What is Aciclovir?

This medicine is one of the most commonly used antiviral medications used to treat genital herpes (herpes simplex strain 2, HSV-2), cold sores (herpes simplex strain 1, HSV-1) chicken pox and shingles (herpes zoster). It is an oral prescription in the form of capsules that can offer relief from unpleasant symptoms within 24 hours as well as significantly reducing the duration of your outbreak.

Aciclovir can help to stop infections from getting worse and can also help to reduce the chances of an infection returning, making it a preventative treatment useful for those who find certain triggers can prompt the virus such as a weakened immune system or certain times of the month.

This medication is a proven way to treat and prevent outbreaks of the sexually transmitted infection (STI) genital herpes as well as cold sores and shingles, having been clinically tested and requiring a prescription in the UK that is available to buy from euroClinix in dosages 200mg and 800mg. The sooner you take it after you've noticed the first signs of an outbreak, the better it will be at cutting down recovery time and minimising the occurrence of uncomfortable symptoms, which is why we offer next day delivery free of charge for all orders made before 4.30pm. This medication can also be used to suppress the virus and prevent outbreaks, especially in people who experience frequent genital herpes infections. This is most likely in the first two years of contracting genital herpes as outbreaks are more frequent at the beginning of the infection (up to five times over two years).

To buy Aciclovir online from euroClinix, and anywhere in the UK, you must complete an online consultation. The consultation will be reviewed by one of our doctors, to ensure that this prescription medication is suitable for you before dispatching straight to your door.

How does Aciclovir work?

These antiviral tablets work by directly attacking the herpes simplex virus to prevent it from spreading. It does this by influencing the DNA polymerase enzymes that are vital when helping the virus duplicate and increase, which results in fiercer symptoms and prolonged infection. This allows your body's immune system to combat the STI or viral infection effectively.

This is why taking this treatment when the infection hasn't been active for a long time is so important. At maximum effectiveness, Aciclovir will reduce the infection to around one week and significantly decrease the problematic symptoms within one day, resulting in minimum disturbance to your life.

Depending on the viral infection you are using Aciclovir for will depend on the speed and efficiency of the tablet and the dosage will also vary, following doctor's instruction.

How to take Aciclovir

Aciclovir tablets are obtainable in a hard capsule format to buy at euroClinix to treat herpes simplex and other viral outbreaks, but a cream or ointment is also available if that is your preferred option. Another alternative is to use Aciclovir tablets with a compatible jelly or cream, and to follow other self-help pointers detailed on our genital herpes information page.

Aciclovir is taken in different doses in a different quantity, depending on the strain of herpes virus it's required to treat. Although a doctor may adjust the dosage slightly, below is the guideline to follow. This may also alter depending on whether you are taking Aciclovir as a preventative or needs-be basis. For further information on dosage option and which is most appropriate for particular strains of the herpes virus, the patient leaflet is attached at the bottom of this page:

  • For genital herpes and cold sores, the general prescribed dose would be one 200mg Aciclovir tablet five times a day, at four hourly intervals for a duration of five days.
  • As a preventative treatment for genital herpes and cold sores, one Aciclovir 200mg tablet should be taken four times a day at six-hour intervals for six to twelve months.
  • One 800mg Aciclovir tablet (or four 200mg tablets) five times a day at four-hour intervals for seven days is usually recommended for the treatment of shingles.

Whilst these are usual recommendations for genital herpes, cold sores and shingles, your doctor will prescribe the most convenient dosage and daily quantity for you.

Aciclovir dosages

Aciclovir is available to buy from euroClinix in two dosages; 200mg and 800mg. The 200mg dose is more frequently used, as it is a lower dosage, which can be taken multiple times throughout the week with minimal risk of side effects. The 800mg is usually prescribed to people with shingles, or severe bouts of the herpes virus.

A dosage of 400mg is also available to treat genital herpes and cold sores, however a lower dose of 200mg is effective for the majority of people and a higher dosage taken daily has an unnecessary risk of side effects. If you are prone to particularly severe outbreaks of herpes, 400mg can be ordered.

Precautions of Aciclovir

Aciclovir tablets may not be entirely suitable to take if you are currently pregnant or breastfeeding, but do book a face-to-face appointment if you are expecting to rule this out completely. You should also not take it if you are diabetic or taking medicines such as Zidovudine, Ciclosporin or Cimetidine.

During your online consultation, make sure that you mention any medical conditions or medications you are taking that may be relevant, whether they were mentioned in this section or not.

Aciclovir side effects

Just like all prescription medications, Aciclovir can cause side effects, however, this is generally rare and if so, the side effects tend to be manageable especially in comparison to the symptoms of the virus itself.

Side effects are additionally unlikely as it's mostly used as a short-term treatment most of the time so any reactions that occur subside quickly. Common effects include headaches, diarrhoea, stomach pains, rashes, dizziness and fatigue. If you develop any more serious effects or these effects won't go away, then you should seek medical advice form your doctor as soon as possible.
