Is This Normal Of Getting Skin Rashes After Taking Eso Kit?

I am Paul from Nairobi, Kenya. I have had duodenal ulcers for the last 16 years and was last week put on 7-day ESOkit treatment. But on the 3rd day, I started developing itches on my body; after completing the full 7-day kit yesterday, I have developed massive skin rash all over. Is this normal... when will/ will the rashes end? And should I continue with the single tablet a day Esomeprazole 40mg for which I was prescribed over the next 14 days?
