The active ingredient in Cialis, Tadalafil is a phosphodiesterase type 5 inhibitor. This class of medicines are used as a treatment for erectile dysfunction, and work by preventing the action of a chemical in the body called phosphodiesterase type 5.

Tadalafil can be very effective as a treatment for erectile dysfunction – more commonly referred to as impotence. Although it can act in as little as 30 minutes, tadlafil can also be effective for up to 36 hours, meaning that if things turn intimate, you can always be ready.

Many people try to self-medicate with these types of drugs – after all, this can be an embarrassing subject to talk about – but there are several reasons why you should always talk to your doctor if you have erectile dysfunction:

  • There are various causes – this can sometimes be a symptom of an undiagnosed disease such as diabetes, high blood pressure, or high cholesterol. You doctor needs to figure out the cause.
  • These types of medications are strong and can have serious side effects.
  • Products of this type bought via the internet can be either ineffective (not containing the ingredients they claim) or even dangerous, with impure ingredients.

Thus if you have any concerns at all about erectile dysfunction or impotence, talk to your doctor first to get a proper diagnosis and effective treatment.
