🩺 Clinical
Methoxy polyethylene glycol-epoetin beta injection is used to treat anemia (a lower than normal number of red blood cells) in people with chronic kidney failure (condition in which the kidneys slowly and permanently stop working over a period of time) in adults on and not on dialysis and in children 5 years of age and older on dialysis who have already received another treatment for anemia. Methoxy polyethylene glycol-epoetin beta injection should not be used to treat anemia caused by cancer chemotherapy and should not be used in place of a red blood cell transfusion to treat severe anemia.

⏳ Availability & biosimilar status
Biologics have no small-molecule generics; biosimilar competition is tracked in the FDA Purple Book.
Why the date isn’t exact: Biosimilar timing can change because patents may be challenged, settled, licensed, added or removed, and litigation can move the real date earlier or later.
🛈 What do these terms mean?
- Biologic patent
- A patent the reference product’s maker has publicly listed. A biosimilar generally can’t launch until these expire — unless they’re invalidated or resolved in a settlement.
- Reference-product exclusivity
- A flat 12 years of FDA market protection from the biologic’s first licensure (the BPCIA). No biosimilar can be licensed before it ends, regardless of patents.
- Interchangeable exclusivity
- The first interchangeable biosimilar can earn a period as the only interchangeable version (pharmacists can substitute it without the prescriber).
- Earliest biosimilar (LOE)
- The latest of all the dates above — the soonest a biosimilar can realistically reach the market. Litigation and settlements can move it earlier.
Biologics have no small-molecule “generics” — competition comes from FDA-licensed biosimilars, tracked in the FDA Purple Book.

Cancer: • Mircera is not indicated and is not recommended for the treatment of anemia due to cancer chemotherapy. A dose-ranging study of Mircera was terminated early because of more deaths among patients receiving Mircera than another ESA ( 5.2 ). • ESAs shortened overall survival and/or increased the risk of tumor progression or recurrence in clinical studies in patients with breast, non-small cell lung, head and neck, lymphoid, and cervical cancers ( 5.2 ). Chronic Kidney Disease [see Warnings and Precautions ( 5.1 )] • In controlled trials, patients experienced greater risks for death, serious adverse cardiovascular reactions, and stroke when administered erythropoiesis-stimulating agents (ESAs) to target a hemoglobin level of greater than 11 g/dL. • No trial has identified a hemoglobin target level, ESA dose, or dosing strategy that does not increase these risks. • Use the lowest Mircera dose sufficient to reduce the need for red blood cell (RBC) transfusions.
Cancer [see Warnings and Precautions ( 5.2 )] • Mircera is not indicated and is not recommended for the treatment of anemia due to cancer chemotherapy. A dose-ranging study of Mircera was terminated early because of more deaths among patients receiving Mircera than another ESA. • ESAs have shown shortened overall survival and/or increased the risk of tumor progression or recurrence in clinical studies in patients with breast, non-small cell lung, head and neck, lymphoid, and cervical cancers.
🎯 Indications and Usage ▾
1 INDICATIONS AND USAGE Mircera is an erythropoiesis-stimulating agent (ESA) indicated for the treatment of anemia associated with chronic kidney disease (CKD) in: • adult patients on dialysis and adult patients not on dialysis ( 1.1 ). • pediatric patients 3 months to 17 years of age on dialysis or not on dialysis who are converting from another ESA after their hemoglobin level was stabilized with an ESA ( 1.1 ). Limitations of Use Mircera is not indicated and is not recommended for use: • In the treatment of anemia due to cancer chemotherapy ( 5.2 ). • As a substitute for RBC transfusions in patients who require immediate correction of anemia ( 12.2 ).
Mircera has not been shown to improve quality of life, fatigue, or patient well-being.
1.1Anemia Due to Chronic Kidney Disease Mircera is indicated for the treatment of anemia associated with chronic kidney disease (CKD) in: • adult patients on dialysis and adult patients not on dialysis. • pediatric patients 3 months to 17 years of age on dialysis or not on dialysis who are converting from another ESA after their hemoglobin level was stabilized with an ESA. Limitations of Use Mircera is not indicated and is not recommended: • In the treatment of anemia due to cancer chemotherapy [see Warnings and Precautions ( 5.2 )] . • As a substitute for RBC transfusions in patients who require immediate correction of anemia [see Clinical Pharmacology ( 12.2 )] .
Mircera has not been shown to improve symptoms, physical functioning, or health-related quality of life.
