Tadalafil tablets are the unbranded, generic version of the well-known Erectile Dysfunction (ED) medication Cialis. Tadalafil tablets tackle ED by increasing the flow of blood to your penis, helping you to both achieve, and maintain, an erection. Because of the expiration of the Cialis patent, Tadalafil (Generic Cialis)  is now available for sale in the UK as a cheaper form of ED medication. 

Tadalafil tablets begin to take effect 30-60 minutes after they have been administered. Once one tablet has been taken, it is then effective for up to 36 hours. This led to Tadalafil tablets being called ‘the weekend pill’, as it lasts for much longer than traditional ED pills like Viagra. 

The active ingredient of Generic Cialis tablets is the drug Tadalafil. Tadalafil helps to increase the flow of blood to your penis by preventing the chemical Phosphodiesterase type 5 from acting within your body. 

This keeps your blood vessels dilated for longer than they would be normally, which then makes it easier for the blood to reach your penis — effectively getting and keeping an erection. 

Tadalafil tablets do not work without sexual stimulation — they will not produce an erection without you being sexually stimulated or ‘turned on’. This is because the drug Tadalafil enhances the chemical messages responsible for producing an erection; it does not, and cannot, fully replace or replicate these messages.  

There are many causes of ED and it affects men of all age and health levels. However, ED has been reported to be a symptom of early stage diabetes, high blood pressure, and poor circulation, while it is also more common in men who are smokers and/or overweight. 

ED can also be caused by stress, smoking, alcohol and fat consumption, and cycling for over 3 hours a day. 

Failing to treat ED can lead to stress, anxiety, depression, and difficulties in your close relationship(s). 

In addition to Generic Cialis/Tadalafil tablets, there are a further ED seven medications that you can purchase online from The Independent Pharmacy. These are: 

No combination of Viagra/Sildenafil, Cialis, Levitra, Spedra or other ED treatment should be used at the same time – you should leave a break of up to 24 hours (36 hours for Cialis/Generic Cialis Tadalafil).

There are also a series of Non-Prescription Alternatives available for treating ED. These include: 

  • Changes to your diet (such as reducing your alcohol and fat consumption)
  • Counselling
  • Lowering your stress levels
  • Stopping Smoking
  • Vacuum Devices (Penis Pumps).
*Prescription medicines are supplied subject to a medical consultation at the discretion of a doctor.

Take ONE Tadalafil tablet per day – no more than one. You should not repeat the dose, or take another ED treatment, within a 36-hour period.

Tadalafil tablets are designed on an ‘as required’ basis, which means that you should only take them when you believe that you require help in achieving and maintaining an erection.  

Tadalafil tablets can be taken either with or without food, but should be taken orally, with water, and swallowed whole when you take them.  

Please be aware that medication affects people who are taking it in different ways – people who take Tadalafil tablets will not necessarily experience any of the known side effects listed below.
