Revatio works by relaxing blood vessels and improving blood flow in the penis, causing an erection.
Revatio is a medication used for the treatment of pulmonary hypertension (an increase in blood pressure in the pulmonary artery, pulmonary vein, or pulmonary capillaries, together known as the lung vasculature, leading to shortness of breath, dizziness, fainting, and other symptoms) in order to improve exercise ability.
The drug relaxes blood vessels, which allows them to transfer more blood and oxygen, reducing pulmonary blood pressure. Its active substance is sildenafil, the same as in Viagra. That is why Revatio can be used in the treatment of men’s health.
Dosage and direction
Take one Revatio tablet of 20 mg three times a day, with or without food. Each dose should be divided by 4-6 hours. Regular intakes of the medication separated by equal time periods are preferable.
Before starting to take Revatio, notify your doctor if you have a history of such diseases as heart attack, stroke, irregular heartbeat, or chest pain (angina), high or low blood pressure, blood vessel disorders, problems with blood circulation, retinitis pigmentosa, disease of the liver or kidney, deformation of the penis, sickle cell anemia, porphyria, or cancer of the blood cells or bone marrow, stomach ulcers, or stomach bleeding.
Pulmonary vasodilators like Revatio may significantly worsen the cardiovascular status of patients with pulmonary veno-occlusive disease.
Revatio is contraindicated in children younger than 12 years of age, in patients who are taking any medications that contain organic nitrates, and in those who are hypersensitive to the medication and its components.
Revatio is mostly well tolerated, but side effects may occur such as fever, flushing, headache, muscle aches, nasal infection, nosebleeds, shortness of breath, sleeplessness, sinus infection, upset stomach. In case of serious and persisting adverse effects, call your doctor immediately as you may need immediate medical help.
Revatio should not be co-administered with any drugs which contain sildenafil (Viagra, Kamagra), Tadalafil 20mg (Erectalis), organic nitrates, antifungal drugs such as ketoconazole and itraconazole Ritonavir (an anti-HIV drug).
Inform your doctor about all medications and herbal products you are taking, especially about alpha-blockers such as doxazosin, barbiturates, Bosentan, Carbamazepine, Rifabutin, Rifampin, Phenytoin, and vitamin K antagonists, as correction of your Revatio dose may be needed.
If you missed a dose, take it as soon as you remember. If it is almost time for your next dose, just skip it and return to your regular schedule. Do not try to make up for the missed dose by taking two doses at once.
Symptoms of overdose are similar to those seen at lower doses, but rates and severities are increased. If you think that you took too much of this medication, you should seek immediate medical help.
