Dosage Form: injection, solution
Medically reviewed on February 1, 2018
Indications and Usage for Mesna
Mesna Injection is indicated as a prophylactic agent in reducing the incidence of ifosfamide-induced hemorrhagic cystitis.
Limitation of Use:
Mesna Injection is not indicated to reduce the risk of hematuria due to other pathological conditions such as thrombocytopenia.
Mesna Dosage and Administration
Mesna injection may be given on a fractionated dosing schedule of three bolus intravenous injections as outlined below.
Mesna injection is given as intravenous bolus injections in a dosage equal to 20% of the ifosfamide dosage weight by weight (w/w) at the time of ifosfamide administration and 4 and 8 hours after each dose of ifosfamide. The total daily dose of Mesna injection is 60% of the ifosfamide dose. The recommended dosing schedule is outlined below in Table 1.
1 The dosing schedule should be repeated on each day that ifosfamide is administered. When the dosage of ifosfamide is increased or decreased, the ratio of Mesna to ifosfamide should be maintained.
|0 Hours||4 Hours||8 Hours|
|Mesna Injection1||240 mg/m2||240 mg/m2||240 mg/m2|
Intravenous and Oral Dosing
Mesna injection may be given on a fractionated dosing schedule of a single bolus injection followed by two oral administrations of Mesna tablets as outlined below.
Mesna injection is given as intravenous bolus injections in a dosage equal to 20% of the ifosfamide dosage (w/w) at the time of ifosfamide administration. Mesna tablets are given orally in a dosage equal to 40% of the ifosfamide dose 2 and 6 hours after each dose of ifosfamide. The total daily dose of Mesna is 100% of the ifosfamide dose. The recommended dosing schedule is outlined in Table 2.
1 The dosing schedule should be repeated on each day that ifosfamide is administered. When the dosage of ifosfamide is increased or decreased, the ratio of Mesna to ifosfamide should be maintained.
|0 Hours||2 Hours||6 Hours|
|Mesna Injection1||240 mg/m2||-||-|
|Mesna Tablets||-||480 mg/m2||480 mg/m2|
The efficacy and safety of this ratio of intravenous and oral Mesna has not been established as being effective for daily doses of ifosfamide higher than 2 g/m2.
Patients who vomit within two hours of taking oral Mesna should repeat the dose or receive intravenous Mesna injection.
Monitoring of Hematuria
Maintain adequate hydration and sufficient urinary output, as required for ifosfamide treatment, and monitor urine for the presence of hematuria. If severe hematuria develops when Mesna injection is given according to the recommended dosage schedule, dosage reductions or discontinuation of ifosfamide therapy may be required.
Preparation for Intravenous Administration and Stability
Determine the volume of Mesna injection for the intended dose.
Dilute the volume of Mesna injection for the dose in any of the following fluids to obtain a final concentration of 20 mg per mL:
- 5% Dextrose Injection, USP
- 5% Dextrose and 0.2% Sodium Chloride Injection, USP
- 5% Dextrose and 0.33% Sodium Chloride Injection, USP
- 5% Dextrose and 0.45% Sodium Chloride Injection, USP
- 0.9% Sodium Chloride Injection, USP
- Lactated Ringer's Injection, USP
The Mesna injection multidose vials may be stored and used for up to 8 days after initial puncture.
Store diluted solutions at 25°C (77°F). Use diluted solutions within 24 hours.
Do not mix Mesna injection with epirubicin, cyclophosphamide, cisplatin, carboplatin, and nitrogen mustard.
The benzyl alcohol contained in Mesna injection vials can reduce the stability of ifosfamide. Ifosfamide and Mesna injection may be mixed in the same bag provided the final concentration of ifosfamide does not exceed 50 mg/mL. Higher concentrations of ifosfamide may not be compatible with Mesna injection and may reduce the stability of ifosfamide.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. Any solutions which are discolored, hazy, or contain visible particulate matter should not be used.
Dosage Forms and Strengths
- Mesna Injection: 10 mL Multi-Dose Vial, 1 gram per 10 mL (100 mg per mL)
Mesna injection is contraindicated in patients known to be hypersensitive to Mesna or to any of the excipients [see Warnings and Precautions (5.1)].
