Always follow your doctor’s prescribed dosage. Typical starting doses range from 5mg to 20mg, taken as needed.
Common side effects include headache, flushing, nasal congestion, and indigestion. These are usually mild and temporary.
- Headache: Drink plenty of water and consider over-the-counter pain relievers like ibuprofen or acetaminophen. Flushing: Wear loose clothing and stay hydrated. Nasal Congestion: Use saline nasal spray to help clear nasal passages. Indigestion: Take the medication with food to minimize stomach upset.
More serious side effects, though rare, include vision changes (blurred vision, sudden vision loss), hearing loss, prolonged erection (priapism), and chest pain. Seek immediate medical attention if you experience any of these.
Dosage adjustments depend on individual responses and should be discussed with a healthcare professional. Never increase your dosage without consulting a doctor.
Adjustments: Your doctor may recommend a lower or higher dose based on your response and any side effects. Frequency: Do not exceed the recommended frequency. Taking more than the prescribed amount will not enhance results and may increase the risk of side effects. Interaction with other medications: Inform your doctor about all medications you are taking, including herbal remedies, to avoid potential interactions.
Proper hydration is crucial for minimizing side effects. Drink plenty of water throughout the day.
