Why your blood sugar stays high despite using your medications every day
Is your Metformin substandard? If your blood sugar won't go down despite taking it daily, the medication quality might be the problem. Stop the guessing game and source verified Metformin monthly.
Substandard Metformin is common in Nigerian open markets, and finding a pharmacy you trust shouldn't feel like a part-time job. Every time you have to switch brands because your usual pharmacy is out of stock, you risk dealing with unverified distributors.
Here's how to tell if your current Metformin is genuine, and how to automate your monthly supply so you never have to hunt for it again.
How to tell if your Metformin is actually working (and not just chalk)
Your blood sugar doesn't respond: If you're taking Metformin consistently and your fasting glucose or HbA1c isn't improving after 3 months, the medication quality should be investigated.
Unusual side effects, or no side effects: Legitimate Metformin commonly causes stomach discomfort, especially when starting. If you're on 1000mg and experiencing zero GI effects, the tablet may contain less Metformin than stated.
Price anomalies: Authentic Metformin 500mg (60 tablets) costs ₦2,000–5,000. If it's ₦800, the economics don't support genuine pharmaceutical manufacturing.
Don't just ask for "Metformin": The 3 formulations you need to know
| Formulation | Brand examples | 60 tablets (₦) | Notes |
|---|---|---|---|
| Metformin IR 500mg | Glucodixer, Glucophage | ₦2,000–5,000 | Immediate release; twice daily |
| Metformin IR 850mg | Glucophage, generic | ₦3,000–6,000 | Higher dose |
| Metformin IR 1000mg | Glucophage, generic | ₦3,500–7,000 | Maximum standard dose |
| Metformin XR 500mg | Glucophage XR | ₦4,000–8,000 | Extended release; fewer stomach issues |
| Metformin XR 750mg | Glucophage XR | ₦5,000–9,000 | Once daily option |
Important: Metformin is a prescription medication. Famasi will not process delivery without a valid prescription.
Why guaranteed sourcing is the only way to beat the open market
Pharmacies in our network are licensed, NAFDAC-registered operations with verified supply chains. When you order Metformin through Famasi:
- The product comes from a registered pharmaceutical supply chain, not an unregulated wholesaler
- NAFDAC registration numbers are verifiable on every product
- You can see the exact manufacturer and batch information
This doesn't mean every single tablet is laboratory-tested. But it eliminates the highest-risk sourcing channels: open markets, unlicensed chemist shops, and pharmacies buying from unverified distributors.
We hear from customers every week who switched to Famasi-sourced Metformin and saw their numbers improve. It's not magic—it's getting the real medication at the dose your doctor prescribed.

What Our Customers Say
I've been diabetic for 8 years. The difference between market Metformin and Famasi-sourced Glucophage is real. My fasting sugar dropped from 180 to 140 after switching. Coincidence? I don't think so.
— Adebayo S., Lagos
My Doctor prescribed Glucophage XR. Most pharmacies don't have it. Famasi delivered it to my house in Port Harcourt within 2 days. The packaging was sealed and came with a NAFDAC slip.
