This drug has worked fabulously for controlling my daughter's asthma. HOWEVER,it's side effects have been a nightmare. Began taking it after 3rd birthday, would not longer sleep in her bed, up numerous times /night, horrible temper tantrums, weepy, moody/irritable. Everyone thought she was just "going through a phase." Docs assured me could not be because of meds. They increased her dosage when s...

I had bouts of allergic asthma and needed to use my albuterol inhaler more and more. My allergy doc recommended Singulair. I have taken it every evening now for 21 years. I no longer need to use my inhaler!!!!!!

I've been taking Singulair for over 10 years. It was life changing for me. No more need for inhalers unless I get sick.

I am in medical healthcare and my review is from research on this medication. This is a BLACK BOX warning drug, meaning that the patient takes it at their own risk. It changes a part of the airways that affects inflammation, BUT will also change the chemistry of the brain (not blood brain barrier as some say, but chemically). It WILL cause SUICIDAL IDEATION in both adults and children. In fact some people have taken their lives on this drug after using it for a short time to a long time. Do NOT, I repeat, DO NOT take this drug. It is promoted to make money for pharmaceuticals reasons, and not to help people. It will cause lifelong brain damage to anyone who continues to use it. But if Stopped immediately, patient can return to normal if it is not too late. No doctor will tell you this because this is FDA approved even though it should not be. Protest to FDA and take this medicine off the market. Read More Read Less

while it helped control seasonal allergies to a degree, the horrible and lasting side effects were not worth any of the relief.

My blood pressure (under medication) was typically 128/68. After using Singulair for 10 days, my BP spiked at 205/103. With Doctor approval, I stopped taking this medication !!

Singulair seems to work for my asthma and sinus congestion. Sadly I have been having blood pressure issues and no idea as to why its so high. I have been reading and a lot of users have experienced same thing, blood pressure way up while using Singulair. I hope more is done to notify people of this, I am upping my blood pressure pills for no reason if this is actually the cause, stopping cold turkey to see if pressure goes back to where it was. If you have sudden blood pressure issues please look into this pill, seems to spike it in some people. Read More Read Less

Singular worked for me while I was taking it. When I would fall asleep I would have some of the most vivid nightmares. When I informed my physician of the dreams I was having he just nodded his head and said “it does that to some ppl”. I would awake from my dreams with crazy thoughts. This medication can put you in a very dark place. I would not recommend taking it.

This is a terrible "medication." Regrettably, I've been taking this for years to preventively control asthma and have had concomitant issues with depression, agitation, anxiety, rapid heartbeat and feelings of hopelessness DUE TO this drug; these are NOT due to other circumstances, physical or mental, and I am absolutely appalled that my physician has NEVER spoken with me about side effects of this very dangerous medication. I only learned of its deleterious side effects until recently from a pharmacist. I've stopped taking this very dangerous drug and have noticed a positively remarkable RETURN to NORMALCY of my mood, concentration and well being. I remain appalled, if not horrified, over how I've suffered while taking this "medication." CONSUMER BEWARE! (I am in my 60's. Your chart below only goes up to age 24).Read More Read Less

So I started taking Singulair yesterday. A few hours later my airway and my lungs started feeling clearer. My initial thought was that it was temporary and my airway would go back to being lined with mucus and my lungs would go back to feeling like wet sponges through which I was constantly coughing to bring up mucus, but still feeling like it was clogged. But, here I am, day 2, lungs and airway feeling clear like they haven't in a long time. Pretty excited.

