infliximab-qbtx is available only with your doctor's prescription.

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For infliximab-qbtx, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to infliximab-qbtx 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.

Pediatric

Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of infliximab-qbtx injection for the treatment of Crohn disease or ulcerative colitis in children 6 years of age and older. However, safety and efficacy have not been established in children younger than 6 years of age.

Appropriate studies performed to date have demonstrated that infliximab-qbtx injection is not helpful in children with juvenile rheumatoid arthritis. Efficacy has not been established.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of infliximab-qbtx injection in the elderly. However, elderly patients are more likely to have infections, which may require caution in patients receiving infliximab-qbtx injection.

Breast Feeding

There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.
