I'm really sorry to hear that your Mum's medication seems to be making things worse for her, and that she is feeling so bad at the moment. Please do give us a call on 0808 800 0303 and speak to one of our specialist Nurses about this, they will be able to help with your questions and what to do to help you Mum.
I hope things improve for her soon.
Take care and best wishes to you both.
