Warnings and precautions
Before starting mesalazine treatment, the patient should inform their doctor:
When to exercise special caution when using mesalazine:
Severe skin reactions, including drug reaction with eosinophilia and systemic symptoms (DRESS), Stevens-Johnson syndrome (SJS), toxic epidermal necrolysis (TEN), and other serious symptoms, have been reported with mesalazine treatment. The patient should stop using mesalazine and seek medical attention immediately if they experience any of these severe skin reactions, listed in section 4.
Before starting Asamax 250 and Asamax 500 treatment, the patient should discuss this with their doctor or pharmacist.
- Before starting treatment and during treatment, the doctor will recommend regular blood tests (morphology, liver and kidney function parameters). If serious blood count disorders occur, the doctor will discontinue treatment.
- The doctor will exercise caution in patients with liver function disorders.
- The medicine should not be used in patients with kidney function disorders. In patients who develop kidney failure during treatment, the possibility of mesalazine toxicity should be considered.
- The doctor will closely monitor patients with lung diseases, especially asthma.
- The doctor will closely monitor patients who have experienced side effects after using sulfasalazine-containing medicines and will discontinue treatment if they occur.
- If the patient experiences heart hypersensitivity reactions (myocarditis and pericarditis), the doctor will discontinue treatment.
- Mesalazine may cause kidney stones. Symptoms may include abdominal pain and hematuria. During mesalazine treatment, the patient should drink plenty of fluids.
- Mesalazine may cause a reddish-brown discoloration of urine after contact with sodium hypochlorite bleach in toilet water. This is a harmless chemical reaction between mesalazine and bleach.
Children and adolescents
Data on the use of mesalazine in children and adolescents are limited.
Asamax 250 and Asamax 500 and other medicines
The patient should tell their doctor about all medicines they are currently taking or have recently taken, as well as any medicines they plan to take.
In patients who are also taking azathioprine, 6-mercaptopurine, or thioguanine, there is a possibility of increased bone marrow suppressive effects of these medicines.
There is limited evidence that mesalazine may reduce the anticoagulant effect of warfarin (a medicine that reduces blood clotting).
Pregnancy, breastfeeding, and fertility
If the patient is pregnant or breastfeeding, thinks they may be pregnant, or plans to have a child, they should consult their doctor before using this medicine.
Asamax 250 and Asamax 500 should only be used during pregnancy if the potential benefits outweigh the expected risks.
There are insufficient data on the use of mesalazine in pregnant women. Data from a limited number of women exposed to mesalazine during pregnancy did not show a negative effect on pregnancy or the health of the fetus or newborn. Other epidemiological data are not available at present.
In a single case, after using high doses of mesalazine (2-4 g orally) during pregnancy, kidney failure was reported in a newborn.
Animal studies with oral mesalazine did not show a direct or indirect harmful effect on pregnancy, embryonic or fetal development, or newborn development.
Asamax 250 and Asamax 500 should only be used during breastfeeding if the potential benefits outweigh the expected risks.
N-acetyl-5-aminosalicylic acid and, to a lesser extent, mesalazine pass into breast milk in small amounts. To date, there are only limited data from breastfeeding women. In breastfed infants, hypersensitivity reactions such as diarrhea cannot be excluded. If diarrhea occurs in a breastfed infant, breastfeeding should be discontinued.
The use of mesalazine during pregnancy and breastfeeding is always decided by the doctor.
Reversible decreased sperm count in semen has been rarely reported with mesalazine use. There are no data on the effect of mesalazine on fertility in women.
Driving and using machines
No effect of mesalazine on the ability to drive and use machines has been observed.
3. How to use Asamax 250 and Asamax 500
These medicines should always be used according to the doctor's recommendations. In case of doubts, the patient should consult their doctor or pharmacist.

The desired therapeutic effect of mesalazine can only be achieved if the dosage recommendations are consistently and accurately followed.

The safety and efficacy of the medicine in children have not been established due to limited experience and data.
Duration of treatment
The duration of treatment is always determined by the doctor, depending on the severity of symptoms.
Method of administration
The suppository should be inserted into the rectum through the anus. It is easiest to insert the suppository into the rectum while lying on your side, with your legs slightly bent.
Using a higher dose of Asamax 250 or Asamax 500 than recommended
There are limited data on overdose (e.g., attempted suicide after taking the medicine), which do not indicate toxic effects of mesalazine on the liver and kidneys. There is no specific antidote, and treatment of overdose is symptomatic and supportive.
In case of using a higher dose of the medicine than recommended, the patient should contact their doctor immediately.
Missing a dose of Asamax 250 or Asamax 500
If the patient forgets to take the next dose, they should take it as soon as possible, unless the time to the next dose is less than 2-3 hours. In this case, they should only take the next dose. They should not take a double dose to make up for the missed dose.
In case of any further doubts about using this medicine, the patient should consult their doctor or pharmacist.
