A generic drug is a copy of the brand-name drug with the same dosage, safety, strength, quality, consumption method, performance, and intended use. Before generics become available on the market, the generic company must prove it has the same active ingredients as the brand-name drug and works in the same way and in the same amount of time in the body.
The only differences between generics and their brand-name counterparts is that generics are less expensive and may look slightly different (eg. different shape or color), as trademarks laws prevent a generic from looking exactly like the brand-name drug.
Generics are less expensive because generic manufacturers don't have to invest large sums of money to develop a drug. When the brand-name patent expires, generic companies can manufacture a copy of the brand-name and sell it at a substantial discount.
Ketorolac is used for the short-term treatment of moderate to severe pain in adults. It is usually used before or after medical procedures or after surgery. Reducing pain helps you recover more comfortably so that you can return to your normal daily activities. This medication is a nonsteroidal anti-inflammatory drug (NSAID). It works by blocking your body's production of certain natural substances that cause inflammation. This effect helps to decrease swelling, pain, or fever.Ketorolac should not be used for mild or long-term painful conditions (such as arthritis).
Read the Medication Guide and, if available, the Patient Information Leaflet provided by your pharmacist before you start taking ketorolac and each time you get a refill. If you have any questions, ask your doctor or pharmacist. Take this medication by mouth, usually every 4 to 6 hours with a full glass of water (8 ounces or 240 milliliters), or as directed by your doctor. Do not lie down for at least 10 minutes after taking this drug. If stomach upset occurs while taking this medication, take it with food, milk, or an antacid. Dosage is based on your medical condition and response to treatment. To reduce your risk of stomach bleeding and other side effects, take this medication at the lowest effective dose for the shortest possible time.

Do not take more than 40 milligrams in a 24-hour period. If you are taking this drug "as needed" (not on a regular schedule), remember that pain medications work best if they are used as the first signs of pain occur. If you wait until the pain has worsened, the medicine may not work as well.
Upset stomach, nausea, vomiting, constipation, diarrhea, gas, dizziness, or drowsiness may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.
