🎯 Indications and Usage ▾
INDICATIONS AND USAGE To reduce the development of drug-resistant bacteria and maintain the effectiveness of cefdinir and other antibacterial drugs, cefdinir should be used only to treat or prevent infections that are proven or strongly suspected to be caused by susceptible bacteria. When culture and susceptibility information are available, they should be considered in selecting or modifying antibacterial therapy. In the absence of such data, local epidemiology and susceptibility patterns may contribute to the empiric selection of therapy.
Cefdinir capsules, USP are indicated for the treatment of patients with mild to moderate infections caused by susceptible strains of the designated microorganisms in the conditions listed below. Adults and Adolescents Community-Acquired Pneumonia caused by Haemophilus influenzae (including β-lactamase producing strains), Haemophilus parainfluenzae (including β-lactamase producing strains), Streptococcus pneumoniae (penicillin-susceptible strains only), and Moraxella catarrhalis (including β-lactamase producing strains) (see CLINICAL STUDIES ).
Acute Exacerbations of Chronic Bronchitis caused by Haemophilus influenzae (including β-lactamase producing strains), Haemophilus parainfluenzae (including β-lactamase producing strains), Streptococcus pneumoniae (penicillin-susceptible strains only), and Moraxella catarrhalis (including β-lactamase producing strains). Acute Maxillary Sinusitis caused by Haemophilus influenzae (including β-lactamase producing strains), Streptococcus pneumoniae (penicillin-susceptible strains only), and Moraxella catarrhalis (including β-lactamase producing strains).
NOTE: For information on use in pediatric patients, see Pediatric Use and DOSAGE AND ADMINISTRATION . Pharyngitis/Tonsillitis caused by Streptococcus pyogenes (see CLINICAL STUDIES ). NOTE: Cefdinir is effective in the eradication of S. pyogenes from the oropharynx.
Cefdinir has not, however, been studied for the prevention of rheumatic fever following S. pyogenes pharyngitis/tonsillitis. Only intramuscular penicillin has been demonstrated to be effective for the prevention of rheumatic fever. Uncomplicated Skin and Skin Structure Infections caused by Staphylococcus aureus (including β-lactamase producing strains) and Streptococcus pyogenes .
Pediatric Patients Acute Bacterial Otitis Media caused by Haemophilus influenzae (including β-lactamase producing strains), Streptococcus pneumoniae (penicillin-susceptible strains only), and Moraxella catarrhalis (including β-lactamase producing strains). Pharyngitis/Tonsillitis caused by Streptococcus pyogenes (see CLINICAL STUDIES ). NOTE: Cefdinir is effective in the eradication of S. pyogenes from the oropharynx.
Cefdinir has not, however, been studied for the prevention of rheumatic fever following S. pyogenes pharyngitis/tonsillitis. Only intramuscular penicillin has been demonstrated to be effective for the prevention of rheumatic fever. Uncomplicated Skin and Skin Structure Infections caused by Staphylococcus aureus (including β-lactamase producing strains) and Streptococcus pyogenes .
⏱️ Dosage and Administration ▾
DOSAGE AND ADMINISTRATION (see INDICATIONS AND USAGE for Indicated Pathogens) The recommended dosage and duration of treatment for infections in adults and adolescents are described in the following chart; the total daily dose for all infections is 600 mg. Once-daily dosing for 10 days is as effective as BID dosing. Once-daily dosing has not been studied in pneumonia or skin infections; therefore, cefdinir capsules should be administered twice daily in these infections.
Cefdinir capsules may be taken without regard to meals. Adults and Adolescents (Age 13 Years and Older) Type of Infection Dosage Duration Community-Acquired Pneumonia 300 mg q12h 10 days Acute Exacerbations of Chronic Bronchitis 300 mg q12h or 600 mg q24h 5 to 10 days 10 days Acute Maxillary Sinusitis 300 mg q12h or 600 mg q24h 10 days 10 days Pharyngitis/Tonsillitis 300 mg q12h or 600 mg q24h 5 to 10 days 10 days Uncomplicated Skin and Skin Structure Infections 300 mg q12h 10 days Patients With Renal Insufficiency For adult patients with creatinine clearance <30 mL/min, the dose of cefdinir should be 300 mg given once daily.
