What should be done if an adult's fever does not subside after taking fever-reducing medication?

  Fever reduction refers to antipyresis. There are many reasons why adults may not experience fever relief after taking antipyretic medication. Using antipyretics alone may yield limited effectiveness; it's important to identify the underlying cause and follow medical advice to combine appropriate medications accordingly. Common causes include viral colds, pharyngitis, tonsillitis, tuberculosis, and hyperthyroidism.

  1. Viral Cold

  A cold caused by a viral infection leads to extensive viral replication in the body, which can affect the body's temperature regulation center and result in fever. Symptoms may include sore throat and nasal congestion. Under medical guidance, medications such as Lianhua Qingwen Capsules, Oseltamivir Phosphate Capsules, and Ribavirin Tablets may be used to inhibit viral replication.

  2. Pharyngitis

  When pharyngitis is caused by bacterial infection, bacteria multiply in the body and invade the throat area. Bacterial metabolic products release pyrogens that act on the body’s temperature regulation center, leading to fever. Symptoms may include throat pain, swelling, and dryness. Under a doctor's supervision, antibiotics such as Amoxicillin Capsules, Ampicillin Capsules, and Roxithromycin Dispersible Tablets can be used to treat the infection.

  3. Tonsillitis

  Pathogenic microorganisms entering the body can cause tonsillitis. The resulting inflammation stimulates the body, potentially disrupting the temperature regulation system and causing fever. This may be accompanied by chills, loss of appetite, and other discomforts. As advised by a physician, medications such as Cefuroxime Axetil Tablets, Cefradine Capsules, and Cefixime Dispersible Tablets may be used to help resolve the inflammation.

  4. Tuberculosis

  Infection with Mycobacterium tuberculosis leads to pulmonary tuberculosis, during which pathogens multiply extensively in the body and produce tuberculous toxins that stimulate the production of endogenous pyrogens. This condition may also present with symptoms such as cough and sputum production. Antituberculosis drugs such as Isoniazid Tablets, Rifampicin Tablets, and Pyrazinamide Tablets should be taken under medical supervision to effectively combat the infection.

  5. Hyperthyroidism

  In patients with hyperthyroidism, elevated levels of thyroid hormones accelerate metabolism, leading to an increase in basal body temperature. Symptoms may include palpitations and tachycardia. Medications such as Propylthiouracil Tablets, Methimazole Tablets, and Carbimazole Tablets can be prescribed under medical guidance to suppress thyroid hormone secretion.

  It is recommended to seek timely medical evaluation at a hospital, complete necessary diagnostic tests, determine the exact cause, and receive targeted treatment under professional medical supervision. During treatment, maintain a light diet and drink plenty of water to assist the body in dissipating heat.