⏱️ Dosage and Administration ▾
2 DOSAGE AND ADMINISTRATION Mircera is administered by subcutaneous or intravenous injection ( 2.2 ). Adult Patients • Initial Treatment: (patients not currently treated with an ESA): • CKD patients on dialysis: 0.6 mcg/kg body weight administered once every two weeks ( 2.2 ). • CKD patients not on dialysis: 1.2 mcg/kg body weight administered once every month as a single subcutaneous injection. Alternatively, a starting dose of 0.6 mcg/kg body weight may be administered once every two weeks as a single intravenous or subcutaneous injection ( 2.2 ). • Conversion from Another ESA: • Dosed once monthly or once every two weeks based on total weekly epoetin alfa or darbepoetin alfa dose at time of conversion ( 2.2 ).
Pediatric Patients • Conversion from another ESA: dosed once every 4 weeks based on total weekly epoetin alfa or darbepoetin alfa dose at time of conversion ( 2.2 ). • In patients less than 6 years of age, maintain the same route of administration as the previous ESA when switching from another ESA to Mircera.
2.1Important Dosing Information Evaluation of Iron Stores and Nutritional Factors Evaluate the iron status in all patients before and during treatment. Administer supplemental iron therapy when serum ferritin is less than 100 mcg/L or when serum transferrin saturation is less than 20%. The majority of patients with CKD will require supplemental iron during the course of ESA therapy.
Monitoring of Response to Therapy Correct or exclude other causes of anemia (e.g., vitamin deficiency, metabolic or chronic inflammatory conditions, bleeding, etc.) before initiating Mircera [see Warnings and Precautions ( 5.9 )]. Following initiation of therapy and after each dose adjustment, monitor hemoglobin weekly until the hemoglobin level is stable and sufficient to minimize the need for RBC transfusion. Individualization of Dosing Individualize and use the lowest dose of Mircera sufficient to reduce the need for RBC transfusions [see Warnings and Precautions ( 5.1 )] .
In controlled trials, patients experienced greater risks for death, serious adverse cardiovascular reactions, and stroke when administered erythropoiesis-stimulating agents (ESAs) to target a hemoglobin level of greater than 11 g/dL for adult patients. No trial has identified a hemoglobin target level, ESA dose, or dosing strategy that does not increase these risks. Physicians and patients should weigh the possible benefits of decreasing transfusions against the increased risks of death and other serious cardiovascular adverse events [see Boxed Warning and Clinical Studies ( 14 )] .
2.2For Adult Patients with CKD Prefilled syringes are not designed for administration of partial doses. Round doses to the closest dose achievable with the prefilled syringes. When initiating or adjusting therapy, monitor hemoglobin levels at least weekly until stable, then monitor at least monthly.
When adjusting therapy consider hemoglobin rate of rise, rate of decline, ESA responsiveness and hemoglobin variability. A single hemoglobin excursion may not require a dosing change. • Do not increase the dose more frequently than once every 4 weeks. Decreases in dose can occur more frequently.
Avoid frequent dose adjustments. • If the hemoglobin rises rapidly (e.g., more than 1 g/dL in any 2-week period), reduce the dose of Mircera by approximately 25% to the closest dose achievable with the prefilled syringes to reduce rapid responses. • If the hemoglobin continues to rise following a dose reduction, discontinue Mircera until the hemoglobin level begins to decrease, at which point therapy should be restarted with a dose that is approximately 25% below the previously administered dose. • For patients who do not respond adequately, if the hemoglobin has not increased by more than 1 g/dL after 4 weeks of therapy, increase the dose by approximately 25% to the closest dose achievable with the prefilled syringes. • For patients who do not respond adequately over a 12-week escalation perio…

⛔ Contraindications ▾
4 CONTRAINDICATIONS Mircera is contraindicated in patients with: • Uncontrolled hypertension [see Warnings and Precautions ( 5.3 )] • Pure red cell aplasia (PRCA) that begins after treatment with Mircera or other erythropoietin protein drugs [see Warnings and Precautions ( 5.6 )] • History of serious or severe allergic reactions to Mircera (e.g., anaphylactic reactions, angioedema, bronchospasm, skin rash, and urticaria) [see Warnings and Precautions ( 5.7 , 5.8 )] . • Uncontrolled hypertension ( 4 ). • Pure red cell aplasia (PRCA) that begins after treatment with Mircera or other erythropoietin protein drugs ( 4 ). • History of serious allergic reactions to Mircera, including anaphylaxis ( 4 ).
