Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the national reporting system: After taking ThySat babies under the age of 3 months should be taken to see their doctor assoon as possible so that their thyroid functioncan be closely monitored. No dosage adjustments are required in special populations such as patients with impaired renal or hepatic function. Iodine elimination occurs mainly via the kidneys; however, renal elimination rate is not influenced by iodine intake or iodine serum levels.

Women in the last 3 months of pregnancy should inform their doctor and other healthcareprofessionals that they have taken ThySat, as ablood sample from the umbilical cord should betaken to measure the baby's thyroid function. Only take potassium iodide if state or local health authorities suggest you do so. During an emergency, health officials will send out an announcement. Your health department will then tell you when it’s OK to take potassium iodide. They’ll also tell you when you can stop the medication.Potassium salts should be given cautiously to patients with renal or adrenal insufficiency, acute dehydration or heat cramp.

In case of prolonged exposure, repeat dosing may be necessary although if you are pregnantor breastfeeding you should normally not takemore than two doses. You must also get medicaladvice since ThySat may affect the thyroidof your child and tests from your doctor canestablish and correct this. Babies up to a monthold should only receive one dose and shouldhave their thyroid function assessed by theirdoctor. ThySat is taken by the majority of patients without any problems. However, like manyother medicines, it may occasionally cause sideeffects in some people. These may include: In overdose, symptoms of iodism such as headache, pain and swelling of the salivary glands, fever or laryngitis, swelling or inflammation of the throat, gastrointestinal upset and diarrhoea can occur. Pulmonary oedema can also occur. In children of 3 to 12 years 50% of the adult dose should be given and in children of 1 month to 3 years the dose should be 25% of the adult dose. But the salt doesn’t protect the rest of your body from radioactive iodine, only your thyroid. It also can’t reverse any health issues caused by radioactive iodine if your thyroid was already damaged.

Hyperthyroidism, iodine induced autoimmunity (Grave's and Hashimoto type), toxic nodular goitre and iodine-induced hypothyroidism have been reported as side effects of iodine therapy. Patients with thyrotoxicosis treated medically, or patients with a past history of thyrotoxicosis treated medically who are now off treatment and apparently in remission, may be at risk.
