Ketorolac Cream: Uses, Safety, and How It Works
Ketorolac cream is a topical form of ketorolac, a prescription nonsteroidal anti-inflammatory drug (NSAID). The FDA-approved ketorolac products are systemic (oral and injectable) and ophthalmic (eye drops); a topical ketorolac cream or gel is not itself an FDA-approved drug product. Instead, a compounding pharmacy prepares it to order, pursuant to a prescription, so a licensed provider is involved before anyone uses it.
Applied to one area, topical ketorolac concentrates more of the medication near the application site and less throughout the body than a swallowed pill. Topical does not mean zero systemic absorption or zero risk. The research base for topical NSAIDs as a category is encouraging, but it is broader than the evidence for any single compounded ketorolac formula, so it helps to understand what is established and what is not.
Ketorolac Cream Key Takeaways
- ·Ketorolac is a prescription NSAID. It is one of the more potent NSAIDs used in clinical settings, and every form requires a prescription.
- ·"Compounded topical ketorolac" means a licensed pharmacy prepares a cream or gel to order from a prescription. It is not a mass-manufactured, FDA-approved topical drug product.
- ·Topical delivery may be considered for localized symptoms because it concentrates medication near the application site and lowers systemic exposure compared with oral NSAIDs.
- ·Category evidence for topical NSAIDs is informative but is not the same as a clinical trial of one specific compounded ketorolac formula. Topical use lowers, but does not remove, systemic exposure and risk.
- ·A licensed provider should evaluate whether prescription ketorolac is appropriate for you before you use it.

What Is Ketorolac Cream?
Ketorolac (sometimes written ketorolac tromethamine) is a nonsteroidal anti-inflammatory drug. In hospitals and clinics it is best known in injectable and oral forms for short-term moderate to severe pain, and there is also an ophthalmic version used as eye drops. Ketorolac cream takes that same active ingredient and puts it into a topical base that is rubbed onto the skin over a painful area.
There is an important distinction in how ketorolac cream reaches you. The injectable, oral, and ophthalmic forms are FDA-approved drug products. A topical ketorolac cream or gel is typically made by a compounding pharmacy: the pharmacy mixes the medication to a prescriber's specifications for an individual patient. Compounded preparations are not the same as an FDA-approved, mass-manufactured topical drug, and formulas can differ between pharmacies.
NSAID (nonsteroidal anti-inflammatory drug). Works by reducing the chemical signals that drive inflammation and pain.
Injectable (IV/IM) and oral tablets, ophthalmic eye drops, and compounded topical cream or gel.
Injectable, oral, and ophthalmic ketorolac are FDA-approved. Topical ketorolac is compounded to order and is not a standalone FDA-approved product.
Yes, for every form. A licensed provider reviews your health history before ketorolac is prescribed.
Toradol is a familiar brand for injectable and oral ketorolac. Acular and Acuvail are ophthalmic brands. Topical versions are compounded, not branded products.
A topical option a provider may consider for localized musculoskeletal pain, alongside, not automatically above, other NSAID choices.
How Topical Ketorolac Works
Like other NSAIDs, ketorolac calms inflammation by blocking the enzymes that produce it. Applied to the skin, more of the drug stays near the area you treat.
When tissue is injured or irritated, the body makes prostaglandins. These chemical messengers drive swelling, sensitize nerves, and turn up pain at the affected site.
Ketorolac inhibits the COX-1 and COX-2 enzymes that make prostaglandins. With fewer prostaglandins, the inflammatory signaling that keeps an area painful settles down.
Applied over a painful area, a topical NSAID is absorbed through the skin into nearby tissue. More medication stays near the application site, and less circulates through the whole body, than with an oral dose. How much penetrates depends on the formulation, the dose, the area treated, and how deep the painful structure sits.
Because less drug reaches the bloodstream, topical use can lower systemic exposure compared with oral NSAIDs. It does not remove it. Some absorption still occurs, and NSAID-related effects remain possible, which is why a prescriber stays involved.
What Is Ketorolac Cream Used For?
Topical ketorolac is generally considered for localized musculoskeletal pain, where the painful tissue is close enough to the surface for a topical to reach useful concentrations.
