1. What is Dukoral and what is it used for

Dukoral is an oral cholera vaccine that stimulates the intestinal immune defenses. The vaccine protects adults and children from 2 years of age against cholera.

Dukoral makes the body produce its own protection against cholera. After receiving the vaccine, the body will create substances called antibodies that fight the toxin and cholera bacteria that cause diarrhea.

2. What you need to know before you start using Dukoral

Do not use Dukoral

? if you are allergic to any of the components of the vaccine (listed in section 6) or to formaldehyde.

? if you have an acute gastric disorder or an infection accompanied by fever (vaccination should be postponed).

Warnings and precautions

Talk to your doctor before starting to take Dukoral

? if you are receiving treatment that affects your immune system

? if you have an immune system disease (including HIV infection).

The vaccine may provide a lower level of protection than that which occurs in people without immune system impairment.

The vaccine does not provide complete protection and it is important to follow dietary and hygiene recommendations to avoid contracting diseases that cause diarrhea.

Children

Do not administer this vaccine to children under 2 years of age as protection has not been studied in this group.

3. How to use Dukoral

Follow the instructions for administration of the medicine contained in this leaflet or as indicated by your doctor. In case of doubt, consult your doctor again.

Adults and children from 6 years of age:The primary vaccination consists of two doses orally (by mouth) separated by a minimum interval of one week (up to six weeks).

• Take the first dose no later than two weeks before starting your trip.
• Take the second dose at least one week after the first dose and at least one week before your trip.

It takes approximately one week for protection to begin after the last dose.

To achieve continued protection, revaccination is recommended after two years. If it has been less than two years since your last dose of the vaccine, a single dose will renew your protection. If it has been more than two years since your last dose of the vaccine, primary vaccination should be repeated (2 doses).

Children from 2 to less than 6 years of age:The primary vaccination consists of three doses taken orally (by mouth) separated by a minimum interval of one week (up to six weeks). Only half of the buffer solution should be mixed with the vaccine.

• Administer the first dose to the child no later than three weeks before starting your trip.
• Administer the second dose to the child at least one week after the first dose.

If it has been less than six months since the last dose of the vaccine, a single dose will renew protection. If it has been more than six months since the last vaccination, primary vaccination should be repeated (3 doses).

The suspension is a white suspension that is supplied in a glass vial for single dose. Each vial comes with a sachet containing a white, effervescent granule of sodium bicarbonate. The effervescent granule should be dissolved in a glass of cold water, and the resulting buffer solution should be mixed with the suspension.
