What Voltaren is used for

Voltaren belongs to a group of medicines called non-steroidal anti-inflammatory drugs (NSAIDs), which are used to treat pain and reduce inflammation (swelling and redness).
Voltaren is used to treat:
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 (e.g. tennis elbow)
menstrual cramps (period pain)
relieve pain in children after they have had an operation.
It can relieve the symptoms of pain and inflammation but it will not cure your condition.
Ask your doctor if you have any questions about why this medicine has been prescribed for you.
Your doctor may have prescribed it for another purpose.
Voltaren is only available with a doctor’s prescription. It is not addictive.
Voltaren suppositories should not be used in children under 12 months of age. Because of their strength, Voltaren 100mg suppositories are not suitable for children and adolescents.
There is not enough information to recommend the use of Voltaren tablets in children.

Before you use Voltaren

When you must not use it

Do not use Voltaren if you are allergic (hypersensitive) to:
diclofenac (the active ingredient in Voltaren) or any of the other ingredients listed at the end of this leaflet
other medicines containing diclofenac (e.g. Voltaren Rapid tablets, Voltaren Emulgel)
any other NSAID
If you are not sure if you are taking any of the above medicines, ask your doctor or pharmacist.
Some of the symptoms of an allergic reaction may include:
shortness of breath
wheezing or difficulty breathing
swelling of the face, lips, tongue, throat, and/or extremities (signs of angioedema)
rash, itching or hives on the skin.
Many medicines used to treat headache, period pain and other aches and pains contain aspirin or NSAID medicines. If you are allergic to aspirin or NSAID medicines and you use Voltaren, these symptoms may be severe.
Do not use Voltaren if you have had any of the following medical conditions:
a stomach or intestinal ulcer
bleeding from the stomach or bowel (symptoms of which may include blood in your stools or black stools)
kidney or liver problems
severe heart failure
heart bypass surgery
Do not use Voltaren suppositories if you suffer from inflammation of the rectum (back passage) or if your rectum is painful (sometimes with bleeding or discharge).
Do not use Voltaren during the first 6 months of pregnancy, except on doctor’s advice. Do not use during the last three months of pregnancy.
Use of this medicine during the last 3 months of pregnancy may affect your baby and may delay labour and birth.
Use of non-aspirin NSAIDs can increase the risk of miscarriage, particularly when taken close to the time of conception.
Do not use Voltaren after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering.
In that case, return it to your pharmacist.

Before you start to use it

Tell your doctor if you have any of the following health problems / medical conditions:
established disease of the heart or blood vessels (also called cardiovascular disease, including uncontrolled high blood pressure, congestive heart failure, established ischemic heart disease, peripheral arterial disease or atherosclerotic cardiovascular disease), as treatment with Voltaren is generally not recommended
established cardiovascular disease (see above) or significant risk factors such as high blood pressure, abnormally high levels of fat (cholesterol, triglycerides) in your blood, diabetes, or if you smoke, and your doctor decides to prescribe Voltaren, you must not increase the dose above 100 mg per day if you are treated for more than 4 weeks.
a past history of ulcers (stomach or intestinal)
gastrointestinal problems such as stomach ulcer, bleeding or black stools, or have experienced stomach discomfort or heartburn after taking anti-inflammatory medicines in the past
diseases of the bowel or inflammation of the intestinal tract (Crohn’s disease) or colon (ulcerative or ischemic colitis)
past history of haemorrhoids (piles) or irritation of the rectum (back passage)
liver or kidney problems
a rare liver condition called porphyria
bleeding disorders or other blood disorders (e.g. anaemia)
asthma or any other chronic lung disease that causes difficulty in breathing
hay fever (seasonal allergic rhinitis)
repeated chest infections
polyps in the nose
dehydration (e.g. by sickness, diarrhoea, before or after recent major surgery
swollen feet
Your doctor may want to take special precautions if you have any of the above conditions.
It is generally important to take the lowest dose of Voltaren that relieves your pain and/or swelling and for the shortest time possible in order to keep your risk for cardiovascular side effects as small as possible.
Tell your doctor if you are pregnant or trying to become pregnant.
There is not enough information to recommend the use of Voltaren during the first 6 months of pregnancy and it must not be used during the last 3 months. Voltaren may also reduce fertility and affect your chances of becoming pregnant. Your doctor can discuss with you the risks and benefits involved.
Tell your doctor if you currently have an infection.
If you use Voltaren while you have an infection, some of the signs of the infection such as pain, fever, swelling and redness may be hidden. You may think, mistakenly, that you are better or that the infection is not serious.
Tell your doctor if you are breast-feeding.
Breast-feeding is not recommended while you are using this medicine. The active ingredient in Voltaren passes into breast milk and may affect your baby.
Tell your doctor if you are lactose intolerant.
Voltaren tablets contain lactose.
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, especially if you get skin reactions with redness, itching or rash.

