Cialis: Key Information for Irish patients

What you need to know about Cialis

Cialis is prescribed to assist with erectile dysfunction and is a similar medicine to Viagra. It is the trade name of tadalafil, a prescription only treatment. It is what’s known as a PDE-5 inhibitor. PDE-5 stands for Phosphotdiesterase Type 5. There are two other treatments in the same class of pharmaceutical; Levitra (vardenafil) and Viagra (sildenafil).

How does Cialis work?

PDE-5 inhibitors (including Cialis) increase the rate of blood flow into the erectile tissues of a man’s penis when he becomes sexually aroused. Cialis does not act as an aphrodisiac however which means it does not create any form of sexual desire in itself. It only functions when a man is aroused by other stimuli.

How should I take Cialis?

You should take Cialis prior to sexual intercourse. It is effective fairly quickly after taking it—to get the best results you should take it at least 30 minutes before you have sexual intercourse.

Alcohol is known to make Cialis less effective and it’s recommended you drink no more than two units of alcohol when using it.

Never take more than one tablet at a time; in fact you should not take more than one tablet within 24 hours. Nor should you not take Cialis and Viagra or Levitra at the same time or within 24 hours of each other.

How fast does Cialis work?

Normally, Cialis is effective within an hour of taking a pill. It may continue to be effective for up to 36 hours. Of course this does not mean you will have an erection for 36 hours, just that it will be easier to gain and maintain an erection during this period if you become sexually aroused.

How effective is Cialis?

Some men find that Cialis is highly effective in treating erectile dysfunction. Each individual will respond differently to Cialis and a lot depends on what the physical and psychological causes of the problem are and how severe they are. The level of sexual stimulation needed to gain and maintain an erection may also vary from case to case.

If you do not have a positive first time experience with Cialis you should not stop taking it. It may be that there were other reasons that it doesn’t perform as expected including a lack of sufficient sexual stimulation. It’s recommended that you should try Cialis at least 8 times before you seek an alternative treatment or higher dosage.

Does Cialis have any side effects?

Cialis may cause some mild side effects which can vary from person to person. Common issues include facial flushes, headaches, and light-headedness. More rarely, they may include a stuffy nose, a backache or indigestion.

Cialis lasts for longer in the body than Viagra or Levitra. As such side-effects of Cialis may also last for longer than on the other medications for erectile dysfunction.

You should contact us using your patient record if you suffer from side effects when taking Cialis.

If you suffer from any chest pain or you have an erection for a period of more than five hours when taking Cialis you should contact a hospital or medical professional immediately.

Can I take Cialis with other medicines? 

You should not take Cialis in combination with nitrates as this can cause a potentially fatal drop in blood pressure. In particular these are often found in medicines used to treat the condition of angina such as GTN sprays and tablets you put under your tongue. They are also found in some recreational drugs too, in particular “Aromas”, “Poppers” and “Room Odorizers”. Cialis and nitrates taken together can lead to dangerously low blood pressure.

You should not take Cialis in combination with “alpha-blockers”. These include; tamsulosin, terazosin, doxazosin, and alfuzosin. These may also lead to dangerously low blood pressure when combined with Cialis.

If you need to start taking any new medicines you should contact us using your online patient record before you do so.

Does Cialis treat the causes of erectile dysfunction?

No. Cialis relieves the symptoms of erectile dysfunction, but cannot cure the underlying issues that cause the condition. You should review any messages we have sent you about follow up tests to find out what is causing your erectile dysfunction.

However, in some cases if the problem is mainly psychological, the use of Cialis has been known to halt the cycle of failure and/or anxiety that may cause difficulty in gaining or maintain an erection.
