Allergic Rhinitis
"I wish I had reported this to the FDA when it happened. I don&#039;t know how helpful my account of the side effects from many years ago would be now. However, I would like to share this somewhere, as what I experienced is not verified as a side effect but possibly suspected--- I don&#039;t want anyone to go through what I went through and not suspect this medication to be the culprit. After taking one dose of Singular in the evening, the next day, I experienced suicidal thoughts, severe anxiety, and a feeling as if I were being separated from my body (if that makes sense). I have no history of such problems, never took Singular again, and never experienced what I described again."
