Phez Dosage/Direction for Use

Adults: Mydriasis: Instill 1 drop topically to each eye. If necessary, the dose may be repeated after 1 hour (As directed by the physician).
Pediatric: Mydriasis: Instill 1 drop topically to each eye. If necessary, the dose may be repeated after 1 hour. (As directed by the physician)
It is not usually necessary to exceed this dose.
Heavily pigmented irides may require larger doses and caution should be exercised to avoid overdosage.
The use in preterm and newborn infants is not recommended unless clearly necessary and only with caution because of safety concerns associated with the risk of systemic adverse reactions including transient increases in blood pressure. If treatment is medically justified, the lowest possible concentration and dose should be used and instillation of more than one drop per eye must be avoided.
Administration: The use of a drop of topical anaesthetic a few minutes before instillation of Phenylephrine is recommended to prevent stinging. Butacaine sulfate should not be used because it is incompatible with Phenylephrine.
Especially in infants, children and the elderly, it is advised to minimise systemic absorption and the risk for systemic adverse reactions by compressing the lacrimal sac at the medial canthus or gently closing the eye for a few minutes after instillation. To minimise cutaneous absorption, excess fluid should be wiped away from the periocular area.
Wash hands before and after application.
For topical ophthalmic use only.
To avoid contamination, do not touch dropper tip to eyelids or other surfaces when placing drops in eyes.
Solution should be applied to the conjunctival fornix unless otherwise directed.
Protect eyes from bright illumination while pupils are dilated.
