1. What Potassium Iodate 85mg Tablets are and what they are used for
Potassium Iodate is a thyroid blocking agent, and is used for example after a nuclear accident.
Potassium Iodate tablets are used at the time of a nuclear emergency; the tablets stop the thyroid gland (situated in your neck)
taking up radioactive iodine, which may be released into the environment following a nuclear accident.
Radioactive Iodine is harmful and especially dangerous to babies and children. Ask your doctor, pharmacist or emergency
co-ordinator if you need additional information especially concerning the correct use of this product.
2. What you need to know before you take Potassium Iodate 85mg Tablets
Do not take Potassium Iodate if:
% you are allergic to potassium iodate, iodine or any of the other ingredients of this medicine (listed in section 6).
Keep in mind that if you are allergic to any iodine product, then you will also be allergic to Radioactive Iodine.
This therefore means you have an additional risk that should be discussed with your doctor.
% suffer from dermatitis herpetiformis (an itchy skin disease which is associated with gluten sensitivity).
% you suffer from hypocomplementaemic vasculitis (a disease causing inflammation of the blood vessels with pain depending
on which area is involved).
% you have severe problems with your kidneys, i.e. kidney failure.
Make sure your doctor knows if you suffer from any of the above.
Warnings and precautions
Talk to your doctor before taking Potassium Iodate 85mg Tablets:
% if you have ever been treated for an overactive thyroid gland.
% if you have, or you are being treated for problems with your kidneys or adrenal glands.
% if you are suffering from dehydration or cramp due to extreme heat.
If the answer to any of these questions is YES, do not take Potassium Iodate before talking to a doctor or pharmacist.
Other medicines and Potassium Iodate 85mg Tablets
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This includes medicines
obtained without a prescription. In particular, you may not be able to use the following medicines whilst you are taking
Potassium Iodate 85mg Tablets:
% Some drugs used to treat heart problems or high blood pressure, such as quinidine or ACE inhibitors (eg. captopril or
enalapril).
% Diuretics (“water tablets”) which may affect the level of potassium in the blood such as amiloride or triamterene.
% Other drugs that may affect the thyroid, including lithium (used in the treatment of mania, bipolar disorder, and recurrent
depression) and amiodarone (used in the treatment of abnormal heart rhythms).
Pregnancy and breast-feeding
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice
before taking this medicine.
Pregnancy:
Potassium Iodate may be taken during pregnancy however the number of doses should be kept to a minimum and repeat
dosing should be avoided. You must also get medical advice since Potassium Iodate may affect the thyroid of your child and
tests from your doctor can establish and correct this.
You should not take this medicine if you are pregnant and have been diagnosed by your doctor as having an overactive thyroid
gland (a condition called hyperthyroidism).
Breast-feeding:
You should continue to breast-feed if you are taking this medicine. Repeat dosing of Potassium Iodate should be avoided if you
are breast-feeding.
Ask your doctor or pharmacist for advice before taking any medicine.
Driving and using machines

4. Possible side effects
Like all medicines, Potassium Iodate 85mg Tablets can cause side-effects, although not everybody gets them. In fact, it is taken
by the majority of patients without any problems.
The following side effects have been reported but how often they occur is unknown:
% Allergic reactions such as a rash, swollen salivary glands which are around the side of the face and neck, headache,
wheezing or coughing.
% Stomach upsets, feeling sick, disturbances of taste including a metallic taste in the mouth.
% Interference with the function of the thyroid gland which can result in either over or under activity. An over active thyroid
may cause weight loss, increased appetite and increased pulse rate. An under active thyroid may cause lethargy (loss of
energy), intolerance to cold, constipation and puffiness of the face.
% An enlargement or swelling of the thyroid gland in the neck. This may be caused by a problem with your immune system
(known as Grave’s Disease or Hashimoto’s Disease), and may also cause the symptoms of an over active thyroid gland
described above.
% Continued use of this medicine may lead to depression, nervousness, difficulty sleeping and difficulty with erections in men.
In the event of a nuclear emergency, there are other protective actions you can take against radiation damage. Emergency
assistance should be sought in order to avoid further dangerous contamination.
