Hi, i was just informed that my friend is in the hospital because she couldn t breath. I was also told that prior to the breathing problems, she took 220mg of Vyvanse within a 24-hour period.She s been prescribed 30mg once or twice a day for a couple months, though hasn t been taking it consistently. She s about 5 5 , and between 200 and 215 pounds. I need to know how likely it is that the 220mg of Vyvanse that she took lead to an overdose causing her breathing problems.
Thanks for your question on Chat Doctor. I can understand your concern. Vyvanse is central nervous system (CNS - brain) stimulant, not suppressor. So her breathing difficulty is not due to this Chat Doctor.  She is very obese. So possibility of sleep apnea is more likely in her case. And this (sleep apnea) can cause breathing problems. So get done sleep study to rule out sleep apnea. Hope I have solved your query. I will be happy to help you further. Wishing good health to your friend. Thanks.
