What is Loxapine?
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 should this medicine be used?
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.

What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA’s Safe Disposal of Medicines website (http://goo.gl/c4Rm4p) for more information if you do not have access to a take-back program.
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
