Viagra is a commonly known drug that is prescribed to treat problems associated with erectile dysfunction (ED). Erectile dysfunction is a common type of male sexual dysfunction, and it is defined as the persistent inability to attain and maintain an erection. ED becomes more common as you get older; it affects as many as 30 million men worldwide. Viagra generic is also available and it is sold under its active ingredient name, Sildenafil. This Sildenafil generic alternative version contains the same active ingredients as the brand-name, hence their equivalent effectiveness.

Sildenafil, the active ingredient in Viagra, is also used to treat pulmonary arterial hypertension (PAH), which is a rare type of high blood pressure occurring between the heart and lungs. This medication relaxes the blood vessels within the lungs which then increases the blood supply to the lungs and reduces the workload of the heart.

How does Viagra work?

When a man is sexually excited, his body’s normal response is to increase blood flow to his penis to produce an erection, but when he has ED, he is unable to achieve this. Viagra or Sildenafil helps men with ED by enhancing the erectile response when they are aroused. This medication belongs to a drug class known as PDE-5 (Phosphodiesterase type-5) inhibitor, which relaxes muscles and improves blood flow in particular areas of the body. In combination with sexual stimulation, this medication can increase the blood flow to the penis, which can help men get and maintain an erection. The side effects of Sildenafil or Viagra do not include increased sexual desire; it does not provide an instant erection without physical stimulation.

Viagra or the Sildenafil generic come in tablets for oral administration. The Viagra dosage available that can be purchased online come in the following strengths: 25mg, 50mg, and 100mg. Your doctor will take into account potential drug interactions, your age, the severity of your erectile dysfunction and any previous experience you have had with Viagra or the Sildenafil generic to determine which Viagra dosage is most appropriate.

You can buy Viagra to be used in conjunction with healthy lifestyle changes to help manage and prevent physical and psychological causes of ED.

Before taking your prescribed Viagra dosage, read all the instructions and paper work that is given to you by your pharmacist. Take the Viagra or Sildenafil dosage orally 30 minutes to an hour before sexual activity.

Many factors can influence how long Viagra takes to start working. In general, Viagra takes about 30 minutes to produce noticeable effects. But your diet, your overall health, and the medications you’re taking, underlying conditions, and much more can all affect the amount of time this medication takes to work in your body and how long it lasts.
