Why Prescribed
For the temporary relief of discomfort and redness from minor eye irritation. It is prescribed in combination with other drugs such as phenylephrine, naphazoline, and tetrahydrozoline.

How It Works
The Mineral zinc is an integral component in the proper functioning of several important enzymes involved in wound healing and the general maintenance and proper hydration of certain body tissues. Zinc sulfate ophthalmic solution has a mild astringent effect (that is, it causes tissues to contract when applied topically), which can help to shrink the tiny blood vessels in the whites of the eye (sclera) and so relieve redness and irritation.

Range and Frequency
Instill 1 to 2 drops in the affected eye(s) up to four times a day.

Onset of Effect
Rapid

Duration of Action
Up to several hours

Dietary Advice
No special restrictions

Storage
Store in a tightly sealed container away from heat and direct light. Do not allow the solution to freeze.

Missed Dose
Instill the missed dose as soon as possible unless it is near the time for the next dose. In that case, skip the missed dose and go back to your regular schedule. Do not double the next dose.

Stopping the Drug
You may stop applying this drug, or resume using it after discontinuing, as comfort dictates. No complications are expected.

Prolonged Use
Eye drops containing zinc sulfate should generally not be used for self-medication for more than three days. If relief is not achieved in this time, or if redness and irritation persist or worsen, discontinue using it and contact your doctor or ophthalmologist right away.

Over 60
No special problems are expected.

Driving and Hazardous Work
The use of this medication should not affect your ability to perform such tasks safely.

Alcohol
No special precautions are necessary.

Pregnancy
No problems are expected; however, if you are pregnant or plan to become pregnant and you have any concerns about the safe use of this or any other medication, consult your doctor.

Breast Feeding
Adequate studies on the use of ophthalmic zinc sulfate during breast-feeding have not been done; however, no adverse consequences have been reported. Consult your doctor for specific advice.

Infants and Children
No specific information is available on the use of this medication by children.

Special Concerns
Contact your ophthalmologist or general practitioner right away if you experience eye pain, changes in vision, or if eye irritation persists for more than 72 hours. To use the eye drops, first wash your hands. Tilt your head back. Gently apply pressure to the inside corner of the lower eyelid and with the index finger of the same hand, pull downward on the eyelid to make a space. Drop the medicine into this space and close your eye. Apply pressure for one or two minutes while keeping the eye closed without blinking. Then wash your hands again. Make sure that the tip of the dropper does not touch your eye, finger, or any other surface.

Overdose Symptoms
No cases of overdose have been reported.

What to Do
An overdose is unlikely to occur; in case of accidental ingestion, call your doctor, emergency medical services (EMS), or the nearest poison control center right away.

Drug Interactions
No drug interactions have been reported, although phenylephrine, naphazoline, and tetrahydrozoline (other medications prescribed in combination with zinc sulfate ophthalmic solution) may adversely affect the action of certain glaucoma drops. Consult your doctor first before taking any other prescription or over-the-counter eye medications.

Food Interactions
No known food interactions

Disease Interactions
If you have glaucoma, do not use this medication without consulting your doctor first. It is not an over-the-counter substitute for Antibiotic or anti-inflammatory drops. Consult your doctor for specific advice if you have any other eye disorders or a history of allergic reaction to any other ophthalmic preparations.
