Methylphenidate is a medication used to stimulate the central nervous system in the brain with an action similar to, but milder than that of amphetamines. One difference that methylphenidate has over amphetamines is that it noticeably produces more affects on mental activities than on motor ones. It has a calming affect on children when used to treat attention-deficit hyperactivity disorder or ADHD. Methylphenidate is also known to reduce hyperactivity in children and an increase in the attention span when children with ADHD are treated with methylphenidate. Methylphenidate and amphetamines can both lead to drug abuse. Methylphenidate has been approved by FDA since as long as 1955.

Patients who have been treated with this medication for ADHD will show better attention span and a reduction in impulsiveness and hyperactivity.

How to use methylphenidate

The instructions in the medication guide should be thoroughly understood before you begin on methylphenidate and each time you buy a refill. Also ask the doctor or pharmacist to explain what is not understood.

The medication will normally be taken 30 to 45 minutes before a meal unless the doctor has directed you differently. In case of a stomach upset or loss of appetite the medication will be taken with or either after meals or snacks.

The best benefits will ensue with regular use of methylphenidate, so remember to take it at the same time daily. Only after two weeks of regular use of the medicine will the improvements begin to show. The dosage of the medication is based on the patient's medical condition and the response to therapy, so make sure to take the medication exactly as prescribed as the medication is habit forming.

There could be chances of addictive behaviour, though not likely, and so doses must not be increased, taken more frequently or used over longer periods of time than prescribed. Your doctor will know when to increase or decrease the medication and so do not suddenly stop using it without asking the doctor for advice, particularly if taken for long already. Once the medication has been stopped it should remain stopped so that there are minimal chances of addiction.

If methylphenidate has been used over a long period of time and is stopped there could be withdrawal symptoms like severe depression and over activity. To prevent any such reactions the doctor is likely to decrease the dose very gradually. Report any withdrawal symptoms to the doctor; consult him or the pharmacist if you would like more details.

Besides the medication can become ineffective when used over long periods of time and the doses may have to be adjusted. You must talk to your doctor if you feel the medication is no longer working especially if conditions remain the same or worsen.

How methylphenidate works

Methylphenidate is said to be working when norepinephrine, a natural hormone that transmits nerve impulses in the brain, is encouraged to release with the help of the medication. This will decrease restlessness and increase attention in both adults and children, who have problems concentrating, are distracted and very impulsive.