⚠️ Warnings and Cautions ▾
5 WARNINGS AND PRECAUTIONS • Hypertension: Control hypertension prior to initiating and during treatment with Mircera ( 5.3 ). • Seizures: Seizures have occurred in CKD patients participating in Mircera clinical studies. Increase monitoring of these patients for changes in seizure frequency or premonitory symptoms ( 5.4 ). • PRCA: If severe anemia and low reticulocyte count develop during Mircera treatment, withhold Mircera and evaluate for PRCA ( 5.6 ). • Serious Allergic Reactions: Discontinue Mircera and manage reactions ( 5.7 ). • Severe Cutaneous Reactions: Discontinue Mircera ( 5.8 ).
5.1Increased Mortality, Myocardial Infarction, Stroke, and Thromboembolism • In controlled clinical trials of patients with CKD comparing higher hemoglobin targets (13 to 14 g/dL) to lower targets (9 to 11.3 g/dL), ESAs increased the risk of death, myocardial infarction, stroke, congestive heart failure, thrombosis of hemodialysis vascular access, and other thromboembolic events in the higher target groups. • Using ESAs to target a hemoglobin level of greater than 11 g/dL increases the risk of serious adverse cardiovascular reactions and has not been shown to provide additional benefit [see Clinical Studies ( 14 )] .
Use caution in patients with coexistent cardiovascular disease and stroke [see Dosage and Administration ( 2.2 )] . Patients with CKD and an insufficient hemoglobin response to ESA therapy may be at even greater risk for cardiovascular reactions and mortality than other patients. A rate of hemoglobin rise of greater than 1 g/dL over 2 weeks may contribute to these risks. • In controlled clinical trials of patients with cancer, ESAs increased the risks for death and serious adverse cardiovascular reactions.
These adverse reactions included myocardial infarction and stroke. • In controlled clinical trials, ESAs increased the risk of death in patients undergoing coronary artery bypass graft surgery (CABG) and the risk of deep venous thrombosis (DVT) in patients undergoing orthopedic procedures. The design and overall results of the 3 large trials comparing higher and lower hemoglobin targets are shown in Table 4 (Normal Hematocrit Study (NHS), Correction of Hemoglobin Outcomes in Renal Insufficiency (CHOIR) and Trial to Reduce Cardiovascular Events with Aranesp ® Therapy (TREAT)).

6.1Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of Mircera cannot be directly compared to rates in the clinical trials of other drugs and may not reflect the rates observed in practice. Adult Patients The data described below reflect exposure to Mircera in 2737 patients, including 1451 exposed for 6 months and 1144 exposed for greater than one year. Mircera was studied primarily in active-controlled studies (n=1789 received Mircera, and n=948 received another ESA) and in long-term follow up studies.
The population was 18 to 92 years of age, 58% male, and the percentage of Caucasian, Black (including African Americans), Asian and Hispanic patients were 73%, 20%, 5%, and 9%, respectively. Approximately 85% of the patients were receiving dialysis. Most patients received Mircera using dosing regimens of once every two or four weeks, administered subcutaneously or intravenously.
The most commonly reported adverse reactions in ≥10% of patients were hypertension [see Warnings and Precautions ( 5.3 )] , diarrhea, and nasopharyngitis. The most common adverse reactions that led to treatment discontinuation in the Mircera clinical studies were: hypertension, coronary artery disease, anemia, concomitant termination of other CKD therapy and septic shock. Some of the adverse reactions reported are typically associated with CKD, or recognized complications of dialysis, and may not necessarily be attributable to Mircera therapy.
Adverse reaction rates did not importantly differ between patients receiving Mircera or another ESA. Table 6 summarizes the most frequent adverse reactions (≥5%) in patients treated with Mircera. Table 6: Adverse Reactions Occurring in ≥ 5% of CKD Patients BODY SYSTEM Adverse Reaction Patients Treated with Mircera (n=1789) VASCULAR Hypertension 13% Hypotension 5% GASTROINTESTINAL Diarrhea 11% Vomiting 6% Constipation 5% INFECTIONS AND INFESTATIONS Nasopharyngitis 11% Upper Respiratory Tract Infection 9% Urinary Tract Infection 5% NERVOUS SYSTEM Headache 9% MUSCULOSKELETAL AND CONNECTIVE TISSUE Muscle Spasms 8% Back Pain 6% Pain in Extremity 5% INJURY, POISONING AND PROCEDURAL COMPLICATIONS Procedural Hypotension 8% Arteriovenous Fistula Thrombosis 5% Arteriovenous Fistula Site Complication 5% METABOLISM AND NUTRITION Fluid Overload 7% RESPIRATORY, THORACIC AND MEDIASTINAL Cough 6% In the controlled trials, the rates of serious adverse reactions did not importantly differ between patients receiving Mircera and another ESA (38% vs.
