The primary medications for treating hyperthyroidism are propylthiouracil and methimazole. Both drugs have similar side effects, and long-term use requires attention to the following aspects:1. Impact on white blood cells. Thyroid medications require regular blood tests as both drugs can cause a decrease in white blood cells and platelets, potentially leading to agranulocytosis in severe cases.2. Liver function damage. Both oral medications can cause liver damage, resulting in elevated liver enzymes. If liver enzymes exceed 2.5 times the normal level, the medication should be discontinued. If below 2.5 times, liver-protective treatment can continue.3. Allergic rashes. Approximately 5-10% of patients may develop allergic rashes after taking the medication, and some patients may experience autoimmune diseases such as ANCA-associated vasculitis.Therefore, patients with hyperthyroidism should regularly monitor liver function and blood tests to prevent adverse effects of the medication.
Common symptoms include fever, fatigue, and discomfort in the affected area. Always consult with a healthcare professional for an accurate diagnosis.
Diagnosis typically involves a physical examination, medical history review, and possibly laboratory tests or imaging studies depending on the suspected cause.
Treatment options vary based on the specific condition, severity, and individual health factors. They may include medication, lifestyle changes, physical therapy, or in some cases, surgical intervention.
Seek immediate medical attention if you experience severe symptoms, rapid worsening of condition, or if self-care measures aren't providing relief within a reasonable timeframe.
