hepatitis-a/hepatitis-b vaccine - injection, Twinrix (cont.)
HOW TO USE: Read the Vaccine Information Statement available from your health care provider before receiving the vaccine. If you have any questions, consult your health care provider.This vaccine is usually given by injection into the shoulder muscle by a health care professional. Hepatitis A/B vaccine is a slightly milky, white suspension. Before giving this medication, inspect it visually for particles or discoloration. If either is present, do not use the liquid. Shake the vial or prefilled syringe well before giving the dose. Do not dilute. Use the full recommended dose of the vaccine. Discard any remaining vaccine left in single-dose vials.A series of 3 injections is usually given over 6 months. Your doctor will give you a vaccination schedule, which must be followed closely for best effectiveness. If you have an infection with fever at the time a vaccination is scheduled, your doctor may choose to delay the injection until you are better.Dosage is based on your age. Different brands of hepatitis A/B vaccine are available for different ages and may be given differently.If you are receiving the first hepatitis A/B vaccine injection at a time when your doctor feels you may have been exposed to either hepatitis A or B, you will also receive an injection of immune globulin. Immune globulin is a dose of antibodies against the viruses and will immediately help protect you from developing an infection. These antibodies only last a few months. For long-term protection, it is important to follow your vaccination schedule exactly.
