What Is Ketorolac? Uses, Dosage, and What You Need to Know in 2026

What Is Ketorolac?

Ketorolac is a prescription nonsteroidal anti-inflammatory drug (NSAID) used for the short-term management of moderately severe acute pain.

Sold under brand names like Toradol (oral and injection), Sprix (nasal spray), and Acular (eye drops), Ketorolac is one of the most potent NSAIDs available. Unlike over-the-counter options like Ibuprofen or Naproxen, it provides analgesia at the opioid level — making it a valuable non-narcotic option for acute pain management.

What Is Ketorolac Used For?

• Reduction of eye inflammation after cataract surgery — Using the ophthalmic form (Acular).
• Relief of eye itching from seasonal allergies — Also using the ophthalmic form.

Doctors also commonly use Ketorolac off-label for:

• Migraine treatment in the emergency department
• Kidney stone (renal colic) pain
• Postoperative pain after orthopedic or dental surgery
• Acute musculoskeletal injuries
• Sickle cell crisis pain management
• Pain management in patients with opioid use disorder (as a non-addictive alternative)

How Is Ketorolac Taken?

Ketorolac comes in several forms:

Oral Tablets (10 mg)

Oral Ketorolac should only be used as a follow-up to IV or IM injection therapy — it's not meant to be the first form you take. Take with food or milk to reduce stomach upset. Maximum dose: 40 mg per day (four 10 mg tablets).

Intramuscular (IM) Injection

Given as a shot in the muscle, typically in a hospital, ER, or clinic. Standard dose: 60 mg as a single dose, or 30 mg every 6 hours (max 120 mg/day). For patients 65 and older: max 60 mg/day.

Intravenous (IV) Injection

Given directly into a vein in a healthcare setting. Dosing is similar to IM injection. Available in 15 mg/mL and 30 mg/mL concentrations.

Nasal Spray (Sprix)

One spray (15.75 mg) in each nostril every 6-8 hours, maximum 126 mg per day. This form allows patients to self-administer outside of a clinical setting.

Eye Drops (Acular, Acular LS)

Used for eye conditions only. Applied directly to the eye as directed by your ophthalmologist.

Critical rule: The total duration of Ketorolac use across ALL forms combined must not exceed 5 days.

Who Should Not Take Ketorolac?

Ketorolac has more contraindications than most NSAIDs. You should not take it if you have:

• Active or history of peptic ulcer disease or GI bleeding
• Advanced kidney disease or risk of kidney failure
• Known allergy to Ketorolac, Aspirin, or other NSAIDs
• History of asthma or hives triggered by Aspirin or NSAIDs

• For use longer than 5 days
