Exceeding the recommended Viagra dosage significantly increases the risk of adverse effects. Common side effects, even at the prescribed dose, like headache, flushing, and nasal congestion, become more intense and frequent. You might experience a more pronounced drop in blood pressure, potentially leading to dizziness or fainting.
Cardiovascular Risks
Higher doses place a greater strain on your heart. This can manifest as chest pain (angina), irregular heartbeat (arrhythmia), or even a heart attack, particularly in individuals with pre-existing cardiovascular conditions. These risks are amplified by the simultaneous use of nitrates, which are commonly prescribed for heart conditions. Never combine Viagra with nitrates without explicit medical guidance.
Vision and Hearing Problems
Increased doses can cause temporary vision changes, such as blurred vision, increased light sensitivity, or even blue-tinged vision. In rare cases, hearing loss or ringing in the ears (tinnitus) may occur. These effects usually resolve once the drug is stopped, but immediate medical attention is advised if they persist.
Other Potential Complications
Prolonged erections (priapism) are a serious concern, requiring immediate medical intervention to prevent permanent damage. Severe back pain, muscle aches, and nausea also occur with increased frequency and severity at higher doses. Always prioritize your health and adhere to your doctor’s prescribed dosage.
