What is Mydriacyl used for?
This medication is used to widen (dilate) the pupil of the eye in preparation for certain eye examinations. It belongs to a class of drugs known as anticholinergics. Tropicamide works by relaxing certain eye muscles.
How to use Mydriacyl Drops
To apply eye drops, wash your hands first. To avoid contamination, do not touch the dropper tip or let it touch your eye or any other surface.
If you are wearing contact lenses, remove them before using this medication. Ask your doctor when you may replace your contact lenses.
Tilt your head back, look upward, and pull down the lower eyelid to make a pouch. Hold the dropper directly over your eye and place 1 or 2 drops into the pouch, usually 15 to 20 minutes before an eye examination or as directed by your doctor. Look downward and gently close your eyes for 1 to 2 minutes. Place one finger at the corner of your eye (near the nose) and apply gentle pressure for 2 to 3 minutes. This will prevent the medication from draining out and being absorbed by your body. Try not to blink and do not rub your eye. Repeat these steps for your other eye if so directed.
Do not rinse the dropper. Replace the dropper cap after each use.
If you are using another kind of eye medication (e.g., drops or ointments), wait at least 5 to 10 minutes before applying other medications. Use eye drops before eye ointments to allow the drops to enter the eye.
Wash your hands after using this medication. If giving this medication to a child, do not let the medication get into the child’s mouth. Also wash the child’s hands after giving this medication.
Each mL of MYDRIACYL® (tropicamide ophthalmic solution, USP) contains: Active: tropicamide 0.5% or 1%. Preservative: benzalkonium chloride 0.01%. Inactives: sodium chloride, edetate disodium, hydrochloric acid and/or sodium hydroxide (to adjust pH), purified water; pH range 4.0-5.8.
This anticholinergic preparation blocks the responses of the sphincter muscle of the iris and the ciliary muscle to cholinergic stimulation, dilating the pupil (mydriasis). The stronger preparation (1%) also paralyzes accommodation. This preparation acts in 15-30 minutes, and the duration of activity is approximately 3-8 hours. Complete recovery from mydriasis in some individuals may require 24 hours. The weaker strength may be useful in producing mydriasis with only slight cycloplegia. Heavily pigmented irides may require more doses than lightly pigmented irides.
INDICATIONS AND USAGE
For mydriasis and cycloplegia for diagnostic procedures.
FOR TOPICAL OPHTHALMIC USE ONLY. NOT FOR INJECTION.
This preparation may cause CNS disturbances which may be dangerous in pediatric patients. The possibility of psychotic reactions and behavioral disturbances due to hypersensitivity to anticholinergic drugs should be considered.
Mydriatics may produce a transient elevation of intraocular pressure.
Remove contact lenses before using.
The lacrimal sac should be compressed by digital pressure for two to three minutes after instillation to reduce excessive systemic absorption.
information for Patients
Do not touch dropper tip to any surface, as this may contaminate the solution. Patient should be advised not to drive or engage in potentially hazardous activities while pupils are dilated. Patient may experience sensitivity to light and should protect eyes in bright illumination during dilation. Parents should be warned not to get this preparation in their child’s mouth and to wash their own hands and the child’s hands following administration.Drug Interactions
Tropicamide may interfere with the antihypertensive action of carbachol, pilocarpine, or ophthalmic cholinesterase inhibitors.
Carcinogenesis, Mutagenesis, Impairment of Fertility
There have been no long-term studies done using tropicamide in animals to evaluate carcinogenic potential.
Animal reproduction studies have not been conducted with tropicamide. It is also not known whether tropicamide can cause fetal harm when administered to a pregnant woman or can affect reproduction capacity. Tropicamide should be given to a pregnant woman only if clearly needed.
It is not known whether this drug is excreted in human milk. Because many drugs are excreted in human milk, caution should be exercised when tropicamide is administered to a nursing woman.
Tropicamide may rarely cause CNS disturbances which may be dangerous in pediatric patients. Psychotic reactions, behavioral disturbances, and vasomotor or cardiorespiratory collapse in children have been reported with the use of anticholinergic drugs (see WARNINGS). Keep this and all medications out of the reach of children.
Ocular: Transient stinging, blurred vision, photophobia and superficial punctate keratitis have been reported with the use of tropicamide. Increased intraocular pressure has been reported following the use of mydriatics.
Non-Ocular: Dryness of the mouth, tachycardia, headache, allergic reactions, nausea, vomiting, pallor, central nervous system disturbances and muscle rigidity have been reported with the use of tropicamide. Psychotic reactions, behavioral disturbances, and vasomotor or cardiorespiratory collapse in children have been reported with the use of anticholinergic drugs.
DOSAGE AND ADMINISTRATION
For refraction, instill one or two drops of 1% solution in the eye(s), repeated in five minutes. If patient is not seen within 20 to 30 minutes, an additional drop may be instilled to prolong mydriatic effect. For examination of fundus, instill one or two drops of 0.5% solution 15 or 20 minutes prior to examination. Individuals with heavily pigmented irides may require higher strength or more doses. Mydriasis will reverse spontaneously with time, typically in 4 to 8 hours. However, in some cases, complete recovery may take up to 24 hours.
