Inactive ingredient FAQ

Are inactive ingredients the same for every manufacturer?
No. Inactive ingredients can differ by manufacturer, dosage form, strength, and package / product version.
Why might an inactive ingredient be missing?
Some SPLs do not provide a complete structured inactive-ingredient list, and older or unusual labels may only include the information in narrative text.
Can inactive ingredients matter?
Yes. They can matter for allergies, intolerances, dyes, gluten / lactose concerns, preservatives, and formulation differences — but confirm with a pharmacist or the manufacturer when it’s clinically important.

Where does this data come from?
NADAC (National Average Drug Acquisition Cost) is the CMS weekly pharmacy-acquisition-cost survey — what pharmacies pay. ASP (Average Sales Price) is the CMS Medicare Part B drug-payment file, published quarterly. Medicaid pays is computed by us from CMS State Drug Utilization Data (total reimbursed ÷ units, trailing 12 months) — gross of rebates and inclusive of dispensing fees, so it reflects what Medicaid paid, not an acquisition cost. Medicare drug plans pay is the median negotiated point-of-sale unit cost across plans listing this NDC in the CMS quarterly Prescription Drug Plan pricing files, before rebates. The VA pays is the federal contract price (FSS, and the statutory Big 4 ceiling where listed) from the VA National Acquisition Center pharmaceutical price file. All are free public government data; each measures a different payer, so the figures are not directly comparable.

⚠️ Warnings and Cautions ~1 min read

5 WARNINGS AND PRECAUTIONS Iron overload: Monitor ferritin and TSAT. Patients may require a reduction in dose or discontinuation of intravenous iron. ( 5.1 ) Accidental overdose of iron-containing products is a leading cause of fatal poisoning in children under 6 years of age. Keep this product out of reach of children. In case of accidental overdose, call a doctor or poison control center immediately. ( 5.2 )

5.1Iron Overload Iron absorption from ferric citrate may lead to excessive elevations in iron stores. Increases in serum ferritin and transferrin saturation (TSAT) levels were observed in clinical trials. In a 56-week safety and efficacy trial evaluating the control of serum phosphate levels in patients with chronic kidney disease on dialysis in which concomitant use of intravenous iron was permitted, 55 (19%) of patients treated with ferric citrate had a ferritin level >1500 ng/mL as compared with 13 (9%) of patients treated with active control.

Assess iron parameters (e.g., serum ferritin and TSAT) prior to initiating ferric citrate and monitor iron parameters while on therapy [see Contraindications (4), Overdosage (10) and Clinical Pharmacology (12.2)] . Patients receiving intravenous iron may require a reduction in dose or discontinuation of intravenous iron therapy.

5.2Risk of Overdosage in Children Due to Accidental Ingestion Accidental ingestion and resulting overdose of iron-containing products is a leading cause of fatal poisoning in children under 6 years of age [see Overdosage (10)] . Advise patients of the risks to children and to keep ferric citrate tablets out of the reach of children.

🤒 Adverse Reactions ~2 min read

6 ADVERSE REACTIONS Most common adverse reactions (incidence ≥5%) are discolored feces, diarrhea, constipation, nausea, vomiting, cough, abdominal pain, and hyperkalemia. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Teva at 1-888-838-2872 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

6.1Clinical 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 adverse reaction rates in the clinical trials of another drug and may not reflect the rates observed in practice. Hyperphosphatemia in Chronic Kidney Disease on Dialysis A total of 289 patients were treated with ferric citrate and 149 patients were treated with active control (sevelamer carbonate and/or calcium acetate) during the 52-week, randomized, open-label, active control phase of a trial in patients on dialysis.

A total of 322 patients were treated with ferric citrate for up to 28 days in three short-term trials. Across these trials, 557 unique patients were treated with ferric citrate; dosage regimens in these trials ranged from 210 mg to 2,520 mg of ferric iron per day, equivalent to 1 to 12 tablets of ferric citrate. Adverse reactions reported in more than 5% of patients treated with ferric citrate in these trials included diarrhea (21%), discolored feces (19%), nausea (11%), constipation (8%), vomiting (7%), and cough (6%).

During the 52-week, active-control period, 61 patients (21%) on ferric citrate discontinued study drug because of an adverse reaction, as compared to 21 patients (14%) in the active control arm. Patients who were previously intolerant to any of the active control treatments (calcium acetate and sevelamer carbonate) were not eligible to enroll in the study. Gastrointestinal adverse reactions were the most common reason for discontinuing ferric citrate (14%).

