Paediatrician symptoms and conditions

My son was put onto 4mg Singulair when he was three years old. He is now six years old. For the past three years he has been a very quiet child, to the point that people commented on how shy and withdrawn he was. He never wanted to go anywhere or do anything. His favorite activity was lying on the couch watching tv. He was always thirsty, frequently went to the toilet,often complained of a sore stomach & had several bowel movements every day, did not sleep well at night, was often grumpy, could not concentrate for very long, was frequently ill with cold-like symptoms and did not really like you to touch/hug him. At the beginning of the year he was diagnosed by an occupational therapist as having low muscle tone. In March of this year, his pediatrician increased his singulair to 5mg. He began having terrible pains in his legs, to the point that he would cry and be unable to walk to the toilet at night. I took him to my GP who did every blood test under the sun and x rays of his pelvis and legs. He could find nothing wrong. The only thing that had changed was the increase in Singulair. I had a look on the internet and found this website. I immediately decreased his dose to 1/2 a tablet for a week and then 1/4 tablet for a week before taking him completely off it. Within a few days our whole family and his teacher and therapist noticed a huge change in his personality! He talks all the time now, he laughs a lot, he loves playing outside and has lots of energy. He teacher says he is much more receptive at school. His occupational therapist says his muscle tone has improved. He has not had one single leg pain since coming off the medication. He is sleeping well at night, his stomach is never sore and he has not been sick at all. Not even one little sniffle!! Best of all he is a normal, affectionate little boy. I feel very angry with the manufacturers of Singulair and with his pediatrician, it feels as though my son has lost three years of being a child. He felt terrible all the time and I had no idea! I have told everyone I know who has a child on singulair to look at the side effects.

Be aware that "Brick Red Stools" in children can suggest a bleed from Mackel's diverticulum and hence must be referred to a paediatrician. Mackel's diverticulum is a congenital condition. The bleeding usually settles on its own but very rarely the child can become severely anaemic and may need a blood transfusion. Surgical intervention also is very rare.

My 8yo son has been on Singulair for his asthma for about 2 weeks and he has complained of a 'sick tummy' regularly, ending up in tears because he can't do things. We have had a long run of this, perhaps due to the 8 lots of penicillin for tonsillitis, and some tummy bugs going around the schools I work in. The doctor has been suggesting irritable bowel syndrome so we didn't think of the Singulair side effects until it has got so bad that he is not going to school.He has been unusually clingy and almost paranoid about small things that don't usually worry him over the past couple of weeks. We were trying these tablets as he has been on steroid based preventer since he was 3 and we wanted to get him off the cortisone stuff. After reading here he is off the Singulair today and we will report the side effects to the paediatrician.

I am a paediatrician in private practice. I recently put an 8yr old boy with moderte to severe asthma on singulair. He is also epileptic and is on lamictin. After starting the singulair he experienced intense headaches, dizziness and blurred vision.
The headches were associated with vomiting. I have subsequently stopped the singulair but was really surprised by these side effects. Could it be related to his epilepsy? I have been using singulair for many years but this is the first case that I have seen with these side effects.

I am a mother of a 2.5yr old who has been on singulair for 6mths due to bouts of pneumonia and constant breathing problems. I have been trying to pin point what is causing him to suffer these bouts and if it could have anything to do with behaviour changes and I am stunned to read some of these side effects. My lovable boy has turned into a right monster, he doesn't sleep well at night, he screams for no reason, inflicts pain on his siblings, spits and hits me, he seems on edge and he even looks like death warmed up!!, He is very pale and his face is drawn. i am at my wits end with his constant whinging and crying. I have not told my paediatrician this information as I honestly thought that he was going through the terrible two stage in a big way!!, But now I think that maybe Singulair could be the cause of his personality change. I shall follow up with paediatrician ASAP. If anyone can shine a light on my problems please contact me.
