Always follow your doctor’s instructions regarding Levitra dosage. The typical starting dose is 10 mg, taken as needed, approximately 60 minutes before sexual activity. Your doctor may adjust this based on your response and individual needs. Higher doses (up to 20 mg) may be prescribed, but never exceed the recommended maximum without consulting your physician.
Understanding Dosage Adjustments
Several factors influence Levitra dosage. Liver or kidney impairment may necessitate a lower dose. Certain medications can also affect Levitra’s metabolism, requiring dose modifications. Always inform your doctor about all medications you’re taking, including over-the-counter drugs and supplements. Grapefruit juice can significantly increase Levitra’s concentration in the blood; avoid consuming it while using this medication.
Medication Interactions
Important: Levitra can interact negatively with nitrates (used to treat chest pain) and alpha-blockers (used to treat high blood pressure). Combining them can cause a dangerous drop in blood pressure. Be sure to disclose any heart conditions or blood pressure medication you are using to your doctor before starting Levitra. Other medications that may interact with Levitra include certain antifungals, antibiotics, and HIV protease inhibitors. Always discuss potential interactions with your physician before starting any new medication.
Side Effects
Common side effects include headache, flushing, nasal congestion, and indigestion. More serious, though rare, side effects include vision changes, hearing loss, and prolonged erection (priapism). Seek immediate medical attention if you experience any of these serious side effects. This information is not a substitute for professional medical advice. Consult your physician for personalized guidance and to address any concerns you may have.
