This page contains brief details about the drug , it's indication, dosage & administaration, mechanism of action, related brands with strength, warnings and common side effects.

Background and Date of Approval

Anti-Rh(D) immunoglobulin belongs to the therapeutic class of immune globulins.

Mechanism of Action of undefined

Anti-Rh(D) immunoglobulin involves binding Rh Ig antibodies to Rh-positive fetal blood cells that enter the maternal bloodstream during pregnancy or childbirth. By covering the Rh(D) antigens on these fetal blood cells, RhIg prevents the mother's immune system from recognizing them as foreign and producing antibodies against them. This neutralization of Rh-positive fetal blood cells effectively prevents Rh sensitization, ensuring the mother's immune system does not develop antibodies that could lead to hemolytic disease of the newborn (HDN) in subsequent pregnancies.

Uses of undefined

Anti-Rh(D) immunoglobulin primarily prevents Rh sensitization in Rh-negative individuals, particularly pregnant women. It is administered during pregnancy and after childbirth to neutralize any Rh-positive fetal blood cells that may have entered the maternal bloodstream. Additionally, RhIg is employed in situations like miscarriages, ectopic pregnancies, invasive prenatal procedures, and Rh-incompatible blood transfusions or organ transplants to prevent the development of Rh antibodies, safeguarding against the potential complications of Rh sensitization in subsequent pregnancies or medical scenarios.

undefined Drug administaration and Dosage available

Anti-Rh(D) immunoglobulin (RhIg) can be administered through two primary routes: intramuscular (IM) injection and intravenous (IV) injection. The doctor chooses the administration route based on the patient's needs and preferences.

Warnings, Precautions and Side Effects of undefined


Anti-Rh(D) immunoglobulin can potentially trigger severe allergic reactions, including anaphylaxis, although such reactions are rare. Rare cases of blood clots (thromboembolism) have been reported with the use of this medication. There is still a very low risk of transmitting infectious agents through its use.


Healthcare providers should be prepared to manage allergic reactions and have appropriate emergency measures when administering Anti-Rh(D) immunoglobulin. Patients with a history of clotting disorders or conditions that increase the risk of clot formation need careful monitoring before taking this medication. Patients should be aware of the minimal risk of transmitting infectious agents through its use.

Side Effects

Side effects of anti-Rh(D) immunoglobulin are generally rare but can include mild local reactions at the injection site, such as pain, redness, or swelling. Some individuals may experience a low-grade fever. Serious side effects, while extremely uncommon, may include severe allergic reactions (anaphylaxis), blood clots (thromboembolism), kidney issues, and the possibility of infection transmission, although this risk is minimal.

Word Of Advice

When using anti-Rh(D) immunoglobulin, healthcare providers should exercise precautions such as confirming the patient's Rh blood type, monitoring for allergic reactions (especially in those with known allergies), assessing clotting risk, closely observing patients with kidney issues, educating about infection transmission risks, considering vaccination timing, evaluating safety during pregnancy and breastfeeding, screening for hepatitis B, administering accurate dosages, being aware of potential drug interactions, ensuring proper storage, monitoring for Rh sensitization efficacy, adjusting dosages for pediatric and geriatric patients, and assessing patients with compromised immune systems or underlying conditions. These precautions help ensure the safe and effective use of this medication for each patient's specific clinical needs while minimizing potential risks.
