Some doctors or patients like to remember how many tablets they take a day without remembering the dose. When the patient buys the medicine at the pharmacy or prescribes it at other hospitals, he or she may get a different dose of tablets than the original one and then take the original number of pellets, resulting in an increase or decrease in the amount of medication taken, followed by abnormal thyroid function or a failure of TSH to meet treatment requirements. Therefore, it is recommended that patients must remember how many μg per day they are taking Eugenol, and must know how many μg per pill you are currently taking, so that you can avoid mistakes and actually take the medication as prescribed to achieve your treatment goals.
