Consult your doctor before using Cialis, especially if you have heart problems, low blood pressure, or a history of stroke. They can help determine the appropriate dosage and monitor for potential issues.
Common side effects include headache, flushing, nasal congestion, and indigestion. These usually are mild and temporary. However, report any persistent or worsening symptoms to your doctor immediately.
Medication Interactions
Cialis interacts with certain medications, including nitrates (used to treat chest pain) and alpha-blockers (used to treat high blood pressure). Combining these can cause a dangerous drop in blood pressure. Inform your doctor about all medications, supplements, and herbal remedies you are taking.
Alcohol and Grapefruit Juice
Limit alcohol consumption while taking Cialis as it can intensify side effects. Similarly, avoid grapefruit juice, as it can interfere with the drug’s metabolism.
Serious Side Effects
Seek immediate medical attention if you experience sudden vision loss, prolonged erection (priapism), or chest pain. These are rare but serious side effects requiring prompt medical care.
