A licensed health care provider has recently prescribed a patient Alendronate after a DEXA scan. The LPN knows that when the patient takes this medication they need to:

A. Lay down after taking to prevent orthostatic hypotension: Lying down after taking alendronate increases the risk of esophageal irritation and ulceration. The medication’s proper administration requires an upright position, this action is contraindicated. B. Take this medication with milk to improve calcium absorption: Alendronate should be taken on an empty stomach with plain water because calcium and other minerals can bind to the drug, significantly reducing its absorption and therapeutic effectiveness in treating osteoporosis. C. Sit up right for 30 minutes to prevent esophageal erosion: Remaining upright for at least 30 minutes after ingestion helps prevent esophageal irritation and ulceration, which are common adverse effects of bisphosphonates. Adequate time also ensures proper drug transit to the stomach for optimal absorption. D. Take this medication with food to prevent GI upset: Food significantly decreases alendronate absorption. The medication must be taken on an empty stomach to achieve its intended effect, and delaying food intake for at least 30 minutes helps balance efficacy with gastrointestinal safety.
