake
4. Insist on proper cold-chain storage: genuine pens are kept refrigerated, and a pen sold warm or from an unrefrigerated stall should be refused
5. Check the pen, label, expiry date, and batch number carefully; reject anything with spelling errors, blurry printing, missing details, or tampered packaging
6. Avoid social-media sellers, 'weight-loss coaches', and unregistered online vendors — this is a prescription medicine that needs a real pharmacy and a doctor

## FAQs

### Is semaglutide (Ozempic) NAFDAC-registered in Nigeria?

In our July 2026 copy of the NAFDAC Greenbook — 11,695 registered medicines — no semaglutide product appears under any name we checked, including Ozempic, Wegovy and Rybelsus. That does not automatically make every pen sold here fake, but it means a semaglutide product offered in Nigeria cannot currently be matched to an entry in the medicines register, so there is no registration number to verify before you buy. Counterfeit Ozempic pens have been reported internationally, so treat any 'NAFDAC-approved Ozempic' claim with suspicion: ask for the number, check it on the official Green Book, and confirm the product name and holder it returns actually match the pack.

### Can I use Ozempic just to lose weight?

Semaglutide does cause significant weight loss, and a higher-dose version (Wegovy) is licensed specifically for weight management — but it is a prescription medicine, not a lifestyle product, and it should be started and monitored by a doctor. It has real side effects (persistent nausea, and rarer risks like pancreatitis and gallbladder problems), needs the dose built up slowly, and weight usually returns if it is stopped without a plan. Self-prescribing it from an online seller — especially given the counterfeit problem in Nigeria — is risky. If weight loss is your goal, see a doctor to decide whether it is appropriate and safe for you.

### What is the difference between Ozempic, Wegovy, and Rybelsus?

All three contain the same active ingredient, semaglutide, made by Novo Nordisk, but they differ in form, dose, and licensed use. Ozempic is a once-weekly injection licensed for type-2 diabetes (and widely used off-label for weight loss). Wegovy is a once-weekly injection at higher doses licensed specifically for weight management. Rybelsus is a daily tablet for type-2 diabetes — convenient because it avoids injections, but it must be taken on an empty stomach with only a sip of water, well before eating. Your doctor chooses based on whether you're treating diabetes or weight, and on cost and availability.

### Is Ozempic safe, and who should not take it?

For the right person under medical supervision, semaglutide is an effective, well-studied medicine — but it is not for everyone. It should not be used in type-1 diabetes, in pregnancy or breastfeeding, or by anyone with a personal or family history of medullary thyroid cancer or the MEN 2 syndrome, and it is used cautiously in people who have had pancreatitis. The most common problem is nausea; rarer but serious risks include pancreatitis and gallbladder disease. It also interacts with insulin and sulfonylureas to cause low blood sugar. A doctor should decide whether it suits your health, and monitor you while you take it.
