Vyvanse vs. Ritalin: What’s the Difference?

ADHD Treatments

Attention deficit hyperactivity disorder (ADHD) affects approximately
5 percent of children and 2.5 percent of adults in the United States, according
to the American Psychiatric Association.
The Centers for Disease
Control and Prevention (CDC) estimates that the numbers are higher. In a
survey, they found that 11 percent of children have been diagnosed with ADHD as
of 2011. The CDC has
named ADHD as one of the most common neurodevelopmental disorders among
children. ADHD often lasts into adulthood.

A combination of medication and behavioral therapy is often
used to treat ADHD. Both stimulant and nonstimulant medications may be used to
treat ADHD. While nonstimulants seem to have fewer side effects, stimulants are
the most widely used medication.

Vyvanse and Ritalin

Lisdexamfetamine dimesylate (brand name: Vyvanse) and
methylphenidate (brand name: Ritalin) are two types of stimulant drugs used to
treat ADHD symptoms like poor focus, impulse control, and hyperactivity. They
help treat these symptoms by increasing levels of chemical messengers such as
dopamine and norepinephrine in the brain. Each medication works in a slightly
different way and remains in the body for different amounts of time. These two
drugs can also have unique side effects.

Methylphenidate enters the body in its active form. Lisdexamfetamine
dimesylate is known as a prodrug. A prodrug enters the body in an inactive
form. The body then removes a substance called lysine to make lisdexamfetamine
dimesylate active. Because of this extra step, the effects of lisdexamfetamine
dimesylate can last up to 14 hours.

Dosage for Vyvanse vs. Ritalin

Lisdexamfetamine dimesylate (Vyvanse) should only be taken
once a day because its effects are long lasting. It should be taken in the
morning. You can take it with or without food. The typical dose is 30 mg. You
can either swallow the capsule whole or open the capsule and mix the contents
with food like yogurt, water, or orange juice.

Methylphenidate (Ritalin) is available in short-acting,
intermediate-acting, and long-acting (extended-release) forms. Short-acting
tablets are taken two or three times a day. Sustained-release (Ritalin SR) tablets
and extended-release (Ritalin LA) capsules are taken once a day.

Short-acting methylphenidate (Ritalin) may only last in the
body for four hours, while the longer-acting forms can last for up to eight hours.
Some types of the medication need to be taken without food. Others can be taken
with or without food. Doses range from 5 to 40 mg.

Side Effects of Each Drug

Both drugs are controlled substances. This means they have
the potential to be abused or used improperly. Because of the way the body
breaks down and uses lisdexamfetamine dimesylate (Vyvanse), it may be slightly
less likely to be abused than methylphenidate (Ritalin). People who have a
history of alcohol or drug dependence should talk to their doctor before taking
either of these drugs.

The two drugs can have similar side effects. The common side
effects for both drugs include:

  • appetite loss
  • digestive issues, including diarrhea, nausea, or
  • dizziness
  • dry mouth
  • mood disorders, such as anxiety, irritability,
    or nervousness
  • trouble sleeping
  • weight loss

Methylphenidate (Ritalin) has also been known to cause
headache and is more likely to cause increased heart rate and high blood
pressure. The effects of lisdexamfetamine dimesylate (Vyvanse) last longer than
immediate-release methylphenidate (Ritalin) and may be more stimulating. 

Both drugs can also have more serious adverse effects,

  • heart problems
  • psychotic or manic symptoms
  • reduced growth in children
  • seizures
  • tics

Who Shouldn’t Take These Medications

These medications are not right for everyone. You may not be
able to take either of these drugs if you have:

  • recently taken or are taking a monoamine oxidase
    inhibitor antidepressant medicine
  • heart or circulation problems
  • an allergy to the drug, or you’ve had a reaction
    to it in the past
  • a history of drug abuse

In addition, you should not take methylphenidate (Ritalin) if
you have the following conditions:

  • anxiety
  • glaucoma
  • Tourette syndrome

Which Drug Is Best for ADHD?

Both drugs treat ADHD symptoms like inattention,
hyperactivity, and impulsive behavior. Very little research has been done
comparing the two drugs directly. Studies that have
compared lisdexamfetamine dimesylate (Vyvanse) with other stimulant drugs have found
that it is about equally effective.

One advantage of lisdexamfetamine dimesylate (Vyvanse) is that
its effects last longer in the body than Ritalin. It may also be less likely to
be abused.

Your doctor can help you
decide which of these drugs is better for you. Once you do get a prescription,
it’s important to take the medicine exactly as prescribed.
