Tadalafil interactions:

Both tadalafil and alpha-blockers can lower blood pressure. When combined, this can lead to an excessive drop in blood pressure, resulting in dizziness, lightheadedness, fainting, or even a heart attack. Tadalafil interactions may enhance the blood pressure-lowering effects of other antihypertensive medications, which can increase the risk of low blood pressure. Inform your healthcare provider about any blood pressure medications you’re using so they can adjust doses if necessary. Always inform your healthcare provider about all the medications you’re currently taking, including over-the-counter drugs, herbal supplements, and vitamins, to avoid harmful interactions.
