Nalfon

GENERIC NAME(S): FENOPROFEN CALCIUM

WARNINGS:

Nonsteroidal anti-inflammatory drugs (including fenoprofen) may rarely increase the risk for a heart attack or stroke. The risk may be greater if you have heart disease or increased risk for heart disease (for example, due to smoking, family history of heart disease, or conditions such as high blood pressure or diabetes), or with longer use. This drug should not be taken right before or after heart bypass surgery (CABG).

Also, this drug may infrequently cause serious (rarely fatal) bleeding from the stomach or intestines. This effect can occur without warning symptoms at any time while taking this drug. Older adults may be at higher risk for this effect. (See also Precautions and Drug Interactions sections.)

Stop taking fenoprofen and get medical help right away if you notice any of the following rare but serious side effects: bloody or black/tarry stools, persistent stomach/abdominal pain, vomit that looks like coffee grounds, chest/jaw/left arm pain, shortness of breath, unusual sweating, weakness on one side of the body, sudden vision changes, slurred speech.

Talk with your doctor or pharmacist about the risks and benefits of treatment with this medication.

Uses

Fenoprofen is used to relieve mild to moderate pain from various conditions. It also reduces pain, swelling, and joint stiffness from arthritis. This medication is known as a nonsteroidal anti-inflammatory drug (NSAID).

If you are treating a chronic condition such as arthritis, ask your doctor about non-drug treatments and/or using other medications to treat your pain. See also Warning section.

OTHER USES: This section contains uses of this drug that are not listed in the approved professional labeling for the drug but that may be prescribed by your health care professional. Use this drug for a condition that is listed in this section only if it has been so prescribed by your health care professional.

This medication may also be used to treat gout attacks.

How to use Nalfon

Read the Medication Guide provided by your pharmacist before you start using fenoprofen and each time you get a refill. If you have any questions regarding the information, consult your doctor or pharmacist.

Take this medication by mouth with a full glass of water (8 ounces or 240 milliliters), unless your doctor directs you otherwise. Do not lie down for at least 10 minutes after taking this drug. If stomach upset occurs while taking this medication, take it with food, milk, or an antacid.

Dosage is based on your medical condition and response to therapy. Do not take more than 3,200 milligrams in any 24-hour period. To minimize side effect risks (e.g., stomach bleeding), use this medication at the lowest effective dose for the shortest possible length of time. Do not increase your dose or take it more frequently than prescribed. For chronic conditions such as arthritis, continue taking it as directed by your doctor. Discuss the risks and benefits with your doctor or pharmacist.

In certain conditions (e.g., arthritis), it may take up to 2-3 weeks when this drug is taken regularly before you notice the full benefits.

If you are taking this drug on an "as needed" basis (not on a regular schedule), remember that pain medications work best if they are used as the first signs of pain occur. If you wait until the pain has significantly worsened, the medicine may not work as well.

Inform your doctor if your condition persists or worsens.

Side Effects

Upset stomach, gas, constipation, diarrhea, nausea, vomiting, headache, drowsiness, or dizziness may occur. If any of these effects persist or worsen, notify your doctor or pharmacist promptly.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor immediately if any of these unlikely but serious side effects occur: stomach pain, swelling of the hands or feet, sudden or unexplained weight gain, vision changes, hearing changes (e.g., ringing in the ears), mental/mood changes, fast/pounding heartbeat, persistent/severe headache, fainting, difficult/painful swallowing, unusual tiredness.

Tell your doctor immediately if any of these rare but very serious side effects occur: change in the amount of urine, frothy or pink urine, frequent/burning/painful urination, signs of infection (e.g., fever, persistent sore throat), easy bruising or bleeding, unexplained stiff neck.

This drug may rarely cause serious (possibly fatal) liver disease. If you notice any of the following highly unlikely but very serious side effects, stop taking fenoprofen and consult your doctor or pharmacist immediately: yellowing eyes or skin, dark urine, severe stomach/abdominal pain, persistent nausea/vomiting.

A very serious allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs. Symptoms of a serious allergic reaction may include: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

This is not a complete list of possible side effects. If you notice other effects not listed above, contact your doctor or pharmacist.

