What Voltaren Rapid is used for

Voltaren Rapid belongs to a group of medicines called non-steroidal anti-inflammatory drugs (NSAID). It relieves pain and reduces inflammation (swelling and redness).
It is used for short-term treatment of the following conditions:
migraine headaches and it may also relieve the accompanying symptoms, such as nausea and vomiting, which you sometimes experience when you have a migraine
relief of menstrual cramps (period pain).
short-term treatment (up to 1 week) of other painful conditions where swelling is a problem such as back or joint pain, dental pain, muscle strains or sprains and tendonitis (e.g. tennis elbow).
Voltaren Rapid 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 Rapid is only available with a doctor's prescription. It is not addictive.
There is not enough information to recommend this medicine for children and adolescents under 14 years of age.

Before you take Voltaren Rapid

When you must not take it

Do not take Voltaren Rapid if you are allergic (hypersensitive) to:
diclofenac (the active ingredient in Voltaren Rapid) or any of the other ingredients listed at the end of this leaflet
other medicines containing diclofenac (e.g. Voltaren tablets or suppositories, Voltaren Emulgel, Voltfast powder)
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 take Voltaren Rapid, these symptoms may be severe.
Do not take Voltaren Rapid 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 take Voltaren Rapid 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 take Voltaren Rapid 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 take 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.
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)
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 Rapid during the first 6 months of pregnancy and it must not be used during the last 3 months.
Voltaren Rapid 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 take Voltaren Rapid 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 Rapid passes into breast milk and may affect your baby.
Tell your doctor if you are fructose intolerant.
This medicine contains sucrose, which is converted by the liver to fructose.
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

How to take Voltaren Rapid

Swallow the Voltaren Rapid tablets whole with a full glass of water. Do not break them or chew them.

When to take it

Take the tablets preferably before meals. 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.

How much Voltaren Rapid to take

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 Rapid depending on your condition. Your doctor will tell you exactly how many tablets to take.
Do not exceed the recommended dose.

To treat migraine

The usual dose is 50 mg (one tablet) at the first sign of an attack. If the pain is not relieved within 2 hours, another tablet can be taken. After that, you must wait at least 4 hours before taking any more Voltaren Rapid.
Do not take more than 200 mg (4 tablets) in 24 hours even if you have more than one migraine attack within that 24 hour period.

To treat menstrual cramps (period pain)

The usual dose is 50 mg to 100 mg (1 to 2 tablets) beginning as soon as cramps begin. This is usually followed by 1 tablet three times each day until the pain goes away, but for no longer than 3 days.

To treat other painful conditions

The usual dose is 100 mg to 150 mg (2 to 3 tablets) each day. In milder cases, as well as in children over 14 years old, 75 mg to 100 mg each day is usually enough.

How long to take it

Do not take Voltaren Rapid for longer than your doctor says.
It is usually taken for a short time only (up to one week) but it may be prescribed on repeated occasions, depending on your condition.

If you forget to take 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 too much (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 taken too much Voltaren Rapid. 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 Rapid, you may experience:
bleeding from the stomach or bowel
ringing in the ears
convulsions (fits)
