From a historical perspective, one of the most popular ADHD medications of all time is Ritalin. It was first approved by the FDA in 1955 for treating a condition referred to as “hyperactivity.” While there weren’t many diagnoses for hyperactivity in the 1950s, the number of diagnoses skyrocketed in the 1990s, making Ritalin the single most popular pharmaceutical for the treatment of the condition now known as attention-deficit hyperactivity disorder (ADHD).
Ritalin has been around for well over half a century (nearly 60 years) and has been subject to extensive research. Although Ritalin is still heavily prescribed throughout the world, it no longer is the dominant drug of choice for treating ADHD. Nearly 40 years after the inception of Ritalin, a psychostimulant medication known as “Adderall” was engineered by Shire Pharmaceuticals.
Adderall gained steady momentum for its efficacy in treating attentional deficits. It also gained widespread acclaim as a stimulant that could be used as a party drug or to achieve a state of psychological euphoria. Despite the fact that Adderall and Ritalin are both psychostimulant drugs, there are subtle differences in the ingredient composition as well as mechanisms of action.

Ritalin vs. Adderall: What’s the difference?
As you can see by the chart above, these drugs have some obvious similarities and some subtle differences. Adderall is a newer drug comprised of mixed amphetamine salts, whereas Ritalin contains methylphenidate. Both are considered effective agents for the treatment of ADHD and each is classified as a “Schedule II” controlled-substance in the United States.
The formatting and effect duration of each drug is slightly different. Ritalin is manufactured in three formats: an instant release (IR) lasting 3-4 hours, sustained release (SR) lasting 6 to 8 hours, and long-acting (LA) lasting 8 hours. Adderall is limited to two formats: an instant release (IR) lasting 4 to 6 hours and extended release (XR) lasting 12 hours.
Both Adderall and Ritalin are thought to have a high potential for abuse and dependence, therefore they are classified as “Schedule II” controlled-substances. This means that those taking Adderall or Ritalin may end up taking more than the prescribed amounts to achieve a psychological “high” characterized as a stimulatory euphoria. This psychological high is a result of high concentrations of dopamine being released.
Many partygoers take Adderall and/or Ritalin as means of inducing a psychological euphoria as well as to mitigate some of the psychological impairment associated with alcohol consumption. Those who abuse these drugs may resort to administering the substances with non-medically approved modalities such as insufflation or injection. It is common for individuals to resort to snorting Adderall as a quicker way to get high compared to oral ingestion.
The abuse potential is not limited to partygoers – many college students take Adderall and Ritalin to improve their academic performance. Many end up becoming dependent on these substances in order to perform well on tests or get passing grades. Tolerance is quickly built-up to each of these substances, making them both popular drugs of abuse. Adderall may have slightly more abuse potential due to the fact that it is thought to elicit a greater “rush” than Ritalin.
Cost: Which is more expensive?
If you want to purchase the respective generic versions of Ritalin (methylphenidate) and Adderall (mixed amphetamine salts) you can save yourself quite a big chunk of change compared to the “brand names.” The cost of generic versions of Ritalin and Adderall tend to be relatively similar – approximately $50 for a 30 day supply. You may be able to attain Ritalin for less than Adderall depending on your pharmacy.
That said, the sustained-release and long-acting versions of Ritalin are still fairly costly – even for generics. The generic sustained-release version is usually a minimum of $50 and the generic long-acting is a minimum of $70 for a 30 day supply. The generic Adderall XR costs a minimum of $75 most places for a 30 day supply – making Adderall slightly more expensive for generics than Ritalin.
The brand name versions of Ritalin and Adderall are both relatively expensive. Brand name immediate-release Ritalin costs approximately $95 whereas brand name immediate-release Adderall costs nearly $300. Upon cost comparison, it becomes obvious that immediate-release Ritalin can be attained for a fraction of the price of immediate-release Adderall. However the extended release Adderall cost (+$220) is comparable to long-acting Ritalin (+$218).
Dosage & Formats
There are subtle differences in dosage and formats of Ritalin and Adderall. Ritalin can be taken in the format of instant release (IR), sustained release (SR), or long-acting (LA) form. Adderall is limited to two formats of: instant release (IR) and extended release (XR). The instant release version of Adderall is thought to last 4 to 6 hours, whereas the instant release version of Ritalin is shorter acting at only 3 to 4 hours.
A dosage of 5 mg Adderall is thought to be equivalent to approximately 10 mg of Ritalin. Adderall is manufactured in more dosing variations such as 5 mg, 7.5 mg, 10 mg, 12.5 mg, 15 mg, 20 mg, and 30 mg for the immediate release. These smaller increments may be preferred by doctors and patients due to the fact that they make it easier to titrate upwards or downwards with the dose.
