Cialis, while generally safe and effective, can cause side effects. These vary in severity and frequency.
Common side effects include:
- Headache Facial flushing Nasal congestion Muscle aches Back pain Indigestion
Less common, but more serious, side effects require immediate medical attention:
- Sudden vision loss Sudden hearing loss Prolonged erection (priapism) Chest pain
Drug interactions are also a concern. Cialis should not be taken with nitrates (used to treat angina) due to the risk of dangerously low blood pressure. Additionally, interactions may occur with:
- Alpha-blockers (used to treat high blood pressure and benign prostatic hyperplasia) Certain antifungals HIV protease inhibitors Some antibiotics
Always inform your doctor about all medications, supplements, and herbal remedies you are taking before starting Cialis. This helps prevent potential interactions and ensures your safety.
