My son has been taking Singular for a few years for mild asthma and recently in the past few months all of the sudden he has been having a hard time falling asleep,anxiety at bedtime taking hours to get to sleep with me having to stay in the room. We took him to his pediatrician who ran blood tests and referred me to a sleep specialist who suggested he may have OCD or Anxiety. I just thought it was just something that would pass after 4 months it still has not passed. I am removing him from Singular TODAY. After all these visits with these doctors who knew he was on the medication and never said anything to me about possible side effects . I cant believe it took an article my husband saw in the paper for this to come to my attention.
