Available Forms
Ophthalmic solution, 5%, 5 mL plastic bottle
Mechanism of Action
Anticholinergic; blocks the response of the iris sphincter and the accommodative muscle of the ciliary body to cholinergic stimulation, producing mydriasis and paralysis of accommodation. The label characterizes the resulting mydriasis and cycloplegia as moderately long-acting.
Warnings & Precautions
Route restriction: Topical ophthalmic use only; not for injection.
Keratoconus: May produce a fixed dilated pupil; weigh risk against benefit.
Increased susceptibility: Down syndrome, children with brain damage, and the elderly; extreme caution in infants and small children.
Systemic anticholinergic poisoning: Excessive use in pediatric patients, or in those with a history of susceptibility to belladonna alkaloids, may produce systemic symptoms.
Systemic absorption: Compress the lacrimal sac by digital pressure for 2 to 3 minutes after instillation.
Amblyopia in early infancy: The cycloplegia produced is possibly associated with development of amblyopia, which is why the drug is not used during the first 3 months of life.
Common Side Effects
Ocular: Transient stinging and burning; eye irritation not present before therapy; increased sensitivity of the eyes to light.
Ocular, prolonged use: Local irritation with follicular conjunctivitis, vascular congestion, edema, exudates, and eczematoid dermatitis.
