Do immunomodulators work?
The effectiveness of most drugs advertised in Russia as antiviral agents, immunomodulators or "cold remedies" has not been confirmed by clinical tests, and in most countries of the world these medications are simply not sold.
For example, the widely popular Arbidol is produced only in Russia and CIS countries, whereas the American supervisory organization Food and Drug Administration refused to register the drug as a medicinal product in the USA( 1).
Is Arbidol harmful?
In the international medical base Medline since 1964 there are only four publications devoted to studies of the drug "Arbidol".Two of them, dated 2008, describe very controversial tests with contentious results.
In the seventies in the USSR, this drug was mass tested on thousands of subjects, but the results were never published. What could be in them - remains a mystery, but no one even excludes the potential harm of the drug.
Is Oscilococcinum effective?
On the assurances of the producers, the homeopathic preparation Otsilokoktsinum contains particles of the liver of the magic duck - but it is diluted 10,400 times, which means that there is not even one molecule of active substance in the package of this "medicine"( 1).
There is only one scientific study of this drug, according to which testing on 3500 patients did not show effectiveness, because only for some people the duration of the disease was reduced by no more than 6 hours.
Means for the prevention of colds
Oxolin ointment, recommended by the manufacturer as a prophylactic, also has no proven effectiveness. Not to mention that the very idea of her work - applying ointment on the nasal mucosa that can stop the virus - is unscientific.
Rimantadine has shown effectiveness only to fight the influenza A virus, but the cold has no effect on the common cold. Accordingly, all drugs based on it can not be treated or saved from a cold.
Fervex and Coldrex
Preparations based on paracetamol, Fervex, Koldrex, Teraflu and many others, in advertising speak not about treatment, but only about the removal of symptoms of the disease. This is not surprising, since there is nothing in their composition that can cure.
Such an ordinary drug as paracetamol, in no way affects the viral diseases, and is not able to stop the cold, as many think. In addition, taking the drug at night is dangerous for the stomach mucosa.
Large doses of vitamin C
In the history of the Nobel Prize, there is only one person who received it twice - Dr. Linus Karl Pauling. One of Dr. Pauling's main beliefs was that large doses of vitamin C can cure a cold and increase immunity( 2).
Pauling believed that taking 3-10 gr.vitamin C in the early days of the disease accelerates recovery. Despite the fact that the theory has not been confirmed, such doses of vitamin C are permissible, and you, at least, can test it for yourself.
Taking vitamins and zinc
Vitamins in themselves are not able to cure a cold, but their deficiency worsens the immunity and increases the risk of the disease. For example, vitamin A is essential for the functioning of the immune system and is an integral part of the fight against infection.
In addition, the immune function of the body increases the intake of zinc. Some experts believe that taking zinc in the first days of illness helps to fight the virus. If the daily dosage is 25 mg, then in the first days of a cold, 60 mg are permissible.
Most of the antiviral drugs sold in Russian pharmacies have no evidence base, and are dummy. At the moment there are no drugs that can effectively stop the development of colds.
