What is Cialis?
Cialis is the brand name for the active pharmaceutical ingredient tadalafil. Developed by the manufacturer Eli Lilly and Company, Cialis is a prescription medicine widely prescribed for the treatment of erectile dysfunction (ED) and the signs and symptoms of benign prostatic hyperplasia (BPH). It belongs to a class of drugs known as phosphodiesterase type 5 inhibitors (PDE5 inhibitors). These medicines work by increasing blood flow to the penis during sexual stimulation, helping adults achieve and maintain an erection sufficient for sexual activity. Cialis distinguished itself at launch by offering a longer half-life than similar agents, allowing for both on-demand use and daily dosing regimens.
Since its introduction, Cialis has become a leading ED therapy across Europe and North America. Its oral tablets are designed for easy swallowing and rapid absorption. Beyond its use in erectile dysfunction, health professionals sometimes use tadalafil off-label to improve exercise capacity in patients with pulmonary arterial hypertension under specialist supervision. In the UK, specific tadalafil products are available as prescription-only medicines (POM) or, subject to reclassification changes, as Pharmacy (P) medicines in low-dose daily formulations. Always consult with a qualified pharmacist or doctor before starting any new medicine.
Therapeutic indications of tadalafil
Erectile dysfunction (ED)
The primary indication for Cialis is the treatment of erectile dysfunction in adult men. Erectile dysfunction is defined by the persistent inability to achieve or maintain an erection sufficient for satisfactory sexual performance. Clinical trials have demonstrated that a single dose of tadalafil, taken prior to anticipated sexual activity, can significantly improve erectile function compared to placebo. Cialis may be taken as needed, at doses ranging from 5 mg to 20 mg, approximately 30 minutes before sexual intercourse.
Benign prostatic hyperplasia (BPH)
Tadalafil at a daily dose of 5 mg is authorised in the UK for the treatment of the signs and symptoms of benign prostatic hyperplasia. BPH is a non-cancerous enlargement of the prostate gland that can cause urinary difficulties, such as increased frequency, urgency and hesitancy. Daily tadalafil helps relax smooth muscle in the bladder and prostate, improving urinary flow rates and decreasing lower urinary tract symptoms associated with BPH.
Combination of ED and BPH
Some patients present with both erectile dysfunction and benign prostatic hyperplasia concurrently. In these cases, tadalafil daily dosing at 5 mg has been shown to address symptoms of both conditions simultaneously, offering a dual therapeutic benefit.
Pulmonary arterial hypertension (PAH) – off-label
Under specialist direction, tadalafil has also been used off-label to treat pulmonary arterial hypertension, a rare but serious vascular disorder affecting the lungs’ blood vessels. Although this indication is outside the standard marketing authorisation for Cialis tablets in the UK, specialist cardiologists may prescribe tadalafil as part of combination therapy in severe cases.
How Cialis works: mechanism of action
Phosphodiesterase type 5 (PDE5) inhibition
Cialis exerts its therapeutic effect by selectively inhibiting the enzyme phosphodiesterase type 5 (PDE5). PDE5 is found predominantly in the smooth muscle cells lining the blood vessels of the corpus cavernosum in the penis as well as the smooth muscle of the prostate and bladder. By inhibiting PDE5, tadalafil prevents the degradation of cyclic guanosine monophosphate (cGMP), a secondary messenger responsible for smooth muscle relaxation.
Role of nitric oxide (NO)
Sexual stimulation triggers the release of nitric oxide (NO) in the corpus cavernosum. NO activates guanylate cyclase, increasing levels of cGMP within smooth muscle cells. Elevated cGMP causes relaxation of smooth muscle, leading to increased blood flow into the erectile tissues and helping produce an erection. Cialis amplifies this physiological pathway by maintaining higher cGMP concentrations for longer periods.
On-demand vs daily dosing
The unique pharmacological profile of tadalafil, with a half-life of approximately 17.5 hours, allows a window of action up to 36 hours with a single on-demand dose. This contrasts with other PDE5 inhibitors, which typically last 4 to 6 hours. Cialis also offers a daily low-dose regimen (5 mg once daily) for patients preferring spontaneity without planning, and for those with concomitant BPH symptoms.
Tissue selectivity
Though PDE5 is widely distributed in various tissues, tadalafil demonstrates high selectivity for the PDE5 isoform, reducing the risk of off-target effects in other PDE pathways. This selectivity contributes to the efficacy and tolerability profile seen in clinical use.
Pharmacokinetics and onset of action
Absorption and bioavailability
Cialis is rapidly absorbed after oral administration, with peak plasma concentrations (Cmax) achieved between 2 and 4 hours post-dose. The presence of food in the stomach does not significantly affect tadalafil’s bioavailability, allowing flexibility in dosing with or without meals.
Distribution and protein binding
Tadalafil is highly protein bound (≈94%), primarily to albumin. The volume of distribution (Vd) is approximately 0.8 L/kg, indicating moderate tissue penetration. Its distribution into genital tissues supports the prolonged pharmacodynamic effect observed in clinical studies.
