Lasix price UK – what you need to know today

If you’ve been prescribed Lasix (furosemide) and wonder how much it will set you back, you’re in the right place. In the UK, the cost can swing widely depending on whether you get it through the NHS, a private pharmacy, or an online vendor. Below we break down the typical price ranges, what factors drive those numbers, and simple ways to keep the bill low.

How much does Lasix cost in the UK?

For most patients the NHS covers Lasix when it’s listed on the British National Formulary. If you have a valid prescription, you usually pay the standard NHS prescription charge – £9.35 per item (as of 2025). Some patients qualify for free prescriptions, for example those over 60, under 16, or on certain medical benefits.

If you go the private route, the price jumps. A 20 mg tablet of brand‑name Lasix typically retails between £3 and £5 per tablet, while the generic furosemide version can be as low as £0.50‑£1 per tablet. A typical 30‑day supply of 40 mg tablets might therefore cost anywhere from £15 to £30 in a high‑street pharmacy.

Tips to save on Lasix

First, ask your doctor if the generic version is suitable – it’s chemically identical and usually much cheaper. Second, check if your local pharmacy offers a discount card or bulk‑buy programme; many chains give a 10‑15% cut when you buy a two‑week or a month’s supply at once.

Online pharmacies can also be a good option, but only use regulated UK sites that display a valid pharmacy registration number. Compare at least three reputable sites, factor in delivery fees, and look for promo codes that shave a few pounds off the total.

Finally, don’t forget about NHS repeat prescriptions. Setting up an automatic repeat can save you the hassle of multiple trips and sometimes unlock additional discounts through your GP practice’s pharmacy partner.

Bottom line: if you’re covered by the NHS, the out‑of‑pocket cost is just the prescription charge. If you’re paying privately, aim for generic furosemide, bulk ordering, and verified online pharmacies to keep the expense in check.
