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

Verapamil Hydrochloride is a medication that is often prescribed as an antihypertensive and antianginal agent. A crucial counseling point is that patients should not crush or chew extended-release formulations. This is because the extended-release tablets are designed to release the medication gradually over time, maintaining stable drug levels in the bloodstream. If these tablets are crushed or chewed, instead of allowing for a slow release, the entire dose could be released at once, increasing the risk for side effects and potentially leading to dangerous drops in blood pressure or other adverse reactions.

In contrast, the other options are less pertinent to the safe and effective use of the medication. Taking the medication on an empty stomach may not be necessary for all patients. Doubling doses if missed can lead to toxicity and is generally advised against in most medication regimens. Lastly, while some medications may have flexibility with beverage compatibility, the specific recommendations for verapamil focus more on dosage form and administration, rather than beverage choice. Therefore, understanding the importance of not altering the formulation helps in preventing serious complications associated with improper medication administration.
