Aciclovir

What is Aciclovir and how does it treat cold sores?

Aciclovir is an antiviral medication used to treat the herpes simplex virus and other closely related viruses, such as chicken pox or shingles. It stops the spreading of the herpes virus in the body by interrupting the process of virus replication thereby reducing the duration of the infection. It is not a cure for these infections, as the virus continues to live in the body even after an outbreak but Aciclovir reduces the severity and length of the outbreak.

How do I take Aciclovir?

Aciclovir should be swallowed with water three times a day for 5 days. The treatment is most effective when you use it at the first signs of outbreak.

How effective is Aciclovir?

If Aciclovir taken as soon as a herpes outbreak has begun, Aciclovir can reduce the duration and severity of the outbreak. It can also suppress recurring outbreaks by 80%.

How fast does it work?

How quick and well Aciclovir work will depend on the severity of your symptoms and how soon you notice the symptoms before starting treatment. As soon as you start to notice the symptoms, it is best to start taking Aciclovir. You should consult with your doctor as soon as you spot an outbreak.

Do I need to seek medical advice before taking Aciclovir?

If you are pregnant, breastfeeding, elderly or suffer from kidney problems it is best to seek medical advice before taking Aciclovir.
