Anti-Tetanus immunoglobulin


Safe substance and/or breastfeeding is the best option.

Immunoglobulins (Ig) are proteins produced by B lymphocytes as a humoral response to antigens foreign to the body itself. The immunoglobulins used in clinical practice are preparations from human serum or plasma that contain antibodies, mainly IgG. 

Human tetanus immunoglobulin mainly contains immunoglobulin G (IgG) with a high content of specific antibodies against the toxin of Clostridium tetani. It is obtained from plasma or serum of adult human donors who have been immunised with tetanus vaccine.

Its very high molecular weight make it highly unlikely that significant quantities will pass into breast milk. Administration of standard immunoglobulin does not significantly alter the levels of immunoglobulins (IgG or IgM) in colostrum or breast milk. (Palmeira 2009)

Expert authors consider the use of this medication safe during breastfeeding. (LactMed, Briggs 2015)

We do not have alternatives for Anti-Tetanus immunoglobulin since it is relatively safe.

Suggestions made at e-lactancia are done by APILAM team of health professionals, and are based on updated scientific publications. It is not intended to replace the relationship you have with your doctor but to compound it. The pharmaceutical industry contraindicates breastfeeding, mistakenly and without scientific reasons, in most of the drug data sheets.

Jose Maria Paricio, Founder & President of APILAM/e-Lactancia

Your contribution is essential for this service to continue to exist. We need the generosity of people like you who believe in the benefits of breastfeeding.

Thank you for helping to protect and promote breastfeeding.
