Start with the lowest effective dose (25 mg) to minimize potential side effects. Common side effects include headache, flushing, nasal congestion, and visual disturbances. These usually are mild and transient.
If side effects are bothersome, consider reducing the dose to 25 mg or trying the medication on alternate days. Always consult your doctor before making any dosage adjustments.
Severity and Frequency
The frequency and intensity of side effects vary greatly among individuals. Some men experience no side effects at all, while others might experience more pronounced symptoms.
| Headache | Common | Reduce dose or try over-the-counter pain relief (consult your doctor first). |
| Flushing | Common | May subside with continued use. If severe, reduce dose. |
| Nasal Congestion | Common | May resolve spontaneously. Consult your doctor if persistent. |
| Visual Disturbances (blurred vision, changes in color perception) | Less common | Reduce dose or discontinue use. Consult your doctor immediately. |
| Dizziness | Less common | Avoid activities requiring alertness. Reduce dose or consult your doctor. |
Dosage Modification Based on Individual Factors
Your doctor might adjust your dosage based on factors like your age, overall health, and other medications you’re taking. Liver or kidney problems can also influence the appropriate dosage. Open communication with your doctor is crucial for safe and effective treatment.
Serious Side Effects
Seek immediate medical attention if you experience a sudden decrease or loss of vision, prolonged and painful erection (priapism), or chest pain. These are rare but potentially serious side effects.
