Talk to your doctor or pharmacist before taking Diclofenac sodium Dexcel:
Tell your doctor if you recently had or you are going to have a surgery of the stomach or intestinal tract before taking Diclofenac sodium Dexcel, as diclofenac sodium can sometimes worsen wound healing in your gut after surgery.

Some medicines can interfere with your treatment. Please tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.
Very occasionally people have reported that diclofenac sodium tablets have made them feel dizzy, tired or sleepy. Problems with eyesight have also been reported. If you are affected in this way, you should not drive or operate machinery.
If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.
This medicine contains less than 1 mmol sodium (23 mg) per tablet, that is to say essentially 'sodium-free'.
The doctor will tell you how many Diclofenac sodium Dexcel tablets to take and when to take them. Always take this medicine exactly as your doctor or pharmacist has told you. Check with your doctor or pharmacist if you are not sure.
Take the tables with or after food.
Swallow the tablets whole with a glass of water. Do not crush or chew the tablets as this will affect the special “slow release” system.
The recommended dose is:
Adults: 100-150mg daily divided into two or three doses. The number of tablets which you take will depend on the strength the doctor has given you.
Your doctor may wish to increase your daily dose if required to 150mg.
Elderly: The lowest effective dose should be used. Your doctor may advise you to take a dose that is lower than the usual adult dose if you are elderly. Close surveillance is advisable.
Children: These tablets are not suitable for children.
The doctor may also prescribe another drug to protect the stomach to be taken at the same time, particularly if you have had stomach problems before, or if you are elderly, or taking certain other drugs as well.
If you, or anyone else, accidentally takes too much Diclofenac sodium Dexcel, tell your doctor or go to your nearest hospital casualty department immediately. Take your medicine pack with you so that people can see what you have taken.
Symptoms of an overdose can include: headache, nausea (feeling sick), vomiting, abdominal pain, stomach or intestinal bleeding, rarely diarrhoea, disorientation, excitation, coma, drowsiness, dizziness, ringing in the ears, fainting, or occasionally convulsions (seizures, uncontrolled fits).
It is important that you do not miss a dose. If you forget to take a dose, take one as soon as you remember. If it is nearly time for your next dose, just take the next dose and forget about the one you missed. Do not take a double dose to make up for a forgotten tablet. Do not take more than 150 mg in 24 hours. If you have trouble remembering to take the tablets, tell your doctor or pharmacist.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
