NAZOFERON is an antiviral, anti-inflammatory, immunomodulatory, antiproliferative agent. The mechanism of antiviral action is to inhibit the replication of viruses (adenoviruses, influenza viruses, etc.) due to the inhibitory effect on the processes of transcription and translation; antiproliferative – inhibits cell reproduction (most DNA and RNA viruses). Interferon initiates the synthesis of a specific enzyme – protein kinase, which prevents translation due to the phosphorylation of one of the initiating factors of this process; activates a specific ribonuclease, which damages the messenger RNA of the virus. The effects of interferon also include: stimulation of the production of other cytokines, induction of specific enzymes, inhibition of cell proliferation, immunomodulation (increased phagocytic activity of macrophages and specific cytotoxicity of lymphocytes in relation to target cells). Interferon is an immune mediator and has a pronounced tissue specificity. Due to its effects, interferon protects the body from pathogens of infectious diseases (viruses, bacteria, mycoplasmas, pathogenic fungi, etc.).

Adults – 3 spray doses 5-6 times a day (single dose – 30,000 IU, daily dose – 150,000-180,000 IU).
For the prevention of respiratory viral infections
In contact with the patient and in case of hypothermia – in accordance with the age dosage 2 times a day for 5-7 days. If necessary, preventive courses are repeated. With a single contact, one injection is sufficient.
With a seasonal increase in the incidence – in accordance with the age dosage once in the morning with an interval of 1-2 days.
In isolated cases:
rash on the skin
dryness of the mucous membranes of the nasal passages
hypersensitivity to interferon alfa-2b and other components that make up the drug
severe forms of allergic diseases in history.
When using the drug NAZOFERON in uncomplicated cases, no additional symptomatic treatment is required (paracetamol, sulfonamides, vasoconstrictor nasal drops). At elevated body temperature, the drug is combined with anti-inflammatory drugs. The simultaneous use of intranasal vasoconstrictor drugs is not recommended, since they contribute to the drying of the nasal mucosa.
