Which medication is associated with causing side effects such as mydriasis and dry eye?

The correct answer is associated with ADHD medications, as these drugs, particularly stimulants like amphetamines and methylphenidate, can lead to side effects like mydriasis (dilation of the pupils) and dry eye. Stimulants increase norepinephrine and dopamine levels in the brain, which can lead to various sympathetic nervous system effects, including pupil dilation. Additionally, these medications can decrease lacrimal gland function, leading to reduced tear production and thus dry eye symptoms.

In the context of the other options, antihistamines can also cause dry eye and mydriasis due to their anticholinergic effects, but ADHD medications are more prominently linked with these side effects due to their pharmacodynamic profiles. Beta-blockers primarily address cardiovascular conditions and do not typically cause these specific ocular symptoms. Corticosteroids may cause a variety of side effects, but they are not primarily associated with mydriasis and dry eye to the same extent as ADHD medications.
