From the manufacturer's website:
Following the meltdown at Three Mile Island nuclear plant in 1979, ANBEX developed iOSAT™ for protection from an accidental or terrorist related release of radioactive iodine from a nuclear power plant or nuclear weapon.
iOSAT™ received its approval from the US Food and Drug Administration in 1982, and is the only full-strength tablet for radiation blocking which may legally be sold in the US. Only iOSAT™ has passed all FDA tests for purity, quality, safety and efficacy.Information from the CDC
What is Potassium Iodide (KI)?
Potassium iodide (also called KI) is a salt of stable (not
radioactive) iodine. Stable iodine is an important chemical needed by
the body to make thyroid hormones. Most of the stable iodine in our
bodies comes from the food we eat. KI is stable iodine in a medicine
form. This fact sheet from the Centers for Disease Control and
Prevention (CDC) gives you some basic information about KI. It explains
what you should think about before you or a family member takes KI.
What does KI do?
Following a radiological or nuclear event, radioactive iodine may be
released into the air and then be breathed into the lungs. Radioactive
iodine may also contaminate the local food supply and get into the
body through food or through drink. When radioactive materials get into
the body through breathing, eating, or drinking, we say that “internal contamination”
has occurred. In the case of internal contamination with radioactive
iodine, the thyroid gland quickly absorbs this chemical. Radioactive
iodine absorbed by the thyroid can then injure the gland. Because
non-radioactive KI acts to block radioactive iodine from being taken
into the thyroid gland, it can help protect this gland from injury.
What KI cannot do
Knowing what KI cannot do is also important. KI cannot prevent
radioactive iodine from entering the body. KI can protect only the
thyroid from radioactive iodine, not other parts of the body. KI cannot
reverse the health effects caused by radioactive iodine once damage to
the thyroid has occurred. KI cannot protect the body from radioactive
elements other than radioactive iodine—if radioactive iodine is not
present, taking KI is not protective.
How does KI work?
The thyroid gland cannot tell the difference between stable and
radioactive iodine and will absorb both. KI works by blocking
radioactive iodine from entering the thyroid. When a person takes KI,
the stable iodine in the medicine gets absorbed by the thyroid. Because
KI contains so much stable iodine, the thyroid gland becomes “full”
and cannot absorb any more iodine—either stable or radioactive—for the
next 24 hours.
Iodized table salt also contains iodine; iodized table salt contains
enough iodine to keep most people healthy under normal conditions.
However, table salt does not contain enough iodine to block radioactive
iodine from getting into your thyroid gland. You should not use table salt as a substitute for KI.
How well does KI work?
Knowing that KI may not give a person 100% protection against
radioactive iodine is important. How well KI blocks radioactive iodine
- how much time passes between contamination with radioactive iodine and the taking of KI (the sooner a person takes KI, the
- how fast KI is absorbed into the blood, and
- the total amount of radioactive iodine to which a person is exposed.
Who should take KI?
The thyroid glands of a fetus and of an infant are most at risk of
injury from radioactive iodine. Young children and people with low
stores of iodine in their thyroid are also at risk of thyroid injury.
Infants (including breast-fed infants): Infants need to be given the recommended dosage of KI for babies (see How much KI should I take?).
The amount of KI that gets into breast milk is not enough to protect
breast-fed infants from exposure to radioactive iodine. The proper dose
of KI given to a nursing infant will help protect it from radioactive
iodine that it breathes in or drinks in breast milk.
Children: The United States Food and Drug
Administration (FDA) recommends that all children internally
contaminated with (or likely to be internally contaminated with)
radioactive iodine take KI, unless they have known allergies to iodine.
Children from newborn to 18 years of age are the most sensitive to the
potentially harmful effects of radioactive iodine.
Young Adults: The FDA recommends that young adults
(between the ages of 18 and 40 years) internally contaminated with (or
likely to be internally contaminated with) radioactive iodine take the
recommended dose of KI. Young adults are less sensitive to the effects
of radioactive iodine than are children.
Pregnant Women: Because all forms of iodine cross
the placenta, pregnant women should take KI to protect the growing
fetus. However, pregnant women should take only one dose of KI
following internal contamination with (or likely internal contamination
with) radioactive iodine.
Breastfeeding Women: Women who are breastfeeding
should take only one dose of KI if they have been internally
contaminated with (or are likely to be internally contaminated with)
radioactive iodine. Because radioactive iodine quickly gets into breast
milk, CDC recommends that women internally contaminated with (or are
likely to be internally contaminated with) radioactive iodine stop
breastfeeding and feed their child baby formula or other food if it is
available. If breast milk is the only food available for an infant,
nursing should continue.
