Grippferon shelf life
The drug Grippferon ®, nasal spray dosed, has antiviral, immunomodulatory and anti-inflammatory effects.
The biological activity of the drug is due to the active substance - interferon alpha-2b human recombinant.
The antiviral effect of interferon alpha-2b is to create protective mechanisms in the virus-free cells that prevent the penetration of the virus into them and the assembly of virions. Interferon alpha-2b induces the synthesis of the key antiviral enzyme 2 ', 5'-oligoadenylate synthetase, which leads to inhibition of translation (biosynthesis) of the viral protein and induction of apoptosis (death) of organism-infected cells. Infected dead cells are removed using EK-cells activated by interferon.
The immunomodulatory effect of interferon alpha-2b consists in the activation of macrophages, cytotoxic T cells, NK cells (natural killer cells), increased phagocytosis and expression of antigens of the main histocompatibility complex, stimulating bone marrow cell proliferation and differentiation, which significantly increases the effectiveness of antiviral protection. When intranasal administration, interferon alpha-2b increases the expression of aquaporin-5 (AQP-5), interferon-stimulated gene-15 (ISG-15), histocompatibility antigens (HLA-DR) on mucosal epithelial cells and lymphoid cells.
The anti-inflammatory effect is mediated by reactions of the immune system, enhanced under the influence of interferon alfa-2b.
Intranasal administration of interferon does not cause forms of viruses that are resistant to its antiviral effect.

Effective and versatile
It is a liquid immunomodulator with antiviral and anti-inflammatory effects. It is produced in the form of nasal drops or spray. The active ingredient is interferon - a special protein that can fight viruses. Getting on the mucous membrane, it stops the reproduction in the body of the causative agents of influenza, parainfluenza, adenoviruses, etc. Influenza is also used for the prevention of influenza and ARVI during epidemics.
Suitable for all age groups, including infants and pregnant women.
Contraindications for use are individual intolerance to its components and severe allergic diseases.
Storage location - refrigerator
But the medicine is capricious. Aby where in the closet can not put it. I want to give you some tips on how to store influenza after it is opened.
So, you decided to use the help of grippferon and opened the package. After using the medicine in the bottle, of course, still remains. What's next? Is it possible to save the drug until the next time or is it too short after storage? How much can it be stored at all and what conditions need to be created so that it remains effective for as long as possible?
Grippferon is stored, according to the instructions, month since opening the bottle. In a month, the medicine discovered by alien bacteria is contaminated to such an extent that you can’t understand it anymore - it treats it more or hurts. In order not to forget to throw out the bottle, I recommend to sign the date of first use directly on it.
It is necessary to store the medicine, according to the same instructions for use, at 2-8 ° C. in the refrigerator, where the required temperature is maintained
By the way, sealed flupferon should also be stored in the refrigerator. The standard shelf life is 2 years.
If suddenly in a pharmacy you are offered a drug not from the fridge - refuse to buy! Storage conditions must be respected at all stages.
Not for long - you can
Doctors say that grippferon will not deteriorate, even if it will stay in the room for some time. So it is quite possible to take it with you to work or to school, and put in a cold place only for the night. But, of course, you should not abuse it, if there is a possibility - let it be better kept in the cold.
Many parents believe that cold drops can harm a child suffering from a cold. In fact, nothing wrong with that. After a couple of chilled drops, the child’s condition cannot deteriorate. But if you feel better about it, you can warm the bottle with the warmth of your hands.
Little bit about squirrel
Do not store the drug for a long time at a temperature above 8 ° C. I can explain why. Do you remember that the active ingredient of influenza is protein? And what will happen to protein if it is very hot? Of course, it will curl up and lose all its beneficial properties - this is what happens with the well-known whole egg chicken protein if it is cooked or fried.
Scientists call this process denaturation, and different proteins have different temperatures at which this process begins. For denaturation of the protein, which contains influenza, will be enough and +10 ° C.
So if you do not comply with the conditions of its storage, after a couple of days it will become completely useless, and with intensive use it may even cause an allergic reaction.
