One of the less common side effects associated with Viagra is a medical emergency known as priapism. Priapism is a painful erection lasting for more than four hours which requires immediate medical attention and treatment. Priapism may lead to permanent damage if left untreated, including the permanent loss of ability to have an erection. Levitra acts similarly to Viagra regarding possible side effects and onset and duration of pharmacologic action. However, Levitra is available at a lower dose and commonly causes dizziness. The typical recommended starting dose of Levitra is 10 mg and dosages can range from 5 mg to 20 mg depending on desired response and adverse reactions. Cialis differs from both Viagra and Levitra with regard to onset and duration of action. With treatment with Cialis, improvement in erectile function is possible for anywhere from 24 to 36 hours after administration of a dose, significantly longer than with Viagra. In addition, Cialis typically has a quicker onset of action and begins to work within approximately 30 minutes. Similar to Levitra, the recommended starting dose for Cialis, as needed, is 10 mg. Doses may range from 5 mg to 20 mg depending on efficacy and patient tolerability. tentex royal benefits

As in the other titration studies, patients were started on 50 mg and allowed to adjust the dose up to 100 mg or down to 25 mg of Viagra; all patients, however, were receiving 50 mg or 100 mg at the end of the study. There were highly statistically significant improvements on the two principal IIEF questions (frequency of successful penetration during sexual activity and maintenance of erections after penetration) on Viagra compared to placebo. On a global improvement question, 57% of Viagra patients reported improved erections versus 10% on placebo. Diary data indicated that on Viagra, 48% of intercourse attempts were successful versus 12% on placebo.
