Wikipedia

Montelukast (trade name Singulair) is a leukotriene receptor antagonist (LTRA) used for the maintenance treatment of asthma and to relieve symptoms of seasonal allergies. Montelukast comes as a tablet, a chewable tablet, flash tablet and granules to take by mouth. Montelukast is usually taken once a day with or without food. Montelukast is a CysLT1 antagonist; it blocks the action of leukotriene D4 (and secondary ligands LTC4 and LTE4) on the cysteinyl leukotriene receptor CysLT1 in the lungs and bronchial tubes by binding to it. This reduces the bronchoconstriction otherwise caused by the leukotriene and results in less inflammation.

I’ve been disabled this morning by the debilitating back pain in my mid back. It’s incredibly painful to move around, I was crawling on all fours this morning trying to get to some meds for pain relief but couldn’t get to them myself. I woke up my wife to assist. I took a muscle relaxer which seems to help, but I won’t be taking anymore Singulair.

Definitely from the use of Singulair. I gained 13 lbs in my mid section in one month. I couldn’t get it off and I have never struggled with weight issues. As soon as I stopped using it the weight started to drop. Still seeing hair thinning. I wish they would list those side effects because they are side effects of that medication.

* About FAERS: The FDA Adverse Event Reporting System (FAERS) is used by FDA for activities such as looking for new safety concerns that might be related to a marketed product, evaluating a manufacturer's compliance to reporting regulations and responding to outside requests for information. Reporting of adverse events is a voluntary process, and not every report is sent to FDA and entered into FAERS. The FAERS database may contain duplicate reports, the report quality is variable, and many factors may influence reporting (e.g., media attention, length of time a drug is marketed, market share). For these reasons, FAERS case reports cannot be used to calculate incidence or estimates of risk for a particular product or compare risks between products.
