SINGULAIR  (MONTELUKAST SODIUM):  Montelukast is used regularly to prevent the wheezing and shortness of breath caused by asthma and decrease the number of asthma attacks. Montelukast is also used before exercise to prevent breathing problems during exercise (bronchospasm). This medication can help decrease the number of times you need to use your rescue inhaler. This medication is also used to relieve symptoms of hay fever and allergic rhinitis (such as sneezing, stuffy/runny/itchy nose). This medication does not work right away and should not be used to treat sudden asthma attacks or other breathing problems. This drug works by blocking certain natural substances (leukotrienes) that may cause or worsen asthma and allergies. It helps make breathing easier by reducing swelling (inflammation) in the airways.   FDA Approval Date: 1998-02-20 (Sources: U.S. Centers for Medicare Services, FDA)

 1  asthma like symptoms My twin boys were 18 months when they took this medicine and they BOTH began to have mood swings, one alot more than the other. We noticed it begin 2 days after we started the medicine and within 2 weeks our one son was having major fits 4-5 times a day for about 15 minutes each. You could tell he was unable to control them. It worked great for there cough at night and wheezing but the behavior change was not worth it. After we stopped the med we have not seen those behaviors. M 2 3 weeks

 3  Asthma, irregular sinus problems. Depression, anxiety. Taking singulair did help my breathing, but caused me to become extremely moodly, depressed and anxious. Not just the odd bad day which everyone experiences, but full blown depression. I have tried being on and off the medication to see the difference a few times, and being off it has helped me relax significantly. Not worth taking for me - it didn't do anything my puffers couldn't. M 19 5 months

 1  asthma panic attacks, depression, irrational and extreme anger, mood swings, increased bleeding during periods, tremors, derealization, anxiety I wouldn't recommend this drug to anyone and it should be taken off the market, or Dr's should be strongly cautioned to try everything else first before prescribing it.

 3  Asthmatic Symptoms My son is 2y 11m and was prescribed Singulair for Asthmatic symptoms after 3 months of continuous illness ~Within 5 days his breathing improved dramatically and i was impressed with the results, however after 10 days his skin on his arms and legs became like sand paper and then he became hyperactive at night He is a fantastic sleeper having gone through the night from 4 months He wakes in the night banging the cot, screaming and wanting to run around, which can last for hours He seems unable to hear me and falls asleep exhausted only to sit bolt upright again minutes later I hardly recognise him Usually a passive child he bites, pinches and kicks He has Downs Syndrome and many medical problems for which he has other medication so i dont know if this is only the Singulair or a combination problem Once i read the side-effects leaflet i felt sure this drug was a cause He sees the Pead in a week so i have halved the dose until then....

 1  Allergy related asthma Depression, fatigue, anhedonia. Have stopped for 2 days now and am feeling better each day. Also seemed to affect my 2 year old son who I am still breastfeeding but that might be subjective based on my general grumpiness while taking it. Seemed to make him more apt to cry over little things and to affect his sleep? I will have to wait a little longer as I have only stopped for 2 days so far. F 36 10 days

 3  Asthma I am glad I came across this website. I am generally a happy go lucky person. In the past year or so I have experienced wild mood swings, anger issues and sometimes depression. I am scared to go off because it actually works and helps control my asthma. I am 31 years old and play a sport with need for lots of endurance. I will be speaking to my dr. about other options. Geez... Glad its the meds and I am not this mean person:) M 31 7 years

 1  Asthma Anxiety, racing heart, breathlessness, leg spasms I take Singulair only as needed, and had recenlty taken it after not having taken it in a few months. All day I was short of breath. When I went to lay down to sleep that night, my heart rate skyrocketed. We went to the ER and my resting heart-rate was 180. I could barely talk and my legs were convlusing. The Dr said it was a caffiene induced anxiety attack. I didn't have caffiene or anything for 4 days. On the 4th day I took my singulair and the same thing happened when I laid down for bed that night. These attacks are scary. I was concrned I would go into cardiac arrest. I have never been so scared. My allergist discontinued my use if Singulair and said that anxiety attacks is a very rare side effect. Be warned, it is not inside your head, it is an actual reaction to the chemicals. F 26 2.5 years

 1  allergies Internal tremor throughout my body, leg pain and cramps, tingling in extremities ,shooting electrical pains throughout body, numbness in extremities, my skin and insides feel as if they're burning, heart palpitations and chest pain, anxiety, severe headache, fatigue. Update 12/19/10 Still having the internal trembling, however, it's not as bsd as it was, yet still bad enough to interrupt my life and my sleep. I'm still suffering from fatigue and a lack of energy. I still have some tingling now and again in my hands and feet. I wish everyone who is suffering from this medication all the best and I hope this serves as a warning to those considering taking it.