Warnings and Precautions
Mesna may cause systemic hypersensitivity reactions, including anaphylaxis. These reactions may include fever, cardiovascular symptoms (hypotension, tachycardia), acute renal impairment, hypoxia, respiratory distress, urticaria, angioedema, laboratory signs of disseminated intravascular coagulation, hematological abnormalities, increased liver enzymes, nausea, vomiting, arthralgia, and myalgia. These reactions may occur with the first exposure or after several months of exposure. Monitor for signs or symptoms. Discontinue Mesna and provide supportive care.
Drug rash with eosinophilia and systemic symptoms and bullous and ulcerative skin and mucosal reactions, consistent with Stevens-Johnson syndrome or toxic epidermal necrolysis have occurred. Mesna may cause skin and mucosal reactions characterized by urticaria, rash, erythema, pruritus, burning sensation, angioedema, periorbital edema, flushing and stomatitis. These reactions may occur with the first exposure or after several months of exposure. Discontinue Mesna and provide supportive care.
Benzyl Alcohol Toxicity
Benzyl alcohol, a preservative in Mesna injection, has been associated with serious adverse reactions and death (including gasping syndrome) in neonates, premature, and low-birth weight infants. The minimum amount of benzyl alcohol at which toxicity may occur is not known. Consider the combined daily metabolic load of benzyl alcohol from all sources when prescribing Mesna injection (10.4 mg benzyl alcohol per mL). Neonates, premature, and low-birth weight infants, as well as patients receiving high dosages, may be more likely to develop toxicity. Monitor patients for signs or symptoms of toxicity. Avoid use in neonates, premature, and low-birth weight infants [see Use in Specific Populations (8.4)].
Laboratory Test Interferences
False-Positive Urine Tests for Ketone Bodies
A false positive test for urinary ketones may arise in patients treated with Mesna injection when using nitroprusside sodium-based urine tests (including dipstick tests). The addition of glacial acetic acid can be used to differentiate between a false positive result (cherry-red color that fades) and a true positive result (red-violet color that intensifies).
False-Negative Tests for Enzymatic CPK Activity
Mesna may interfere with enzymatic creatinine phosphokinase (CPK) activity tests that use a thiol compound (e.g., N-acetylcysteine) for CPK reactivation. This may result in a falsely low CPK level.
False-Positive Tests for Ascorbic Acid
Mesna may cause false-positive reactions in Tillman's reagent-based urine screening tests for ascorbic acid.
Use in Patients with a History of Adverse Reactions to Thiol Compounds
Mesna is a thiol compound, i.e., a sulfhydryl (SH) group-containing organic compound. Hypersensitivity reactions to Mesna and to amifostine, another thiol compound, have been reported. It is not clear whether patients who experienced an adverse reaction to a thiol compound are at increased risk for a hypersensitivity reaction to Mesna.
The following are discussed in more detail in other sections of the labeling.
- Hypersensitivity Reactions [see Warnings and Precautions (5.1)]
- Dermatological Toxicity [see Warnings and Precautions (5.2)]
- Benzyl Alcohol Toxicity [see Warnings and Precautions (5.3)]
- Laboratory Test Interferences [see Warnings and Precautions (5.4)]
- Use in Patients with a History of Adverse Reactions to Thiol Compounds [see Warnings and Precautions (5.5)]
Clinical Trials Experience
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Mesna injection adverse reaction data are available from four Phase 1 studies in which single intravenous doses of 600 to 1,200 mg Mesna injection without concurrent chemotherapy were administered to a total of 53 healthy volunteers and single oral doses of 600 to 2,400 mg of Mesna tablets were administered to a total of 82 healthy volunteers. The most frequently reported side effects (observed in two or more healthy volunteers) for healthy volunteers receiving single doses of Mesna injection alone were headache, injection site reactions, flushing, dizziness, nausea, vomiting, somnolence, diarrhea, anorexia, fever, pharyngitis, hyperesthesia, influenza-like symptoms, and coughing. In two Phase 1 multiple-dose studies where healthy volunteers received Mesna tablets alone or intravenous Mesna followed by repeated doses of Mesna tablets, flatulence and rhinitis were reported. In addition, constipation was reported by healthy volunteers who had received repeated doses of intravenous Mesna injection.
