What is in this leaflet

This leaflet answers some common questions about Voltaren Suppositories. 

It does not contain all the available information.

It does not take the place of talking to your doctor or pharmacist.

All medicines have risks and benefits. Your doctor has weighed the risks of you taking it against the benefits they expect it will have for you.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

Keep this leaflet with the medicine. You may need to read it again.

What Voltaren is used for

Voltaren relieves pain and reduces inflammation (swelling and redness) that may occur in the following:

  • different types of arthritis including rheumatoid arthritis and osteoarthritis
  • other painful conditions where swelling is a problem such as back pain, rheumatism, muscle strains, sprains and tendonitis (eg. tennis elbow)
  • menstrual cramps (period pain)
  • migraine attacks

Voltaren belongs to a family of medicines called non-steroidal anti-inflammatory drugs (NSAIDs). These medicines can relieve the symptoms of pain and inflammation but they will not cure your condition.

Your doctor may prescribe Voltaren for another purpose.

Ask your doctor if you have any questions about why it has been prescribed for you.

Voltaren is only available with a doctor's prescription. It is not addictive.

Before you take Voltaren

When you must not take it

Do not take Voltaren if you have an allergy to:

  • diclofenac (the active ingredient in Voltaren) or any of the other ingredients listed at the end of this leaflet
  • other medicines containing diclofenac (eg.Voltaren Emulgel)
  • aspirin
  • any other NSAID medicine

Many medicines used to treat headache, period pain and other aches and pains contain aspirin or NSAID medicines. If you are not sure if you are taking any of these medicines, ask your pharmacist.

Symptoms of an allergic reaction to these medicines may include:

  • asthma, wheezing or shortness of breath
  • swelling of the face, lips or tongue which may cause difficulty in swallowing or breathing
  • hives, itching or skin rash
  • fainting

If you are allergic to aspirin or NSAID medicines and take Voltaren, these symptoms may be severe.

Do not take Voltaren if at the present time you have an ulcer (gastric or duodenal) or bleeding from the stomach or bowel.
If you take it, your stomach problem may become worse.

Do not use Voltaren suppositories if you suffer from inflammation of the rectum (back passage).

Do not take Voltaren after the expiry date (EXP) printed on the pack.
It may have no effect at all, or worse, an entirely unexpected effect if you take it after the expiry date.

Do not take Voltaren if the packaging is torn or shows signs of tampering.

Do not give Voltaren to children less than 5 years.

If you are not sure whether you should start taking Voltaren, contact your doctor.

Before you start to take it

Tell your doctor if you are allergic to any other medicines, foods, dyes or preservatives.
Your doctor will want to know if you are prone to allergies.

Tell your doctor if, in the past, you have ever had:

  • ulcers (gastric or duodenal)
  • severe attacks of indigestion or other stomach trouble
  • diseases of the bowel (eg. Crohn's disease, ulcerative colitis)
  • bleeding from your rectum (back passage)

Tell your doctor if you have any of these health problems/medical conditions at the present time:

  • heart disease
  • kidney disease
  • liver disease
  • high blood pressure
  • a tendency to bleed or other blood problems such as anaemia
  • asthma
  • haemorrhoids (piles) or irritation of the rectum (back passage)

Your doctor may want to take special precautions if you have any of these conditions.

Tell your doctor if you have an infection at the present time.
If you take Voltaren while you have an infection, some of the signs of the infection may be hidden (pain, fever, swelling, redness). You may think, mistakenly, that you are better or that the infection is not serious.

Tell your doctor if you are pregnant or are breast-feeding.
Like most NSAID medicines, Voltaren is not recommended for use during pregnancy or breast-feeding. Your doctor will discuss with you the benefits and risks of taking it.

Taking other medicines

Tell your doctor if you are taking any other medicines, including any that you buy without a prescription from a pharmacy, supermarket or health food shop.

Some medicines that are important to mention include:

  • aspirin, salicylates or other NSAID medicines
  • warfarin, a medicine used to stop blood clots
  • digoxin, a medicine for your heart
  • lithium, a medicine used to treat some types of depression
  • diuretics, also called fluid or water tablets
  • tablets used to treat diabetes
  • methotrexate, a medicine used to treat arthritis and some cancers
  • cyclosporin, a medicine used to suppress the immune system
  • certain antibiotics called quinolones

Your doctor or pharmacist has more information on medicines to be careful with or avoid while taking Voltaren.

If you have not told your doctor about any of these things, tell them before you take Voltaren.

How to take Voltaren

Follow all directions given to you by your doctor and pharmacist carefully.
These instructions may differ from the information contained in this leaflet.

If you do not understand the instructions on the label, ask your doctor or pharmacist for help.

How much to take

  • For arthritis or other painful conditions where swelling is a problem:

Your doctor may start your treatment with anywhere from 75mg to 150mg per day, depending on your situation. After the early stages of treatment it is usually possible to reduce the daily dose to 75mg to 100mg per day.
12.5mg and 25mg suppositories are for use in children over 5 years of age and weighing 18kg or more with chronic juvenile rheumatoid arthritis.

  • For menstrual cramps (period pain)

At the start of treatment the daily dose is usually between 50mg and 100mg. If necessary, it can be raised over several menstrual periods to a maximum of 200mg each day.

  • For migraine attacks

At the first signs of an impending attack the starting dose is usually 100mg. Your doctor may give you additional doses up to 100mg on the same day if required. If you require further therapy on the following days your doctor will give you up to 150 mg in divided doses depending on your situation.

