It is very important that your doctor check your progress at regular visits. This will allow your doctor to see if the medicine is working properly and to decide if you should continue to take it.
Do not take this medicine if you are also taking a monoamine oxidase (MAO) inhibitor such as isocarboxazid (Marplan®), phenelzine (Nardil®), selegiline (Eldepryl®), or tranylcypromine (Parnate®) within 14 days of each other. If you have questions, check with your doctor.
This medicine may cause some people to be agitated, irritable, or display other abnormal behaviors. It may also cause some people to have suicidal thoughts and tendencies or to become more depressed, especially if they have a condition called Huntington's disease. If you or your caregiver notice any of these side effects, tell your provider right away.
This medicine may cause a serious allergic reaction, including angioedema, which can be life-threatening and require immediate medical attention. Check with your doctor right away if you have large, hive-like swelling on your face, eyelids, lips, tongue, throat, hands, legs, feet, or genitals.
This medicine may cause some people to become sleepy or drowsy. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that requires you to be alert.
Contact your doctor right away if you have any changes to your heart rhythm. You might feel dizzy or faint, or you might have a fast, pounding, or uneven heartbeat. Make sure your doctor knows if you or anyone in your family has ever had a heart rhythm problem, including QT prolongation.
Check with your doctor right away if you have difficulty with breathing, a fast heartbeat, a high fever, high or low blood pressure, increased sweating, loss of bladder control, seizures, severe muscle stiffness, unusually pale skin, or tiredness. These could be symptoms of a serious condition called neuroleptic malignant syndrome (NMS).
This medicine may cause parkinsonism (a movement disorder). Check with your doctor right away if you have difficulty swallowing, loss of balance control, mask-like face, shuffling walk, slowed movements, slurred speech, stiffness of the arms and legs, tic-like or jerky movements of the head, face, mouth, and neck, or trembling and shaking of the fingers and hands.
