Pediatric patient symptoms and conditions

Our 4 year-old son was prescribed Singular 4mg tabs approximately 1 year ago and I started to notice a dramatic change in our son's behavior almost immediately. He progressively became more aggressive, suffered from very strange/intense dreams, cried easily, temper tantrums and became very physically aggressive. He also seemed to suffer from dramatic mood swings. He even tried to choke me several times. THIS IS NOT OUR SON!!! We sought out Professional Therapy thinking that it was emotional ties to his father being in Iraq. It was only after I (Pharmacy Technician), decided to investigate the drugs he was taking for allergies a bit further. I felt this "maternal instinct" if you will to discuss termination of the Singular with his doctor. I approach it from a decrease in meds for him at the time. He was taking Zyrtec, Singular and Nasonex. I tapered his dose for a period of two weeks. (This was my decision, please follow DR or Pharmacist recommendations for stopping this drug). We noticed a marked improvement in mood swings, sleeping patterns, attitude, house rule compliance. We agree that his therapy was responsible for some of these changes but it was only after we dc'd the Singular that we noticed a change in his overall being. He is now a more stable and friendly 4yr. old.
Trust your instincts as a parent. All drugs carry side effects and you must be well informed as a patient and a parent. Consider the side effects against the usage for the drug. This is our experience with the drug Singular and our Pediatric patient. We will not put our son back on this medication.

My 5 year old son was put on for very mild asthma before xmas. After he returned to school, the teacher noticed he was not listening, difficulty attending, talking nonstop ( normally quiet), and repeating the same questions. At home, we noticed complaints of tummy aches, after 2 weeks very loose stools, irritability, extreme difficulty attending to any task, disorientation, rolling around on the floor, tic disorder; he started flipping his head side to side as if he's checking for something, and poor sleep (3-4 times awakening) esp. w. vivid nightmares, eg. crying because his snowman was melting and dying and dry nasal passages w/ bleeding sometimes. I notified the asthma/allergy doc. that we were going to discontinue. It has been a week now and his stools have formed better, not complaining of tummy aches, but attention/concentration still an issue as are tic movements; also came down w/ sinus infection so perhaps being sick is attenuating these symptoms. I hope he can get back into his zone. We are worried.
