Vyvanse and Ritalin are two medications that can be prescribed to treat Attention-Deficit Hyperactivity Disorder (ADHD) in adults and children. There are some similarities between the two medicines. There are also some big differences. 

When choosing a medication to treat ADHD, doctors have a lot to consider before deciding which one to prescribe. Both Vyvanse and Ritalin can be medications your doctor could choose to treat you or your child. It is important to understand Vyvanse and Ritalin, how they treat ADHD, and their side effects before taking them.

 

What is Vyvanse?

Vyvanse is an ADHD medication for adults and children over age 6. It can also be used to treat binge eating disorder in certain people.

The active ingredient in Vyvanse is lisdexamfetamine dimesylate. It is a stimulant and a Schedule II controlled substance because it has a high risk of misuse and dependency.

Vyvanse is a medication that is taken once a day. It is usually prescribed in one of the following ways:

  • Chewable tablet, ranging from 10-60 mg
  • Capsule, ranging from 10-70 mg

Doctors usually start at a lower dosage and adjust as needed until the right dose is reached.

Vyvanse Side Effects

Vyvanse has several side effects that could occur during usage. There are some serious side effects, but most are mild. They often go away after using the medication. These can include:

  • Mild side effects:
    • Insomnia
    • Decreased appetite
    • Nausea
    • Feeling anxious or jittery
    • Dizziness
    • Dry mouth
    • Weight loss
    • Mood changes/irritability 
    • Diarrhea
  • Serious side effects:
    • Serious cardiovascular reactions
    • Circulation problems, especially in the fingers and toes
    • Mental health problems such as psychosis or mania
    • Serotonin syndrome
    • Allergic reaction
    • Misuse or dependence
    • In children, slowed growth

The serious side effects are less common but should not be ignored. If you experience any of these, contact your doctor right away. Your doctor may determine that you need a different medicine.

 

What is Ritalin?

Ritalin is also a prescription medicine used to treat ADHD in children aged 3+ and adults. The active ingredient is methylphenidate and it is a central nervous stimulant.

Ritalin helps increase concentration in a person with ADHD. Ritalin can also be prescribed for narcolepsy in patients 6 years and older.

Ritalin can be prescribed in immediate- or extended-release. Immediate is available in 5 mg, 10, and 20 mg. Ritalin-SR and Ritalin-LA are extended-release. They are available in 20 mg (SR) and in 10, 20, 30, and 40 mg (LA).

Many doctors will start children at a dosage of 2.5 mg twice daily, gradually increasing the dose each week by 5-10 mg but not exceeding 60 mg. The usual starting adult dosage is 10-20 mg a day. The maximum dose is 60 mg per day.

Ritalin Side Effects

There can be several side effects when taking Ritalin. There are some mild, more common side effects. These should pass quickly and lessen with use. These include:

  • Very common:
    • Nervousness
    • Insomnia
    • Dry mouth
    • Decrease in appetite 
  • Common:
    • Anxiety or agitation
    • Feeling restless or jittery
    • Headache
    • Dizziness 
    • Nausea or vomiting
    • Heartburn
    • Increased heart rate or blood pressure
    • Rash
    • Fever
    • Weight loss

There can be more serious side effects when taking Ritalin. If any of these are experienced, your doctor should be contacted immediately. Those can include:

  • Convulsions
  • Tics
  • Heart problems
  • Visual disturbances
  • Blurry vision
  • Muscle cramping
  • Severe allergic reactions

 

How Do Vyvanse and Ritalin Compare?

There are similarities and differences between these two medications. Both Vyvanse and Ritalin are prescription stimulants used to treat ADHD. They both increase dopamine and norepinephrine in the brain. And they both have a potential for misuse or abuse.

There are some significant differences, however. The biggest difference is in the active ingredient. The active ingredient in Vyvanse (lisdexamfetamine dimesylate) enters the body in its inactive form. This means the body processes it to its active form. This means it will not be effective for 1-2 hours after taking it. However, these effects last much longer through the day, even up to 13-14 hours.

The active ingredient in Ritalin (methylphenidate) is already in its active form when it enters the body. Therefore, it starts working immediately. But, the effects of Ritalin only last between 3-5 hours.

Vyvanse can be taken less often each day than Ritalin. This is a significant difference between these two medicines.

Your doctor should be aware of all types of medication you take, including herbs and supplements. Many things have the potential to interact with Vyvanse or Ritalin. Drug interactions can have serious side effects or change how effective medications are.
