DOSAGE & ADMINISTRATION SECTION

LOINC: 34068-7Updated: 11/8/2023

2 DOSAGE AND ADMINISTRATION

2.1 Important Pre-Treatment Information
Discontinue administration of any iron-containing products prior to administration of INFeD.

Assess baseline hematologic (hemoglobin and hematocrit) and iron storage parameters (serum iron, total iron binding capacity, and percent saturation of transferrin) to monitor response to therapy.

Administer a test dose of INFeD prior to administration of therapeutic dose [see Dosage and Administration (2.4)].

2.2 Recommended Dosage for Iron Deficiency Anemia
Calculate the INFeD dose based upon Table 1 and formulas below. Continue INFeD until hemoglobin is within the normal range and iron stores are replete.

Administer daily doses of no more than 2 mL of INFeD until the total required dose is administered. Monitor response to therapy by evaluating hematologic parameters (hemoglobin and hematocrit) and iron storage parameters (serum iron, total iron binding capacity, and percent saturation of transferrin). Iron storage parameters may improve prior to hematologic parameters. Serum ferritin may not be an accurate measure of body iron stores in patients on chronic dialysis.

Alternatively, the total dose may be calculated using the formulas below:

Adults and Children over 15 kg (33 lbs)

Dose (mL) = 0.0442 (Desired Hb - Observed Hb) x LBW + (0.26 x LBW)

Based on:

• Desired Hb = the target hemoglobin in g/dL [Normal hemoglobin (males and females) for body weight over 15 kg (33 lbs) is 14.8 g/dL.]

• Observed Hb = the patient’s current hemoglobin in g/dL

• LBW = Lean body weight in kg [A patient’s lean body weight (or actual body weight if less than lean body weight) should be utilized when determining dosage.]
• For males: LBW = 50 kg + 2.3 kg for each inch of patient’s height over 5 feet
• For females: LBW = 45.5 kg + 2.3 kg for each inch of patient’s height over 5 feet
• To calculate a patient's weight in kg when lbs are known:

Weight in Kg

Children 5 to 15 kg (11 to 33 lbs)

Otherwise, the total dose may be calculated using the formula below:

Dose (mL) = 0.0442 (Desired Hb - Observed Hb) x W + (0.26 x W)

Based on:

• Desired Hb = the target hemoglobin in g/dL [Normal hemoglobin for children with body weight of 15 kg (33 lbs) or less is 12 g/dL.]

• W = body weight in kg
• To calculate a patient's weight in kg when lbs are known:

Weight in Kg

2.3 Recommended Dosage of Iron Replacement for Blood Loss
Calculate the INFeD dose based upon the formula below which is based upon the approximate amount of blood loss and pretreatment hematocrit.

The formula is based on the approximation that 1 mL of normocytic, normochromic red cells contains 1 mg of elemental iron.

INFeD Dose (in mL) = [Blood loss (in mL) x hematocrit] ÷ 50 mg/mL

Example: Blood loss of 500 mL with 20% hematocrit

Replacement Iron = 500 x 0.20 = 100 mg

INFeD dose volume = INFeD dose volume

2.4 Administration
The total volume of INFeD required for the treatment of iron deficiency anemia is determined from Table 1 or the appropriate formula listed [see Dosage and Administration (2.2)].

The total volume of INFeD required for the treatment of iron replacement for blood loss is determined from an appropriate formula listed [see Dosage and Administration (2.3)].

NOTE: Do not mix INFeD with other medications or add to parenteral nutrition solutions for intravenous infusion.

Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration, whenever the solution and container permit.

Discard unused portion.

Intravenous Injection

Test Dose

Prior to the first intravenous INFeD therapeutic dose, administer an intravenous test dose of 0.5 mL [see BOXED WARNING and Warnings and Precautions (5.1)]. Administer the test dose at a gradual rate over at least 30 seconds. Delay administration of the initial therapeutic INFeD dose until 1 hour or more after the test dose. If a hypersensitivity reaction occurs with the test dose, manage medically and do not administer further doses of INFeD.

INFeD is given undiluted at a slow gradual rate not to exceed 50 mg (1 mL) per minute.

The maximum daily dose of INFeD should not exceed 2 mL.

Intramuscular Injection

Test Dose

Prior to the first intramuscular INFeD therapeutic dose, administer an intramuscular test dose of 0.5 mL [see BOXED WARNING and Warnings and Precautions (5.1)]. Administer the test dose at a gradual rate over at least 30 seconds into the buttock. Delay administration of the initial therapeutic INFeD dose until 1 hour or more after the test dose. If a hypersensitivity reaction occurs with the test dose, manage medically and do not administer further doses of INFeD.

If no adverse reactions are observed, INFeD can be given according to the following schedule until the calculated total required dose has been reached. Each day’s dose should not exceed 0.5 mL (25 mg of iron) for infants with body weight under 5 kg (11 lbs); 1 mL (50 mg of iron) for children with body weight under 10 kg (22 lbs); and 2 mL (100 mg of iron) for other patients.

The maximum daily dose of INFeD should not exceed 2 mL.

INFeD should be injected only into the muscle mass of the upper outer quadrant of the buttock - never into the arm or other exposed areas - and should be injected deeply, with a 2-inch or 3-inch 19 or 20 gauge needle. If the patient is standing, he/she should be bearing his/her weight on the leg opposite the injection site, or if in bed, he/she should be in the lateral position with injection site uppermost. To avoid injection or leakage into the subcutaneous tissue, a Z-track technique (displacement of the skin laterally prior to injection) is recommended.

PATIENT COUNSELING INFORMATION

LOINC: 88436-1Updated: 10/20/2022

17 PATIENT COUNSELING

Hypersensitivity Reactions
Question patients regarding any prior history of reactions to parenteral iron products. Advise patients to immediately report any symptoms of hypersensitivity that develop during and following INFeD administration such as arthralgia, backache, chills, dizziness, moderate to high fever, headache, malaise, myalgia, nausea, and vomiting [see Warnings and Precautions (5.1)].

Delayed Reactions
Advise patients that delayed reactions can occur and that these must be reported to their healthcare provider immediately [see Warnings and Precautions (5.2)].

Increased Risk of Toxicity in Patients with Underlying Conditions
Advise patients to inform their healthcare provider if any liver impairment is identified as this may cause iron toxicity. Advise patients to consult their healthcare provider should they start to show symptoms of acute kidney infection as INFeD should not be used [see Warnings and Precautions (5.3)].

Advise patients with pre-existing cardiovascular disease and rheumatoid arthritis that INFeD administration may exacerbate symptoms and to contact their healthcare provider if any symptoms occur [see Warnings and Precautions (5.3)].

Advise patients with history of significant allergies and/or asthma to inform their healthcare provider as the risk of hypersensitivity reactions may be increased [see Warnings and Precautions (5.3)].

Iron Overload
Advise the patient to consult a healthcare provider before taking any other iron containing products as this may cause serious side effects [see Warnings and Precautions (5.4)].

Pregnancy
Advise pregnant persons about the risk of hypersensitivity reactions which may have serious consequences for the fetus [see Use in Specific Populations (8.1)].
