Toradol side effects: what you need to know

Toradol (ketorolac) is a strong NSAID doctors use for short-term moderate to severe pain. It works fast, but it’s not for long-term use. Many people get quick pain relief without trouble, yet Toradol can cause both mild and serious side effects. Knowing what to watch for keeps you safer.

Common, usually mild side effects

Some reactions are common and often go away as the drug leaves your system. Expect possible stomach upset, heartburn, nausea, headache, dizziness, drowsiness, or a feeling of being bloated. You might notice mild swelling in hands or feet. These are uncomfortable but usually not dangerous. If they bother you, tell your doctor — they may lower the dose or stop the medicine.

Because Toradol reduces inflammation and pain, it can also make you bruise more easily. If you’re taking other drugs that thin the blood, that risk rises. Don’t ignore unusual bruising or longer bleeding from small cuts.

Serious risks — how to spot them

Toradol increases the chance of stomach ulcers, internal bleeding, and kidney problems. Watch for sharp belly pain, bloody or black stools, or vomit that looks like coffee grounds — these can be signs of internal bleeding and need immediate care. Also pay attention to reduced urine output, swelling that gets worse, sudden tiredness, or shortness of breath; these can signal kidney trouble or heart strain.

Allergic reactions can happen. Get emergency help if you have swelling of the face, lips, tongue, trouble breathing, or a severe rash. Some people may experience severe skin reactions — stop the drug and seek urgent care if skin peels or blisters.

Toradol is usually limited to a short course — typically no more than five days total. Longer use drastically raises the risk of dangerous bleeding and kidney damage. If a provider suggests continuing pain control beyond a few days, ask about safer alternatives.

Certain people should avoid Toradol: anyone with active stomach ulcers or recent bleeding, serious kidney disease, advanced heart disease, or those about to have major surgery. It’s not recommended during the third trimester of pregnancy. Older adults and dehydrated patients are at higher risk for kidney and bleeding problems and may need a different pain plan.

Drug interactions matter. Don’t combine Toradol with other NSAIDs, blood thinners (warfarin, DOACs), or high-dose aspirin. Some antidepressants (SSRIs/SNRIs) and methotrexate can increase bleeding risk when taken with NSAIDs. Always tell your doctor and pharmacist every medicine and supplement you take.

If you notice worrying signs — black stools, fainting, severe belly pain, swelling, breathing trouble, or an allergic reaction — stop the medicine and get medical help right away. For mild side effects, contact your prescriber to discuss stopping the drug or switching to a safer option. Using Toradol smartly — short term, under supervision, and with awareness of risks — gives you pain relief with fewer surprises.
