My six year old daughter started taking Singulair for winter allergies about 1 year ago. After a couple of months she woke up seeing floating bubbles. These were very real hallucinations. We were back and forth with specialists for about 6 months. After she was taken off of the Singulair in the spring, the hallucinations gradually went away. We did not notice the connection. She has been back on the Singulair for one week, and last night she woke up seeing ants crawling on the bed and on her. I am stopping the medication and contacting the doctor. I would really like to know if anyone else has had similar problems.
