Before using fosaprepitant

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 fosaprepitant, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to fosaprepitant 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 have not been performed on the relationship of age to the effects of fosaprepitant injection in children younger than 6 months of age. Safety and efficacy have not been established.

Geriatric

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

Breastfeeding

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.
