Common use

Cyclopentolate is an ophthalmic medication used to dilate the pupil (mydriasis) and paralyze the eye's focusing muscle (cycloplegia) for eye examinations or pre-operative procedures. Its active ingredient, Cyclopentolate hydrochloride, is an anticholinergic agent that works by temporarily blocking certain receptors in the eye. This allows the eye care professional to better examine the lens, retina, and optic nerve. It is commonly used in both adults and children before eye diagnostic tests.

Dosage and direction

Cyclopentolate is applied as eye drops, usually 1-2 drops in the affected eye(s) as directed by an ophthalmologist. The effect begins within 15-45 minutes and may last up to 24 hours or longer in children. Follow these instructions carefully:

• Do not touch the dropper tip to any surface or the eye to avoid contamination
• After instilling the drop, gently press on the inner corner of the eye for 1-2 minutes to minimize absorption into the bloodstream

Precautions

Use Cyclopentolate only under medical supervision. Be especially careful with these groups:

• Infants, young children, or elderly patients may be more sensitive to systemic side effects
• People with Down syndrome, glaucoma, or cardiovascular conditions

After use, you may experience:

• Light sensitivity - wear sunglasses to reduce discomfort
