ANDA	Abbreviated New Drug Application
BLA	Biologics License Application
CDER	Center for Drug Evaluation and Research
MG	Medication Guide
NDA	New Drug Application
PCI	Patient Counseling Information
PI	Patient Information
PLR	Physician Labeling Rule

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.

Sections

BW	Box Warning
WP	Warnings and Precautions all in one section (PLR-format) Warnings as one section (pre-PLR format) Precautions as one section (pre-PLR format)
AR	Adverse Reactions (in pre-PLR format, this may be a subheading under precautions).
DI	Drug Interactions (in pre-PLR format, this may be a subheading under precautions).
USP	Use in Specific Populations (Inclusive on one or more of the following: Pregnancy; Lactation (PLLR- format); Nursing Mothers (pre-PLLR format); Females and Males of Reproductive Potential (PLLR format only); Pediatric Use, Geriatric Use, Renal Impairment, Hepatic Impairment, Sex, Race (these last six may be a subheading of precautions if label in pre-PLLR format.
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

Clindesse has not been studied in pregnant women. The systemic exposure (based on AUC and Cmax) of Clindesse administered intravaginally is substantially lower than clindamycin administered intravenously [see Clinical Pharmacology (12.3)]; therefore, maternal use is not likely to result in significant fetal exposure to the drug. Available data from published observational studies and randomized controlled trials over decades of use with other clindamycin products during pregnancy have not identified an increased risk of major birth defects, miscarriage, or other adverse maternal and fetal outcomes.

In animal reproduction studies, no adverse developmental outcomes were observed in pregnant rats and mice administered oral doses of clindamycin at up to 600 mg/kg/day (58 and 29 times, respectively, the recommended human dose based on a body surface area comparison) (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 risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively.

Data

Animal Data

Reproduction studies have been performed in rats and mice using oral doses of clindamycin up to 600 mg/kg/day (58 and 29 times, respectively, the recommended human dose based on body surface area comparisons) and have revealed no evidence of harm to the fetus due to clindamycin.

8.2 Lactation

PLLR conversion:

Risk Summary

The systemic exposure (based on AUC and Cmax) of Clindesse is substantially lower than intravenous administration of clindamycin [see Clinical Pharmacology (12.3)]; therefore, adverse effects on the breastfed infant are not expected from transfer of clindamycin into breastmilk. There are no data on the effect of clindamycin on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for Clindesse and any potential adverse effects on the breastfed infant from Clindesse or from the underlying maternal condition.

8.3 Females and Males of Reproductive Potential

PLLR conversion:

Contraception

Clindesse contains mineral oil that may weaken latex or rubber products such as condoms or vaginal contraceptive diaphragms. Therefore, the use of such barrier contraceptives is not recommended concurrently or for 5 days following treatment with Clindesse. During this time period, condoms may not be reliable for preventing pregnancy or for protecting against transmission of HIV and other sexually transmitted diseases [see Warnings and Precautions (5.2)].
