Further precautions During treatment your doctor may want to keep you under close medical supervision and you may need to have regular blood and urine tests. In patients who have undergone certain types of bowel surgery, Salofalk 1g tablets may be excreted undissolved in the stool. If you notice this, please inform your doctor. Kidney stones may develop with use of mesalazine. Symptoms may include pain in sides of abdomen and blood in urine. Take care to drink sufficient amount of liquid during treatment with mesalazine. Serious skin reactions including drug reaction with eosinophilia and systemic symptoms (DRESS), Stevens-Johnson syndrome (SJS), and toxic epidermal necrolysis (TEN) have been reported in association with mesalazine treatment. Stop using mesalazine and seek medical attention immediately if you notice any of the symptoms related to these serious skin reactions described in section 4. If you experience strong or recurrent headache, disturbed vision, or ringing or buzzing in the ears contact your doctor immediately.

For the treatment of acute episodes of mild to moderate ulcerative colitis.
Posology
Adults
The recommended daily dose for the treatment of acute episodes of mild to moderate ulcerative colitis is one Salofalk 1g tablet three times a day (morning, midday and evening, equivalent to 3 g of mesalazine daily).
Paediatric population
There is only limited documentation for an effect in children (age 6-18 years).
Children 6 years of age and older and of a body weight > 40 kg
The dose should be determined individually, starting with 30-50 mg/kg/day in divided doses. Maximum dose: 75 mg/kg/day. The total dose should not exceed the maximum adult dose.
Children above a body weight of 40 kg could be treated with the same dose as adults.
Children 6 years of age and older and of a body weight ≤ 40 kg
In children up to 40 kg, it appears preferable to use mesalazine preparations of lower strengths (e.g., products containing 500 mg mesalazine).
Method of administration
Salofalk 1g tablets should be taken 1 hour before meals. They should be swallowed whole, not chewed to ensure the integrity of the gastro-resistant coating, and taken with plenty of fluid.
In case of difficulties swallowing the tablet, another mesalazine formulation (e.g. granules) should be used.
Therapy with Salofalk 1g tablets should be administered regularly and consistently in order to achieve the desired therapeutic effect.
Duration of treatment
The duration of use is determined by the physician. Induction of remission is usually achieved within 8 weeks.
Note:
The standard treatment of the maintenance of remission is 500 mg mesalazine three times daily. For this indication products containing 500 mg mesalazine are available.
Salofalk 1g tablets are contraindicated in patients with:
- Hypersensitivity to the active substance, salicylates or to any of the excipients listed in section 6.1
- Severe impairment of hepatic or renal function.
Blood tests (differential blood count; liver function parameters such as ALT or AST; serum creatinine) and urinary status (dip sticks) should be determined prior to and during treatment, at the discretion of the treating physician. As a guideline, follow-up tests are recommended 14 days after commencement of treatment, then a further two to three tests at intervals of 4 weeks.
If the findings are normal, follow-up tests should be carried out every 3 months. If additional symptoms occur, these tests should be performed immediately.
Caution is recommended in patients with impaired hepatic function.
Mesalazine should not be used in patients with impaired renal function. Mesalazine-induced renal toxicity should be considered, if renal function deteriorates during treatment. If this is the case, Salofalk 1g tablets should be discontinued immediately.
Cases of nephrolithiasis have been reported with the use of mesalazine including stones with a 100% mesalazine content. It is recommended to ensure adequate fluid intake during treatment.
Mesalazine may produce red-brown urine discoloration after contact with sodium hypochlorite bleach (e.g., in toilets cleaned with sodium hypochlorite contained in certain bleaches).
Serious blood dyscrasias have been reported very rarely with mesalazine. Hematological investigations should be performed if patients suffer from unexplained haemorrhages, bruises, purpura, anaemia, fever or pharyngolaryngeal pain. Salofalk 1g tablets should be discontinued in case of suspected or confirmed blood dyscrasia.
Cardiac hypersensitivity reactions (myocarditis, and pericarditis) induced by mesalazine have been rarely reported. Salofalk 1g tablets should then be discontinued immediately.
Patients with pulmonary disease, in particular asthma, should be very carefully monitored during a course of treatment with mesalazine.
Severe cutaneous adverse reactions
Severe cutaneous adverse reactions (SCARs), including drug reaction with eosinophilia and systemic symptoms (DRESS), Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN), have been reported in association with mesalazine treatment.
Mesalazine should be discontinued, at the first appearance of signs and symptoms of severe skin reactions, such as skin rash, mucosal lesions, or any other sign of hypersensitivity.
Idiopathic intracranial hypertension
Idiopathic intracranial hypertension (pseudotumor cerebri) has been reported in patients receiving mesalazine. Patients should be warned for signs and symptoms of idiopathic intracranial hypertension, including severe or recurrent headache, visual disturbances or tinnitus. If idiopathic intracranial hypertension occurs, discontinuation of mesalazine should be considered.
Patients with a history of adverse drug reactions to preparations containing sulphasalazine should be kept under close medical surveillance on commencement of a course of treatment with mesalazine.
Should Salofalk 1g tablets cause acute intolerance reactions such as abdominal cramps, acute abdominal pain, fever, severe headache and rash, therapy should be discontinued immediately.
Note:
In patients who have undergone bowel resection/bowel surgery in the ileocoecal region with removal of the ileocoecal valve, it may happen that Salofalk 1g tablets are excreted undissolved in the stool, due to an excessively rapid intestinal passage.
This medicine contains less than 1 mmol sodium (23 mg) per tablet, that is to say essentially 'sodium-free'.
Specific interaction studies have not been performed.
In patients who are concomitantly treated with azathioprine, 6‑mercaptopurine or thioguanine, a possible increase in the myelosuppressive effects of azathioprine, 6‑mercaptopurine or thioguanine should be taken into account.
There is weak evidence that mesalazine might decrease the anticoagulant effect of warfarin.
Pregnancy
There are no adequate data on the use of mesalazine in pregnant women. However, data on a limited number of exposed pregnancies indicate no adverse effect of mesalazine on pregnancy or on the health of the fetus/newborn child. To date no other relevant epidemiologic data are available. In one single case after long-term use of a high dose mesalazine (2‑4 g, orally) during pregnancy, renal failure in a neonate was reported.
Animal studies on oral mesalazine do not indicate direct or indirect harmful effects with respect to pregnancy, embryonic/fetal development, parturition or postnatal development.
Salofalk 1g tablets should only be used during pregnancy if the potential benefit outweighs the possible risk.
Breast-feeding
N-acetyl-5-aminosalicylic acid and to a lesser degree mesalazine are excreted in breast milk. Only limited experience during lactation in women is available to date. Hypersensitivity reactions such as diarrhoea in the infant cannot be excluded. Therefore, Salofalk 1g tablets should only be used during breast-feeding if the potential benefit outweighs the possible risk. If the infant develops diarrhoea, the breast-feeding should be discontinued.
Mesalazine has no or negligible influence on the ability to drive and use machines.
