Ritalin is a brand name of a stimulant drug called methylphenidate.
Ritalin stimulates the mind and body in adults and can calm children down. It's used to treat attention deficit hyperactivity disorder (ADHD) in children. However, it’s not usually recommended for children younger than 6 years old. It can help people who have ADHD pay attention to tasks better and decreases impulsive and hyperactive behaviour. In adults it's used to treat narcolepsy (extreme sleepiness).
Some people misuse Ritalin to get high. People who misuse it might crush it into a powder. They snort it, or dissolve and inject it. College or university students might misuse Ritalin because they think it will help them focus better on their studies by making it easier to pay attention and stay alert.
Some people who misuse Ritalin might feel high or excited, even when only low doses are taken. Others feel more excited when a high dose is taken. When misused, the drug can make people feel more alert or sleepier. Often they’re more awake right after they take it, but then they get very tired.
Very high doses can make you very agitated and restless and confused (delirious). You could have seizures, serious heart rhythm changes, and even end up in a coma.
The most common side effects of using Ritalin for a long time are:
People who misuse high doses of Ritalin every day can become paranoid or hallucinate. This seems to go away when they stop using the drug but this may take some time. Sometimes these effects don't completely go away.
Ritalin pills contain fillers that don’t dissolve when they’re crushed. These fillers can get into the lungs and cause breathing problems or lung disease.
People who misuse Ritalin for a long time eventually need to take more of the drug to get the same effects (tolerance). They can get dependent on the way it makes them feel. They may panic if they can’t get more, and crave it if they try to stop using it. They can also become physically dependent. When they stop using, they can feel very tired and get depressed.
It's against the law to carry (if you don’t have a prescription) or sell methylphenidate. You can be fined, get a criminal record, or go to jail.
