“Started on 25mg. Incresased to 50mg @ day 18. All well. Then at day 28 I woke up swollen - all body edema: face, eyes, trunk, legs, arms. Discomfort when walking, when inhaling and stomach pressure and discomfort when eating. Went back to 25mg, symptoms started to subside at day 33. HR went up (+20bpm under effort) but also down at rest (-ca 10 bpm, to 40bpm and occasionally below).”

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.
