    Sildenafil revatio 20 mg oral tab


    Sildenafil is used to treat male sexual function problems (impotence or erectile dysfunction-ED). In combination with sexual stimulation, sildenafil works by increasing blood flow to the penis to help a man get and keep an erection. This drug does not protect against sexually transmitted diseases (such as HIV, hepatitis B, gonorrhea, syphilis). Consult your doctor or pharmacist for more details. Read the Patient Information Leaflet provided by your pharmacist before you start taking sildenafil and each time you get a refill. If you have any questions, ask your doctor or pharmacist. To treat erectile dysfunction-ED, take this drug by mouth as directed by your doctor, usually as needed. Take sildenafil at least 30 minutes, but no more than 4 hours, before sexual activity (1 hour before is the most effective). A high-fat meal may delay how quickly the drug begins to work. where can i buy doxycycline hyclate When a man is sexually excited, the penis rapidly fills with more blood than usual. With this extra flow of blood, the penis then expands and hardens. After the man is done having sex, this extra blood flows out of the penis back into the body. In an opposite extreme situation, if an erection lasts for a long time (more than 6 hours), it can permanently damage your penis. You should call a doctor immediately if you ever have a prolonged erection that lasts more than 4 hours. Therefore sexual activity may not be advisable for people who have heart problems. Before you start any treatment for erectile dysfunction, ask your doctor if your heart is healthy enough to handle the extra strain of having sex. If you have chest pains, dizziness or nausea during sex, stop having sex and immediately tell your doctor you have had this problem. This is called erectile dysfunction if it becomes a frequent problem. Erectile dysfunction is a serious problem that can affect both the young and the old, involving psychological causes in some cases.

Erectile dysfunction, defined today as the inability to attain and maintain an erect penis with sufficient rigidity for sexual intercourse, has become an increasingly common complaint that affects 140 million men worldwide. So Viagra stands out as the pioneer of drugs that treat erectile dysfunction, for twenty years. Sildenafil citrate was the first oral agent to be introduced for the treatment of erectile dysfunction, thanks to the researchers from Pfizer. Sildenafil is the active substance of Viagra, while Viagra is the commercial name. Teva’s generic Viagra has launched already in December 2017 in the United States.
