Before Using This Medicine
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 morphine, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to morphine 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.
Appropriate studies have not been performed on the relationship of age to the effects of morphine epidural injection in the pediatric population. Use of morphine epidural injection is not recommended in children.

However, elderly patients are more likely to have age-related heart, stomach, or lung problems, which may require caution and an adjustment in the dose for patients receiving morphine epidural injection.
