Vyvanse (generic name: lisdexamfetamine) is a medication used to manage attention deficit hyperactivity disorder (ADHD). The medication belongs to the class of drugs called central nervous system stimulants. It changes the levels of neurotransmitters (chemicals) in your brain, and decreases your inattentiveness and hyperactivity. Typically, you will take 30mg of Vyvanse daily or as your doctor recommends, says the National Library of Medicine.
Common Side Effects
According to MedlinePlus, Vyvanse can cause a headache, stomach pain, dry mouth, nausea and diarrhea. It can cause vomiting, a poor appetite, weight loss, fever, diaphoresis (sweating), dizziness and drowsiness. Vyvanse's other common side effects include tremors, nervousness and a fever. In a four-week clinical trial study of 358 patients taking Vyvanse, the National Library of Medicine says that 26 percent had dry mouth, 7 percent had nausea and diarrhea, 4 percent experienced nervousness and 27 percent developed a poor appetite.
Serious Side Effects
Drugs.com says that Vyvanse's harmful side effects include palpitations (pounding heartbeat), tachycardia (fast heartbeat), arrythmias (irregular heartbeat) and tremors. It can cause hallucinations, strange behavior, restlessness, tremors and hypotension (low blood pressure). Hypotension can result in lightheadedness and subsequent fainting. Vyvanse can cause severe hypertension (high blood pressure) and can result in an intense headache, confusion, chest pain, blurry vision, convulsions and trouble breathing. Go to your local hospital right away, as these symptoms can be fatal.
