Precautions
It is very important that your doctor check your progress at regular visits to make sure that this medicine is working properly.
This medicine will add to the effects of alcohol and other CNS depressants (medicines that make you drowsy or less alert). Some examples of CNS depressants are antihistamines or medicine for hay fever or colds; sedatives, tranquilizers, or sleeping medicine; prescription pain medicine or narcotics; medicine for seizures or barbiturates; muscle relaxants; or anesthetics, including some dental anesthetics. Check with your doctor before taking any of the above while you are using this medicine.
This medicine may cause some people to become dizzy, lightheaded, drowsy, or less alert than they are normally. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy or not alert.
This medicine may cause tardive dyskinesia (a movement disorder). Check with your doctor right away if you have any of the following symptoms while taking this medicine: lip smacking or puckering, puffing of the cheeks, rapid or worm-like movements of the tongue, uncontrolled chewing movements, or uncontrolled movements of the arms and legs.
Tell your doctor right away if you have the following symptoms while you are using this medicine: inability to move the eyes; increased blinking or spasms of the eyelid; sticking out of tongue; trouble in breathing, speaking, or swallowing; uncontrolled twisting movements of the neck, trunk, arms, or legs; unusual facial expressions; or weakness of the arms and legs.
Stop taking this medicine and check with your doctor right away if you have any of the following symptoms while using this medicine: convulsions (seizures); difficulty with breathing; a fast heartbeat; a high fever; high or low blood pressure; increased sweating; loss of bladder control; severe muscle stiffness; unusually pale skin; or tiredness. These could be symptoms of a serious condition called neuroleptic malignant syndrome (NMS).
Do not stop using this medicine suddenly without checking first with your doctor. You may need to slowly decrease your dose before stopping it completely to prevent withdrawal symptoms such as dizziness, headaches, or nervousness.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
