Can a new manufacturer of the same meds I've been on cause hives or an allergic reaction? Only new med I took was Mucinexx DM. Maybe Mucinexx is prob?

Since your reaction was not serious, consider challenging yourself by eating the berries. If nothing happens, then it is not from food allergy. However be aware that the next reaction may be more widespread if you are truly allergic. ...Read more
