- BCG vaccine live
rabies immune globulin, human (RIG) decreases effects of BCG vaccine live by Other (see comment). Use Caution/Monitor. Comment: High dose rabies immunoglobulin may impair response to active immunization.
- efgartigimod alfa
efgartigimod alfa will decrease the level or effect of rabies immune globulin, human (RIG) by receptor binding competition. Use Caution/Monitor. Coadministration of efgartigimod with medications that bind to the human neonatal Fc receptor may lower systemic exposures and effectiveness of such medications. Closely monitor for reduced effectiveness of medications that bind to the human neonatal Fc receptor. If long-term use of such medications is essential, consider discontinuing efgartigimod and using alternative therapies.

Warnings
Contraindications
None
Cautions
Patients who can document previous complete rabies pre-exposure prophylaxis or complete postexposure prophylaxis should only receive a booster rabies vaccine without RIG, owing to RIG interference with anamnestic response to the vaccine
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
Caution with prior allergic reactions to immune globulins (RIG contains small quantity of IgA)
Avoid immunization with measles vaccine within 4 months after RIG; avoid other live attenuated vaccines for 3 months
Do NOT give IV; do not inject into a blood vessel because of the risk of severe allergic or hypersensitivity reaction, including decreased blood pressure and anaphylactic shock
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)
RIG is derived from human plasma; therefore, the potential exists for viral transmission (eg, CJD)
Pregnancy & Lactation
Pregnancy
Has not been studied in pregnant women
Animal and reproductive studies have not been conducted
Lactation
Unknown if excreted in human milk
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

RABIES IMMUNE GLOBULIN - INJECTION
(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. If you notice other effects not listed above, contact your doctor or pharmacist promptly.In the US -Call your doctor for medical advice about side effects. You may report side effects to FDA at 1-800-FDA-1088 or at www.fda.gov/medwatch.In Canada - Call your doctor for medical advice about side effects. You may report side effects to Health Canada at 1-866-234-2345.
PRECAUTIONS: Before receiving rabies immune globulin, tell your doctor or pharmacist if you are allergic to it; or to other immune globulin products; or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.Before using this medication, tell your doctor or pharmacist your medical history, especially of: a certain immune system problem (immunoglobulin A deficiency).This drug may make you dizzy. Alcohol or marijuana (cannabis) can make you more dizzy. Do not drive, use machinery, or do anything that needs alertness until you can do it safely. Limit alcoholic beverages. Talk to your doctor if you are using marijuana (cannabis).This medication is made from human blood. Even though the blood is carefully tested, and this medication goes through a special manufacturing process, there is an extremely small chance that you may get infections (such as Creutzfeldt-Jakob disease-CJD) from the medication. Consult your doctor or pharmacist for more information.Tell your doctor of any recent or planned immunizations/vaccinations. This medication may prevent a good response to certain live viral vaccines (such as measles, mumps, rubella, varicella). If you have recently received any of these vaccines, your doctor may have you tested for a response or have you vaccinated again later. If you plan on getting any of these vaccines, your doctor will instruct you about the best time to receive them so you get a good response.Before having surgery, tell your doctor or dentist about all the products you use (including prescription drugs, nonprescription drugs, and herbal products).During pregnancy, this medication should be used only when clearly needed. Discuss the risks and benefits with your doctor.It is unknown if this drug passes into breast milk. Consult your doctor before breast-feeding.
