All medicines have risks and benefits. Your doctor has weighed the risks of you taking LOVIR against the benefits this medicine is expected to have for you.

What LOVIR tablets are used for

LOVIR tablets contain the active ingredient aciclovir.

Aciclovir belongs to a group of medicines called "anti-virals". LOVIR works by stopping the herpes virus being able to reproduce. The length and severity of an outbreak of herpes is therefore reduced. Long term use of LOVIR can reduce the number of herpes outbreaks in people who experience this condition often. LOVIR does not get rid of the herpes virus from your body.

Your doctor may have prescribed LOVIR tablets for another reason. Ask your doctor if you have any questions about why LOVIR has been prescribed for you.

This medicine is available only with a doctor's prescription.

Using LOVIR tablets

How much to take

Your doctor will decide at what dose and for how long you will need LOVIR tablets.

Your doctor and pharmacist will be able to tell you:

  • how many tablets to take at a time.
  • how many doses a day you are to take.
  • When you are to take each dose.

The usual dose of LOVIR in the treatment of an outbreak of herpes is either one 200 mg tablet every four hours while awake (a total of five tablets daily) or one 400mg tablet twice a day for five or ten days. This dose may be varied by your doctor depending on the response. Your doctor may also vary the LOVIR dosage for other medical reasons.

The usual dose of LOVIR used to treat shingles is one 800mg tablet every four hours while you are awake (a total of five tablets daily) for seven days. However your doctor may vary this dose if you have other medical conditions also.

If you have any questions about the dose that you have been prescribed you should ask your doctor or pharmacist.

How to take LOVIR tablets

LOVIR tablets may be swallowed whole with a glass of water, or dispersed in a quarter of a glass of water (about 50 mL) and then swallowed.

If you forget to take it

If you have forgotten to take more than one dose contact your doctor or pharmacist for advice.

Do not take a double dose to make up for the dose that you have missed.

Taking your medicine at the same time each day may help you to remember to take it regularly. If you have trouble remembering to take your medicine, ask your pharmacist for some hints.
