What to Do If Flu Symptoms Persist with Continuous Fever

Understanding Persistent Fever During Influenza

When flu symptoms linger and a fever refuses to subside, it's crucial to take timely and effective action. A persistent high temperature is often the body's response to fighting off the influenza virus. While mild cases may resolve on their own, prolonged fever could signal a need for medical intervention to prevent complications such as pneumonia or dehydration.

Effective Antiviral Treatment Options

Oseltamivir phosphate capsules are widely recommended for treating influenza, especially when administered within the first 48 hours of symptom onset. For adults, the standard dosage is 75mg taken twice daily for five days. Pediatric patients typically receive a reduced dose—often 25mg twice daily, adjusted based on age and weight. This antiviral medication helps inhibit the spread of the virus in the body, reducing both symptom severity and duration.

Complementary Herbal Remedies

In addition to prescription antivirals, certain traditional herbal medicines may support recovery. Over-the-counter options such as Lianhua Qingwen granules, Pudilan anti-inflammatory oral liquid, Isatis root (Banlangen) granules, Qingkailing granules, antelope horn powder, and Shuanghuanglian oral liquid are known for their heat-clearing and detoxifying properties. These remedies can help alleviate sore throat, reduce inflammation, and support immune function during flu season.

Natural Therapies and Traditional Chinese Medicine

For those seeking holistic approaches, customized herbal decoctions can be effective. In cases classified as wind-heat type influenza, formulas like Yinqiao San (Honeysuckle and Forsythia Powder) and Sangju Yin (Mulberry Leaf and Chrysanthemum Decoction), often modified based on individual symptoms, are commonly prescribed. These herbal blends work by promoting sweating, clearing internal heat, and expelling pathogens from the respiratory tract.

Lifestyle Adjustments to Support Recovery

Proper self-care plays a vital role in overcoming the flu. Staying well-hydrated by drinking plenty of fluids—especially water, herbal teas, and broths—helps thin mucus and prevents dehydration caused by fever. Adequate rest allows the immune system to focus its energy on fighting the infection. Supplementing with Vitamin C from citrus fruits, bell peppers, or quality supplements may also enhance immune defense and shorten illness duration.

Improving Indoor Air Quality

Maintaining good ventilation is essential. Opening windows regularly to allow fresh air circulation can significantly reduce the concentration of airborne viruses and lower the risk of transmission among household members. Additionally, some studies suggest that using vinegar fumigation in enclosed spaces may help purify the air. Simply heating a small amount of white vinegar in a pan releases vapors believed to have mild antimicrobial effects, offering a natural way to disinfect indoor environments during flu outbreaks.

When to Seek Medical Attention

If fever persists beyond five days, worsens after initial improvement, or is accompanied by difficulty breathing, chest pain, or confusion, prompt medical evaluation is necessary. These could be signs of secondary bacterial infections or other serious conditions requiring antibiotics or hospitalization. Always consult a healthcare provider before combining medications, especially when integrating Western and traditional treatments.
