Warnings & Precautions

WARNINGS

Included as part of the PRECAUTIONS section.

PRECAUTIONS

Excessive Staining

Excess TissueBlue 0.025% should be removed from the eye immediately after staining.

Use In Specific Populations

Pregnancy

Risk Summary

There are no available data on the use of TissueBlue 0.025% in pregnant women to inform a drug associated risk. Systemic absorption of TissueBlue 0.025% in humans is expected to be negligible following intravitreal injection and subsequent removal of the drug at the completion of surgical procedures. Due to the negligible systemic exposure, it is not expected that maternal use of TissueBlue 0.025% will result in fetal exposure to the drug.

Adequate animal reproduction studies were not conducted with TissueBlue 0.025%.

Lactation

Risk Summary

No data are available regarding the presence of Brilliant Blue G in human milk after intraocular administration of TissueBlue 0.025%, or the effects on the breastfed infant or the effects on milk production. However, breastfeeding is not expected to result in exposure of the child to Brilliant Blue G due to the expected negligible systemic exposure of BBG in humans following intravitreal injection and subsequent removal of the drug at the completion of surgical procedures.

Pediatric Use

The safety and effectiveness of TissueBlue 0.025% in pediatric patients has not been established.

Geriatric Use

No overall differences in safety or effectiveness were observed between elderly and younger adult patients.

Clinical Pharmacology

CLINICAL PHARMACOLOGY

Mechanism Of Action

Brilliant Blue G has been shown to selectively stain the ILM, but not the epiretinal membrane nor the retina, making it easier to visualize the membrane for removal, although the exact mechanism of this selectivity has not been elucidated.
