An older adult client has been taking zolpidem as a sleep aid for the past 2 months. On admission to the assisted living facility, it is determined that the drug is no longer needed. What guideline should be included in the nurse's care?

A. The client has a risk of hallucinations when the dosage is adjusted: Hallucinations are not a common withdrawal symptom of zolpidem, although confusion and abnormal thoughts may occur, especially with long-term use. This is not the primary concern during discontinuation. B. The drug needs to be withdrawn gradually: Zolpidem can cause dependence, especially in older adults. To avoid withdrawal symptoms such as anxiety, agitation, or rebound insomnia, gradual tapering rather than abrupt cessation is recommended. C. There is a risk of excessive sedation when the drug is discontinued: Discontinuation of zolpidem does not cause excessive sedation; instead, clients may experience insomnia or agitation. Excessive sedation is more likely with ongoing use or overdose, not withdrawal. D. Sundowning is common with withdrawal from this drug: Sundowning is associated with dementia and is not specifically caused by zolpidem withdrawal. Though older adults are more sensitive to CNS effects, sundowning is not a typical withdrawal concern for this medication.
