Effectiveness

How Zovirax Affects PatientsAcyclovir works by blocking the action of viral DNA polymerase and stopping the replication of herpesviruses. It is considered to be a relatively safe drug with a wide range of therapeutic uses, and it is rare for patients to experience an overdose.
How Zovirax works in the bodyAcyclovir works by stopping the virus from replicating its DNA. Acyclovir is converted to an active form in the virus, and then attaches to the virus' DNA polymerase. This attachment prevents the virus from being able to use the polymerase to make more copies of its DNA, stopping the virus from replicating. In some cases, the attachment is so strong that it completely shuts off the virus' DNA polymerase, stopping the virus from replicating completely.

When to interrupt dosage

The suggested measure of Zovirax is contingent upon the diagnosed affliction, including Cytomegalovirus Infections, severe Genital herpes and Herpes simplex type I reactivation. The dosage fluctuates as per the technique of delivery (e.g. Cream - Topical or Injection, powder, lyophilized, for solution - Intravenous) outlined in the following table.

Zovirax for Recurrent Cold Sore
I've been using this for years and it really does help to stop or reduce symptoms. However, it does become less effective over time, so if you find that an old tube isn't working as well, get a new one.

Zovirax for Recurrent Cold Sore
I apply this product to my lips when needed in order to prevent any cold sore outbreaks. It's not a perfect solution, but it's the best one I've found so far.

Zovirax for Recurrent Cold Sore
Despite being quite expensive, this prescription didn't work for me. Additionally, I had to squeeze the tube extremely hard in order to get any medication out. Not sure if this is because it wasn't filled completely or if they put it in a larger tube to make you think you are getting more.

Zovirax for Recurrent Cold Sore
I did not see any results from using this product, and it actually made the situation worse. I stopped using it after a few days and applied an Aloe-based gel instead - which cleared up the issue within four days.

What is Zovirax used to treat?

Answered by AI

"Zovirax Cream is a medication used to treat the symptoms of cold sores and genital herpes. It may be used alone or with other medications. Zovirax Cream belongs to a class of drugs called antivirals."

Answered by AI

Can you buy Zovirax over the counter?

"Acyclovir (Zovirax) is not available over the counter in the United States. It is only available with a prescription. Abreva is a good option if you are looking for an (OTC) medication for cold sores."

How long does it take Zovirax to work?

"It may take up to two hours for the plasma concentration of acyclovir to peak after it is taken orally. However, the symptoms may only start to reduce after three days. It is best to start taking acyclovir within 48 hours of the first symptoms appearing. Acyclovir should be taken until the full course prescribed is completed."
