Other important side effects are:
- weight gain,

Haldol may cause a condition called "orthostatic hypotension" during the early phase of treatment (first week or two). Orthostatic hypotension causes patients to become dizzy upon arising from a lying or sitting position because of a drop in blood pressure.
Haldol also may cause abnormal heart beats, sudden death, seizures, decreases in red and white blood cells, and withdrawal symptoms.
What is the dosage for Haldol (haloperidol)?
- The recommended oral dose for schizophrenia is 0.5-5 mg two or three times daily up to a maximum dose of 30 mg daily. The lactate solution dose is 2-5 mg every 4-8 hours as needed by intramuscular injection. The lactate solution may also be administered by intravenous injection at 1-2 mg every 2-4 hours and titrated to effect. The maximum single injection dose is 50 mg and the maximum daily dose is 500 mg daily. The dose for the decanoate solution is 10-20 times the daily oral dose once monthly by intramuscular injection. The decanoate solution should not be administered intravenously.
