3. Due to increased risk for drowsiness, a patient taking zolpidem should avoid OTC products containing:
Answer: C
Patients taking zolpidem should avoid OTC products containing diphenhydramine.
Diphenhydramine is an antihistamine that can cause sedation and drowsiness, which may exacerbate the effects of zolpidem, increasing the risk of excessive drowsiness and impaired function.
A) acetaminophen.
Acetaminophen is a pain reliever and fever reducer that does not have sedative properties. Therefore, it does not pose an increased risk of drowsiness when taken with zolpidem and is generally considered safe for patients taking this medication.
B) naproxen.
Naproxen is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve pain and inflammation. Similar to acetaminophen, it does not have sedative effects and does not significantly increase the risk of drowsiness when taken in conjunction with zolpidem.
C) diphenhydramine.
Diphenhydramine is an antihistamine known for its sedative effects. It can enhance the drowsiness caused by zolpidem, making it dangerous for patients who need to maintain alertness or who are at risk of excessive sedation.
D) guaifenesin.
Guaifenesin is an expectorant used to relieve chest congestion and does not have sedative properties. It is safe to use in conjunction with zolpidem, as it does not contribute to drowsiness.
Conclusion
The correct answer is C) diphenhydramine, as it poses a significant risk of increased drowsiness when combined with zolpidem. In contrast, the other options—acetaminophen, naproxen, and guaifenesin—do not have sedative effects and are considered safe to use with zolpidem. Understanding these interactions is crucial for patient safety and effective medication management.