Creatinine clearance is difficult to measure in outpatients. However, the following formula may be used to estimate creatinine clearance (CL cr ) in adult patients. For estimates to be valid, serum creatinine levels should reflect steady-state levels of renal function.
Males: CL cr = (weight) (140 – age) (72) (serum creatinine) Females: CL cr = 0.85 x above value where creatinine clearance is in mL/min, age is in years, weight is in kilograms, and serum creatinine is in mg/dL. 1 The following formula may be used to estimate creatinine clearance in pediatric patients: CL cr = K x body length or height serum creatinine where K=0.55 for pediatric patients older than 1 year 2 and 0.45 for infants (up to 1 year) 3 . In the above equation, creatinine clearance is in mL/min/1.73 m 2 , body length or height is in centimeters, and serum creatinine is in mg/dL.
For pediatric patients with a creatinine clearance of <30 mL/min/1.73 m 2 , the dose of cefdinir should be 7 mg/kg (up to 300 mg) given once daily. Patients on Hemodialysis Hemodialysis removes cefdinir from the body. In patients maintained on chronic hemodialysis, the recommended initial dosage regimen is a 300 mg or 7 mg/kg dose every other day.
At the conclusion of each hemodialysis session, 300 mg (or 7 mg/kg) should be given. Subsequent doses (300 mg or 7 mg/kg) are then administered every other day.
⛔ Contraindications ▾
CONTRAINDICATIONS Cefdinir capsules are contraindicated in patients with known allergy to the cephalosporin class of antibiotics.
⚠️ Warnings ▾
WARNINGS BEFORE THERAPY WITH CEFDINIR IS INSTITUTED, CAREFUL INQUIRY SHOULD BE MADE TO DETERMINE WHETHER THE PATIENT HAS HAD PREVIOUS HYPERSENSITIVITY REACTIONS TO CEFDINIR, OTHER CEPHALOSPORINS, PENICILLINS, OR OTHER DRUGS. IF CEFDINIR IS TO BE GIVEN TO PENICILLIN-SENSITIVE PATIENTS, CAUTION SHOULD BE EXERCISED BECAUSE CROSS-HYPERSENSITIVITY AMONG β-LACTAM ANTIBIOTICS HAS BEEN CLEARLY DOCUMENTED AND MAY OCCUR IN UP TO 10% OF PATIENTS WITH A HISTORY OF PENICILLIN ALLERGY. IF AN ALLERGIC REACTION TO CEFDINIR OCCURS, THE DRUG SHOULD BE DISCONTINUED.
SERIOUS ACUTE HYPERSENSITIVITY REACTIONS MAY REQUIRE TREATMENT WITH EPINEPHRINE AND OTHER EMERGENCY MEASURES, INCLUDING OXYGEN, INTRAVENOUS FLUIDS, INTRAVENOUS ANTIHISTAMINES, CORTICOSTEROIDS, PRESSOR AMINES, AND AIRWAY MANAGEMENT, AS CLINICALLY INDICATED. Clostridium difficile associated diarrhea (CDAD) has been reported with use of nearly all antibacterial agents, including cefdinir, and may range in severity from mild diarrhea to fatal colitis. Treatment with antibacterial agents alters the normal flora of the colon leading to overgrowth of C. difficile .
C. difficile produces toxins A and B which contribute to the development of CDAD. Hypertoxin producing strains of C. difficile cause increased morbidity and mortality, as these infections can be refractory to antimicrobial therapy and may require colectomy. CDAD must be considered in all patients who present with diarrhea following antibacterial use.
Careful medical history is necessary since CDAD has been reported to occur over two months after the administration of antibacterial agents. If CDAD is suspected or confirmed, ongoing antibacterial use not directed against C . difficile may need to be discontinued. Appropriate fluid and electrolyte management, protein supplementation, antibacterial treatment of C. difficile , and surgical evaluation should be instituted as clinically indicated.