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:
other anti-inflammatory medicines, e.g. aspirin, salicylates or ibuprofen
warfarin or other “blood thinners” (medicines used to prevent blood clotting)
digoxin (a medicine for heart problems)
lithium or selective serotonin-reuptake inhibitors (SSRIs), a medicine used to treat some types of depression
diuretics (medicines used to increase the amount of urine)

How to use Voltaren

When to take it

Voltaren Tablets
It is recommended to take the tablets before meals or on an empty stomach. If they upset your stomach, you can take them with food or immediately after food.
They will work more quickly if you take them on an empty stomach but they will still work if you have to take them with food to prevent stomach upset.
Voltaren suppositories
Use the suppositories at bedtime to relieve pain during the night and early morning stiffness; or to relieve pain after an operation.

How much Voltaren to take/use

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.
There are different ways to take Voltaren tablets and suppositories, depending on your condition. Your doctor will tell you exactly how many tablets or suppositories to take.
Do not exceed the recommended dose.

To treat arthritis or other painful conditions

The usual starting dose of Voltaren tablets is 75mg to 150mg each day. After the early stages of treatment, it is usually possible to reduce the dose to 75mg to 100mg each day.

To treat menstrual cramps (period pain)

The tablets are usually taken during each period as soon as cramps begin and continued for a few days until the pain goes away.
The usual starting dose of Voltaren tablets is 50mg to 100mg each day, beginning as soon as cramps begin and continuing until the pain goes away, but for no longer than 3 days.
If necessary, the dose can be raised over several menstrual periods to a maximum of 200mg each day.

To treat post-operative pain in children

Your doctor will advise what strength and dose of Voltaren suppositories is suitable for your child.

How to take the tablets

Voltaren tablets are usually taken in 2 or 3 doses during the day.
Swallow the tablets whole with a full glass of water or other liquid. Do not chew them.
The tablets have a special coating to keep them from dissolving until they have passed through the stomach into the bowel. Chewing the tablets would destroy the coating.

How to use Voltaren suppositories

Do not take suppositories by mouth.
When used in children, the strength of the Voltaren suppository used depends on the weight of the child. Your doctor will decide which strength is suitable for your child and how often it can be used.
If possible, go to the toilet and empty your bowels before using the suppository.
Follow these steps:

1.Wash your hands thoroughly with soap and water.

2.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.

3.Put on a disposable glove, if desired (available from a pharmacy).

4.Remove the entire wrapper from the suppository.

5.Moisten the suppository by dipping it briefly in cool water.

6.Lie on your side and raise your knees to your chest.

7.Push the suppository, blunt end first, gently into your rectum (back passage). Do not break the suppository.

8.Remain lying down for a few minutes so that the suppository dissolves.

9.Wash your hands again thoroughly.

Try not to go to the toilet to empty your bowels for at least one hour after using the suppository.
If you are not sure how to use a suppository, ask your pharmacist or doctor.

How long to take/use it

Do not use Voltaren for longer than your doctor says.
If you are using 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.
Voltaren suppositories should not be used for more than 3 days in children.

If you forget to take/use it

If it is almost time for your next dose (e.g. 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.
This may increase the chance of you getting an unwanted side effect.
If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.

If you take/use too much Voltaren (Overdose)

Immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26), or go to Accident and Emergency at your nearest hospital if you think that you or anyone else may have used too much Voltaren. Do this even if there are no signs of discomfort or poisoning. Keep the telephone numbers for these places handy.
If you take too much Voltaren, you may experience:
bleeding from the stomach or bowel
ringing in the ears
convulsions (fits)