Additional adverse reactions in healthy volunteers receiving Mesna injection alone included injection site reactions, abdominal pain/colic, epigastric pain/burning, mucosal irritation, lightheadedness, back pain, arthralgia, myalgia, conjunctivitis, nasal congestion, rigors, paresthesia, photophobia, fatigue, lymphadenopathy, extremity pain, malaise, chest pain, dysuria, pleuritic pain, dry mouth, dyspnea, and hyperhidrosis. In healthy volunteers, Mesna was commonly associated with a rapid (within 24 hours) decrease in lymphocyte count, which was generally reversible within one week of administration.
Because Mesna is used in combination with ifosfamide or ifosfamide-containing chemotherapy regimens, it is difficult to distinguish the adverse reactions which may be due to Mesna from those caused by the concomitantly administered cytotoxic agents.
Adverse reactions reasonably associated with Mesna administered intravenously and orally in four controlled studies in which patients received ifosfamide or ifosfamide-containing regimens are presented in Table 3.

The following adverse reactions have been reported in the postmarketing experience of patients receiving Mesna in combination with ifosfamide or similar drugs, making it difficult to distinguish the adverse reactions which may be due to Mesna from those caused by the concomitantly administered cytotoxic agents. Because these reactions are reported from a population of unknown size, precise estimates of frequency cannot be made.
Nervous System: Convulsion
No clinical drug interaction studies have been conducted with Mesna injection.
USE IN SPECIFIC POPULATIONS
Pregnancy Category B.
There are no studies of Mesna in pregnant women. Reproduction studies performed in rats and rabbits at oral doses approximately 10 times the maximum recommended total daily intravenous-oral-oral human dose on a body surface area basis (1,000 mg/kg in rabbits and 2,000 mg/kg in rats) revealed no evidence of harm to the fetus due to Mesna. The incidence of malformations in human pregnancies has not been established for Mesna. All pregnancies, regardless of drug exposure, have a background rate of 2 to 4% for major malformations and 15 to 20% for pregnancy loss. Because animal reproductive studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.
It is not known whether Mesna or diMesna is excreted in human milk. Benzyl alcohol present in maternal serum is likely to cross into human milk and may be orally absorbed by a nursing infant. Because many drugs are excreted in human milk and because of the potential for adverse reactions in nursing infants from Mesna, a decision should be made whether to discontinue nursing or discontinue the drug, taking into account the importance of the drug to the mother.
Safety and effectiveness of Mesna injection in pediatric patients have not been established. Mesna injection contains benzyl alcohol (10.4 mg benzyl alcohol per mL) which has been associated with serious adverse reactions and death in pediatric patients. The "gasping syndrome," (characterized by central nervous system depression, metabolic acidosis and gasping respirations) has been associated with benzyl alcohol dosages >99 mg/kg/day in neonates, premature, and low-birth weight infants. Additional symptoms may include gradual neurological deterioration, seizures, intracranial hemorrhage, hematologic abnormalities, skin breakdown, hepatic and renal failure, hypotension, bradycardia, and cardiovascular collapse. The minimum amount of benzyl alcohol at which toxicity may occur is not known. Neonates, premature, and low-birth weight infants, as well as patients receiving high dosages, may be more likely to develop toxicity. Practitioners administering this and other medications containing benzyl alcohol should consider the combined daily metabolic load of benzyl alcohol from all sources [see Warnings and Precautions (5.3)].
Clinical studies of Mesna injection did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. In general, dose selection for an elderly patient should be cautious, reflecting the greater frequency of decreased hepatic, renal, or cardiac function, and of concomitant disease or other drug therapy. The ratio of ifosfamide to Mesna should remain unchanged.
Use in Patients with Renal Impairment
No clinical studies were conducted to evaluate the effect of renal impairment on the pharmacokinetics of Mesna injection.
Use in Patients with Hepatic Impairment
No clinical studies were conducted to evaluate the effect of hepatic impairment on the pharmacokinetics of Mesna injection.
There is no known antidote for Mesna injection.
