💡💊 *Haloperidol and Weight Gain* Haloperidol, a first-generation (typical) antipsychotic, is generally associated with less weight gain compared to many second-generation (atypical) antipsychotics like olanzapine or clozapine. However, weight gain can still occur in some individuals, particularly with long-term use. ☀️A systematic review of antipsychotics showed that weight gain with haloperidol is relatively modest compared to atypical antipsychotics. ☀️Studies report an average weight gain of 1-3 kg (2.2–6.6 lbs) over the first year of treatment.