Precautions

Before taking fenoprofen, tell your doctor or pharmacist if you are allergic to it; or to aspirin or other NSAIDs (e.g., ibuprofen, naproxen, celecoxib); or if you have any other allergies. This product may contain inactive ingredients, which can cause allergic reactions or other problems. Talk to your pharmacist for more details.

This medication should not be used if you have certain medical conditions. Before using this medicine, consult your doctor or pharmacist if you have: severe kidney disease, aspirin-sensitive asthma (a history of worsening breathing with runny/stuffy nose after taking aspirin or other NSAIDs), recent heart bypass surgery (CABG).

Before using this medication, tell your doctor or pharmacist your medical history, especially of: liver disease, poorly controlled diabetes, stomach/intestine/esophagus problems (e.g., bleeding, ulcers, recurring heartburn), heart disease (e.g., history of heart attack), stroke, high blood pressure, swelling (edema, fluid retention), blood disorders (e.g., anemia), bleeding or clotting problems, asthma, growths in the nose (nasal polyps).

Kidney problems can sometimes occur with the use of NSAID medications, including fenoprofen. Problems are more likely to occur if you are dehydrated, have heart failure or kidney disease, are an older adult, or if you take certain medications (see also Drug Interactions section). Drink plenty of fluids as directed by your doctor to prevent dehydration and tell your doctor right away if you have any unusual change in the amount of urine.

Before having surgery, tell your doctor or dentist that you are taking this medication.

This drug may make you dizzy or drowsy. Do not drive, use machinery, or do any activity that requires alertness until you are sure you can perform such activities safely.

This medicine may cause stomach bleeding. Daily use of alcohol and tobacco, especially when combined with this medicine, may increase your risk for stomach bleeding. Limit alcohol and stop smoking. Consult your doctor or pharmacist for more information.

This medication may make you more sensitive to the sun. Avoid prolonged sun exposure, tanning booths or sunlamps. Use a sunscreen and wear protective clothing when outdoors.

Older adults may be more sensitive to the side effects of this drug, especially stomach/intestinal bleeding, kidney problems, and worsening heart problems.

Before using this medication, women of childbearing age should talk with their doctor(s) about the benefits and risks (such as miscarriage). Tell your doctor if you are pregnant or if you plan to become pregnant. During pregnancy, this medication should be used only when clearly needed. It is not recommended for use during the first and last trimesters of pregnancy due to possible harm to the unborn baby and interference with normal labor/delivery.

This drug passes into breast milk. Consult your doctor before breast-feeding.

Interactions

Your healthcare professionals (e.g., doctor or pharmacist) may already be aware of any possible drug interactions and may be monitoring you for it. Do not start, stop, or change the dosage of any medicine before checking with them first.

This drug should not be used with the following medication because very serious interactions may occur: cidofovir.

If you are currently using any of these medications listed above, tell your doctor or pharmacist before starting fenoprofen.

Before using this medication, tell your doctor or pharmacist of all prescription and nonprescription/herbal products you may use, especially of: aliskiren, ACE inhibitors (such as captopril, lisinopril), angiotensin II receptor blockers (such as losartan, valsartan), corticosteroids (e.g., prednisone), cyclosporine, desmopressin, lithium, methotrexate, pemetrexed, probenecid, "water pills" (diuretics such as furosemide).

This medication may increase the risk of bleeding when taken with other drugs that also may cause bleeding. Examples include anti-platelet drugs such as clopidogrel, "blood thinners" such as dabigatran/enoxaparin/warfarin, among others.

Check all prescription and nonprescription medicine labels carefully since many medications contain pain relievers/fever reducers (aspirin, NSAIDs such as celecoxib, ibuprofen, or ketorolac). These drugs are similar to fenoprofen and may increase your risk of side effects if taken together. However, if your doctor has directed you to take low-dose aspirin to prevent heart attack or stroke (usually at dosages of 81-325 milligrams a day), you should continue taking the aspirin unless your doctor instructs you otherwise. Ask your doctor or pharmacist for more details.

This product can affect the results of certain lab tests (thyroid hormone tests). Make sure laboratory personnel and your doctors know you use this drug.

This document does not contain all possible interactions. Therefore, before using this product, tell your doctor or pharmacist of all the products you use. Keep a list of all your medications with you, and share the list with your doctor and pharmacist.

Notes
