1. Why am I using MESALZ?
MESALZ contains the active ingredient mesalazine (also called 5-aminosalicylic acid or 5-ASA). MESALZ is an anti-inflammatory drug used for the treatment of ulcerative colitis. When MESALZ is taken for a flare up of ulcerative colitis, it acts through the entire colon and rectum to treat the inflammation and reduce symptoms. MESALZ can also be taken to help prevent re-occurrence of ulcerative colitis.
2. What should I know before I use MESALZ?

Some medicines may interfere with MESALZ and affect how it works.
These include:

- azathioprine or 6-mercaptopurine (known as ‘immunosuppressant’ medicines).

4. How do I use MESALZ?
How much to take
- Adults and the early:
The usual daily dose for adults and the elderly is 2.4 g to 4.8 g (two to four tablets) taken once a day for an acute episode of ulcerative colitis. If you are taking the highest daily dose of 4.8 g/day, you should be evaluated after 8 weeks of treatment. Once your symptoms have cleared and to help prevent re-occurrence of another episode, your doctor may direct you to take 2.4 g (two tablets) once a day.
Children and Adolescents:
MESALZ is not recommended to be given to children under 18 years of age due to lack of data on safety and efficacy.
- Follow the instructions provided and use MESALZ until your doctor tells you to stop.
When to take MESALZ
- Take MESALZ at the same time each day. It is important to take MESALZ every day for as long as your doctor tells you to, even when you don’t have any symptoms of ulcerative colitis.
How to take MESALZ
- MESALZ can be taken with or without food. The tablets must be swallowed whole and must not be crushed or chewed.
If you forget to use MESALZ
MESALZ should be used regularly at the same time each day. If you miss your dose at the usual time, then take them as usual the next day.
Do not take a double dose to make up for the dose you missed.
If you use too much MESALZ
If you think that you have used too much MESALZ, you may need urgent medical attention.
You should immediately:
- phone the Poisons Information Centre (by calling 13 11 26), or
- contact your doctor, or
- go to the Emergency Department at your nearest hospital.
You should do this even if there are no signs of discomfort or poisoning.
5. What should I know while using MESALZ?
Things you should do
- make sure that all of your doctors, dentists, and pharmacists know you are taking MESALZ. Remind them if any new medicines are about to be started.
- ensure adequate fluid intake during treatment.
Things you should not do

- do not give to children under 18 years of age. MESALZ is not suitable for children under 18 years of age as there is not enough information on its effects in children.
