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.

5 Warnings and Precautions

Newly added subsection:

5.4 Embryo-Fetal Toxicity

Based on findings in animals and mechanism of action, Mitosol® can cause fetal harm when administered to a pregnant woman. In animal reproduction studies, parenteral administration of mitomycin resulted in teratogenicity [see Use in Specific Populations (8.1, 8.3) and Clinical Pharmacology (12.1)].

6 Adverse Reactions

Newly added bullet line listing:

The following clinically significant adverse reactions are described elsewhere in the labeling:

Cell Death [see Warnings and Precautions (5.1)]
Hypotony [see Warnings and Precautions (5.2)]
Cataract Formation [see Warnings and Precautions (5.3)]

6.1 Ophthalmic Adverse Reactions

Additions and/or revisions underlined:

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. The most frequent adverse reactions to Mitosol® occur locally, as an extension of the pharmacological activity of the drug. These reactions include …

8 Use in Specific Populations

8.1 Pregnancy

PLLR conversion; additions and/or revisions underlined:

Risk Summary

Based on findings in animals and mechanism of action [see Clinical Pharmacology (12.1)], Mitosol® can cause fetal harm when administered to a pregnant woman. There are no available data on Mitosol® use in pregnant women to inform the drug-associated risk. In animal reproduction studies, parenteral administration of mitomycin resulted in teratogenicity (see Data). Advise pregnant women of the potential risk to a fetus.

The estimated background risk of major birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% - 4% and 15% - 20%, respectively.

Data

Animal Data

Parenteral administration of mitomycin in animal reproduction studies produced fetal malformations and embryofetal lethality.

8.2 Lactation

PLLR conversion; additions and/or revisions underlined:

Risk Summary

There are no data on the presence of mitomycin in human milk, the effects on the breastfed child, or the effects on milk production. Because of the potential for serious adverse reactions in a breastfed child, advise women not to breastfeed during and for 1 week following administration of Mitosol®.

Newly added subsection:

8.3 Females and Males of Reproductive Potential

Mitosol® can cause fetal harm when administered to pregnant women [see Use in Specific Populations (8.1)].

Pregnancy Testing

Verify pregnancy status in females of reproductive potential prior to using Mitosol®.

17 PCI/PI/MG (Patient Counseling Information/Patient Information/Medication Guide)

PATIENT COUNSELING INFORMATION

Additions and/or revisions underlined:

Instruct patients to discuss with their physician if they are pregnant or if they might become pregnant [see Use in Specific Populations (8.1)].
Nursing mothers should be advised that it is not known if Mitosol® is excreted in human milk. Because of the potential for serious adverse reactions in a breastfed child, advise women not to breastfeed during and for 1 week following administration of Mitosol® [see Use in Specific Populations (8.2)].
