Singulair and x rays

50 year old male, prescribed Singulair 8 months ago to assist with allergy problems while taken allergy shot treatments. About 2 weeks ago started experiencing numbness/tingling in right foot, then both feet, the spreading up the body to above the waist. The best way to describe the sensation is a combination of the feeling you get when you hit your funny bone and the sensation when you sit or lay in a position that puts one of your limbs to sleep. Had all the blood work tests done at Dr. office to verify no other issues, all blood work is normal, Dr. suggested could be a neuorlogy problem and more tests will be necessary. Receive routine Chiropractic treatments and had him check everything, including new x-rays, nothing there. Read the side effects again for Singulair and realized that this numbness/tingling is just one of the symptoms I have had since starting this drug. The others being unusual weakness, tiredness, which I thought was just part of getting older and severe sinus inflammation, which I had thought was just related to my allergies. Have contacted my allergy doctor that put me on this and he said to stop taking Singulair to see if my side effects go away, since I am near the end of the time that he expected me to take them for anyway.
I will repost after a few weeks or as soon as the side effects go away.

I have two sons on Singulair, my three old was suspended today from pre-school for bad behavior. Screaming, biting, scratching, and hitting have been going on for the last few months. But worse the past two weeks. He has always been active and played like a boy, but he has been getting violent. We have tried positive reinforcement, praising good behavior both verbally and with rewards, I have tried time-out, being grounded, not being able to participate in activities, no t.v. and old fashioned butt spanking. All of this with no positive results. I am not looking for an excuse for my child's behavior, but could Singulair really be the cause of his aggression?

Hi, I am a mother of 6. They are 11,9,7,4,and twins 2 1/2. So nothing surprises me as far as kids. I have been through it all. My 7 year old had been taking singulair for allergies and ear pain, for over a year. Did my doctor once ask me about any of the side effect, NO!! This is not ok. My son suffered, decrease appetite, weakness, fatigue, mood swings, irritability, fears of being alone, scary dreams, anger, bone and joint pains. Before he was a loving kid (who had his moments)!!! I had no idea the singulair was causing all these destructive side effects. I just thought this is a phase he is going through, he will soon get over it. Finally I took him to his ped. and we did blood work and x rays. I told her something was wrong with him, he has not been himself over the past 6-8 months. This is one reason why I never suspected his singulair, it did not show up immediately. All of his test came back fine. I just happened to look at the side effects of this medicine. I almost died!!! Every single thing that this poor child has suffered from was on this list. Then more, I found this page and other mothers have had the same experience. I was just amazed that this has happened to so many. I was relieved that my son was normal. He has been off singulair for 6 days now (he doesn't know why I took him off it) . But you would not believe the change. It is AMAZING!!! In only 3 days, I started to see change in his anger. You would not ever in a life time believe that a medication can do this. I have been poisoning my son for a year. I think that Merck should take some of that 4.3 BILLION dollars and do some better research!!!! Concerned citizen you are right on. I have read many pages of this forum and I think you are doing a good job researching this. Maybe Merck should hire you as one of there "experienced personal". It just makes me seriously sick to see that the medical field is not seeing this problem!!!

