Inza is a nonsteroidal anti-inflammatory drug (NSAID) used to reduce mild to moderate pain, inflammation, and fever. Inza works by blocking an enzyme that makes prostaglandin (a hormone-like substance that participates in a variety of body functions), which results in lower levels of prostaglandins in the body. Lower levels of prostaglandins reduce pain, inflammation, and fever.
Inza is prescribed to treat diseases and conditions that cause mild to moderate pain, fever, and inflammation. For example, Pain from strains and sprains; pain from cuts, scrapes, and puncture wounds; muscle aches and pains; tooth pain; common cold; mild headache; some arthritis conditions; joint pain; and to reduce fever.
Common side effects of Inza include, diarrhea, constipation, nausea, heartburn, belly pain, drowsiness, headaches, tinnitus (ringing in the ears), and mild rash.
More serious side effects and adverse effects include, increased bleeding after injury, stomach ulcers, impaired kidney function, severe allergic reaction (anaphylaxis), blood clots, heart attack, heart failure, and high blood pressure.
The maximum dose prescribed under a doctor's care is 3.2 g daily. Otherwise, the over-the-counter (OTC) maximum daily dose is 1.2 g daily. Dosage depends upon the age, weight, and any current medical conditions of the patient. Several drugs interact with Inza so check with your doctor, pharmacist, or other health care professional with questions in regard to this drug. Doctors don't know if it is safe to take Inza if your are pregnant, therefore it is not recommended if you are pregnant. According to the American Academy of Pediatrics, Inza is safe to take while breastfeeding.

10. Pregnancy and breastfeeding
Inza isn't normally recommended in pregnancy – especially if you're 30 or more weeks – unless it's prescribed by a doctor. This is because there might be a link between taking Inza in pregnancy and some birth defects, in particular damage to the baby's heart and blood vessels.
There may also be a link between taking Inza in early pregnancy and miscarriage.
Talk to your doctor about the benefits and possible harms of taking Inza. It will depend on how many weeks pregnant you are and the reason you need to take the medicine. There may be other treatments that are safer for you.
Paracetamol is the best painkiller to take during pregnancy.

People who take nonsteroidal anti-inflammatory drugs (NSAIDs) (other than aspirin) such as Inza 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 Inza 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; if you smoke; and if you have or have ever had high cholesterol, high blood pressure, 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 will be undergoing a coronary artery bypass graft (CABG; a type of heart surgery), you should not take Inza right before or right after the surgery.
NSAIDs such as Inza 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 who drink three or more alcoholic drinks per day while taking Inza. Tell your doctor if you take any of the following medications: anticoagulants ('blood thinners') such as warfarin (Coumadin, Jantoven); aspirin; other NSAIDs such as ketoprofen and naproxen (Aleve, Naprosyn); 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). Also tell your doctor if you have or have ever had ulcers, bleeding in your stomach or intestines, or other bleeding disorders. If you experience any of the following symptoms, stop taking Inza 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.
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 Inza. 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 prescription Inza 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 (http://www.fda.gov/Drugs/DrugSafety/ucm085729.htm) or the manufacturer's website to obtain the Medication Guide.
Serious allergic reaction
In rare cases, it's possible to have a serious allergic reaction to Inza.
The active ingredient in Aleve is naproxen and the other ingredient is sodium. For every 200mg of naproxen, Aleve contains 20mg sodium.
The active ingredient in Advil is Inza. Advil also contains sodium because the manufacturer claims that sodium Inza is more soluble in water than standard Inza.
Data suggest that Inza may confer an increased risk of thrombotic and congestive heart failure (CHF) events relative to lumiracoxib among aspirin users at high cardiovascular risk. The study indicates that naproxen may be associated with lower risk relative to lumiracoxib among non-aspirin users.
Allergy alert: Inza may cause a severe allergic reaction, especially in people allergic to aspirin. Symptoms may include:
If an allergic reaction occurs, stop use and seek medical help right away.

2. Key facts
- Inza takes 20 to 30 minutes to work if you take it by mouth. It takes 1 to 2 days to work if you put it on your skin.
- Inza works by reducing hormones that cause pain and swelling in the body.
- For strains and sprains, some doctors and pharmacists recommend waiting 48 hours before taking Inza as it may slow down healing. If you're unsure speak to a pharmacist.
- Inza is typically used for period pain or toothache. Some people find Inza better than paracetamol for back pain.
- Always take Inza tablets and capsules with food or a drink of milk to reduce the chance of an upset stomach. Do not take it on an empty stomach.
- If you're taking tablets, take the lowest dose for the shortest time. Do not use it for more than 10 days unless you've spoken to your doctor. Do not use the gel, mousse or spray for more than 2 weeks without talking to your doctor.
- Inza is called by different brand names, including Nurofen, Brufen and Calprofen (syrup). Inza gel can be called Fenbid, Ibugel and Ibuleve.
Which drugs or supplements interact with Inza?
Inza is associated with several suspected or probable interactions that can affect the action of other drugs.
- Inza may increase the blood levels of lithium (Eskalith, Lithobid) by reducing the excretion of lithium by the kidneys. Increased levels of lithium may lead to lithium toxicity.
- Inza may reduce the blood pressure-lowering effects of drugs that are given to reduce blood pressure. This may occur because prostaglandins play a role in the regulation of blood pressure.
- When Inza is used in combination with methotrexate (Rheumatrex, Trexall) or aminoglycosides (for example, gentamicin) the blood levels of the methotrexate or aminoglycoside may increase, presumably because their elimination from the body is reduced. This may lead to more methotrexate or aminoglycoside-related side effects.
- Inza increases the negative effect of cyclosporine on kidney function.
- Individuals taking oral blood thinners or anticoagulants, for example, warfarin (Coumadin), should avoid Inza because Inza also thins the blood, and excessive blood thinning may lead to bleeding.
- If aspirin is taken with Inza there may be an increased risk for developing an ulcer.
- Persons who have more than three alcoholic beverages per day may be at increased risk of developing stomach ulcers when taking Inza or other NSAIDs.
- Combining SSRIs or selective serotonin reuptake inhibitors (for example, fluoxetine , citalopram , paroxetine [Paxil, Paxil CR, Pexeva) with NSAIDs may increase the likelihood of upper gastrointestinal bleeding.
If you get a headache, vomit or feel sleepy after accidentally swallowing Inza gel, contact a doctor or 111 straight away.
Urgent advice: Call your doctor straight away if you've taken more than the maximum dose of Inza
If you go to a hospital accident and emergency (A&E) department, do not drive yourself – get someone else to drive you or call for an ambulance.
