| 1 | Allergies and Asthma | Dizziness, very tired, headaches, sore throat, upset stomach, painful tummy, indigestion, mood swings, forgetfulness, mood swings, rash, depression. | Highly dissatisfied. I do not recommend. I suffer exercise and allergy induced asthma. I was using a rescue inhaler daily so my doctor suggested trying Singulair daily for 3 months. I've taken it for 25 days and will never again. I'm normally a very together, upbeat, organized person. I've had so many side effects in so many directions I'm in complete despair and kicking myself for taking the med so long. I had such "wuzzy brain" I thought I was pregnant. My inability to focus and function has been greatly impaired this month to the point of severely hurting my life. I fear I've permanently hurt my body with this drug. | F | 48 | 25 days 10 MG 1X day | 12/17/2016 | 1 | Asthma | Over time I was experiencing all of the bad side effects/ mood swings/ changes in personality/ thoughts of suicide/ weight gain/ tremors | F | 48 | 10 years one pill 1X day | 9/21/2016 | 5 | Asthma, COPD, Allergies | Stomach cramps, but only in the beginning of re-starting this medication. | Due to losing my insurance and financial challenges, I'd been off Singular for about a month, after taking faithfully for about three years with no promblems at all. I will never go off this medication again. I couldn't breath without it. My throat was so scratchy; I was short-winded, hacking cough, wheezing, using my inhaler way, way too much. I was miserable. Within 24 hrs of restarting Singulair, I could breath again. I'm having a little adjustment phase now (some cramping, and sleep disturbance), but because I had taken it for so long with no complications, I expect those to diminish in the next few days. This medication is not for everyone -- especially after reading some of the other posts regarding giving this to children. If it works for you, then it's fine, if not stop taking it(.) It's not as though the side effects aren't reported. Your pharmacy gives you the information when you make your purchase. That's the law. I love the stuff. | F | 47 | 3 years | 11/27/2009 | 5 | Asthma/recur Asthmatic Bronchitus | None; however my ears "ring" but that started after more than 2 years of using this drug so I doubt that's it. Did notice I can't eat almonds anymore (mouth hurts), though -- maybe it's the analgesic effect since you can't take asprin with Singulair either! | Wow! Terrific drug that saved my life! First got it when I had four (4) pluersies in my lungs while using Advair prescribed by my regular doc. (Advair/Serovent -- dangerous drugs). The Urgent Care doc suggested I use Singulair instead along with my rescue inhaler for acute stage. Presto! I got better. Now, I'm on it full-time and rarely use my rescue inhaler except if I get standard Bronchitus (from the kids). | F | 47 | 4 years | 12/13/2006 | 5 | asthma/allergies | Dry mouth initially - none since then. | Singulair has been a wonder drug for me. I was living at 50 - 70% lung capacity all year, and the side effects for me of Advair and other steroids were overwhelming. I now only use my inhaler when exercizing, and previously I was using it 6-8 times per day. I do believe strongly that medications affect people differently (I was a zombie with Allegra and Zyrtec, but not with Singulair), and so have no doubt that the low ratings of others on this site are valid. I would take issue, though, with the person who claimed that the people who rate the drug a 5 must work for the manufacturer since why else would they be on this site: I came to this site because I googled whether Singulair and Claritin could be taken at the same time, and after reading the responses, felt I should add my own experiences. I really appreciate this additional information regarding the drug, and will certainly keep it in mind as I continue to use it. | M | 47 | 4 years | 10/8/2007 | 5 | Chronic allergies and rhinitis | No side effects noticed. | This drug changed my life. I have struggled to breathe for the last 3 years and nothing helped for very long, not even my asthma inhaler, until my new doc gave me Singulair. | F | 47 | 30 days 10mg 1X day | 5/9/2011 | 5 | asthma | the drug has virtually cured my life-long moderate to severe asthma and it has greatly helped my allergies. i do notice that i feel depressed and anxious