Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to obiltoxaximab or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.