Ritalin is more limited in their dosing options and is formatted in only 5 mg, 10 mg, and 20 mg tablets for their immediate release (IR). Adderall is thought to have the more versatile dosing options, whereas Ritalin’s formatting in short-acting, moderate-acting, and long-acting options may be preferred by some individuals.
Efficacy: Which drug is more effective?
The biggest component associated with comparing Ritalin and Adderall is determining the efficacy. Both medications are considered clinically effective for the treatment of ADHD and narcolepsy, meaning they both stood the test of randomized, double-blind, placebo-controlled studies. That said, studies have made attempts to compare the medications on a head-to-head basis in order to determine whether one may be more effective than the other for reducing attentional deficits.
An 8-week study with 25 children diagnosed with ADHD compared the efficacy of Ritalin, Adderall, and a placebo. They received either Ritalin 10 mg or 17.5 mg, Adderall 12.5 mg, or a placebo. These were administered twice per day (once in the morning and once in the afternoon). Results demonstrated that both drugs were significantly better than a placebo for behavioral improvements, academic productivity, and staff/parent ratings of behavior.
Researchers noted that Adderall produced a greater improvement than Ritalin on most measures. Authors of the 1999 publication note that Adderall was functionally more potent at the given doses than Ritalin. Another study published the same year compared 42 youths treated with Adderall to 42 youths treated with Ritalin.
They analyzed how a single dose of Adderall compared to a 2 doses of Ritalin. The researchers concluded that one dose of Adderall was equal in efficacy to the 2 doses of Ritalin. They suggested that Adderall may be preferred over Ritalin due to reduced treatment management (i.e. only administering one dose).
Another comparison publication published in 2000 analyzed how 25 mg of Ritalin compared to 12.5 mg of Adderall among 58 children. Results suggested that Adderall was favorable over Ritalin and the behavioral improvements were longer-lasting after single doses. While both drugs produce improvement in attentional deficits, Adderall may be slightly more effective.

Mechanisms of action…
The reported subjective effects of both Ritalin and Adderall are considered similar. Both drugs function as psychostimulants and increase concentrations of dopamine and norepinephrine. Ritalin is comprised of methylphenidate, which is thought to act as a “pure uptake inhibitor” without other presynaptic activity. The mixed amphetamine salts within Adderall are thought to elicit additional presynaptic activity releasing dopamine and norepinephrine from presynaptic neurons.
Ritalin is known to have a shorter half-life than Adderall, meaning it is more rapidly excreted. There are thought to be some differences in the way each drug is excreted from the body. Ritalin is thought to metabolize into 80% inactive molecules and 20% to an active metabolite. The mixed amphetamine salts in Adderall are believed to be excreted via urine.

From a medical perspective, both Ritalin and Adderall are used to treat similar conditions. They are each considered effective first-line treatments for ADHD and narcolepsy. They also are utilized on an off-label basis as an antidepressant augmentation strategy for individuals with treatment-resistant depression. They do differ slightly in terms of other medical investigational uses.
Ritalin has been investigated as a treatment for POTS (postural orthostatic tachycardia syndrome), lethargy, obesity, aggression, and criminality. Due to the fact that both drugs elicit similar stimulatory effects, it could be speculated that both would have similar investigational uses. In some cases they may be tested as counterintuitive interventions for individuals suffering from refractory anxiety. (Read: Adderall for anxiety disorders).
In regards to popularity, Adderall is the single most popular psychostimulant medication on the market. As of 2013 an estimated 38% of all psychostimulant prescriptions were of Adderall. By comparison, an estimated 23% of all psychostimulant prescriptions were for methylphenidate. Ritalin is just one brand name of medication that is comprised of the ingredient methylphenidate.
Based on the sheer number of prescriptions alone, Adderall is more popular. Millions of people are known to be taking Adderall, whereas only hundreds of thousands are thought to be taking Ritalin. Much of the popularity is in regards to the slightly increased efficacy of Adderall over Ritalin as well as the fact that it’s newer.
The side effect profiles of both Ritalin and Adderall are similar. Both are stimulatory medications designed to speed up activity in the central nervous system. Both increase extracellular levels of dopamine and norepinephrine. As a result, there is often significant overlap in side effects such as: anxiety, appetite loss, insomnia, nervousness, and weight loss.
Both stimulants have been documented as stunting the growth of youth. Although short-term stunting of growth is common (i.e. 1 inch), it is believed to be temporary, ultimately not affecting an individual’s final adult height. Each of these drugs also can also provoke “stimulant psychosis” when used at high doses over a long-term.
