5 WARNINGS AND PRECAUTIONS
5.1 Corneal Toxicity
Prolonged use or abuse may lead to corneal epithelial toxicity which may manifest as epithelial defects and progress to permanent corneal opacification with accompanying visual loss.
5.2 Corneal Injury Due to Insensitivity
Patient should not touch the eye for approximately 20 minutes after using this anesthetic as accidental injuries can occur due to insensitivity of the eye.
6 ADVERSE REACTIONS
The following ocular adverse reactions are described elsewhere in the labeling:
- Corneal Toxicity [see Warnings and Precautions (5.1)]
- Corneal Injury due to Insensitivity [see Warnings and Precautions (5.2)]
The following adverse reactions have been identified following use of fluorescein sodium and benoxinate hydrochloride ophthalmic solution 0.25% / 0.4%: ocular hyperemia, burning, stinging, eye irritation, blurred vision and punctate keratitis. Because these reactions were reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
8 USE IN SPECIFIC POPULATIONS
There are no available data on the use of Altafluor Benox in pregnant women to inform any drug associated risk. Adequate animal reproduction studies have not been conducted with fluorescein sodium and/or benoxinate hydrochloride. Altafluor Benox should be given to a pregnant woman only if clearly needed.
There are no data on the presence of fluorescein sodium or benoxinate hydrochloride in human milk after ocular administration of Altafluor Benox, the effects on the breastfed infant, or the effects on milk production.
The developmental and health benefits of breastfeeding should be considered, along with the mother’s clinical need for Altafluor Benox and any potential adverse effects on the breastfed infant from Altafluor Benox.
8.4 Pediatric Use
The safety and effectiveness of Altafluor Benox have been established for pediatric patients. Use of Altafluor Benox is supported in pediatric patients by evidence from adequate and well controlled studies.
8.5 Geriatric Use
No overall differences in safety or effectiveness have been observed between elderly and younger patients.
