Cialis Price in the UK: How Much Does Tadalafil Cost?

Generic tadalafil starts from under £2 per tablet in the UK, while branded Cialis can cost considerably more. The price you pay depends on whether you choose brand or generic, which dose suits you, and where you buy it. This guide covers real UK prices, the difference between prescription and over-the-counter options, and how to make sure you're getting a safe, legitimate product.

Brand Cialis vs Generic Tadalafil#

Cialis is the brand name. Tadalafil is the active ingredient inside it, and since Eli Lilly's patent expired in the UK in November 2017, other manufacturers have been legally allowed to produce and sell their own versions. These generic versions are medically identical to the original in terms of active ingredient, dose, and effect.

The practical difference is price. Brand-name Cialis carries a significant premium, mostly because of the marketing and research costs that went into developing it originally. Generic tadalafil is just as effective and is what most UK online pharmacies and NHS prescribers now use.

If your GP prescribes tadalafil on the NHS, the prescription charge is £9.90 per item (as of 2025) in England. In Scotland, Wales, and Northern Ireland, prescriptions are free, which changes the cost calculation considerably for men who qualify for NHS treatment.

How Much Does Tadalafil Cost in the UK?#

Here is a straightforward breakdown of what you can expect to pay for tadalafil in the UK, using Totiva's current pricing as a reference point:

As-needed tadalafil (the Cialis equivalent):

• Tadalafil 10mg, 4 tablets: £7.49
• Tadalafil 10mg, 8 tablets: £12.99
• Tadalafil 20mg, 4 tablets: £8.49
• Tadalafil 20mg, 8 tablets: £14.99

Daily tadalafil (low-dose, taken every day):

• Tadalafil 2.5mg, 28 tablets: £9.99
• Tadalafil 5mg, 28 tablets: £14.99

Cialis Together (OTC branded tadalafil 10mg):

• 4 tablets: £14.99
• 8 tablets: £24.99

As-needed tadalafil at 10mg works out to around £1.87 per tablet if you buy eight at a time. Daily tadalafil at 5mg comes to around £0.54 per day on a 28-day supply. These are meaningful differences if you're weighing up long-term costs.

You can explore all of these options on Totiva's ED treatment page.

Prescription Tadalafil vs Cialis Together: What's the Difference?#

This is a question worth spelling out clearly, because the UK landscape changed in 2022 when Cialis Together became available over the counter without a prescription.

Prescription tadalafil is obtained through an online consultation or a GP visit. It is available in doses ranging from 2.5mg (daily) up to 20mg (as-needed). It requires a clinician to assess your suitability, check for drug interactions, and issue a prescription. This route gives you access to the full dose range and tends to be more cost-effective per tablet.

Cialis Together is branded tadalafil 10mg that you can buy over the counter, including through pharmacies like Boots or online pharmacies that run a questionnaire. There is no formal prescription required, but you will still be asked health questions before purchase. It is suitable for men who prefer a straightforward purchase without a clinical consultation, though the price per tablet is higher than generic prescription tadalafil at the same dose.

For men using tadalafil regularly, going through a proper consultation and obtaining generic prescription tadalafil is usually the more cost-effective route. Cialis Together makes sense if you want a one-off purchase without a consultation, or if you have not yet spoken to a clinician about ED.

As-Needed vs Daily Tadalafil#

One of the more useful decisions to make early on is which format suits your lifestyle.

As-needed tadalafil (10mg or 20mg) is taken when you plan to be sexually active. It works within 30 to 60 minutes and the effects can last up to 36 hours. This is why Cialis earned the nickname "the weekend pill." You do not need to time it precisely to a specific moment, which many men find less pressured than sildenafil (which has a shorter window of around 4 to 6 hours).

Daily tadalafil (2.5mg or 5mg) is taken every day at roughly the same time, regardless of sexual activity. After a few days, it builds to a consistent level in your system, meaning you are effectively always ready without planning around a pill. This suits men who are sexually active two or more times per week, or those who find the "planning" aspect of as-needed medication off-putting.

From a cost perspective, daily tadalafil at 5mg works out to about 54p per day. That is comparable to as-needed use for men who use it multiple times a week, and potentially cheaper per encounter if you are very regularly active.

Can You Get Tadalafil on the NHS?#

Yes, in certain circumstances. NHS prescribing of PDE5 inhibitors (the drug class that includes tadalafil, sildenafil, and others) was originally restricted to men with specific underlying conditions. NICE guidance has since broadened access, and many GPs can now prescribe one tablet per week of a PDE5 inhibitor to any man with erectile dysfunction on the NHS.

Conditions that have historically given priority NHS access to tadalafil include diabetes, multiple sclerosis, renal failure, prostate cancer treatment, severe pelvic injury, and spinal cord injury, among others. But it is worth having a direct conversation with your GP regardless of your situation, as prescribing practice has become more flexible.

