Tadalista Professional is a prescription-only medicine containing Tadalafil 20mg. It belongs to the phosphodiesterase type 5 (PDE5) inhibitor class. Prescribed for adult men, this medicine supports the ability to achieve and sustain an erection when sexual stimulation is present. A sublingual tablet form is how this medicine is supplied, dissolving under the tongue for absorption. Before starting this medicine, guidance from a qualified doctor or pharmacist should always be sought.

Mechanism of Action
PDE5 — the enzyme known as phosphodiesterase type 5 — is targeted and inhibited by Tadalafil. It is through this inhibition that the medicine’s therapeutic effect is produced. Because PDE5 is inhibited, cyclic GMP — a naturally occurring chemical — is able to build up within the body.
Smooth muscle tissue within the penile blood vessels is relaxed through the action of cyclic GMP. Because smooth muscle tissue becomes relaxed, a greater volume of blood is able to flow into the penile tissue. This widens the vessels and increases blood flow during sexual stimulation.
Sexual stimulation remains necessary, as an erection is not produced by this medicine on its own. Sexual arousal remains necessary for the medicine to take effect.

MHRA Yellow Card Scheme
Suspected side effects of Tadalafil — and all other medicines — can be reported by both patients and healthcare professionals through the MHRA Yellow Card scheme at yellowcard.mhra.gov.uk. Each report submitted contributes to the ongoing safety surveillance of medicines throughout the UK.
Safety Advice
Drug interactions are an important consideration with Tadalafil. Because nitrate medicines are frequently used to manage angina and other heart conditions, combining them with Tadalafil is strictly contraindicated.
This combination can cause a severe and potentially life-threatening drop in blood pressure.
An interaction may also occur with alpha-blockers, which are prescribed for high blood pressure or prostate-related conditions.
A full list of all current medicines — including over-the-counter products, herbal remedies, and supplements — should always be shared with your doctor and pharmacist before starting treatment.
Alcohol consumption should be limited whilst taking Tadalafil. Consuming alcohol alongside Tadalafil can heighten the likelihood of dizziness, flushing, and a drop in blood pressure, and is therefore best avoided. Your doctor or pharmacist can advise on safe limits based on your individual circumstances.
Medical conditions to disclose before starting this medicine include:
- Known heart disease
- A recent history of heart attack or stroke
- Severely low or high blood pressure
- Liver or kidney disease
- Retinitis pigmentosa
- Peyronie’s disease
- Sickle cell anemia
- Multiple myeloma
- Leukemia
- Active peptic ulcer and bleeding disorders
These conditions may affect whether Tadalafil is appropriate or safe for you.
Use in women is not indicated for Tadalista Professional. This medicine is not indicated for use during pregnancy or whilst a mother is breastfeeding. It is authorized solely for use in adult men.
Because Tadalafil can cause dizziness in some individuals, driving and the use of heavy machinery should be approached with care. If any such effects are felt after taking this medicine, driving or operating machinery must be avoided until they pass.
It is important to note that sexually transmitted infections are not prevented by taking this medicine.
This includes:
- HIV
- Hepatitis B
- Gonorrhea
- Syphilis
Patients should use appropriate protection independently.
Accessing Treatment Responsibly
Tadalista Professional holds prescription-only medicine (POM) status under UK law, meaning it cannot be obtained without a valid prescription. Before this medicine is dispensed, a registered UK prescriber must issue a valid prescription. Dispensing this medicine without a valid prescription is not permitted under any circumstances.
Obtaining prescription medicines from unregulated online sources carries serious risks. Counterfeit or substandard medicines may contain incorrect dosages or harmful substances.
Do not self-prescribe or attempt to obtain this medicine without a consultation. Whether Tadalafil is suitable for your individual circumstances is best determined by speaking with your GP or a registered prescriber.
Frequently Asked Questions
Q: Is Tadalista the same as Cialis?
A: Tadalista contains the same active ingredient as Cialis Tadalafil. Both work identically. However, Cialis is the UK-licensed brand. Before making any change to your prescribed medicines, your doctor or pharmacist should always be consulted first.
Q: How many hours is tadalafil effective for?
A: The effects of Tadalafil can last for up to 36 hours, though this duration varies from person to person — a characteristic that has led to it being commonly referred to as the weekend pill.
Q: Is tadalafil stronger than Viagra?
A: Tadalafil and Viagra work differently. Compared with other treatments in the same class, a notably longer duration of action — up to 36 hours — is offered by Tadalafil. Viagra acts faster but wears off sooner. Your doctor will advise which suits you best.
