Viagra is a well-known medication for treating erectile dysfunction, and is classified as a PDE-5 inhibitor. This drug is the flagship product of the American pharmaceutical company Pfizer, and has been available on the market for several decades now. The active ingredient of Viagra and its numerous generics, which are now produced by a variety of pharmaceutical companies, is Sildenafil.

Men who use Viagra to treat their erectile dysfunction typically have positive experiences with the medication. The drug helps to achieve a stable and long-lasting erection by increasing blood flow to the penis. A vast majority of men who take cheap Viagra are satisfied with the results, and continue to use the medication to maintain a healthy sex life.

Viagra is highly effective at treating erectile dysfunction, and can produce an erection in as little as 30 minutes after taking the medication. The effects can last for up to 4 hours, which makes it a popular choice among men who want to be able to engage in sexual activity without having to plan too far in advance. However, it's important to remember that Viagra is not a stimulant and only works if there is sexual desire or stimulation of erogenous zones.

Viagra is available in dosages of 25, 50, and 100 mg of Sildenafil. The most commonly prescribed dosage is 50 mg, but your doctor may adjust your dosage depending on your individual needs.

There are two main types of Viagra therapy: on-demand and continuous therapy. With on-demand therapy, the medication is taken about 30 minutes before sexual activity. With continuous therapy, the medication is taken daily at a lower dosage, typically 25 mg or 50 mg. This type of therapy is recommended for older men who have erectile dysfunction and also suffer from other conditions, such as high blood pressure or diabetes.

It's important to note that taking Viagra with food can slow down the absorption of the medication, so it's best to take it on an empty stomach. Drinking alcohol can also affect the medication's effectiveness and should be avoided or limited while taking Viagra.

Viagra is generally well-tolerated by patients, but like any medication, it can cause side effects. Some of the most common side effects include headache, facial flushing, nasal congestion, and indigestion. These side effects are usually mild and go away on their own. If you experience any severe side effects, such as chest pain or vision changes, seek medical attention immediately.
