Days: The half life of Haldol (haloperidol) is around 24 hours and after 5 half-lives the drug should be 99% out of your system. That means about 5 days, maybe a week at most.
Dr. Austina Cho
Psychiatry 26 years experience
7.5 days to 6 months: The half-life of Haldol (haloperidol) can vary from 1.5 days to more than 30 days, especially in those taking Haldol (haloperidol) decanoate, the long acting injectable form, once a month. It takes 4-5 half-lives to remove 94-97% of the drug concentration from the bloodstream. Therefore, it may take 7 1/2 days to 5 months or longer to remove it from the system.

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.

About a day: Haldol (haloperidol) doesn't persist in the body, it's gone after about a day. However, its effect may linger for a few days longer. This is true of many psychiatric drugs: their effects last longer than they are literally "in your system".
