False negatives.
​
I just started taking Vyvanse 30mg last month. Signed all the contacts for regular drug testing and everything. I was a drug addict and have been sober for 6 and a half years; I've been honest with my doctor about everything too. I've been sober from everything, even weed and alcohol. The other day I went to my check up a month later and did the rapid urine tests, had no worries because I have nothing to hide and have no urges to misuse it or anything. I take it at the same time everyday right before work at 8am. The doctor comes in the room to tell me my results and I tested negative for everything. Not only my Vyvanse but my Lexapro I'm prescribed and take everyday as well. Needless to say I was very thrown off.
A little context here. I'm a woman who's 5'9 and 215lbs. I exercise regularly, cardio mainly and currently have been in a calorie deficit for 8 months, I've lost 45lbs so far. I sweat a lot after my workouts and drink plenty of water and have told my doctor in case that would interfere with the negative drug tests. I was very embarrassed because since I use to be an addict, I can see why they'd be concerned. I've always been honest with them and told them I take it everyday; my husband even locks it in a safe and gives me one in the morning because of my history for safe measure which my doctors encourage. Thankfully my doctor does believe me and thinks it's an issue with the rapid urine testing there for they're going to do more complex tests which I am more than willing to do. I told them they can test me multiple times for blood, urine, hair if needed because I have nothing to hide.
This medication has worked great for me, I am more calm and collected and can stay focused. It doesn't effect my appetite or sleep either like I thought it would which is good. I'm very relieved the doctor is working with me, but has anyone else gone through this? I talked with my parents about this and they're just as confused. My cousin's who's on the same meds tested positive for her regular drug screenings too, so this is just super weird to me and I'm very proud and devoted to my sobriety. This is also the first time I've ever been tested for meds before because this is my first time being prescribed an ADHD medication.
