How are aciclovir tablets taken?
You need to take each aciclovir tablet with plenty of water. You can take it with or without food, whichever you prefer. If you are having trouble swallowing the tablet, you can disperse it in a glass of water and drink it.
Which dosage do I need to take?
The exact dosage you require depends on your general health, your age and whether you are using Aciclovir to treat a current outbreak or prevent them from happening.
There are two options for treating an outbreak that has already started:
- a high dose, 2 day course of treatment
- a 5 day course
For the 2 day course you take two 400mg tablets, 3 times a day for 2 days.
For the 5 day course you take one 400mg tablet, 3 times a day for 5 days.
Both treatments are equally effective, but if you experience side effects, these might be more likely with the high dose course.
The treatment is also different if this is the first time you have ever had an outbreak. In this case you might need to take a longer course of treatment - one 400mg, 3 times a day for up to 10 days.
If you are taking aciclovir as a preventative measure you need to take 2 tablets per day over a longer period of time (usually 6 to 12 months). Depending on the success of your therapy you may need to continue the treatment over several weeks or even months.

Aciclovir is an antiviral medication used to treat genital herpes caused by the herpes simplex virus (HSV-1 or HSV-2). Aciclovir is a prescription only medication, which can be taken to treat an acute herpes outbreak or prevent genital herpes episodes recurring. Dosage and duration of the treatment depend on whether you are taking aciclovir as a preventative measure or to treat acute symptoms. Once you have been infected with herpes, the virus will remain in your body for the rest of your life. However, aciclovir can help you live with the condition by reducing or preventing outbreaks.
You can test to see if you have herpes using our home test kit.
Aciclovir is an antiviral medication. It inhibits a particular enzyme involved in the virus’s reproduction, thus preventing it from multiplying. As a result, your immune system is able to contain the virus and fight the infection. Aciclovir is also used to treat cold sores (caused by herpes simplex HSVI), chicken pox and shingles (also known as herpes zoster). Zava only prescribes aciclovir as treatment for genital herpes and cold sores.
Prior to beginning a course of aciclovir, you should take the time to read the patient leaflet carefully. During treatment it is important to drink plenty of water, as aciclovir increases your risk of dehydration. The higher the dosage, the more important it is that you watch out for symptoms of dehydration.
Aciclovir can cause drowsiness in some patients. Make sure you do not operate any machinery or drive a car while feeling sleepy under the influence of aciclovir.
There is little information on how aciclovir affects babies during pregnancy or breastfeeding. If you are suffering from genital herpes during pregnancy or after birth, please consult your GP. Please note, that Zava is not able to treat pregnant women.
Unlike bacterial infections, viral infections can be impossible to eradicate entirely. Once you carry the herpes simplex virus you may suffer recurring outbreaks, especially if your immune system is weakened. This does not mean that you will forever be dealing with herpes symptoms, it just means that the condition may return. If you repeatedly encounter recurrent bouts, you may need to take aciclovir to prevent them. This is the case if you suffer more than 6 outbreaks in 12 months or if your outbreaks are less frequent but very severe. You should also try to live as healthily as possible to maintain a healthy immune system.
If you are suffering from kidney disease, you must consult your GP prior to taking aciclovir tablets. Patients with a reduced kidney function require a lower dosage for treating herpes outbreaks. Your doctor will be able to tell whether the benefits of taking aciclovir outweigh the risks in your case and which dosage to take.
You should always follow your doctor’s instructions with regards to the treatment duration. It’s important that you finish your course, especially if you’re treating an acute outbreak (otherwise the symptoms are likely to return).
If you’re taking suppression treatment to prevent outbreaks and would like to try stopping the treatment, you can do so. Usually it’s advised to take the treatment for at least 6 to 12 months before stopping, to allow the medication time to suppress the virus. It’s possible to have an outbreak straight away after stopping, so you may wish to have some treatment to hand so that you can start taking it as soon as you notice symptoms.
