Always follow your doctor’s instructions precisely. Take tadalafil exactly as prescribed, typically one 20mg tablet as needed, at least 30 minutes before sexual activity. Do not exceed the recommended dosage. Alcohol consumption can interact negatively, potentially intensifying side effects. Grapefruit juice should also be avoided, as it can increase tadalafil levels in your blood.
Common Side Effects
Tadalafil can cause headaches, flushing, nasal congestion, and indigestion. These are usually mild and temporary. Muscle aches, back pain, and visual disturbances (such as changes in color vision or blurred vision) are also possibilities. These side effects generally resolve on their own. If any persist or worsen, consult your healthcare provider immediately. Serious side effects, while rare, include sudden vision loss or hearing loss, prolonged erection (priapism), and heart attack. Seek immediate medical attention if you experience any of these.
Serious Side Effects and Precautions
Priapism requires emergency medical care. Tadalafil is not suitable for individuals with certain heart conditions, low blood pressure, severe liver or kidney problems, or those who have experienced a recent stroke or heart attack. Individuals taking nitrates or alpha-blockers should inform their doctor before starting tadalafil, as a dangerous interaction can occur. Inform your doctor about all medications you are currently taking, including over-the-counter drugs and supplements, to prevent potential drug interactions. If you experience a sudden decrease or loss of vision, stop taking tadalafil and seek immediate medical attention.