42%) except for the occurrence of serious gastrointestinal hemorrhage (1.2% vs. 0.2%). Serious hemorrhagic adverse reactions of all types occurred among 5% and 4% of patients receiving Mircera or another ESA, respectively.
Pediatric Patients In an open-label, multiple dose study, 64 pediatric patients (ages 5 to 17 years) with CKD who were on hemodialysis and who had stable hemoglobin levels while previously receiving another ESA (epoetin alfa/beta or darbepoetin alfa) were then converted to Mircera administered…
👥 Use in Specific Populations ▾
8 USE IN SPECIFIC POPULATIONS
8.1Pregnancy Risk Summary Available data from a small number of published case reports and postmarketing experience with Mircera use in pregnancy are insufficient to identify a drug associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. Chronic kidney disease is associated with maternal and embryo-fetal risks (see Clinical Considerations) . In animal reproduction studies, administration of methoxy polyethylene glycol-epoetin beta to rats and rabbits during pregnancy and lactation adversely affected offspring at doses 17-fold and greater than the recommended human dose (see Data) .
The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risks of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.
Clinical Considerations Disease Associated Maternal and/or Embryo-Fetal Risk Pregnancy in women with chronic kidney disease has been associated with adverse outcomes including hypertension, pre-eclampsia, miscarriage, premature birth, low-birth-weight, polyhydramnios, and intrauterine growth restriction. Data When methoxy polyethylene glycol-epoetin beta was administered subcutaneously to rats and rabbits during gestation (including the period of organogenesis), bone malformation was observed in both species at 50 mcg/kg once every three days (corresponding to 500 mcg/kg/month or 417-fold the recommended human dose) in studies of embryo-fetal development.
This effect was observed as missing caudal vertebrae resulting in a thread-like tail in one rat fetus, absent first digit metacarpal and phalanx on each forelimb resulting in absent pollex in one rabbit fetus, and fused fourth and fifth cervical vertebrae centra in another rabbit fetus. Dose-related reduction in fetal weights was observed in both rats and rabbits. At doses 5 mcg/kg once every three days and higher, corresponding to 50 mcg/kg/month or 42-fold the recommended human dose, methoxy polyethylene glycol-epoetin beta caused exaggerated pharmacodynamic effects in dams.
Once-weekly doses of methoxy polyethylene glycol-epoetin beta up to 50 mcg/kg/dose (corresponding to 200 mcg/kg/month or 167-fold the recommended human dose) given to pregnant and lactating rats did not adversely affect pregnancy parameters, natural delivery or litter observations in a study of pre-and postnatal development. Increased deaths and significant reduction in the growth rate of the F1 generation were observed during lactation and early post weaning period at 20 and 50 mcg/kg/dose, corresponding to 80 and 200 mcg/kg/month or 67- and 167-fold the recommended human dose.
A significant reduction in the growth rate of the F1 generation was evident already at 5 mcg/kg/dose, corresponding to 20 mcg/kg/month or 17-fold the recommended human dose. However, no remarkable effect on reflex, physical and cognitive development or reproductive performance was observed in F1 generation of any dose groups. The dose level not causing any adverse effect on dams or offspring was not determined.
8.2Lactation Risk Summary There are no data on the presence of methoxy polyethylene glycol-epoetin beta in human milk, the effects on the breastfed child, or the effects on milk production. However, endogenous erythropoietin is present in human milk. In rats, methoxy polyethylene glycol-epoetin beta was present in maternal milk (see Data) .
When a drug is present in animal milk, it is likely that the drug will be present in human milk. The lack of clinical data during lactation precludes a clear determination of the risk of Mircera to a child during lactation. Therefore, the developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Mircera and any pote…

🧒 Pediatric Use ▾
8.4Pediatric Use The safety and effectiveness of intravenous and subcutaneous Mircera for the treatment of anemia due to CKD have been established in pediatric patients 3 months to 17 years of age on dialysis and not on dialysis who are converting from another ESA after their hemoglobin level was stabilized with an ESA. The use of Mircera in this pediatric age group is supported by evidence from adequate and well-controlled studies of Mircera in adults, a dose-finding study in 64 pediatric patients 5 to 17 years of age with CKD on hemodialysis and a subcutaneous dose-finding study in 40 patients 3 months to 17 years of age with CKD on dialysis or not on dialysis.
