Chronic runny nose symptoms and conditions

My daughter, just turned 3, was put on Singulair this past January for allergies. She had chronic runny nose, sinusitis, coughing, often leading to infections. The allergist put her on Singulair combined with Hydroxyzine every night. Now that I have read these postings, I recall that we had one really disturbing episode with her, although I can't now recall exactly how long after starting the drugs. Like some others have described, she woke in the night, seemingly terrified and at the same time in extreme pain. We could not find any way to soothe her or relieve her pain - she simply fought and flipped around, alternately reaching for us and kicking us away while screaming and crying and writhing on the bed. After a time, maybe half an hour, it seemed to just pass and she finally went back to sleep. But then we endured a couple of months of repeated wakings at night, sometimes when she was restless for an hour or more, sometimes upset. She might wake 3, 4, or 5 times in one night.

Lately I have become concerned about her increasingly aggressive behavior towards us, but recently towards others. And I am also very concerned about her physical growth. She is 41" and over 40 pounds and turned 3 a week ago. I am now buying her size 5T clothes. I have finally gotten proactive (why did I wait??!) and consulted with her ped., who has agreed that we should screen her for anything we can. My daughter has been diagnosed with developmental delays (pre-Singulair) and is in a preschool with similar kids. We have been dealing with behavior issues for the last year, and I am astounded that an allergist would put her on Singulair with the current controversy about it's side effects. I took her off it immediately as soon as I found out there were negative reports - thankfully our experience has not been as extreme as many others. But I feel ill at what could have happened! I am now praying that she has not suffered any irreversible damage...

Bless all of you in your struggles.

100mg 2x daily for complex partial siezures.. Initially thought this was great after dealing with dilantin and feeling like a tired zombie. The only side effect I had was a chronic runny nose. I then started having low back pain, then nearly unbearable muscle spasms down the back of my legs. It was so bad I was setting alarms so I could take ibuprophen round the clock. I began having stomach issues from the ibuprophen, so I scaled back to only taking it in the am. Muscle spasms are now tolerable, but I've developed a new issue - I'm often dizzy and have random blurred vision. I waited 6 months to get my license back (after one minor siezure). Now I don't drive because of the side effects. I don't know whether cutting back the dose of lamictal would help, but I intend to ask.

Upon the 1st dose ( 1 tbs), before breakfast I experienced no side effects and an immediate suspension of a chronic runny nose.
