Inosine formula The active ingredient is Inosine pranobex, which exhibits antiviral effects and is also an immunomodulator.

Inosine pranobex enhances the production of natural factors of cellular immunity, and also increases the amount of immunoglobulin.

In addition to enhancing immunity, the fight against the virus occurs due to the inhibition of virus reproduction.

An additional component is mannitol, which can have a laxative effect that does not require discontinuation of treatment.

I was prescribed Isoprinosine for ARVI. The doctor said that this is one of the best drugs. I drank it for 5 days and I am pleased with the result. Already on the third day, the symptoms were gone, and I began to feel much better. Immunity from taking Izoprinozin was enough for another couple of months. Elena, Moscow

Isoprinosine was prescribed to my mother for papillomavirus infection. In combination with cryotherapy, we achieved the desired effect - all papillomas disappeared, and new ones did not appear. But the course will need to be repeated in order not to get a relapse of the disease. The only negative is the high cost of the drug, it is especially expensive for a monthly course of treatment. Vika, Krasnodar

I drank Izoprinozin for herpes, combining tablets with an external antiviral ointment. Yes, the herpes has passed, but I cannot say that it is only thanks to Isoprinosine. The effect of it was the same as that of other antiviral drugs, but the cost of treatment was more expensive. But I like the effect of Izoprinozin with ARVI in children. The dose is calculated individually, according to the weight of the child, therefore, cases of overdose or, conversely, treatment failure are excluded. Igor, Saratov

  • Stanislav :

    My friend has herpes number 4 and Epstein Bara, suffered for many years. After taking isoprinosine, on the third day I felt an improvement. But this medicine is nowhere to be found. He has one course, the second and third not. What to do and where to buy?

    • Julia :

      We have the same problem with the child. It was possible to learn from a reliable source that his analogue Groprinosin should appear in Russia after March 2017. But we urgently need to, so we are trying to order in Ukraine, where this drug is commercially available.
