Product Description

Product Description

Iosat Potassium Iodide has been FDA approved since 1982. Stockpiling of potassium iodide (KI) is highly recommended by health officials worldwide to prevent thyroid cancer of those exposed to radioactive iodine following a nuclear reactor accident or detonation of a nuclear weapon. Radioactive iodine can travel hundreds of miles downwind, such as it did after the Chernobyl and Fukushima disasters. The thyroid is the only part of the body that absorbs and stores iodine. By taking FDA approved potassium iodide prior to exposure of radioactive iodine, your thyroid will become saturated with safe, stable iodine. This will prevent your thyroid's absorption of any additional iodine (radioactive or not) long enough for the radioactive iodine inhaled or ingested to be safely dispersed through the kidneys.

How Potassium Iodide Works
Certain forms of iodine help your thyroid gland work right.  Most people get the iodine they need from foods like iodized salt or fish.  The thyroid can "store" or hold only a certain amount of iodine.

In a radiation emergency, radioactive iodine may be released in the air.  This material may be breathed or swallowed.  It may enter the thyroid gland and damage it.  The damage would probably not show itself for years.  Children are most likely to have thyroid damage.

If you take potassium iodide, it will fill up your thyroid gland.  This reduces the chance that harmful radioactive iodine will enter the thyroid gland.

Who Should Not Take Potassium Iodide
The only people who should not take potassium iodide are people who know they are allergic to iodide.  You may take potassium iodide even if you are taking medicines for a thyroid problem (for example, a thyroid hormone or antithyroid drug).  Pregnant and nursing women and babies and children may also take this drug.

How And When To Take Potassium Iodide
Potassium iodide should be taken as soon as possible after public health officials tell you.  You should take one dose every 24 hours.  More will not help you because the thyroid can "hold" only limited amounts of iodine.  Larger doses will increase the risk of side effects.  You will probably be told not to take the drug for more than 10 days.

Side Effects
Usually side effects of potassium iodide happen when people take higher doses for a long time.  You should be careful not to take more than the recommended dose or take it for longer than you are told.  Side effects are unlikely because of the low dose and the short time you will be taking the drug.

Possible side effects include skin rashes, swelling of the salivary glands, and "iodism" (metallic taste, burning mouth and throat, sore teeth and gums, symptoms of a head cold, and sometimes stomach upset and diarrhea).

A few people have an allergic reaction with more serious symptoms.  These could be fever and joint pains, or swelling of parts of the face or body and at times severe shortness of breath requiring immediate medical attention.

Taking iodide may rarely cause overactivity of the thyroid gland, underactivity of the thyroid gland, or enlargement of the thyroid gland (goiter).

What To Do If Side Effects Occur
If the side effects are severe or if you have an allergic reaction, stop taking potassium iodide.  Then, if possible, call a doctor or public health authority for instructions.

I like the professional way these Potassium Iodide tablets are packaged. Each packet has 14 tablets, which equals 14 adult daily doses. Each tablet is individually foil-wrapped in a packet. This is great for keeping track of how many you've taken. I have one packet for each member of the family, and if an emergency arises, it will be easy to keep track of who took his/her supplement. The packets are easy to store, and will be in better shape for a longer time than pills in a bottle.

I thought I'd post some basic information on Potassium Iodide as an emergency supplement:

The thyroid gland uptakes iodine from the bloodstream. Radioactive iodine is one of the most common of the radionuclides that may be released by nuclear fallout. If it is ingested or inhaled, the radioactive iodine will be taken up by the thyroid, greatly increasing the risk of thyroid cancer. To help avoid this, you want to saturate the body with a source of stable iodide. If the thyroid's iodine receptors are all "taken" by the non-radioactive iodide, the radioactive iodide will generally be excreted by the body.

The effectiveness of potassium iodide (KI) was proven after the 1986 Chernobyl nuclear accident. Some areas with heavy nuclear fallout after Chernobyl were NOT given potassium iodide supplements, and others were. Two decades later, studies show that the rate of thyroid cancer among populations given potassium iodide soon after the accident were the same as the rate among populations that were not affected by Chernobyl. However, populations that were affected by Chernobyl, but were not given the supplement, have shown epidemic experiences of thyroid cancer.

Note that potassium iodide cannot protect against any other causes of radiation poisoning.

Do not buy this product from SMART-CART. They sold me an expired product and tried to rub off the expiration date in an attempt to conceal this fact. Save yourself some trouble and do not support this behavior.

I've bought these pills in the past and they come like the picture shows. I ordered 4 of these and they were all out of the plastic wrap but still in the foil. On closer inspection I could see the date was erased. I can faintly see 2008 and 2010 on the pills. The buyer refunded me and said he does not sell expired products. I can would be more understanding if the dates weren't erased but this was purposefully done. I will post pictures later if I can. DO NOT BUY FROM THIS SELLER: SMART-CART!!!

Received the four packages of the IOSAT tablets ordered however there was no expiration date on any of the four packages. Contacted seller to verify where the expiration date was located but received no response. Contacted manufacturer who advised the pills may be counterfeit and they requested us to send a package to them for investigation. Have requested a refund from seller.

Especially important for children and adults over 40. From the CDC website:

Adults older than 40 years should not take KI (potassium iodide) unless public health or emergency management officials say that contamination with a VERY LARGE dose of radioactive iodine is expected. (emphasis added)

*Adults older than 40 years have the lowest chance of developing thyroid cancer or thyroid injury after contamination with radioactive iodine.

*Adults older than 40 are more likely to have allergic reactions to or adverse effects from KI.

*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.

*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.

*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.

*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.

*Infants who receive more than a single dose of KI should have their thyroid hormone levels checked and monitored by a doctor.

*AVOID REPEAT DOSING OF KI TO NEWBORNS (emphasis provided by the CDC)

*Avoid repeat dosing with KI (potassium iodide) for pregnant and breastfeeding women and newborn infants.

Using Iodine isn't without risk, even in low doses as in water treatment.

Ok, so I saw several people say their product arrived with either an expired expiration date or no expiration date at all. I still decided to order because I was ordering from a different company than they were. Well, the same exact thing happened to me. I ordered from Universal-Sales and there is no expiration date on the tablets. I even looked closely to see if it had been removed - I don't even see an erased imprint.

I emailed the company asking for a refund on the (3) packs I ordered. The company replied apologizing blaming it on their supplier. I was immediately issued a refund and told I did not have to return the tablets I have. I replied and said if they can guarantee tablets with un-expired dates printed on them that I would reorder from them. The reply I got was they could not guarantee that :/

So I would have to give a poor review for Universal-Sales' iSOAT Potassium Iodide product.

I would appreciate feedback from someone, who got un-expired tablets, about what comany they ordered from. I really want these tablets in my supplies.
