Italics	For the most part, italics indicate an FDA comment such as: Additions and/or revisions underlined These italics usually appear at the beginning of the section. In some cases, italics may be an inherent part of the label, and will most often appear in the body of the section.
Underlines	Any text that is underlined indicates text that has been added or revised. There are exceptions where underlining occurs in a section subtitle or heading. This is the case when there is just one word underlined in the body of the text.

PCI/PI/MG	Patient Counseling Information (PLR format only) - summarizes the information that a health care provider should convey to a patient (or caregiver when applicable) when a counseling discussion is taking place (e.g., a physician prescribing a drug during an office visit, a nurse providing discharge instructions at a hospital, or a pharmacist conveying information at a pharmacy). Patient Information - FDA approved patient labeling. Medication Guide - paper handouts that come with many prescription medicines. The guides address issues that are specific to particular drugs and drug classes, and they contain FDA-approved information that can help patients avoid serious adverse events.

Only NDAs and CDER regulated BLAs are included in this database. ANDAs are not included.

Applications that remain active, even if the product has been discontinued, undergo safety-related labeling changes.

8 Use in Specific Populations

8.1 Pregnancy

PLLR conversion:

Risk Summary

Available data from published observational studies, case series, and case reports over several decades with cephalosporin use, including cefixime, in pregnant women have not established drug- associated risks of major birth defects, miscarriage, or adverse maternal or fetal outcomes (see Data). Reproduction studies have been performed in mice and rats at doses equivalent to 40 and 80 times, respectively, the adult human recommended dose and have revealed no evidence of harm to the fetus due to cefixime (see Data).

The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risks of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Clinical Considerations

Disease-Associated Maternal and/or Embryo/Fetal Risk

Maternal gonorrhea may be associated with preterm birth, low neonatal birth weight, chorioamnionitis, intrauterine growth restriction, small for gestational age and premature rupture of membranes. Perinatal transmission of gonorrhea to the offspring can result in infant blindness, joint infections, and bloodstream infections.

Data

Human Data

While available studies cannot definitively establish the absence of risk, published data from prospective cohort studies, case series, and case reports over several decades have not identified a consistent association with cephalosporin use, including cefixime, during pregnancy, and major birth defects, miscarriage, or other adverse maternal or fetal outcomes. Available studies have methodological limitations, including small sample size, retrospective data collection, and inconsistent comparator groups.

Animal Data

The results of embryo-fetal development studies in mice and rats show that cefixime, at doses up to 3200 mg/kg/day administered during the period of organogenesis did not adversely affect development. In these studies, in mice and rats, cefixime did not affect postnatal development or reproductive capacity of the F1 generation or fetal development of the F2 generation. In an embryo- fetal development study in rabbits, cefixime at doses of 3.2, 10 or 32 mg/kg given daily during the period of organogenesis (gestation days 6 through 18) resulted in abortions and/or maternal deaths at doses > 10 mg/kg (typically associated with the administration of antibiotics in this species), but no malformations were reported at lower doses. A pre- and post-natal development study of cefixime at oral doses up to 3200 mg/kg/day in rats demonstrated no effect on the duration of pregnancy, process of parturition, development and viability of offspring, or reproductive capacity of the F1 generation and development of their fetuses (F2).

8.2 Lactation

PLLR conversion:

Risk Summary

There are no available data on the presence of cefixime in human milk, the effects on the breast- fed infant, or the effects on milk production. Cefixime is present in animal milk (see Data). When a drug is present in animal milk, it is likely the drug will be present in human milk. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for SUPRAX and any potential adverse effects on the breast-fed infant from SUPRAX or from the mother’s underlying condition.

Data

In a study on disposition of cefixime in pregnant and lactating rats, continuous intra-peritoneal

infusion of 2.54 mg/kg/day of C-cefixime from days 10 to 14 postpartum resulted in steady state

plasma concentrations of radioactivity in the dams that were 70 times greater than in their nursing pups.

After 102 hours of drug infusion, total radioactivity in the body of the pups, including the stomach

and intestinal contents, was 1.5% of the C-cefixime estimated to be in the mother's body at steady

state.

8.4 Pediatric Use

Additions and/or revisions underlined:

The safety and effectiveness of SUPRAX have been established in pediatric patients 6 months of age and older. Safety and effectiveness of SUPRAX in pediatric patients younger than 6 months of age have not been established. The incidence of gastrointestinal adverse reactions, including diarrhea and loose stools, in the pediatric patients receiving the SUPRAX for oral suspension, was comparable to the incidence seen in adult patients receiving tablets.

5 Warnings and Precautions

5.6 Risk in Patients with Phenylketonuria

Newly added subsection:

Phenylalanine can be harmful to patients with phenylketonuria (PKU). SUPRAX chewable tablets contain aspartame, a source of phenylalanine. Each 100 mg, 150 mg and 200 mg strength contains 3.3 mg, 5 mg and 6.7 mg of phenylalanine, respectively. Before prescribing SUPRAX chewable tablets in a patient with PKU, consider the combined daily amount of phenylalanine from all sources, including SUPRAX chewable tablets.

6 Adverse Reactions

6.2 Post-marketing Experience

Additions and/or revisions underlined:

The following adverse reactions have been reported following the post-approval use of cefixime ...

PATIENT COUNSELING INFORMATION

17.1 Information for Patients

Additions and/or revisions underlined:

Counsel patients with phenylketonuria that SUPRAX chewable tablets contain aspartame, a source of phenylalanine as follows: Each SUPRAX chewable tablet contains 3.3 mg, 5 mg and 6.7 mg of phenylalanine per 100 mg, 150 mg and 200 mg strength, respectively.
