A Toradol (ketorolac) shot can be given once every 6 hours, with a hard limit of 5 total days of use. That 5-day cap includes any combination of injections and oral tablets, and the FDA treats it as a firm ceiling rather than a suggestion. Toradol is one of the strongest non-opioid pain relievers available, but its power comes with risks that make it strictly a short-term drug.
Dosing Frequency and Daily Limits
The standard interval between Toradol shots is every 6 hours, whether given into a muscle (IM) or into a vein (IV). For adults under 65, each dose is 30 mg, with a maximum of 120 mg in a 24-hour period. That works out to four shots per day at most.
If the pain breaks through before those 6 hours are up, the FDA labeling is explicit: do not increase the dose or shorten the interval. The drug’s side effects scale directly with both dose and duration, so the response to inadequate pain control is adding a different type of pain reliever, not more ketorolac.
Lower Doses for Some Groups
Three groups get half the standard dose: people 65 and older, anyone with reduced kidney function, and those who weigh less than 110 pounds. For these patients, each shot drops to 15 mg every 6 hours, capping at 60 mg per day. The 5-day maximum still applies. The reduced dose reflects the fact that the drug clears more slowly in older adults and in kidneys that are already under strain, so the same amount builds to higher levels in the body.
The 5-Day Maximum
The total combined duration of Toradol use, injections and oral tablets together, cannot exceed 5 days. This is part of the drug’s boxed warning, the most serious safety alert the FDA issues. Many people receive Toradol as a single shot in an emergency room or urgent care visit and never need a second dose. When it’s used over multiple days, the clock starts with the first injection and counts every form of the drug toward that 5-day window.
This isn’t a guideline that gets relaxed for severe pain. The incidence and severity of complications rise with each additional day of use, which is why ketorolac occupies a unique position among anti-inflammatory drugs: it’s potent enough to match morphine for certain types of pain, but too risky to use beyond a handful of days.
Why Toradol Has Such Strict Limits
Toradol carries risks across three major systems, and all three get worse the longer you use it.
Stomach and intestinal bleeding. Ketorolac can cause peptic ulcers, gastrointestinal bleeding, and perforation of the stomach or intestinal wall, all of which can be fatal. These events can happen without any warning symptoms. Only about one in five people who develop a serious upper GI event from this class of drug has symptoms beforehand.
Kidney damage. The drug can cause acute kidney failure, inflammation of the kidneys, and other forms of renal injury. It’s completely off-limits for anyone with advanced kidney disease or who is dehydrated, because the combination dramatically raises the risk of kidney failure. Even in people with mildly reduced kidney function, the risks increase enough to warrant the lower dose.
Cardiovascular events. Like other drugs in its class, ketorolac raises the risk of blood clots, heart attack, and stroke. This risk climbs with longer use and is higher in people who already have heart disease or risk factors for it. Toradol is specifically prohibited for pain management after coronary artery bypass surgery.
How It Compares to Opioid Pain Relief
One reason Toradol is so widely used despite its risks is that it performs remarkably well against opioid painkillers. In studies of patients with long bone fractures, injectable ketorolac provided pain relief comparable to injectable morphine, with fewer side effects. For pain during movement, ketorolac actually outperformed morphine. Patients receiving ketorolac were 50% more likely to experience pain reduction when moving the injured limb compared to those receiving morphine.
This makes Toradol especially useful for post-surgical pain, kidney stones, migraines, and acute musculoskeletal injuries where you need strong relief but want to avoid the sedation, nausea, and addiction potential that come with opioids. The tradeoff is that this level of anti-inflammatory power can only be sustained for a few days before the risks outweigh the benefits.
What Happens After 5 Days
Once you hit the 5-day limit, your provider will transition you to a different pain management approach. This might include over-the-counter anti-inflammatories like ibuprofen or naproxen, which are less potent but safe for longer use, or other non-opioid options depending on your situation. There’s no standard waiting period defined in the labeling for when another course of ketorolac could safely begin, which is why it’s treated as a one-time, short-burst intervention rather than something you cycle on and off.
If you’ve received a single Toradol shot in an ER or clinic and are wondering when you could get another, the answer depends on context. A one-time injection for a migraine or kidney stone, followed by another single shot weeks or months later for a separate episode, is a common and generally accepted use pattern. What the 5-day rule prevents is continuous or near-continuous use for ongoing pain.
