"July 13, 2015 -- Pyrethroids are chemicals commonly used in products aimed at killing insects, head lice, and fleas on pets. They were created to replace now-banned chemicals in insecticides and other products.
But new research is raising "...
BayTet is made from human plasma. Products made from human plasma may contain infectious agents, such as viruses, that can cause disease. The risk that such products will transmit an infectious agent has been reduced by screening plasma donors for prior exposure to certain viruses, by testing for the presence of certain current virus infections, and by inactivating and/or removing certain viruses. Despite these measures, such products can still potentially transmit disease. There is also the possibility that unknown infectious agents may be present in such products. Individuals who receive infusions of blood or plasma products may develop signs and/or symptoms of some viral infections, particularly hepatitis C. ALL infections thought by a physician possibly to have been transmitted by this product should be reported by the physician or other healthcare provider to Bayer Corporation [1-800-288-8371].
The physician should discuss the risks and benefits of this product with the patient, before prescribing or administering it to the patient.
BayTet (tetanus immune globulin (human) solvent/detergent treated 250 units) should be given with caution to patients with a history of prior systemic allergic reactions following the administration of human immunoglobulin preparations.
In patients who have severe thrombocytopenia or any coagulation disorder that would contraindicate intramuscular injections, BayTet (tetanus immune globulin (human) solvent/detergent treated 250 units) should be given only if the expected benefits outweigh the risks.
BayTet (tetanus immune globulin (human) solvent/detergent treated 250 units) should not be given intravenously. Intravenous injection of immunoglobulin intended for intramuscular use can, on occasion, cause a precipitous fall in blood pressure, and a picture not unlike anaphylaxis. Injections should only be made intramuscularly and care should be taken to draw back on the plunger of the syringe before injection in order to be certain that the needle is not in a blood vessel. Intramuscular injections are preferably administered in the anterolateral aspects of the upper thigh and the deltoid muscle of the upper arm. The gluteal region should not be used routinely as an injection site because of the risk of injury to the sciatic nerve. If the gluteal region is used, the central region MUST be avoided; only the upper, outer quadrant should be used.16
Chemoprophylaxis against tetanus is neither practical nor useful in managing wounds. Wound cleaning, debridement when indicated, and proper immunization are important. The need for tetanus toxoid (active immunization), with or without TIG (passive immunization), depends on both the condition of the wound and the patient's vaccination history. Rarely has tetanus occurred among persons with documentation of having received a primary series of toxoid injections.2 See table under INDICATIONS.
Skin tests should not be done. The intradermal injection of concentrated IgG solutions often causes a localized area of inflammation which can be misinterpreted as a positive allergic reaction. In actuality, this does not represent an allergy; rather, it is localized tissue irritation. Misinterpretation of the results of such tests can lead the physician to withhold needed human antitoxin from a patient who is not actually allergic to this material. True allergic responses to human IgG given in the prescribed intramuscular manner are rare. Although systemic reactions to human immunoglobulin preparations are rare, epinephrine should be available for treatment of acute anaphylactic reactions.
Pregnancy Category C
Animal reproduction studies have not been conducted with BayTet (tetanus immune globulin (human) solvent/detergent treated 250 units) . It is also not known whether BayTet (tetanus immune globulin (human) solvent/detergent treated 250 units) can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. BayTet (tetanus immune globulin (human) solvent/detergent treated 250 units) should be given to a pregnant woman only if clearly needed.
Safety and effectiveness in the pediatric population have not been established.