🤒 Adverse Reactions ▾
ADVERSE EVENTS Clinical Trials - Cefdinir Capsules (Adult and Adolescent Patients) In clinical trials, 5093 adult and adolescent patients (3841 U.S. and 1252 non-U.S.) were treated with the recommended dose of cefdinir capsules (600 mg/day). Most adverse events were mild and self-limiting. No deaths or permanent disabilities were attributed to cefdinir.
One hundred forty-seven of 5093 (3%) patients discontinued medication due to adverse events thought by the investigators to be possibly, probably, or definitely associated with cefdinir therapy. The discontinuations were primarily for gastrointestinal disturbances, usually diarrhea or nausea. Nineteen of 5093 (0.4%) patients were discontinued due to rash thought related to cefdinir administration.
In the U.S., the following adverse events were thought by investigators to be possibly, probably, or definitely related to cefdinir capsules in multiple-dose clinical trials (N = 3841 cefdinir-treated patients): ADVERSE EVENTS ASSOCIATED WITH CEFDINIR CAPSULES U.S. TRIALS IN ADULT AND ADOLESCENT PATIENTS (N = 3841) a a 1733 males, 2108 females Incidence ≥1% Diarrhea 15% Vaginal moniliasis 4% of women Nausea 3% Headache 2% Abdominal pain 1% Vaginitis 1% of women Incidence <1% but >0.1% Rash 0.9% Dyspepsia 0.7% Flatulence 0.7% Vomiting 0.7% Abnormal stools 0.3% Anorexia 0.3% Constipation 0.3% Dizziness 0.3% Dry mouth 0.3% Asthenia 0.2% Insomnia 0.2% Leukorrhea 0.2% of women Moniliasis 0.2% Pruritus 0.2% Somnolence 0.2% The following laboratory value changes of possible clinical significance, irrespective of relationship to therapy with cefdinir, were seen during clinical trials conducted in the U.S.: LABORATORY VALUE CHANGES OBSERVED WITH CEFDINIR CAPSULES U.S.

🔄 Drug Interactions ▾
Drug Interactions Antacids (aluminum- or magnesium-containing) Concomitant administration of 300 mg cefdinir capsules with 30 mL Maalox ® TC suspension reduces the rate (C max ) and extent (AUC) of absorption by approximately 40%. Time to reach C max is also prolonged by 1 hour. There are no significant effects on cefdinir pharmacokinetics if the antacid is administered 2 hours before or 2 hours after cefdinir.
If antacids are required during cefdinir therapy, cefdinir should be taken at least 2 hours before or after the antacid. Probenecid As with other β-lactam antibiotics, probenecid inhibits the renal excretion of cefdinir, resulting in an approximate doubling in AUC, a 54% increase in peak cefdinir plasma levels, and a 50% prolongation in the apparent elimination t ½ . Iron Supplements and Foods Fortified With Iron Concomitant administration of cefdinir with a therapeutic iron supplement containing 60 mg of elemental iron (as FeSO 4 ) or vitamins supplemented with 10 mg of elemental iron reduced extent of absorption by 80% and 31%, respectively.
If iron supplements are required during cefdinir therapy, cefdinir should be taken at least 2 hours before or after the supplement. The effect of foods highly fortified with elemental iron (primarily iron-fortified breakfast cereals) on cefdinir absorption has not been studied. Concomitantly administered iron-fortified infant formula (2.2 mg elemental iron/6 oz) has no significant effect on cefdinir pharmacokinetics.
There have been reports of reddish stools in patients receiving cefdinir. In many cases, patients were also receiving iron-containing products. The reddish color is due to the formation of a nonabsorbable complex between cefdinir or its breakdown products and iron in the gastrointestinal tract.
🔄 Drug / Laboratory Test Interactions ▾
Drug/Laboratory Test Interactions A false-positive reaction for ketones in the urine may occur with tests using nitroprusside, but not with those using nitroferricyanide. The administration of cefdinir may result in a false-positive reaction for glucose in urine using Clinitest ® , Benedict’s solution, or Fehling’s solution. It is recommended that glucose tests based on enzymatic glucose oxidase reactions (such as Clinistix ® or Tes-Tape ® ) be used.
