How to take this medicine

Follow carefully all directions given to you by your doctor or pharmacist.

Their instructions may be different to the information in this leaflet.

If you do not understand any written instructions, ask your doctor or pharmacist for help.

How much to take

Your doctor or pharmacist will tell you how many tablets you will need to take. This depends on your condition and whether or not you are taking any other medicines.

The usual dose for adults and children over 12 years of age for CMV is four 500 mg tablets with water, four times a day for 90 days.

How to take it

Swallow the tablets with a glass of water. You should drink plenty of fluids whilst taking valaciclovir, especially if you are elderly.

When to take it

To prevent CMV infection and disease, the tablets should be taken four times a day (i.e. morning, noon, afternoon and evening).

How long to take it for

For the prevention of CMV infection and disease, the usual course of treatment is 90 days.

Continue taking your medicine for as long as your doctor tells you.

Do not stop taking it unless your doctor tells you to – even if you feel better.

Make sure you have enough to last over weekends and holidays.

If you forget to take it

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to. Otherwise, take it as soon as you remember, then go back to taking it as you would normally.

If you miss more than one dose, or you are not sure what to do, ask your doctor or pharmacist.

Do not take a double dose to make up for missed doses. This may increase the chance of side effects.

If you have trouble remembering to take your medicine, ask your pharmacist for some hints to help you remember.

If you take too much (overdose)

If you think that you or anyone else may have taken too much of this medicine, immediately telephone your doctor or the Poisons Information Centre (Tel: 13 11 26 in Australia) for advice. Alternatively go to the Accident and Emergency Department at your nearest hospital.

Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

  • acute renal failure which may present as: decreased urine; fluid retention causing swollen legs, ankles or feet; nausea; drowsiness; fatigue; difficulties breathing.
  • confusion, hallucinations, agitation, decreased consciousness and coma.

  • Go to your doctor regularly for a check-up.
    Your doctor may occasionally do tests to make sure the medicine is working and to prevent side effects.

  • Give this medicine to anyone else, even if their symptoms seem similar to yours.
  • Take your medicine to treat any other condition unless your doctor or pharmacist tells you to.
