Are there any other precautions or warnings for this medication?
Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Allergies: If you are allergic to acetylsalicylic acid (ASA) or other nonsteroidal anti-inflammatory drugs (e.g., ibuprofen, naproxen) you may also be allergic to ketorolac eye drops. If you are allergic to these medications, talk to your doctor before using ketorolac eye drops.
Bleeding: If you are having surgery and bleed easily or are taking medications that prolong bleeding (e.g., warfarin), discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.
Inflammation of the cornea: As with other anti-inflammatory eye drops, ketorolac can cause irritation and damage to the cornea (keratitis). In severe cases, this can lead to permanent vision problems or blindness. If you experience unusual pain, the sensation of something in your eye, unusual sensitivity to sunlight or other changes to your eye, contact your doctor immediately.
This may be more likely to occur if you have diabetes, other eye conditions such as dry eye syndrome, rheumatoid arthritis, or repeat eye surgeries during short period of time.
Vision: This medication can cause blurred or reduced vision. If you experience these symptoms, do not drive or operate machinery until these symptoms resolve. Although these symptoms usually improve over time, stop using the eye drops and contact your eye doctor if they persist.
Wound healing: Ketorolac eye drops may slow or delay the healing of wounds. You are at an increased risk if you have complicated eye surgeries, disorders of the cornea, diabetes, rheumatoid arthritis, or several eye surgeries in a short time. Talk to your doctor if you have any concerns.
Pregnancy: Ketorolac eye drops are not recommended for use during pregnancy, labour, or delivery.
Breast-feeding: This medication passes into breast milk. If you are breast-feeding and are using ketorolac eye drops it may affect your baby. Talk to your doctor about whether you should continue breast-feeding. Ketorolac eye drops are not recommended if you are breast-feeding.
Children: The safety and effectiveness of using this medication have not been established for children under the age of 18 years.
What other drugs could interact with this medication?
There may be an interaction between ketorolac eye drops and any of the following:

- prostaglandin eye drops (e.g., bimatoprost, latanoprost, travoprost)
If you are taking any of these medications, speak with your doctor or pharmacist. Depending on your specific circumstances, your doctor may want you to:
- stop taking one of the medications,
- change one of the medications to another,
- change how you are taking one or both of the medications, or
- leave everything as is.
An interaction between two medications does not always mean that you must stop taking one of them. Speak to your doctor about how any drug interactions are being managed or should be managed.
Medications other than those listed above may interact with this medication. Tell your doctor or prescriber about all prescription, over-the-counter (non-prescription), and herbal medications you are taking. Also tell them about any supplements you take.
