Please, if you have time, file a report with the FDA. The more reports they get the better! Good luck!

That is exactly how my daughter was. It was like a switch went off and she would go into raging tantrums. Thank goodness after 13 days of being off her tantrums are gone. The last tantrum was 9 days ago and it was because she couldn't walk barefoot down the street to her friend's house. She is 10 years old mind you. Very out of character. She had been having mood swings but then out of the blue she started having these raging tantrums frequently. Every day she seems to be getting better. Hopefully no permanent damage has been done to any of our children. Have you filed an online complaint with the FDA?

My daughter is 3 and she has been taking Singulair for about 3 weeks now. She is a very sweet, loving little girl. My husband and I started noticing that she complained of stomach aches and leg aches. Then she started wetting her bed a couple times a week, and was refusing to go potty before she laid down. I thought that was really odd, she has never had any accidents before. Then she started acting violent toward me and my husband :hitting, kicking screaming, biting, pinching, breaking her toys, tearing her room apart! She is only 3 !!!! Today she tore her room apart, smashed her keyboard, and so I removed all the toys and dolls etc.. from her room. Then she got even worse, running through the house screaming and throwing her self on the floor and banging her head on the ground. I did not know what to do so I grabbed my camera and tried to video tape her behavior, I sat the camera on the dresser to record her as I was trying to comfort her and she attacked me, ran over to the camera and threw it against the wall! I was shocked. I called the pharmacist and he told me to discontinue the medication and that it can cause violent behavior in children. I am so angry for not knowing that this could happen to my beautiful little princess. I am truly outraged about all this, I am a bit relieved to have found these stories posted, so now I know that it is that medicine not her. THANK YOU!!!!!
