Iodide Liquid Mixture.
Take KI every day (every 24 hours) as directed by public
officials. Do not take more than 1 dose in 24 hours. More will not help you.
Too much medicine may increase the chances of side effects.
Making a Potassium Iodide Liquid Mixture
- Put one 130 mg KI tablet into a small bowl and grind it
into a fine powder using the back of a metal teaspoon against the inside of the
bowl. The powder should not have any large pieces.
- Add 4 teaspoonfuls of water to the crushed KI powder in
the bowl and mix until the KI powder is dissolved in the water.
- Take the KI water mixture solution made in step 2 and mix
it with 4 teaspoonfuls of low fat white or chocolate milk, orange juice, flat
soda, raspberry syrup, or infant formula.
- The KI liquid mixture will keep for up to 7 days in the
refrigerator. It is recommended that the KI liquid mixture be prepared weekly.
Throw away unused portions.
The amount of KI (130 mg tablet) in the drink when mixed
as described above is 16.25 mg per teaspoonful. The number of teaspoonfuls of
the drink to give your child depends on your child's age as described in the
following table:
Child's Age |
Give your child this amount in teaspoonfuls |
Over 12 years to 18 years who weigh less than 150 pounds |
4 teaspoonfuls will give you a 65 mg dose |
Over 3 years to 12 years old |
4 teaspoonfuls will give you a 65 mg dose |
Over 1 month to 3 years old |
2 teaspoonfuls will give you a 32.5 mg dose |
Birth to 1 month |
1 teaspoonful will give you a 16.25 mg dose |
Note: This is the amount to give your child for one single
dose in teas poonfuls (not tablespoonfuls). You should give your child one dose
each day as recommended by the public officials.
Pregnant or breast feeding women, or babies under 1
month of age: Take as directed above and call a doctor as soon as possible.
Repeat dosing should be avoided. It is recommended that thyroid function be
checked in babies less than 1 month of age that take KI. Women who are pregnant
or breastfeeding should also be checked by a doctor if repeat dosing is
necessary. Although these precautions should be taken, the benefits of
short-term use of KI to block uptake of radioactive iodine by the thyroid gland
far exceed its chances of side effects.
Patients with thyroid disease: If you have both a
nodular thyroid condition such as multinodular goiter with heart disease, you
should not take KI. Patients with other thyroid conditions may take KI as
directed above, but call a doctor if you need to take KI for more than a few
days.