It works very well for my asthma, caused by allergies. But it causes tooth pain for me! It seems that it causes the nerves to overreact terribly. Been to the dentist multiple times, he had no explanation. I stopped taking Singulair, and after a few days the pain was pretty much gone. I just started taking it again because allergies are bad, and here we go, the pain is back. I hate to say it, but I cannot take this medication! (I'm a 65 year old female)

While it works to control Asthma, it’s not worth the risk. My son started taking it at 5 years old. It does cause depression & suicidal thoughts!! as well as anxiety. My son could never sleep, had tremors, excessive sweating too. It took him getting to 18/19 years old to be able to finally realize all his depression & mood was from his medicine. He stopped taking it on his own & he saw such a huge difference. Said he would never take it again and that he felt like the darkness had finally lifted. Don’t let you kids take it. We had years of issues & never realized it was Singulair.Read More Read Less

My son started taking this in Kindergarten. He was the sweetest, kind hearted soul and completely changed a few days after starting Singular. The pediatrician assured me there is ZERO way it could be the cause of my sons dramatic behavioral changes because it can’t cross the blood brain barrier therefore doesn’t affect the Central Nervous System. My son tried opening the car door when I was driving down the street, he started chocking his little brother in Target and was down right aggressive. His eyes looked like all the love was striped from his body. That’s the only way to describe it. I took him off the medication and within a week or 2 he was back to himself. I don’t recommend this medication to anyone!!!Read More Read Less

WARNING!!! PLEASE READ. It was explained that this could cause mental or phycological reactions. I proceeded with caution because like many of you I was desperate to find relief. I have been taking for 3 weeks. I've had increasing irritability, anger and uncontrollable outbursts. Yesterday I felt overwhelmingly violent and took an AXE to my backyard to release the anger before I hurt myself or someone else. Later, out of nowhere, I started having SUICIDAL THOUGHTS that even looking at a butterknife I new I could do IT! I finally called someone to help talk me through it. I racked my brain, did more reading and new 100% it was this drug! I am now trying to find the safest way to taper off because I am also afraid of what reactions will occur if I stop suddenly.

This drug caused me to have brain damage that can be seen in an MRI imaging. The damage seems permanent. My life has changed in a severe and detrimental way. I think of suicide EVERYDAY after stopping it in 2013. Now it's June of 2021. I have finally found a lawyer who may help me sue MERCK. But don't know if I will make it until the suite goes to trial. I may become homeless next month. MERCK hopes you never read this review because they are a making a huge profit from this drug. And right from the beginning, they knew this drug goes primarily through the blood brain barrier. They were trying to develop a drug to treat a brain disease such as multiple district for multiple sclerosis. When they found it didn't work for that condition, they sought out other medical problems I try to use it on. But this drug is far more damage than good. WebMD needs to stress this more. Many people have developed mental health and neurological problems from taking thus drug. Singular should have never sought to sell it. The potential side effects are far too severe to risk taking this drug for allergies or asthma. I started out what's some sinus issues and now my sinuses are not better and my life will never return to normal and I may kill myself eventually. I truly have nothing to live for anymore.Read More Read Less

Watch out for side effects. It had a dramatic impact on my mood. I stopped and started again 3 times over a year to see if it was truly the Singulair. It was.

This medicine was prescribed for my 8-year-old daughter. We started her on it because she was sent home from school with a runny nose and missed 10 days due to Covid policies. We wanted her to have the best chance to get to go to school during allergy season. Like others have said, I wish we would have read more about possible side effects. Since she's been taking this, her behavior has changed drastically to the point that the last few days she has been unrecognizable. She is angry, aggressive, and screams and lashes out sometimes for no reason. She is usually an extremely happy, easygoing child. I was ready to take her to a counselor when my husband looked at the side effects. We stopped use immediately. I'm hoping it doesn't take too long to get out of her system. We would rather her deal with allergy symptoms than to not ever feel like herself. Read More Read Less

It's not been perfect but has helped. I haven't had any of the bad effects I've read in all the other reviews. (I actually wonder if they are using this drug as a scapegoat for their issues). After years of taking this, a mix up with the pharmacy and needing a call to Dr for refill, I ended up not taking it for a couple weeks. I had lousy allergy/sinus crud that makes people look weird at you during this Covid19 snafu.