In a clinical trial, 11 patients received intravenous Mesna injection 10 mg/kg to 66 mg/kg per day for 3 to 5 days. Patients also received ifosfamide or cyclophosphamide. Adverse reactions included nausea, vomiting, diarrhea and fever. An increased rate of these adverse reactions has also been found in oxazaphosphorine-treated patients receiving ≥80 mg Mesna injection per kg per day intravenously compared with patients receiving lower doses or hydration treatment only.
Postmarketing, administration of 4.5 grams to 6.9 grams of Mesna resulted in hypersensitivity reactions including mild hypotension, shortness of breath, asthma exacerbation, rash, and flushing.
Mesna injection is a detoxifying agent to inhibit the hemorrhagic cystitis induced by ifosfamide. The active ingredient, Mesna, is a synthetic sulfhydryl compound designated as sodium-2-mercaptoethane sulfonate with a molecular formula of C2H5NaO3S2 and a molecular weight of 164.18. Its structural formula is as follows:
Mesna Injection is a sterile, nonpyrogenic, aqueous solution of clear and colorless appearance in clear glass multidose vials for intravenous administration. Mesna Injection contains 100 mg per mL Mesna, 0.25 mg per mL edetate disodium and sodium hydroxide for pH adjustment. Mesna Injection Multi-Dose Vials also contain 10.4 mg per mL of benzyl alcohol as a preservative. The solution has a pH range of between 7.5 and 8.5.
Mesna - Clinical Pharmacology
Mechanism of Action
Mesna reacts chemically with the urotoxic ifosfamide metabolites, acrolein and 4-hydroxy-ifosfamide, resulting in their detoxification. The first step in the detoxification process is the binding of Mesna to 4-hydroxy-ifosfamide forming a non-urotoxic 4-sulfoethylthioifosfamide. Mesna also binds to the double bonds of acrolein and to other urotoxic metabolites and inhibits their effects on the bladder.
Following oral administration, peak plasma concentrations were reached within 1.5 to 4 hours and 3 to 7 hours for free Mesna and total Mesna (Mesna plus diMesna and mixed disulfides), respectively. Oral bioavailability averaged 58% (range 45 to 71%) for free Mesna and 89% (range 74 to 104%) for total Mesna based on plasma AUC data from 8 healthy volunteers who received 1,200 mg oral or intravenous doses.
Food does not affect the urinary availability of orally administered Mesna.
Mean apparent volume of distribution (Vd) for Mesna is 0.652 ± 0.242 L/kg after intravenous administration which suggests distribution to total body water (plasma, extracellular fluid, and intracellular water).
Analogous to the physiological cysteine-cystine system, Mesna is rapidly oxidized to its major metabolite, Mesna disulfide (diMesna). Plasma concentrations of Mesna exceed those of diMesna after oral or intravenous administration.
Following intravenous administration of a single 800 mg dose, approximately 32% and 33% of the administered dose was eliminated in the urine in 24 hours as Mesna and diMesna, respectively. Mean plasma elimination half-lives of Mesna and diMesna are 0.36 hours and 1.17 hours, respectively. Mesna has a plasma clearance of 1.23 L/h/kg.
Carcinogenesis, Mutagenesis, Impairment of Fertility
No long-term studies in animals have been performed to evaluate the carcinogenic potential of Mesna.
Mesna was not genotoxic in the in vitro Ames bacterial mutagenicity assay, the in vitro mammalian lymphocyte chromosomal aberration assay or the in vivo mouse micronucleus assay.
No studies on male or female fertility were conducted. No signs of male or female reproductive organ toxicity were seen in 6-month oral rat studies (≤2,000 mg/kg/day) or 29-week oral dog studies (520 mg/kg/day) at doses approximately 10-fold higher than the maximum recommended human dose on a body surface area basis.
Intravenous Mesna Injection
Hemorrhagic cystitis produced by ifosfamide is dose dependent (Table 4). At a dose of 1.2 g/m2 ifosfamide administered daily for 5 days, 16 to 26% of the patients who received conventional uroprophylaxis (high fluid intake, alkalinization of the urine, and the administration of diuretics) developed hematuria (>50 RBC per hpf or macrohematuria) (Studies 1, 2, and 3). In contrast, none of the patients who received Mesna injection together with this dose of ifosfamide developed hematuria (Studies 3 and 4). In two randomized studies, (Studies 5 and 6), higher doses of ifosfamide, from 2 g/m2 to 4 g/m2 administered for 3 to 5 days, produced hematuria in 31 to 100% of the patients. When Mesna injection was administered together with these doses of ifosfamide, the incidence of hematuria was less than 7%.
