What is aciclovir and what is it used for?

Aciclovir is an anti-viral medication that is used to treat various infections such as genital herpes, cold sores and shingles caused by the herpes virus. DrFelix supplies the prescription strength Aciclovir tablets for the treatment of genital herpes and cold sores.

What is genital herpes?

Genital herpes is a condition that is caused by the same virus that causes cold sores – the herpes simplex virus (HSV). Genital herpes is considered a sexually transmitted infection (STI), although it is also possible to contract the virus via skin-to-skin contact, without having intercourse.

Is there a cure for genital herpes?

Unfortunately, there is no cure for genital herpes. Once you contract the virus, it stays in your body and lies dormant, causing chronic symptoms that may flare-up from time to time. When treated in a timely fashion, these symptoms can be effectively managed with aciclovir tablets or valaciclovir. However, it is extremely important that you tell your partner about your diagnosis so that he or she may also get tested and treated.

How do I know if I’m having symptoms of genital herpes?

Genital herpes causes cold sore-like blistering of the genitals, which can be quite painful. Like with cold sores, the blisters and sores are highly contagious when present, and the virus is very easily spread from partner to partner. Most often, a first outbreak of HSV is the most severe outbreak a patient will experience, with outbreaks lessening in frequency and intensity as more time passes.

How do I take aciclovir?

Aciclovir is an anti-viral drug that keeps the virus from multiplying too quickly, keeping your symptoms under control. It is important to understand that aciclovir cannot clear your body of HSV. The usual HSV treatment with aciclovir is one 400 mg tablet three times a day for five days. Some patients may take aciclovir at a lower dose over a longer period of time as suppressive therapy. The dosage for preventative treatment of the herpes virus is one tablets two times per day over a few weeks or even months depending on your situation.

Things to know before you start taking aciclovir tablets:

  • Discuss any vaccinations you may be planning on getting with your doctor – you should not get certain immunizations while taking aciclovir.
  • If you are pregnant, breast-feeding, or actively trying to have a baby, make sure you mention this during your consultation.
  • It is best to take aciclovir with lots of water; aciclovir can make you more prone to dehydration.
  • You should limit or avoid alcohol while you are taking aciclovir.
  • If you take any other medications, it is important to tell the doctor during your consultation, as some medications can interact with aciclovir.

What are some of the side effects of aciclovir?

Some of the less serious side effects of aciclovir include stomach cramps, diarrhoea, and headache. However, if you experience any of the side effects below, you should seek medical help.
  • Severe dizziness or drowsiness
  • Back Pain
