Sildenafil Price Comparison UK: Viagra and Generic Tablets

Sildenafil and Viagra · Prices checked 15 October 2026

Compare sildenafil and Viagra prices, pack for pack

Sildenafil prices in this UK comparison range from £3.50 to £15 for four generic 50mg tablets before separate fees. Branded Viagra costs more. This guide separates the two, matches strengths and pack sizes, and adds verified charges so you can compare the cost of treatment you have actually been prescribed.

The quick answer: brand and fees change the bill

For four 50mg tablets, generic sildenafil costs £6.99 at The Care Pharmacy, compared with £29.99 for branded Viagra. With our £3.99 standard delivery, those totals become £10.98 and £33.98. That is a £23 difference for the same active ingredient and strength, before considering other providers.

In this sample, Dr Fox has the lowest generic four-tablet medicine prices. Asda Online Doctor has the lowest branded Viagra 50mg and 100mg four-tablet prices. The Care Pharmacy is not the cheapest in every comparison, and the tables show that openly.

We compared publicly advertised prices at four UK services without discount codes, loyalty rewards or introductory offers. This is a dated sample, not the whole market. The Care Pharmacy sells both products and produced this guide; no order was placed with another provider.

Generic sildenafil prices for four tablets

Read across the column for your prescribed strength. All entries are generic film-coated tablets, with four tablets per pack. These are advertised medicine or treatment-pack prices before any separately charged fees, rather than guaranteed checkout totals.

Generic sildenafil: four tablets · 15 October 2026
Provider 25mg × 4 50mg × 4 100mg × 4
The Care Pharmacy £5.99 £6.99 £7.99
Dr Fox £3.20 £3.50 £4.50
Boots Online Doctor £16.00 £15.00 £25.00
Asda Online Doctor £14.00 £14.50 £20.00

A low “from” price may apply to 25mg or to a larger quantity. It does not tell you the cost of your own pack. At The Care Pharmacy, the four-tablet 50mg pack is £6.99; the £5.99 starting price belongs to 25mg. Matching the strength avoids a misleading saving.

Sildenafil prices for eight-tablet packs

Eight-tablet packs have their own prices. Do not assume they cost exactly twice as much as four, or that every larger pack offers a better unit price.

Generic sildenafil: eight tablets · 15 October 2026
Provider 25mg × 8 50mg × 8 100mg × 8
The Care Pharmacy £8.99 £12.99 £14.99
Dr Fox £7.45 £9.80 £9.50
Boots Online Doctor £24.00 £28.00 £35.00
Asda Online Doctor £18.00 £22.00 £30.00

For example, The Care Pharmacy’s 50mg price works out at about £1.75 per tablet in a four-tablet pack and £1.62 in an eight-tablet pack, before delivery. At Dr Fox, four 50mg tablets cost less per tablet than eight in the prices checked. The arithmetic is worth doing each time.

A prescriber still needs to agree the quantity. Buying extra tablets to reduce delivery charges is not a reason to take treatment more often. Sildenafil is used when needed for erection difficulties; a pack is not automatically a month’s supply.

Branded Viagra prices, kept separate

If you want branded Viagra, compare it against branded Viagra. Generic sildenafil contains the same active ingredient, but mixing the cheapest generic with the dearest brand would not be a fair provider ranking. These figures cover prescription Viagra tablets, not Viagra Connect, films or sprays.

Branded Viagra: matching strengths and quantities · 15 October 2026
Provider 50mg × 4 50mg × 8 100mg × 4 100mg × 8
The Care Pharmacy £29.99 £54.99 £34.99 £59.99
Dr Fox £29.40 £59.50 £33.80 £64.45
Asda Online Doctor £29.00 £49.00 £30.60 £55.00

The branded four-tablet prices are close enough that fees can change the order. Dr Fox’s 50mg medicine price is 59p below ours, but its prescription fee and delivery bring the total above ours. Asda’s advertised free delivery leaves it lower than both for this particular pack.

For current strengths and quantities, see our branded Viagra information and generic sildenafil information. Tell the clinician which you have used before and whether you have a brand preference. The assessment determines what can be supplied.

