Acyclovir FAQs

Cold sores are small, fluid-filled blisters that appear on the face — usually around the lips and mouth. 50% of US adults get cold sores at some point.
Cold sores are caused by the herpes simplex virus (HSV). This virus is extremely common, and is caught through contact with an active infection. For most of your life, the virus will be suppressed by your immune system and remain dormant in your skin. It can reactivate at any time, though, replicating and causing a cold sore. The reasons for this are unclear, but many factors are known to trigger it, including illness, hormonal changes and even bright sunlight.
Antiviral medicines stop the herpes simplex virus from replicating, clearing up the infection that causes cold sores.
Acyclovir is an antiviral medicine used to treat cold sores in adults. It works by stopping the virus from replicating. Since the virus replicates very early in the infection, acyclovir works best when you take it as soon as symptoms first appear. If you have frequent outbreaks of cold sores, you can also take it as a suppression treatment to help prevent future flare-ups.
Acyclovir stops the virus reproducing, makes flare-up milder and shorter, and prevents outbreaks by 70-80%.
To treat an outbreak of cold sores, take two 400mg tablets, three times a day, for two days. For suppression treatment, take one 400mg tablet twice a day.
Acyclovir and valacyclovir are similar antiviral medicines. When you take valacyclovir, your body must convert it into acyclovir to get the benefits. There are advantages to both medications; valacyclovir can be more convenient as it doesn’t need to be taken as frequently, while acyclovir is more cost-effective, especially as a suppression treatment. They’re both effective treatments for cold sores.
Acyclovir is the active ingredient in Zovirax, and the name of the generic, unbranded tablet. Both treatments are medically identical, but Zovirax costs more because of the premium brand name.
Like all medications, acyclovir can cause side effects. These include headaches, dizziness, nausea, vomiting, abdominal pains and fatigue.
You don’t need an existing prescription to purchase acyclovir from ZipHealth. Take our simple online consultation and our medical team will prescribe your treatment for you. Your medication will be sent directly to you from our partner pharmacy.
