There are newer medications being developed and undergoing clinical testing, including a long acting 10-hour formulation of methylphenidate. The length of time a person takes a medication depends on each individual. Everyone is different. Some people only need a short treatment, for 1 to 2 years, while some people need treatment for years. Regular checkups with your doctor should always be a part of this process.
All medications can have side effects.
Medications that are used to treat Attention Deficit Disorders are no different. Psychostimulants may cause a decrease in appetite, stomachache or headaches. Usually, these effects are limited to the initiation of the medications and get better with time. Too strong of a dose may produce jitteriness, increased heart rate or sluggishness. Loss of appetite will result in weight loss for some people.
