Pharmacist-reviewed drug information from the RxWiki encyclopedia.

Overview

Ketorolac is a prescription medication used for the short-term treatment (up to 5 days) of moderately severe pain following surgery. It is also used for back pain, cancer pain, and pain caused by kidney stones. Ketorolac ophthalmic solution is used to treat itchy eyes caused by allergies and swelling and redness (inflammation) that can occur after cataract surgery. 

Ketorolac belongs to a group of drugs called nonsteroidal anti-inflammatory drugs (NSAIDs). It works by stopping the body's production of a substance that causes pain, fever, and inflammation.

This medication comes in tablet, injectable (intravenous or intramuscular), nasal spray, and ophthalmic solution forms. Ketorolac ophthalmic solution can be taken for up to 2 weeks after cataract surgery.

The side effects you can expect depend upon which form you are taking. For instance, the ophthalmic solution may cause burning and stinging of the eyes and blurry vision. Ketorolac nasal spray may cause nasal pain and discomfort, tearing, runny nose and throat irritation.

Ketorolac tablets may cause drowsiness, dizziness and headache. Do not drive or operate heavy machinery until you know how it affects you.

Warnings

WARNING

Ketorolac tromethamine, a nonsteroidal anti-inflammatory drug (NSAID), is indicated for the short-term (up to 5 days) management of moderately severe acute pain that requires analgesia at the opioid level. It is NOT indicated for minor or chronic painful conditions. Ketorolac tromethamine is a potent NSAID analgesic, and its administration carries many risks. The resulting NSAID-related adverse events can be serious in certain patients for whom ketorolac tromethamine is indicated, especially when the drug is used inappropriately. Increasing the dose of ketorolac tromethamine beyond the label recommendations will not provide better efficacy but will result in increasing the risk of developing serious adverse events.

Gastrointestinal Effects

  • Ketorolac tromethamine can cause peptic ulcers, gastrointestinal bleeding, and/or perforation. Therefore, ketorolac tromethamine is CONTRAINDICATED in patients with active peptic ulcer disease, in patients with recent gastrointestinal bleeding or perforation, and in patients with a history of peptic ulcer disease or gastrointestinal bleeding.

Renal Effects

  • Ketorolac tromethamine is CONTRAINDICATED in patients with advanced renal impairment and in patients at risk for renal failure due to volume depletion (see WARNINGS).

Risk of Bleeding

  • Ketorolac tromethamine inhibits platelet function and is, therefore, CONTRAINDICATED in patients with suspected or confirmed cerebrovascular bleeding, patients with hemorrhagic diathesis, incomplete hemostasis, and those at high risk of bleeding.
  • Ketorolac tromethamine is CONTRAINDICATED as prophylactic analgesic before any major surgery, and is CONTRAINDICATED intra-operatively when hemostasis is critical because of the increased risk of bleeding.

Hypersensitivity

  • Hypersensitivity reactions, ranging from bronchospasm to anaphylactic shock, have occurred and appropriate counteractive measures must be available when administering the first dose of ketorolac tromethamine injection. Ketorolac tromethamine is CONTRAINDICATED in patients with previously demonstrated hypersensitivity to ketorolac tromethamine or allergic manifestations to aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs).

Intrathecal or Epidural Administration

  • Ketorolac tromethamine is CONTRAINDICATED for intrathecal or epidural administration due to its alcohol content.

Labor, Delivery and Nursing

  • The use of ketorolac tromethamine in labor and delivery is CONTRAINDICATED because it may adversely affect fetal circulation and the uterus.
  • The use of ketorolac tromethamine is CONTRAINDICATED in nursing mothers because of the potential adverse effects of prostaglandin-inhibiting drugs on neonates.

Concomitant Use with NSAIDs

  • Ketorolac tromethamine is CONTRAINDICATED in patients currently receiving ASA or NSAIDs because of the cumulative risk of inducing serious NSAID-related side effects.

DOSAGE AND ADMINISTRATION

Ketorolac Tromethamine Tablets

  • Ketorolac tromethamine tablets are indicated only as continuation therapy to ketorolac tromethamine injection, and the combined duration of use of ketorolac tromethamine injection and ketorolac tromethamine tablets is not to exceed 5 (five) days, because of the increased risk of serious adverse events.
  • The recommended total daily dose of ketorolac tromethamine tablets (maximum 40 mg) is significantly lower than for ketorolac tromethamine injection  (maximum 120 mg).

Special Populations

  • Dosage should be adjusted for patients 65 years or older, for patients under 50 kg (110 lbs) of body weight, and for patients with moderately elevated serum creatinine. Doses of ketorolac tromethamine injection are not to exceed 60 mg (total dose per day) in these patients.

Pregnancy

Tell your doctor if you are pregnant or plan to become pregnant.

The FDA categorizes medications based on safety for use during pregnancy. Five categories - A, B, C, D, and X, are used to classify the possible risks to an unborn baby when a medication is taken during pregnancy.

Ketorolac falls into category C. In animal studies, pregnant animals were given this medication and had some babies born with problems. No well-controlled studies have been done in humans. Therefore, this medication may be used if the potential benefits to the mother outweigh the potential risks to the unborn child.

Breastfeeding

Tell your doctor if you are breastfeeding or plan to breastfeed.

Ketorolac passes into human milk. Because this medication may cause harm to the baby, ketorolac should not be used while nursing.
