My wife was prescribed utodin for stomach pains that the doctor said was from early contractions, most like braxton hicks contractions. However, we are not very sure if the pains are contactions at all. Anyways, after taking the tablet, she has shivering and palpitations and strange tingling all over the body. I understand this is a normal side effect to the meds but will it occur even if they were genuinely contractions?
