Description

Zovirax is a virostatic (i.e. the drug aimed at combating the viruses). The active substance of this drug is Acyclovir. The mechanism of action of this compound on the viruses is aimed at the cessation of their reproduction. An obvious advantage of Zovirax is its indifference to the healthy cells of the body, non-participation in the normal processes in them. The active components of this drug are accumulated in the cells and prevent the spread of viruses on the neighboring healthy tissues. This medicine is used for the treatment of skin and mucous membranes, affected by herpes virus, including herpes simplex on the lips and genitals, herpes zoster; chicken pox. Zovirax is also used systematically in the treatment of encephalitis, herpes neonatorum, pneumonia, and locally– for the eye herpes.
This drug is available in different pharmaceutical forms for different ways of use: cream, pills and powder for the preparation of injection solution and eye ointment. In the instruction, you can find the recommendations on the standard dosages and duration of treatment courses. Zovirax is so non-toxic and safe for the healthy organs and tissues that it’s contraindicated only to the people intolerant to its components. During the pregnancy and breastfeeding, this drug can be used only on the recommendation of professionals and under their supervision. Sometimes (especially if you use the pills or injections of Zovirax), you can have the following side effects: sickness, headache, vertigo, sleep disorder, liver dysfunction, fever, hair loss, etc. The long-term local application can lead to the skin peeling or irritation. In rare cases, injections cause severe reactions up to coma.
Way of use: the drug is intended only for external use.
It is important to start the treatment as soon as possible, preferably during the prodrome period.
The treatment must last at least 4 days. If the wound doesn’t heal, you can continue using the cream up to 10 days. If the symptoms of the disease don’t disappear within 10 days of treatment, you should go to the doctor.

Contraindications

Hypersensitivity to acyclovir and other components of the drug, as well as to Valacyclovir.

Side effects

Some patients can have temporary acute or burning pain. About 5% of patients noted minor dryness and peeling skin. A small part of patients noted erythema and itching. There were also rare cases of contact dermatitis. According to the results of sensitivity tests, the cases were mostly related to the components of creamy base, and not acyclovir. There were isolated reports of immediate hypersensitivity reactions, including angioedema, owing to the local application of acyclovir.
