I Used Efudix For 21 Days BD And During The

I used Efudix for 21 days BD and during the last 5 days felt very ill as if I'd been poisoned. Vomiting bile and mucus, itchy skin, oozing blisters, stomach cramps, sleeping badly, irritability, painful joints and muscles. I have not changed my life style other than apply this cream. Went to a doctor who prescribed Maxalon. Do you have any suggestions. Thank you, Gayle
