Viagra Instructions
Whether considering Viagra as a treatment for erectile dysfunction or recently receiving a prescription for the medication, understanding basic information about how to use the drug is important for patients.
Doses and Storage
Viagra comes in four different doses: 20, 25, 50, and 100 milligrams. Most men receive the best results when using the 50 milligram dose, although physicians will generally prescribe the lower doses first and see how they work.
The medication should be stored in a room at 77 degrees Fahrenheit to prevent the degradation of the active ingredient.
Taking Viagra Properly
For the best results, men should take Viagra at least one hour but no more than four hours prior to sexual activity. Unless sexual stimulation occurs, an erection will not result even with the medication.
Side Effects
In the trial studies, less than 2% of the tested men suffered from adverse side effects after using Viagra. When these effects did occur, they consisted mostly of mild problems, such as headaches, nasal congestion, urinary tract infections, dizziness, vision problems, or diarrhea.
Vision problems and dyspepsia (indigestion) were side effects that occurred at slightly higher rates in men who were given higher doses of the medication.
Precautions
Men who have been diagnosed with cardiovascular disease may not want to use Viagra. Studies have shown that the medication can cause a drop in blood pressure and that it may increase risks of cardiac problems, particularly when combined with the excitement of sexual activity.
Some men have also suffered from priapism, or an erection that lasts more than four hours. This can cause serious damage to the penis and requires immediate medical attention. This effect occurs in very few users.
