Ketorolac – What It Is, How It Works, and What to Watch For

When you hear about Ketorolac, a prescription NSAID used for short‑term post‑surgical pain. Also known as Toradol, it delivers fast relief by blocking prostaglandin synthesis, which cuts down inflammation and pain signals.

Ketorolac belongs to the broader class of NSAIDs, drugs that reduce fever, pain, and swelling by inhibiting cyclooxygenase enzymes. This class also includes ibuprofen and naproxen, which many people take over the counter. Knowing that Ketorolac is an NSAID helps you understand why it shares both benefits and cautions with its cousins.

The drug shines in managing postoperative pain, the acute discomfort that follows surgical procedures. Surgeons often prescribe it for up to five days because its potency can keep you moving and breathing deeply, which is crucial after abdominal or orthopedic surgery. If you’re recovering from an operation, you’ll likely hear doctors say, “We’ll start with Ketorolac to get you comfortable fast.”

However, powerful relief comes with a price. One major concern is renal impairment, reduced kidney function that can worsen when NSAIDs restrict blood flow to the kidneys. The drug’s effect on prostaglandins can lower the kidney’s ability to filter waste, especially in older adults or those taking other nephrotoxic meds. If you already have kidney issues, your doctor may skip Ketorolac or lower the dose.

Another safety flag is the risk of gastrointestinal side effects, ulcers, bleeding, and stomach irritation common to many NSAIDs. These happen because prostaglandins also protect the stomach lining. To mitigate this, clinicians often pair Ketorolac with a proton‑pump inhibitor or advise you to take it with food, even though it’s typically taken on an empty stomach for faster action.

Practical Tips and Key Facts

Think of Ketorolac as a short‑term rescue agent, not a chronic pain solution. The recommended adult dose is usually 10‑30 mg every 4‑6 hours, never exceeding 5 days. For patients under 65 with normal kidney function, the higher end of the range is safe; for seniors or those with mild kidney loss, a lower dose is wiser. Ketorolac should be avoided in pregnancy, especially after the first trimester, because it can affect fetal blood flow.

Monitoring is simple but essential: your doctor may check kidney labs and stool for hidden blood during treatment. If you notice black or tarry stools, severe stomach pain, or sudden swelling in your ankles, seek help immediately—those could be signs of bleeding or fluid retention.

Beyond human medicine, Ketorolac finds a niche in veterinary care, especially for dogs and cats recovering from surgery. The dosing differs, and a vet will adjust it based on the animal’s weight and health status.

In the end, Ketorolac offers rapid, potent pain relief when used correctly. Understanding its ties to NSAIDs, its role in postoperative care, and the kidney and stomach warnings can help you and your healthcare team decide if it’s the right choice.