alot. i have trouble concentrating as well. i also have trouble losing weight. | with the knowledge that i am currently gaining on prescription drugs in general, i am very interested in stopping this drug asap. | F | 47 | 8 years 10 1X day | 2/15/2011 | 4 | Allergies | Took for 3 years. Joint and muscle pain along with weight gain. Mainly feet, hips and knees. Could barely get out of my car. Would go away once I got moving so was still able to exercise. All Drs baffled. I'm fit so this all didn't make sense. Took it upon myself to research. Been off for a week. Joint pain almost gone. Coincidence? Gained 15-20 lbs despite healthy lifestyle. Not sure what else was an effect. Excited to see the new. Me:) | Negatives outweigh benefits. Not worth it. | F | 47 | 0 days 1X day | 8/4/2023 | 3 | seasonal allergies | First year: Singulair with Nasonex - no notable side effects (6 month period). Second year: Singulair with Flonase generic - in 4th month of use I started waking up with feelings of depression that would not linger after I was awake. I can not be sure that the depression was caused by Singulair. I weaned myself off Singulair in a week and continued taking Flonase generic. A week later I noticed that my mental capacity had improved. While on Singulair I had difficulty in the evening getting motivated mentally to do anything, and also found it difficult to concentrate on complex tasks (computer programmer). The week after getting off Singulair I noticed a significant change. My mental capacity returned to normal (in the evenings: ability to focus on complex tasks, motivated to perform problem-solving tasks). | This is the second year I have been on Singulair. I wuuld start in February and take it til around August/September to treat tree and grass allergies. The first year I started in late March, but did not notice any side effects; I also used Nasonex; Singulair was not sufficient by itself to deal with my allergy symptoms. The second year I switched from Nasonex to a Flonase generic. Without Singulair and a steroid nose spray during my allergy season, I was unable to concentrate during the day (fuzzy, floating feeling from allergies, sinus pressure, etc), had to deal with sinus congestion, occasional sinus infections, frequent sore throat, cough, sneezing, physical fatigue, aches throughout body, and difficulty sleeping. Currently I am using the Flonase generic only. I still experience muscle aches throughout my body, physical fatigue, some sinus congestion, and sore throat, but have decided it is worth it to regain my ability to concentrate in the evening and feel motivated mentally throughout the day. Additional notes: I normally tend to have mild anxiety and difficulty sleeping, but do not experience significant feelings of depression without a cause. | M | 47 | 15 months 10mg 1X day | 5/19/2010 | 3 | Severe Allergies | I never had any side effects while taking Singulair but since CVS/Caremark changed to the generic brand Montelukast, I have had many symptoms. Depression, suicidal thoughts, mood swings, anxiety which I have never had in my life, crying, night sweats, dizziness, frustration, trouble concentrating and numbness. I thought the symptoms were due to me being pre menopause but my suicidal thoughts are so bad I think it may be from the generic brand. I stopped taking it last night and I'm going to see what happens. I'm nervous about my allergies now because Singulair helped me for years, but I can't put my family through these mood swings anymore. | F | 47 | 5 years 10mg 1X day | 3/8/2014 | 3 | Allergies | At full dose, developed heartburn and burning tongue (from the heartburn). Apparently it changed my pH. | I cut the pill in half and the heartburn goes away but so does most of the benefits. When I take it full dose, I can breath deep through my nose and chest. At half does, I'm back to lung spasms and heavy breathing with exercise. Too bad about the heartburn. | F | 47 | 30 days | 8/11/2009 | 2 | Combat sinus allergy symptoms | Panic attacks, feelings of impending doom, manic and suicidal thoughts. Episodes last from two to five hours. | I have allergic onset asthma and have had chronic sinusitis. I didn't notice any improvement with or without the Singulair. The panic attacks are worse than the sinusitis symptoms. Will discontinue the Singulair in hopes that the panic attacks do not