Metabolism
Tadalafil is extensively metabolised by the hepatic cytochrome P450 enzyme CYP3A4 to inactive metabolites, which are primarily excreted in the feces (≈61%) and urine (≈36%). Patients with severe hepatic impairment require careful dose adjustment or may be advised to use an alternative PDE5 inhibitor.
Elimination half-life
The elimination half-life of tadalafil is approximately 17.5 hours, significantly longer than most other PDE5 inhibitors. This extended half-life underpins the “weekend pill” moniker sometimes applied to Cialis due to its prolonged window of efficacy.
Steady-state kinetics
With daily dosing at 5 mg, tadalafil reaches steady-state concentrations within 5 days. Dose adjustments in renal impairment or when co-administered with certain CYP3A4 inhibitors may be required in line with product labelling.
Dosage, administration and packaging
On-demand dosing
For most patients, the recommended starting dose of Cialis for on-demand use is 10 mg, taken prior to anticipated sexual activity. Based on efficacy and tolerability, the dose may be increased to 20 mg or decreased to 5 mg. The maximum recommended dosing frequency is once per day.
Daily dosing
A daily regimen of 5 mg tadalafil is available for patients who anticipate frequent sexual activity (e.g., at least twice weekly) and for those who prefer the convenience of spontaneity. Daily dosing may also benefit patients with BPH. Tablets for daily use are usually provided in smaller-dose packaging and can be prescribed as a Pharmacy medicine where authorised.
Packaging and blister cards
Cialis tablets are provided in sealed blister cards to maintain stability and protect against moisture. Typical pack sizes include 4-count blisters for on-demand tablets (5 mg, 10 mg, 20 mg) and 14- to 28-count blisters for daily tablets (2.5 mg, 5 mg). Pharmacies in the UK supply medications in original packaging to ensure authenticity and maintain the medicine’s shelf life.
Missed dose instructions
For daily dosing, if a dose is missed, patients should take the next dose at the usual time. A double dose should be avoided. For on-demand dosing, there is no scheduled regimen, so missing a dose simply means taking tadalafil before the next sexual activity when appropriate.
Price and availability of Cialis in the UK
How much does Cialis cost?
Retail prices for Cialis vary by strength, pack size, retailer and whether the product is branded or generic. On average, branded Cialis 20 mg on-demand tablets may cost between £30 and £60 for a pack of four. Generic tadalafil equivalents can be significantly cheaper, often starting around £10 to £15 for a four-tablet pack.
Why do prices differ?
Prices reflect factors such as manufacturing costs, competition, retailer mark-up, bulk pack discounts and distribution agreements. Generic tadalafil products may be cheaper due to lower development costs and multiple suppliers driving competitive pricing.
| Product | Strength | Pack Size | Approx. Price (GBP) | Type |
|---|---|---|---|---|
| Cialis | 20 mg | 4 tablets | £45.00 | Branded |
| Generic Tadalafil | 20 mg | 4 tablets | £12.00 | Generic |
| Cialis Daily | 5 mg | 28 tablets | £70.00 | Branded |
| Generic Tadalafil Daily | 5 mg | 28 tablets | £22.00 | Generic |
Online vs High-Street pharmacy
Online pharmacies often offer lower prices through bulk purchasing agreements and leaner overheads. NHA Pharmacy provides competitive pricing for both generic and branded tadalafil, with special “buy 3 get 1 free” promotions on bulk orders and seasonal discounts that can lower the cost per tablet.
Cheaper options
If budget is a concern, generic tadalafil at lower strengths can be tapered to achieve an appropriate on-demand dose. Splitting higher-strength generic tablets under pharmacist guidance can further reduce price per milligram.
Generic vs branded Cialis: differences explained
What is a generic medicine?
A generic medicine contains the same active ingredient, tadalafil, at an equivalent therapeutic dose to the branded reference medicine, Cialis. Generics must meet stringent regulatory requirements for bioequivalence, quality, safety and efficacy before UK marketing authorisation.
Inactives and appearance
Generic products may differ from the branded product in non-active ingredients (excipients), tablet shape, color, imprint and packaging design. These differences do not affect the active drug’s performance but may influence patient preference.
Cost considerations
Generic tadalafil is often priced 50% to 80% lower than branded Cialis. Cost savings for patients and the NHS make generics an attractive option when supply is reliable and patient tolerance is established.
Brand loyalty and trust
Some patients prefer the original branded product due to familiarity, perceived reliability or marketing reassurance. Pharmacists can advise on switching to generics and monitor for therapeutic consistency.
Buying and ordering Cialis without prescription online
In the UK, Cialis is classified as a Prescription Only Medicine (POM). However, online pharmacies operating under legitimate Patient Group Direction (PGD) or online prescribing frameworks can supply Cialis without a traditional paper prescription. At NHA Pharmacy, our clinicians assess each order via an online health questionnaire to ensure safety and appropriateness. Approved orders are dispatched with clear dosage instructions and patient information leaflets.
Order process
- Complete the online health questionnaire detailing medical history, current medications and allergies.
- A qualified prescriber reviews responses within hours during working days.
- Approved orders are packed discreetly and shipped with tracked delivery.
