Interferon therapy for COVID-19 in children: theory and practice


From this article you will learn:
  • release forms of the drug Viferon,
  • instructions for use, reviews,
  • clinical efficacy studies.

Viferon is a drug based on recombinant human interferon alpha-2b (Russian production), intended for the treatment of bacterial and viral infections. The drug is often prescribed for herpetic lesions of the oral mucosa in children. In addition to interferon alpha-2b, the drug contains vitamins E and C. The drug is considered safe and can be used even in newborns.

According to the manufacturer, Viferon has a large list of functional activities - primarily an antiviral effect, as well as immunomodulatory, antiproliferative and other properties. The drug has release forms - Viferon suppositories with dosages of 150,000 IU, 500,000 IU, 1,000,000 IU, 3,000,000 IU, as well as Viferon gel and ointment. The choice of release form will depend on the age of the child or adult, as well as on the location of the infectious focus (inflammation). The drug is intended for over-the-counter use.

For infants, the most convenient form is in the form of suppositories (candles). Accordingly, when using this form, the localization of the source of inflammation will be completely unimportant, because the drug will spread through the bloodstream. But for adults and children of middle and older age, of course, it is better to choose forms for topical use in the form of an ointment or gel. For various diseases, the choice of ointment and gel form is important.

For example, only Viferon-gel is suitable for application to the mucous membrane, because the gel form will adhere well to the moist mucosa. There is no point in applying Viferon ointment to mucous membranes. Remember that absolutely any preparations in the form of ointments or creams (i.e., fat-based) make sense to use only when the source of inflammation is localized on the skin of the face or the red border of the lips. In case of damage to the mucous membranes, preparations for topical use should only be in the form of gels.

Ointment "Viferon": composition, description

This is an antiviral drug that strengthens the immune system. The composition contains interferon protein, which belongs to the alpha-2b type. Available in different forms:

  • ointment;
  • candles;
  • gel.

It is used for the prevention and treatment of diseases associated with viruses. Thanks to the destruction of pathogenic microorganisms, patients can use significantly less hormonal drugs and antibiotics, which makes them feel better and has a positive effect on their health.

The effect on the body is complex:

  • antiviral – for the treatment of herpes, influenza, hepatitis, among others;
  • restoration of the interferon synthesis system;
  • antibacterial – treatment of mixed infections;
  • stimulation of systems that synthesize antibodies;
  • strengthening the immune system.

The drug stabilizes the membranes of body cells, promotes tissue regeneration, and has anti-inflammatory and powerful antioxidant effects. This contributes not only to cure from infectious pathologies, but to relatively rapid recovery.

The ointment or gel can only be stored in the refrigerator at a temperature in the range of 2-8°C. The place should be moderately damp and dark. Access for children is prohibited. The drug can be used within the expiration date, which is 2 years from the date of production.

Pharmacodynamics

Human recombinant interferon alpha-2b has pronounced immunomodulatory, antiviral, antiproliferative properties, suppresses the replication of RNA and DNA viruses.

The complex composition of the drugs (ointment, suppositories, gel) causes a number of new additional effects: in the presence of antioxidants (tocopherol acetate and/or ascorbic acid), the specific antiviral activity of human recombinant alpha-2b interferon increases, its immunomodulatory effect on T- and B-lymphocytes increases , the level of secretory immunoglobulins of class A increases, the level of immunoglobulin E normalizes, and the functioning of the endogenous interferon alpha-2b system is restored. Ascorbic acid and alpha-tocopherol acetate, being highly active antioxidants, have anti-inflammatory, membrane stabilizing, and regenerating properties. The use of the drug VIFERON® as part of complex therapy makes it possible to reduce therapeutic doses of antibacterial and hormonal drugs, as well as reduce the toxic effects of this therapy.

It has been established that when using the drug VIFERON® there are no side effects that occur with parenteral administration of interferon alfa-2b preparations, and no antibodies are formed that neutralize the antiviral activity of interferon alfa-2b.

Candle rating

To improve the child’s well-being due to teeth growth, suppositories help.

Let's look at the drugs that can be used:

Viburkol

The product is considered homeopathic because it is produced on the basis of a plant component. The suppository effectively helps with teething. It relieves the pain threshold, body temperature drops, and gum inflammation is significantly reduced.

After using the product, the child feels much better. His irritability goes away and he becomes less capricious.

1 package of the drug contains 6 suppositories. If you follow all medical prescriptions, side effects are reduced to zero. There is a possibility that an allergic reaction will occur, but this is only if the child is intolerant to a component of the drug. After the first use, it is necessary to monitor the baby’s condition.

If you have an unhealthy reaction, you should inform your doctor. He will prescribe another medicine.

The drug should be taken as prescribed by a doctor or according to the instructions for use.

The average price in pharmacies for Viburkol suppositories is 360 rubles.

