“Most effective antihistamine I've used for environmental allergens and MCAS related angioedema and urticaria flare ups but the bipolar-like manic feeling and inadvertent behavior symptoms are too much to contend with. Also induces balance issues and intention tremor for me. I had these same side effects when I last used it daily, longer than a week, a few years ago. I have used it no more than an occasional single dose, less than once and had no side effects. Regular use seems to be what triggers these manic symptoms that cease within 10 days of discontinuing.”

* 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.
