Taking molipaxin for anxiety and depression. Losing weight and started shaking. Worrisome

My wife,s weight has dropped to 7 stone over recent months.She has been diagnosed with anxiety / depression and was prescribed 1@50mg Molipaxin to be taken before retiring to bed. her whole body shakes uncontrollably Throughout the day which is is very upsetting for her and myself.Her GP then ordered her to stop the medication immediately and a blood sample appointment arranged for Thursday. Last night the shaking became that severe the bed was also shaking. I panicked and begged her to take to take the medication which after a short period stopped the shaking allowing both of us to get some sleep. I was awoke at approx 6 am this morning when the shaking resumed.I panicked again and after much begging and crying made her take the medication again which again reduced the the shaking to almost nothing .She is petrified of being certified and I XXXXXXX t know what damage I have done .I have stayed of work the last 9 days to look after her ,making sure she is eating and drinking adequately .I am scared of losing her and starting to suffer also. PLEASE HELP !
