Ritalin (methylphenidate) is used as part of attention deficit hyperactivity disorder or ADHD treatment in adults and children, and narcolepsy. Ritalin is abused when you take it without a medical prescription, in larger doses or at higher frequencies than suggested. However, this type of use can lead to acute toxicity.

So, can you overdose on Ritalin? Yes! How much Ritalin can cause an OD? What are the consequences of a Ritalin overdose? We provide the answers to these questions in this article. At the end, we welcome your questions. We’ll try to answer each one personally and promptly.

How does unintentional Ritalin overdose happen?

An unintentional overdose (OD) can occur when a drug is taken in high doses by an individual without the intent to self-harm. This includes accidental overdose on prescription or recreational drugs.

Unintentional Ritalin overdose can be the unwanted result of:

  • recreational Ritalin misuse
  • chronic Ritalin abuse
  • taking too much Ritalin for medical reasons
  • mixing Ritalin with other psychoactive substances

How do experts recommend that we stop unintentional overdose? Continued efforts to prevent ODs through education and enforcement needed within medical systems. In fact, we urge pharmaceutical companies directly to work with the public, health organization, and other relevant stakeholders, but we still believe this: prescription drug education, abuse and diversion prevention starts at home.

Ritalin overdose – How much is too much?

How much Ritalin is too much for a person depends on a few factors:

  • the individual
  • the condition being treated
  • physical health
  • age
  • body mass
  • developed tolerance to methylphenidate

…and other factors. The average daily dose of methylphenidate for adults is 20 to 30 mg/day. Most recommendations suggest that the daily Ritalin dose should not exceed 60 mg, although some individuals may require higher doses. Furthermore, the safe and recommended dosage range for children who are on Ritalin varies from child to child.

The instructions for safe use are clear:

  • Do not take larger doses.
  • Do not take it more often than suggested.
  • Do not take it in a different way than prescribed.
  • Do not take it longer than the duration of your treatment.
  • Do not take it if you do not have a prescription from a doctor.

Using too much Ritalin can also be habit-forming. Before you get a prescription for Ritalin, tell your doctor if you drink regularly or excessively, if you use or have ever used street drugs, or have had problems with prescription medication abuse. This information can help prevent drug addiction and problems down the road.

Ritalin overdose complications

Can you die from taking Ritalin? Yes…

Acute toxicity due to Ritalin overdose results in symptoms similar to those of acute amphetamine intoxication. Some common symptoms that can signal you have taken too much Ritalin, include:

  • racing heart or abnormal heart rhythm
  • excessive sweating
  • high anxiety or panic
  • increased body temperature
  • muscle cramps or twitching
  • tingling or numb sensation in hands and feet
  • rapid, shallow breathing
  • dizziness or lightheadedness
  • nausea or vomiting
  • restlessness or agitation
  • rapid thoughts and speech
  • confusion
  • chest pain
  • extremely dry mouth

Such symptoms might be expected when Ritalin is used in high or frequent doses, as Ritalin’s effects are “basically the same as those of amphetamines”. Cases of psychosis with Ritalin abuse have been reported when the drug is used in “runs”, similar to amphetamine abuse.

IMPORTANT: If you or someone close to you take too much Ritalin, you should seek emergency medical attention, or call your local Poison Control Center at 1-800-222-1222. If the victim has collapsed or is not breathing, call 911.

Ritalin overdose prognosis

Ritalin overdose can occur at significantly higher doses than most prescription doses. But, if you don’t have a tolerance to Ritalin and you are a recreational or first time user, you can OD by taking more than your body can handle to process. If you feel unwell after using Ritalin or experience a few of the overdose symptoms, you should ask someone who is sober to drive you to the ER or seek medical help ASAP.

CONSIDER THIS: Ritalin SR (sustained release tablets) have a duration of action of approximately 8 hours. If you have taken Ritalin SR, it is possible that the symptoms may get worse and more problematic as the drug continues to release into the body. Symptoms may also be exacerbated if you take other stimulant drugs (or even caffeine) along with Ritalin.

Ritalin overdose death rate

Drug overdose death rates in the United States have more than tripled since 1990 and have never been higher. In 2008, more than 36,000 people died from drug overdoses, and most of these deaths were caused by prescription drugs.

Ritalin overdose can be fatal especially in individuals with certain health issues. Ritalin and other stimulants are not recommended for children or adolescents with known serious structural cardiac abnormalities. Adults do not face lesser risks with Ritalin, as they are more likely to have serious structural cardiac abnormalities, such as:

  • cardiomyopathy
  • serious heart rhythm abnormalities
  • coronary artery disease
  • other serious heart problems