Iron Deficiency Anemia in Chronic Kidney Disease Not on Dialysis Across two trials, 190 patients with CKD-NDD were treated with ferric citrate. This included a study of 117 patients treated with ferric citrate and 116 patients treated with placebo in a 16-week, randomized, double-blind period and a study of 75 patients treated with ferric citrate and 73 treated with placebo in a 12-week randomized double-blind period. Dosage regimens in these trials ranged from 210 mg to 2,520 mg of ferric iron per day, equivalent to 1 to 12 tablets of ferric citrate.

Adverse reactions reported in at least 5% of patients treated with ferric citrate in these trials are listed in Table 1. Table 1: Adverse Reactions Reported in Two Clinical Trials in at least 5% of patients receiving Ferric Citrate Body System Adverse Reaction Ferric Citrate % (N=190) Placebo % (N=188) Any Adverse Reaction 75 62 Metabolism and Nutrition Disorders Hyperkalemia 5 3 Gastrointestinal Disorders Discolored Feces 22 0 Diarrhea 21 12 Constipation 18 10 Nausea 10 4 Abdominal Pain 5 2 During the 16-week, placebo-control trial, 12 patients (10%) on ferric citrate discontinued study drug because of an adverse reaction, as compared to 10 patients (9%) in the placebo control arm.

Diarrhea was the most common adverse reaction leading to discontinuation of ferric citrate (2.6%).

🔄 Drug Interactions 206 words

7 DRUG INTERACTIONS Table 2: Oral drugs that can be administered concomitantly with ferric citrate Amlodipine Aspirin Atorvastatin Calcitriol Clopidogrel Digoxin Diltiazem Doxercalciferol Enalapril Fluvastatin Glimepiride Levofloxacin Losartan Metoprolol Pravastatin Propranolol Sitagliptin Warfarin Oral drugs that have to be separated from ferric citrate and meals Dosing Recommendations Doxycycline Take at least 1 hour before ferric citrate Ciprofloxacin Take at least 2 hours before or after ferric citrate Oral medications not listed in Table 2.

There are no empirical data on avoiding drug interactions between ferric citrate and most concomitant oral drugs. For oral medications where a reduction in the bioavailability of that medication would have a clinically significant effect on its safety or efficacy, consider separation of the timing of the administration of the two drugs. The duration of separation depends upon the absorption characteristics of the medication concomitantly administered, such as the time to reach peak systemic levels and whether the drug is an immediate release or an extended release product.

Consider monitoring clinical responses or blood levels of concomitant medications that have a narrow therapeutic range. When clinically significant drug interactions are expected, consider separation of the timing of administration. Consider monitoring clinical responses or blood levels of the concomitant medication.

👥 Use in Specific Populations ~2 min read

8 USE IN SPECIFIC POPULATIONS

8.1Pregnancy Risk Summary There are no available data on ferric citrate use in pregnant women to inform a drug-associated risk of major birth defects and miscarriage. Animal reproduction studies have not been conducted using ferric citrate. Skeletal and encephalic malformation was observed in neonatal mice when ferric gluconate was administered intraperitoneally to gravid dams on gestation days 7 to 9.

However, oral administration of other ferric or ferrous compounds to gravid CD1-mice and Wistar-rats caused no fetal malformation. An overdose of iron in pregnant women may carry a risk for spontaneous abortion, gestational diabetes and fetal malformation. The estimated background risk of major birth defects and miscarriage for the indicated population is unknown.

Adverse outcomes in pregnancy occur regardless of the health of the mother or the use of medications. In the U.S. general population, the estimated background risks of major birth defects and miscarriage in clinically recognized pregnancies are 2% to 4% and 15% to 20%, respectively. Clinical Considerations The effect of ferric citrate on the absorption of vitamins and other nutrients has not been studied in pregnant women.

Requirements for vitamins and other nutrients are increased in pregnancy.

8.2Lactation Risk Summary There are no human data regarding the effect of ferric citrate in human milk, the effects on the breastfed child, or the effects on milk production. Data from rat studies have shown the transfer of iron into milk by divalent metal transporter-1 (DMT-1) and ferroportin-1 (FPN-1). Hence, there is a possibility of infant exposure when ferric citrate is administered to a nursing woman.

The development and health benefits of breastfeeding should be considered along with the mother’s clinical need for ferric citrate and any potential adverse effects on the breastfed child from ferric citrate or from the underlying maternal condition.

8.4Pediatric Use The safety and efficacy of ferric citrate has not been established in pediatric patients. Juvenile Animal Toxicity Data In animal studies, greater gastrointestinal toxicity was observed when ferric citrate was administered by gavage as compared to administration with solid food. Because ferric citrate is recommended to be taken with meals and patients under 6 months of age are unlikely to be eating solid food, they may be at greater risk of gastrointestinal toxicity.