In addition to reduced height, individuals taking these stimulants tend to also be thinner – weighing less than non-medicated counterparts. For this reason, many people use Adderall for weight loss, despite its lack of FDA approval for obesity. Many people have had success in using Ritalin off-label to lose weight as well.
Ritalin and Adderall are both difficult to discontinue due to the fact that they are habit forming. Those taking either of these drugs may quickly build tolerance and ultimately have a difficult time functioning without the drug, especially after moderate or long-term usage. The difficulty of withdrawal is generally dictated by the dosage taken and duration over which it was taken.
While the medical community may downplay the severity of both Ritalin withdrawal and Adderall withdrawal, those taking the drugs know better. Over a long term, both drugs downregulate dopamine and dopamine receptors. This results in low dopamine levels upon discontinuation, which exacerbates attentional difficulties and hyperactivity.
Furthermore, many anecdotal reports suggest that withdrawal is often protracted, lasting months (or in some cases years) before attentional capacity and full cognitive function is restored. These substances carry risk of dependence. Those that have been taking them for a long term may not be able to face the withdrawal symptoms nor function (at work or school) without the aid of either drug.
Similarities (Recap): Ritalin vs. Adderall
Below is a recap of some general similarities between Ritalin and Adderall.

- Side effects: The side effect profiles of Ritalin and Adderall are similar in that they both may provoke nervousness, insomnia, anxiety, and result in appetite suppression.
- Withdrawal: Discontinuation from these medications is thought to be difficult due to the fact that a person may have become dependent upon high doses for enhanced cognition. Withdrawal symptoms often include: fatigue, low energy, sleepiness, and psychomotor depression.
Differences (Recap): Ritalin vs. Adderall
Below is a recap of some general differences between Ritalin and Adderall.
- Cost: Although the cost for the extended release (XR) Adderall and long-acting (LA) Ritalin are similar, the cost of the immediate-release (IR) versions of each drug is significantly different. Brand name Ritalin (IR) can be purchased at a fraction of the price of Adderall (IR).
- Duration of effect: The duration of effect differs slightly between the immediate-release versions. Adderall is thought to deliver an effect for 4 to 6 hours, whereas Ritalin is only thought to be active for 3 to 4 hours.
- Efficacy: Results from some studies in the late 1990s/early 2000s suggest that Adderall may be superior in efficacy to Ritalin. While the superiority of efficacy may not be statistically significant, it may be enough for patients to prefer Adderall over Ritalin.
- Formats: Ritalin is available in three different formats (IR, SR, LA) and Adderall is available in two formats (IR and XR). While they both share an immediate-release format, the duration of effect for each format is different.
- Half-life: The half-life of Adderall (11 to 13 hours) is notably longer than that of Ritalin (1 to 7 hours).
- Ingredients: Ritalin is comprised of methylphenidate and Adderall is comprised of 75% dextroamphetamine / 25% levoamphetamine (mixed amphetamine salts).
- Investigational uses: Ritalin has been investigated for the treatment of aggression and criminality. Adderall has been tested as an aid in the rehabilitation of stroke patients.

Which drug is better for ADHD? Ritalin vs. Adderall.
Everyone considering a psychostimulant (or currently taking one) wants to know if the drug they’re taking is the “best.” Both of these substances are considered clinically effective for the treatment of ADHD and narcolepsy symptoms. That said, several studies suggest that Adderall is more effective and longer-lasting at an estimated equivalent dose to Ritalin.
Furthermore, many people prefer Adderall due to the fact that it doesn’t need to be taken as frequently as Ritalin – potentially reducing the number of pills ingested per day. There is no definitive evidence suggesting that Adderall works better than Ritalin, but one study from 1999 indicated that Adderall produced longer-lasting behavioral improvements in youth than Ritalin.
It is important to realize that responses to each drug are subject to significant individual variation. Some people may find that Ritalin works better with less side effects for treating their ADHD, while others may find that Adderall packs a comparatively favorable punch. Others may find that neither drug works all that well or that both carry unwanted side effects. It is important to avoid thinking that one drug is significantly “better” than the other until evidence proves it.
Which drug do you prefer: Ritalin or Adderall?
If you’ve tried Ritalin and Adderall, feel free to share which drug was more helpful for treating your symptoms of ADHD or narcolepsy. Did you experience more side effects or unwanted effects from one drug compared to the other? Some people claim to experience a “cleaner focus” on Ritalin compared to Adderall, whereas others prefer to use Adderall because it eradicates their ADHD to a greater extent.
