IGeneric name: Oprevelkin
Trade name: Neumega^®
Other names: IL-11

Chemocare.com uses generic names in all descriptions of drugs. Neumega is the trade name for Oprevelkin. IL-11 and Interleukin-11 are other names for Oprevelkin. In some cases, health care professionals may use the trade name Neumega or other names IL-11 and Interleukin-11 when referring to the generic drug name Oprevelkin.

Drug type: Interleukin-11 is a biologic response modifier. Interleukin-11 classified as a cytokine. (For more detail, see "How this drug works" section below).

What Interleukin-11 is used for:

Oprevelkin is used to stimulate the bone marrow to produce platelets in order to prevent low platelets that may be caused by chemotherapy. Platelets are blood cells that allow the blood to clot, and prevent bleeding.
Oprevelkin may be given to decrease the need for platelet transfusions.
Oprevelkin is not indicated for myeloid malignancies (diseases that start in the bone marrow such as leukemia).
Oprevelkin is a support medication. It does not treat cancer.

Note: If a drug has been approved for one use, physicians may elect to use this same drug for other problems if they believe it may be helpful.

How Interleukin-11 is given:

Oprevelkin is given by subcutaneous (the layer between the skin and muscle).
Oprevelkin is usually given 6-24 hours after chemotherapy.
Oprevelkin is generally given on a daily basis. The number of days you receive oprevelkin will be prescribed by your doctor.
You may be taught to give these shots to yourself once a day after chemotherapy, or they may be given to you by another healthcare provider.
The amount of oprevelkin that you will receive depends on many factors, including your height and weight, your general health or other health problems, and the type of cancer or condition being treated. Your doctor will determine your dose and schedule.

Side effects of Interleukin-11:
Important things to remember about the side effects of oprevelkin:

Most people do not experience all of the side effects listed.
Side effects are often predictable in terms of their onset and duration.
Side effects are almost always reversible and will go away after treatment is complete.
There are many options to help minimize or prevent side effects.
There is no relationship between the presence or severity of side effects and the effectiveness of the medication.

The following side effects are common (occurring in greater than 30%) for patients taking Interleukin-11:

Swelling (water retention - most common in the hands, feet and ankles)
Nausea and vomiting
Mouth sores
Diarrhea
Shortness of breath

These side effects are less common side effects (occurring in about 10-29%) of patients receiving Interleukin-11:

Headache
Fever
Rapid heart beat/palpitations (see heart problems)
Dizziness
Insomnia (see sleep problems)
Cough
Rhinitis/pharyngitis (see cold symptoms)
Rash
Conjuctival infection (see eye problems)
Bone or joint pain
Temporary anemia (low red blood count - will resolve on it's own within a week after oprevelkin is discontinued).

A serious, but very uncommon side effect of oprevelkin is "capillary leak syndrome" or "vascular leak syndrome." Capillary leak syndrome is a potentially serious disease in which fluids within the vascular system (veins and capillaries) leaks into the tissue outside the bloodstream. This results in low blood pressure and poor blood flow to the internal organs. Capillary leak syndrome is characterized by the presence of 2 or more of the following 3 symptoms; low blood pressure, swelling, and low levels of protein in the blood. Your doctor will monitor these things carefully while you are taking oprevelkin. You should notify your doctor immediately if you notice dizziness (especially when changing position), sudden swelling or rapid weight gain, little or no urine output (for 8-12 hours), shortness of breath, difficulty breathing, irregular heart beats, or chest pain.

Not all side effects are listed above. Some that are rare (occurring in less than 10% of patients) are not listed here. However, you should always inform your health care provider if you experience any unusual symptoms.

When to contact your doctor or health care provider:

Seek emergency help immediately and notify your health care provider, if you experience the following symptoms:

Shortness of breath, wheezing, difficulty breathing, closing up of the throat, swelling of facial features, hives (possible allergic reaction).

Fever of 100.5º F (38º C) or higher, chills (possible signs of infection)
Dizziness (especially when changing position), sudden swelling or rapid weight gain, little or no urine output (for 8-12 hours), shortness of breath, difficulty breathing, irregular heart beats, or chest pain.

The following symptoms require medical attention, but are not an emergency. Contact your health care provider within 24 hours of noticing any of the following:

Nausea (interferes with ability to eat and unrelieved with prescribed medication)
Vomiting (vomiting more than 4-5 times in a 24 hour period)

Monitoring and testing:

You will be checked regularly by your health care professional while you are taking oprevelkin, to monitor side effects and check your response to therapy. Periodic blood work to monitor your complete blood count (CBC) as well as the function of other organs (such as your kidneys and liver) will also be ordered by your doctor.

How Interleukin-11 works:

In the body's bone marrow (the soft, sponge-like material found inside bones) blood cells are produced. There are three major types of blood cells; white blood cells, which fight infection; red blood cells, which carry oxygen to and remove waste products from organs and tissues; and platelets, which enable the blood to clot. Cancer treatments such as chemotherapy and radiation therapy can effect these cells which put a person at risk for developing infections, anemia and bleeding problems. Colony-stimulating factors and growth factors are substances that stimulate the production of blood cells and promote their ability to function. They do not directly affect tumors but through their role in stimulating blood cells they can be helpful as support of the persons immune system during cancer treatment.

Oprevelkin is a cytokine that stimulates the production, maturation and activation of platelets. In patients receiving chemotherapy, Oprevelkin can accelerate the return of platelets to normal levels, reducing the thrombocytopenic (low platelet) phase (the time in which people are most susceptible to bleeding), and decrease the need for platelet transfusions.
