Always inform your doctor about all medications you take, including over-the-counter drugs and supplements, before starting Cialis. This helps prevent potentially harmful interactions.
Common side effects include headache, flushing, nasal congestion, and indigestion. These are usually mild and temporary.
- Headache: Often resolves on its own. Consider over-the-counter pain relievers if needed. Flushing: Feeling of warmth or redness in your face. This usually subsides quickly. Nasal Congestion: A stuffy nose. Saline nasal spray may provide relief. Indigestion: Avoid large meals and fatty foods before taking Cialis.
Less common, but more serious, side effects require immediate medical attention:
- Sudden vision loss Prolonged erection (priapism) Chest pain Irregular heartbeat
Specific drug interactions can occur. For example, combining Cialis with nitrates can cause a dangerous drop in blood pressure.
Nitrates: Used to treat angina (chest pain). Avoid using these together. Alpha-blockers: Prescribed for high blood pressure or enlarged prostate. Your doctor may adjust your dosage. Some antifungals: Check with your doctor before combining with Cialis.
