Reader Question: "Can someone can have an adverse reaction to Motrin when that same person has taken it in the past without problems?"
Dr. Jared C. Rogers, Medical Director, Hospital Medical Affairs at Methodist Medical Center:
The answer to that question is: "yes." It is not at all uncommon to have taken a medication in the past and experienced no problems only to subsequently have an adverse reaction with taking the same medication. If the reaction is truly an allergic reaction such as hives, swelling of the inside of the mouth or trouble breathing, a person actually has to have had exposure to the drug, or one very similar to it, previously in order to have that type of reaction.
