Some medicines may interact with aripiprazole. Tell your health care provider if you are taking any other medicines, especially any of the following:
Anticholinergics (eg, benztropine, methscopolamine) because the risk of overheating may be increased
Benzodiazepines (eg, lorazepam), clarithromycin, fluoxetine, itraconazole, ketoconazole, paroxetine, or quinidine because they may increase the risk of aripiprazoles side effects

Important safety information
Aripiprazole may cause drowsiness, dizziness, or light-headedness. These effects may be worse if you take it with alcohol or certain medicines.
Use aripiprazole with caution. Do not drive or perform other possibly unsafe tasks until you know how you react to it.
Do not drink alcohol while you are using aripiprazole.
Check with your doctor before you use medicines that may cause drowsiness (eg, sleep aids, muscle relaxers) while you are using aripiprazole; it may add to their effects. Ask your pharmacist if you have questions about which medicines may cause drowsiness.
Aripiprazole may cause dizziness, light-headedness, or fainting; alcohol, hot weather, exercise, or fever may increase these effects.
To prevent them, sit up or stand slowly, especially in the morning. Sit or lie down at the first sign of any of these effects.
Do not take more than the recommended dose or use more often than prescribed without checking with your doctor.
NMS is a possibly fatal syndrome that can be caused by aripiprazole. Symptoms may include fever, stiff muscles, confusion, abnormal thinking, fast or irregular heartbeat, and sweating.
Some patients who take aripiprazole 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 aripiprazole 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 aripiprazole.
Older adults with dementia taking medicines like this one have had a higher number of strokes. Sometimes these strokes have been deadly. Aripiprazole is not approved to treat mental problems caused by dementia. Talk with your doctor.
Do not become overheated or dehydrated in hot weather or while you are being active; heatstroke may occur.
Aripiprazole may lower the ability of your body to fight infection. Avoid contact with people who have colds or infections. Tell your doctor if you notice signs of infection such as fever, sore throat, rash, or chills.
Aripiprazole may raise your blood sugar or increase your risk of developing diabetes. High blood sugar may make you feel confused, drowsy, or thirsty. It can also make you flush, breathe faster, or have a fruit-like breath odor. If these symptoms occur, tell your doctor right away.
Diabetes patients - Aripiprazole may affect your blood sugar. Check blood sugar levels closely. Ask your doctor before you change the dose of your diabetes medicine.
