Taking 800mg of Viagra significantly exceeds the recommended dosage. This carries substantial health risks. A typical prescription starts at 50mg, with adjustments based on individual response and tolerance. Doubling or quadrupling that dose dramatically increases the chance of adverse effects.
Cardiovascular problems are a major concern. Viagra affects blood flow, and a high dose can severely strain the heart, leading to chest pain, irregular heartbeat, or even heart attack, particularly in individuals with pre-existing heart conditions.
Vision problems are another risk. These can range from temporary blurred vision to more serious issues like non-arteritic anterior ischemic optic neuropathy (NAION), a condition causing vision loss. The higher the dose, the greater this risk.
Priapism, a prolonged and painful erection lasting more than four hours, is a serious complication. This requires immediate medical attention to prevent permanent damage.
High doses may also cause severe headaches, flushing, nasal congestion, and dizziness. These side effects, although generally less serious than cardiovascular or vision problems, can still significantly impair daily functioning.
Never exceed the prescribed dosage. Always consult your doctor before adjusting your medication or taking more than recommended. They can assess your health and determine the appropriate dose to minimize risk and maximize effectiveness.
Consider consulting a medical professional if you experience any concerning side effects after taking Viagra, regardless of the dosage. Early intervention can significantly reduce the severity of potential complications.
