Taking Zovirax 400mg can reduce the symptoms of red, swollen lesions and shorten the healing time. In general, herpes tends to be more severe at the time of primary infection than at recurrence, but even with initial infection, Zovirax 400mg can cure herpes relatively quickly. But there is one thing you should be aware of. That is, Zovirax 400mg, which seems to be a panacea against herpes, cannot completely eliminate the herpes virus from the body.

Zovirax 400mg does not kill the herpes virus. However, it has the effect of inhibiting proliferation and stops the worsening of symptoms. The virus that is active in the body is gradually inactivated by the body’s own immunity and stops its activity. This can lead to early treatment.

About Zovirax 400mg

Zovirax 400mg is a drug containing acyclovir as the active ingredient. The symptom improvement rate is reported to be about 95%, and a very high effect can be expected. It is said that this acyclovir suppresses the activity of the pathogenic virus and can be cured in about a week at the shortest.

In addition, there are many dosage forms (tablets, creams, etc.), so you can buy the dosage form that suits you over the mail order, and it is used by many people.

Early treatment of at least 1 week with active ingredients is possible

Herpes viruses are smaller than bacteria and can invade anywhere in the human body and cause symptoms such as rashes. It is highly contagious, and as the days pass, the virus multiplies, and it takes a long time for symptoms to improve. The active ingredient in Zovirax 400mg is acyclovir.

Acyclovir can lead to early improvement by suppressing the activity of the pathogenic virus and calming the symptoms. Herpes is said to take about 2-3 weeks to heal naturally, but if you take Zovirax 400mg, you can heal in as little as a week.

The most important thing is to take Zovirax 400mg as soon as herpes develops without leaving it unattended. By taking it at an early stage when the virus is still low, you can expect a higher therapeutic effect and lead to early healing.

Easy to use with a wide variety of dosage forms (tablets, creams, etc.)

One of the features of Zovirax 400mg that is easy to use is that it comes in a wide variety of dosage forms, which is another reason why Zovirax 400mg is chosen as a herpes treatment drug. Typical dosage forms include tablets, ointments, and creams, which are used according to symptoms. In particular, ointments, creams, and other ointments are available at pharmacies in the city, so it is useful as a familiar remedy for herpes.

However, care must be taken when choosing the dosage form type. It is true that Zovirax 400mg is cheaper in topical form than in tablet form. However, if the virus has invaded the ganglia, the ointment will be less effective than the pill. If it has been a while since the herpes outbreak and the symptoms are not mild, choose the tablet type instead of the ointment so that you can heal quickly.

The action of the active ingredient of Zovirax 400mg, acyclovir

The active ingredient in Zovirax 400mg is acyclovir, which inhibits viral activation and multiplication. Specifically, it inhibits viral DNA replication. This prevents the virus from multiplying and stops the progression of symptoms. Due to its high efficacy, it is a world-famous therapeutic drug called “humankind’s first antiviral drug”. As a precaution, as mentioned above, acyclovir itself does not have the effect of killing the virus, so it must be taken continuously for about 5 to 10 days to prevent the virus from multiplying.
