This vaccine is used to help prevent infection (typhoid fever) caused by a certain bacteria (Salmonella typhi). People can get this infection by eating contaminated food or drinking contaminated water. This vaccine is recommended for people older than 6 years who are traveling to areas where typhoid fever is common (such as countries in Central and South America, Africa, Asia), who are exposed to someone with persistent typhoid infection, or who work with the bacteria in a laboratory.
Typhoid vaccine contains live bacteria that have been weakened. It works by causing the body to produce its own protection (antibodies) against the bacteria that cause typhoid fever.
Before taking each dose, inspect the foil blister pack to make sure it is completely sealed. Carefully open the blister pack and inspect the capsule to make sure it is not damaged. Consult your pharmacist if the foil blister pack or capsule is damaged.
Take this medication by mouth without food, usually every other day for 4 doses or as directed by your doctor. Swallow the capsule whole with cold or barely warm liquid about 1 hour before a meal. Place the capsule in your mouth and swallow with the liquid right away. Do not chew, crush, or hold the capsule in your mouth.
Follow the dosing schedule closely for the vaccine to be most effective. To help you remember, mark your calendar to keep track of when to take your next dose. You should complete your course of the vaccine at least 1 week before possible exposure to typhoid fever.
You may need a booster vaccine if you still remain at risk for typhoid fever after 5 years. Ask your doctor or pharmacist for more details.
Nausea may occur. If this effect persists or worsens, tell your doctor or pharmacist promptly.
