Always inform your doctor about all medications you are taking, including over-the-counter drugs, herbal remedies, and supplements, before starting Levitra 40 mg. This is crucial for safe use.
Nitrates: Combining Levitra with nitrates (found in medications for chest pain) can cause a dangerous drop in blood pressure. This combination is strictly contraindicated.
Alpha-blockers: Concurrent use with alpha-blockers (used to treat high blood pressure or enlarged prostate) may increase the risk of low blood pressure, especially when starting or increasing the dosage of either medication. Your doctor should carefully monitor your blood pressure.
CYP3A4 Inhibitors: Medications that inhibit the CYP3A4 enzyme (like ketoconazole, erythromycin, and some HIV medications) can increase Levitra’s levels in your blood, potentially leading to increased side effects. Dosage adjustments may be necessary.
CYP3A4 Inducers: Conversely, medications that induce CYP3A4 (like rifampin and St. John’s Wort) can decrease Levitra’s effectiveness. Your doctor might need to adjust your Levitra dosage or consider alternative treatment.
Alcohol: Excessive alcohol consumption can reduce Levitra’s effectiveness and increase the risk of side effects. Moderate alcohol intake is generally acceptable, but consult your physician for personalized advice.
This information is not exhaustive. Always consult your physician or pharmacist for a comprehensive assessment of potential drug interactions before taking Levitra 40 mg, especially if you have underlying health conditions.
