Always inform your doctor about all medications you are currently taking, including over-the-counter drugs, supplements, and herbal remedies. This includes nitrates used to treat chest pain (angina). Combining tadalafil with nitrates can cause a dangerous drop in blood pressure.
Specific Medications to Note
Certain antifungal medications (like ketoconazole and itraconazole) and HIV protease inhibitors (like ritonavir) can increase tadalafil levels in your blood, potentially leading to side effects. Alpha-blockers, often prescribed for high blood pressure or enlarged prostate, can interact with tadalafil, causing dizziness or fainting. Discuss these interactions with your physician before using tadalafil.
Grapefruit juice can also affect how your body processes tadalafil; avoid consuming it while taking this medication.
This information is not exhaustive. Consult your doctor or pharmacist for personalized advice on potential drug interactions before starting any new medication while taking tadalafil 40mg.
