Start with the lowest dose (25mg) unless your doctor instructs otherwise. Common side effects include headache, flushing, nasal congestion, and indigestion. These usually are mild and temporary. If you experience them, consider drinking plenty of water and resting. They typically resolve within a few hours.
More Serious Side Effects
Rare but serious side effects include prolonged erection (priapism), sudden vision loss, and hearing loss. Seek immediate medical attention if you experience any of these. Priapism requires immediate treatment to prevent permanent damage. Vision or hearing changes need prompt evaluation by an ophthalmologist or audiologist.
Dosage Adjustments
Your doctor might adjust your dose based on your response and any side effects. If 25mg is ineffective, they may increase it to 50mg or 100mg. However, increasing the dose doesn’t always improve effectiveness and increases the risk of side effects. Conversely, if side effects are bothersome, a lower dose may be prescribed. Always follow your doctor’s instructions carefully. Never exceed the recommended dose without consulting a healthcare professional. They can help determine the optimal dosage for your individual needs.
Interactions
Important Note: Viagra can interact with other medications, including nitrates. Always inform your doctor about all medications you are taking, including over-the-counter drugs and supplements. This prevents dangerous interactions and helps ensure your safety.
