Eugenol generic name is levothyroxine sodium tablets, subclinical hypothyroidism whether need to take levothyroxine sodium tablets, according to the patient’s age, basal state, comorbidities and other comprehensive judgment. In subclinical hypothyroidism, thyroid stimulating hormone (TSH) level is elevated in the dynamic examination of nail function, while the levels of free thyroxine (FT4) and free triiodothyronine (FT3) are normal, and other factors such as renal insufficiency are excluded. Subclinical hypothyroidism can be graded according to the TSH level, TSH <10 mIU/L is called mild subclinical hypothyroidism, TSH >10 mIU/L is called severe subclinical hypothyroidism. The current recommendations on whether subclinical hypothyroidism needs to be treated with levothyroxine sodium are as follows: 1. Non-pregnant patients with severe subclinical hypothyroidism are given levothyroxine sodium treatment, and the treatment goal is consistent with hypothyroidism. Serum TSH should be monitored during treatment to avoid overtreatment. 2. Non-pregnant patients with mild subclinical hypothyroidism may be treated with levothyroxine sodium if accompanied by symptoms of hypothyroidism, positive thyroid peroxidase antibodies (TPOAb), dyslipidemia or atherosclerotic disease. 3. The need for treatment of subclinical hypothyroidism in special populations such as pregnant women, elderly patients, children and adolescents should be determined under the guidance of a specialist. Although subclinical hypothyroidism has not reached the level of clinical hypothyroidism, some patients still need to take levothyroxine sodium tablets for supplemental treatment. If the nail function test suggests subclinical hypothyroidism, you need to go to the hospital to see a professional doctor to assess whether you need to take levothyroxine sodium tablets, to avoid delaying the treatment.
