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.

Dreams are not bad, just different. My face is so dry that I've had to apply a combination of lubriderm lotion, coconut oil, and vitamin e oil twice a day, generously, to get it back to normal. It's so dry that it soaks all of that up and I'm still not shiny or oily looking. Before this moisturizing regimen, my skin has red blotches where skin was flaking. I've been drinking a couple liters of water a day (mostly in the evenings) and still fibs my self feeling very thirsty while I'm asleep, even waking up from dry throat.

Additional Drug Information


* Warning: The facts and figures contained in these reports are accurate to the best of our capability; however, our metrics are only meant to augment your medical knowledge, and should never be used as the sole basis for selecting a new medication. As with any medical decision, be sure to work with your doctor to ensure the best choices are made for your condition.

* 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.
