Revatio or the generic Sildenafil is a type of medicine known as a phosphodiesterase type 5 inhibitor (PDE5). Revatio may be prescribed to treat pulmonary arterial hypertension (PAH). Revatio improves the ability to exercise and can help lessen symptoms and slow down worsening changes in your physical condition.
PAH is a disease that affects the heart and lungs; it is often referred to as high blood pressure of the lungs. When someone has PAH, the pulmonary arteries become narrow or blocked and the heart must work harder to pump blood through the lungs. The heart fails to keep up over time and less blood flows through the lungs to become oxygenated. The resulting dizziness, trouble breathing and tiredness are symptoms of PAH.
Your doctor may give you a prescription to buy Revatio or the generic Sildenafil if you have been diagnosed with PAH. Revatio increases the levels of one of the chemicals in the cells that line the blood vessels in the lungs. This helps the blood vessels to relax so blood and oxygen can flow more freely.
The generic alternative is not manufactured by the company that makes the brand product.
As with any drug, you may experience side effects when taking Revatio or generic Sildenafil. The most common side effects reported include headache, upset stomach, diarrhea, and trouble sleeping. You should consult your doctor before you buy Revatio to familiarize yourself with possible side effects and check for potential drug interactions if you are taking any other medications.
