Studies have shown that older adults with dementia (a brain disorder that affects the ability to remember, think clearly, communicate, and perform daily activities and that may cause changes in mood and personality) who take antipsychotics (medications for mental illness) such as loxapine have an increased chance of death during treatment.
Loxapine is not approved by the Food and Drug Administration (FDA) for the treatment of behavior problems in older adults with dementia. Talk to the doctor who prescribed this medication if you, a family member, or someone you care for has dementia and is taking loxapine. For more information visit the FDA website: Web Site
Loxapine is used to treat the symptoms of schizophrenia (a mental illness that causes disturbed or unusual thinking, loss of interest in life, and strong or inappropriate emotions). Loxapine is in a group of medications called conventional antipsychotics. It works by decreasing abnormal excitement in the brain.
Loxapine comes as a capsule to take by mouth. It is usually taken two to four times a day. Try to take loxapine at around the same times every day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take loxapine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Your doctor will probably start you on a low dose of loxapine and increase your dose during the first 7 to 10 days of your treatment until your symptoms are controlled. Once your symptoms have been controlled for some time, your doctor may decrease your dose. Be sure to tell your doctor how you are feeling during your treatment with loxapine.
Loxapine may control your symptoms but will not cure your condition. It may take several weeks or longer for you to feel the full benefit of loxapine. Continue to take loxapine even if you feel well. Do not stop taking loxapine without talking to your doctor.
This medication may be prescribed for other uses. Ask your doctor or pharmacist for more information.
Before taking loxapine,
- tell your doctor and pharmacist if you are allergic to loxapine or any other medications.
- tell your doctor and pharmacist what prescription and nonprescription medications, vitamins, nutritional supplements, and herbal products you are taking or plan to take. Be sure to mention any of the following: antidepressants; antihistamines; atropine (in Motofen, in Lomotil, in Lonox); barbiturates such as pentobarbital (Nembutal), phenobarbital (Luminal), and secobarbital (Seconal); epinephrine (Epipen); ipratropium (Atrovent); lorazepam (Ativan); medications for anxiety, irritable bowel disease, mental illness, motion sickness, Parkinson's disease, seizures, ulcers, or urinary problems; narcotic medications for pain; sedatives; sleeping pills; and tranquilizers. Your doctor may need to change the doses of your medications or monitor you carefully for side effects.
- tell your doctor if you have or have ever had seizures, difficulty urinating, glaucoma (condition in which increased pressure in the eye can lead to gradual loss of vision), breast cancer, or heart disease. Also tell your doctor if you have ever had to stop taking any medication for mental illness due to severe side effects.
- tell your doctor if you are pregnant, especially if you are in the last few months of your pregnancy, or if you plan to become pregnant or are breast-feeding. If you become pregnant while taking loxapine, call your doctor. Loxapine may cause problems in newborns following delivery if it is taken during the last months of pregnancy.
- if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking loxapine.
- you should know that this medication may make you drowsy and may affect your thinking and movements. Do not drive a car or operate machinery until you know how this medication affects you.
- ask your doctor about the safe use of alcohol during your treatment with loxapine. Alcohol can make the side effects of loxapine worse.
- you should know that loxapine may cause dizziness, fainting, and lightheadedness, especially when you get up from a lying position. To avoid this problem, get out of bed slowly, resting your feet on the floor for a few minutes before standing up.
