 Acivir 400 mg (Acyclovir)

Acivir 400 mg tablets are used in the treatment of certain infections with herpes viruses. These include genital herpes, shingles, and chickenpox. The medication contains the main active ingredient called Acyclovir. This drug may not be appropriate for everyone, and its use should be thoroughly discussed with your doctor.

Acivir does not cure herpes. However, it does reduce pain and may help the sores caused by herpes to heal faster. It also keeps new sores from forming and decrease the intensity of pain and itching. Moreover, in people with a weakened immune system, this antiviral drug can increase the risk of spreading the virus to other parts of the body. Genital herpes is a sexually transmitted disease. To reduce the chance of infecting your partner, forgo intercourse and other sexual contact while you have sores or any other symptom.

Your doctor may also prescribe this antiviral agent to prevent herpes simplex infections in people with the weak immune system either due to diseases such as AIDs, or medical treatment like steroids, chemotherapy, and bone marrow transplant.

How does Acivir work?

The regular administration of Acivir tablets stops the herpes virus from reproducing and infecting more cells in the body.

The activated pharmaceutical component then blocks the activity of DNA polymerase (A viral enzyme) thus prevents the multiplication of the virus.
