HAVRIX 1440 INJ

The Hepatitis A Vaccine works by stimulating the body's immune system to produce antibodies against the Hepatitis A virus. It contains inactivated (killed) hepatitis A virus, which is unable to cause disease but is sufficient to trigger an immune response. When the vaccine is administered, the immune system recognizes the viral particles as foreign antigens. This prompts the production of antibodies specifically designed to neutralize the hepatitis A virus. These antibodies remain in the body, providing protection against future exposure to the live virus. The vaccine essentially teaches the immune system to identify and destroy the hepatitis A virus, thereby preventing it from causing hepatitis A infection.

The following are the uses of Hepatitis A Vaccine Injection:

• Used for preventing Hepatitis A, a liver infection caused by the Hepatitis A virus.
• Used for travelers to regions with high Hepatitis A prevalence.
• Used for individuals with chronic liver disease to prevent further complications.
• Used for close contacts of Hepatitis A patients to prevent the spread.
• Used for children and adolescents as part of routine immunization schedules.
• Used for healthcare workers and food handlers to reduce occupational risk.
• Used for post-exposure prophylaxis within 2 weeks of contact with the virus.

In the case of an overdose of Hepatitis A Vaccine Injection, it is important to note that adverse effects are not expected. However, if multiple doses are administered inadvertently, there is a potential for increased local reactions at the injection site, such as redness, swelling, or pain. It is advisable to monitor for any unusual symptoms and consult a healthcare professional for guidance if any concerns arise following an overdose of this vaccine. Prompt medical advice can help address any potential side effects and ensure appropriate management.

In the case of a missed dose of Hepatitis A Vaccine Injection, it is important to consult your healthcare provider for guidance. They will determine the appropriate course of action based on the timing of the missed dose and your individual health status. Generally, if a dose is missed, it can be administered as soon as possible, and the vaccination schedule can be adjusted accordingly. It is crucial to complete the full vaccination series to ensure optimal protection against Hepatitis A.

To administer the Hepatitis A Vaccine, clean the injection site with an alcohol swab, insert the needle into the muscle, typically in the upper arm, and inject the vaccine intramuscularly, following the recommended dosage for your age group as prescribed by the healthcare provider.

Following are the conditions/situations when Hepatitis A Vaccine Injection should not be administered:

• Not recommended for individuals with a severe allergic reaction history to any component of the vaccine or a previous dose of Hepatitis A vaccine.
• Contraindicated in individuals with a weakened immune system due to certain medical conditions or medications.
• Not suitable for people with a moderate or severe acute illness. It is advisable to wait until the illness has resolved before vaccination.
• Should not be administered to individuals with a history of hypersensitivity or severe reaction to other vaccines.
• Not recommended for infants below one year of age, as the vaccine's effectiveness in this age group has not been established.
• Should be avoided in individuals with a history of thrombocytopenia (low platelet count) after previous Hepatitis A vaccination.
• Not suitable for individuals with a current or recent (within 6-12 months) acute hepatitis infection.

The side effects of Hepatitis A Vaccine Injection may include:

• Mild fever
• Headache
• Fatigue
• Loss of appetite

• Vaccination should be delayed in individuals with acute severe febrile illness, but mild infections are not a contraindication.
• Precautions are necessary for individuals with bleeding disorders or those on anticoagulant therapy, as injection site bleeding may occur.
• Individuals with a history of immune system disorders or those receiving immunosuppressive therapy should consult a healthcare professional before vaccination.
• Pregnant women should only receive the vaccine if clearly needed, and breastfeeding women should exercise caution.
• The vaccine is not a substitute for taking usual precautions to avoid hepatitis A infection.

Following are the drug interactions for Hepatitis A Vaccine Injection:

• Administration with other live vaccines should be avoided due to potential interference and reduced immune response.
• Drugs that suppress the immune system may reduce the efficacy of the vaccine.
• These medications can potentially interfere with the vaccine's effectiveness.
• Administration of the vaccine should be timed carefully if the patient has received blood products containing antibodies.
• If given concurrently, Hepatitis A vaccine should be administered at a different injection site to minimize potential interference.
• Some medications in these classes may decrease the immune response to the vaccine.
• Radiation treatment can affect the immune system, potentially reducing vaccine effectiveness.

Following are the food interactions for Hepatitis A Vaccine Injection:

• No specific food interactions are known for the Hepatitis A Vaccine. You can generally maintain your regular diet after vaccination.
• Staying well-hydrated and eating a balanced diet can support your immune system's response to the vaccine.
