Uromitexan – Mesna uses, dose and side effects


(with preservative) 100 mg/ml solution for injection

What Uromitexan is and what it is used for

Uromitexan solution for injection is only given by healthcare professionals, who can answer any additional questions you may have after reading the information below.

Uromitexan is used to prevent mucosal damage in the bladder during treatment with ifosfamide or cyclophosphamide. Some cytostatics (ifosfamide, cyclophosphamide) can damage the lining of the bladder so that there is blood in the urine. If Uromitexan is given at the same time, it has a protective effect and the risk of inflammation in the bladder and blood in the urine is reduced.

What you need to know before receiving Uromitexan

Do not use Uromitexan

  • if you are allergic to mesna, other similar medicines ( thiols ), or any of the other ingredients, including benzyl alcohol in this medicine (listed in section 6).

Warnings and precautions

Talk to your doctor, pharmacist, or nurse before using Uromitexan:

  • if you have previously experienced breathing difficulties, wheezing, skin redness, itching, or swelling after receiving Uromitexan.
  • if you have any autoimmune disease, e.g. rheumatoid arthritis, systemic lupus erythematosus ( SLE ), or kidney inflammation, as these diseases can increase the risk of certain side effects.
  • if you have previously had a blockage or obstruction in the urinary tract, preventing normal urine output. Morning urine should be examined each day before treatment for microscopic blood findings ( hematuria ).

Urine test strips for ketone bodies or red blood cells ( erythrocytes ) can give incorrect results during medication with Uromitexan. Contact a doctor or nurse if you are unsure.

Stop using Uromitexan and contact your doctor immediately if you experience any of the following symptoms ( angioedema ):

  • swelling of the face, tongue, or throat
  • difficulty swallowing
  • hives and difficulty breathing.

Driving ability and use of machinery

Some side effects such as fainting, dizziness, drowsiness, and blurred vision can affect the ability to drive and use machines.

You are responsible for assessing whether you are fit to drive a motor vehicle or perform work that requires increased attention. One of the factors that can affect your ability in these respects is the use of drugs due to their effects and/or side effects. A description of these effects and side effects can be found in other sections. Read all the information in this leaflet for guidance. Discuss with a doctor or pharmacist if you are unsure.

Uromitexan contains sodium and benzyl alcohol

Uromitexan contains sodium

This medicine contains approximately 59 mg sodium per 400 mg mesna. This is equivalent to 2.95% of the maximum recommended daily intake of sodium for adults.

Uromitexan contains benzyl alcohol

Uromitexan (with preservative ) contains 10.4 mg of benzyl alcohol per ml. Benzyl alcohol can cause allergic reactions. Benzyl alcohol is associated with the risk of serious side effects such as breathing difficulties in young children.

The medicine should not be used by newborns (up to 4 weeks of age) unless a doctor has prescribed it. Do not use the medicine for more than 1 week in newborns (younger than 3 years) unless a doctor has recommended it.

If you have impaired liver or kidney function, or are pregnant or breastfeeding, consult a doctor or pharmacist before using this medicine. Large amounts of benzyl alcohol can be stored in the body and cause side effects (metabolic acidosis ).

How to receive Uromitexan

The dose is determined by the doctor, who adjusts it individually for you depending on your treatment with cytostatics (ifosfamide or cyclophosphamide).

Uromitexan solution for injection is given as an injection or as a drip ( infusion ) and is only given by healthcare professionals, who can provide more detailed information.

If you have been given too much Uromitexan

If you have ingested too much medicine or if, for example, a child has ingested the medicine by mistake, contact a doctor or hospital for an assessment of the risk and advice.

As the Uromitexan solution for injection is always given by healthcare professionals, you should first talk to them if you suspect that you have received too much of a dose.

Symptoms of overdose can be nausea, vomiting, stomach ache, diarrhea, headache, fatigue, pain in arms and legs, and joints, skin rash, hot flushes, low blood pressure, slow pulse, fast pulse, numbness, fever, and spasm in the muscles of the trachea.

If you have any further questions about this medicine, ask your doctor, pharmacist, or nurse.

Possible side effects

Like all medicines, this medicine can cause side effects, although not everybody gets them.

However, since Uromitexan is always taken at the same time as ifosfamide or cyclophosphamide, it is difficult to determine which of these preparations caused a side effect.