Panadol

The product is available in spirit forms: syrup and candles. It is most convenient for infants to use suppositories. The product is based on paracetamol. It helps lower body temperature and relieve pain. Suppositories can be used until the child reaches 6 months of age.

The drug has several limitations when used:

  1. Intolerance of the body to one of the components of the drug.
  2. It cannot be used for pathologies with the kidneys or liver.
  3. For inflammation of the rectum.
  4. For blood disease.

Nurofen

Nurofen suppositories contain ibuprofen, which has a healing effect. It is recommended to use the product for fever and pain. The dosage is calculated based on the body weight and age of the child.

It is allowed to use the drug only after the baby reaches the age of 3 months. The product must be used with caution. It is worth using suppositories in a minimal course or a one-time method and in the smallest dosage.

With prolonged use, side effects may occur. Before using the drug, you must read the instructions. The drug has a large list of restrictions on use.

Viferon

Antiviral drug. The composition includes interferon alpha and vitamins E, C. The drug is prescribed for colds and for teeth growth. The drug does not help reduce fever and does not relieve pain. They only increase the baby’s immunity.

During teething, the temperature rises and the general condition of the body weakens. This may cause a viral disease. To prevent this from happening, Viveron suppositories are prescribed. They promote immunity to fight diseases.

The average price in pharmacies for Viveron suppositories is 170 rubles.

Indications and contraindications

When the first teeth erupt, the baby may begin to be capricious. The child experiences sleep disturbances, refuses to eat, body temperature rises, and the baby experiences pain. Such symptoms can be observed in many diseases, this is the reason to make sure that the symptoms appear due to the growth of teeth.

As soon as the baby pulls everything into the oral cavity, parents need to examine the mouth and gums. If the gum is inflamed and there is a whitish lump on it, then this indicates only one thing. The child’s pain will go away after the tooth passes through the bone tissue and gums.

It can take some time. To eliminate discomfort, you can resort to medication.

If the baby is correctly identified as feeling unwell, suppositories have no contraindications. Of course, if the baby is not allergic to the components included in the product.

In pharmacology, there are 2 types of drugs that can help with tooth growth:

  • local painkiller, these are gels or ointments;
  • anesthetics that are taken orally.

A suppository is considered one of the safe and effective medications. It is recommended to resort to his help as a last resort, when the child can no longer endure the pain, and the pediatrician prescribes their appointment. You should not self-medicate; it is better to consult your pediatrician.

For pain, children are prescribed medications that can have a mild effect. The age of the child also becomes a criterion when choosing medications. For infants, suppositories are prescribed, for older children - suspensions.

Use during pregnancy and breastfeeding

Ointment: since when applied externally and locally, the systemic absorption of interferon is low and the drug has an effect only in the lesion, it is possible to use the drug VIFERON® during pregnancy and lactation.

The drug Viferon: reviews and studies

Let us say right away that the treatment of viral and bacterial diseases with interferons is recognized in the USA and Europe, and even in Kazakhstan, which is close to us, as ineffective. Clinical studies that were published in Russia have a level of evidence – class II (B). This means that small randomized controlled clinical trials were conducted, involving only a small number of people. From the point of view of evidence-based medicine, such studies do not inspire much confidence. Nevertheless, sales of Viferon are a very large market of several billion rubles.

As a doctor (my personal opinion), I do not consider the drug Viferon to be effective, and I have never seen a significant positive result from its mono use. As for patients, patient reviews of Viferon are absolutely diverse, because... Patients usually take several medications at once. Therefore, it is easy to make a mistake in interpreting the results, because the result could have been achieved through another drug, or simply through the natural cessation of the disease. This is well demonstrated by the proverb: To treat a cold or not to treat it, it will still go away in 7 days.

Side effects

Ointment: in most cases, VIFERON® is well tolerated. When applied to the nasal mucosa, side effects are weak and transient and disappear on their own after discontinuation of the drug.

Gel: in extremely rare cases, a local allergic reaction may occur in some highly sensitive individuals. In such cases, stop using the drug.

Suppositories: in rare cases - allergic reactions (skin rashes, itching). These phenomena are reversible and disappear 72 hours after stopping the drug.

Recommendations for use

Suppositories must be used exactly as prescribed by the pediatrician; the dosage must be observed and the drug must be used correctly.

How to use candles:

  1. The person administering the product must wash their hands. To do this, it is better to use an antibacterial agent or laundry soap. This is necessary so that the infection does not enter the child’s colon.
  2. If the child is under 1 year old, then he is placed on his back and his legs are held in his hands. When the baby is more than a year old, he is placed on his side and his legs are bent towards his stomach.
  3. Before administering the product , you must remove the packaging and warm it in your hands. Lubricate the child's anus with cream.
  4. Spread your butt and insert the product into the anus. Close the child’s buttocks and wait a while. This is necessary so that the drug does not come out.
  5. The baby should lie down for a while so that the product is better absorbed and absorbed.

Directions for use and doses
