Possible food and drug interactions when taking tadalafil

The breakdown and elimination of tadalafil from the body may be decreased by erythromycin, ketoconazole (nizoral), itraconazole (sporanox), indinavir (crixivan) and ritonavir (norvir). therefore, these drugs may increase the concentration of tadalafil (tadalafil) in the blood. if these drugs are being used at the same time as tadalafil (tadalafil), the dose of tadalafil should be reduced in order to avoid side effects from high levels of tadalafil.

Tadalafil increases the heart rate and also exaggerates the blood pressure lowering effects of nitrates (e.g., nitroglycerin). in patients who take nitrates for chest pain (angina), tadalaafil could cause chest pain by increasing heart rate and lowering blood pressure. therefore, patients with angina should not use tadalafil.

Tadalafil also exaggerates the blood pressure lowering effects of some alpha-blocking drugs e.g., terazosin (hytrin). individuals who take these alpha-blockers should not use tadalafil (tadalafil).
