What is a common side effect associated with SNRI anti-depressants?

The correct answer, mydriasis, refers to the dilation of the pupils, which is a common side effect associated with serotonin-norepinephrine reuptake inhibitors (SNRIs). These medications affect the levels of neurotransmitters in the brain, leading not only to improvements in mood but also influencing ocular function through their anticholinergic effects, which can result in pupil dilation. This reaction is often due to the blockade of the parasympathetic nervous system.

It’s important to recognize that mydriasis can be significant for patients, particularly those with preexisting conditions affecting vision or those needing to drive. Understanding the side effects of SNRIs helps in managing patient expectations and monitoring for potential ocular complications.

The other options present eye-related symptoms but do not correspond to common side effects of SNRIs. Miosis, or constricted pupils, is more typically seen with certain opioid medications or specific types of medications affecting the parasympathetic nervous system. Blurred vision can occur with various medications, but it is not specifically associated with SNRIs. Dry eyes may be a side effect of many antidepressants, particularly those with anticholinergic properties, but in the case of SNRIs specifically, mydri
