How Popular Antiviral Medications Work for Colds and Flu

The influenza virus is an infectious respiratory illness that causes seasonal outbreaks each year and unpredictable pandemics with high rates of illness and mortality. Fighting colds and flu is not only a vital necessity but also a real challenge for the global community. The 2019 pandemic is a reminder, with more than 777 million confirmed cases worldwide and over 7 million deaths.

Due to busy schedules, many people ignore the first symptoms of flu or cold. This is why it is extremely important to take anti-cold medicines in time. Antiviral medications can shorten the duration of the illness, relieve symptoms, and reduce the risk of complications. The most popular options for flu and colds include Arbidol, Viferon, and Ingavirin.

Arbidol at the First Signs of a Viral Infection

Arbidol is a versatile antiviral medication effective against influenza viruses A and B. Its mechanism of action prevents viruses from penetrating human cells.

In addition, it also shows activity against viruses such as hepatitis B and C, chikungunya virus, reovirus, and Hantaan virus.

Clinical studies have demonstrated the effectiveness of Arbidol in reducing the severity and duration of flu symptoms.

Along with antiviral properties, Arbidol also has an immune-modulating effect. It can enhance the body’s immune response against viral infections by activating specific immune cells. It is generally well tolerated, with common side effects being mild and temporary.

Viferon for Treating and Preventing Colds in Children

Viferon is widely used for treating and preventing colds. Interferon is its main component — a protein produced naturally by the body in response to viral invasion or made synthetically in laboratories. Interferon triggers chemical reactions that block the reproduction of viral DNA and RNA.

For more than 25 years, the company has accumulated extensive experience using Viferon to treat a wide range of conditions (including ARVI and flu, herpesvirus and urogenital infections, and viral hepatitis B, C, and D), confirmed by numerous clinical studies.

Ingavirin as a Modern Flu Remedy

Ingavirin contains imidazolylethanamide of pentanedioic acid as its active ingredient. This component is effective against influenza, parainfluenza, and respiratory syncytial viruses. It works by blocking viral replication at an early stage, preventing the movement of viral particles from the cytoplasm into the cell nucleus. This disrupts the viral life cycle and stops further spread, helping to reduce viral load in the body.

For treating and preventing flu and acute respiratory viral infections in adults, the recommended dosage is 90 mg once daily. Treatment duration is 5–7 days depending on the severity of the condition. The best results come from starting the medication as soon as symptoms appear, ideally within two days of onset.

Ingavirin is considered a modern antiviral solution due to its combined direct antiviral and immune-modulating action, convenient dosing schedule, form of release, and broad spectrum of activity.

OTC medication for colds such as Ingavirin, Viferon, and Arbidol is effective in combating viral and cold-related illnesses thanks to their unique properties and wide range of action.