Providers most often discuss topical NSAIDs for joint and soft-tissue pain that is focused in one area rather than spread throughout the body. Common examples include osteoarthritis of accessible joints such as the knee and hand, tendon-related pain like tennis elbow, and muscle or joint pain in the neck, shoulders, and back. For osteoarthritis of the knee and hand, the American College of Rheumatology guideline lists topical NSAIDs among recommended options.
Topical delivery tends to be a better fit when the source of pain is relatively superficial. Deeper or more widespread pain is less likely to respond to a cream alone, and may call for a different approach. If you are weighing how a topical compares with a tablet for your situation, our guide on topical versus oral NSAIDs walks through the trade-offs, and our arthritis overview covers joint-specific considerations.
Joints near the surface are a common reason providers consider a topical NSAID. Guidelines list topical NSAIDs among options for knee and hand osteoarthritis.
Tennis elbow and similar tendon-related pain sit close to the skin, so a topical can reach the area, though it manages symptoms rather than rebuilding tendon.
Muscle-related pain in superficial areas is a typical use case. Deeper spinal pain is less likely to respond to a cream by itself.
Pain focused over one accessible joint or muscle group is where a topical NSAID is most often discussed as an option.
Topical Ketorolac Evidence: What We Know
It helps to separate three different things: the evidence for topical NSAIDs as a category, what is known specifically about ketorolac, and what has not been established for any one compounded formula.
Level 1: Topical NSAIDs as a category
Good evidence, mostly from diclofenac and ketoprofen
The most established evidence is for the topical NSAID class as a whole, and most of it comes from topical diclofenac and ketoprofen. A 2016 Cochrane systematic review of topical NSAIDs for chronic musculoskeletal pain (39 trials, 10,631 participants) found that several topical NSAIDs provided useful pain relief for conditions like knee osteoarthritis (Derry et al., Cochrane 2016). On safety, a 2019 meta-analysis reported that topical NSAIDs may reduce gastrointestinal adverse effects compared with oral NSAIDs (Honvo et al., Drugs & Aging 2019), and a pharmacokinetic study found topical diclofenac produced lower systemic exposure than the same drug taken orally (Kienzler et al., 2010).
Level 2: What is known about ketorolac specifically
A potent NSAID, studied mostly in oral and injectable forms
Ketorolac itself is well characterized as a potent NSAID, but most of that evidence comes from its injectable and oral use for short-term pain, not from topical trials. As a rough sense of potency, an oral-dose comparison notes that 10 mg of oral ketorolac has produced pain relief comparable to 50 mg of oral diclofenac (StatPearls, Ketorolac). That is an oral-dose comparison and does not mean a ketorolac cream outperforms a diclofenac gel applied to the skin, where absorption and local concentrations work differently.
Level 3: What is not established
No category result substitutes for testing one exact formula
There is not a large body of head-to-head trials testing a specific compounded topical ketorolac formula against topical diclofenac for these conditions. Because compounded formulas vary by pharmacy, base, and concentration, results from the topical NSAID category, and from oral ketorolac, are informative but are not the same as a clinical trial of the exact cream you are prescribed. The reasonable takeaway is that topical ketorolac is a plausible, provider-directed option, not a proven upgrade over established topical NSAIDs.
Ketorolac Cream vs. Oral and Injectable Ketorolac
The active ingredient is the same. What changes is where the medication goes. Oral and injectable ketorolac act throughout the body and are used for short courses; a topical version keeps more of the dose near the area you treat.
Applied to the skin over a painful area. More of the dose stays local, and systemic exposure is lower than with an oral dose.
- Concentrates medication near the application site
- Lower systemic exposure than oral, not zero
- Compounded to order, no standalone FDA approval
- Self-applied at home under a prescription
Taken by mouth or given by injection. The drug circulates throughout the body, which is useful clinically but raises systemic exposure.
- FDA-approved for short-term moderate to severe pain
- Oral and injectable use is generally limited to about 5 days
- Full systemic exposure, with NSAID class risks
- Injectable forms are used in hospital and clinic settings
Because the oral and injectable forms are limited to short courses, some people and providers look to a topical option for more localized, longer-running symptoms. That is a reasonable rationale, but it is a clinical decision, not a guarantee of equal effect.
