Before Using

Drug information provided by: Merative, Micromedex®

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 this medicine, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to this medicine 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

Use is not recommended in children. Safety and efficacy have not been established.

It should not be used to relieve pain after the surgical removal of tonsils or adenoids in children. Severe breathing problems and deaths have been reported in some children who received codeine after tonsil or adenoid surgery.

Geriatric

Although appropriate studies on the relationship of age to the effects of codeine and chlorpheniramine combination have not been performed in the geriatric population, no geriatric-specific problems have been documented to date. However, elderly patients are more likely to develop age-related liver, kidney, or heart problems, which may require caution and an adjustment in the dose for patients receiving this medicine.
