Regarding Thyronorm tab. Its urgent!

Preparing for a Thyroid Scan Tell your physician about any prescription or over-the-counter medications you’re taking. Discuss how they should be used before and during the test. You may have to discontinue thyroid medication from four to six weeks before your scan. Some heart medications and any medicine containing iodine also may require adjustments. For any thyroid scan, you may be asked to avoid certain foods that contain iodine for about a week before your procedure. Typically, you shouldn’t eat: dairy productsshellfishsushikelpseaweediodized saltseasonings that contain iodized salt You also should refrain from using: antihistaminescough syrupsmultivitaminssupplements containing iodine Other drugs that could affect the results of an RAIU are: adrenocorticotropic hormone (ACTH)barbituratescorticosteroidsestrogenlithiumLugol’s solution, which contains iodinenitratesphenothiazinestolbutamide You shouldn’t have any other imaging tests that use radioactive iodine for six weeks before your thyroid scan. A few days before your procedure, your doctor may request a blood test to confirm that your thyroid function is still abnormal. Thyroid scans are used as secondary diagnostic tools to other tests, such as blood work. A scan is not typically used when thyroid functions are normal. An exception to this is when there are nodules or goiters present. You may have to fast for several hours before your exam. Food can affect the accuracy of the RAIU measurement. You’ll have to remove any jewelry or other metal accessories before the test. These may interfere with the accuracy of the scan.
