What is Dyanavel XR?

Dyanavel XR oral suspension (amphetamine) is a central nervous system stimulant that affects chemicals in the brain and nerves that contribute to hyperactivity and impulse control.

Dyanavel XR is available as extended-release tablets and extended-release oral suspension for the treatment of attention deficit hyperactivity disorder (ADHD) in people 6 years and older.

It is not known if Dyanavel XR is safe and effective in children under 6 years of age.


Dyanavel XR may be habit-forming. Tell your doctor if you have had problems with drug or alcohol abuse.

Stimulants have caused stroke, heart attack, and sudden death in people with high blood pressure, heart disease, or a heart defect.

Do not use Dyanavel XR if you have used an MAO inhibitor in the past 14 days, such as isocarboxazid, linezolid, methylene blue injection, phenelzine, tranylcypromine, and others.

Dyanavel XR may cause new or worsening psychosis (unusual thoughts or behavior), especially if you have a history of depression, mental illness, or bipolar disorder.

You may have blood circulation problems that can cause numbness, pain, or discoloration in your fingers or toes.

Call your doctor right away if you have: signs of heart problems - chest pain, feeling light-headed or short of breath; signs of psychosis - paranoia, aggression, new behavior problems, seeing or hearing things that are not real; signs of circulation problems - unexplained wounds on your fingers or toes.

Before taking this medicine

You should not use Dyanavel XR if you are allergic to amphetamine or any stimulant medicine, or if you have used an MAO inhibitor in the past 14 days, such as isocarboxazid, linezolid, methylene blue injection, phenelzine, or tranylcypromine.

  • chest pain or breathing problems caused by heart disease;

  • hardening of the arteries;

  • if you are agitated.

Tell your doctor if you also take opioid medicine, herbal products, or medicine for depression, mental illness, Parkinson's disease, migraine headaches, serious infections, or prevention of nausea and vomiting. An interaction with amphetamine could cause a serious condition called serotonin syndrome.

Stimulants have caused stroke, heart attack, and sudden death in certain people. Tell your doctor if you have:

  • seizures or epilepsy;

  • an abnormal brain wave test (EEG);

Popular FAQ

The main difference between Adderall and Vyvanse is that Adderall is a mixture of four different kinds of amphetamine salts (one of which is dextroamphetamine) while Vyvanse only contains one type of amphetamine salt, called lisdexamfetamine. Lisdexamfetamine gets converted into dexamphetamine once it is in the body. One advantage of Vyvanse is that it may be less likely to be abused; however, there is no generic form available so it is more costly than Adderall. Because both drugs contain amphetamines, they work in a similar way. Studies have shown that Vyvanse is just as effective as Adderall, and side effects, including the risk of dependence, are similar.
