How do you use ketorolac tromethamine (tablets vs injection vs eye drops)?
Ketorolac tromethamine is a pain reliever in the NSAID (nonsteroidal anti-inflammatory drug) family. How you use it depends on the dosage form.
If you have tablets, you usually take them by mouth with water, exactly as prescribed, often for short-term pain control. Take it at the times your clinician gives you, and do not take extra doses to “catch up.”
If you have injection, a clinician typically administers it (for example, in a clinic or hospital). Do not self-administer unless you were trained and specifically instructed for your situation.
If you have ophthalmic (eye) ketorolac, you apply it to the affected eye(s) using sterile drops, following the exact schedule on your label or prescription. Don’t touch the dropper tip to the eye or surrounding skin.
What’s the usual dosing schedule and maximum duration?
Ketorolac is generally meant for short-term, acute pain rather than long-term treatment. Many clinicians restrict its total use time because the risk of serious side effects (especially bleeding and stomach irritation/ulcers) increases with longer use.
Follow your prescription label for the maximum number of days and the total daily dose. If you are unsure whether your plan is tablet-only, injection-only, or includes step-down dosing, confirm with your prescriber or pharmacist before taking more.
What should you not combine with ketorolac?
To reduce the risk of stomach bleeding and kidney problems, avoid combining ketorolac with other NSAIDs unless your prescriber specifically instructs it. That includes:
- ibuprofen (Advil, Motrin)
- naproxen (Aleve)
- aspirin used for pain (low-dose aspirin for heart protection may be handled differently—ask your clinician)
Be cautious with medicines that also raise bleeding risk, such as warfarin or other anticoagulants, unless your prescriber tells you the combination is appropriate.
How do you take it safely (food, alcohol, and missed dose)?
Taking ketorolac with food can reduce stomach upset for some people, but do not change your dosing plan unless your prescriber tells you to.
Avoid alcohol while taking ketorolac because it increases the chance of stomach bleeding.
If you miss a dose, take it only if it’s close to the next scheduled dose per your label instructions. Do not take two doses at once.
What side effects are most important to watch for?
Seek urgent medical help if you develop signs of serious bleeding, such as:
- black/tarry stools or vomiting blood
- severe stomach pain that doesn’t improve
Also contact your clinician promptly for:
- unusual bruising, persistent bleeding
- swelling of face/lips or trouble breathing (possible allergy)
- decreased urination or sudden fluid retention (possible kidney issues)
Who should avoid ketorolac or use it only with close supervision?
Ketorolac may not be appropriate if you have:
- a history of stomach ulcer/GI bleeding
- significant kidney disease
- NSAID allergy or aspirin-sensitive asthma
- certain bleeding disorders or are on strong blood thinners
- uncontrolled high blood pressure or severe heart disease
Pregnancy timing matters for NSAIDs, so if you might be pregnant or are trying to conceive, discuss it with your clinician before use.
Can you switch between injection and tablets?
Sometimes ketorolac therapy starts with injection and then switches to tablets (or similar step-down regimens). If that’s your situation, your total daily exposure still matters—switching forms doesn’t automatically reset your dose limits. Follow the exact conversion and maximum duration your prescriber specified.
