Viagra is a prescription medication used to treat erectile dysfunction in adult men. It works by increasing blood flow to the penis during sexual stimulation, making it easier to get and maintain an erection.

Viagra contains sildenafil citrate, which belongs to a class of medications known as PDE5 inhibitors. These medications relax blood vessels and improve circulation when an erection is triggered. Viagra does not cause an erection on its own. Sexual stimulation is still required for the medication to work.

Most people take Viagra about 30 to 60 minutes before sexual activity. Its effects typically last up to four hours. Viagra is available in multiple strengths, including 25 mg, 50 mg, and 100 mg, depending on what is prescribed by a doctor.

At Canada Drug Warehouse, patients can order Viagra from a Canadian pharmacy using a valid prescription. Both brand-name Viagra and generic sildenafil are available. Many patients choose generic sildenafil because it contains the same active ingredient, works the same way, and costs significantly less.

Brand-name Viagra and generic sildenafil contain the same active ingredient and work the same way in the body. For most patients, generic sildenafil provides the same effectiveness, onset time, and duration as brand-name Viagra.

The primary difference is cost. Generic sildenafil is significantly less expensive, which makes it the more common choice for long-term use. Generic Viagra has been available in Canada since 2012 and in the United States since 2017, after the original Viagra patent expired.

Some patients may still choose brand-name Viagra if their doctor recommends it or if they have had a better experience with the branded version in the past. Both brand-name Viagra and generic sildenafil require a valid prescription and are dispensed through regulated pharmacies.

For patients looking to buy Viagra online from Canada, choosing generic sildenafil is often the most cost-effective option without sacrificing effectiveness.
