Can sodium diclofenac sustained-release capsules reduce fever?
Generally speaking, diclofenac sodium sustained-release capsules can reduce fever. The detailed analysis is as follows:

Diclofenac sodium sustained-release capsules mainly contain ingredients such as diclofenac sodium, which can inhibit the synthesis of prostaglandins in the body, thereby reducing the sensitivity of pain receptors and achieving antipyretic, analgesic, and anti-inflammatory effects. It can be used to treat fever symptoms caused by infections, autoimmune diseases, and other conditions.
However, the primary function of diclofenac sodium sustained-release capsules is not specifically aimed at reducing fever. Long-term use may cause side effects such as headache, dizziness, and fatigue. Therefore, it is not recommended to use diclofenac sodium sustained-release capsules alone as a fever-reducing medication.
In daily life, it is advisable to take the medication in appropriate amounts under a doctor's guidance and closely monitor physical conditions to avoid adverse reactions. During the course of medication, spicy and stimulating foods, such as chili peppers and spicy snacks, should be avoided, as they may increase the burden on the gastrointestinal tract. Consuming fresh vegetables and fruits, such as Chinese cabbage, rape, apples, and bananas, is recommended to aid in recovery. Additionally, maintaining healthy lifestyle habits and engaging in moderate exercise can enhance immune function and promote physical recovery.
