Ritalin 20 mg Tablets

Of the three strengths available for Ritalin^® (methylphenidate hydrochloride), the 20 mg tablets are the strongest strength on the market. This prescription medication is used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy. Ritalin tablets are typically taken by mouth two or three times a day. Usually, the last dose of Ritalin should be taken before 6 p.m. (taking it later could cause difficulty sleeping). The medication can be taken with or without food, although it is usually taken 30 to 45 minutes before meals.

 

For children age 6 and over, Ritalin should be started at 5 mg twice daily (before breakfast and lunch). If necessary, your child's healthcare provider may slowly increase the dose up to Ritalin 60 mg per day (or Ritalin 20 mg tablets taken three times a day).

 

For adults with narcolepsy, the total dosage of Ritalin per day is usually 20 mg to 30 mg (divided into two or three doses). Some people may need less Ritalin, while others may need as much as 60 mg per day.
