Ketorolac is used for the short-term relief of moderately severe pain and should not be used for longer than 5 days, for mild pain, or for pain from chronic (long-term) conditions. You will receive your first doses of ketorolac by intravenous (into a vein) or intramuscular (into a muscle) injection in a hospital or medical office. After that, your doctor may choose to continue your treatment with oral ketorolac. You must stop taking oral ketorolac on the fifth day after you received your first ketorolac injection. Talk to your doctor if you still have pain after 5 days or if your pain is not controlled with this medication. Ketorolac may cause serious side effects, especially when taken improperly. Take ketorolac exactly as directed. Do not take more of it or take it more often than prescribed by your doctor.
People who take nonsteroidal anti-inflammatory drugs (NSAIDs) (other than aspirin) such as ketorolac may have a higher risk of having a heart attack or a stroke than people who do not take these medications. These events may happen without warning and may cause death. This risk may be higher for people who take NSAIDs for a long time. Do not take an NSAID such as ketorolac if you have recently had a heart attack, unless directed to do so by your doctor. Tell your doctor if you or anyone in your family has or has ever had heart disease, a heart attack, or a stroke or 'ministroke;' if you smoke; and if you have or have ever had high cholesterol, high blood pressure, bleeding or clotting problems, or diabetes. Get emergency medical help right away if you experience any of the following symptoms: chest pain, shortness of breath, weakness in one part or side of the body, or slurred speech.
If you are having surgery, including dental surgery, tell the doctor or dentist that you are taking ketorolac. If you will be undergoing a coronary artery bypass graft (CABG; a type of heart surgery), you should not take ketorolac right before or right after the surgery.
NSAIDs such as ketorolac may cause ulcers, bleeding, or holes in the stomach or intestine. These problems may develop at any time during treatment, may happen without warning symptoms, and may cause death. The risk may be higher for people who take NSAIDs for a long time, are older in age, have poor health, or drink large amounts of alcohol while taking ketorolac. Tell your doctor if you take any of the following medications: anticoagulants ('blood thinners') such as warfarin (Coumadin, Jantoven); aspirin; oral steroids such as dexamethasone, methylprednisolone (Medrol), and prednisone (Rayos); selective serotonin reuptake inhibitors (SSRIs) such as citalopram (Celexa), fluoxetine (Prozac, Sarafem, Selfemra, in Symbyax), fluvoxamine (Luvox), paroxetine (Brisdelle, Paxil, Pexeva), and sertraline (Zoloft); or serotonin norepinephrine reuptake inhibitors (SNRIs) such as desvenlafaxine (Khedezla, Pristiq), duloxetine (Cymbalta), and venlafaxine (Effexor XR). Do not take aspirin or other NSAIDs such as ibuprofen (Advil, Motrin) and naproxen (Aleve, Naprosyn) while you are taking ketorolac. Also tell your doctor if you have or have ever had ulcers or bleeding in your stomach or intestines. If you experience any of the following symptoms, stop taking ketorolac and call your doctor: stomach pain, heartburn, vomit that is bloody or looks like coffee grounds, blood in the stool, or black and tarry stools.
Ketorolac may cause kidney failure. Tell your doctor if you have kidney or liver disease, if you have had severe vomiting or diarrhea or think you may be dehydrated, and if you are taking angiotensin-converting enzyme (ACE) inhibitors such as benazepril (Lotensin, in Lotrel), captopril, enalapril (Vasotec, in Vaseretic), fosinopril, lisinopril (in Zestoretic), moexipril (Univasc), perindopril (Aceon, in Prestalia), quinapril (Accupril, in Quinaretic), ramipril (Altace), and trandolapril (Mavik, in Tarka); or diuretics ('water pills'). If you experience any of the following symptoms, stop taking ketorolac and call your doctor: swelling of the hands, arms, feet, ankles, or lower legs; unexplained weight gain; confusion; or seizures.
Some people have severe allergic reactions to ketorolac. Tell your doctor if you are allergic to ketorolac, aspirin or other NSAIDs such as ibuprofen (Advil, Motrin) or naproxen (Aleve, Naprosyn), or any other medications. Also tell your doctor if you have or have ever had asthma, especially if you also have frequent stuffed or runny nose or nasal polyps (swelling of the lining of the nose). If you experience any of the following symptoms, stop taking ketorolac and call your doctor right away: rash; hives; itching; swelling of the eyes, face, throat, tongue, arms, hands, ankles, or lower legs; difficulty breathing or swallowing; or hoarseness.
Do not breastfeed while you are taking ketorolac.
Keep all appointments with your doctor and the laboratory. Your doctor will monitor your symptoms carefully and will probably order certain tests to check your body's response to ketorolac. Be sure to tell your doctor how you are feeling so that your doctor can prescribe the right amount of medication to treat your condition with the lowest risk of serious side effects.
Your doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with ketorolac and each time you refill your prescription. Read the information carefully and ask your doctor or pharmacist if you have any questions. You can also visit the Food and Drug Administration (FDA) website ( https://www.fda.gov/Drugs/DrugSafety/ucm085729.htm ) to obtain the Medication Guide.

- tell your doctor if you are pregnant, plan to become pregnant; or are breast-feeding. Ketorolac may harm the fetus and cause problems with delivery if it is taken around 20 weeks or later during pregnancy. Do not take ketorolac around or after 20 weeks of pregnancy, unless you are told to do so by your doctor. If you become pregnant while taking ketorolac, call your doctor.

What should I know about storage and disposal of this medication?
Keep this medication in the container it came in, tightly closed, and out of reach of children. Store it at room temperature and away from excess heat and moisture (not in the bathroom).
It is important to keep all medication out of sight and reach of children as many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and young children can open them easily. To protect young children from poisoning, always lock safety caps and immediately place the medication in a safe location – one that is up and away and out of their sight and reach. http://www.upandaway.org
Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website ( http://goo.gl/c4Rm4p ) for more information if you do not have access to a take-back program.
What other information should I know?
Do not let anyone else take your medication. Ask your pharmacist any questions you have about refilling your prescription.
It is important for you to keep a written list of all of the prescription and nonprescription (over-the-counter) medicines you are taking, as well as any products such as vitamins, minerals, or other dietary supplements. You should bring this list with you each time you visit a doctor or if you are admitted to a hospital. It is also important information to carry with you in case of emergencies.
