WHY is this medicine prescribed?
Mesoridazine is used to treat the symptoms of schizophrenia and reduce restlessness, anxiety, and tension. It can also reduce hyperactivity and uncooperativeness.
HOW should this medicine be used?
Mesoridazine comes as a tablet and liquid concentrate to take by mouth. It is usually taken two or three times a day. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take mesoridazine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
The liquid concentrate must be diluted before use. It comes with a specially marked dropper for measuring the dose. Ask your pharmacist to show you how to use the dropper if you have difficulty. To dilute the liquid concentrate, add it to at least 2 ounces (60 milliliters) of water, orange juice, or grape juice before taking it. If any of the juice gets on the dropper, rinse the dropper with tap water before replacing it in the bottle. Do not allow the liquid concentrate to touch your skin or clothing; it can irritate your skin. If you spill the liquid concentrate on your skin, wash it off immediately with soap and water.
Continue to take mesoridazine even if you feel well. Do not stop taking mesoridazine without talking to your doctor, especially if you have taken large doses for a long time. Your doctor probably will decrease your dose gradually. This drug must be taken regularly for a few weeks before its full effect is felt.

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). Protect the liquid from light.
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
