Why is sildenafil prescribed? Sildenafil under the brand name Viagra is prescribed to treat erectile dysfunction by increasing blood flow to the penis during arousal. Sildenafil under the brand name Revatio is often prescribed to help adults with PAH get more exercise by treating their condition.
For PAH: Sildenafil works by relaxing the muscles and opening up the blood vessels in your lungs. This decreases the blood pressure in your lungs. Sildenafil slows down the progression of your illness. It also makes you more able to exercise.
The most effective ED pill for you will vary depending on your needs, health, and other medications you may already be taking.
Talk with your doctor if you’re pregnant or planning to become pregnant. It appears unlikely that this drug will harm a pregnancy. However, this drug should only be used during pregnancy if clearly needed.
Sildenafil oral tablet can interact with other medications, vitamins, or herbs you may be taking. An interaction is when a substance changes the way a drug works. This can be harmful or prevent the drug from working well.
Taking these drugs with sildenafil can cause your blood pressure to drop suddenly to an unsafe level.
For children: This drug isn’t recommended in children younger than 18 years. In one study, children with PAH who took this drug had an increased chance for death.
The kidneys, liver, or heart of older adults may not work as well as they used to. This can cause your body to process drugs more slowly. As a result, a higher amount of a drug stays in your body for a longer time. This raises your risk for side effects.
The main difference between generic sildenafil and Viagra is marketing. The main ingredient in Viagra is sildenafil, meaning that the drugs are essentially the same.
For PAH: Take your dose as soon as you remember. But if you remember just a few hours before your next scheduled dose, take only one dose. Never try to catch up by taking two doses at once. This could result in dangerous side effects.
For people with problems with the shape of their penis: If you have a problem with the shape of your penis, such here as Peyronie’s disease, this drug raises your risk for having an erection that lasts more than 4 hours.
Sildenafil oral tablet is available as the brand-name drugs Viagra and Revatio. It’s also available as a generic drug. Generic drugs usually cost less than the brand-name version. In some cases, they may not be available in every strength or form as the brand-name drug.
