Key takeaways:
Ritalin (methylphenidate) and Adderall (mixed amphetamine salts) are stimulant medications that treat attention-deficit hyperactivity disorder (ADHD). They’re both considered first-choice options, but they contain different active ingredients.
Adderall’s effects generally last longer than Ritalin’s. But both medications also come in extended-release versions.
Side effects are similar between Ritalin and Adderall. Common examples are headache, reduced appetite, and dry mouth.
In general, Ritalin is preferred for kids and teens, while Adderall is preferred for adults. But there isn’t one ADHD medication that works best for everyone. Your prescriber can help determine which option is a better fit for you or your child.
Ritalin (methylphenidate) and Adderall (mixed amphetamine salts) are two of the most commonly prescribed medications for attention-deficit hyperactivity disorder (ADHD). But how do these two options compare? Let’s look at 4 things to consider when comparing Ritalin versus Adderall to help you determine which may be a better option for you.
1. Ritalin and Adderall contain different active ingredients
Stimulants are considered first-choice options for treating ADHD in adults and children. Ritalin and Adderall are both stimulant medications. But they contain different active ingredients.
Ritalin contains methylphenidate, while Adderall contains a mixture of dextroamphetamine and levoamphetamine. Both medications increase the levels of chemicals in the brain (dopamine and norepinephrine) that help you focus and reduce impulsive behaviors.
Search and compare options
But Ritalin and Adderall each have other effects in the brain that may contribute to how you respond to them. For example, Ritalin may also activate serotonin receptors, while Adderall can affect levels of other chemicals that control mood and attention, such as glutamate and serotonin. These may play a role in how you respond to these medications.
2. Adderall lasts longer than Ritalin, but both come in extended-release dosage forms
Ritalin typically starts working within 20 to 45 minutes of taking it and lasts for about 3 to 4 hours. Adderall also typically starts working within 30 to 45 minutes, but it lasts longer: about 4 to 6 hours.
If you’re taking an immediate-release version of these medications, you’ll likely need fewer doses of Adderall for effects that last throughout the day. But since it wears off faster, Ritalin gives you more flexibility when it comes to timing your doses around meals and in the evening before bedtime.
That being said, both Ritalin and Adderall also come in extended-release versions. The effects of Ritalin LA (methylphenidate ER) last for about 8 to 9 hours after your dose. The effects of Adderall XR (mixed amphetamine salts ER) last for roughly 8 to 12 hours after your dose. Mydayis, another brand name for mixed amphetamine salts, may last up to 16 hours per dose. These long-lasting options help reduce the number of doses you need to take each day. They may also be more convenient for school-age children.
Good to know: Methylphenidate, the active ingredient in Ritalin, is also available under many other brand names. This includes Concerta, Methylin ER, and Daytrana, among others. Each form of methylphenidate has a different onset and duration of action. Your prescriber can help you find the best form for your needs.
3. Ritalin and Adderall are approved for different age groups
Ritalin and Adderall are approved for different age groups, which may influence which is a better choice for you or your child’s needs.
Ritalin is FDA approved for adults and children ages 6 and older. Ritalin LA is approved only for children ages 6 to 12.
Adderall is approved for adults and children ages 3 and older. But Adderall XR is only approved for adults and children ages 6 and older.
Research suggests that Ritalin may work better for children and adolescents, while Adderall may work better for adults. So even though Adderall is approved for younger ages, clinical guidelines recommend prescribing Ritalin off-label as a first-choice medication option for children under age 6 when needed.
But everyone responds differently to medication. So what works for one person may not be the best option for you. Some trial and error is common when finding the right ADHD treatment for you or your child.
4. Ritalin and Adderall have similar side effects
Ritalin and Adderall have similar side effects to consider, such as:
Headache
Dry mouth
Decreased appetite and weight loss
Trouble sleeping
Mild increases in heart rate and blood pressure
Rare but serious side effects for both medications include heart problems, severe mood changes, and slower growth in kids and teens. Ritalin and Adderall are both controlled substances, so they also carry a risk of substance misuse and dependence.
Keep in mind that since Adderall lasts longer in the body, side effects may also last longer after taking it. If low appetite or sleep trouble is an issue, taking Ritalin may be a better option, since it doesn’t last as long.

Frequently asked questions
Yes, there are several nonstimulant medications that can help manage ADHD symptoms. Examples include Strattera (atomoxetine), Qelbree (viloxazine), and Intuniv (guanfacine ER). These aren’t considered first-choice options for ADHD. But they’re worth considering if you’re unable to take or tolerate stimulants.
No, in most cases you’ll only take one stimulant at a time. In some cases, your prescriber may combine a long-acting version with a short-acting version but in most cases both forms will contain the same active ingredient. For example, you may take Adderall XR in the morning, then a dose of immediate-release Adderall later in the afternoon. Your prescriber may also combine a stimulant and a nonstimulant to manage ADHD symptoms. That’s because these medications work in different ways.
