Does Arbidol hydrochloride treat influenza A?

Generally, arbidoL hydrochloride can be used to treat influenza A, but it must be taken strictly according to medical advice. If abnormal symptoms or discomfort occur during medication, prompt medical attention is recommended. The detailed analysis is as follows:

Arbidol hydrochloride is an antiviral drug that works by inhibiting the fusion of the viral lipid envelope with host cells, thereby blocking viral replication and transmission. It is specifically effective against influenza A virus, particularly showing significant inhibitory effects on the influenza A H1N1 strain. Clinical studies have shown that when administered within 48 hours of symptom onset, it can shorten the duration of symptoms such as fever, cough, and sore throat, alleviate systemic toxic symptoms like muscle aches and headache, and reduce the likelihood of complications including viral pneumonia and myocarditis.

The drug may cause adverse reactions such as nausea, diarrhea, and dizziness. Pregnant women, breastfeeding women, and patients with severe hepatic or renal impairment should use it cautiously. Concomitant use with other antiviral drugs should be avoided during treatment to prevent potential drug interactions.

During treatment with arbidol hydrochloride, adequate rest is essential. Patients should drink 1,500–2,000 mL of water daily and consume easily digestible foods such as porridge and steamed eggs. If symptoms do not improve after three days of treatment, or if unusual reactions such as rash or difficulty breathing occur, the drug should be discontinued immediately and medical help sought.
