For ADHD "I have been taking Qelbree for a week and a half, and I have experienced bipolar symptoms, constant anxiety attacks, random episodes of crying, constant and persistent suicidal thoughts, constant feelings of nausea, and extreme irritability. I also have insomnia. None of these symptoms occurred before I started on Qelbree. Please don’t take this. It turned my life into a living hell."

For ADHD "My son, who is now 12 and on the spectrum, was on this medication for a little over a year. I noticed he was extremely angry and irritable, more so in the morning. He was on 200 mg. He’s on several other medications that treat other issues. His doctor kept increasing those meds despite me saying that I thought the Qelbree was actually the problem. I took it upon myself to wean him off the Qelbree. Day 1 - his teacher said he had an amazing day. Day 2 - 5, his days were even better. His teacher said the difference was like night and day. I would never recommend Qelbree to others because I think the risk of mood changes, anger, and irritability only increases. My son’s anger was so bad that he was hitting others and throwing objects. He is now so much better now that he is off Qelbree. Believe the 1-star reviews!"

For ADHD "My son has comorbid anxiety and ADHD. When we finally saw, after a year+ (granted, a Covid year, with all the variables and extra stressors), that first Concerta and then Vyvanse were very helpful at school but increased my son's anxiety and agitation to the point of physical aggression and verbal abuse, we took him off stimulants. We were so excited to try Qelbree. But by day three, we had to stop, as it made him physically and verbally violent. We almost called 911 at one point... and he is only 9 years old. Some of this likely has to do with him going off Cymbalta in order to take Qelbree because they contraindicate. We'd hoped that since Qelbree is an SNRI, it might help his anxiety, but we didn't expect Qelbree to make things (so much) worse. We got no advice from our psychiatrist re: if it would subside, so we decided to quit; everyone in our home (two parents and two siblings) was traumatized. Qelbree may not be a good fit for comorbid anxiety and ADHD... sadly, nothing is."

For ADHD "My 14-year-old son tried Qelbree, and it was a nightmare. He was tired, irritable, and constipated. He developed a dry cough, dry mouth, and a red rash on his face, as well as nosebleeds. It also did not help his ADHD symptoms."
