At a glance
- Typical private cost: £2–£7 per on-demand tablet, or roughly £15–£45 per month for the 2.5mg/5mg daily dose
- Generic version of Cialis, available in the UK since the patent expired in 2017 — same active ingredient at a lower price
- Prescription-only: an online consultation reviewed by a prescriber is always required, and the pharmacy can decline supply
- Two dosing approaches: on-demand tablets (10mg/20mg) effective for up to around 36 hours, or a low daily dose (2.5mg/5mg)
- The longer action window is why it is sometimes described as "the weekend pill" — a descriptive label, not a clinical claim
- ED medicines are heavily counterfeited — only buy from GPhC-registered pharmacies; check the register at pharmacyregulation.org

What the price covers
UK online pharmacies price tadalafil as a treatment service: the published price normally includes the online consultation, review by a prescriber, the tablets, and tracked delivery. There are two pricing patterns to compare. On-demand tablets (10mg or 20mg) are priced per pack, typically working out at £2–£7 per tablet, with larger packs costing less per tablet. The low daily dose (2.5mg or 5mg) is priced as a monthly supply, typically £15–£45 per month depending on the pharmacy and pack size. Because the two dosing approaches are priced differently, compare pharmacies on the regimen you'd actually be prescribed, and confirm whether consultation and delivery are included in the headline price.
Who can be prescribed it and how the consultation works
Tadalafil is a prescription-only medicine in the UK, licensed for the treatment of erectile dysfunction in adult men. Every legitimate online pharmacy runs a structured consultation — a health questionnaire covering blood pressure, heart conditions, current medicines (particularly nitrates, which cannot be combined with tadalafil), and relevant history — which a prescriber reviews before approving, asking follow-up questions, or declining. Suitability is not guaranteed. The prescriber also decides between on-demand and daily dosing: on-demand suits occasional use, while the low daily dose maintains a steady level of the medicine, which some men prefer for spontaneity. That choice, and the dose itself, is a clinical decision — not something to select on price alone.
How tadalafil compares with sildenafil
Tadalafil and sildenafil are both prescription-only ED treatments, but they differ in duration: sildenafil's effects last up to around 4 hours, while a single on-demand tadalafil tablet can remain effective for up to around 36 hours — the origin of the informal "weekend pill" label. Tadalafil is also the only one of the two commonly prescribed as a continuous low daily dose. Per-tablet prices for the two generics are broadly similar, so cost is rarely the deciding factor; which medicine suits your health, other medicines, and pattern of use is for the prescriber to assess during the consultation. Neither is available without a prescription — unlike sildenafil, tadalafil has no pharmacist-supplied equivalent of Viagra Connect.
Safety, counterfeits, and side effects
Erectile dysfunction medicines are among the most counterfeited drugs in the world, so buying only from GPhC-registered pharmacies matters more here than in almost any other category — counterfeit tablets sold through unregistered websites and social media may contain the wrong dose, no active ingredient, or harmful substances. Check any unfamiliar pharmacy on the GPhC register at pharmacyregulation.org before ordering. Common side effects include headache, back pain, muscle aches, flushing, and indigestion; tadalafil must not be taken with nitrate medicines, which the consultation screens for. Report suspected side effects through the MHRA Yellow Card scheme, and contact the pharmacy's clinical team or your GP if you're unwell. This page compares prices only — it is not medical advice.
Frequently Asked Questions
Can I buy tadalafil without a prescription?▼
No. Tadalafil is a prescription-only medicine in the UK — every legitimate pharmacy requires a consultation reviewed by a prescriber before supply, and can decline if treatment isn't suitable. Unlike sildenafil, there is no pharmacist-supplied version equivalent to Viagra Connect. Any website offering tadalafil with no consultation is unregistered or illegitimate — check the GPhC register at pharmacyregulation.org.
What's the difference between on-demand and daily tadalafil?▼
On-demand tadalafil (10mg or 20mg) is taken before it's needed and can remain effective for up to around 36 hours. Daily tadalafil (2.5mg or 5mg) is a lower dose taken every day, maintaining a steady level of the medicine. On-demand is priced per tablet; daily is priced per month. Which regimen is appropriate is a decision for the prescriber during the consultation.
Is generic tadalafil the same as Cialis?▼
Generic tadalafil contains the same active ingredient at the same doses as Cialis and is made to the same UK regulatory standards. Generics have been available since the Cialis patent expired in 2017, which is why per-tablet prices fell substantially. Branded Cialis is still sold at a higher price.
Why do tadalafil prices differ between pharmacies?▼
Each pharmacy sets its own service price covering consultation, prescribing, the tablets, and delivery, and their overheads differ. Pack size and regimen matter too — larger on-demand packs cost less per tablet, and monthly daily-dose pricing varies by pharmacy — so compare on the regimen and quantity you'd actually be prescribed.
Should I take tadalafil or sildenafil?▼
That is a clinical decision, not a price one. The main practical difference is duration — tadalafil lasts up to around 36 hours versus around 4 for sildenafil, and tadalafil is also available as a daily dose — but which is suitable depends on your health, other medicines, and pattern of use, all of which the prescriber assesses during the consultation.
