What is the most important information I should know about DUEXIS?

• DUEXIS can cause an increased risk of a heart attack or stroke that can lead to death. This risk may occur early in treatment and may increase with longer use and with increasing doses of medicine containing NSAIDs.
• DUEXIS can cause an increased risk of bleeding, ulcers, and tears (perforation) of the esophagus, stomach and intestines. These events can occur at any time during use, without warning symptoms and may cause death. Elderly patients and patients with a history of ulcer disease or stomach or intestine bleeding are at greater risk for getting an ulcer or bleeding.
• You should take DUEXIS exactly as prescribed, at the lowest dose possible and for the shortest time needed.

DUEXIS can cause serious side effects. Stop taking DUEXIS and call your doctor or go to your emergency department right away if you get:

• Difficulty breathing, swelling of the face or throat. These could be signs of a serious allergic reaction.
• Chest pain, shortness of breath, weakness in one part or side of your body, or slurring of speech. These could be signs of a serious blood clotting event.
• Upper stomach pain, upset stomach, black, tarry stools, or vomiting of blood. These could be signs of an esophagus, stomach, or intestinal ulcer, bleed, or tear. Note: if you are also taking low‐dose aspirin, you are at increased risk for esophagus, stomach, or intestinal bleeding.
• Nausea, more tired or weaker than usual, itching, yellowing of the skin or eyes, right upper abdomen tenderness, and “flu‐like” symptoms. These could be signs of a liver problem.
• Shortness of breath, unexplained weight gain, or swelling of the arms, legs, hands or feet. These could be signs of a serious heart problem.
• Any type of rash. This could be a sign of a serious skin reaction.

These are not all of the possible side effects of DUEXIS. Please talk to your doctor if you experience any symptoms that bother you or that do not go away. If you take too much DUEXIS, call your poison control center at 1-800-222-1222.

Who should not use DUEXIS?

Do not take DUEXIS:

• if you are allergic to ibuprofen, famotidine, any other histamine H₂–receptor blocker, or any of the ingredients in DUEXIS. See the Medication Guide for a complete list of ingredients.
• if you have had an asthma attack, hives, or other allergic reaction with aspirin or any other NSAIDs.
• right before or after heart bypass surgery called coronary artery bypass graft.
• if you are in the 30^th week of pregnancy until delivery

How should I take DUEXIS?

Take DUEXIS exactly as your health care provider tells you to take it. Do not change your dose or stop DUEXIS without first talking to your health care provider. Swallow DUEXIS tablets whole with liquid. Do not split, chew, crush, or dissolve the DUEXIS tablet. If you forget to take a dose of DUEXIS, take it as soon as you remember. If it is almost time for your next dose, do not take the missed dose. Take the next dose on time. Do not take 2 doses at one time to make up for a missed dose. You should not take an ibuprofen tablet and famotidine tablet together instead of taking a DUEXIS tablet, because they will not work in the same way.

What are the possible side effects of DUEXIS?

The most common side effects of DUEXIS include nausea, diarrhea, constipation, upper abdominal pain, and headache.

What other medications might interact with DUEXIS?

Do not use DUEXIS while taking other NSAIDs unless your health care provider says it is OK. NSAIDs may be present in over‐the‐counter medications for treatment of colds, fever, or insomnia; refer to the label of over‐the‐counter medications you are taking or ask your pharmacist. Do not use DUEXIS and low‐dose aspirin until you talk to your health care provider. Tell your health care provider about all of the medicines you take as some medicines can react with NSAIDs and cause serious side effects.

What should I tell my health care provider?

Before starting DUEXIS, tell your health care provider if you have a history of ulcer disease or esophagus, stomach, or intestine bleeding, liver or kidney problems, high blood pressure, heart problems, bleeding problems, asthma, or are pregnant, trying to become pregnant, or breast feeding. Taking DUEXIS at about 20 weeks of pregnancy or later may harm your unborn baby. If you need to take DUEXIS for more than 2 days when you are between 20 and 30 weeks of pregnancy, your healthcare provider may need to monitor the amount of fluid in your womb around your baby. You should not take DUEXIS after about 30 weeks of pregnancy. Also tell your health care provider about all of the medicines you take, including prescription or over-the-counter medicines, vitamins, or herbal supplements. Do not start taking new medicines without talking to your health care provider first.
