What is Viagra?
Viagra is a well-known prescription drug used to treat erectile dysfunction, also known as ED. It contains the active ingredient sildenafil. Sildenafil belongs to a class of drugs called phosphodiesterase type 5 (PDE5) inhibitors. This medication helps men achieve and sustain an erection sufficient for sexual activity. It is one of the most widely recognized treatments for ED worldwide. Viagra is also approved to treat pulmonary arterial hypertension (PAH). PAH is a condition involving high blood pressure in the arteries of the lungs. It can improve exercise ability in adults with this condition.
How does Viagra work?
Viagra works by increasing blood flow to the penis, which helps a man get and keep an erection. The active ingredient, sildenafil, blocks an enzyme called PDE5. When this enzyme is blocked, another substance called cGMP increases. This substance relaxes the smooth muscles and blood vessels in the penis. During sexual arousal, this relaxation allows more blood to enter. The increased blood flow results in a firm erection. For pulmonary arterial hypertension, this same mechanism relaxes blood vessels in the lungs. This lowers the blood pressure in the lungs and reduces strain on the heart.
Who is Viagra for?
Viagra is for adult men who have been diagnosed with erectile dysfunction. It is suitable for those who consistently find it difficult to get or maintain an erection. The medication is also intended for adults diagnosed with pulmonary arterial hypertension. Patients must have a prescription from a qualified healthcare provider. The provider will assess your health history to ensure it is safe for you. It is not for women, children, or anyone taking certain conflicting medications like nitrates. A doctor can determine if Viagra is the right choice for your specific needs.
Dosage and administration
Viagra should always be taken exactly as prescribed by your doctor. The recommended starting dose for erectile dysfunction is usually 50 mg. It should be taken about one hour before sexual activity. Your doctor may adjust the dose to 25 mg or 100 mg based on your response. For older adults over 65, the typical starting dose is 25 mg. Do not take more than one dose in 24 hours. For pulmonary arterial hypertension, the dose is typically 20 mg taken three times a day. You can take Viagra with or without food, but a high-fat meal might delay its effects.
Side effects
Viagra is generally safe, but like all medications, it can cause side effects. Most men do not experience significant problems. Common side effects are often mild. They include headaches, flushing in the face, and an upset stomach. Some people may also experience nasal congestion, back pain, or dizziness. Changes in vision, like a blue tinge, are also possible. More serious side effects are rare but require immediate medical attention. These include an erection that lasts longer than four hours (priapism). Sudden vision or hearing loss is another serious but rare side effect. If you have chest pains or an allergic reaction, seek emergency help.