Patient History
 4  Asthma My daughter has been on the medication to treat her asthma for quite some time. I never thought much about the side effects because most drugs come with side effects and you can't get too hung up on every detail, especially when the benefit of taking the pill is clearly positive. In the past several years, I have noticed my daughter's propensity to anger very quickly and when she does, it is completely out of control. She unleashes on me and her brother, in particular, and she has told me that her brain just can't control it. I started wondering about why this was so prevalent with her and whether there is a connection between her taking Singulair and this behavior. Also, for the past several years, she has a facial tic that comes and goes. While this is not uncommon in children, she seems to get it every year around the same time -- when the weather starts to get cold. I am now starting to wonder if there is a connection between her Singulair intake and her facial tics. Based on F 8 5 years

 1  asthma Within one hour of taking this med. I began experiencing hot flashes, feeling faint, sweating palms and tingling in arms and legs (almost like when you take a high dose of Niacin). This sensation lasted on and off for about 26 hours (terrible experience). I could not sleep the entire night. Would have thought I was having an anxiety attack except for the fact that I could breath great! Not worth it though. I will never take this again. F 43 1 days

 1  Severe allergies Anxiety,anger,depression,insomnia,weight loss,palpitations,decreased energy. Having suffered from severe sinusitis due to allergies for 30 years, having used cortisone sprays, pseudo ephedrine with little effect I discovered Singular and researching that it blocked receptor that causes allergic reactions I thought I would give it a try. Yes it was great for allergies but the side effects were dangerous. I actually thought I was going to end up in a mental hospital. I do have a very busy schedule, but I was unable to cope with anything. M 54 30 days

 5  Asthma Mood swings, serious emotional side effects Singulair has really bad emotion side effects but it has saved my life. I started taking it when it first came on the market for asthma. Before this drug I was very sick and never slept one night without an attack. 12 years later and I sleep, every night. I only wish it was less expensive( 230ish a month without insurance...ouch).

 1  allergy symptoms - cough/congestion Temper tantrums, crying over smallest things, agressive, pushing, bad dreams, potty accidents, generally out of sorts My 3 yr old son was prescribed this medication in lieu of Zyrtec while awaiting allergy testing. We go to the doctor tomorrow for the tests. I stopped giving him Singulair today. I have seen a DRAMATIC change in his mood. He is aggressive towards me and his sisters and father. He does not want to participate in even the mundane activities of the day like taking his sister to school... throwing himself on the ground, crying, hitting. He never did this before. He has also had 4 pee accidents in two days. This is a first. He has not had an accident since he was potty trained 6 months ago. No other changes have taken place in our family, no other trauma I can point to. He suddenly just felt "bad". He doesn't know why when you ask him. I had some reservations before going on the medicine when I read the indications on the package. I asked his current Pediatrician and his former Ped. and both felt it as safe as their children were on it. This is just too coincidental for it to be a behavioral problem that showed up out of the blue two days after starting this medication. Thank you for the posts. It just confirmed "that little voice inside" that said something was wrong with this medicine. M 3 5 days

 1  Asthma My daughter, now 6, has been on singulair since she was like a year old. She has always seemed sad and worried about everything and at times had the "glazed over look". Her father and I divorced when she was very young and it was not the nicest divorce. We always chalked up her "issues" with the divorce and spent lots of money on therapists who couldn't find anything wrong or abnormal. Recently, we uped her dosage due to her age and her asthma still not being under control. She startd having some even crazier behavior problems! She was more angry and at times, out of control. She was anxious all the time to the point the school called to talk about it. She seemed more sad than usual and sometimes out of it! She complained of a tummy ache all the time. She was just a different kid, worse than what we had grown "accustomed to". I heard a story on TV about Singulair and the side effects. I started doing research on it and immediately called the specialist who M 6 5 years
