Tadalafil, like all medications, can cause side effects. Common ones include headache, flushing, nasal congestion, and indigestion. These usually are mild and temporary. Less common, but more serious, side effects include vision changes (blurred vision, changes in color vision), hearing loss, and prolonged erection (priapism). Seek immediate medical attention if you experience a prolonged erection lasting more than four hours or sudden vision or hearing loss.
Interactions with Other Medications
Tadalafil interacts with certain medications, particularly nitrates used to treat angina. Combining them can cause a dangerous drop in blood pressure. You should inform your doctor about all medications you’re currently taking, including over-the-counter drugs, herbal remedies, and supplements. This includes medications for high blood pressure, heart conditions, or HIV/AIDS. Alpha-blockers, often prescribed for high blood pressure or enlarged prostate, can also interact with Tadalafil, potentially causing dizziness or fainting. Your doctor will help determine if Tadalafil is safe for you given your specific health conditions and medication regimen. Always follow your doctor’s instructions regarding dosage and potential interactions.
Specific Medications to Discuss with Your Doctor
Before starting Tadalafil, it is crucial to discuss your use of medications like nitrates (e. g., nitroglycerin), alpha-blockers (e. g., terazosin, tamsulosin), certain antifungals (e. g., ketoconazole, itraconazole), HIV protease inhibitors (e. g., ritonavir, indinavir), and other medications that may affect the liver or kidneys. These medications can influence the metabolism and effectiveness of Tadalafil, potentially increasing the risk of side effects.
