I Am Suffering From Severe Itching From Lisiniprol Allergic Reaction

I am suffering from severe itching from lisiniprol allergic reaction with deep red rashes over my body. The itching is nearly unbearable, I was admitted overnight to hospital and discharged during the day because my symptoms (gross swelling at my mouth and similar rashes) appeared to be alleviated, only to reoccur at bedtime. What can I do to stop this torture?
