Drug Interaction Checker

Although an interaction is possible, Ethanol (alchohol) and Antihypertensive Agents (drugs used to reduce high blood pressure) may be used together. Ethanol or alchohol-containing beverages may increase the effects of Antihypertensive Agents on your blood pressure. If the blood pressure drops too low while taking Ethanol and Antihypertensive Agents, you may become dizzy or feel faint. To limit this interaction, avoid alcohol-containing beverages while taking medicines to lower your blood pressure. Do not stand or sit up too quickly. Contact your prescriber if you have dizziness which does not go away.

Grapefruit juice may increase blood concentrations of Alfuzosin by reducing Alfuzosin metabolism in the body. Too much Alfuzosin in the blood can lower the blood pressure. If the blood pressure drops too low, you may become dizzy or feel faint. To limit this interaction, it is probably best not to greatly change your intake of grapefruit or grapefruit juice while taking Alfuzosin. Contact your prescriber if you have dizziness which does not go away.
