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)

 2  Asthma Severe headaches lasting two or more days. Singulair definitely cleared up my asthma symptoms. I did not need an inhaler during the time I was taking it. However, the severe headaches forced me to discontinue taking it and I am now back on Ventolin on a daily basis. M 53 6 months

 2  asthma allergies increasing numbness in hands and feet, fasting blood sugar increase of 23 points into the pre-diabetic range [no family history], blood pressure increase, anxiety , slurred speech, headache, preoccupation with health and death, sadness Initially thrilled to be able to breathe through my nose, totally allergy free in high season, ebullient with relief from allergy/asthma symptoms, proclaimed Singulair as the med that changed my life. Now know that the change has been for the worse [except respiratorily], and am stopping it tonight. F 53 3 days

 1  seasonal allergies Severe drowsiness, almost falling asleep while driving. Mood shifts, anomie, lack of enthusiasm about life, laziness. It was very hard to attribute this to the drug because it takes a while to start, but it alleviates quickly when drug is stopped. No noticeable relief of allergies: possibly got a bit worse. Stopped taking it a week before the news reports started. I do not think this drug should be widely prescribed. I would never give it to a child too young to express themselves clearly, would monitor carefully for behavior changes over a time frame of weeks, and would avoid starting at the same time as other drugs. None for me thanks. M 53 1 years

 1  Allergy problems, sinus I am a glass half full type of person. Within 36 hours of taking this medication I was having very depressing thoughts, by the end of the second day I felt like I was having an out of body, numbness everywhere... terrible side effects. Found this link, read other comments. Stopped about 72 hours ago and returning to normal quickly. It did clear nasal passages but need another solution, the side effects are just too great.

 1  pediatric asthma My eight year old daughter - previously a happy, well adjusted girl - became depressed, attempted self mutilation and entertained thoughts of suicide. After taking Singulair myself, I understand what my daughter went through. I wake up every morning with very dark thoughts. It is not depression, just misery. What my daughter went through is shocking. DO NOT ALLOW YOUR CHILDREN TO TAKE SINGULAIR OR ADVAIR. It is not worth the price... F 53 8 months

 1  Asthma Nightmares, insomnia, depression, weight gain, suicidal thoughts, joint pain. I was perfectly healthy prior to taking this drug. Doc noticed I had a little wheeze and prescribed Singulair. I began to have the dreams, insomnia and depression after the first few days. I told the Doc and he said to go off for 4 days & try again. I started again after 5 days and the insomnia went away but the depression got worse and I began getting pain in my joints. I was always starving and gained weight.Once I began with the suicidal thoughts, that was it. I stopped taking it along with a steroid inhaler I was given. I was on no other drugs. Things got much worse for at least 3 weeks (sores in my nose, unable to breathe, coughing, rashes, swollen painful joints, stomach pain, sore throat)I had blood tests that came back positive for RA. Now, 5 weeks later, it is all slowly getting better. I would never, ever give this to a child and I would never take it again. F 53 20 days

 1  Severe Allergies & Ear fullness SEVERE TOOTH PAIN/DECAY, GUM ABCESSES, JOINT PAIN, WAKING UP FEELING HUNG OVER/EXHAUSTION I had been taking the generic form called Montelukast. Toward the end of 2018, my pharmacy informed me that they were using a different maker called "CAMBER" & to let them know how it was was working out. They are pink hexagon shaped tablets. After over a month later, I noticed that my molars were hurting. Started out as a deep ache, then turned into swollen gums at the base of the aching tooth. It felt like a raging tooth ache with an abcess. There was a foul discharge when I popped the bubble in the gum line. First my right lower molar, then my left one started to act up. I had zero issues up until shortly after the new generic change. Made an appointment with my dentist, he exrayed my teeth & didn't really note anything serious, other than a slight foggy area at the base. There were no cavities or abcesses. I explained how it was excruciating to bite down or chew, and I couldn't handle the pain anymore. It was the most uncomfortable thing ever. I stopped the medication a month ago and I started to feel better physically. I wasn't waking up feeling hung over, or experiencing joint pain & weakness. My right tooth started to feel better after a few weeks, my left molar seems to be less sensitive. I googled these symptoms, and discovered that they were reported side affects of Singulair. The prior brand of Montelukast did help with my allergies tremendously, however, I did notice the body aches, exhaustion & irritable mood. I didn't coincide this medi F 53 3 years

