Acyclovir

What is Acyclovir?

Acyclovir is a non-branded version of Zovirax. Because it’s a generic medication, it’s usually a little cheaper, but the results it offers are exactly the same. Acyclovir is normally prescribed to treat infections caused by the herpes virus. It helps to remove the visible symptoms caused by the infection and leaves your skin looking nice and clear. You might see this medication used to treat other viruses like shingles or chickenpox.

The cream version is usually prescribed to treat cold sores, whereas the tablets are prescribed to tackle herpes or genital herpes directly. You can also get Acyclovir as an injection, but this is usually administered in a hospital.

How does Acyclovir work?

Acyclovir is named after its active ingredient, acyclovir, which acts by inhibiting viral DNA replication. By doing this, it reduces the severity of the infection and stops the virus from spreading.

Although acyclovir won’t cure herpes, it does help relieve the pain and discomfort, and helps the sores (if any) heal faster. As well as treating current outbreaks, Acyclovir can also help prevent future ones.^[1]

What doses of Acyclovir are there?

There are only two dosage options available for Acyclovir. For the tablet version it’s a 200 mg tablet, and for the cream it’s one tube that contains 5% of the active ingredient, acyclovir.

How to take Acyclovir

The 200 mg tablets should be taken five times per day for up to five days to treat a recurring herpes outbreak. The cream can typically be applied around five times per day to the area of the cold sore. If you don’t notice any visible improvements at the end of this period then talk with our doctor for further assistance. 

We always recommend taking this medication as advised by our doctor for the best results. However, if you have any questions you can always refer to the treatments package insert. This should be included in the box with your medication.

How long does it take Acyclovir to work?

Treatment time can vary depending on you and the severity of your infection. You should start to feel the positive effects of Acyclovir within five days of starting your course. If you don’t feel any positive benefits after five days, send our doctor a message. 

What should I do if I make a mistake when taking Acyclovir?

Acyclovir isn’t usually harmful. But you should avoid taking too much of it over several days. If you have taken too much, you should contact our physician or a healthcare professional for further advice as soon as you can. Be sure to bring your product box and leaflet with you if they ask you to visit them for an appointment.  

What if I forget to take Acyclovir? 

• If you forget to take a dose of Acyclovir 200 mg, just take a tablet as soon as you remember. 
• If you remember once your next dose is due, then just skip the forgotten dose and continue with your treatment as normal. 
• Don’t take a double dose to make up for a missed tablet.
