Where is Acyclovir used?

Acyclovir is used for the treatment of certain virus infections. This is used for infections that are initiated by herpes viruses such as:

  • Cold sores
  • Chickenpox
  • Genital herpes
  • Shingles

Acyclovir belongs to the class of medications called antivirals that helps lessen the total of future episodes in people with recurrent outbreaks. This helps slow the development of the virus in your body. The Food and Drug Administration (FDA) approved this medication in the year 1980.


How does Acyclovir work?

Acyclovir works by taking down the capability of the herpes virus to increase and grow in your body. This is an artificial acyclic purine nucleoside analog which is a substrate with a top degree of specificity for herpes simplex.

This medicine is selectively altered to its active system in herpes virus-infected cells. It is also especially taken up by these cells. The inhibition of the virus decreases the period of viral shedding. It restricts the level of pathology, degree of spread, and thus facilitates healing. Acyclovir aborts episodes of recurrent herpes due to inhibition of viral replication following reactivation.

How is Acyclovir taken?

The recommended dosage for this medication is based on your medical condition and response to the treatment. In children, the dosage is based on weight. This medicine is usually taken 2 to 5 times a day by mouth, with or without a meal or snack. This will work best if taken at the first sign of an outbreak. It might not work as well if you delay the treatment.

This drug works best if the amount of it in your body is kept at a constant level. Take this medicine at evenly spaced intervals. Take each dose at the same time each day to help you remember. Continue taking Acyclovir until the entire prescription is finished. Do not skip any doses, change your dose, or stop this too early without consulting your doctor. If your condition does not improve or if it gets worse, let your doctor know right away.
