Revatio, like all medications, can cause side effects. Understanding their frequency and potential severity helps you make informed decisions with your doctor. Headaches are common, affecting approximately 10-20% of users. These are usually mild and resolve without intervention. However, if headaches are severe or persistent, contact your healthcare provider immediately.
Gastrointestinal Issues
Some individuals experience nausea, which usually manifests as a mild feeling of discomfort. This affects a smaller percentage of users than headaches, typically under 5%. More serious gastrointestinal issues, such as vomiting or diarrhea, are less frequent, occurring in less than 1% of cases. If you experience severe or persistent gastrointestinal problems, seek medical advice.
Other Potential Side Effects
Flushing, a sensation of warmth in your face, neck, and chest, can occur in around 5-10% of patients. It’s usually temporary and mild. Less common side effects include dizziness, nasal congestion, and back pain. The frequency of these is generally below 5%. Always report any concerning side effects to your doctor. Remember, this information is for general understanding and does not replace professional medical advice.
Severity and Management
Severity of side effects varies greatly between individuals. What might be mildly bothersome for one person could be significant for another. Management often involves simple adjustments, like taking Revatio with food to mitigate nausea. For more severe side effects, your doctor may suggest alternative treatment options or adjustments to your dosage.
