Carefully consider the potential benefits and risks of Flogen, Flogen, ANAPROX, ANAPROX DS or Flogen Suspension and other treatment options before deciding to use Flogen, Flogen, ANAPROX, ANAPROX DS or Flogen Suspension. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals.
Flogen as Flogen, Flogen, ANAPROX, ANAPROX DS or Flogen Suspension is indicated:
- For the relief of the signs and symptoms of rheumatoid arthritis
- For the relief of the signs and symptoms of osteoarthritis
- For the relief of the signs and symptoms of ankylosing spondylitis
- For the relief of the signs and symptoms of juvenile arthritis
Flogen as Flogen Suspension is recommended for juvenile rheumatoid arthritis in order to obtain the maximum dosage flexibility based on the patient's weight.
Flogen as Flogen and Flogen Suspension is also indicated:
- For relief of the signs and symptoms of tendonitis
- For relief of the signs and symptoms of bursitis
- For relief of the signs and symptoms of acute gout
- For the management of pain
- For the management of primary dysmenorrhea
Flogen is not recommended for initial treatment of acute pain because the absorption of Flogen is delayed compared to absorption from other Flogen-containing products.
Flogen is a nonsteroidal anti-inflammatory drug (NSAID). Flogen works by reducing hormones that cause inflammation and pain in the body.
Flogen is used to treat pain or inflammation caused by conditions such as arthritis, ankylosing spondylitis, tendinitis, bursitis, gout, or menstrual cramps.
The delayed-release or extended-release tablets are slower-acting forms of Flogen that are used only for treating chronic conditions such as arthritis or ankylosing spondylitis. These forms of Flogen will not work fast enough to treat acute pain.
Flogen may also be used for purposes not listed in this medication guide.

Use Flogen sustained-release tablets as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- Flogen sustained-release tablets comes with an extra patient information sheet called a Medication Guide. Read it carefully. Read it again each time you get Flogen sustained-release tablets refilled.
- Swallow Flogen sustained-release tablets whole. Do not break, crush, or chew before swallowing.
- Take Flogen sustained-release tablets by mouth. It may be taken with food if it upsets your stomach. Taking it with food may not lower the risk of stomach or bowel problems (eg, bleeding, ulcers). Talk with your doctor or pharmacist if you have persistent stomach upset.
- Take Flogen sustained-release tablets with a full glass of water (8 oz [240 mL]) as directed by your doctor.
- If you take antacids, cholestyramine, or sucralfate, ask your doctor or pharmacist how to take them with Flogen sustained-release tablets.
- If you miss a dose of Flogen sustained-release tablets and you are taking it regularly, take it as soon as possible. If it is almost time for your next dose, skip the missed dose. Go back to your regular dosing schedule. Do not take 2 doses at once.
Ask your health care provider any questions you may have about how to use Flogen sustained-release tablets.
There are specific as well as general uses of a drug or medicine. A medicine can be used to prevent a disease, treat a disease over a period or cure a disease. It can also be used to treat the particular symptom of the disease. The drug use depends on the form the patient takes it. It may be more useful in injection form or sometimes in tablet form. The drug can be used for a single troubling symptom or a life-threatening condition. While some medications can be stopped after few days, some drugs need to be continued for prolonged period to get the benefit from it.Flogen 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). It works by blocking your body's production of certain natural substances that cause inflammation.
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.
This form of Flogen is absorbed slowly and should not be used for pain that needs quick relief (such as during a gout attack). Ask your doctor or pharmacist about using a different form of this drug or other medications for quick relief of pain.
How to use Flogen
Read the Medication Guide provided by your pharmacist before you start using Flogen and each time you get a refill. If you have any questions, ask your doctor or pharmacist.
Take this medication by mouth as directed by your doctor, usually twice daily with or without food. Swallow this medication whole. Do not break, crush, or chew the tablets. Doing so can release the drug too quickly, increasing the risk of side effects. Take this medication with a full glass of water (8 ounces/240 milliliters) unless your doctor directs you otherwise. Do not lie down for at least 10 minutes after taking this drug.
The dosage is based on your medical condition and response to treatment. To reduce your risk of stomach bleeding and other side effects, take this medication at the lowest effective dose for the shortest possible time. Do not increase your dose or take this drug more often than directed. For ongoing conditions such as arthritis, continue taking this medication as directed by your doctor.
For certain conditions (such as arthritis), it may take up to two weeks of taking this drug regularly until you get the full benefit.
Tell your doctor if your condition does not improve or if it worsens.

What other drugs will affect Flogen?
The use of NSAIDs in patients who are receiving ACE inhibitors may potentiate renal disease states.
In vitro studies have shown that Flogen anion, because of its affinity for protein, may displace from their binding sites other drugs which are also albumin-bound.
Theoretically, the Flogen anion itself could likewise be displaced. Short-term controlled studies failed to show that taking the drug significantly affects prothrombin times when administered to individuals on coumarin-type anticoagulants. Caution is advised nonetheless, since interactions have been seen with other nonsteroidal agents of this class. Similarly, patients receiving the drug and a hydantoin, sulfonamide or sulfonylurea should be observed for signs of toxicity to these drugs.
Concomitant administration of Flogen and aspirin is not recommended because Flogen is displaced from its binding sites during the concomitant administration of aspirin, resulting in lower plasma concentrations and peak plasma levels.
The natriuretic effect of furosemide has been reported to be inhibited by some drugs of this class. Inhibition of renal lithium clearance leading to increases in plasma lithium concentrations has also been reported. Flogen and other NSAIDs can reduce the antihypertensive effect of propranolol and other beta-blockers.
Probenecid given concurrently increases Flogen anion plasma levels and extends its plasma half-life significantly.
Caution should be used if Flogen is administered concomitantly with methotrexate. Flogen, Flogen and other NSAIDs have been reported to reduce the tubular secretion of methotrexate in an animal model, possibly increasing the toxicity of methotrexate.
Drug/Laboratory Test Interactions
Flogen may decrease platelet aggregation and prolong bleeding time. This effect should be kept in mind when bleeding times are determined. The administration of Flogen may result in increased urinary values for 17-ketogenic steroids because of an interaction between the drug and/or its metabolites with m-dinitrobenzene used in this assay. Although 17-hydroxy-corticosteroid measurements (Porter-Silber test) do not appear to be artifactually altered, it is suggested that therapy with Flogen be temporarily discontinued 72 hours before adrenal function tests are performed if the Porter-Silber test is to be used.
Flogen may interfere with some urinary assays of 5-hydroxy indoleacetic acid (5HIAA).

What are the possible side effects of Flogen?
Adverse reactions reported in controlled clinical trials in 960 patients treated for rheumatoid arthritis or osteoarthritis are listed below. In general, reactions in patients treated chronically were reported 2 to 10 times more frequently than they were in short-term studies in the 962 patients treated for mild to moderate pain or for dysmenorrhea. The most frequent complaints reported related to the gastrointestinal tract.
A clinical study found gastrointestinal reactions to be more frequent and more severe in rheumatoid arthritis patients taking daily doses of 1500 mg Flogen compared to those taking 750 mg Flogen.
In controlled clinical trials with about 80 pediatric patients and in well-monitored, open-label studies with about 400 pediatric patients with juvenile arthritis treated with Flogen, the incidence of rash and prolonged bleeding times were increased, the incidence of gastrointestinal and central nervous system reactions were about the same, and the incidence of other reactions were lower in pediatric patients than in adults.
In patients taking Flogen in clinical trials, the most frequently reported adverse experiences in approximately 1% to 10% of patients are:
