Always inform your doctor about all medications you’re taking, including over-the-counter drugs, supplements, and herbal remedies. Tadalafil can interact negatively with certain medications, potentially leading to adverse effects. Specifically, combining Tadalafil with nitrates (used to treat chest pain) can cause a dangerous drop in blood pressure.
Alpha-Blockers and Tadalafil
Using Tadalafil with alpha-blockers (treating high blood pressure or enlarged prostate) may significantly lower blood pressure, potentially causing dizziness or fainting. Your doctor may need to adjust your dosages carefully.
Other Notable Interactions
Certain antifungals (like ketoconazole and itraconazole), HIV protease inhibitors (like ritonavir and indinavir), and macrolide antibiotics (like erythromycin and clarithromycin) can increase Tadalafil levels in your blood, potentially intensifying its effects and side effects. Discuss these interactions with your physician before combining them.
Grapefruit juice also interacts with Tadalafil, increasing its concentration in the blood. Avoid grapefruit juice while taking this medication.
