## Price in Nigeria

Denosumab prices in Nigeria vary by brand, strength, and where you buy it. Confirm the current price with a licensed pharmacy, and always check the product is NAFDAC-registered before you pay.

## What is Denosumab?

Denosumab is a monoclonal antibody that stops bone being broken down. It binds RANK ligand, the signal that tells osteoclasts — the cells that dissolve old bone — to get to work. Blocking that signal tips the balance toward bone being built rather than removed, and it raises bone density and cuts fracture risk substantially. It is given as an injection under the skin: every six months for osteoporosis, under the brand Prolia, or monthly at a higher dose for bone complications of cancer, as Xgeva.

DENOSUMAB IS NOT REGISTERED WITH NAFDAC. Our copy of the NAFDAC Greenbook holds no record of it under any brand or ingredient name, active or lapsed. There is no legal supply in Nigeria.

It is not alone. Alendronate — the cheap weekly tablet that is first-line osteoporosis treatment across most of the world — is also absent from the register, as are risedronate and raloxifene. What Nigeria does have registered are the injectable bisphosphonate zoledronic acid, given once a year, and teriparatide. So osteoporosis is treatable here, but the treatment ladder starts at the rung most countries reach for last.

## What is Denosumab used for?

- Nothing approved in Nigeria — denosumab holds no NAFDAC registration
- Osteoporosis in postmenopausal women at high fracture risk, where it is licensed abroad
- Osteoporosis in men, and bone loss caused by hormone-blocking cancer treatment, abroad
- Preventing fractures and bone pain where cancer has spread to bone, as Xgeva, abroad
- Giant cell tumour of bone, abroad

## Dosage

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

- Adults: No dose is given here for a medicine with no legal supply in Nigeria. Where licensed, Prolia is 60mg injected under the skin once every six months, always alongside adequate calcium and vitamin D.
- Children: Denosumab is not used in growing children outside very specific specialist circumstances; it interferes with normal bone growth.
- Elderly: Not applicable in Nigeria. Osteoporosis is largely a condition of older people, and denosumab is used in them abroad without routine dose adjustment.

The most important thing to know about denosumab is what happens when it stops. Its effect is not retained: bone loss rebounds rapidly after a missed or delayed dose, and there is a recognised risk of multiple spinal fractures in the months after discontinuation. It must not simply be stopped, and it must not be started somewhere the next dose cannot be guaranteed six months later. For a medicine with no registered supply in Nigeria, that is a serious practical warning — a course begun abroad and interrupted on returning home can leave someone worse off than if it had never been started.

## Side effects

Common: Back, muscle and joint pain; Pain in the arms or legs; Skin rash and eczema; Fatigue; Constipation or diarrhoea.

Serious (seek medical help immediately): Low blood calcium (hypocalcaemia), which can be severe in kidney impairment or vitamin D deficiency; Osteonecrosis of the jaw — rare, but more likely at the higher cancer doses and after dental extraction; Atypical femoral fracture — an unusual thigh-bone break after long use; Serious skin and soft-tissue infections; Rebound vertebral fractures after stopping.

When to see a doctor: Not applicable to a medicine unavailable here. Anyone receiving denosumab abroad should report numbness or tingling around the mouth, muscle cramps or spasms — signs of low calcium — and any jaw pain, loose tooth or non-healing socket after dental work. Dental treatment should ideally be completed before starting.

## Warnings

Do not take if: No lawful supply in Nigeria — denosumab holds no NAFDAC registration; Untreated low blood calcium — this must be corrected before any dose; Pregnancy; Known hypersensitivity to denosumab.

Interactions: Other medicines that lower calcium — additive risk of hypocalcaemia; Immunosuppressants and corticosteroids such as prednisolone — added infection risk; Bisphosphonates such as zoledronic acid — not given together; Calcium and vitamin D are given WITH denosumab rather than avoided; deficiency makes it dangerous.

Pregnancy & breastfeeding: Denosumab is contraindicated in pregnancy — it crosses the placenta and can harm fetal bone development. Effective contraception is required during treatment and for five months after the last dose. It is not recommended while breastfeeding.

## How to verify it is genuine

1. There is nothing to verify. Denosumab holds no NAFDAC registration, so no genuine Nigerian registration number exists for Prolia, Xgeva or any denosumab product.
2. A denosumab pack printed with a NAFDAC number is showing a number that was invented or cloned — check it against our NAFDAC checker.
3. Denosumab is a biological medicine that must be kept refrigerated from factory to injection. A pre-filled syringe offered outside a hospital cold chain should be refused whatever its paperwork says: a broken cold chain ruins it invisibly.
4. If you are receiving denosumab abroad, plan the next dose before travelling. The rebound fracture risk after a delayed dose makes an interrupted course genuinely dangerous.
5. For osteoporosis being treated in Nigeria, zoledronic acid and teriparatide are registered here, and calcium with vitamin D underpins any treatment. Ask a doctor which applies.

## FAQs

### Is Prolia available in Nigeria?

No. Denosumab — sold as Prolia for osteoporosis and Xgeva for cancer-related bone disease — holds no NAFDAC registration, and our copy of the Greenbook contains no record of it under any name. There is no legal supply in Nigeria. Anything offered here under those names arrived outside the registered channel, and for a refrigerated biological medicine that is a particular problem, because a broken cold chain leaves no visible trace.

### What osteoporosis treatment is available in Nigeria?

Less than most people expect. Alendronate, the cheap weekly tablet that is first-line almost everywhere in the world, is not registered here, and neither are risedronate or raloxifene. What is registered is zoledronic acid, an infusion given once a year, and teriparatide. Calcium and vitamin D are widely available and are the foundation of any treatment. The practical result is that Nigerian osteoporosis care starts with options other countries keep in reserve, which is worth knowing before you assume your doctor is over-treating you.

### Why is stopping denosumab dangerous?

Because its effect is not banked. Bisphosphonates linger in bone for years after the last dose; denosumab does not. When it is stopped or a dose is delayed, bone turnover rebounds sharply and there is a recognised risk of multiple spinal fractures within months. This is why it should never be started unless the next dose six months later is assured — and why beginning a course abroad and returning to a country where the medicine is not registered is a genuine risk rather than an inconvenience.

### How much does denosumab cost?

This page does not quote a Nigerian price because there is no legal Nigerian market to quote from. Internationally it is an expensive biological medicine, and any price offered here would reflect an unregistered import rather than a market rate. If cost is the reason you are considering an unofficial source, discuss the registered alternatives with a doctor instead — the annual zoledronic acid infusion is usually far cheaper than six-monthly imported injections.

### Why write about a drug Nigeria does not have?

Because someone told about Prolia by a doctor abroad, or reading about osteoporosis online, has no straightforward way to find out whether it exists on the Nigerian market. That silence gets filled by sellers. Saying plainly that it is unregistered, explaining the rebound risk that makes an interrupted course dangerous, and naming what is registered here is more useful than leaving the question open.
