Always inform your doctor about all medications you are taking, including over-the-counter drugs, supplements, and herbal remedies. This includes nitrates, which are often used to treat chest pain (angina). Combining Cialis daily 2.5 mg with nitrates can cause a dangerous drop in blood pressure.
Alpha-blockers, frequently prescribed for high blood pressure or enlarged prostate, can also interact with Cialis. Your doctor may adjust your dosage to minimize potential side effects like dizziness or fainting.
Certain antifungal medications (like ketoconazole or itraconazole) and HIV protease inhibitors can increase Cialis levels in your body, potentially leading to heightened side effects. Your physician might suggest a lower Cialis dose or an alternative treatment.
If you’re taking medications to treat high blood pressure, your doctor will carefully monitor your blood pressure after starting Cialis. Adjustments to your blood pressure medication may be necessary.
