ferric citrate

(fe-rik si-trate)


Therapeutic: electrolyte modifiers
Pharmacologic: phosphate binders
Pregnancy Category: B


Control of serum phosphorous in chronic renal failure patients on dialysis.


Binds phosphorous and precipitates it as ferric phosphate.

Therapeutic effects

Maintenance of normal phosphorous levels.


Absorption: Some absorption follows oral administration and may lead to iron overload.
Distribution: Unknown.
Metabolism and Excretion: Following binding, precipitated ferric phosphate is excreted in stool.
Half-life: Unknown.

Time/action profile (lowering of serum phosphorous)

POwithin 1 wkunknownunknown


Contraindicated in: Iron overload syndromes including hemochromatosis).
Use Cautiously in: GI bleeding/inflammation; Obstetric: Use cautiously during pregnancy (consider effects on vitamins/nutrient and potential iron overload); Lactation: Consider possible iron transport into milk; Pediatric: Safe and effective use in children has not been established.

Adverse Reactions/Side Effects


  • diarrhea (most frequent)
  • discolored feces (most frequent)
  • nausea (most frequent)
  • constipation
  • vomiting


  • iron overload


Drug-Drug interaction

Will bind and ↓ absorption of doxycycline (should be given one hr prior to ferric citrate).


Oral (Adults) 2 tablets (2 g ferric citrate) three times daily. Adjust by 1–2 tablets/day at weekly (or longer) intervals to attain target phosphorous levels.


Tablets: 1 g (contains 210 mg ferric iron)

Nursing implications

Nursing assessment

  • Monitor clinical responses or blood levels of concurrent medications; may decrease bioavailability of medications administered concurrently.
  • Lab Test Considerations: Monitor serum phosphorous prior to starting and periodically during therapy to keep serum phosphorous at target levels.
    • Assess iron parameters (serum ferritin and transferritin saturation TSAT) prior to starting and periodically during therapy. May cause ↑ serum ferritin and TSAT requiring reduced dose or discontinuation of IV iron therapy.

Potential Nursing Diagnoses

Deficient knowledge, related to medication regimen (Patient/Family Teaching)


  • Oral: Administer 3 times daily with meals.

Patient/Family Teaching

  • Instruct patient to take ferric citrate as directed and to continue with prescribed diet.
  • Advise patient that ferric citrate may cause dark stools; this is normal for medications containing iron.
  • Inform patient that ferric citrate may cause diarrhea, nausea, constipation, and vomiting. Notify health care professional if GI symptoms become severe or persistent.
  • Advise patient to notify health care professional of all Rx or OTC medications, vitamins, or herbal products being taken and to consult with health care professional before taking other medications. Medications may need to be taken separately from ferric citrate.
  • Advise female patient to notify health care professional if pregnancy is planned or suspected or if breastfeeding.

Evaluation/Desired Outcomes

  • Normal serum phosphorous levels.
