- Do not drink alcohol or use medicines that may cause drowsiness (eg, sleep aids, muscle relaxers) while you are using Haldol; it may add to their effects. Ask your pharmacist if you have questions about which medicines may cause drowsiness.
- Do NOT use more than the recommended dose without checking with your doctor.

- Some patients who take Haldol may develop muscle movements that they cannot control. This is more likely to happen in elderly patients, especially women. The chance that this will happen or that it will become permanent is greater in those who take Haldol in higher doses or for a long time. Muscle problems may also occur after short-term treatment with low doses. Tell your doctor at once if you have muscle problems with your arms; legs; or your tongue, face, mouth, or jaw (eg, tongue sticking out, puffing of cheeks, mouth puckering, chewing movements) while taking Haldol.

- Lab tests, including complete blood cell counts, may be performed while you use Haldol. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lap appointments.
- Use Haldol with caution in the elderly; they may be more sensitive to its effects, especially uncontrolled muscle movements.