The adverse reaction profile observed in pediatric patients was consistent with the safety profile found in adults. The safety and effectiveness of Mircera have not been established in patients less than 3 months of age [see Adverse Reactions ( 6.1 ) and Clinical Studies ( 14.2 )] . The safety and effectiveness of Mircera have not been established for treatment of anemia in pediatric patients whose hemoglobin level has not been previously stabilized by treatment with an ESA.

8.5Geriatric Use Clinical studies of Mircera did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently from younger subjects. Other reported clinical experience has not identified differences in responses between the elderly and younger patients. In general, dose selection for an elderly patient should be cautious, usually starting at the low end of the dosing range, reflecting the greater frequency of decreased hepatic, renal, or cardiac function and of concomitant disease or other drug therapy.
🆘 Overdosage ▾
10 OVERDOSAGE Mircera overdosage can elevate hemoglobin levels above the desired level, which should be managed with discontinuation or reduction of Mircera dosage and/or with phlebotomy, as clinically indicated [see Pharmacodynamics ( 12.2 )]. Cases of severe hypertension have been observed following overdose with ESAs [see Warnings and Precautions ( 5.3 )].
🧬 Clinical Pharmacology ▾
12 CLINICAL PHARMACOLOGY
12.1Mechanism of Action Mircera is an erythropoietin receptor activator with greater activity in vivo as well as increased half-life, in contrast to erythropoietin. A primary growth factor for erythroid development, erythropoietin is produced in the kidney and released into the bloodstream in response to hypoxia. In responding to hypoxia, erythropoietin interacts with erythroid progenitor cells to increase red cell production.
Production of endogenous erythropoietin is impaired in patients with CKD and erythropoietin deficiency is the primary cause of their anemia.
12.2Pharmacodynamics Following a single-dose of Mircera in adult patients with CKD, the onset of hemoglobin increase (defined as an increase more than 0.4 g/dL from baseline) was observed 7 to 15 days following initial dose administration [see Dosage and Administration ( 2.2 )] .
12.3Pharmacokinetics The pharmacokinetics of methoxy polyethylene glycol-epoetin beta were studied in adult anemic patients with CKD including patients on dialysis and those not on dialysis. Parameters are presented as the geometric mean [% coefficient of variation (%CV)] unless otherwise specified. Methoxy polyethylene glycol-epoetin beta did not accumulate following administration every four weeks.
However, when Mircera was administered every 2 weeks, serum concentrations at steady state increased by 12%. Multiple dosing had no effect on clearance, volume of distribution or bioavailability of methoxy polyethylene glycol-epoetin beta. Absorption Following the subcutaneous administration of Mircera, the maximum serum concentrations of methoxy polyethylene glycol-epoetin beta were observed at a median [min, max] time of 72 [24, 192] hours.
The absolute bioavailability of Mircera after the subcutaneous administration was 62%. Distribution The volume of distribution at steady state was 61 [46%] mL/kg. Elimination Following an intravenous administration of Mircera 0.4 mcg/kg body weight to patients with CKD receiving peritoneal dialysis, the observed terminal half-life was 119 [55%] hours, and the total systemic clearance was 0.47 [35%] mL/hr/kg.
Following a subcutaneous administration of Mircera 0.8 mcg/kg to CKD patients receiving peritoneal dialysis, the terminal half-life was 124 [57%] hours. Specific Populations The pharmacokinetics of methoxy polyethylene glycol-epoetin beta were not altered by age (range: 6-89 years), gender, race, severe hepatic impairment (Child-Pugh Class C), site of subcutaneous injection (abdomen, arm or thigh), or the use of dialysis. Pediatric Patients A population pharmacokinetic analysis was performed with data from 103 pediatric patients ages 6 months to 17 years and 524 adult patients.
Pediatric patients received Mircera intravenously (N=63, all on hemodialysis) or subcutaneously (total N=40, n=17 on pre-dialysis, n=18 on peritoneal dialysis and n=5 on hemodialysis). The covariate analysis showed a positive body weight effect on clearance (CL) and volume of distribution (V), and a positive age effect on V. Once those covariate effects were taken into account together with the addition of a pediatric subcutaneous bioavailability of 67%, compared to 31% in adults, no differences could be observed in the pharmacokinetic properties of Mircera in pediatric patients compared to adult patients.
