Always consult your doctor before starting Cialis, especially if you have underlying health conditions. Common side effects include headache, flushing, nasal congestion, and indigestion. These are usually mild and temporary.
More serious, though less common, side effects include vision changes (blurred vision, sudden vision loss), hearing loss, prolonged erection (priapism), and chest pain. Seek immediate medical attention if you experience any of these.
Specific Drug Interactions
Cialis interacts with certain medications. Combining it with nitrates can cause a dangerous drop in blood pressure. This is a serious concern; avoid concurrent use.
Similarly, alpha-blockers, often prescribed for high blood pressure or enlarged prostate, can increase the risk of low blood pressure when taken with Cialis. Your doctor should carefully monitor your blood pressure if you’re on both medications.
Also, be aware that Cialis can interact with antifungal medications, such as ketoconazole and itraconazole. These can increase Cialis’s concentration in the body, potentially enhancing side effects. Discuss these interactions with your physician.
Other Considerations
Grapefruit juice can affect Cialis metabolism, leading to higher levels in your bloodstream. Limit or avoid grapefruit juice while taking Cialis.
