Aciclovir 400mg Tablets information

What is Aciclovir and what is it used for?

Aciclovir is an antiviral tablet, which is used to prevent or treat infections from the herpes simplex virus (HSV), which can cause both cold sores, typically seen around the mouth, and genital herpes that can appear in and around the genitals and anus. Read more about what aciclovir is used for here.

Aciclovir tablets are a generic brand containing the active ingredient aciclovir. The branded version of this medicine is Zovirax. It is cheaper to buy here in its non-branded form, but equally as effective.

It cannot completely cure herpes but will stop the growth of the virus and suppress the symptoms. Aciclovir can also be used as a means to prevent recurrent outbreaks. It is one of the most popular treatments in the UK for genital herpes.

How does Aciclovir work?

If you begin to take Aciclovir 400mg as soon as symptoms appear, the outbreak will often disappear within 1-2 days. Recurrent outbreaks are usually preceded by a tingling or itching sensation.

Aciclovir targets the enzyme that is necessary for the HSV to replicate and grow. By stopping further production of this enzyme, the virus cannot reproduce and create more blisters. This allows the immune system to fight the remaining virus and end the outbreak.

After taking Aciclovir, you should wait until the affected area has healed before resuming sexual activity. Once the virus has fully gone into remission, it will no longer be contagious.

Alternatives to Aciclovir

Aciclovir tablets are a prescription-only treatment for genital herpes. Other prescriptions, antiviral treatments include; Valtrex and the generic branded version that includes the same active ingredient, Valaciclovir.

If you do not fancy using prescription medications to help ease your symptoms or you want to try some non-medicinal alternative treatments alongside Aciclovir, helpful things to try include:

  • Cleaning the area with water or saltwater to promote healing
  • Avoid wearing tight clothing
  • Use pain relief such as paracetamol
  • Try to avoid your known outbreak triggers such as excess alcohol.
  • Use Vaseline on the blisters to promote healing and relieve pain.

Aciclovir dosage

Begin taking Aciclovir 400mg tablets as soon as you notice symptoms of the herpes virus, which include visible blisters and a burning sensation.

  • Take 1 tablet three times a day for 5 days, or for as long as is prescribed with a glass of water. If you are taking Aciclovir to prevent future recurrences of herpes, you will likely be prescribed 2 tablets per day for a period of 3-6 months.

HSV infections are contagious and can be spread even if you are taking Aciclovir. So, be sure to frequently wash your hands and do not allow the infected area to make contact with others.

You can find out more about correct Aciclovir dosages here.

What is Genital Herpes?

Genital herpes is a common infection that causes painful blisters on the genitals and nearby areas, caused by the herpes simplex virus (HSV).

Genital herpes is most often transmitted through sexual contact, and so is commonly classified as a sexually transmitted infection (STI). Like many STIs, HSV is highly contagious and can be spread by any direct contact with the affected areas.

Once you contract the herpes virus, you cannot cure the virus completely; however, you can use antiviral medication to treat symptoms and keep outbreaks at bay.

Read more in our helpful How Can You Get Genital Herpes guide.

Are cold sores the same as herpes?

Cold sores and genital herpes are both caused by the herpes virus, but they are caused by different strains of the virus. Small blisters appear on the lips and face as cold sores, caused by the herpes simplex virus-1 (HSV-1). The HSV-2 virus causes genital herpes, which is spread through sexual contact. Both HSV-1 and HSV-2 can cause mouth and genital sores.

Learn more about the differences between cold sores and genital herpes in our detailed guide.

How can women catch genital herpes?

While genital herpes is more commonly transmitted from men to women than from women to men, anyone can contract genital herpes through skin-to-skin contact.

Skin-to-skin contact is typically caused by sexual transmissions. Women can catch genital herpes by:

  • Vaginal sex
  • Anal sex
  • Oral sex
  • Non-penetrative genital contact
  • Infection spread through the fingers
  • Sharing of sex toys

Herpes genitalis is most commonly transmitted through vaginal, oral or anal sex. As with most sexually transmitted infections, having multiple sexual partners will increase your risk of contracting the virus.

Genital herpes is highly contagious and easily transmitted. You can pass on the STI at any stage of the virus (from tingling at the start of a new outbreak to when sores heal), and you can also pass the virus on even if you don't have any symptoms.

What are the symptoms of genital herpes?

In some cases of genital herpes outbreaks, you won’t experience any symptoms at all, but you can still be contagious. More commonly, you will notice changes in the affected area around 2 to 12 days after exposure to the virus.

Common symptoms of genital herpes include:

  • Small blisters around the genitals that burst and leave open sores.
  • Red bumps.
  • Itching, pain or tenderness in the genital area.
  • Bleeding or oozing ulcers.
  • Pain when urinating.
  • Unusual vaginal discharge.

Sores may appear differently depending on where they crop up on your body. They often occur in the following areas:

  • Buttocks and thighs
  • Anus
  • Mouth
  • Urethra
  • Vagina or penis
  • scrotum

If you do notice signs of the condition, no matter where it appears, it’s important to seek a genital herpes treatment to reduce symptoms and prevent further outbreaks.

Is genital herpes curable?

While there is no cure for herpes, the virus's severity varies over the course of a person's lifetime. Over time, recurrent genital herpes outbreaks generally become less frequent and less severe, but it is still important to monitor your symptoms with antiviral medication if symptoms do come back.