Ketorolac Cream vs. Diclofenac Gel
Topical diclofenac, sold over the counter as Voltaren, is the most studied topical NSAID. Compounded topical ketorolac is a prescription alternative. The table compares both with oral and injectable ketorolac.
Diclofenac gel has the advantage of a large, direct topical evidence base and easy over-the-counter access, and it helps many people with localized joint pain. Compounded topical ketorolac is a prescription option a provider may consider, but there is no direct topical head-to-head evidence showing it is more effective than diclofenac gel for these conditions. The honest framing is that they are different tools, and which one fits depends on your history and a prescriber's judgment.
| Consideration | Compounded Topical Ketorolac | Oral / Injectable Ketorolac | OTC Topical Diclofenac (Voltaren) |
|---|---|---|---|
| Prescription status | Prescription, compounded to order | Prescription | Available over the counter (1%) |
| Typical form | Topical cream or gel | Tablet or injection | Topical gel |
| Where it is applied or given | On the skin over the painful area | Whole-body (oral or injected) | On the skin over the painful area |
| Evidence base | Limited direct topical data; relies on NSAID-class evidence | Established for short-term pain (oral/IV) | Largest direct topical NSAID evidence base |
| Systemic exposure | Lower than oral, not zero | Full systemic exposure | Lower than oral, not zero |
| Key safety considerations | NSAID class cautions; skin reactions possible | GI, kidney, cardiovascular risk; short courses only | NSAID class cautions; skin reactions possible |
| Appropriate role | Provider-directed option for localized pain | Short-term moderate to severe pain | Accessible first option for localized pain |

Ketorolac Cream Safety and Side Effects
Topical use can lower systemic exposure compared with oral NSAIDs, but absorption and side effects are still possible. The details depend on your formulation, dose, and health history.
- Concentrates more of the dose near the area you treat
- Lower systemic exposure than an equivalent oral NSAID
- May reduce gastrointestinal adverse effects compared with oral NSAIDs
- The most common local issue is mild skin irritation at the application site
- Gastrointestinal effects, including irritation or bleeding
- Kidney and cardiovascular considerations
- Bleeding risk, especially with blood thinners
- Allergy or asthma triggered by NSAIDs or aspirin
- Pregnancy, where NSAIDs may not be appropriate
- Interactions with other medications
How much risk applies in your case depends on the formulation, the dose, how large an area you treat, how often you use it, what else you take, and your overall health history. This page is general information, not individualized medical advice. Seek urgent care for signs of a serious allergic reaction, such as swelling of the face or throat, difficulty breathing, or a spreading rash. For anything else, a licensed provider should evaluate whether prescription ketorolac is appropriate for you.
Who Should Ask a Provider Before Using Ketorolac?
Ketorolac is prescription-only for a reason: a clinician can weigh your history before you start. It is especially worth a careful conversation if any of the following apply.
- A history of stomach ulcers, gastrointestinal bleeding, or reflux
- Kidney disease, or risk factors for reduced kidney function
- Heart disease, high blood pressure, or prior cardiovascular events
- A known NSAID or aspirin allergy, or aspirin-sensitive asthma
- Use of blood thinners or other medications that affect bleeding
- Pregnancy or trying to become pregnant, where NSAIDs may not be appropriate
- Broken or infected skin over the area you would treat
None of these automatically rule out a topical NSAID, but they are the kind of details a prescriber needs in order to decide whether ketorolac, another medication, or a non-drug approach makes more sense for you.
How Ketro RX Pain Gel Is Prescribed
Ketro RX Pain Gel is one way to access compounded topical ketorolac. Here is what the process actually involves.
Ketro RX Pain Gel contains prescription ketorolac in a compounded topical formulation, developed by the same compounding team that works with professional sports organizations, including the Boston Red Sox. It is intended for localized application when a provider decides it is appropriate.
- Prescription required for every order
- A licensed provider reviews your questionnaire and history
- A US compounding pharmacy prepares approved prescriptions
- Approved prescriptions are shipped to you
- Lower systemic exposure than an oral NSAID, not zero exposure
Because it is compounded, the exact formulation is prepared for you rather than taken off a shelf. As with any NSAID, whether it is a good fit depends on the prescriber's review. If you want the science behind topical delivery in more depth, see how topical relief works.
