Treatment Options

Aciclovir tablets vs Aciclovir cream

Aciclovir can be used both as a topical cream - which is available to buy over the counte -, or as an oral medication - which is only available on prescription. Aciclovir cream is usually sufficient treatment for cold sores, but should not be used inside the vagina, mouth or eyes.

Non-prescription alternatives

Use of non-prescription Aciclovir cream can help treat the irritation caused by genital herpes, as can the following measures which you can take as home:

  • Gently cleanse the area with warm salt water to help prevent further infection
  • Apply an ice pack wrapped in a flannel to the area, which can help soothe the burning sensation. Never apply an ice pack directly to the area.
  • Before urinating, apply a mild local anaesthetic or vaseline to ease burning. You can also try pouring warm water over your genitals whilst urinating.
  • Wash your hands regularly with soap and hot water, particularly before and after applying Aciclovir cream to the affected area. 
  • Avoid wearing tight clothing, and instead choose loose fitting clothes such as skirts and loose trousers. 
  • Avoid having sex until symptoms have cleared completely.
  • If you think you might have genital herpes, you should get tested as soon as possible.

Can Aciclovir treat shingles?

Aciclovir can be used to treat shingles, which is caused by the herpes zoster virus. For treating shingles, Aciclovir is most effective in tablet form and helps slow down the progress of the shingles rash if taken within the first 72 hours of experiencing symptoms.
