Thyroid peroxidase antibodies are high, but thyroid function is normal, there may be no need for treatment at present, no antibiotics, and regular rechecks are sufficient. Elevated thyroid peroxidase antibodies alone do not require medication. Generally, this increase indicates an autoimmune disease, such as Hashimoto’s thyroiditis. Thyroid function needs to be monitored regularly. As long as the thyroid function is normal, no special treatment is needed. Antibiotics are indicated for inflammation caused by infection and should not be used to treat thyroid disease. If a patient with high thyroid peroxidase antibodies and normal thyroid function develops an infection, antibiotics can be used to treat the infection and generally have no effect on the body. It is recommended that patients should seek timely medical treatment when they are unwell. Avoid self-medication leading to adverse consequences.
