Warnings

None
Cautions
Hemolysis may occur, particularly in individuals at high risk (eg, thrombocytopenia, bleeding disorders)
Monitor patients at increased risk of thrombosis or thrombotic complications for at least 24 hr
Not for intravenous administration
Hypersensitivity reactions, including anaphylaxis, may occur; history of prior systemic allergic reactions to human immunoglobulin preparations places patients at greater risk; have epinephrine available for treatment of acute allergic symptoms; patients with isolated immunoglobulin A(IgA) deficiency may develop severe hypersensitivity reactions to treatment, or subsequently, to the administration of blood products that contain IgA
A transient rise of the various passively transferred antibodies in the patient’s blood may result in misleading positive results of serologic tests; passive transmission of antibodies to erythrocyte antigens (eg, A, B, and D), may interfere with serologic tests for red cell antibodies such as the antiglobulin test (Coombs test)
Administration may interfere with development of an immune response to live attenuated virus vaccines; if feasible, delay immunization with measles vaccine for 4 months and other live attenuated virus vaccines for 3 months after vaccine administration
Because vaccine is made from human plasma donors hyper-immunized with rabies vaccine, may carry a risk of transmitting infectious agents, eg, viruses, the variant Creutzfeld-Jacob disease (vCJD) agent and, theoretically, the Creutzfeldt-Jakob disease (CJD) agent; all infections suspected by a physician possibly to have been transmitted by this product should be reported by the physician or other healthcare provider to Kedrion Biopharma Inc. at 1-855-353-7466
Drug interaction overview
- Patients who can document previous complete rabies pre-exposure prophylaxis or complete post-exposure prophylaxis and have a confirmed adequate rabies antibody titer should receive only a booster rabies vaccine (without immunoglobulin vaccine) because immunoglobulin vaccine may interfere with anamnestic response to vaccine (ACIP)
- Immunoglobulin vaccine can interfere with immune response to rabies vaccine; for this reason, do not exceed recommended dose or give additional (repeat) doses of immunoglobulin vaccine once rabies vaccination has been initiated
- immunoglobulin vaccine can inactivate rabies vaccine; for this reason, do not administer immunoglobulin vaccine in same syringe as rabies vaccine or near anatomical site of administration of the rabies vaccine
- immunoglobulin vaccine contains other antibodies that may interfere with response to live vaccines such as measles, mumps, polio or rubella; avoid immunization with live virus vaccines within 3 months after immunoglobulin vaccine administration, or in the case of measles vaccine, within 4 months after immunoglobulin vaccine administration
Pregnancy & Lactation
Pregnancy
The vaccine has not been studied in pregnant women; therefore, the risk of major birth defects and miscarriage in pregnant women who are exposed to vaccine is unknown; animal developmental or reproduction toxicity studies have not been conducted; not known whether vaccine can cause harm to fetus when administered to a pregnant woman or whether the vaccine can affect reproductive capacity
Lactation
There is no information regarding presence of vaccine in human milk, effects on breastfed infant, or on milk production; developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for vaccine and any potential adverse effects on breastfed infant from vaccine or from underlying maternal condition
Pregnancy Categories
A: Generally acceptable. Controlled studies in pregnant women show no evidence of fetal risk.
B: May be acceptable. Either animal studies show no risk but human studies not available or animal studies showed minor risks and human studies done and showed no risk. C: Use with caution if benefits outweigh risks. Animal studies show risk and human studies not available or neither animal nor human studies done. D: Use in LIFE-THREATENING emergencies when no safer drug available. Positive evidence of human fetal risk. X: Do not use in pregnancy. Risks involved outweigh potential benefits. Safer alternatives exist. NA: Information not available.Pharmacology
Mechanism of Action
Human immune globulins from donors
Pharmcokinetics
Half-life: 17.9 days
Peak plasma time: 7 days (range: 3-14 days)
Administration
Injection
Infiltrate locally around bite; inject any remaining volume IM into the upper arm deltoid region or, in small children, into the anterolateral aspect of the thigh
If IM administration is contraindicated (eg, in patients with uncorrectable bleeding disorders), administer RIG by SC injection (there are no clinical efficacy data to support SC route)
Always administer in conjunction with rabies vaccine (HDCV); however, do not administer into the same anatomical sites as rabies vaccine
Preferably give concomitantly with vaccine but may be given through 7th day after first dose of vaccine
Do not give repeated doses of RIG once rabies vaccine treatment has started, since this may interfere with the immune response to the rabies vaccine
Do not administer RIG to patients with a history of a complete pre-exposure or postexposure vaccination regimen and confirmed adequate rabies antibody titer
Do not mix with the rabies vaccine or administer in the same syringe with the rabies vaccine

(RAY-beez i-MUNE-GLOB-ue-lin)
COMMON BRAND NAME(S): Hyperrab, Imogam Rabies-HT, KedRab
USES: This medication is used to prevent a certain serious virus infection, rabies, in people who have been exposed to this virus under certain conditions (such as a bite wound or non-bite wound by an infected animal). This medication is made from healthy human blood that has high levels of certain defensive substances (antibodies) that help fight rabies infection.
HOW TO USE: Part of the dose of this medication is given by direct injection by a health care professional into the area of the wound (bite or non-bite). The remainder of your dose is given by injection into a muscle by a health care professional. It is best to receive this medication as soon as possible after exposure. If you wait too long after being exposed, the medication may not work well. Your doctor may also recommend vaccination after receiving this medication. Talk with your doctor about the best treatment for you.The dosage is based on your medical condition and weight.
SIDE EFFECTS: Redness, pain, or tenderness at the injection site may occur. Nausea, vomiting, diarrhea, dizziness, tiredness, headache, or back/joint pain may also occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.A very serious allergic reaction to this drug is rare. However, get medical help right away if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.This is not a complete list of possible side effects.
