Sildenafil Price Comparison – Nov 2025, UK

Cheapest Sildenafil – 25mg

As we do with all our monthly comparisons, we’ve only included pharmacies that appear in the top five cheapest for at least one pack size. We’ve also left out non standard pack sizes too, but you can still find those in the full list.

• Note: Prices correct as of 23 Nov 2025.
• Dr Fox leads on 25mg starter packs, posting the lowest 4 tablet price at £4.20 (£1.05 per pill). It narrowly beats Simple Online Pharmacy (£4.25) and Chemist4U (£4.39), making it the best for people new to Sildenafil.
• Cloud Pharmacy is the bulk winner this month. Their 64 tablet pack comes in at £30.08 (47p per pill), the best per pill price for 25mg, and the cheapest sildenafil if you’re stocking up.
• Simple Online Pharmacy has the mid pack sweet spot, because their 16 tablet pack is only £13.89 (87p per pill). That’s cheaper per pill than most 8–12 packs elsewhere, so it’s a great step up size if you don’t want to commit to 32 or 64 yet.

50mg

50mg is the usual starting dose for most men using Sildenafil on a private prescription, so this is where competition is tightest and prices are most meaningful to compare. If you’re looking for the cheapest sildenafil option, 50mg is typically the one to benchmark first.

• Farmeci is fractionally cheapest on 50mg standard 4 packs, with 4 tablets for £5.94 (£1.49 per pill). Dr Fox is essentially level at £5.95, but Farmeci wins the headline by 1p at the smallest size.
• Dr Fox dominates on bulk buying, with the lowest 64 tablet total at £47.50 (74p per pill). The downside is they are missing mid packs (no 12 or 24), so the value leap is starter to bulk rather than a smooth scale up.
• Chemist4U is the mid size winner, offering 24 tablets for £22.99 (96p per pill). That’s a massive dip versus most 16 packs and even undercuts several 32 pack unit rates. Basically the best ‘not quite bulk’ deal for 50mg sildenafil.
• Ashcroft Pharmacy stays consistently competitive across sizes, but doesn’t top any of the key mid points this month (12s, 16s, or 24s). It’s a safe pick if availability matters, even though it’s not the absolute cheapest sildenafil.

100mg

100mg is generally taken when 50mg hasn’t been effective enough, so prices here matter most for experienced users stepping up in strength. Because it’s the top standard dose, this is also where bulk packs can make the biggest difference when looking to find the cheapest sildenafil per tablet.

• Farmeci leads on standard 100mg 4 packs, posting 4 tablets for £6.79 (£1.70 per pill). It edges Dr Fox (£6.80) and is clearly ahead of Ashcroft (£7.99),making it the clearest starter price for anyone looking for full strength sildenafil.
• Dr Fox takes the bulk crown again, with 64 tablets for £69.00 (£1.08 per pill), the best big pack rate shown for 100mg and the strongest long term route to cheap sildenafil per tablet.
• Farmeci also owns the mid packs, with 16 tablets for £22.89 (£1.43 per pill). That’s notably better unit value than most competitors’ 8–12 packs, so Farmeci is basically the best ‘starter to mid’ provider at 100mg.
• Ashcroft and Pharmacy Online track each other closely at mid sizes, sitting around £25–26 for 16 and £39–40 for 24, so they’re solid alternates if Farmeci isn’t available.

Sildenafil Discount Codes

A handful of pharmacies are running new customer offers this month, which you can see in our full list. In a few cases the discounts beat the cheapest sildenafil prices, but only for first orders and only at specific pack sizes.

• Oxford Online Pharmacy – Intro pricing undercuts the leaders at several standard sizes – 25mg 8 pack £5.30 (beats Simple Online Pharmacy £7.49), 25mg 12 pack £8.54 (beats Ashcroft £13.95), 50mg 32 pack £37.33 (beats Dr Fox £39.80), and 100mg 64 pack £62.98 (beats Dr Fox £69.00).
• The Independent Pharmacy – Discounted mid packs sneak ahead in a couple of spots – 50mg 12 pack £16.55 (beats Ashcroft £18.99) and 100mg 16 pack £22.07 (beats Farmeci £22.89).
