Phospholine Iodide (echothiophate iodide) for Ophthalmic Solution is a cholinesterase inhibitor that works by causing the pupil to shrink, decreasing the amount of fluid within the eye, and affecting certain eye muscles and is used to treat glaucoma by lowering the pressure inside the eye. Phospholine Iodide is also used to treat certain eye disorders involving eye accommodation (focusing). Common side effects of Phospholine Iodide include:
- temporary irritation/burning/stinging of the eye
- eye redness or tearing
- temporary blurred vision
- eyelid muscle twitching
- poor vision in dim light
- headache, or
- brow ache
The recommended dose of Phospholine Iodide for ophthalmic solution 0.03% is to instill into the affected eye(s) twice a day, just before retiring and in the morning. Phospholine Iodide may interact with other eye medications. Organophosphates may increase the effects of Phospholine Iodide. Gardeners, organophosphate plant or warehouse workers, or farmers may be exposed to organophosphates. Follow directions of your doctor and workplace safety guides regarding respiratory masks and washing and changing of clothes. Tell your doctor all medications and supplements you use. During pregnancy, Phospholine Iodide should be used only when prescribed. It is unknown if this drug passes into breast milk. Consult your doctor before breastfeeding.

Your doctor will want to check your retina before you use this medicine to determine if you have an increased risk of retinal detachment.

What is Prescribing information?
The FDA package insert formatted in easy-to-find categories for health professionals and clinicians.
Phospholine FDA Prescribing Information: Side Effects
- Although the relationship, if any, of retinal detachment to the administration of echothiophate iodide for ophthalmic solution has not been established, retinal detachment has been reported in a few cases during the use of echothiophate iodide for ophthalmic solution in adult patients without a previous history of this disorder.
- Stinging, burning, lacrimation, lid muscle twitching, conjunctival and ciliary redness, browache, induced myopia with visual blurring may occur.
- Activation of latent iritis or uveitis may occur.
- Iris cysts may form, and if treatment is continued, may enlarge and obscure vision. This occurrence is more frequent in children. The cysts usually shrink upon discontinuance of the medication, reduction in strength of the drops or frequency of instillation. Rarely, they may rupture or break free into the aqueous. Regular examinations are advisable when the drug is being prescribed for the treatment of accommodative esotropia.
- Prolonged use may cause conjunctival thickening, obstruction of nasolacrimal canals.
- Lens opacities occurring in patients under treatment for glaucoma with echothiophate iodide for ophthalmic solution have been reported and similar changes have been produced experimentally in normal monkeys. Routine examinations should accompany clinical use of the drug.
- Paradoxical increase in intraocular pressure may follow anticholinesterase instillation. This may be alleviated by prescribing a sympathomimetic mydriatic such as phenylephrine.
- Cardiac irregularities.
