Herpes labialis Genital herpes infection Herpes Simplex Virus Infections Shingles
VIROvir 500 Tablet is an antiviral medication. It prevents the multiplication of virus in human cells. This stops the virus from producing new viruses and clears up your infection.
Take this medicine in the dose and duration as advised by your doctor. Swallow it as a whole. Do not chew, crush or break it. VIROvir 500 Tablet may be taken with or without food.
Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.
If you miss a dose of VIROvir 500 Tablet, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular schedule. Do not double the dose.
An overdose of this medicine can cause confusion, kidney injury and fits. Do not wait for symptoms to appear — go to the nearest emergency department and take the pack or strip with you.

Antivirals work best when started early — within the first day or two of symptoms for most infections. Complete the course exactly as prescribed; stopping early can allow the virus to become resistant. Drink plenty of water, particularly with aciclovir and its relatives. Treatment for chronic hepatitis must never be stopped without your specialist's advice.
Not for anyone with a known allergy to this medicine or to any ingredient in the pack.
Several antivirals interact with other medicines — tell your doctor everything you take, including supplements.
Store below 30°C in the original pack, away from direct sunlight and moisture. Keep out of the reach of children.
Do not skip any doses and finish the full course of treatment even if you feel better. Drink plenty of water while on treatment with this medicine. This helps to prevent dehydration and kidney damage. If you have genital herpes, use barrier methods (condoms) for contraception and avoid sexual contact while the sores are present. Inform your doctor if you are pregnant or planning to conceive or breastfeeding.
