Introduction
Oseltamivir phosphate capsules are an antiviral medication primarily targeting influenza A and B viruses. It inhibits the neuraminidase on the viral surface, preventing the spread of the virus within the body and suppressing further viral replication. This medication can effectively alleviate symptoms of influenza, such as high fever, cough, sore throat, muscle pain, and fatigue.

Oseltamivir capsules usually refer to oseltamivir phosphate capsules. The effects of this medication generally include antiviral, alleviating symptoms of influenza, shortening the duration of illness, preventing infection, and reducing the risk of complications.

1. Antiviral

Oseltamivir phosphate capsules are an antiviral medication primarily targeting influenza A and B viruses. It inhibits the neuraminidase on the virus surface, preventing the spread of the virus within the body and suppressing further viral replication.

2. Alleviating Symptoms of Influenza

This medication can effectively alleviate symptoms in patients with influenza, such as high fever, cough, sore throat, muscle pain, and fatigue. By inhibiting viral replication and reducing the damage viruses cause to body tissues, these symptoms can be relieved.

3. Shortening the Duration of Illness

This medication helps shorten the course of influenza. Oseltamivir phosphate capsules accelerate the body's clearance of the virus, reducing the illness duration to about 3-5 days. Patients can recover to their normal daily activities and work more quickly.

4. Preventing Infection

High-risk individuals who have been in contact with influenza patients may use oseltamivir phosphate capsules for infection prevention. The medication inhibits the replication of influenza viruses entering the body, thereby reducing the likelihood of infection.

5. Reducing the Risk of Complications

This drug can reduce the risk of complications caused by influenza. If influenza is not promptly controlled, it may lead to severe complications such as pneumonia, myocarditis, and otitis media. Oseltamivir phosphate capsules reduce the occurrence of complications by inhibiting viral activity and decreasing inflammatory responses.

Patients should use this medication under the guidance of a physician and should not take it arbitrarily. During recovery, adequate rest and sufficient fluid intake are recommended to support the healing process.

Does Lianhua Qingwen treat allergic asthma?
The core effects of Lianhua Qingwen are clearing away epidemic toxins, detoxification, promoting lung function, and relieving heat. It is primarily used to treat influenza due to heat-toxin attacking the lungs, and is not intended for the treatment of allergic asthma. Allergic asthma results from an abnormal immune response to allergens and requires targeted anti-inflammatory and anti-allergy treatments. Patients with allergic asthma should seek timely evaluation and standardized treatment at a respiratory medicine department.

Can pulmonary fibrosis be improved by running?
In general, pulmonary fibrosis cannot be reversed through running. However, when the condition is stable, moderate running may help improve cardiopulmonary function. During acute exacerbations, running can increase physical strain and should be avoided. Patients with pulmonary fibrosis must strictly follow medical advice for treatment and adjust their activity levels according to disease status. A diet rich in high-quality protein and vitamins is recommended, and exposure to irritants such as dust and smoke should be avoided.

Can Lianhua Qingwen Granules treat yellow nasal discharge?
Lianhua Qingwen Granules are effective in relieving yellow nasal discharge caused by heat-toxin attacking the lungs, but less effective for cases due to cold-wind invasion or bacterial infection. If yellow nasal discharge is accompanied by symptoms such as fever, sore throat, cough, and yellow, thick phlegm—indicative of heat-toxin affecting the lungs—Lianhua Qingwen Granules can be beneficial. Containing ingredients like Forsythia suspensa (Lianqiao) and Lonicera japonica (Jinyinhua), this formula helps clear epidemic toxins, resolve heat, and promote lung function, thereby improving the aforementioned associated symptoms.

Can solifenacin be taken long-term?
For patients with chronic conditions requiring long-term management, such as overactive bladder, solifenacin may be taken long-term as prescribed if symptoms show significant improvement after treatment and regular examinations reveal no serious adverse reactions. When a physician's comprehensive assessment determines that the benefits outweigh the risks, continued use is appropriate. This medication helps stabilize bladder function and, with long-term use, can continuously alleviate symptoms such as frequent urination and urgency, thereby improving quality of life.

What traditional Chinese medicine should be taken for allergic asthma?
For allergic asthma, traditional Chinese herbs such as Ephedra (Mahuang), Perilla seed (Zisuzi), Bitter Apricot Seed (Kuxingren), Earthworm (Dilong), and Astragalus (Huangqi) may be used under medical guidance. Treatment should be individualized based on syndrome differentiation—including cold asthma, heat asthma, or deficiency of lung and spleen qi—with emphasis on relieving wheezing, stopping cough, resolving phlegm, promoting lung function, and strengthening qi to consolidate the body's defenses. If acute asthma attack occurs with difficulty breathing or persistent wheezing, prompt medical attention is recommended.

Is quitting smoking helpful for frequent shortness of breath?
Frequent shortness of breath can be effectively alleviated and respiratory function significantly improved by quitting smoking. Harmful substances in tobacco smoke damage the respiratory mucosa and exacerbate airway spasms and inflammation. Quitting smoking reduces irritation and slows the decline of lung function, making it a key measure to relieve wheezing. If shortness of breath is accompanied by chest pain, blood-tinged sputum, or worsening breathing difficulties, prompt medical attention is recommended.

Can a cold cause nausea or vomiting?
If a cold is of the gastrointestinal type or if a viral infection triggers systemic reactions, symptoms such as nausea or the urge to vomit may occur. Gastrointestinal-type colds are often accompanied by digestive symptoms like bloating and diarrhea; the virus irritates the gastrointestinal mucosa, leading to gastrointestinal dysfunction. Additionally, in some individuals, the physical discomfort caused by a cold may trigger a stress response that stimulates the vomiting center, resulting in feelings of nausea and an urge to vomit.
