Although thyroid cancer is a relatively inert malignant tumor, it is after all a malignant disease, and surgery is only the first and certainly the most important step in its treatment. Post-operative standardized treatment and follow-up are more important, he can effectively inhibit the recurrence of tumor and improve the quality of life. 1. Eugenol should be taken orally daily. 2. Missed dose: If you miss one dose, you can take twice the dose on the next day. If you miss more than one day, you should insist on taking twice the dose for more than one day until you make up for the missed dose. 3, time: take 1 hour before breakfast, 3 hours after dinner (before bedtime), half an hour before breakfast, three kinds of taking time absorption efficiency is reduced in turn, half an hour before breakfast is the bottom line to adhere to. 4.Blood draw: ask for blood check on an empty stomach and take the medicine after the check. 5, review cycle: after surgery oral eugenol patients need to review the nail function in the 6th week, thereafter, within 1 year after surgery, generally 3-6 months to review once, 1 year after surgery, can be 6 months to review once. It is important to note that whenever there is a change in the dose of medication, etc., it is necessary to wait 6 weeks for a review, at least 4 weeks. The reason is that the half-life of Eugenol is 7 days. 6. Affects absorption: Take with water only. Some special drugs or foods should be taken after sufficient time interval: 1 hour interval with vitamins, hypertension drugs, tonic; 2 hours interval with food or drugs containing iron, calcium
4 hours between doses of milk and legumes; 12 hours between doses of cholestyramine or lipid-lowering resins. Note: (1) Eugenol is absorbed in the small intestine; (2) The acidic pH value in the stomach in the fasting state is more important for the absorption of tablets in the small intestine, so it is important to assess the function of the gastrointestinal tract, such as HP-related gastritis, atrophic gastritis, fatty leaking, etc., by taking more medication than the expected dose. After the disease is cured, thyroid function and levothyroxine dose need to be re-evaluated; (3) the best absorption of the drug 70-80%; (4) eating affects absorption; (5) fiber, grape juice is currently not found to affect absorption; (6) soy products affect absorption; coffee affects absorption. 7, eugenol dose in the end is enough, should be subject to the final blood check. 8, eugenol and human secretion of thyroxine molecular formula is the same, the vast majority of patients can tolerate. Very few patients have symptoms such as “headache, palpitations, anxiety”, but the patient’s thyroid function may be normal, please consult your doctor, there are ways to relieve or even eliminate the symptoms. 9. Side effects of overdose: atrial fibrillation, osteoporosis; insufficient dose affects lipid metabolism and cardiovascular disease progression. Please consult your physician, taking medication should be individualized. 10.Replacement to other products, such as Retis, also levothyroxine sodium tablets, requires re-evaluation of TSH levels. 11.The dose of medication before and during pregnancy needs to be adjusted according to TSH level in time, please consult your physician. 12. If the thyroid gland has been completely excised and iodine release therapy is required after surgery, you cannot take or need to stop taking Eugenol before. There are two reasons for this: TSH is suppressed after taking the drug, which affects the absorption of iodine; thyroxine tablets themselves are iodine-containing drugs.