 1  Allergies & Sinus Infections Numbness all over body, especially arms, hands & throat @ night. Dry mouth and difficulty swallowing.Neck pain & stiffness. Chest pain & heart palpitations. Sore burning pain in arms, shoulders & back. Difficulty breathing. Weakness & Fatigue. Lightheaded & Foggy brain. I actually felt like this medication was causing me to have asthma attacks. It did help with my allergies & even my psoriasis. However, I'll deal with any of these symptoms every day of the week before the side effects from this medication. F 53 2 months

 1  Urticaria/food allergies Developed constant headaches and severe lower abdominal pain the first night of taking. Spent the next three days in bed with abdominal pain, sleeping about 18 hrs a day. Went to urgent care center for the abdominal pain, thinking maybe it was a terrible UTI. Had a UA done - nothing. They had no answers. Day 4 came and I didn't take the meds, started feeling better within hours. The rash, the reason I started taking this drug, Montelukast, got worse in the three days I took it. Seems like I was prescribed this in almost an off label manner for a rash that my allergist thinks might be food related. With the horrid side effects of this, I'd rather live with the rash. 53 3 days

 5  Chonic asthma Terrible nightmares, leg cramps, muscle aches, flu like symtoms. Singulair is wonderful except for the side effects. I took it for three years and had to stop because of bad dreams. I started taking again and got leg cramps, muscle aches and flu like symptons. I stopped for a few weeks, symptons were gone. Started taking it again, symptons returned. Now that I read comments about Singulair I see other related symptons such as low back pain, concentration problems, forgetfulness. I have been off for two weeks now. I'll see if other symtons get better too. F 54 3 years

 5  Sinuses completely plugged I have had increased ringing in my ears. Upon reading these reviews I realize that my sleep patterns could be altered by this med. I'm 54 years old (male) but until 1 1/2 years ago I could count on one hand how many days per year that I could breathe thru my nose. Now its completely open and I can actually smell things. I take mine in the morning & I think that my sleep symptoms are rather minimal because of that. It says on the bottle to take at nite but my mom always said not to take any maintenance med when you go to sleep. So I didnt. I feel that it is a wonderdrug and really like it. My ins covers it but for copay so it is a doable thing for me. I have NEVER taken any type of maintenance med!! I see on the receipt though that it would cost me about $4 per dose if I pay out of pocket. Dont know if its worth that! Perhaps if I go off it and the concrete sets in again I will think differently. Pretty Pricey!!! M 54 18 months

 5  Allergic Rhinitis Dry Mouth I don't have any problems taking this drug! It keeps my breathing open and clear! If I miss a dose or two I notice my breathing changes to having mucus and shorter breathes. I like going to the beach and this medication keeps my breathing clear and at full capacity! F 54 2 years

 4  daily migraines I've experienced no side effects that I know of although after looking at this site, I believe the med caused a few nights of unexplained sleeplessness. I'd heard that Singulair can help with migraines so, at my urging, my neurologist prescribed this med for me. It definitely has helped although I'm far from perfect. I'm taking this med vs. other daily preventatives because of dryness the others can cause (I have an autoimmune disease that causes dryness). My heart goes out to the parents here whose children have had negative side effects--esp the parent whose child took his life. Very useful website! F 54 25 days

 4  seasonal allergies to cedar/juniper I took Singulair last year for my allergic reaction to cedar and juniper pollen and it worked great for my sneezing/runny nose symptoms. When I first started taking it, I had some fun and unusual dreams for the first couple of weeks. Then those dreams turned into nightmares. I quit taking it when the cedar trees were done spreading pollen and the nightmares went away. It's a new year and I was having allergy symptoms again, so I started up with the Singulair a week ago. This time I went straight to the nightmares. I woke my husband up the other night yelling out in my sleep. Last night I had a series of sad and depressing dreams and this morning I feel terrible. I need to go off of this medication...it isn't worth it! F 54 7 days

 3  allergies and asthma None except I can't fall asleep when I take this stuff. Does an amazing job quelling allergic symptoms and asthma, especially for my cat allergy. But it does rev me up at night so I only take if dire need. F 54 3 years

 2  asthma/allergies I was 'sort of' fine the first 2 weeks, but the 3rd week brought on symptoms from hell. Sleeping problems (nightmares and feeling like I had electicity running through my viens)Extreme drowsiness & sleepiness in the day, mental fogginess, bone and body aches so bad I could not lay on my mattress at night. And I was unable to stay awake in the day - felt like I was drugged. Add to that water retention and face puffiness. Scary stuff this drug! Sadly, if it werent for the horrid side effects it would be great. My sneezing and nose dripping stopped, and my asthma symptoms improved! However, thanks but no thanks! They need to do some work with this drug. And why is everyone telling me (doctor and pharmacists) that this drug is well tolerated - when I read everyones comments it doesnt appear so at all.
