Mesoridazine Oral

Mesoridazine is used to treat the symptoms of schizophrenia and reduce restlessness, anxiety, and tension. It can also reduce hyperactivity and uncooperativeness.

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.
