Caldolor injection is a nonsteroidal anti-inflammatory drug (NSAID). Ibuprofen works by reducing hormones that cause inflammation and pain in the body.

Caldolor injection is used to reduce fever and treat pain.

Caldolor may also be used for purposes not listed in this medication guide. Neoprofen, another brand of ibuprofen injection, is used in premature babies to treat a condition called patent ductus arteriosus (an abnormal blood vessel opening that normally closes shortly after birth).

Caldolor can increase your risk of fatal heart attack or stroke, even if you don't have any risk factors. You should not receive this medicine just before or after heart bypass surgery (coronary artery bypass graft, or CABG).

Ibuprofen may also cause stomach or intestinal bleeding, which can be fatal. These conditions can occur without warning while you are using Caldolor, especially in older adults.

Caldolor is given as an infusion into a vein. A healthcare provider will give you this injection.

Drink plenty of liquids while you are receiving Caldolor injection.

You should not be treated with Caldolor if you are allergic to ibuprofen, or if you have ever had an asthma attack or severe allergic reaction after taking aspirin or an NSAID.

To make sure Caldolor is safe for you, tell your doctor if you have:

• heart disease, high blood pressure, high cholesterol, diabetes, or if you smoke;

• a heart attack, stroke, or blood clot;

• stomach ulcers or bleeding;

• asthma;

• liver or kidney disease;

• fluid retention; or

• a connective tissue disease such as Marfan syndrome, Sjogren's syndrome, or lupus.

If you are pregnant, you should not receive Caldolor unless your doctor tells you to. Taking an NSAID during the last 20 weeks of pregnancy can cause serious heart or kidney problems in the unborn baby and possible complications with your pregnancy.

You should not breast-feed while using this medicine.

Because you will receive your injection in a clinical setting, you are not likely to miss a dose.

Since this medication is given by a healthcare professional in a medical setting, an overdose is unlikely to occur.

Avoid taking aspirin while you are receiving Caldolor.

Ask a doctor or pharmacist before using other medicines for pain, fever, swelling, or cold/flu symptoms. They may contain ingredients similar to ibuprofen (such as aspirin, ketoprofen, or naproxen).
