MEZAVANT 1200 mg PROLONGED-RELEASE GASTRO-RESISTANT TABLETS

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 forget to take the tablets, take them as usual the next day. Do not take a double dose to make up for the forgotten dose.

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

• If you observe reddish, non-elevated spots, with a target-like or circular appearance on the trunk, often with central blisters, skin peeling, mouth ulcers, genital ulcers, and eye ulcers, generalized rash, fever, and swollen lymph nodes. These severe skin rashes can be preceded by fever and flu-like symptoms.
• If you suffer from allergic swelling of the tongue, lips, and around the eyes.
• If you experience severe or recurrent headache, vision changes, or ringing or buzzing in the ears. These could be symptoms of increased pressure inside your skull (idiopathic intracranial hypertension).

The following side effects have been reported, but it is not known how often they occur:

Severe decrease in blood cells, which can cause weakness or bruising; low blood cell counts; allergic reaction (hypersensitivity); severe allergic reaction that causes difficulty breathing or dizziness; severe skin disease with blistering of the skin (which can cause skin peeling and painful raw areas), mouth, eyes, and genitals; allergic reaction that causes skin rash, fever, and inflammation of internal organs; neuropathy (abnormalities or damage to the nerves that cause numbness and tingling); heart inflammation and inflammation of the heart lining; lung inflammation; breathing difficulties or wheezing; gallstones; hepatitis (inflammation of the liver that causes flu-like symptoms and jaundice); liver damage (which can present as abnormal liver tests); allergic swelling of the tongue, lips, and around the eyes; skin redness; skin rash, usually on the face, sensitivity of the skin to sunlight, along with joint pain, arthritis, fatigue, and general feeling of being unwell; kidney problems (such as inflammation and scarring of the kidneys); kidney stones and the associated pain (see also section 2); reversible decrease in sperm production.
