Cyclopentolate Hydrochloride

Anticholinergics Prescription

Indications

Mydrate ophthalmic solution is used chiefly to bring about mydriasis and cycloplegia for diagnostic eye examinations.

⚠️ Always consult a registered physician before taking any medicine.

Pharmacology

Cyclopentolate belongs to the anticholinergic class of medicines. Applied as eye drops, it relaxes the sphincter muscle of the iris along with the ciliary muscles, producing a rapid and pronounced effect on pupil dilation and the eye's focusing ability. This effect peaks within 15 to 60 minutes of application, and the eye typically returns to normal within 24 hours. In people with darker eye colour, the onset of these effects tends to be slower and their duration longer.

Dosage Reference

⚠️ Reference ranges from official sources only. Consult your doctor for personalized dosing.

Adults: Adults and children over 1 year, for producing mydriasis and cycloplegia before eye examinations: instil 1 drop in the eye(s), with a second drop after 5 minutes if needed. Drops should be given 40 to 50 minutes before the procedure. To reduce absorption into the body, press a finger against the tear duct (inner corner of the eye) for 2 to 3 minutes after each drop, or alternatively, keep the eyelids closed for 2 to 5 minutes. People with darker (heavily pigmented) irises may need higher doses. Vision should return to normal, with mydriasis and cycloplegia fully resolved, within 24 hours. Use in children: Infants, young children, and children with fair hair or blue eyes may be more sensitive to cyclopentolate's effects, raising their risk of side effects during treatment. Its use in children has been linked to psychotic reactions and behavioural disturbances.
