Tadalafil (Generic Cialis) Information

Cialis is a popular and effective erectile dysfunction (ED) medicine that was first approved by the U.S. Food and Drug Administration in 2003. Since that time, Cialis has grown in popularity, coming to rival the best-known ED tablet on the market, Viagra. 

When the patent on Cialis ran out in the UK in November 2017, pharmaceutical manufacturers were able to bring the cheaper generic version of Cialis, a medicine called Tadalafil, to UK patients. 

What is generic Cialis (Tadalafil)?

The term ‘generic’ is applied to medicines which have not been produced by the original pharmaceutical company that manufactured them. Generic medicines are not branded and can only be manufactured after the patent on the original medicine has expired. This happened with the erectile dysfunction tablet Viagra – when its patent expired in 2013, the generic medicine Sildenafil, became available.

Generic Cialis is labelled Tadalafil because the active ingredient (the chemical that treats erectile dysfunction) is called tadalfil. In the same way, you might buy a tablet labelled ‘paracetamol’ rather than a branded pain medication.  

Generic Cialis, or Tadalafil, is the same as Cialis in terms of its active ingredient (tadalafil), its effectiveness and side effects. The difference you may see is in the cost, with generic medicines tending to be less expensive.

What is the difference between Tadalafil and Cialis?

The key difference between the two tablets is the pricing. Branded Cialis made by the original manufacturer will be priced higher than Tadalafil.

In terms of effectiveness, there should be no difference at all, as Tadalafil contains the same active ingredient in the same quantities as Cialis. 

If you have taken Cialis before, you may notice a few visible differences between the two. The packaging and tablets for Tadalafil will look different to the packaging and tablets for Cialis, simply because they have been manufactured by a different company.

How does Tadalafil work?

Tadalafil works in the same way as branded Cialis. The active ingredient (tadalafil) is a PDE-5 inhibitor, a chemical that temporarily increases blood flow to the penis. This enables erections for the period in which the chemical is effective. 

One of the reasons ED patients opt for Cialis/Tadalafil over other ED tablets such as Viagra is that the period of effectiveness is much longer. Viagra typically wears off after four to six hours, while Tadalafil can last for up to 36 hours. This does not mean you will have an erection for that period; it simply means that, during this time, you should be able to get an erection whenever you become aroused.

Within 30-60 minutes of taking either Tadalafil or Cialis, you should find that you can get an erection.

How should Tadalafil be taken?

Tadalafil should be taken the same way as Cialis. You should take one Tadalafil tablet, in the dosage prescribed by your doctor, at least 30 minutes before you plan to have sex. Eating beforehand does not typically impact the effectiveness of Tadalafil, however you should try not to drink more than one or two units of alcohol.

You should never take more than one Tadalafil tablet within a 24-hour period, and you should never alter your dosage without talking to your doctor first. It is recommended that you try one type of ED tablet eight times before switching to an alternative treatment.
