Alfentanil (patient information)

About your treatment

• Your doctor has ordered alfentanil, a strong analgesic (painkiller), to relieve your pain. The drug will be added to an intravenous fluid that will drip through a needle or catheter placed in your vein.
• You probably will receive alfentanil continuously for around-the-clock pain relief. Your doctor also may order other pain medications to make you feel more comfortable. This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
• Your health care provider (doctor, nurse, or pharmacist) may measure the effectiveness and side effects of your treatment using laboratory tests and physical examinations. It is important to keep all appointments with your doctor and the laboratory. The length of treatment depends on how you respond to the medication.

• Before administering alfentanil,

• Tell your doctor and pharmacist if you are allergic to alfentanil, morphine, codeine (or medications that contain codeine such as Tylenol with Codeine), hydrocodone (e.g., Vicodin), hydromorphone (e.g., Dilaudid), oxycodone (e.g., Percocet), oxymorphone (Numorphan), or any other drugs.
• Tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially antidepressants, sedatives, sleeping pills, tranquilizers, and vitamins.

Administering your medication

• Before you administer alfentanil, look at the solution closely. It should be clear and free of floating material. Gently squeeze the bag or observe the solution container to make sure there are no leaks. Do not use the solution if it is discolored, if it contains particles, or if the bag or container leaks. Use a new solution, but show the damaged one to your health care provider.
• It is important that you use your medication exactly as directed. Alfentanil can be habit forming. Do not administer it more often or for a longer period than your doctor tells you. Do not change your dosing schedule without talking to your health care provider. Your health care provider may tell you to stop your infusion if you have a mechanical problem (such as a blockage in the tubing, needle, or catheter); if you have to stop an infusion, call your health care provider immediately so your therapy can continue.
