What is the treatment for acute drug reaction to omeprazole ,had chills , bone ,joint pain ,hand feet twitch,dizzy, rash come n gofrequent urination?

Here are some...: At suspecting drug allergy, stop the offending drug and seek evaluation / counseling for possible use of antihistamine and a short 3-5 day course of steroid; if short of breath occurs, take emergency visit right away; if just having bearable itch with no swelling of mouth, take antihistamine and wait out-if not getting better as expected in 3-5 days, seek medical attention timely.
