Product Description

Acyclovir is antiviral medicine which inhibits the active stage of the replication of herpes virus.

Herpes virus can be in the human cells for a long time and does not cause any symptoms. As soon as the protective function of the body are reduced, the cells will produce virus and the human will have the symptoms.

Acyclovir prevents the synthesis of the herpes virus in the cells during the reduction of the protective functions of the body and helps to improve the immunity for more stable resistance to the herpes virus.

In case of the regular use of Acyclovir for the purposes of the prevention of herpes virus, the frequency and intensity of the relapses are reduced, and the symptoms pass quickly.

The use of Acyclovir during the acute condition of the herpetic infection helps to accelerate the process of healing of the skin and mucous membranes, regeneration of the tissues, and to reduce itching and pain in the area of the rash.

Acyclovir provides a selective action and neutralizes only herpes virus despite a strong antiviral activity.
