Introduction

H1N1 influenza refers to type A H1N1 flu, and high fever refers to elevated body temperature. For persistent high fever of 39°C caused by H1N1 influenza, symptoms can be alleviated through maintaining adequate fluid intake, proper rest and adjustment, dietary regulation, physical cooling methods, and medication. If any discomfort occurs, it is recommended to seek immediate medical attention to avoid delaying treatment and prevent adverse outcomes.

　　H1N1 refers to influenza A (H1N1), and high fever refers to hyperthermia. For persistent high fever of 39°C caused by influenza A (H1N1), symptoms can be alleviated through maintaining adequate hydration, rest, dietary adjustments, physical cooling, and medication. If any discomfort occurs, immediate medical attention is recommended. Details are as follows:

　　1. Maintain adequate fluid intake

　　During high fever, the body loses fluids rapidly; therefore, sufficient fluid intake is essential to maintain water and electrolyte balance. Drinking warm water, hot beverages, or fruit juice can help reduce body temperature.

　　2. Rest and adjustment

　　Adequate rest is crucial during episodes of high fever. Try to stay in a comfortable and quiet environment, avoiding excessive physical activity and noisy surroundings.

　　3. Dietary adjustments

　　Plan meals appropriately, focusing on light and easily digestible foods such as rice porridge, noodles, and vegetables. Increase intake of vitamin C and other nutrients to strengthen the immune system.

　　4. Physical cooling

　　Apply physical cooling methods, such as wiping the patient's body with lukewarm water, especially the forehead, neck, armpits, and groin areas. Cooling patches or ice packs applied to the forehead and neck may also help lower body temperature.

　　5. Medication for symptom relief

　　Take antipyretic and analgesic medications as directed by a physician, such as ibuprofen tablets, acetaminophen tablets, or febuxostat tablets. Antiviral drugs such as oseltamivir phosphate granules, acyclovir tablets, or ribavirin tablets may also be used under a doctor’s guidance.

　　When using medications, always follow the doctor’s instructions strictly regarding dosage and administration to avoid delaying treatment or causing adverse effects.

Are the effects of Lianhua Qingwen Granules and Lianhua Qingwen Capsules the same?

The core ingredients of Lianhua Qingwen Granules and Capsules are identical, both primarily composed of Forsythia suspensa, Lonicera japonica, honey-fried Ephedra sinica, and other components. They are mainly used to clear away epidemic toxins, resolve toxicity, promote lung function, and relieve heat. Both formulations have similar therapeutic effects in regulating and alleviating symptoms such as fever, muscle aches, nasal congestion, and runny nose caused by influenza attributable to the pattern of heat-toxin attacking the lungs.
