Increased Eye Pressure and Glaucoma
Because Zylet contains a corticosteroid, prolonged use can increase pressure inside the eye.
This may lead to:
- Glaucoma
- Optic nerve damage
- Reduced visual acuity
- Changes in the field of vision
If Zylet is used for 10 days or longer, your healthcare provider should monitor your eye pressure.
Cataracts
Long-term use of corticosteroid eye drops can increase the risk of developing a posterior subcapsular cataract.
Tell your healthcare provider if you notice gradually worsening or cloudy vision.
Viral, Fungal, or Mycobacterial Eye Infections
Zylet should not be used for certain nonbacterial eye infections.
These include:
- Herpes simplex keratitis
- Chickenpox-related eye infections
- Vaccinia infections
- Fungal eye infections
- Mycobacterial eye infections
The steroid in Zylet can make some of these infections worse or harder to treat.
Delayed Healing
The corticosteroid in Zylet can slow healing in the eye.
This is especially important after eye surgery or in people with thinning of the cornea or sclera.
Rarely, thinning of these tissues can increase the risk of perforation.
Risk of Secondary Eye Infections
Using corticosteroid eye drops for a long time can weaken the eye’s normal defenses.
This may increase the risk of developing a new bacterial or fungal infection.
Contact your healthcare provider if your symptoms become worse or new discharge, pain, or redness develops.
Allergic Reactions
Zylet contains tobramycin, an aminoglycoside antibiotic.
Tell your healthcare provider if you have had a serious allergic reaction to tobramycin or another aminoglycoside antibiotic.
Seek medical attention if you develop severe swelling, rash, itching, or difficulty breathing.
Burning, Stinging, or Eye Irritation
Zylet may cause temporary:
- Burning
- Stinging
- Redness
- Eye irritation
- Blurred vision
These effects may improve after the drops are applied.
Contact your healthcare provider if they are severe or persistent.
Driving and Operating Machinery
Your vision may be temporarily blurred after using Zylet.
Wait until your vision is clear before driving, operating machinery, or doing anything that requires clear eyesight.
Contact Lenses
Contact lenses should generally not be worn while you have an active eye infection or inflammation unless your eye-care professional specifically tells you it is safe.
Follow your healthcare provider’s instructions about when you can start wearing contact lenses again.
Keep the Bottle Tip Clean
Do not let the dropper tip touch your eye, eyelid, fingers, or another surface.
Touching the tip can contaminate the bottle and increase the risk of an eye infection.
Pregnancy
Tell your healthcare provider if you are pregnant or planning to become pregnant.
Your healthcare provider will consider the expected benefits and possible risks before recommending Zylet.
Breastfeeding
Tell your healthcare provider if you are breastfeeding.
Your healthcare provider will decide whether Zylet is appropriate based on your treatment needs and the potential risks to your baby.
Using Other Eye Medications
Tell your healthcare provider about all other eye drops, ointments, and medications you use.
If you need more than one eye medication, your healthcare provider or pharmacist can tell you how long to wait between each product.
When to Contact Your Healthcare Provider
Contact your healthcare provider if your eye pain, redness, swelling, discharge, or vision problems become worse or do not improve.
Do not continue or refill Zylet for longer than prescribed without having your eyes re-examined.
