Can haloperidol affect my study?

Depends on condition: Haloperidol is used for psychosis. If you cannot study because you are hearing voices or your thoughts are so scattered that you can't stay on topic, this medication can help. Otherwise, if you are not suffering from schizophrenia, it will affect you negatively. People describe themselves as having "cotton brain" while on this medication.

Haloperidol: As stated earlier, by correcting psychotic symptoms the Haldol may help you with studying. However, if you had a side effect such as sedation, that might impede you from quality studying.
