    • What is this medication and its most common uses?

      Nalfon is a medicine used to relieve mild to moderate pain. Nalfon is also used to relieve signs and symptoms of rheumatoid arthritis and osteoarthritis.

    • What should I know when beginning and continuing on this medication?

      How does this medication work?

      Nalfon is a nonsteroidal anti-inflammatory drug (NSAID) that works by blocking a natural substance in the body that is involved in causing inflammation and pain.

      What are the beneficial effects of this medication and when should I begin to have results?

      What:

      Pain: Nalfon has been shown to reduce pain intensity and increase pain relief.

      Rheumatoid Arthritis and Osteoarthritis: Nalfon has been shown to reduce pain, stiffness, and swelling associated with rheumatoid arthritis and osteoarthritis.

      When: Improvement may be seen in a few days in many patients, however an additional 2 to 3 weeks may be required to gauge the full benefits of therapy.

      How do I know it is working?

      You may feel a relief in your pain and/or arthritis symptoms after you start taking Nalfon. This is a good indicator that the medicine is working. Your healthcare provider may ask you questions to assess how well your symptoms are controlled.

    • What are the possible side effects of this medication?

      The following is not a full list of side effects. Side effects cannot be anticipated. If any develop or change in intensity, tell your healthcare provider as soon as possible. Only your healthcare provider can determine if it is safe for you to continue taking this medication.

      Nalfon may increase your chance of a life-threatening heart attack or stroke. The risk of heart attack or stroke may happen early in treatment and may increase with increasing doses of NSAIDs and with longer use of NSAIDs. Do not take Nalfon right before or after a heart surgery called a coronary artery bypass graft (CABG). Avoid taking Nalfon after a recent heart attack, unless your healthcare provider tells you to. You may have an increased risk of another heart attack if you take NSAIDs after a recent heart attack. Contact your healthcare provider right away if you have any symptoms of a heart attack or stroke, such as chest pain, shortness of breath, weakness, or slurred speech.

      Nalfon may increase your chance of bleeding, ulcers, and tears of the esophagus (tube leading from the mouth to the stomach), stomach, and intestines at any time during your treatment. Ulcers, bleeding, and tears can happen without warning symptoms and may be life threatening. Your chance of getting an ulcer or bleeding increases with past history of stomach ulcers, or stomach or intestinal bleeding with use of NSAIDs; use of steroid medicines, blood thinners, and certain antidepressant medicines; more frequent or longer use of NSAIDs; drinking alcohol; having poor health; advanced liver disease; bleeding problems; smoking; and older age. Contact your healthcare provider if you experience sudden or severe stomach pain, indigestion, or bloody diarrhea, or if you vomit blood.

      More common side effects may include: heartburn; headache; drowsiness; nausea; dizziness; constipation; nervousness; weakness; swelling of the arms, legs, hands, and feet.

      Less common side effects may include:

      Liver problems with symptoms such as nausea, tiredness, weakness, diarrhea, itching, yellowing of your skin or the whites of your eyes, right upper abdominal (stomach area) pain, and flu-like symptoms.

      Serious allergic reactions or serious skin reactions that may be life threatening, with symptoms such as skin rash, blisters with fever, trouble breathing, or swelling of your face or throat.

      Nalfon may also cause asthma attacks (in people who have asthma), new or worse high blood pressure, heart failure from body swelling (fluid retention), kidney problems, or anemia (low red blood cell counts).

    • Who should not take this medication?

      Do not take Nalfon if you are allergic to it or any of its ingredients.

      Do not take Nalfon if you have had an asthma attack, hives, or other allergic reaction with aspirin or any other NSAID (such as ibuprofen or naproxen).

      Do not take Nalfon right before or after heart bypass surgery.

    • What should I tell my healthcare provider before I take the first dose of this medication?

      Tell your healthcare provider about all prescription, over-the-counter, and herbal medications you are taking before beginning treatment with Nalfon. Also, talk to your healthcare provider about your complete medical history, especially if you have kidney or liver problems, high blood pressure, asthma, hearing problems, or a history of heart problems (including heart failure); or are pregnant, plan to become pregnant, or are breastfeeding.

    • What should I avoid while taking this medication?
