What is a potential side effect of SSRIs?

Selective serotonin reuptake inhibitors (SSRIs) are a commonly prescribed class of antidepressants that primarily work by increasing the levels of serotonin in the brain. Bruxism, or teeth grinding, is recognized as a potential side effect of SSRIs. This occurrence may stem from an increase in serotonergic activity in the brain, which can lead to muscle tension and involuntary movements. Since bruxism is related to muscle control, it can manifest in individuals taking SSRIs as compulsive grinding of teeth during sleep or even while awake.

The other side effects listed, while associated with different types of medications or conditions, are not commonly linked to SSRIs. For example, psychosis may occur in certain psychiatric disorders but not typically as a direct side effect of SSRIs. Hypertensive crisis is more associated with monoamine oxidase inhibitors and certain interactions with foods or drugs, while respiratory depression is often tied to opioid use or sedative medications rather than SSRIs. Therefore, bruxism aligns with the known side effects of SSRIs, making it the correct choice in this context.