What one 50mg pack costs with standard delivery

These examples are for one four-tablet pack, one order and standard delivery. Dr Fox charges a prescription fee of £1 for an order value up to £10 and £3 for an order value over £20 up to £40, plus £2.90 delivery. Its generic and branded examples therefore attract different fees.

Four 50mg tablets: advertised pack plus standard fees · 15 October 2026
Product and provider Pack price Separate charges Total
Generic · The Care Pharmacy £6.99 £3.99 delivery £10.98
Generic · Dr Fox £3.50 £1.00 prescription + £2.90 delivery £7.40
Generic · Asda Online Doctor £14.50 Free delivery advertised £14.50
Viagra · The Care Pharmacy £29.99 £3.99 delivery £33.98
Viagra · Dr Fox £29.40 £3.00 prescription + £2.90 delivery £35.30
Viagra · Asda Online Doctor £29.00 Free delivery advertised £29.00

Our delivery policy lists standard delivery at £3.99, free on orders over £40. Premium services cost more. For an eligible eight-tablet branded pack priced at £54.99, that threshold changes the delivery calculation. It does not apply to the £12.99 generic pack.

Check the final total before paying. These calculations use published pack prices and separate fees we could verify; they are not completed invoices. A delivery estimate also starts from the provider’s processing or dispatch arrangements, not necessarily the moment you begin an assessment.

Make a fair comparison before switching

Keep these details beside any quote:

  • The medicine’s name, brand where relevant, strength and tablet count.
  • Any prescription, consultation and delivery charges.
  • Whether the price is a one-off offer or applies to repeat orders.
  • How you can contact the service if treatment does not help or causes problems.

A cheaper pack is useful only if it matches the treatment agreed for you. Do not choose 100mg because its unit price looks attractive, split tablets to create an unapproved plan, or combine Viagra with another sildenafil product. Discuss any change with your prescriber.

If another medicine is being considered, our Cialis and tadalafil price guide covers its costs separately. Different medicines and dosing schedules need their own assessment; price alone cannot decide between them.

Suitability comes before the price

Do not take sildenafil with nitrates for chest pain, “poppers” or riociguat. Tell the clinician about heart problems, low blood pressure, recent stroke or heart attack, and every medicine you use. The Viagra patient leaflet gives the full warnings and interactions; read the leaflet supplied with your own pack.

Headache, flushing, indigestion and dizziness can occur. Seek emergency help for chest pain, severe breathing difficulty or sudden loss of vision. Do not use nitrates for chest pain after sildenafil; tell emergency staff what you took and when. Get urgent help for a prolonged or painful erection.

Repeated erection difficulties deserve a GP or sexual-health assessment because diabetes, cardiovascular problems, medicines and psychological factors can contribute. The NHS guide to erection problems explains the wider checks and treatment options. A repeat order should not replace that conversation.

Sildenafil prices: common questions

Is generic sildenafil cheaper than Viagra?

Yes in the matched packs in this sample. At The Care Pharmacy, four 50mg generic tablets cost £6.99 and branded Viagra costs £29.99 before delivery. Both contain sildenafil; the brand name does not mean a higher strength.

Does the lowest pack price mean the lowest total?

No. Prescription fees and delivery can change the comparison. For four branded 50mg tablets, Dr Fox lists a lower pack price than The Care Pharmacy, but the standard delivered total is higher in the example above.

Are Viagra Connect prices included?

No. Viagra Connect has a different pharmacy-supply route and should be labelled separately. This guide compares generic sildenafil tablets and prescription branded Viagra, keeping strengths and quantities matched.

How often should I check sildenafil prices?

Check when you are ready to request treatment or a repeat supply. Prices, delivery thresholds and offers can change. Use the same strength and quantity, then confirm the full total before payment.

Discuss erection difficulties with a clinician

The Care Pharmacy’s erectile dysfunction service assesses symptoms, medical history and current medicines before recommending treatment. You can ask about suitable options and their full cost before deciding. Completing an assessment does not guarantee a prescription or supply.
