Abilify is not for use in psychotic conditions that are related to dementia. Abilify may cause heart failure, sudden death, or pneumonia in older adults with dementia-related conditions. Stop using Abilify and call your doctor at once if you have the following symptoms: fever with stiff muscles and rapid heart rate; uncontrolled muscle movements; symptoms that come on suddenly such as numbness or weakness, severe headache, and problems with vision, speech, or balance. Abilify can cause side effects that may impair your thinking or reactions. Be careful if you drive or do anything that requires you to be awake and alert. Avoid drinking alcohol, which can increase some of the side effects of Abilify. Before you take aripiprazole, tell your doctor if you regularly use other medicines that make you sleepy (such as cold or allergy medicine, narcotic pain medicine, sleeping pills, muscle relaxers, and medicine for seizures, depression, or anxiety). They can add to sleepiness caused by Abilify. Avoid becoming overheated or dehydrated. Drink plenty of fluids, especially in hot weather and during exercise. It is easier to become dangerously overheated and dehydrated while you are taking Abilify.
