When This Medicine Should Not Be Used:

This vaccine is not right for everyone. You should not receive it if you had an allergic reaction to influenza vaccine, or if you have an allergy to eggs.

How to Use This Medicine:

Injectable

  • The vaccine is given as a shot into a muscle or into your skin, usually in the shoulder area. The shot could be given in the thigh for babies and young children.
  • A nurse or other health provider will give you this medicine.
  • Read and follow the patient instructions that come with this medicine. Talk to your doctor or pharmacist if you have any questions.
  • A child who is younger than 9 years and who has not had a flu shot before may need 2 shots. The second shot should be given about 1 month after the first.
  • Missed dose: Most people need only 1 dose of the vaccine. If your child needs a second dose of the vaccine, it is important for him to receive the second dose on schedule.

Drugs and Foods to Avoid:

Ask your doctor or pharmacist before using any other medicine, including over-the-counter medicines, vitamins, and herbal products.

  • Tell your doctor if you are using a medicine or treatment that weakens your immune system, such as a steroid, radiation, or cancer treatment. This vaccine may not work as well if you are also using these medicines. Your doctor may still want you to get the vaccine because it can give you some protection.

  • Tell your doctor if you are pregnant or breastfeeding.
  • Tell your doctor if you ever had an unusual reaction to a flu shot, such as Guillain-Barré syndrome.
