Which of the following is NOT a side effect of opioid medications?

Opioid medications are well-known for producing a range of side effects due to their impact on the central nervous system. Among these effects, drowsiness, constipation, and respiratory depression are commonly associated with opioid use. Drowsiness results from the sedative properties of opioids, which can impair alertness and cognitive functioning. Constipation is a frequent side effect due to opioids’ effects on the gut, disrupting normal bowel motility. Respiratory depression is a serious side effect where the respiratory rate is reduced, posing significant risks, particularly in cases of overdose.

In contrast, increased energy is not a side effect linked to opioid use. Instead of stimulating energy levels, opioids generally have a calming or sedating effect on the body. This characteristic distinguishes them from stimulants, which are associated with increased energy and alertness. Therefore, identifying increased energy as not being a side effect of opioids reflects an understanding of the typical effects and risks associated with opioid medications.
