Summary
enoxaparin

Ketorolac (Toradol) is a strong pain reliever. It is a nonsteroidal anti-inflammatory drug (NSAID).

What It Treats
enoxaparin

ketorolac

Ketorolac is used for short-term relief of moderate to severe pain. It is often used after surgery. You should only use it for up to 5 days.

How It Works
enoxaparin

Enoxaparin works by blocking certain proteins in your blood that help clots form. This helps to prevent new clots from forming and keeps existing clots from getting bigger. It makes your blood less likely to clot.

ketorolac

Ketorolac reduces pain by blocking the production of substances called prostaglandins in the body. Prostaglandins contribute to inflammation and pain. By reducing prostaglandins, ketorolac helps to alleviate pain.

These two drugs have a known minor interaction flagged in FDA labeling, attributed to both drugs affect how your blood clots, and taking them together increases your risk of serious bleeding.. Serious warnings, pregnancy guidance, and contraindications can differ even when indications overlap.
