About 90% of global population is infected with herpes virus. Medical disorder in 80% of infected patients is asymptomatic. A person may not know about it and infects other people. Scientists identify 8 types of herpes virus. Despite the fact that most people are sure that the herpes virus is quite harmless, this is in fact completely wrong. Different variations of the herpes virus can affect almost the entire body and cause a number of very serious diseases.
Neglecting the treatment of herpes can lead to damage to the brain, heart, eyes. Herpes can be transmitted to the fetus in utero.
Effects of herpesvirus types 6, 7 and 8 were not fully studied.
Anything that weakens the immune system can lead to a relapse of the disease (for example, physical and mental stress, fatigue, colds).
Viruses can hit:
- oral cavity (stomatitis, gingivitis);
- visual tract (keratitis, iridocyclitis, chorioretinitis, optic neuritis, phlebothrombosis);
- skin and mucous coats (herpes of the face, lips, genital herpes, etc.);
- gastrointestinal tract (hepatitis, ileocolitis, proctitis);
- lungs (bronchopneumonia);
- ENT-organs (pharyngitis, herpetic angina, laryngitis, otitis, sudden deafness, vestibular disorders);
- cardiovascular system (myocarditis, myocardiopathy, HSV is involved in the processes underlying atherosclerosis);
- psycho-emotional sphere (depression, an aggravating effect of HSV on the course of senile dementia and schizophrenia);
- female genital organs (genital herpes-colpitis, intrauterine device HSV infection: endometritis, amnionitis, chorionitis, metroendometritis, impaired fertility function);
- male genital organs (genital herpes-prostatitis, urethritis, sperm infection);
- lymphatic apparatus (HSV-lymphadenopathy);
- cerebrospinal axis (encephalitis, sympathogangleoneuritis, nerve plexus lesion).
Antiviral drugs are effective in different cases of herpes. They quickly block the multiplication of the virus and make it to “fall asleep” for a while. Zovirax is one of these medicines. It quickly removes symptoms, facilitates the healing of ulcers, skin regeneration or mucous coats.
Components and features
The active ingredient of the preparation is Acyclovir. Active substance integrates into the DNA of herpes and stops reproduction of the virus. The active ingredient is partially absorbed after oral exposure. The rest of the substance is discharged unchanged through the kidneys. The active substance has a high selectivity of action and low toxicity for humans.
People suffering from immunity disorders should not use this medicine for a long time. It is addictive and becomes useless in the future. In this case the doctor must decide how long a patient can apply the medicine.
History of the medicine
The active substance of the medicine (Acyclovir) was first synthesized in 1974 by Howard Scheffer, an employee of Wellcome Research Laboratories. This was one of the biggest global pharmaceutical companies, which held a lot of various researches and created several medicines, which are currently recognized in many countries of the world as on optimal solution to treat various disorders.
Among its products one will find some treatments for oncology, cardiac and vascular systems etc.
However, the glory of the inventor of the world's first antiviral drug stuck not to Howard Scheffer, but to another laboratory employee, Gertrude Bell Elion. Together with James Blake and other colleagues from the laboratory of Gertrude, Elion conducted a lot of clinical blind trials, covering 2 group of patients – reference and placebo every time. Several years of hard work produced an effective and needed result – the product, which has recently become a bestseller in its product category.

James: Zovirax copes with my problem pretty good. The cream is thick and I apply it comfortably. I used it in a wrong way before. I started to smear herpes after he already showed up. Start as soon as you feel itching until the bubbles appear.
As soon as there are bubbles of herpes on the skin do not tamper with it and do not scratch it. It will only get worse. I smear such places on the body and I do it strictly several times a day. In 2 days the inflammation subsides and a crust is formed which can not be torn off. In a couple of days the crust will fall off itself and there will be a red speck that will quickly disappear. Do not apply ointment too often otherwise there will be a burn. By the way, if herpes showered a lot of places on your face or body try medicine in tablets. It treats the virus from the inside.
Ashley: I have such organism that the herpes appears very often and it was necessary to live a week or more with “beautiful” lips. Once the itching on the lip started (itched for two days) but the herpes has not appeared at that time yet. I decided to try Zovirax. It is produced in a small tube in which there is only 2 g of ointment, but it is enough actually. It helped me. The itch disappeared after 2 applications. I was very happy. I apply one or two times as soon as the itching appears and everything passes.
Candy: I'm ill with herpes since the childhood. I'm constantly on the lookout for a fast-acting remedy for this disease. I applied Gerpevir earlier. I was advised to buy Zovirax this time. I used this medication for a day. My lip was swollen in the morning. A lot of bubbles appeared on it. The itch was very strong. I do not recommend Zovirax to those who have long used the means in which the concentration of the active substance is greater than in this medicine. Most likely, your body, like mine, has become accustomed to a greater concentration and there will be no effect from Zovirax.
Jonathan: Herpes for me was a big disaster until I started using Zovirax. I have been using this medicine for more than three years. It works quickly and efficiently. I give a high score to this medicine.
Jim: I just do not know the better medicine. I tried many preparations including folk medicine. But everything is weak. Herpes, unfortunately, is a companion in my life. I do not know how to live without this medicine. The drug is always with me. By the way, it removes pre-herpes itching and the flaking of the lips very well.
