1. What is Mezavant and what is it used for
Pharmacotherapeutic group: aminosalicylic acid and similar agents.
Mezavant, gastro-resistant prolonged-release tablets, contains the active substance mesalazine, which is an anti-inflammatory drug for the treatment of ulcerative colitis.
Ulcerative colitis is a disease of the colon (large intestine) and rectum (the last part of the large intestine), in which the lining of the intestine becomes red and swollen (inflamed), causing symptoms such as frequent bowel movements with blood along with stomach discomfort.
When administered for an acute episode of ulcerative colitis, Mezavant acts throughout the colon and rectum, treating inflammation and reducing symptoms. The tablets can also be taken to prevent the recurrence of ulcerative colitis.
2. What you need to know before you take Mezavant
Do not take Mezavant
- If you are allergic (hypersensitive) to a class of drugs known as salicylates (which includes acetylsalicylic acid [Aspirin]).
- If you are allergic (hypersensitive) to mesalazine or any of the other components of this medicine (listed in section 6).
- If you have severe kidney or liver problems.
Warnings and precautions
Mesalazine may produce a discoloration of the urine to a reddish-brown color after contact with sodium hypochlorite bleach in the toilet water. This is a chemical reaction between mesalazine and the bleach and is harmless.
Consult your doctor before starting to take Mezavant
- If you have any kidney or liver problems.
- If you have had heart inflammation previously (which could be a consequence of a heart infection).
- If you have ever developed a severe skin rash or peeling of the skin, blisters, and/or sores in the mouth after using Mezavant.
- If you have had a previous allergy to sulfasalazine (another medicine used to treat ulcerative colitis).
- If you have narrowing or obstruction of the stomach or intestine.
- If you have lung problems.
Before and periodically during treatment with Mezavant, your doctor may take urine and blood samples to check that your kidneys and liver are working properly and that your blood is healthy.
Kidney stones can form with the use of Mezavant. The symptoms may include pain in the sides of the abdomen and blood in the urine. Be careful to drink a sufficient amount of liquid during treatment with Mezavant.
Severe skin reactions, such as drug reaction with eosinophilia and systemic symptoms (DRESS), Stevens-Johnson syndrome (SSJ), and toxic epidermal necrolysis (NET), have been reported in association with Mezavant treatment. If you observe any of the symptoms related to these severe skin reactions described in section 4, discontinue Mezavant administration and seek immediate medical attention.
Consult your doctor:
If you experience severe or recurrent headache, vision changes, or ringing or buzzing in the ears, contact your doctor immediately
Children and adolescents
Mezavant is not recommended for children and adolescents who weigh 50 kg or less or for children under 10 years of age due to the lack of data on safety and efficacy (see section 3).
Other medicines and Mezavant
Studies have shown that Mezavant does not interfere with the following antibiotics used to treat infections: amoxicillin, metronidazole, or sulfamethoxazole.
However, Mezavant may interact with other medicines. Inform your doctor or pharmacist if you are taking, have recently taken, or might take any other medicine that contains:
- Mesalazine or sulfasalazine (taken for the treatment of ulcerative colitis).
- Non-steroidal anti-inflammatory drugs (e.g., medicines containing acetylsalicylic acid [Aspirin], ibuprofen, or diclofenac).
- Azathioprine, 6-mercaptopurine, or other medicines that are known to affect the functioning of the bone marrow (known as immunosuppressant medicines that reduce the activity of the immune system). The bone marrow is the tissue inside the bones that produces blood cells.
- Coumarin anticoagulants (medicines that prolong the time it takes for blood to clot), such as warfarin.
Taking Mezavant with food and drinks
Mezavant should be taken with food at the same time every day. The tablets should be swallowed whole and not crushed or chewed.
Pregnancy and breastfeeding
Since mesalazine crosses the placenta during pregnancy and is excreted in breast milk in small amounts, you should only take Mezavant during pregnancy or breastfeeding if your doctor advises you to. Adverse outcomes (including low blood cell counts in newborns) have been reported in infants born to mothers who took Mezavant during pregnancy. Diarrhea has been reported in infants of mothers who took Mezavant.
If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor before taking Mezavant.
Interference with laboratory tests
If you are having urine tests, it is important that you inform your doctor or nurse that you are taking or have recently taken this medicine, as it may affect some test results.
Driving and using machines
It is unlikely that Mezavant will have any effect on your ability to drive or use machines.
Mezavant contains sodium
This medicine contains less than 23 mg of sodium (1 mmol) per maximum recommended dose (4 tablets); this is essentially "sodium-free".
3. How to take Mezavant
Follow the instructions for administration of this medicine exactly as indicated by your doctor. If you are unsure, consult your doctor or pharmacist again.
The recommended dose for adults is 2.4 g to 4.8 g (two to four tablets) administered once daily 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 symptoms have subsided and to prevent recurrence of episodes, your doctor should advise you to take 2.4 g (two tablets) once daily.
For an acute episode of ulcerative colitis (in the first 8 weeks of treatment) in children and adolescents who weigh more than 50 kg and are 10 years or older, the recommended dose is 2.4 g to 4.8 g (two to four tablets) administered once daily.
To prevent recurrence of another episode of ulcerative colitis in children and adolescents who weigh more than 50 kg and are 10 years or older, the recommended dose is 2.4 g (two tablets) administered once daily.
Do not forget to take the tablets at the same time every day, with food. The tablets should be swallowed whole and not crushed or chewed.
While taking this medicine, make sure to drink liquids to stay well-hydrated, especially after severe or prolonged episodes of vomiting or diarrhea, high fever, or excessive sweating.
Mezavant is not recommended for children and adolescents who weigh 50 kg or less or for children under 10 years of age due to the lack of data on safety and efficacy.
If you take more Mezavant than you should
If you take too much Mezavant, you may experience one or more of the following symptoms: ringing in the ears (tinnitus), dizziness, headache, confusion, drowsiness, shortness of breath, excessive water loss (associated with sweating, diarrhea, and vomiting), low blood sugar (which can cause dizziness), rapid breathing, changes in blood chemistry, and increased body temperature.
If you take too many tablets, contact your doctor, pharmacist, or hospital emergency department immediately. Bring the tablet packaging with you.
If you forget to take Mezavant
It is important that you take the Mezavant tablets every day, even when you have no symptoms of ulcerative colitis. Always finish the prescribed treatment cycle.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
