About Ritalin
Ritalin has some serious risks. After taking Ritalin, some patients have experienced:

  • Psychiatric symptoms, including behavior and thought problems, bipolar illness, aggressive behavior and hostility, hearing or seeing things that are not real, believing things that are not real, or becoming overly suspicious of things
It is important that you talk with your doctor about any factors that may put you at greater risk for serious side effects before taking Ritalin.

Tell your doctor if you are pregnant, breast-feeding, or planning to become pregnant. If you become pregnant while taking Ritalin, notify your doctor. Also, let your doctor know if you have ever had a reaction to any medicines, especially Ritalin or medicines similar to it. Let him or her know about any other medicines you take. Some may have dangerous reactions with Ritalin. You should never take Ritalin within 14 days of taking a monoamine oxidase (MAO) inhibitor, for instance.
