On April 24, 2008, the US Food and Drug Administration approved Lisdexamfetamine – known as Vyvanse – to be used for adult ADD and ADHD. Prior to this announcement, the medicine was just approved for use in children aged 6-12.
Although people often think of Attention Deficit Hyperactivity Disorder as just a disorder of childhood – it often carries on into adult life – and studies have shown that over 4% of US adults have ADD or ADHD.
Despite the fact that Vyvanse has just received approval for use in adults – it has been used by some doctors previously, through ‘off label usage’ (see my previous article on this: Vyvanse in Adults).
The study which led to the approval included 414 adults, aged 18-55 years old. Over 4 weeks, they were tried on Vyvanse or placebo. Generally, the adults noted significant improvement within 1 week of starting the medicine. All doses used (i.e. 30 mg, 50 mg and 70 mg) were all found to be helpful.
The most common side effects experienced by the adults in the study with Vyvanse were: decreased appetite, difficulty falling asleep, and dry mouth.

Does this mean that you should try Vyvanse if you are an adult with ADD or ADHD?
It just means that this is a good treatment option, and that the research has now been done to prove that it is effective for use in adults with ADD and ADHD.
It is best to talk to your doctor about your medication (and non-medication) treatment options.
As I have previously mentioned, as a doctor working in Canada, I have not been able to prescribe Vyvanse, because it has not yet come to Canada.
So, I have asked readers of this blog if Vyvanse works. To read over 275 responses, click here: Does Vyvanse Work?
