Sprix (Generic Ketorolac Nasal): Complete Medication Guide
Key Takeaways
Sprix is a nasal spray form of ketorolac, a nonsteroidal anti-inflammatory drug (NSAID) used for moderate to severe acute pain relief.
It works by reducing inflammation and blocking pain signals, offering faster relief than oral pain medications.
Common side effects include nasal irritation, headache, and throat discomfort.
It should not be used for more than 5 days and may interact with blood thinners and certain heart medications.
Always follow your doctor's dosage instructions and discuss your medical history before starting treatment.
Sprix (Generic Ketorolac Nasal) Overview
Sprix is the nasal spray version of ketorolac, a powerful NSAID commonly prescribed for moderate to severe acute pain. Unlike oral pain relievers that must travel through your digestive system, the nasal spray delivers medication directly through the nasal lining into your bloodstream, which means relief can arrive faster—sometimes within 15 to 30 minutes. Ketorolac works by blocking enzymes that create inflammation and pain signals in your body, making it effective for conditions like post-surgical pain, dental pain, or injury-related discomfort.
The generic version offers a cost-effective alternative to brand-name drugs while providing the same active ingredient and therapeutic benefits. This medication is intended for short-term use only—typically no more than 5 days—because longer use increases the risk of side effects. Sprix is often chosen over oral ketorolac when patients need rapid pain relief or have difficulty swallowing pills.

Side Effects
Most people tolerate Sprix well when used as directed. Side effects are usually mild and improve as your body adjusts to the medication. However, it's important to know what to watch for.
Common Side Effects
Nasal irritation or stinging: A burning sensation or irritation in the nose at the application site is very common with nasal sprays.
Headache: Some patients experience headaches, which may be related to the nasal spray application or the medication itself.
Throat discomfort: A sore or scratchy throat can occur as the medication drains from the nasal cavity.
Nausea: Mild stomach upset or nausea may develop, especially if taken without food.
Rhinitis: Inflammation of the nasal passages can cause congestion, sneezing, or a runny nose.
Dizziness: Light-headedness or mild dizziness may occur in some patients shortly after use.
Serious Side Effects
Allergic reactions: Rash, hives, swelling of the face or lips, or difficulty breathing require immediate medical attention.
Severe stomach bleeding or ulcers: NSAIDs can cause gastrointestinal bleeding, which may present as black, tarry stools or vomiting blood.
Kidney problems: Long-term or excessive use may affect kidney function; signs include changes in urination or swelling in the legs.
High blood pressure or heart problems: NSAIDs can increase blood pressure and raise the risk of heart attack or stroke in susceptible people.
Liver damage: Jaundice (yellowing of skin or eyes), dark urine, or severe abdominal pain may signal liver issues.
When to Seek Medical Attention
Stop using Sprix and contact your doctor immediately if you experience signs of an allergic reaction, severe stomach pain, vomiting blood, difficulty breathing, or chest pain. If you notice changes in your urination, significant swelling, or yellowing of the skin and eyes, seek prompt medical evaluation. Serious side effects are rare when the medication is used as prescribed for short durations, but it's important to report any concerning symptoms to your healthcare provider right away.

Drug Interactions
Ketorolac can interact with several medications and supplements, potentially affecting how well either medication works or increasing side effect risk. Always inform your doctor about all medications, vitamins, and supplements you take before using Sprix.
Blood Thinners (Warfarin, Apixaban)
NSAIDs like ketorolac may increase bleeding risk when combined with anticoagulants. This combination can raise the chance of dangerous bleeding. Your doctor may monitor you closely or suggest an alternative pain reliever.
Angiotensin-Converting Enzyme (ACE) Inhibitors
Medications like lisinopril used for blood pressure control may have reduced effectiveness when taken with ketorolac. The NSAID can also increase the risk of kidney problems. Your doctor should monitor kidney function if both medications are necessary.
Diuretics (Water Pills)
Sprix may reduce the effectiveness of diuretics like furosemide, making it harder to manage blood pressure or fluid retention. The combination also raises the risk of kidney damage. Regular monitoring may be needed if you take both drugs.
Lithium
Ketorolac can increase lithium levels in the blood, potentially causing toxicity. If you take lithium for bipolar disorder, your doctor may need to adjust your dose or monitor lithium levels more frequently while you use Sprix.
Other NSAIDs
Taking Sprix with other NSAIDs (ibuprofen, naproxen) increases the risk of stomach ulcers, bleeding, and kidney damage. Avoid combining NSAIDs unless your doctor specifically directs you to do so.
Methotrexate
This arthritis and cancer medication's effectiveness may be reduced by ketorolac, and the combination increases the risk of kidney and liver damage. Your doctor will carefully evaluate whether these medications can be used together safely.
