Drug interactions
Moderate drug interactions
Moderate:
iron polysaccharide cefdinir
Applies to: Polysaccharide Iron (iron polysaccharide) and cefdinir
Cefdinir and iron polysaccharide should not be taken orally at the same time.
Products that contain iron may interfere with the absorption of cefdinir and reduce its effectiveness.
You should take cefdinir either 2 hours before or 2 hours after the iron polysaccharide dose.
Contact your doctor if you have reddish stools (which may indicate occurrence of the interaction) or your infection worsens.
It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Food/lifestyle interactions
Moderate food/lifestyle interactions
Moderate:
iron polysaccharide Food/Lifestyle
Applies to: Polysaccharide Iron (iron polysaccharide)
Food may reduce the absorption and blood levels of iron polysaccharide. In addition, some oral medications can also interfere with iron polysaccharide absorption into the bloodstream, which may make the medication less effective in treating your condition. Likewise, iron polysaccharide may interfere with the absorption of other orally administered medications.
You should take iron polysaccharide on an empty stomach at least one hour before or two hours after a meal.
Your doctor may be able to prescribe alternatives that do not interact, or you may need a dose adjustment or more frequent monitoring to safely use both medications.
Talk to your doctor or pharmacist if you have questions about how to take this or other medications you are prescribed. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
Disease interactions
12 potential interactions Applies to: 10 conditions, including Seizures, Peptic Ulcer, Diabetes Mellitus, Hemodialysis, and Liver Disease.
Achlorhydria
Moderate:
Polysaccharide Iron
The iron polysaccharide in Polysaccharide Iron has a moderate potential interaction with Achlorhydria.
Gastric acidity increases iron bioavailability by maintaining the ingested iron in a reduced form as ferrous ions, which are more readily absorbed than ferric ions. Therefore, when iron therapy is administered orally, higher dosages may be necessary for patients with decreased gastric acid production. Also, a liquid formulation is recommended in these patients because dissolution of the tablet coating depends on normal gastric acidity.
Blood Transfusion
Major:
Polysaccharide Iron
The iron polysaccharide in Polysaccharide Iron has a major potential interaction with Blood Transfusion.
There is no excretory mechanism for iron. Iron will correct only hemoglobin abnormalities due to iron deficiency and should not be used to treat conditions such as thalassemia, hemosiderosis, hemochromatosis, normocytic anemia (unless iron deficiency exists), or in patients receiving blood transfusions. Clinical monitoring of erythropoietic function and ferritin levels is recommended.
Diabetes Mellitus
Moderate:
cefdinir
Cefdinir has a moderate potential interaction with Diabetes Mellitus.
Omnicef (brand of cefdinir) oral suspension contains 2.86 grams of sucrose per each 5 mL of reconstituted suspension. The sugar content should be considered when this product is used in patients with diabetes.
Moderate:
cefdinir
Cefdinir has a moderate potential interaction with Diabetes Mellitus.
The cephalosporins, cefixime and cefdinir, have been reported to cause false-positive reactions for ketones in the urine with tests using nitroprusside, but not with tests using nitroferricyanide. Clinicians should be cognizant of this interaction when prescribing or administering either of these agents to patients with diabetes.
Hemodialysis
Moderate:
cefdinir
Cefdinir has a moderate potential interaction with Hemodialysis.
Most cephalosporin antibiotics are removed by hemodialysis. Doses should either be scheduled for administration after dialysis or supplemental doses be given after dialysis. Cefonicid, cefixime, and ceftriaxone are not significantly removed by hemodialysis.
Hemoglobinopathy
Major:
Polysaccharide Iron
The iron polysaccharide in Polysaccharide Iron has a major potential interaction with Hemoglobinopathy.
There is no excretory mechanism for iron. Iron will correct only hemoglobin abnormalities due to iron deficiency and should not be used to treat conditions such as thalassemia, hemosiderosis, hemochromatosis, normocytic anemia (unless iron deficiency exists), or in patients receiving blood transfusions. Clinical monitoring of erythropoietic function and ferritin levels is recommended.
Liver Disease
Moderate:
cefdinir
Cefdinir has a moderate potential interaction with Liver Disease.
Cases of hepatitis have been reported with the use of certain cephalosporins. Transient rise in AST, ALT, and alkaline phosphatase levels have also been observed. Caution and monitoring are recommended when these agents are prescribed to patients with hepatic disorders.
Noninfectious Colitis
Major:
cefdinir
Cefdinir has a major potential interaction with Noninfectious Colitis.
Clostridioides difficile-associated diarrhea (CDAD), formerly pseudomembranous colitis, has been reported with almost all antibacterial drugs and may range from mild diarrhea to fatal colitis. The most common culprits include clindamycin and lincomycin. Antibacterial therapy alters the normal flora of the colon, leading to overgrowth of C difficile, whose toxins A and B contribute to CDAD development. Morbidity and mortality are increased with hypertoxin-producing strains of C difficile; these infections can be resistant to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea after antibacterial use. Since CDAD has been reported to occur more than 2 months after antibacterial use, careful medical history is necessary. Therapy with broad-spectrum antibacterials and other agents with significant antibacterial activity should be administered cautiously in patients with history of gastrointestinal disease, particularly colitis; pseudomembranous colitis (generally characterized by severe, persistent diarrhea and severe abdominal cramps, and sometimes associated with the passage of blood and mucus), if it occurs, may be more severe in these patients and may be associated with flares in underlying disease activity. Antibacterial drugs not directed against C difficile may need to be stopped if CDAD is suspected or confirmed. Appropriate fluid and electrolyte management, protein supplementation, antibacterial treatment of C difficile, and surgical evaluation should be started as clinically indicated.
Moderate:
Polysaccharide Iron
The iron polysaccharide in Polysaccharide Iron has a moderate potential interaction with Noninfectious Colitis.
Iron can be irritating and damaging to gastrointestinal mucosa. Iron therapy should be administered cautiously in patients with peptic ulcer disease, enteritis, or ulcerative colitis.
Peptic Ulcer
Moderate:
Polysaccharide Iron
The iron polysaccharide in Polysaccharide Iron has a moderate potential interaction with Peptic Ulcer.
Iron can be irritating and damaging to gastrointestinal mucosa. Iron therapy should be administered cautiously in patients with peptic ulcer disease, enteritis, or ulcerative colitis.
Renal Dysfunction
Moderate:
cefdinir
Cefdinir has a moderate potential interaction with Renal Dysfunction.
Most beta-lactam antibiotics are eliminated by the kidney as unchanged drug and, in some cases, also as metabolites. The serum concentrations of beta-lactam antibiotics and their metabolites may be increased and the half-lives prolonged in patients with impaired renal function. Dosage adjustments may be necessary and modifications should be based on the degree of renal impairment as well as severity of infection in accordance with the individual product package labeling. Renal function tests should be performed periodically during prolonged and/or high-dose therapy, since nephrotoxicity and alterations in renal function have occasionally been associated with the use of these drugs.
Seizures
Moderate:
cefdinir
Cefdinir has a moderate potential interaction with Seizures.
Cephalosporins have been implicated in triggering seizures. Nonconvulsive status epilepticus, encephalopathy, coma, asterixis, neuromuscular excitability, and myoclonia have been reported with cephalosporins, particularly in patients with a history of epilepsy and/or when recommended dosages of cephalosporins were exceeded due to renal dysfunction. Dosage should be adjusted based on the degree of renal function. Anticonvulsant therapy should be continued in patients with known seizure disorders. If CNS adverse reactions including seizures occur, patients should undergo a neurological evaluation to determine whether treatment should be discontinued.
