What dosage of Valaciclovir should I take?

The dose of Valaciclovir you need to take will depend on whether this is the first time you have had an outbreak, if this is a recurring outbreak or if you are taking it to try to prevent outbreaks.

If this is your first outbreak, you should take one 500mg tablet twice a day for 5 to 10 days. If, after the first 5 days you are still getting new sores you can continue to take the tablets for 10 days. Your doctor will advise you of your treatment plan, so it is important to follow their instruction. For recurring outbreaks, the treatment plan is usually the same, but you would only need to take the tablets for 3 to 5 days.

To prevent outbreaks you can use Valaciclovir for suppression, which is where you take one tablet of Valaciclovir 500mg every day for 6-12 months.

If you overdose, you must seek medical assistance.

If you miss a dose, do not double dose the next time. Simply continue with the treatment as normal from the next dose.

You must drink a lot of fluids whilst taking Valaciclovir and wear sun cream as your skin is more sensitive to UV light when taking Valaciclovir.

You can treat genital herpes two ways. One treatment option is for when you experience an individual outbreak (acute therapy) and the other is treatment for when you need to avoid regular outbreaks (suppressive). ZAVA offers both types of treatment through a discreet, convenient service.
