Cytogam

What is CYTOGAM?

(CYTOGAM) This medication is used to prevent a certain serious viral infection (cytomegalovirus-CMV) in persons having an organ transplant (kidney, heart, liver, lung, pancreas). During the transplant process, the body's defense system (immune system) is weakened to prevent the body from attacking (rejecting) the new organ. A weakened immune system increases the risk of a serious, possibly fatal infection with CMV. This medication is made from healthy human blood that has a high level of certain defensive substances (antibodies) that help fight CMV. This medication is often used with the antiviral medication ganciclovir.

How should I use CYTOGAM?

This medication is given by slow infusion into a vein as directed by your doctor. Your health care professional will start the medication slowly while monitoring you closely. If you have few or no side effects, the medication will be given faster. Tell your health care professional right away if you experience any side effects such as flushing, chills, muscle cramps, back/joint pain, fever, nausea, vomiting, or shortness of breath. The infusion may need to be stopped or given more slowly. The first dose is usually given within 3 days of the transplant, followed by more doses every 2 to 4 weeks or as directed by your doctor. The dosage and frequency depends on your medical condition, weight, and response to treatment. If you are giving this medication to yourself at home, learn all preparation and usage instructions from your health care professional. Before using, check this product visually for particles or discoloration. If either is present, do not use the liquid. Learn how to store and discard medical supplies safely.

What should I watch for while using CYTOGAM?

This medication may rarely cause serious blood clots (such as pulmonary embolism, stroke, heart attack, deep vein thrombosis). You may be at increased risk for blood clots if you are an older adult, are severely dehydrated, have a catheter in a vein close to your heart for administering medications, or have a history of blood clots, heart/blood vessel disease, heart failure, stroke, or if you are immobile (such as very long plane flights or bedridden). If you use estrogen-containing products, these may also increase your risk. Before using this medication, discuss the risks and benefits and if you have any of these conditions, report them to your doctor or pharmacist. The risk of blood clots may be decreased by infusing this medication more slowly or by using a less concentrated form of this medication if available. Being adequately hydrated before receiving this medication may also help reduce this risk. Get medical help right away if any of these side effects occur: shortness of breath/rapid breathing, chest/jaw/left arm pain, unusual sweating, sudden dizziness/fainting, pain/swelling/warmth in the arm/leg, sudden/severe headache, trouble speaking, weakness on one side of the body, sudden vision changes, or confusion.

What if I miss a dose of CYTOGAM?
