Warnings and Precautions
Corneal injury with Intracameral Use
Not for injection or intraocular use. Do not use intracamerally because use of TetracaineHydrochloride Ophthalmic Solution 0.5% may lead to damage of the corneal endothelial cells.
Prolonged use or abuse may lead to corneal epithelial toxicity and may manifest as epithelial defects which may progress to permanent corneal damage.
Corneal Injury due to Insensitivity
Patients should not touch the eye for at least 10-20 minutes after using anesthetic as accidental injuries can occur due to insensitivity of the eye.
The following serious ocular adverse reactions are described elsewhere in the labeling:
- Corneal injury with Intracameral Use [See Warnings and Precautions (5.1)]
- Corneal Toxicity [See Warnings and Precautions (5.2)]
- Corneal Injury due to Insensitivity [See Warnings and Precautions (5.3)]
The following adverse reactions have been identified following use of Tetracaine Hydrochloride Ophthalmic Solution 0.5%. Because these reactions are 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.
Ocular Adverse Reactions
Transient stinging, burning, and conjunctival redness, eye irritation, eye pain, ocular discomfort.
USE IN SPECIFIC POPULATIONS
There are no adequate and well-controlled studies with Tetracaine Hydrochloride Ophthalmic Solution 0.5% in pregnant women. Animal developmental and reproductive toxicity studies with tetracaine hydrochloride have not been reported in the published literature.
There are no data to assess whether Tetracaine Hydrochloride Ophthalmic Solution 0.5% is excreted in human milk or to assess its effects on milk production/excretion. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Tetracaine Hydrochloride Ophthalmic Solution 0.5% and any potential adverse effects on the breastfed child from Tetracaine Hydrochloride Ophthalmic Solution 0.5% or from the underlying maternal condition.
Females and Males of Reproductive Potential
No human data on the effect of Tetracaine Hydrochloride Ophthalmic Solution 0.5% on fertility are available.
Safety in the pediatric population has been demonstrated in clinical trials. Efficacy of tetracaine hydrochloride ophthalmic solution for use in pediatric patients has been extrapolated from adequate and well controlled clinical trials in the adult population.
No overall differences in safety or effectiveness of tetracaine hydrochloride ophthalmic solution have been observed between elderly and younger patients.
Prolonged use of a topical ocular anesthetic including TetracaineHydrochloride Ophthalmic Solution 0.5% may produce permanent corneal opacification and ulceration with accompanying visual loss. Symptoms related to systemic toxicity consist mainly of effects on the neurologic and cardiovascular systems.

Tetracaine Ophthalmic Solution - Clinical Pharmacology
Mechanism of Action
Tetracaine blocks sodium ion channels required for the initiation and conduction of neuronal impulses thereby affecting local anesthesia.
The systemic exposure to tetracaine following topical ocular administration of Tetracaine Hydrochloride Ophthalmic Solution 0.5% has not been studied. Tetracaine hydrochloride is metabolized by plasma pseudocholinesterases and nonspecific esterases in ocular tissues.
Carcinogenesis, Mutagenesis, Impairment of Fertility
Studies to assess the genotoxicity of tetracaine hydrochloride have not been reported in the published literature. Long-term animal studies have not been conducted to evaluate the carcinogenic potential of tetracaine hydrochloride.
Animal studies to assess the effects of tetracaine hydrochloride on fertility have not been reported in the published literature.
Topical administration of tetracainehydrochloride ophthalmic solution results in localized temporary anesthesia. The maximum effect is achieved within 10–20 seconds after instillation, with efficacy lasting 10–20 minutes. Duration of effect can be extended with repeated dosing. [see Corneal toxicity (5.2) and Overdosage (10)].
