Keeping it simple, tadalafil lasts for up to 36 hours and sometimes longer, and has the longest duration of action of all the PDE5 inhibitors. This compares 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.
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.
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.
Tadalafil 2.5mg and 5mg can be used on a daily basis
Tadalafil is the medical – or generic – name for the Cialis brand of erectile dysfunction medicine. Tadalafil works in a similar way to 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.

We are all familiar with ‘best-before’ and ‘use-by’ dates on food. Medicines are very similarly labelled.
If you look at the packet of your most recent medication, you will see stamped on it somewhere, an expiry date. But what does this expiry date really mean?
Although generally not recommended, we may sometimes choose to eat certain foods beyond their ‘best before’ date. But can we do the same with medicines?
Is it really necessary to throw away, and waste, unused medicines?
Not yet. Champix is the only brand name of the drug varenicline currently available in the UK or the EU. Champix was patented in 2006, and remains under patent until September 2021 in the UK/EU – in the USA it is patented until 2020 under the brand name of Chantix, so a generic cannot be legally sold until the patent expires.
The active medical ingredient in Champix is called varenicline. Varenicline is the generic name of the product.
