Tadalafil is a drug used to treat erectile dysfunction. It is a type of PDE5 inhibitor. Tadalafil is a generic or drug name – ‘Cialis’ is a branded form of tadalafil.

One question men frequently ask when trying to choose a PDE5 inhibitor, is how long does it last?

Keeping it simple, tadalafil lasts for 36 hours and sometimes longer, and has the longest duration of action of all the PDE5 inhibitors. This compares for example to sildenafil (Viagra) which lasts for around 4 hours.

In addition, absorption of tadalafil is not affected by food, so it can be taken at any time before, during, or after a meal.


36 hours – really?

Yes, although this does not mean a continuous erection for 36 hours. Like all PDE5 inhibitors, tadalafil requires sexual stimulation to work – ie: you only get an erection when you want to.

Once daily tadalafil

Once daily tadalafil 5mg

Tadalafil is the medical – or generic – name for the Cialis brand of erectile dysfunction medicine. Tadalafil works in the same way as sildenafil (Viagra), however whereas sildenafil lasts for around 4 hours, tadalafil remains active for up to 36 hours, hence why it is sometime called the weekend pill. This does not mean you will have an erection for 36 hours, only when required, eg: when sexually aroused.

Most men take tadalafil as and when they need it 30 minutes or more before sexual activity. The usual starting dose is tadalafil 10mg, which – depending on effectiveness – may be increased to 20mg or decreased to 5mg.

What’s the difference between tadalafil and other ED treatments?

Happy couple after man takes tadalafilOne in ten men will experience sexual problems at some point. It’s fair to say that erectile dysfunction (ED) is a very real problem and can affect men across the spectrum. It doesn’t matter if you are gay, straight or bisexual – erectile dysfunction doesn’t discriminate. ED, or impotency, does tend to affect more mature males, but again, that’s not a given. A younger man going through a particularly stressful time or suffering from a medical problem may be just as likely to suffer from ED.

So, we are well aware of the problem but what can be done about erectile dysfunction? There are numerous treatments available. These include counselling or sex therapy, using medication (such as Viagra or Cialis), using equipment to assist (eg a vacuum pump), undergoing surgery, injections, implants and suppositories, or trying out alternative therapies.

Viagra Connect over the counter

Sildenafil from 97p per tablet

The UK medicines regulator today (28 Nov 2017) approved an application to make Viagra available over the counter in pharmacies (‘P’ medicine classification). See MHRA reclassifies Viagra Connect tablets to a Pharmacy medicine.

Pfizer’s new product will be called Viagra Connect and will contain 50mg of Viagra (sildenafil) in packs of 4 and 8 tablets and is expected to be available Spring 2018. Pricing is unconfirmed but likely to be around £5 per pill.

The MHRA’s decision follows the expiry of Pfizer’s exclusive patent for Viagra in 2013, after which other pharmaceutical companies were permitted to supply their own Sildenafil tablets and prices were slashed. More recently (14 November 2017) the patent expired for Cialis (another popular drug for erectile dysfunction), and the price of generic Cialis (‘Tadalafil’) is significantly lower. Read in full
