Levitra is also sometimes used as a treatment for premature ejaculation, significantly increasing the duration of sexual intercourse before ejaculation.
Dosage: The usual starting dose is 10mg taken 1 to 2 hours before an erection is required. This equals to about 50mg of Viagra. Levitra should not be taken more than once a day.
Side Effects: congestion, headache, dizziness, muscle pain.
If you experience prolonged and painful erections (a condition called a priapism) or the erection lasts more than 4 hours, you should visit a doctor immediately! If left untreated this can cause permanent damage to the penis.
