When should oral glucose not be administered?

Oral glucose should not be administered if the patient is unresponsive because they may have an impaired gag reflex or reduced ability to swallow safely. Administering glucose in such a state raises the risk of choking or aspiration, which can lead to serious complications or further harm. In emergency situations, ensuring that the airway is protected and that the patient can safely consume oral substances is crucial. Therefore, when a patient is unresponsive, alternative methods for glucose administration, such as intravenous administration, should be considered instead.

In contrast, conscious patients who are able to swallow can safely take oral glucose, even after eating or in cases of mild hypoglycemia, making response and safety key factors in determining whether to administer oral glucose.
