These highlights do not include all the information needed to use ZERVIATE

ZERVIATE ^® (cetirizine ophthalmic solution) 0.24% is indicated for the treatment of ocular itching associated with allergic conjunctivitis.

The recommended dosage of ZERVIATE ^®is to instill one drop in each affected eye twice daily (approximately 8 hours apart).

The single-use containers are to be used immediately after opening and can be used to dose both eyes. Discard the single-use container and any remaining contents after administration. The single-use containers should be stored in the original foil pouch until ready to use.

Cetirizine ophthalmic solution, 0.24% is a sterile, buffered, clear, colorless aqueous solution containing cetirizine 0.24% (equivalent to cetirizine hydrochloride 0.29%).

None.

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trial of a drug cannot be directly compared to rates in clinical trials of another drug and may not reflect the rates in practice.

In seven clinical trials, patients with allergic conjunctivitis or those at a risk of developing allergic conjunctivitis received one drop of either cetirizine (N=511) or vehicle (N=329) in one or both eyes. The most commonly reported adverse reactions occurred in approximately 1–7% of patients treated with either ZERVIATE ^® or vehicle. These reactions were ocular hyperemia, instillation site pain, and visual acuity reduced.

ZERVIATE ^® is a sterile ophthalmic solution containing cetirizine, which is a histamine-1 (H1) receptor antagonist, for topical administration to the eyes. Cetirizine hydrochloride is a white, crystalline, water-soluble powder with a molecular weight of 461.8 and a molecular formula of C ₂₁H ₂₅ClN ₂O ₃•2HCl. The chemical structure is presented below:

Chemical Name:

( RS)-2-[2-[4-[(4-Chlorophenyl) phenylmethyl] piperazin-1-yl] ethoxy] acetic acid, dihydrochloride

Each mL of ZERVIATE ^® contains an active ingredient [cetirizine 2.40 mg (equivalent to 2.85 mg of cetirizine hydrochloride)] and the following inactive ingredients: benzalkonium chloride 0.010% (preservative); glycerin; sodium phosphate, dibasic; edetate disodium; polyethylene glycol 400; polysorbate 80; hypromellose; hydrochloric acid/sodiumhydroxide (to adjust pH); and water for injection. ZERVIATE ^®solution has a pH of approximately 7.0 and osmolality of approximately 300 mOsm/kg.

The efficacy of ZERVIATE ^®(cetirizine ophthalmic solution) 0.24% was established in three randomized, double-masked, placebocontrolled, conjunctival allergen challenge (CAC) clinical trials in patients with a history of allergic conjunctivitis. Onset and duration of action were evaluated in two of these trials in which patients were randomized to receive ZERVIATE ^®or vehicle ophthalmic solutions. Patients were evaluated with an ocular itching severity score ranging from 0 (no itching) to 4 (incapacitating itch) at several time points after CAC administration. Table 1 displays data from the mean ocular itching severity scores after ocular administration of an antigen using the CAC model. A one unit difference compared to vehicle is considered a clinically meaningful change in the ocular itching severity score.

Patients treated with ZERVIATE ^® demonstrated statistically and clinically significantly less ocular itching compared to vehicle at 15 minutes and 8 hours after treatment.

ZERVIATE ^® is a sterile, buffered, clear, colorless aqueous solution containing cetirizine 0.24% (equivalent to cetirizine hydrochloride 0.29%) supplied in 5 low-density polyethylene 0.2 mL single-use containers within a foil pouch.

• Risk of Contamination: Advise patients not to touch dropper tip to eyelids or surrounding areas, as this may contaminate the dropper tip and ophthalmic solution. Advise patients to discard single-use containers after each use.

• Concomitant Use of Contact Lenses: Advise patients not to wear contact lenses if their eyes are red. Advise patients that ZERVIATE ^® should not be used to treat contact lens-related irritation. Advise patients to remove contact lenses prior to instillation of ZERVIATE ^®. The preserative in ZERVIATE ^® solution, benzalkonium chloride, may be absorbed by soft contact lenses. Lenses may be reinserted 10 minutes following administration of ZERVIATE ^®.
• Administration: Advise patients that the solution from one single-use container is to be used immediately after opening. Advise patients that the single-use container can be used to dose both eyes. Discard the single-use container and remaining contents immediately after administration.
• Storage of Single-use Containers: Instruct patients to store single-use containers in the original foil pouch until ready to use.
