- Is Ritalin Bad For You?
Ritalin is a brand name for methylphenidate hydrochloride, a prescription medication for attention deficit hyperactivity disorder (ADHD) and narcolepsy. Though it’s considered safe when used under a doctor’s supervision, it can have short-term and long-term side effects.
If you abuse Ritalin by taking it against medical advice—without a prescription, in higher doses, more frequently, or longer than prescribed—you raise your risk of experiencing adverse side effects and becoming dependent on it.
Short-Term Effects Of Ritalin
As a stimulant medication, Ritalin increases the action of some neurotransmitters (chemical messengers) in the brain, including norepinephrine and dopamine.
Ritalin is a central nervous system stimulant as well, and works similarly to Concerta (extended-release methylphenidate) and Adderall (amphetamine).
The short-term effect of Ritalin is greater concentration and energy levels, which decreases ADHD symptoms. Some people feel euphoria when they take Ritalin, which is one reason they abuse it.

Ritalin Drug Interactions & Risky Conditions
Some drugs aren’t safe to take with Ritalin. If you’re on these medications, your doctor needs to know. If you’re abusing Ritalin, doing so while taking certain other drugs increases your risk of complications.
Drugs that interact with Ritalin include (but are not limited to):
- monoamine oxidase inhibitors (MAOIs): isocarboxazid (Marplan), linezolid (Zyvox), methylene blue, phenelzine (Nardil), selegiline (Eldepryl), tranylcypromine (Parnate)
- selective serotonin reuptake inhibitors (SSRIs): citalopram (Celexa), escitalopram (Lexapro), fluoxetine (Prozac), paroxetine (Paxil), sertraline (Zoloft)
- blood thinners
- heartburn or ulcer medication
- high blood pressure medication
- seizure medication
- some natural supplements
Some pre-existing health conditions increase the risk of adverse side effects if you take Ritalin. These conditions include:
- Tourette’s syndrome
- overactive thyroid
- a heart condition (or family history)
- anxiety, tension, or agitation
Ritalin Long-Term Effects
Ritalin use can have long-term effects on your body and mind, even with prescribed use. Abusing Ritalin can lead to addiction and more adverse health consequences.
Increased Heart Rate & Blood Pressure
Ritalin can increase your heart rate, blood pressure, and energy levels. If your doctor prescribes Ritalin, they will likely monitor you for tachycardia (rapid heart rate) or hypertension (severe high blood pressure).
Abusing Ritalin raises your risk of having a heart attack or stroke. If you have a heart condition, it’s more dangerous to take Ritalin, and the drug could cause additional heart problems.
Mental Health Symptoms
As a stimulant, Ritalin may make it difficult to sleep. Lack of sleep, paired with raised blood pressure and heart rate can worsen anxiety or give you mood swings. Ritalin use can lead to worsened symptoms of other pre-existing mental health disorders.
Digestion & Nutrition Issues
If you have a decreased appetite while taking Ritalin, you may struggle with malnutrition and weight loss. Ritalin can cause other digestive issues, such as stomachaches, nausea, and diarrhea.
Addiction & Dependence
The US Drug Enforcement Administration (DEA) classifies Ritalin as a Schedule II controlled substance with a high potential for abuse and addiction. It’s addictive because it activates the brain’s reward system by increasing feel-good chemicals like dopamine.
When you’re rewarded with a pleasant sensation from a drug, your brain responds by desiring that drug again. If you continue to seek the reward from Ritalin, you rewire your brain to crave it.
Addiction makes it hard to stop taking a drug or to find the same pleasure from any other source.
Long-Term Effects Of Ritalin Abuse
Many people who abuse Ritalin do so by taking it orally in pill form. But some people crush it to snort or inject. These methods of abuse come with unique risks and potential long-term effects.
Abusing Ritalin by snorting (insufflation) damages the nasal tissue and can lead to:
- whistling breath
- difficulty swallowing
- sore throat
- lung problems
- erosion between the nostrils or through the roof of the mouth
Ritalin injection is hard on veins and blood vessels, posing the risk of:
- clogged blood vessels
- abscesses (pus-filled skin at the injection site)
- scarring (track marks)
- collapsed veins
- disease transmission (from shared needles)
Snorting and injecting Ritalin causes the drug to reach your bloodstream all at once, rather than passing through your digestive system and being gradually distributed in your body.
Ritalin SR (sustained-release) and Ritalin LA (long-acting) are formulated to enter the body slowly throughout the day. Taking them by snorting or injection can cause an overdose.
Is Ritalin Bad For You?
When used as directed, Ritalin (methylphenidate) can help people with ADHD or narcolepsy live a more manageable life. However, anyone may have unpleasant side effects while taking the drug.
If the side effects you experience lower your quality of life, talk to your doctor. They may be able to remedy the problem by adjusting your dosage or switching you to a different drug.