Cephalosporins are known to occasionally induce a positive direct Coombs’ test.
🤰 Pregnancy ▾
Pregnancy Teratogenic Effects Pregnancy Category B Cefdinir was not teratogenic in rats at oral doses up to 1000 mg/kg/day (70 times the human dose based on mg/kg/day, 11 times based on mg/m 2 /day) or in rabbits at oral doses up to 10 mg/kg/day (0.7 times the human dose based on mg/kg/day, 0.23 times based on mg/m 2 /day). Maternal toxicity (decreased body weight gain) was observed in rabbits at the maximum tolerated dose of 10 mg/kg/day without adverse effects on offspring. Decreased body weight occurred in rat fetuses at ≥100 mg/kg/day, and in rat offspring at ≥32 mg/kg/day.
No effects were observed on maternal reproductive parameters or offspring survival, development, behavior, or reproductive function. There are, however, no adequate and well-controlled studies in pregnant women. Because animal reproduction studies are not always predictive of human response, this drug should be used during pregnancy only if clearly needed.
🧒 Pediatric Use ▾
Pediatric Use Safety and efficacy in neonates and infants less than 6 months of age have not been established. Use of cefdinir for the treatment of acute maxillary sinusitis in pediatric patients (age 6 months through 12 years) is supported by evidence from adequate and well-controlled studies in adults and adolescents, the similar pathophysiology of acute sinusitis in adult and pediatric patients, and comparative pharmacokinetic data in the pediatric population.
🧓 Geriatric Use ▾
Geriatric Use Efficacy is comparable in geriatric patients and younger adults. While cefdinir has been well-tolerated in all age groups, in clinical trials geriatric patients experienced a lower rate of adverse events, including diarrhea, than younger adults. Dose adjustment in elderly patients is not necessary unless renal function is markedly compromised (see DOSAGE AND ADMINISTRATION ).
🆘 Overdosage ▾
OVERDOSAGE Information on cefdinir overdosage in humans is not available. In acute rodent toxicity studies, a single oral 5600 mg/kg dose produced no adverse effects. Toxic signs and symptoms following overdosage with other β-lactam antibiotics have included nausea, vomiting, epigastric distress, diarrhea, and convulsions.
Hemodialysis removes cefdinir from the body. This may be useful in the event of a serious toxic reaction from overdosage, particularly if renal function is compromised.

CLINICAL PHARMACOLOGY Pharmacokinetics and Drug Metabolism Absorption Oral Bioavailability Maximal plasma cefdinir concentrations occur 2 to 4 hours postdose following capsule or suspension administration. Plasma cefdinir concentrations increase with dose, but the increases are less than dose-proportional from 300 mg (7 mg/kg) to 600 mg (14 mg/kg). Following administration of suspension to healthy adults, cefdinir bioavailability is 120% relative to capsules.
Estimated bioavailability of cefdinir capsules is 21% following administration of a 300 mg capsule dose, and 16% following administration of a 600 mg capsule dose. Estimated absolute bioavailability of cefdinir suspension is 25%. Cefdinir oral suspension of 250 mg/5 mL strength was shown to be bioequivalent to the 125 mg/5 mL strength in healthy adults under fasting conditions.
Effect of Food The C max and AUC of cefdinir from the capsules are reduced by 16% and 10%, respectively, when given with a high-fat meal. In adults given the 250 mg/5 mL oral suspension with a high-fat meal, the C max and AUC of cefdinir are reduced by 44% and 33%, respectively. The magnitude of these reductions is not likely to be clinically significant because the safety and efficacy studies of oral suspension in pediatric patients were conducted without regard to food intake.
