This combination product contains two medications: acetaminophen and ibuprofen. Acetaminophen belongs to the class of medications called analgesics (pain relievers) and antipyretics (fever reducers). Ibuprofen belongs to the class of medications known as nonsteroidal anti-inflammatory drugs (NSAIDs). Together they are used to treat fever and mild-to-moderate pain.

Acetaminophen is believed to work by reducing pain messages from getting through to the brain. It also works in the brain to reduce fever. Ibuprofen is believed to work by stopping the production of prostaglandins, which cause inflammation. It relieves inflammation and pain, as well as decreases fever.

Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.

Alcohol: Chronic excessive use of alcohol may increase the risk of liver damage due to acetaminophen, even when acetaminophen is used at normal doses. If you drink 3 or more alcoholic beverages per day your risk of severe or possibly fatal liver damage is increased.

Allergy: If you have had a reaction to acetylsalicylic acid (ASA) or other NSAIDs (e.g., diclofenac, ketorolac, naproxen) that included a runny nose, itchy skin rash, nasal polyps, or shortness of breath and wheezing, you should not take this medication. If you experience symptoms of a severe allergic reaction (e.g., hives; difficulty breathing; wheezing; swelling of the face, tongue, or throat), get immediate medical attention.

Aseptic meningitis: This medication can rarely cause symptoms of aseptic meningitis (inflammation or swelling of the membranes around the brain and spinal cord that is not caused by bacteria). If you have an autoimmune condition (e.g., systemic lupus erythematosus, mixed connective tissue disease), you are more at risk for developing this. If you experience symptoms such as stiff neck, severe headache, nausea, vomiting, fever, or changes in consciousness, stop taking this medication can get immediate medical attention.

Avoiding overdose:  Acetaminophen and ibuprofen are common ingredients in many non-prescription medications for cold and flu, pain, arthritis, and fever. Check the product label on all medications you are taking to make sure you are not exceeding the recommended dose of either medication. An overdose of acetaminophen can lead to potentially fatal liver damage.

Bladder problems: This medication may cause bladder pain, painful or difficult urination, or increased frequency of urination. If these symptoms occur without an explanation (e.g., infection), stop taking this medication and contact your doctor.

Blood clotting: This medication may reduce the ability of the blood to clot. If you are taking anticoagulants (e.g., warfarin, heparin) or have hemophilia or other blood disorders (e.g., low platelets), discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Blood pressure: Acetaminophen - ibuprofen may cause an increase in blood pressure, particularly for people who already have high blood pressure. If you are taking medications for blood pressure or are at risk of developing high blood pressure, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Gastrointestinal problems: People taking this medication have been known to experience stomach ulcers, perforation, and bleeding from the stomach. These complications can occur at any time and are sometimes severe enough to require immediate medical attention.

The risk of ulcers and bleeding increases for people taking higher doses of anti-inflammatory medications for longer periods of time. Stomach problems are also more likely to occur with alcohol use. Do not drink alcohol while taking this medication.

If you are prone to irritation of the stomach and intestines, particularly if you have had a stomach ulcer, bloody stools, diverticulosis, or other inflammatory disease of the stomach or intestines (such as ulcerative colitis or Crohn's disease), discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Stop taking the medication and contact your doctor immediately if you experience symptoms or signs suggestive of stomach ulcers or bleeding in the stomach (black, tarry stools). These reactions can occur at any time without warning during treatment.

Heart attack and stroke: Like other anti-inflammatory medications, acetaminophen - ibuprofen may increase the risk of heart attacks, and strokes which may be fatal. The risk is greater with higher total daily doses and taking the medication for a long period of time. If you have had a heart attack or stroke, or are at risk of a heart attack or stroke, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Heart disease: Ibuprofen can cause fluid retention, which may make symptoms of congestive heart failure worse. If you have been diagnosed with congestive heart failure, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

If you are taking low-dose ASA for heart health, discuss with your doctor whether you should use ibuprofen.

Kidney function: Long-term use of ibuprofen may lead to a higher risk of reduced kidney function. This is most common for people who already have kidney disease, liver disease, or heart failure; for people who take diuretics (water pills); and for seniors.

Decreased kidney function or kidney disease can cause acetaminophen – ibuprofen to build up in the body, causing side effects. If you have reduced kidney function or kidney disease, discuss with your doctor how this medication may affect your medical condition, how your medical condition may affect the dosing and effectiveness of this medication, and whether any special monitoring is needed.

Liver function: Acetaminophen – ibuprofen may cause severe and potentially fatal liver damage. This risk is increased when acetaminophen is used for longer than recommended or at doses higher than recommended. Alcoholism and liver diseases such as hepatitis increase this risk. The total amount of acetaminophen taken in a day from all sources should not exceed 4,000 mg.

Contact your doctor immediately if you experience symptoms of liver problems such as fatigue, feeling unwell, loss of appetite, nausea, yellowing of the skin or whites of the eyes, dark urine, pale stools, abdominal pain or swelling, and itchy skin.

Potassium levels: There is a risk of high levels of potassium in the blood for people who take NSAIDs, including ibuprofen. People most at risk are seniors; those who have conditions such as diabetes or kidney failure; and those taking beta-blockers (e.g., metoprolol), angiotensin converting enzyme (ACE) inhibitors (e.g., ramipril), or some diuretics (water pills). If you experience unexplained nausea, fatigue, muscle weakness or tingling sensations, contact your doctor as these are possible symptoms of too much potassium in the blood.

Reduced alertness/dizziness: Acetaminophen - ibuprofen may cause drowsiness, dizziness or a sensation of spinning, any of which can affect your ability to drive or operate machinery. Avoid these and other hazardous tasks until you have determined how this medication affects you.

Pregnancy: This medication should not be used during pregnancy unless the benefits outweigh the risks. If you become pregnant while taking this medication, contact your doctor immediately. Acetaminophen – ibuprofen, like other medications that contain NSAIDs, can cause kidney damage in the developing baby if it is taken during pregnancy. Ibuprofen should be avoided after 20 weeks into pregnancy and must not be taken in the last 3 months of pregnancy.

This medication may reduce your ability to become pregnant. Taking this medication while trying to become pregnant is not recommended.

Breast-feeding: This medication may pass into breast milk in small quantities. If you are breast-feeding and taking acetaminophen - ibuprofen, it may affect your baby. Talk to your doctor about whether you should continue breast-feeding.

Children: The safety and effectiveness of using this medication have not been established for children.

Seniors: Seniors may have a higher risk of side effects with this medication. The lowest effective dosage should be used under close medical supervision.
