Remifentanil is used to relieve pain during and after surgery or other medical procedures. It is also used with other medicines (e.g., isoflurane, propofol, midazolam, thiopental, Diprivan®) just before or during an operation to help the anesthetic work better.
Remifentanil belongs to the group of medicines known as narcotic analgesics (pain medicines). It works by acting on the central nervous system (CNS) or brain to relieve pain.
Remifentanil is to be administered only by or under the immediate supervision of your doctor.
This medicine 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 this medicine, the following should be considered:
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.
Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of remifentanil in children when given with an anesthetic before or during an operation. However, safety and efficacy have not been established in children for the relief of pain after surgery.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of remifentanil in the elderly. However, elderly patients are more sensitive to the effects of remifentanil, which may require an adjustment in the dose for patients receiving remifentanil.
