• Sildenafil should be taken as directed, usually 30-60 minutes before sexual activity.
• Do not crush, chew, or break the tablet; swallow it whole with water.
• Taking it with a high-fat meal can delay the onset of action.

• Grapefruit can increase the level of sildenafil in your bloodstream.
• This raises the risk of side effects.
• Stick to the prescribed schedule and do not take extra doses.

The available formats in Canadian pharmacies include: Viagra® works by protecting specific molecules that allow smooth muscles to relax and increase blood flow. At a biological level, sildenafil is a selective inhibitor of the PDE5 enzyme. Under normal conditions, this enzyme breaks down a substance called cyclic guanosine monophosphate (cGMP). By blocking PDE5, Viagra® allows cGMP levels to remain elevated. This leads to the relaxation of smooth muscles in the walls of blood vessels, which facilitates increased blood flow to specific areas of the body. Usage involves oral administration according to strict timing and safety guidelines provided by a healthcare professional. Viagra® is taken orally, generally with or without food. Because its absorption can be delayed by high-fat meals, timing is an essential pharmaceutical consideration. It is typically administered as a single dose when needed, and it is strictly recommended that users do not exceed one dose within a 24-hour period. Dosage adjustments are made based on individual physiological responses and safety profiles. Proper storage ensures the chemical stability and shelf-life of the sildenafil citrate compound. Temperature: Store at room temperature between 15°C and 30°C. Environment: Keep the tablets in a dry place away from moisture (avoid bathroom cabinets). Safety: Ensure the medication is kept in its original packaging and out of reach of children. Users may experience common physiological shifts or rare, more serious reactions requiring immediate clinical attention. Abnormal vision (such as a blue color tinge or blurred vision) Priapism: A prolonged and potentially painful physiological reaction lasting over four hours. Sudden Vision Loss: Rare reports of decreased or loss of vision in one or both eyes. Sudden Hearing Decrease: Sudden decrease or loss of hearing, sometimes accompanied by dizziness. Health Canada emphasizes strict precautions regarding cardiovascular health and specific pre-existing medical conditions. Before using Viagra®, it is vital to have a cardiovascular screening. The medication can cause a temporary decrease in blood pressure. It is not recommended for individuals with severe heart or liver problems, or those who have recently had a stroke or heart attack.