It has been 18 days since my 9 year old daughter has taken Singulair. Our daughter had been taking Singulair for approximately 2 years. It was in the last year that we started to notice some behavior changes and mood swings that were so often unprovoked. We were somewhat concerned and thought like so many other parents that it was a phase. Then in December 2007 she came home from school with a tummy ache and had several episodes of vomiting. She seemed better the following day, but we took her to the pediatrician to be sure that this was a virus. The stomach pains continued, and then anxiety attacks began. Over the next month she began to wake up each day with stomach aches and we began more visits to doctors and more testing. She had abdominal X-rays, CT scan, mekel scan, GI consult and endoscopy. All were ok except she did have some small amounts of acid in her stomach. She was treated with Prevacid with really no significant changes. As weeks passed she missed more and more school, she just could not make it through the day. She had intense separation anxiety, and developed OCD about being sick again and vomiting, fears that she may stop breathing; fear of dying and the list goes on. She was refusing to ride the bus to school, and was having more and more panic attacks that would last for hours. We finally took her to a psychiatrist after we had done every test we could possibly do and all were normal. She woke up with the fear and anxiety, and fell asleep each night the same way. The doctor said she had "OCD" which she believes was triggered by the fear from vomiting. "This was the first time she had vomited since she was an infant.” She was treated with Lexapro, and Klonopin. The symptoms worsened over the next few days even with the new medications. After many calls to the doctor we were finally advised to have her admitted to a children’s psychiatric hospital for closer evaluation where higher doses of medications could be administered. She was there for 4 horrible days with slight improvements. Over the next few weeks the medication did begin to help some and she was able to make it through school each day as long as she was able to call me a few times a day for re-assurance. I thank God each day for her wonderful teacher and staff that have helped us through this. They all have known her for 3 years and knew this was just not her character at all and she was truly struggling. She was always known as "Smiley" to everyone because she always wears a grin. We began therapy with a psychologist as well and she has good and bad days. Then we heard the news about Singulair and I began to trace back other issues she had with focusing in 2nd grade and how things just seemed to progress from there. It all happened so gradually that I would never have put two & two together. She is showing improvements every day with personality, mood, attitude, fears, and the "OCD". She told me today that this was the best day ever!! I have made all the Doctor's involved aware of this information and the progress she has made in the last 2 1/2 weeks. Her doctor did cut her meds in half this week as well. Thanks to everyone that has posted their nightmares as well, and we will pray for you and for full recovery for all those that have suffered.

My almost 7 year old son was prescribed Singulair 3 years ago for severe asthma and allergies. It worked great--for a while. No hospitalizations, incidences of bi-lateral mucous plugs and pneumonia decreased, etc. I thought it was a miracle drug for him. This past summer/fall however, the nightmares, sleepless nights, multiple sinus infections, moodiness and mild anxiety, extreme hunger (he can now eat my 6'7" 260 lb. husband under the table and my son only weighs 52 lbs.), thirst, leg pains, reflux and very frequent complaints of stomach aches and nausea, etc. began. He was even admitted to our local Children's hospital in November for a severe upper respiratory infection that affected his asthma and blood oxygen levels and for the first time ever, did not respond to therapy. He was on oxygen for 3 days. Not realizing all this was likely due to Singulair, I took him to his ped. pulmonologist, pediatrician, ped. allergist, a ped. gasteroenterologist, and an ENT. None of our doctors suspected the Singulair--and I still have confidence that they are all good doctors. In December, he had surgery to cauterize the inferior turbinates in his nose and remove his adenoids to try to alleviate the sinus infections. At the same time, we had an upper G.I. series done to see if we could find what was causing all the stomach aches and reflux. The GI doctor found nothing. I am just sick to think that Singulair did all this to him, that we put him through surgery to try and "fix" the symptoms, and doctors and parents didn't know enough about the side effects of this drug to suspect it as a possible culprit!! I called our pulmonologist and pediatrician this morning to report my suspicions and took him off it. I sure hope his symptoms will improve.

My wife began taking Singulair April 2005 because of allergies (couging with some spitting) and by June when we returned to see the Dr. she was fine but her Dr. wanted to keep her on Singulair. The first of August she began having serious coughing and spitting (mostly at night) and it continues. The x-rays and ct scans show her lungs are okay. My question/concern is the Singulair ad on TV mentions a side effect of upper respitory infection and when I brought this up to the Dr. it was ignored. My wife does pretty well during the day but takes her Singulair at bedtime and either the laying down or the Singulair is causing her to wake up every 2 -3 hours coughing and spitting.

My (2) girls' father forwarded me this site. After reading all of these symptoms, I now realize why they are having the problems they are experiencing. My oldest (11) is on a 10mg and throughout the last school year has had so many headache phone calls to me to come pick her up along with stomach pains, nausea for no reason. Several trips to the doctor, stomach x-rays, etc. We were out of the medicine for the last week and remarkably she is just fine, sleeping all night, no headaches, etc.

My youngest (8) has had problems with the behavior and fatigue along with the weight gain. I truly believe all of these are from this medicine. I am taking them off for a full month trial to confirm my thinking.
