Can haldol cause pinpoint pupil

Yes, Haldol (haloperidol) can cause pinpoint pupils as a potential side effect. This phenomenon is often linked to the drug's effect on neurotransmitter systems, particularly its action as a dopamine antagonist. While pinpoint pupils are more commonly associated with opioid use, they can also occur with certain antipsychotics like Haldol. If you experience this side effect, it's important to consult your healthcare provider.