Therefore, cefdinir may be taken without regard to food. Cefdinir Capsules Cefdinir plasma concentrations and pharmacokinetic parameter values following administration of single 300 and 600 mg oral doses of cefdinir to adult subjects are presented in the following table: Mean (±SD) Plasma Cefdinir Pharmacokinetic Parameter Values Following Administration of Capsules to Adult Subjects Dose C max (mcg/mL) T max (hr) AUC (mcg•hr/mL) 300 mg 1.6 (0.55) 2.9 (0.89) 7.05 (2.17) 600 mg 2.87 (1.01) 3 (0.66) 11.1 (3.87) Cefdinir Suspension Cefdinir plasma concentrations and pharmacokinetic parameter values following administration of single 7 and 14 mg/kg oral doses of cefdinir to pediatric subjects (age 6 months to 12 years) are presented in the following table: Mean (±SD) Plasma Cefdinir Pharmacokinetic Parameter Values Following Administration of Suspension to Pediatric Subjects Dose C max (mcg/mL) t max (hr) AUC (mcg•hr/mL) 7 mg/kg 2.3 (0.65) 2.2 (0.6) 8.31 (2.5) 14 mg/kg 3.86 (0.62) 1.8 (0.4) 13.4 (2.64) Multiple Dosing Cefdinir does not accumulate in plasma following once- or twice-daily administration to subjects with normal renal function.
Distribution The mean volume of distribution (Vd area ) of cefdinir in adult subjects is
0.35L/kg (±0.29); in pediatric subjects (age 6 months to 12 years), cefdinir Vd area is
0.67L/kg (±0.38). Cefdinir is 60% to 70% bound to plasma proteins in both adult and pediatric subjects; binding is independent of concentration. Skin Blister In adult subjects, median (range) maximal blister fluid cefdinir concentrations of 0.65 (0.33 to 1.1) and 1.1 (0.49 to 1.9) mcg/mL were observed 4 to 5 hours following administration of 300 and 600 mg doses, respectively.
Mean (±SD) blister C max and AUC (0-∞) values were 48% (±13) and 91% (±18) of corresponding plasma values. Tonsil Tissue In adult patients undergoing elective tonsillectomy, respective median tonsil tissue cefdinir concentrations 4 hours after administration of single 300 and 600 mg doses were 0.25 (0.22 to 0.46) and 0.36 (0.22 to 0.8) mcg/g. Mean tonsil tissue concentrations were 24% (±8) of corresponding plasma concentrations.
Sinus Tissue In adult patients undergoing elective maxillary and ethmoid sinus surgery, respective median sinus tissue cefdinir concentrations 4 hours after administration of single 300 and 600 mg doses were <0.12 (<0.12 to 0.46) and 0.21 (<0.12 to 2) mcg/g. Mean sinus tissue concentrations were 16% (±20) of corresponding plasma concentrations. Lung Tissue In adult patients undergoing diagnostic bronchoscopy, respective median bronchial mucosa cefdinir concentrations 4 hours after administration of single 300 and 600 m…

💬 Information for Patients ▾
Information for Patients Patients should be counseled that antibacterial drugs including cefdinir should only be used to treat bacterial infections. They do not treat viral infections (e.g., the common cold). When cefdinir is prescribed to treat a bacterial infection, patients should be told that although it is common to feel better early in the course of therapy, the medication should be taken exactly as directed.
Skipping doses or not completing the full course of therapy may (1) decrease the effectiveness of the immediate treatment and (2) increase the likelihood that bacteria will develop resistance and will not be treatable by cefdinir or other antibacterial drugs in the future. Antacids containing magnesium or aluminum interfere with the absorption of cefdinir. If this type of antacid is required during cefdinir therapy, cefdinir should be taken at least 2 hours before or after the antacid.
Iron supplements, including multivitamins that contain iron, interfere with the absorption of cefdinir. If iron supplements are required during cefdinir therapy, cefdinir should be taken at least 2 hours before or after the supplement. Iron-fortified infant formula does not significantly interfere with the absorption of cefdinir.
Diarrhea is a common problem caused by antibiotics which usually ends when the antibiotic is discontinued. Sometimes after starting treatment with antibiotics, patients can develop watery and bloody stools (with or without stomach cramps and fever) even as late as two or more months after having taken the last dose of the antibiotic. If this occurs, patients should contact their physician as soon as possible.