- Follow-up support from our pharmacy team is available for queries.
Without prescription means with online assessment
“Without prescription” refers to the convenience of not requiring a GP visit and printed prescription form. It does not mean a lower standard of clinical assessment. All customers receive professional review in compliance with MHRA guidelines.
Cheaper bulk orders
To reduce the price per tablet, customers can purchase larger packs or subscribe to monthly refills with automatic dispatch. Bulk orders often qualify for free shipping and additional loyalty discounts.
Benefits and expected outcomes
- Improved erectile function enabling satisfactory sexual performance.
- Long duration of action (up to 36 hours) offering greater spontaneity.
- Daily dosing option supports frequent intimacy and BPH symptom relief.
- Well-studied safety profile with decades of clinical experience.
- Rapid onset permits use approximately 30 minutes before sexual activity.
Most men experience improved rigidity and firmness compared to baseline within clinical trial observations. Patient satisfaction rates exceed 80% in multiple studies measuring treatment success and partner satisfaction.
Side effects, safety and tolerability
Like all medicines, Cialis can cause side effects, though not everyone experiences them. Most are mild to moderate and resolve without treatment. Common side effects include:
| Headache | Approximately 16% of users |
| Indigestion (dyspepsia) | Approximately 11% of users |
| Back pain | Approximately 8% of users |
| Muscle aches | Approximately 7% of users |
| Flushing | Approximately 10% of users |
| Common cold symptoms | Approximately 4% of users |
Rare but serious reactions
Priapism (painful erection lasting >4 hours) is a medical emergency requiring prompt treatment. Sudden vision loss or hearing impairment are rare but necessitate urgent evaluation. Discontinue tadalafil and seek immediate medical care if these occur.
Safety in special populations
Use in patients over 65 does not require dose adjustment based solely on age, but comorbidities and concomitant medications should guide prescribing. Tadalafil daily is not recommended for patients with severe renal or hepatic impairment without specialist oversight.
Contraindications and warnings
- Concurrent use of nitrates (risk of severe hypotension).
- Hypersensitivity to tadalafil or any excipient in the product.
- Severe cardiovascular disorders where sexual activity poses risk.
- Recent history of stroke or myocardial infarction (within 6 months).
- Uncontrolled arrhythmias or hypotension (BP <90/50 mmHg).
Before purchasing Cialis without prescription, disclose all medications and medical conditions in the online questionnaire to identify any contraindications. Pharmacists may refuse supply if safety cannot be guaranteed.
Drug interactions and precautions
Nitrates and nitric oxide donors
Co-administration of nitrates and PDE5 inhibitors can lead to life-threatening hypotension and is strictly contraindicated.
Alpha-blockers
Concomitant use with alpha-blockers requires careful initiation and dose titration to minimise the risk of symptomatic hypotension, particularly in patients with benign prostatic hyperplasia.
CYP3A4 inhibitors and inducers
Strong CYP3A4 inhibitors (e.g., ketoconazole, ritonavir) can increase tadalafil exposure; dose adjustments or avoidance may be necessary. CYP3A4 inducers (e.g., rifampicin, carbamazepine) can reduce efficacy by accelerating metabolism.
Anti-hypertensives
Caution when co-prescribing with antihypertensives, as an additive blood pressure-lowering effect may occur. Monitor blood pressure and adjust doses accordingly.
Other interactions
Use with guanylate cyclase stimulators, certain protease inhibitors or other PDE inhibitors may require specialist review. Always consult your pharmacist when starting any new medication.
Lifestyle considerations: diet, alcohol and exercise
Dietary factors
Unlike some PDE5 inhibitors, Cialis absorption is not significantly affected by food. High-fat meals may slightly delay Tmax but do not reduce overall bioavailability. Patients can take the tablet with or without meals.
Alcohol consumption
Moderate alcohol consumption does not generally impair tadalafil’s effect. However, excessive alcohol intake can increase the risk of orthostatic hypotension and reduce decision-making capacity during sexual activity.
Exercise and cardiovascular health
Sexual activity is a form of physical exertion. Patients with cardiovascular disease should discuss exercise tolerance and the safety of sexual activity with a healthcare professional.
Smoking and vascular health
Smoking adversely affects vascular function and may reduce the effectiveness of tadalafil. Smoking cessation benefits overall cardiovascular health and erectile function.
Long-term use, tolerance and dependency
Tolerance development
Unlike nitrates, PDE5 inhibitors do not cause pharmacological tolerance in the sense of requiring escalating doses to maintain efficacy. Clinical studies of daily tadalafil for up to one year show sustained effectiveness without dose escalation.
Dependency concerns
Cialis does not produce psychological or physical dependence. However, patients should use the medication appropriately and avoid exceeding recommended doses or frequency.
Periodic review
Men who use Cialis regularly should have periodic reviews with a healthcare professional to assess efficacy, safety and any emerging medical issues. Reviews help optimise treatment plans and detect any contraindications or interactions.
Long-term safety
Data from long-term trials demonstrate an acceptable safety profile over 12 months of continuous use. Common side effects remain stable, and no new safety signals have emerged in extended observations.
