Information on Cialis

Cialis - what kind of medicine is it?

Cialis is in the same family of medicines as Viagra and is prescribed to help tackle impotence, which is also known as erectile dysfunction. Cialis is the trade name of a prescription only medicine whose scientific name is tadalafil. It is one of a class of medicines known as PDE-5 (Phosphodiesterase type 5) inhibitors. The other two medicines in this class are Viagra (sildenafil) and Levitra (vardenafil).

How does it work?

Cialis and the other PDE-5 inhibitors can help men with impotence (erectile dysfunction) by increasing the blood flow into the erectile tissue in the penis when you are aroused.

Cialis is not an aphrodisiac because it can only work if you are already sexually aroused. Cialis will not create any sense of arousal itself or increase your sex drive.

How do I take it?

  • Cialis should be taken at least 30 minutes before sex.
  • You should not drink more than one or two units of alcohol as this will make Cialis less effective
  • You should never take more than one Cialis tablet at a time and not take more than one tablet in 24 hours.
  • Cialis should not be taken within 24 hours of taking Viagra (Sildenafil) or Levitra.

 

How quickly does it work?

On average, Cialis becomes effective in under an hour after taking a tablet. Cialis can remain effective for up to 36 hours. This does not mean that your erection will last that long – simply that you will have the ability to attain an improved erection for that period of time.

How effective is it?

Cialis has been shown to be effective at helping some men attain and sustain better erections. How a particular man responds to Cialis very much depends upon the underlying cause of his impotence, the severity of any underlying cause and his degree of sexual stimulation.

If Cialis does not improve your erection the first time you take it, do not give up. The reason it did not work may have been that you were not sufficiently aroused. In most circumstances, it is advised that you should not try an alternative treatment or higher dose until you have tried Cialis at least eight times.

Are there any side effects?

  • Like all medicines, Cialis can have side effects. Cialis's common side effects are headache, light headedness and facial flushing. Less frequently, men taking it have reported indigestion, a stuffy nose and backache. As Cialis has a longer duration of action than Viagra or Levitra then the side effects may last longer than these other treatments for erectile dysfunction.
  • If you experience any side effect from taking this medicine please contact us via your online patient record.
  • If you experience any chest pain when using Cialis or your erection lasts for longer than five hours then contact the emergency services or attend your local Accident and Emergency Department straight away.

 

What if I am taking other medicines?

  • Nitrates: you must not take Cialis if you are taking nitrates. These are present in some medicines to treat angina and recreational drugs such as “Poppers”, “Aromas” or “Room Odorisors”. If you combine nitrates with Cialis your blood pressure can drop dangerously low.
  • Alpha blockers: you must not take Cialis if you are taking alpha-blockers such as alfuzosin, doxazosin, tamsulosin or terazosin. These can also cause a dangerous drop in your blood pressure when combined with Cialis.
  • If you start taking any new medicines then please seek guidance from us by sending us a message via your online patient record.

 

Does Cialis treat the underlying causes of impotence?

Cialis will not resolve any underlying physical cause of your erectile dysfunction. As erectile dysfunction is often a symptom of other underlying conditions it is important that you look at the previous messages we have sent. You should be able to see which follow-up tests are recommended in your case.

If the cause of your impotence is primarily (non organic) psychological, Cialis may help to break the cycle of anxiety and failure associated with being unable to achieve a satisfactory erection.