12.6Immunogenicity The observed incidence of anti-drug antibodies is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of anti-drug antibodies in the studies described below with the incidence of anti-drug antibodies in other studies, including those of Mircera or of other methoxy polyethylene glycol-epoetin beta products. Neutralizing antibodies to Mircera that cross-react with endogenous erythropoietin and other ESAs can result in PRCA or severe anemia (with or without other cytopenias) [see Warnings and Precautions ( 5.6 )] .

📋 Description ▾
11 DESCRIPTION Methoxy polyethylene glycol-epoetin beta, is an ESA which differs from erythropoietin through formation of a chemical bond between either the N-terminal amino group or the ε-amino group of any lysine present in erythropoietin, predominantly Lys 52 and Lys 45 , and methoxy polyethylene glycol (PEG) butanoic acid (approximately 30,000 daltons). This results in a total molecular weight of approximately 60,000 daltons. Methoxy polyethylene glycol-epoetin beta is produced in Chinese hamster ovary (CHO) cells using recombinant DNA technology.

💬 Medication Guide ▾
MEDICATION GUIDE MIRCERA ® (mir-SER-ah) (methoxy polyethylene glycol-epoetin beta) injection, for intravenous or subcutaneous use Read this Medication Guide: • before you start Mircera. • if you are told by your healthcare provider that there is new information about Mircera. • if you are told by your healthcare provider that you may inject Mircera at home, read this Medication Guide each time you receive a new supply of medicine. This Medication Guide does not take the place of talking to your healthcare provider about your medical condition or your treatment.
Talk with your healthcare provider regularly about the use of Mircera and ask if there is new information about Mircera. What is the most important information I should know about Mircera? Mircera may cause serious side effects that can lead to death, including: For people with cancer: Mircera is not for use to treat anemia that is caused by cancer chemotherapy.
If you have certain cancers, your tumor may grow faster, and you may die sooner if you take Mircera. For people with anemia from chronic kidney disease (CKD) who take Mircera: • Serious heart problems, such as heart attack or heart failure, and stroke. You may die sooner if you are treated with Mircera to increase red blood cells (RBCs) to near the same level found in healthy people. • Blood clots.
Blood clots may happen at any time while taking Mircera. Your chance of getting a blood clot that is serious and life threatening is higher if you have cancer. If you are receiving Mircera and you are going to have surgery, talk to your healthcare provider about whether or not you need to take a blood thinner to lessen the chance of blood clots during or following surgery.
Blood clots can form in blood vessels (veins), especially in your leg (deep venous thrombosis or DVT). Pieces of a blood clot may travel to the lungs and block the blood circulation in the lungs (pulmonary embolus). Call your healthcare provider or get medical help right away if you have any of these symptoms: o Chest pain o Trouble breathing or shortness of breath o Pain in your legs, with or without swelling o A cool or pale arm or leg o Sudden confusion, trouble speaking, or trouble understanding others’ speech o Sudden numbness or weakness in your face, arm or leg, especially on one side of your body o Sudden trouble seeing o Sudden trouble walking, dizziness, loss of balance or coordination o Loss of consciousness (fainting) o Hemodialysis vascular access stops working If you and your healthcare provider decide that you should take Mircera, you should be prescribed the smallest dose of Mircera that is necessary to reduce your chance of needing RBC transfusions.
See “ What are the possible side effects of Mircera? ” below for more information. What is Mircera? Mircera is a prescription medicine used to treat anemia in certain people with chronic kidney disease (CKD).
People with anemia have a lower-than-normal number of RBCs. Mircera works like the human protein called erythropoietin to help your body make more RBCs. Mircera is used to reduce or avoid the need for RBC transfusions.
Mircera may be used to treat anemia if it is caused by CKD in: • adults who may or may not be on dialysis • children 3 months to 17 years of age who may or may not be on dialysis who are switching from another erythropoiesis-stimulating agent (ESA) after their hemoglobin level is stable If your hemoglobin level stays too high or if your hemoglobin goes up too quickly, this may lead to serious health problems which may result in death. These serious health problems may happen if you take Mircera, even if you do not have an increase in your hemoglobin level.
Mircera is not used for the treatment of anemia: • that is caused by cancer chemotherapy • in place of emergency treatment for anemia (RBC transfusions). Mircera has not been proven to improve quality of life, fatigue, or well-being. It is not known if Mircera is safe and effective in children who: • are under 3 mon…