How to take it

Voltaren suppositories are usually used at bedtime to relieve pain during the night and early morning stiffness.

If possible, go to the toilet and empty your bowels before using the suppository.
They work best if your bowels are empty.

Follow these steps:

  • Wash your hands thoroughly with soap and water.
  • If the suppository feels soft, chill it BEFORE removing the wrapper by placing it in the fridge or holding it under cold water for a few minutes.
  • Put on a disposable glove, if desired (available from a pharmacy)
  • Remove all of the wrapper from the suppository.
  • Moisten the suppository by dipping it briefly in cool water.
  • Lie on your side and raise your knees to your chest.
  • Push the suppository, blunt end first, gently into your rectum (back passage).
  • Remain lying down for a few minutes so that the suppository dissolves.
  • Wash your hands thoroughly.

Try not to go to the toilet and open your bowels for at least one hour after using the suppository.
The suppository takes about one hour to be completely absorbed and do its work.

If you are not sure how to use a suppository, ask your doctor or pharmacist.

How long to take it

Do not take Voltaren for longer than your doctor says.

If you are taking Voltaren for arthritis, it will not cure your disease but it should help to control pain and inflammation. It usually begins to work within a few hours but several weeks may pass before you feel the full effects of the medicine.

For menstrual cramps (period pain), the suppositories are usually taken during each period as soon as cramps begin and continued for a few days until the pain goes away.

If you forget to take it

If it is almost time for your next dose (eg. within 2 or 3 hours), skip the dose you missed and take the next dose when you are meant to.

Otherwise, take it as soon as you remember, and then go back to taking it as you would normally.

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

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

If you take too much (Overdose)

Immediately telephone your doctor or National Poisons Information Centre, Dunedin (phone 0800 POISON or 0800 764 766), or go the Accident and Emergency Department at your nearest hospital if you think that you or anyone else may have taken too much Voltaren. Do this even if there are no signs of discomfort or poisoning.

Keep the telephone numbers for these places handy.

While you are taking Voltaren

Things you must do

If you become pregnant while taking Voltaren, tell your doctor immediately.
Your doctor can discuss with you the risks of taking it while you are pregnant.

If you are about to be started on any new medicine, tell your doctor and pharmacist that you are taking Voltaren.

Take Voltaren exactly as your doctor has prescribed.
If you do not follow your doctor's instructions, your condition may not improve or you may have unwanted side effects.

If, for any reason, you have not taken your medicine exactly as prescribed, tell your doctor.
Otherwise your doctor may think that it was not effective and change your treatment unnecessarily.

If you feel the medicine is not helping, tell your doctor.
This will help your doctor to determine the best treatment for you.

Be sure to keep all of your doctor's appointments so that your progress can be checked.
Your doctor may want to take some blood tests from time to time. This helps to prevent unwanted side effects.

If you are going to have surgery, make sure the surgeon and anaesthetist know that you are taking Voltaren.
NSAID medicines can slow down blood clotting.

If you get an infection while taking Voltaren, tell your doctor.
This medicine may hide some of the signs of an infection (pain, fever, swelling, redness). You may think, mistakenly, that you are better or that the infection is not serious.

Tell all of the doctors, dentists and pharmacists that are treating you that you are taking Voltaren.

Things you must not do

Do not take any other medicines used to treat arthritis while you are taking Voltaren without first telling your doctor. This includes:

  • aspirin (also called ASA or acetylsalicylic acid)
  • other salicylates
  • other forms of Voltaren
  • any other NSAID medicine

If you take these medicines together with Voltaren, they may cause unwanted effects.

If you need to take something for headache or fever, it is usually okay to take paracetamol. If you are not sure, ask your doctor.

Do not stop any other forms of treatment for arthritis that your doctor has told you to follow.
This medicine does not replace exercise or rest programs or the use of heat/cold treatments.

Do not use Voltaren to treat any other complaints unless your doctor says you can.

Do not give this medicine to anyone else.
It may harm them, even if their symptoms seem to be the same as yours.

Things to be careful of

Be careful driving, operating machinery or doing jobs that require you to be alert until you know how Voltaren affects you.
As with other NSAID medicines, Voltaren may cause dizziness, drowsiness or blurred vision in some people. If you have any of these symptoms, do not drive or do anything else that could be dangerous.

Side effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Voltaren.
This medicine helps most people, but it may have unwanted side effects in a few people. All medicines have side effects. Sometimes they are serious, most of the time they are not. You may need medical treatment if you get some of the side effects.

If you are over 65 years old, you should be especially careful while taking this medicine. Report any side effects promptly to your doctor.
As people grow older, they are more likely to get side effects from medicines.

Do not be alarmed by this list of possible side effects. You may not experience any of them.

Ask your doctor or pharmacist to answer any questions you may have.

If any of the following happen, stop taking Voltaren and tell your doctor immediately or go to the Accident and Emergency Department at your nearest hospital:

  • vomiting blood or material that looks like coffee grounds
  • bleeding from the back passage, black sticky bowel motions (stools) or bloody diarrhoea

Some people may get other side effects of Voltaren.

After using Voltaren


  • Keep your medicine in the original container until it is time to take it.
  • Store the container in a cool dry place.
  • Do not store Voltaren or any other medicine in the bathroom or any other place that is hot or steamy.
  • Do not leave it in the car or on window sills.

Heat and dampness can destroy some medicines. They will keep well if the temperature is cool and dry.

Keep the medicine where children cannot reach it.
A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.


If your doctor tells you to stop taking Voltaren or you find that it has passed the expiry date, ask your pharmacist what to do with any medicine you have left over.
