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

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

How much to take

The usual starting dose is 75mg to 150mg per day. For long-term treatment, 75mg to 100mg daily is usually sufficient.

In period pain, the usual starting dose is 50mg to 100mg per 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 increased over several menstrual cycles up to a maximum of 200mg per day.

Do not exceed the recommended dose.

Ask your doctor or pharmacist if you are unsure of the correct dose for you. They will tell you exactly how much to take.

Follow the instructions they give you. If you take the wrong dose, Diclofenac Sandoz may not work as well and your problem may not improve.

How to take it

Diclofenac Sandoz 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. These tablets have a special coating to stop them dissolving until they have gone through the stomach and into the intestines, where they can start to work. If you chew them, the coating is destroyed.

When to take Diclofenac Sandoz

It is recommended to take the tablets before meals. You may take them with, or immediately after food in order to reduce the chance of stomach upset.

How long to take Diclofenac Sandoz

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

This medicine helps to control your condition but does not cure it.

If you forget to take it

Take your dose as soon as you remember, and continue to take it as you would normally.

If it is almost time for your next dose, skip the dose you missed and take your next dose when you are meant to.

Do not take a double dose to make up for the dose that you missed. This may increase the chance of you getting an unwanted side effect.

If you are not sure what to do, ask your doctor or pharmacist.

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

If you take too much (overdose)

Immediately telephone your doctor or the Poisons Information Centre (telephone 13 11 26 or New Zealand 0800 POISON or 0800 764766) for advice, or go to Accident and Emergency at the nearest hospital, if you think you or anyone else may have taken too much Diclofenac Sandoz. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

Symptoms of an overdose may include:

  • vomiting
  • bleeding from the stomach or bowel
  • diarrhoea
  • dizziness
  • ringing in the ears
  • convulsions (fits).


Things you must do

If you become pregnant while taking this medicine, tell your doctor immediately. Your doctor can discuss with you the risk of using it while you are pregnant.

Tell your doctor if you get an infection while taking this medicine. 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.

Keep all of your doctor's appointments so that your progress can be checked. Your doctor will periodically re-evaluate whether you should continue treatment, if you have established heart disease or significant risks for heart disease, especially in case you are treated for more than 4 weeks.

Your doctor may do some tests (check your kidneys, liver and blood) from time to time to prevent unwanted side effects.

If, at any time while taking CLONAC you experience any signs or symptoms of problems with your heart or blood vessels such as chest pain, shortness of breath, weakness, or slurring of speech, contact your doctor immediately.

  • ibuprofen
  • any other NSAID medicine.

If you take these medicines together with Diclofenac Sandoz, they may cause unwanted side effects.

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

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 take Diclofenac Sandoz to treat any other complaints unless your doctor tells you to.

Do not give your medicine to anyone else, even if they have the same condition as you.
