It sounds like you and your stomach really did not agree with Vicodin. This is not all that uncommon of a reaction to a narcotic pain killer, though your reaction does sound quite pronounced. Vicodin is a combination medicine that contains the pain killer and fever
reducer acetaminophen (also known as Tylenol) and the narcotic pain killer hydrocodone. The nausea and vomiting that you experienced does not technically mean that you had an allergy to hydrocodone. To a doctor
, an allergy means that your immune system had a reaction to the drug which can result (in addition to nausea and vomiting), in hives
, lose blood pressure, and difficulty breathing. It is likely that you will have similar reactions to other oral narcotic pain killers. Nevertheless, you should if you are ever in a position that you need to receive IV pain killers, make sure that you let the doctor know that you had this reaction.
I suggest that you schedule an appointment with the physician that prescribed you the Vicodin. Explain the reaction to him or her. There are other options for pain control that you may tolerate better. Hopefully, your sinus an dear infection will clear up soon and you won't have to take any more pills.
