Reducing fever is called antipyresis. The time required for fever reduction after taking antipyretic medication varies from person to person, but generally, fever should subside within 0.5 to 2 hours.
After taking antipyretic medication, the drug is gradually absorbed into the bloodstream and begins to act on the body's temperature-regulating center, causing the central set point to decrease. This leads to increased sweating through the sweat glands, allowing effective dissipation of body heat through perspiration, which may lower body temperature. Typically, the drug reaches peak effectiveness in about two hours. It is recommended to drink plenty of water after taking antipyretic medication to promote metabolism and replenish electrolytes. If, after two hours, the body temperature does not decrease upon re-measurement or continues to rise, it is advisable to seek medical attention for alternative antipyretic measures to avoid worsening of the condition.
When experiencing fever, attention should be given to dietary adjustments, adequate rest and warmth, hydration, avoiding excessive physical activity, and following medical instructions for medication. Personal and environmental hygiene should also be maintained, and contact with potential infection sources should be avoided to prevent worsening of the illness or spreading it to others. If fever symptoms worsen or persist for an extended period, prompt medical consultation and treatment are advised.
