Description
Cyclopentolate Hydrochloride 1% Eye prep is used before eye examinations and for treatment of certain eye conditions called uveitis. It works by enlarging the pupil of the eyes and helps the doctor visualize the eye more closely. Cyclopentolate is an anticholinergic agent that induces relaxation of the sphincter of the iris and the ciliary muscles. When applied topically to the eyes, it causes a rapid, intense cycloplegic and mydriatic effect that is maximal in 15 to 60 minutes; recovery usually occurs within 24 hours.

Pharmacology
Cyclopentolate is an anticholinergic agent that induces relaxation of the sphincter of the iris and the ciliary muscles. When applied topically to the eyes, it causes a rapid, intense cycloplegic and mydriatic effect that is maximal in 15 to 60 minutes; recovery usually occurs within 24 hours. The cycloplegic and mydriatic effects are slower in onset and longer in duration in patients who have dark pigmented irises.
Mechanism of action
Cyclopentolate relaxes the sphincter of the iris and ciliary muscles, producing pupil dilation and paralysis of accommodation, which helps in eye examination.
Dosage
Adults and children over 1 year: 1 drop instilled in the affected eye(s), repeated after 5 minutes if necessary. Administer 40-50 minutes prior to the procedure.
Infants <3 months: Not recommended.
Patients with heavily pigmented irises may require larger doses.
Administration
This medicine is for external use only. Take it in the dose and duration as advised by your doctor. Hold the dropper close to the eye without touching it. Gently squeeze the dropper and place the medicine inside the lower eyelid. Wipe off extra liquid. Apply pressure to the lacrimal sac for 2-3 minutes or keep eyelids closed for 2-5 minutes after administration.

If you miss a dose of Cyclopentolate Hydrochloride 1% Eye prep, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular schedule. Do not double the dose.
