There are a number of different brands of mesalamine, some of which work in different ways. This means that your treatment could be affected by switching between some brands. Each time you collect a new supply from your pharmacy, check to see if it is the same brand as before. If it is different, discuss this with your pharmacist who will advise you.
It is important that you keep your regular appointments with your physician so that your progress can be checked. You may require regular blood tests.
Common side-effects include gastrointestinal symptoms and aches and pains. These tend to be minor.
Rarely, mesalamine can cause problems with your blood. You should tell your physician immediately if you have any unexplained bleeding, bruising, red or purple discolorations of the skin, sore throat or a high temperature (fever), or if you feel generally unwell.

About mesalamine
Type de médicament | Un aminosalicylate |
Utilisé pour | Ulcerative colitis and Crohn's ileo-colitis, proctitis |
Également appelé | Asacol®; Apriso®; Canasa®; Delzicol®; Lialda®; Pentasa®; Rowasa® |
Disponible en | Capsules, tablets, suppositories, enemas |
Ulcerative colitis causes inflammation of the intestine, which leads to problems such as ulceration and bleeding. This causes symptoms such as abdominal pain and diarrhea. Crohn's disease is a condition which causes inflammation of any part of the gastrointestinal system. When the inflammation is in the area where the small intestine joins the large intestine then it is called Crohn's ileo-colitis. Aminosalicylates are a group of medicines commonly used to treat inflammatory bowel diseases such as these.
Mesalamine is one of the most commonly used aminosalicylates. Although it is not clear exactly how mesalamine works, it is thought to act on cells lining the intestine to change the way these cells make and release certain chemicals. These chemicals are thought to be a factor in causing the symptoms of ulcerative colitis. Mesalamine allows the damaged intestine to recover and helps to prevent symptoms from flaring up again.
There are a number of different mesalamine preparations, strengths and brands. The way the manufacturers make each of these brands differs slightly; this allows the different brands to release mesalamine in specific areas of the intestine. You will be prescribed the brand that allows mesalamine to be released in the part of your intestine which requires it most.
Mesalamine can be taken by mouth as capsules or tablets, or it can be given into the back passage (rectum) as a suppository or enema.
Before taking mesalamine
Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking mesalamine it is important that your physician knows:
If you are pregnant or breastfeeding. (Although mesalamine is unlikely to be harmful to babies, it is still important that you tell your physician if you are expecting or breastfeeding a baby.)
Si vous avez des problèmes de fonctionnement du foie ou des reins.
If you have ever had kidney stones (renal calculi) before.
Si vous avez des problèmes respiratoires.
If you have ever had an allergic reaction to a medicine. It is particularly important that you tell your physician if you have had an unusual reaction to aspirin or a salicylate.
Si vous prenez ou utilisez d'autres médicaments. Cela comprend tous les médicaments que vous prenez et qui sont disponibles sans ordonnance, ainsi que les médicaments à base de plantes et les médicaments complémentaires.

How to take/use mesalamine
Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about mesalamine, and it will also provide you with a full list of the side-effects which you could experience.
Your dose will depend upon which brand of mesalamine has been prescribed for you. Your physician will tell you how much to take and when to take it, and these directions will also be printed on the label of the pack to remind you about what the physician said to you. Take mesalamine exactly as your physician tells you to.
Some mesalamine tablets are specially coated to pass through your stomach before they are absorbed. These must be swallowed whole and not broken, chewed or crushed. Check the label on your pack carefully and follow any advice it gives. Also, do not take any indigestion remedies within two hours of taking your doses (either before or after), as this will interfere with the special coating.
Some mesalamine capsules can be opened and the contents sprinkled on to soft food such as applesauce or yogurt. Pour the contents on to a spoonful of food and swallow without chewing the granules. Check the label on your pack carefully and follow any advice it gives.
If you forget to take a dose, take it as soon as you remember, unless it is nearly time for your next dose, in which case leave out the missed dose and take the next dose as normal. Do not take two doses together to make up for a forgotten dose.
How to use mesalamine enema
Mesalamine works best when your bowel is empty.
The enema should be inserted at bedtime so it can work overnight.
Shake the enema and release the seal on the nozzle.
Lie down on one side and draw your top knee up towards your chest. Insert the enema nozzle into your back passage (rectum).
Squeeze the bottle gently to completely empty the contents. This will take around 30-40 seconds.
Remove the nozzle from your back passage whilst still squeezing the bottle. Remain where you are for about 5-10 minutes until the urge to pass the enema has eased.
Throw away the empty enema bottle in a plastic bag (these are provided with some brands of enema).
Lavez-vous les mains.
How to use mesalamine suppositories
Mesalamine works best when your bowel is empty.
The suppository should be inserted at bedtime so it can work overnight.
Retirer le suppositoire de son emballage.
En utilisant votre doigt, poussez doucement le suppositoire dans le passage arrière (rectum). Certaines personnes trouvent qu'il est plus facile de s'accroupir ou de s'allonger sur le côté et de ramener leurs genoux vers leur poitrine.
Push the suppository in as far as possible. You may have the urge to pass the suppository out again but this should ease after a few minutes.
Lavez-vous les mains.

Your physician may advise you make some changes to your diet as part of your treatment. This can include a special diet or a nutritional supplement.
