I Have Been Taking Lansolprazole 15 Mg For Many Years.

I have been taking lansolprazole 15 mg for many years. Within the last few months, I am very itchy and have hives. The itch is internal as well as external. I haven't been eating anything different. I used All free detergent and products for sensitive skin. I was wondering if theLansolprazole could cause my symptoms.
