Sildenafil, popularly known as generic Viagra at online Canadian pharmacy, is an exact analog of the branded medication indicated for the treatment of the impaired erectile function in men. Generic Viagra helps men recover their sexual prowess by enhancing the balance of certain chemicals that are in charge of smooth muscle relaxation and penile blood vessel dilation. As a result, the penis is properly supplied with blood and remains erect for a long enough time to give the man plenty of opportunities to engage in sex.

Things You Should Know Before Your Take

Take generic Viagra strictly as advised by your physician; do not increase its dose or administration frequency as there an increased risk of adverse and life-threatening side effects. Do not overeat before you take generic Viagra as it may impede the absorption of the drug substance and consequently decrease its overall effectiveness. Avoid consuming alcohol when on Viagra since it not only reduces the efficiency of the medication but also makes the risk of side effects much higher and their manifestation much more severe. Taking Viagra with grapefruit or grapefruit juice will send your blood levels of sildenafil sky-high. While it might give you a more robust erection, the aftereffects will be much more troublesome and unpleasant.

Is a Prescription Required to Purchase Generic Viagra?

It pretty much depends on the legislation of the country, in which you are buying your generic Viagra. In the US, Canada, and most European countries, both generic and branded Viagra are only legally sold to patients who have a valid prescription since it means that they have been to a licensed doctor and had their condition correctly diagnosed before they decided to buy the drug.

However, today many bogus online pharmacies operating from abroad offer their US, Canadian, and other customers to buy generic Viagra over-the-counter. Doing so is extremely dangerous, seeing as they are distributing medications of unknown origins to customers for whom the suitability of the drug has not been medically proven.

Whether you are buying your generic Viagra from a local pharmacy or Canadian pharmacy, make sure it is a trusted and reputable store that takes the law very seriously and always puts your safety first by asking you for a legitimate doctor’s prescription.

Which Dose Strengths of Generic Viagra Are There?

The choice of generic Viagra Canada dose strengths is much broader than what the branded drug has and ranges anywhere from 25mg to 200mg of sildenafil per tablet. Based on your medical history, the severity of your condition, and other factors, your doctor will choose the most suitable amount of the drug that will produce excellent results without compromising your health.

Viagra 25mg is the lowest starting dose given to new patients to see how they respond to the treatment and check their sensitivity to sildenafil. It may work very well and be sufficient for patients with mild erectile dysfunction.

Viagra 50mg is the most frequently prescribed amount of the drug that is well-tolerated and effective for the majority of patients with mild-to-moderate ED symptoms.

Viagra 100mg is the dose of this drug usually given to patients whose ED symptoms range from moderate to severe. It is often prescribed to men in whom lower-dose Viagra did not work well enough.

Viagra 150mg has a strengthened formula designed to help men with severe and very severe forms of erectile dysfunction. This amount of sildenafil is not considered safe for and should only be taken when your doctor thinks it is the best available treatment option for you.

Viagra 200mg is the highest possible dosage of this medicine. The unsupervised use or self-administration of 200 milligrams of sildenafil is highly unadvised as it may put your life at risk. Men who purchase generic Viagra 200mg usually find it safer to cut the pill in two or four parts. Do not use it if you are over 55 years old or have any coexistent problems with your heart or health in general.
