Ritalin
Ritalin, Concerta, Metadate, Methylin, and Rubifen are brand names for methylphenidate hydrochloride, an amphetamine-like prescription stimulant commonly used to treat AD/HD in children and adults. It is also one of the primary drugs used to treat symptoms of traumatic brain injury and the daytime drowsiness of narcolepsy and chronic fatigue syndrome.
Ritalin was derived from Dexedrine in the 1950's in an effort to reduce that drug's side effects of appetite suppression and insomnia. Ritalin is the most frequently prescribed stimulant drug for AD/HD and is the focus of much of the controversy about stimulant drugs.
Ritalin is available in both short- and long-acting form. The short acting form generally begins working about 30 minutes after ingestion, peaks at two hours and diminishes in about four. It must be taken several times daily. Ritalin sustained-release tablets last about eight hours.
Ritalin affects children in the same way that related stimulants like cocaine affects adults. It sharpens the short-term attention span when the drug kicks in and produces equally predictable valleys when it wears off.
Possible side effects include insomnia, nervousness, drowsiness, dizziness, headache, blurred vision, tics, abdominal pain, nausea, vomiting, decreased appetite, weight loss, irregular or fast heartbeat, confusion, and liver damage (characterized by yellowing of the skin or eyes, nausea, abdominal pain or discomfort, unusual bleeding or bruising, and severe fatigue).
Possible symptoms of an overdose include agitation, anxiety, tremors, muscle twitches, seizures, confusion, hallucinations, sweating, headache, fast or irregular heartbeat, large pupils, and dryness of the mouth and eyes.
Ritalin has potential for abuse and for physical and psychological dependence, especially among people who do not have AD/HD. Continued Ritalin use can build up a tolerance to the drug and eventually require larger doses to reap the same effects. Once discontinued, withdrawal effects such as depression may occur.
Adderall
Adderall is a "cocktail" drug that combines four drugs from the amphetamine family. It was first developed about 20 years ago under the name Obetrol, and was marketed for weight loss. The FDA first approved it for unrestricted use for the treatment of ADD and ADHD (AD/HD) in 1996.
The effects of Adderall can be felt after only a few doses but often takes up to a week or more to achieve the full effect. One dose lasts about six hours. Doctors and people using Adderall report that it can be less "harsh" than Ritalin, with fewer peaks and valleys.
Possible side effects of Adderall include irregular heartbeat, increased blood pressure, restlessness or tremor, anxiety or nervousness, headache, dizziness, insomnia, dryness of the mouth or unpleasant taste in the mouth, diarrhea or constipation, impotence or changes in sex drive.
Possible symptoms of overdose include restlessness, tremor, rapid breathing, confusion, hallucinations, panic, aggressiveness, nausea, vomiting, diarrhea, irregular heartbeat, and seizures.
Like Ritalin, Adderall has potential for abuse and dependence, especially among people who do not have AD/HD. Continued use can result in tolerance to the drug, necessitating an increase in dosage to reap the same effects. Once discontinued, withdrawal effects such as depression may occur.
