Loxapine
Why this is used
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.
How to take it
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.
