2026/07/07
What is this medication for?
Diclofenac is a non-steroidal anti-inflammatory drug (NSAID) that is commonly used to relieve pain and reduce inflammation (redness, swelling and soreness).
How should I take/use this medication?

Suppositories are for rectal use only. Administer as directed by your doctor:

How to use suppositories:

  1. Wash and dry your hands.
  2. Tear off one single suppository and remove the plastic wrapper. If the suppository is too soft, place it in the refrigerator for a few minutes until it is firm.
  3. You may moisten the rectal area with a small amount of water for easier insertion of the suppository.
  4. Lie down on your side with your top leg slightly bent toward your stomach and your bottom leg straight.
  5. Insert the suppository into the rectum, narrow end first. Gently but firmly push the suppository into the rectum.
  6. Remain lying for 5 to 10 minutes to allow the suppository to melt and release the medications.
  7. Wash your hands with soap and water after using a suppository.
What should I do if I forget to take or use this medication?
Diclofenac can be taken on as needed basis for short term use as prescribed by the doctor. 

If your doctor has prescribed the medication for you to be taken regularly, do not stop taking your medication without checking with your healthcare professional. If you miss a dose, take the missed dose as soon as you remember. If it is almost time for your next dose, take only the usual dose. Do not double your dose or use extra medication to make up for the missed dose.
