• Do not drink alcohol or use medicines that may cause drowsiness (eg, sleep aids, muscle relaxers) while you are using Reglan without first checking with your doctor; it may add to their effects. Ask your pharmacist if you have questions about which medicines may cause drowsiness.

• Some patients who take Reglan 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 Reglan 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 Reglan.
• Patients who take Reglan may be at increased risk for new or worsening mental or mood changes (eg, depression) or suicidal thoughts or actions. Watch patients who take Reglan closely.

Contact the doctor right away if any signs of suicidal thoughts or actions occur.

• Lab tests, including liver and kidney function tests, may be performed while you use Reglan. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
• Use Reglan with caution in the elderly; they may be more sensitive to its effects, especially drowsiness, confusion, and uncontrolled muscle movements, including tardive dyskinesia.
• Reglan should be used with extreme caution in children; safety and effectiveness in children have not been confirmed. The risk of developing uncontrolled muscle movements may be greater in children.
• Pregnancy and breast-feeding: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using Reglan while you are pregnant. Reglan is found in breast milk. If you are or will be breast-feeding while you use Reglan, check with your doctor. Discuss any possible risks to your baby.
