Cialis can last for two daysCialis starts working faster than Viagra, sometimes in 16 minutes, and lasts 24 hours or more.In contrast, Viagra usually works for only four hours after an hour’s delay. As with Viagra, 80% of men with erectile function are able to achieve an erection with Cialis use and three out of four are able to achieve sexual intercourse. But in one Cialis study, 59% of previously impotent men were still able to have sex 36 hours after taking it. The reason is that the body takes four times as long to get rid of Cialis than to eliminate Viagra. The half-life of Viagra (time for blood
levels to fall 50%) is 4 hours compared to 17 hours for Cialis. That means 25% of a Cialis dose is still present in the body after 35 hours, and 12.5% after more than 50 hours. It also means that Cialis will accumulate in the body if taken regularly.

How does Cialis work?Cialis works by blocking an enzyme called phosphodiesterase-5  or PDE-5. This process helps the smooth muscles in the penis to relax and widen, which allows more blood to enter the penis enabling a faster erection.  

Cialis can work for up to 36 hours, although sexual stimulation will be required for it to work. How do i take Cialis?Cialis is taken orally, with or without food, before sexual activity and not more than once daily. The absorption of Cialis is not affected by food, but drinking excessive alcohol when taking Cialis is not advised as the combination may increase your chances of getting dizzy or lowering your blood pressure.Cialis Dosages There are 10 mg and 20 mg pills available. The recommended dose is no more then one pill (10/20mgs) per day.

Cialis is used to treat erectile dysfunction, also known as impotence, in men. This is when a man cannot get, or keep, a hard erect penis suitable for sexual activity.

 Following sexual stimulation, Cialis works by helping the blood vessels in your penis to relax, allowing the flow of blood into your penis. The result of this is improved erectile function. Cialis will not help you if you do not have erectile dysfunction.

 It is important to note that Cialis does not work if there is no sexual stimulation. You and your partner will need to engage in foreplay, just as you would if you were not taking a medicine for erectile dysfunction.

Do not take Cialis if:

You are currently taking any nitrates or amyl nitrite. Nitrates are medicines used in the treatment of angina pectoris (”chest pain”). Cialis has been shown to increase the effects of these drugs. If you are taking any form of nitrate or are unsure tell your doctor.

If you have had an allergic reaction in the past to tadalafil or any of the other ingredients of Cialis. Some of the symptoms of an allergic reaction may include shortness of breath, wheezing or difficulty breathing; swelling of the face, lips, tongue or other parts of the body; rash, itching or hives on the skin.

Do not take Cialis after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering. If it has expired or is damaged, return it to your pharmacist for disposal.

Tell your doctor if you have allergies to any other medicines, foods, preservatives or dyes. For those who are lactose intolerant, be aware that Cialis tablets contain a small amount of lactose (approximately 200mg for the 10mg tablet and 250mg for the 20mg tablet).

 Carefully follow all directions given to you by your doctor or health care professional. They may differ from the information contained in this leaflet.
