Common use

Cyclogyl 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

Cyclogyl 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. 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 Cyclogyl only under medical supervision, especially in infants, young children, or elderly patients, as they may be more sensitive to systemic side effects. Caution is advised in people with Down syndrome, glaucoma, or cardiovascular conditions. Temporary blurred vision and light sensitivity may occur - avoid driving or operating machinery until vision returns to normal. Wear sunglasses after use to reduce discomfort from bright lights.

Contraindications

Cyclogyl should not be used in individuals with narrow-angle glaucoma or hypersensitivity to cyclopentolate or other anticholinergic agents. It is contraindicated in patients with a known history of severe adverse reactions to eye medications. Use in premature infants is not recommended due to increased risk of side effects. Always consult your healthcare provider before use.

Possible side effect

Common side effects include stinging or burning in the eye, blurred vision, and light sensitivity. In children or sensitive individuals, systemic effects such as dry mouth, flushing, restlessness, or confusion may occur. Rare but serious reactions include increased intraocular pressure, hallucinations, or seizures. Seek medical attention if any unusual or severe symptoms occur.

Drug interaction

Cyclogyl may interact with other anticholinergic medications, increasing the risk of side effects such as dry mouth, confusion, or urinary retention. Caution should be taken when used with CNS stimulants, antihistamines, or psychiatric drugs. Inform your doctor about all medications you are using, including eye treatments and over-the-counter products. Do not combine with other mydriatics unless instructed by a physician.

Missed dose

Cyclogyl is generally used as a single or occasional dose during eye exams, so missing a dose is uncommon. If using it for treatment, apply the missed dose as soon as remembered unless it's almost time for the next one. Do not double the dose. Always follow your doctor's specific instructions.

Overdose

Overdose, especially in children, can lead to toxic systemic effects such as hallucinations, agitation, rapid heartbeat, or seizures. In case of accidental ingestion or overdose, seek emergency medical attention immediately. Store out of reach of children to prevent accidental misuse. Overuse in the eye can also cause prolonged dilation and blurred vision.

Storage

Store Cyclogyl at room temperature (15-25°C / 59-77°F) away from light, moisture, and heat. Keep the bottle tightly closed when not in use. Do not freeze. Discard the product after the expiration date or if contamination is suspected.