If you are in Scotland, Wales, or Northern Ireland, you pay no prescription charge at all, which makes NHS tadalafil genuinely free. For men in England, the standard prescription charge applies unless you hold an exemption certificate (such as for a listed medical condition or low income).

Why Prices Vary Between Suppliers#

You will notice that tadalafil prices differ quite a bit between UK online clinics. Several factors drive this:

• Prescription fees: Some services charge a separate consultation or prescription fee on top of the medication cost. Others, including Totiva, build this into the overall price (the consultation itself is free, and you pay only after your treatment is approved).
• Pack sizes: Buying more tablets at once almost always reduces the per-tablet cost.
• Brand vs generic: As covered above, branded products carry a premium.
• Delivery costs: These vary. Some suppliers include free delivery; others charge separately.

When comparing prices, check whether the headline price includes delivery and any consultation fee. A lower per-tablet price with a £5 delivery charge and a £10 prescription fee may not be the best deal.

At Totiva, the online consultation is free and there is no subscription required. You pay for your medication after a UK-registered pharmacist approves it, with delivery included in the pricing.

Is It Safe to Buy Tadalafil Online in the UK?#

This question matters. Counterfeit ED medication is a genuine problem globally, and rogue online suppliers exist. The safest way to buy tadalafil online in the UK is to use a pharmacy registered with the General Pharmaceutical Council (GPhC).

You can verify any UK online pharmacy by checking the GPhC register at pharmacyregulation.org. Legitimate sites will display their GPhC registration number and the MHRA-registered internet pharmacy logo. Totiva is GPhC-registered (registration number 9010997), operated by ZapMeds Limited.

Avoid any site that:

• Sells prescription tadalafil without any health questions or consultation
• Offers prices that seem implausibly low
• Has no verifiable UK pharmacy registration
• Ships from outside the UK with no UK regulatory oversight

Illegal suppliers often provide counterfeit tablets with wrong dosages, contaminants, or no active ingredient at all. The risks go well beyond wasting money.

Tadalafil and Drug Interactions Worth Knowing#

Tadalafil is generally well tolerated, but there are important interactions to be aware of. These are part of the reason a clinical consultation before starting treatment matters.

The most significant interaction is with nitrates, which are used to treat angina (such as glyceryl trinitrate or isosorbide mononitrate). Combining tadalafil with nitrates can cause a dangerous drop in blood pressure and the combination is contraindicated.

Alpha-blockers, commonly prescribed for high blood pressure or benign prostatic hyperplasia, can also lower blood pressure when combined with tadalafil. This does not mean the two cannot be used together, but dosing needs to be managed carefully.

Tadalafil is also licensed in the UK for benign prostatic hyperplasia (BPH) at 5mg daily, separate from its ED indication. Men with both conditions sometimes find daily tadalafil addresses both issues simultaneously, which is worth discussing with a clinician.

If you take any regular medication, a proper consultation (rather than just buying OTC without disclosure) is the safer route. A pharmacist-led consultation, like the one Totiva offers, will screen for interactions as part of the assessment.

Tadalafil vs Sildenafil: A Brief Cost Comparison#

Sildenafil (the generic equivalent of Viagra) is often even cheaper than tadalafil, which makes it worth understanding both options.

At Totiva, sildenafil pricing is:

• Sildenafil 50mg, 4 tablets: £4.99
• Sildenafil 50mg, 8 tablets: £9.99
• Sildenafil 100mg, 4 tablets: £6.99
• Sildenafil 100mg, 8 tablets: £11.99

Sildenafil works in roughly 30 to 60 minutes and lasts 4 to 6 hours. It is effective for most men and tends to be slightly cheaper per tablet than tadalafil. The choice between the two often comes down to how much flexibility you want. Tadalafil's longer duration suits men who prefer not to time anything; sildenafil suits men who are happy with a shorter window and want the lowest possible cost.

ViagraConnect (branded sildenafil 50mg, available over the counter) costs £11.99 for four tablets or £19.99 for eight at Totiva. Like Cialis Together, it carries a brand premium over the generic version.

Getting Started#

If you have been putting off addressing ED because you were not sure about the process or the cost, the numbers above show that effective treatment does not have to be expensive. Generic tadalafil from a legitimate UK pharmacy is accessible, straightforward to obtain, and for many men, makes a real difference.

The right first step is a consultation, not a purchase. Understanding whether tadalafil or sildenafil suits you better, which dose is appropriate, and whether there are any interactions with your existing medication is what a clinical assessment is for.

Totiva's pharmacist-led consultations are free and done entirely online. If you are approved, your medication is dispensed by a GPhC-registered pharmacy and delivered discreetly. There is no subscription, no awkward photos, and no commitment before you know what you are getting. If you would like to get started, you can begin a free consultation here.
