What is Dyanavel XR?
Dyanavel XR is an extended-release oral suspension used to treat attention deficit hyperactivity disorder (ADHD).
Dyanavel XR may be habit-forming, and amphetamine is a drug of abuse. 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, rasagiline, selegiline, or tranylcypromine.
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 any stimulant medicine, or if you have:
moderate to severe high blood pressure;
severe anxiety, tension, or agitation (stimulant medicine can make these symptoms worse); or

Some medicines can interact with amphetamine and cause a serious condition called serotonin syndrome. Be sure your doctor knows if you also take stimulant medicine, opioid medicine, herbal products, or medicine for depression, mental illness, Parkinson's disease, migraine headaches, serious infections, or prevention of nausea and vomiting. These medicines may interact with amphetamine and 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:
heart problems or a congenital heart defect;
high blood pressure; or
a family history of heart disease or sudden death.
To make sure Dyanavel XR is safe for you, tell your doctor if you or anyone in your family has ever had:
