Best Metformin Alternatives in the UK NHS: Prescribing, Coverage & Co-Pays Explained
Unpacks metformin alternatives in the NHS—explores what gets prescribed, what patients pay, and which medications are covered. Everything explained simply.
If you live in the UK and need diabetes medication, the NHS covers most standard treatments. This guide explains how prescriptions work, what to expect for common drugs (insulin, metformin, GLP‑1s, SGLT2s), and quick steps to avoid running out. No jargon — just what you need to do.
Your GP or diabetes clinic prescribes diabetes meds. Some treatments need clinic monitoring (for example, starting insulin or a GLP‑1 often includes training and follow‑ups). Prescriptions can be issued as paper or electronic (EPS). With EPS your pharmacist can collect the medicine without a paper slip — handy if you use online ordering.
Repeat prescriptions are common for stable diabetes. Ask your GP to set up a repeat if you’re well controlled. Many GP practices offer online repeat services or apps where you can request meds, check doses, and see when your next review is due. If you need urgent supplies, contact your GP surgery or local pharmacy; most places can help while a prescription is issued.
1) Keep an eye on supplies: reorder at least a week before you run out. Don’t wait for the last tablet or insulin pen. Running out creates stress and can affect your blood sugar.
2) Use the NHS repeat prescription service or your surgery’s app — they speed things up. If your GP uses EPS, nominate a local pharmacy and your meds will go straight there.
3) Ask about medication delivery. Many pharmacies offer a free or low‑cost delivery service for repeat prescriptions. This helps if travel or mobility is an issue.
4) Know what needs monitoring. Some drugs need blood tests (kidney function for metformin and SGLT2s; HbA1c checks for overall control). Missed monitoring can delay repeats, so book blood tests early.
5) If you use insulin, get a clear plan for dose changes, sick day rules, and when to call for help. Request diabetes nurse support if you’re unsure; clinics can often fit in a quick phone or face‑to‑face review.
6) Moving or changing GP? Transfer your care smoothly by telling both surgeries and asking for your current prescription history. That keeps repeats active and avoids interruptions.
7) Watch for side effects and interactions. If a new tablet or injection makes you feel off, tell your GP before stopping. They can suggest alternatives or adjust doses safely.
Finally, keep a simple checklist: what drug and dose, when it expires, next blood tests, and your pharmacy details. That small list prevents most supply problems and keeps your diabetes on track.
