**DOSAGE AND ADMINISTRATION** _Routine prophylactic dosage schedule:_ _Adults and children 7 years and older:_ Hyper **TET** S/D, 250 units should be given by deep intramuscular injection (see PRECAUTIONS – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_). At the same time, but in a different extremity and with a separate syringe, Tetanus and Diphtheria Toxoids Adsorbed (For Adult Use) (Td) should be administered according to the manufacturer’s package insert. Adults with uncertain histories of a complete primary vaccination series should receive a primary series using the combined Td toxoid. To ensure continued protection, booster doses of Td should be given every 10 years.2 _Children less than 7 years old:_ In small children the routine prophylactic dose of Hyper **TET** S/D may be calculated by the body weight (4.0 units/kg). However, it may be advisable to administer the entire contents of the syringe of Hyper **TET** S/D (250 units) regardless of the child’s size, since theoretically the same amount of toxin will be produced in the child’s body by the infecting tetanus organism as it will in an adult’s body. At the same time but in a different extremity and with a different syringe, Diphtheria and Tetanus Toxoids and Pertussis Vaccine Adsorbed (DTP) or Diphtheria and Tetanus Toxoids Adsorbed (For Pediatric Use) (DT), if pertussis vaccine is contraindicated, should be administered per the manufacturer’s package insert. Note: The single injection of tetanus toxoid only initiates the series for producing active immunity in the recipient. The physician must impress upon the patient the need for further toxoid injections in 1 month and 1 year. Without such, the active immunization series is incomplete. If a contraindication to using tetanus toxoid-containing preparations exists for a person who has not completed a primary series of tetanus toxoid immunization and that person has a wound that is neither clean nor minor, _only_ passive immunization should be given using tetanus immune globulin.2 See table under INDICATIONS AND USAGE – _please refer to the Product Insert/Patient Information Leaflet published on HSA for the full drug information_. Available evidence indicates that complete primary vaccination with tetanus toxoid provides long lasting protection ≥ 10 years for most recipients. Consequently, after complete primary tetanus vaccination, boosters– even for wound management–need be given only every 10 years when wounds are minor and uncontaminated. For other wounds, a booster is appropriate if the patient has not received tetanus toxoid within the preceding 5 years. Persons who have received at least two doses of tetanus toxoid rapidly develop antibodies.2 The prophylactic dosage schedule for these patients and for those with incomplete or uncertain immunity is shown on the table in INDICATIONS AND USAGE. Since tetanus is actually a local infection, proper initial wound care is of paramount importance. The use of antitoxin is adjunctive to this procedure. However, in approximately 10% of recent tetanus cases, no wound or other breach in skin or mucous membrane could be implicated.17 _Treatment of active cases of tetanus:_ Standard therapy for the treatment of active tetanus including the use of Hyper **TET** S/D must be implemented immediately. The dosage should be adjusted according to the severity of the infection.7, 8 Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever solution and container permit. They should not be used if particulate matter and/or discoloration are present. Hyper **TET** S/D is supplied with a syringe and an attached UltraSafe® Needle Guard for your protection and convenience. Please follow instructions below for proper use of syringe and UltraSafe® Needle Guard. **Directions for Syringe Usage** 1. Remove the prefilled syringe from the package. Lift syringe by barrel, not by plunger. 2. Twist the plunger rod clockwise until the threads are seated. 3. With the rubber needle shield secured on the syringe tip, push the plunger rod forward a few millimeters to break any friction seal between the rubber stopper and the glass syringe barrel. 4. Remove the needle shield and expel air bubbles. \[Do not remove the rubber needle shield to prepare the product for administration until immediately prior to the anticipated injection time.\] 5. Proceed with hypodermic needle puncture. 6. Aspirate prior to injection to confirm that the needle is not in a vein or artery. 7. Inject the medication. 8. Keeping your hands behind the needle, grasp the guard with free hand and slide forward toward needle until it is completely covered and guard clicks into place. If audible click is not heard, guard may not be completely activated. (See Diagrams A and B) 9. Place entire prefilled glass syringe with guard activated into an approved sharps container for proper disposal. (See Diagram C)  A number of factors could reduce the efficacy of this product or even result in an ill effect following its use. These include improper storage and handling of the product after it leaves our hands, diagnosis, dosage, method of administration, and biological differences in individual patients. Because of these factors it is important that this product be stored properly and that the directions be followed carefully during use. * * * **REFERENCES:** 1.
