Cialis

Cialis is an oral medication used for the treatment of erectile dysfunction, or ED. A specified dose of Cialis should be taken once a day and 24 hours are supposed to pass between two pills as the drug remains in the bloodstream all this time. In case you experience painful erection that lasts for longer than 4 hours it’s important to contact your doctor or seek help in any medical facility. It’s not recommended to take Cialis with alcohol as it is also considered to be a mild vasodilator, so the combination may increase the blood-pressure-lowering effects. Substantial consumption of alcohol may lead to an increase in heart rate, dizziness and headache.

In general, Cialis is tolerated better than Viagra and its side effects are often milder and do not last for a long time. In comparison with Viagra the percentage of color vision problems in Cialis is very low – just 0.1%, at the same time Cialis stays in the blood stream for quite a long time – over 17.5 hours of half-life. In less that 2% of all cases such side effects as fatigue, chest pain, hypotension, dizziness, sweating, nausea and vomiting, sudden decrease of hearing or its loss, spontaneous penile erection have been reported.