Adults: Adults older than 40 years should not take
KI unless public health or emergency management officials say that
contamination with a very large dose of radioactive iodine is expected.
Adults older than 40 years have the lowest chance of developing
thyroid cancer or thyroid injury after contamination with radioactive
iodine. They also have a greater chance of having allergic reactions to
When should I take KI?
The primary protective measures after a radiologic or nuclear event
are sheltering or evacuation. Local public health or emergency
management officials will tell the public if KI or other protective
actions are needed. For example, public health officials may advise you
to remain in your home, school, or place of work (this is known as
“shelter-in-place”) or to evacuate. You may also be told not to eat
some foods and not to drink some beverages until a safe supply can be
brought in from outside the affected area. Following the instructions
given to you by these authorities can lower the amount of radioactive
iodine that enters your body and lower the risk of serious injury to
your thyroid gland.
How much KI should I take?
The FDA has approved two different forms of KI—tablets and
liquid—that people can take by mouth after a nuclear radiation
emergency. Tablets come in two strengths, 130 milligram (mg) and 65 mg.
The tablets are scored so they may be cut into smaller pieces for
lower doses. Each milliliter (mL) of the oral liquid solution contains
65 mg of KI.
According to the FDA, the following doses are appropriate to take after
internal contamination with (or likely internal contamination with)
- Adults should take 130 mg (one 130 mg tablet OR two 65 mg tablets OR two mL of solution).
- Women who are breastfeeding should take the adult dose of 130 mg.
- Children between 3 and 18 years of age should take 65 mg (one 65 mg tablet OR 1 mL of solution). Children who are adult size
(greater than or equal to 150 pounds) should take the full adult dose, regardless of their age.
- Infants and children between 1 month and 3 years of age should take 32 mg (½ of a 65 mg tablet OR ½ mL of
solution). This dose is for both nursing and non-nursing infants and children.
- Newborns from birth to 1 month of age should be given 16 mg (¼ of a 65 mg tablet or ¼ mL of solution). This
dose is for both nursing and non-nursing newborn infants.
How often should I take KI?
A single dose of KI protects the thyroid gland for 24 hours. A
one-time dose at the levels recommended in this fact sheet is usually
all that is needed to protect the thyroid gland. In some cases,
radioactive iodine might be in the environment for more than 24 hours.
If that happens, local emergency management or public health officials
may tell you to take one dose of KI every 24 hours for a few days. You
should do this only on the advice of emergency management officials,
public health officials, or your doctor. Avoid repeat dosing with KI
for pregnant and breastfeeding women and newborn infants. Those
individuals may need to be evacuated until levels of radioactive iodine
in the environment fall.
Taking a higher dose of KI, or taking KI more often than
recommended, does not offer more protection and can cause severe illness
Medical conditions that may make it harmful to take KI
Taking KI may be harmful for some people because of the high levels of iodine in this medicine. You should not take KI if
• you know you are allergic to iodine (If you are unsure about this,
consult your doctor. A seafood or shellfish allergy does not
necessarily mean that you are allergic to iodine.) or
• you have certain skin disorders (such as dermatitis herpetiformis or urticaria vasculitis).
People with thyroid disease (for example, multinodular goiter,
Graves’ disease, or autoimmune thyroiditis) may be treated with KI.
This should happen under careful supervision of a doctor, especially if
dosing lasts for more than a few days.
In all cases, talk to your doctor if you are not sure whether to take KI.
What are the possible risks and side effects of KI?
When public health or emergency management officials tell the public
to take KI following a radiologic or nuclear event, the benefits of
taking this drug outweigh the risks. This is true for all age groups.
Some general side effects caused by KI may include intestinal upset,
allergic reactions (possibly severe), rashes, and inflammation of the
When taken as recommended, KI causes only rare adverse health
effects that specifically involve the thyroid gland. In general, you are
more likely to have an adverse health effect involving the thyroid
gland if you
- take a higher than recommended dose of KI,
- take the drug for several days, or
- have pre-existing thyroid disease.
Newborn infants (less than 1 month old) who receive more than one
dose of KI are at particular risk for developing a condition known as
hypothyroidism (thyroid hormone levels that are too low). If not
treated, hypothyroidism can cause brain damage. Infants who receive KI
should have their thyroid hormone levels checked and monitored by a
doctor. Avoid repeat dosing of KI to newborns.
Where can I get KI?
KI is available without a prescription. You should talk to your
pharmacist to get KI and for directions about how to take it correctly.
Your pharmacist can sell you KI brands that have been approved by the