8.5Geriatric Use Clinical studies of ferric citrate included 292 subjects aged 65 years and older (104 subjects aged 75 years and older). Overall, the clinical study experience has not identified any obvious differences in responses between the elderly and younger patients in the tolerability or efficacy of ferric citrate.

🆘 Overdosage 89 words

10 OVERDOSAGE No data are available regarding overdose of ferric citrate in patients. In patients with chronic kidney disease, the maximum dose studied was 2,520 mg ferric iron (12 tablets of ferric citrate) per day. Iron absorption from ferric citrate may lead to excessive elevations in iron stores, especially when concomitant intravenous iron is used [see Warnings and Precautions (5.1)] .

In clinical trials, one case of elevated iron in the liver as confirmed by biopsy was reported in a patient on dialysis administered intravenous iron and ferric citrate.

🧬 Clinical Pharmacology ~2 min read

12 CLINICAL PHARMACOLOGY

12.1Mechanism of Action Hyperphosphatemia in Chronic Kidney Disease on Dialysis Ferric iron binds dietary phosphate in the GI tract and precipitates as ferric phosphate. This compound is insoluble and is excreted in the stool. By binding phosphate in the GI tract and decreasing absorption, ferric citrate lowers the phosphate concentration in the serum.

Iron Deficiency Anemia in Chronic Kidney Disease Not on Dialysis Ferric iron is reduced from the ferric to the ferrous form by ferric reductase in the GI tract. After transport through the enterocytes into the blood, oxidized ferric iron circulates bound to the plasma protein transferrin, and can be incorporated into hemoglobin.

12.2Pharmacodynamics Hyperphosphatemia in Chronic Kidney Disease on Dialysis Ferric citrate reduces serum phosphorus levels and has also been shown to increase serum iron parameters, including ferritin, iron and TSAT. In dialysis patients treated with ferric citrate for hyperphosphatemia in a 52-week study in which intravenous iron could also be administered, mean (SD) ferritin levels rose from 593 (293) ng/mL to 895 (482) ng/mL, mean (SD) TSAT levels rose from 31% (11) to 39% (17) and mean (SD) iron levels rose from 73 (29) mcg/dL to 88 (42) mcg/dL.

In contrast, in patients treated with active control, these parameters remained relatively constant [see Contraindications (4) and Warnings and Precautions (5.1)] . Iron Deficiency Anemia in Chronic Kidney Disease Not on Dialysis Ferric citrate may increase hemoglobin levels and has also been shown to reduce serum phosphorus levels. In chronic kidney disease patients not on dialysis treated with ferric citrate for iron deficiency anemia in a 16-week placebo-controlled study, mean (SD) phosphorus levels decreased from 4.23 (0.91) mg/dL at baseline to 3.72 (0.60) mg/dL.

In comparison, in patients treated with placebo control, mean (SD) phosphorus levels decreased from 4.12 (0.68) mg/dL at baseline to 3.87 (0.68) mg/dL.

12.3Pharmacokinetics Absorption and Distribution Formal pharmacokinetic studies have not been performed with ferric citrate. Examination of serum iron parameters has shown that there is systemic absorption of iron from ferric citrate [see Contraindications (4), Warnings and Precautions (5.1) and Clinical Pharmacology (12.1)] . Drug Interaction Studies In vitro Of the drugs screened for an interaction with ferric citrate in vitro, only doxycycline showed the potential for interaction with at least 70% decrease in its concentration.

This interaction can be avoided by spacing the administration of doxycycline and ferric citrate [see Drug Interactions (7)] . In vivo Six drug interaction studies (N=26 to 60/study) were conducted to establish the effects of ferric citrate (administered as 3 x 2 g/day with meals) on the disposition of concomitantly orally administered clopidogrel, ciprofloxacin, digoxin, diltiazem, glimepiride and losartan in healthy subjects. With the exception of ciprofloxacin, ferric citrate did not alter the systemic exposure of the tested drugs, as measured by the area under the curve (AUC) and C max of the tested drugs when either co-administered with ferric citrate or given 2 hours later.

Ferric citrate decreased the relative bioavailability of concomitantly administered ciprofloxacin by approximately 45%. However, there was no interaction when ferric citrate and ciprofloxacin were taken 2 hours apart. Consequently, ciprofloxacin should be taken at least 2 hours before or after ferric citrate is dosed [see Drug Interactions (7)] .
