Further Information

1. What Pentasa is and what it is used for
The name of this medicine is Pentasa Suppositories. Each
suppository contains mesalazine 1g as the active ingredient.
Mesalazine belongs to a group of medicines called salicylates.
Pentasa is used to treat inflammation in the gut caused by
conditions such as ulcerative colitis. Sometimes ulcerative
colitis only affects the back passage (rectum), this is known as
ulcerative proctitis. Pentasa suppositories are used to treat
ulcerative proctitis and are intended for rectal use only.
The suppositories release the active ingredient slowly which
then acts locally to reduce the inflammation and help relieve or
stop the pain.

3. How to use Pentasa
Always use Pentasa exactly as your doctor has told you. You
should check with your doctor or pharmacist if you are not sure.
The suppository should be inserted into the back passage
(rectum) only. It is intended to be left in place for as long as
possible and is therefore best inserted before going to sleep.
To treat an attack of proctitis your doctor will usually prescribe
one suppository to be used daily for two to four weeks.
To help prevent further attacks it may be used for longer.
How to insert the suppository
You should make sure that you empty your bowels before
inserting the suppository.
a. Tear along the perforation to remove one suppository
blister from a blister strip
b. Put a protector on the finger with which you will insert
the suppository
c. Remove the suppository from the blister before insertion.
This is done by pushing the suppository through the
printed foil
d. Insertion may be made easier if you moisten the
suppository with water first
e. Insert the suppository gently and fully into the back
passage. It may help to lie down on one side and raise
the other knee
f. Remain still for a few minutes after insertion to help keep
the suppository in place. If it comes out within 10
minutes, a new one should be inserted
g. Dispose of the empty blister and used finger protector
safely and wash your hands
