NEW Asamax® 500 is a FULLY FUNDED medication for the treatment of Crohn’s disease and ulcerative colitis.

What is Asamax? 
Asamax (mesalazine) tablets are used to treat ulcerative colitis and Crohn’s disease which cause inflammation of the bowel, bleeding from the rectum, stomach pain and diarrhoea.

The active ingredient in this medicine is mesalazine. It is an anti-inflammatory agent and is thought to suppress the inflammation in the bowel. This medication helps to control your condition, but does not cure it.

Asamax is a prescription only medicine. 

How should I take Asamax? 
Take this medication exactly as it was prescribed for you. Dosing depends on the disease you are suffering from. Do not take the medication in larger amounts, and continue using your medicine for as long as your doctor tells you, even if you feel well.

It is very IMPORTANT that you follow the directions on your prescription label. 

Asamax tablets must be taken whole and must not be divided. 
Asamax tablets should be taken after meals with a little water and must not be chewed. 

Who can take Asamax? 
Asamax can be used in adults and children over the age of two. 

Can I take Asamax if I am pregnant or breast feeding? 
Your doctor can discuss with you the risks and benefits involved. Asamax should be used with caution during pregnancy and lactation (breast feeding).

What are the side effects of Asamax? 
Asamax helps most people but a few people do experience side effects. All medicines can have side effects. Not all of these side effects may occur, and if they do occur you may need medical attention.

The most common side effects are nausea, diarrhoea, abdominal pain / cramps, headache, dizziness and mood swings.

Stop taking this medicine and check with your doctor or pharmacist immediately if you experience any of these side effects.

How do I start on Asamax? 
Asamax is FULLY FUNDED without restriction and therefore you do not need to pay for this medicine. You will need to make an appointment to see your local doctor and discuss whether Asamax is right for you. Doctor fees and a pharmacist charge may apply.