*Ifosfamide dose 1.2 g/m2 d x 5
†Ifosfamide dose 2 g/m2 to 4 g/m2 d x 3 to 5
|Study||Conventional Uroprophylaxis (number of patients)||Standard Mesna Intravenous Regimen (number of patients)|
|Study 1||16% (7/44)||-|
|Study 2||26% (11/43)||-|

|Study 5||31% (14/46)||6% (3/46)|
|Study 6||100% (7/7)||0% (0/8)|
Clinical studies comparing recommended intravenous and oral Mesna dosing regimens demonstrated incidences of grade 3 to 4 hematuria of <5%. Study 7 was an open label, randomized, two-way crossover study comparing three intravenous doses with an initial intravenous dose followed by two oral doses of Mesna in patients with cancer treated with ifosfamide at a dose of 1.2 g/m2 to 2.0 g/m2 for 3 to 5 days. Study 8 was a randomized, multicenter study in cancer patients receiving ifosfamide at 2.0 g/m2 for 5 days. In both studies, development of grade 3 or 4 hematuria was the primary efficacy endpoint. The percent of patients developing hematuria in each of these studies is presented in Table 5.

Mesna (MESS-nah) Injection
What is the most important information I should know about Mesna injection?
Mesna injection can cause serious allergic reactions and skin reactions. These side effects can happen the first time you are treated with Mesna injection, or after several months of treatment with Mesna injection. Stop treatment with Mesna injection and call your doctor or go to the nearest hospital emergency room right away if you develop any of the symptoms listed below:
See “What are the possible side effects of Mesna injection?” for more information about side effects.
What is Mesna injection?
Mesna injection is a prescription medicine used to reduce the risk of inflammation and bleeding of the bladder (hemorrhagic cystitis) in people who receive ifosfamide (a medicine used to treat cancer).
Mesna injection is not for use to reduce the risk of blood in the urine (hematuria) due to other medical conditions.
It is not known if Mesna injection is safe and effective in children.
Who should not receive Mesna injection?
Do not take Mesna injection if you are allergic to Mesna injection or any of the ingredients in Mesna injection. See the end of this leaflet for a complete list of ingredients in Mesna injection.
What should I tell my doctor before receiving Mesna injection?
Before you receive Mesna injection, tell your doctor if you:
- have any other medical conditions
- are pregnant or plan to become pregnant. It is not known if Mesna injection will harm your unborn baby.
- are breastfeeding or plan to breastfeed. It is not known if Mesna passes into your breast milk. You and your doctor should decide if you will receive Mesna injection or breastfeed. You should not do both.
Tell your doctor about all the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements.
How will I receive Mesna injection?
- Mesna is given on the same day that you receive ifosfamide.
- Mesna can be given by an intravenous (IV) infusion into a vein or tablets taken by mouth.
- You will receive Mesna in one of two ways:
- Mesna intravenous (IV) infusion into a vein at the time you receive ifosfamide and 4 and 8 hours after you receive ifosfamide.
- Mesna intravenous (IV) infusion into a vein at the time you receive ifosfamide and Mesna tablets taken by mouth 2 and 6 hours after you receive ifosfamide.
- Take Mesna tablets at the exact times and the exact dose your doctor tells you to take it.
- You may need to take half of a Mesna tablet for your complete dose. Each tablet has a groove in the middle that will make it easier to break the tablet in half.
- During treatment with Mesna, you should drink 4 to 8 cups of liquid (1 to 2 liters) each day, whether you receive Mesna by intravenous infusion or take Mesna tablets by mouth.
- Tell your doctor if you:
- vomit within 2 hours of taking Mesna tablets by mouth
- miss a dose of Mesna tablets
- have pink or red colored urine
What are the possible side effects of Mesna injection?
Mesna injection may cause serious side effects, including:
See “What is the most important information I should know about Mesna injection?”
- Mesna injection that is given by intravenous infusion contains the preservative benzyl alcohol. Benzyl alcohol has been shown to cause serious side effects and death in newborn, premature, and low-birth weight babies.
