Mesnex: Uses, Dosage, Demographic, Side Effects, Interactions, and Generic Options Mesnex (mesna) is a chemotherapy drug that is used to prevent or reduce inflammation and damage to the bladder caused by certain chemotherapy drugs, such as ifosfamide and cyclophosphamide. Mesnex is also used for preventing hemorrhagic cystitis (bleeding in the bladder). Uses Mesnex is mainly used to reduce the occurrence and severity of hemorrhagic cystitis (bleeding in the bladder) in patients receiving high dose chemotherapy with cyclophosphamide and ifosfamide. This medication works by binding to ifosfamide metabolites in the urinary tract, which reduces bladder irritation and bleeding from cyclophosphamide and its metabolites. Without mesna, these chemotherapy drugs can cause inflammation and bleeding in the bladder, leading to potentially serious or fatal complications. Furthermore, mesna is also recommended for people who have been exposed to acrolein, a toxic byproduct of cyclophosphamide and ifosfamide that can damage the kidneys, lungs, and gastrointestinal tract. Additionally, mesna can be used for other purposes not listed in this medication guide. Dosage Mesnex is available in a liquid and tablet form. The dosage of Mesnex is based on the individual's body weight, the chemotherapy drug used, dose, and regiment. The dosage of Mesnex should be prescribed by a qualified healthcare provider to determine the correct dose based on the individual's condition. The usual starting dose of Mesnex is 20% of the ifosfamide or cyclophosphamide dose given every four hours during the chemotherapy treatment period. Demographic Mesnex is indicated for preventing hemorrhagic cystitis in patients receiving high-dose ifosfamide and cyclophosphamide chemotherapy. Patients with cancer who undergo chemotherapy with these medications are at risk of developing hemorrhagic cystitis, particularly if they receive high doses or several courses of chemotherapy over time. Hemorrhagic cystitis is seen more frequently in young children and the elderly.
