[|Human|] My mother is taking deanxit for the last 10 days two tablets daily one in the morning and one at miday. Last night she experienced tachycardia as soon as she went to bed. It took almost an hour to stop and she experienced some numbness on her left hand. Today she feels ok and she thinks to go to the doctor tommorrow if she have the same experience tonight. My mother is 87 years old
[|AI|]  Hello, I would explain that her symptoms could be related to cardiac arrhythmia.  For this reason, I would recommend performing a resting ECG and some blood lab tests (complete blood count, blood electrolytes, thyroid hormone levels). Density can lead to QT prolongation and thus increase the risk for cardiac arrhythmia. Reducing its dose may be needed if all the above tests result normal.  Hope I have answered your query. Let me know if I can assist you further.
