Always inform your doctor about all medications you are taking, including over-the-counter drugs, herbal supplements, and recreational drugs. This includes nitrates, commonly found in medications for chest pain (angina). Combining Cialis with nitrates can cause a dangerous drop in blood pressure.
Alpha-blockers, used to treat high blood pressure and enlarged prostate, can also interact with Cialis, potentially leading to significantly low blood pressure. Your doctor may need to adjust your dosages or choose alternative medications.
Certain antifungals, such as ketoconazole and itraconazole, can increase Cialis levels in your blood, potentially intensifying side effects. Your doctor might recommend a lower Cialis dose or a different antifungal.
Drugs affecting liver enzymes, such as rifampin and erythromycin, can alter Cialis metabolism, impacting its effectiveness. Dosage adjustments may be necessary.
Grapefruit juice inhibits the enzymes that break down Cialis, resulting in higher blood levels and increased risk of side effects. Avoid grapefruit juice while taking Cialis.