return. | F | 47 | 7 weeks | 8/24/2009 | 2 | allergies and cough | weight gain, mood swings, manic behavior, nightmares, and anger | great with allergies but the side effects are worse than the allergies. | F | 47 | 3 months 5 mb 1X day | 6/24/2010 | 2 | Allergy induced asthma attack | Major depression; uncontrollable, irrational rage/anger; major anxiety; abnormal heart palpitations; had no desire to socialize; feeling of bleakness/no hope | Worked wonderfully for asthma relief, however, absolutely would NOT ever take again due to horrific side-effects ... could not control mood swings. Was uncontrollably depressed and felt like dying. In short time I took Singulair, due to my behavior, was risking my relationships with husband, daughter, friends. Felt as if I was having a psychiatric breakdown, because I couldn't understand the depression, anger, anxiety and could not stop feeling horrific, or taking it out on family, friends. | F | 47 | 10 days 10 mg 1X day | 1/10/2011 | 1 | allergies | My 16 yr old daughter had severe nightmares and numbness in her feet. I took just 2 doses and had severe itching and stopped. | My daughter took singular for about 2 months. It did help her allergies, but she started having very bad dreams and numb feet, didn't make the connection to the drug. I took 2 doses after she had been on those 2 months to see if it would help my allergies and had an immediate reaction. I looked up side effects and was horrified and what I read. We both stopped right away. This was about 3 years ago. Last year I got into a conversation w/a coworker whose 8year old was having having all kinds of problems with behavior. I found out the child was on singular and I told her to look it up. She took her child off singular and then thanked me "for saving my daughter". This stuff is lethal. The FDA is aware of problems. Go to the FDA website: do a search for Merck singular 2008. | F | 47 | 1X day | 6/2/2011 | 1 | year round allergies | mood swings, nightmares, tightness in chest, dizzy, weight gain, can not focus, severe depression. | Drug works great for allergies - but not worth the side effects. There are other drugs that work as well that will not wreck your life. Working now on improving immune system with diet and natural supplements and natural treatments for the allergies. | F | 47 | 2 months | 4/8/2007 | 1 | asthma/allergies | Moody,unable to focus,rash back,exhausted,loss apetite,depressed,angry,can't cope. | Seemed to wk. very well for allergies-was able to give up inhaler, but not worth the side effects. Still trying to connect the dots. Anyone trying this drug should monitor any changes very closely. *My periods got heavey and out of wack. Acne itch on back*-*Never had these problems before.* Feel like this drug may have changed my hormonal balance-trying to figure out. Have other ladies exp. this? Going to stop this drug today and see if I can get back myself. | F | 47 | 6 weeks | 5/8/2006 | 1 | Asthma | Severe sinusitis. I started taking singulair for asthma which was not that bad. Seasonal. Soon afterwards I developed severe upper respiratory infections. I no longer take singulair but am on 10mgs of prednisone a day to keep my nasal passages unblocked. I've gained 30 pounds and are dealing with the other side effects of being on steroids for 3 years now. | I really dind't need sigulair at all. My doctor just thought it would help me manage my asthma. Now I'm worse off. | M | 47 | 1 years | 10/18/2005 | 1 | chronic rhinitis | paranoias, hallucinations, suicidal thoughts and phonism. very terrible side effects. i could not control myself. | singulair was very effective for alleviating the rhinitis symtoms, but i was also hospitalized 7 days for 'initiative psychosis symtoms'. luckily, i remember singulair is somewhat related to mood and behavior change. i stopped taking singulair for 5 days and all horrible side effects were gone. i am a sane myself. | M | 47 | 3 years | 8/27/2008 | 1 | ASTHMA | Severe heart palpitations, exhausted, soar neck muscles, depressed and inattentive. Mostly the heart palpitations, they are very severe. | Had heart palpitations when on the serevant disk inhaler a few years back as well. Same thing, my heart was freaking out. Visited a cardiologist and couldn't find anything wrong. Took myself off it and the symptoms went away. | F | 47 | 2 months | 3/29/2009 |
