Which of the following is a key patient counseling point for Diltiazem Hydrochloride?

Diltiazem Hydrochloride is a calcium channel blocker used primarily for managing hypertension and certain types of angina. A crucial counseling point for patients taking this medication is the recommendation to avoid alcohol. Alcohol can amplify the blood pressure-lowering effects of Diltiazem, increasing the risk of side effects such as dizziness, lightheadedness, and a rapid heartbeat. Moreover, alcohol can be detrimental to overall cardiovascular health, making it particularly important for patients to limit or avoid it while on this treatment.

The other choices present counseling points that do not align with best practices. Administering the drug with hot food is not a standard recommendation and does not significantly affect its absorption. Advising patients to take the medication only on an empty stomach is incorrect, as Diltiazem can be taken with or without food, depending on the specific product formulation. Finally, it is important for patients to understand that medications like Diltiazem should not be discontinued abruptly even if they start to feel better without consulting their healthcare provider, as this could lead to an exacerbation of their condition.
