Generic Viagra, an analogue of regular Viagra at Canadian pharmacy, with the active substance Sildenafil. It’s essential to obtain a prescription for its safe use. At its core, Sildenafil citrate, operates by targeting and inhibiting the PDE5 enzyme. With this enzyme in check, blood vessels within the penis undergo dilation, leading to an enhanced blood flow. This physiological alteration amplifies a men’s ability to reach and retain an erection, especially when accompanied by sexual stimulation. Although VIAGRA is used occasionally, nitrates must never be used. Nitrates are found in many prescription medicines that are used in the treatment of angina pectoris (chest pain due to heart disease), such as nitroglycerin, isosorbide mononitrate, or isosorbide dinitrate. If you do not understand what nitrates are, or are unsure about whether a medication you are taking is a “nitrate”, ask your doctor or pharmacist.If you take VIAGRA with nitrate-containing medicines or any other nitrates (e.g., amyl nitrite “poppers”), your blood pressure could suddenly drop to a life-threatening level. You could get dizzy, faint, or even have a heart attack or stroke.

Common complaints include headaches, facial flushing, a tumultuous stomach, or a stuffy nose. On the rarer side of the spectrum, events like sudden vision or hearing impairment can manifest. Alcohol consumption may decrease the ability to get an erection. If you are taking VIAGRA and experience temporary, decrease, or permanent loss of vision, stop taking VIAGRA and call your doctor.

How do you choose?

While sildenafil citrate reigns as the primary functional element in Viagra, giving it its potent PDE5 inhibitory effects, it doesn’t work alone. Various other components, which can vary depending on the drug manufacturer, come into play. These additional ingredients are meticulously chosen to craft the pill and optimize its absorption in the human body. For most men venturing into Viagra, a 50mg dose serves as the standard starting point, ideally consumed around an hour before any planned sexual activity. Yet, the human body’s response can be diverse. In case of chest pain occurring during or after sexual activity you should not use nitrates but you should seek immediate medical assistance. Sudden decrease or loss of hearing has been reported in a few number of postmarketing and clinical trial cases with the use of PDE5 inhibitors, including VIAGRA. It has not been established whether these are related directly to the use of these medications or to other factors. If you experience these symptoms, stop taking VIAGRA and call your doctor.
