Adderall and Vyvanse are prescription psychostimulant drugs used to treat attention deficit hyperactivity disorder (ADHD). While Adderall is sometimes the more effective of the two, Vyvanse is considered less addictive. Adderall is a combination of dextroamphetamine and amphetamine; in Vyvanse, the active ingredient is lisdexamfetamine.
Both Adderall and Vyvanse increase the amount of dopamine and norepinephrine between synapses in the brain, which is useful for several medical conditions.
Adderall, which is used to treat ADHD and narcolepsy, is also sometimes prescribed for depression, obesity, and sleep cycle disorders. Vyvanse is used to treat ADHD in individuals ages 6 and older. Doctors are also researching its effectiveness at treating depression, schizophrenia, excessive daytime sleepiness, and binge-eating disorders. While more research is necessary, there is some evidence that both drugs may prove useful as smoking cessation aids.
Numerous studies have been carried out on Adderall and Vyvanse regarding their efficacy and safety. Compared to placebo, children are much more likely to remain focused in school when taking these drugs.
Overall, Adderall and Vyvanse are similarly effective at treating ADHD in children and adults and are generally well-tolerated, even up to daily doses of 70 mg. However, Vyvanse has so far been found to be less addictive.
Adderall is available in either tablet or extended-release capsule form. The tablets should be taken 2-3 times every day at 4-6 hour intervals. For individuals aged 6 or over, dosage begins with 5 mg once or twice daily and can be increased by increments of 5 mg every week. The dose rarely exceeds 30 mg. The capsule is taken once a day in the morning and should be swallowed whole, or opened and the contents sprinkled on apple sauce. Adults taking the capsule usually receive a dosage of 20 mg a day, while children and adolescents usually start with 10 mg a day before the dosage is increased.
Vyvanse is a single capsule taken once in the morning, with or without food. It can either be swallowed whole or opened and sprinkled into water. The recommended starting dose is 30 mg a day, but this may be increased by increments of 10 mg or 20 mg a week up to a maximum of 70 mg a day.
Adderall may cause a temporary decrease in growth rate but does not affect eventual adult height. It may decrease appetite, leading to weight loss. It can cause insomnia, headaches, increased muscle tension, irritability, and anxiety, as well as an increased risk of cardiac problems.
A 2010 study has found that treatment with Vyvanse led to statistically significant reduction in expected height, weight and BMI. It may cause discomfort, erectile dysfunction, dizziness, restlessness, nausea, dry mouth, anxiety, diarrhea, vomiting, headache, insomnia, irritability, upper abnominal pain, and a loss of appetite.
Adderall should not be taken during early pregnancy or within two weeks of taking any MAOI medication. It causes a risk of serotonin syndrome when combined with SSRIs like Prozac, Zoloft or Lexapro.
Vyvanse also should not be taken during pregnancy or within two weeks of taking any MAOI medication.
Adderall is a habit-forming drug. When an individual stops taking Adderall, they may experience extreme fatigue, insomnia, irritability and mental depression.
Vyvanse was designed to be less addictive than Adderall, but still has withdrawal side effects if abused, including exhaustion, depression, mood swings, heart irregularities and psychosis.
Adderall and Vyvanse are both often used by college students to increase concentration. Adderall is more commonly used than Vyvanse.
Selling or giving away Adderall or Vyvanse without a prescription is a felony.
According to a 2013 drug trend report, Adderall is, by far, the most popular of the stimulant drugs. However, compared to Adderall, which was approved by the FDA in 1996, Vyvanse, approved in 2008, has gained its popularity very rapidly.
