Which of the following is a potential side effect of NSAIDs?

Drowsiness can occur as a side effect of nonsteroidal anti-inflammatory drugs (NSAIDs), although it's not as common as other gastrointestinal or renal side effects. NSAIDs primarily work by inhibiting enzymes involved in the production of prostaglandins, which are involved in inflammation and pain. While the primary effects of NSAIDs are to alleviate pain and reduce inflammation, they can also affect the central nervous system in some patients, leading to side effects like drowsiness or dizziness, particularly when higher doses are taken or when combined with other central nervous system depressants.

The other options do not commonly relate to NSAID use. Excessive sweating is generally not associated with NSAIDs, and while numbness may occur in rare cases or due to an allergic reaction, it is not a typical side effect. Joint stiffness is more an indication of the condition being treated rather than a direct side effect of NSAIDs. Understanding these nuances helps to clarify the potential risks and effects of medications like NSAIDs.
