Tadalafil is a prescription medication commonly used to treat erectile dysfunction (ED) — a condition where a man has difficulty achieving or maintaining an erection firm enough for sexual activity. It’s also known under the brand name Cialis, and generic versions such as Tadalafil tablets are widely available in the UK.
Tadalafil belongs to a group of medicines known as PDE5 inhibitors, which work by improving blood flow to the penis during sexual stimulation. This makes it easier to get and keep an erection.
The main use of Tadalafil is for erectile dysfunction (ED).
It can also be prescribed for benign prostatic hyperplasia (BPH) — an enlarged prostate — and pulmonary arterial hypertension (PAH), though ED remains its most common indication.
Tadalafil works by blocking an enzyme called phosphodiesterase type 5 (PDE5).
Here’s what that means in simple terms:
Tadalafil does not cause an erection on its own — sexual stimulation is still required for it to work.
Tadalafil starts working within 30 minutes after taking it.
Unlike some other ED treatments, it can remain effective for up to 36 hours, which is why it’s often referred to as the “weekend pill.”
This doesn’t mean you’ll have a continuous erection for 36 hours — rather, you’ll have an increased ability to achieve an erection naturally during that period when sexually aroused.
Tadalafil can be taken in two main ways, depending on lifestyle and preference:
1. On-Demand Tadalafil
2. Daily Tadalafil
Your doctor or prescriber will advise which Tadalafil dosage best suits your needs.
Tadalafil is one of the most popular and effective treatments for ED in the UK — and for good reason:

Tadalafil can be taken by most adult men experiencing erectile dysfunction, as long as it’s prescribed by a healthcare professional.
However, it may not be suitable if you:
Always complete a health assessment before ordering to ensure Tadalafil is safe for you.
Like all medications, Tadalafil can cause side effects, although not everyone experiences them.
Most are mild and short-lived:
Seek medical advice if you experience chest pain, sudden vision or hearing loss, or an erection lasting longer than 4 hours.
Medication | Onset | Duration | Best For |
---|---|---|---|
Tadalafil | 30–60 mins | Up to 36 hrs | Flexibility & spontaneity |
Sildenafil (Viagra) | 30–60 mins | 4–6 hrs | Occasional use |
Vardenafil | 30 mins | 4–6 hrs | Faster onset for some users |
The standout features are that Tadalafil is long lasting and provides the option for daily use, making it ideal for men who prefer not to plan around medication timing.