10 thoughts on “Ritalin vs. Adderall: Comparison”
I have taken both Methylphenidate IR (20mg TID) (Amphetamine Salts IR 30mg BID), obviously the Adderall is way more potent, and yes it is convenient to just have to take it bi-dailey vs. TID, I do still take Adderall because it is effective with my ADHD, but mainly it also helps “counteract” the side effects of my other medications (Alprazolam 1mg TID, MS Contin 60mg BID, Oxycodone HCL 10mg TID, Clonidine 0.3 BID, Metoprolol IR 50mg BID, Clonazepam 2mg BID) more so than the Methylphenidate.
Having said that, as far as this discussion, the fact is methylphenidate, even though less potent, DOES give one a more clear focus, I’ve had others tell me the same thing who have been on both. The only reason I no longer take Methylphenidate is because it doesn’t counter the depressant and sedative effects of other medications I have to take to live a normal life, because simply put, its not potent enough.
So, I realize my case is complex, but if you ONLY have ADHD, and want real HELP and aren’t worried about doping or getting high, like I said, real ADHD, REAL help for it, Methylphenidate is the answer to your question, hands down, and the best for ADHD, tried and proved. Unless you have an underlying medical condition where you need something for ADHD, but also something to help counteract the sedative effects of other medications you have to take, go with methylphenidate, it provides a much more clearer focus, verses Amphetamine Salts, where you are still focused, but try to do 50 things at once, and really have to know how it works and have to have self discipline to help let it help you!!!
Please!!! Go with, and especially start with, Methylphenidate. It’s the lesser of the two evils, less addictive mentally and works better addressing your ADHD. CONCLUSION, if you are seeking these medications for diversion or abuse, you should be in jail or rehabilitate yourself professionally, but the obvious answer is that Amphetamine Salts is highly more potent, if used over therapeutic dosages, provides one way more euphoria, it’s the preferred drug of choice out of all of the CNS stimulants on college campuses and the streets.
PLEASE CONSIDER THIS THE MOST IMPORTANT THING TO REMEMBER!!! Amphetamine Salts should be a last resort, after all other psycho-stimulants, narcotic and non-narcotic have been thoroughly tried and exhausted (for more than a few days, at least one month per medication to achieve and maximize full therapeutic benefits) before one should even consider going on Amphetamine Salts! If you and your health care provider conclude nothing else has worked and you, the patient, think this is what you need and your health care provider agrees, it’s still on you to weigh the pros and cons, and ultimately get that prescription filled or not.
Then once and if you do initiate treatment with Amphetamine Salts, I always recommend, and I want divulge my profession, to keep ALL controlled substances whether it’s CIV or CII, in a lock box or safe to prevent theft, diversion, and possibly a death. And always keep in my, your are responsible for narcotics prescribed to you, and unless they’re in, at least a cheap piece of junk box of some kind, with a lock or combination lock, you ARE responsible for the results of whatever happens if said medications are taken or stolen.
At the very least, legally you’re considered negligent, at the most responsible, involuntarily, for the results. Hope this helps, and provides some answers.
I am an adult nursing student and I take medicine daily for my ADHD. I began with Adderall and it seemed to work at first, then I needed more to get me through the day. My physician switched me to Vyvanse, but it was extremely more expensive. I am currently taking 40mg LA Ritalin, but my body is becoming more tolerant of this drug also. This article was very helpful and answered many questions that I had. Thank you very much and I look forward to any new updates on the drugs.
I’ve been taking Ritalin LA 40mg for almost 20 years now, and I feel it has become less effective than ever. I don’t feel that my focus and concentration is where it has been in the past, and I don’t feel energetic or awake anymore. I can function, but I feel as if it’s become such a struggle to “pull” it all together lately. I’m thinking of talking to my Dr. and switching my medications, and I really found this article to be helpful! Thanks for releasing this article! :)
I paid $165 for generic ritalin LA for a 30 day supply. (No insurance).
You can get it for much cheaper by printing out a prescription discount card from various sites online. I paid $25 yesterday for IR generic Ritalin.
Speaking from a medical student’s perspective here: This was a very well written article. Very concise, simple, and to-the-point; highlighted all the most important information on both drugs, effectively delineating the differences between them as well. Great to read for both lay-people, and as rapid review for those in the medical field as well.
Thank you for the comprehensive article. One item of note: generic Adderall goes for about $110 for a 30 day supply.
I pay less than $30 for a 30 days supply of generic Adderall with insurance. Otherwise, a person can download a prescription discount card online. $110 for 30 days is absurd.
This was the most comprehensive, precise and accurately understandable article I’ve found on the topic. Very helpful and informative. Thank GOODNESS! My Med Web search is over.
Well done! The information is consice, thorough and very readable for the general population. This article answered all of my questions and then some. I am printing a copy for future referral. Thank you!
