Typherix

For adults and children 2 years of age and older, one dose is injected into the outer muscle of the upper arm or the thigh. A qualified health professional will inject the vaccine.

The typhoid vaccine should be given at least 14 days before entering the typhoid risk area for greatest protection from typhoid infection.

A repeat vaccination ("booster") is recommended every 3 years if you repeatedly travel to areas where you are exposed to S. typhi.

The typhoid vaccine may be given at the same time as some other vaccinations as long as they are injected into different areas of the body.

Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.

Store Typherix (Typhoid-vaccine-inactivated) in the refrigerator, do not freeze, protect it from light, and keep it out of the reach of children.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.

There may be an interaction between typhoid vaccine and any of the following:

• corticosteroids (e.g., Dexamethasone, Prednisone)
• immunosuppressants (e.g., Azathioprine, Cyclosporine, Fingolimod, hydroxychloroquine, Leflunomide, Tacrolimus)
• other live vaccines

If you are taking any of these medications, speak with your doctor or pharmacist. Depending on your specific circumstances, your doctor may want you to:

• stop taking one of the medications,
• change one of the medications to another,
• change how you are taking one or both of the medications, or
• leave everything as is.

An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.

Medications other than those listed above may interact with Typherix (Typhoid-vaccine-inactivated). Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take. Since caffeine, alcohol, the Nicotine from cigarettes, or street drugs can affect the action of many medications, you should let your prescriber know if you use them.

Before you begin using a medication, be sure to inform your doctor of any medical conditions or Allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health.
