1) What Pentasa is and what it is used for
The name of this medicine is Pentasa 1g Suppositories. Each suppository
contains mesalazine 1g as the active ingredient. Mesalazine belongs to a
group of medicines called salicylates.

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.

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.
