What is Irfen 600mg?
Irfen 600mg is a nonsteroidal anti-inflammatory drug (NSAID) used to treat mild to moderate pain, and helps to relieve symptoms of arthritis (osteoarthritis, rheumatoid arthritis, or juvenile arthritis), such as inflammation, swelling, stiffness, and joint pain. Irfen 600mg does not cure arthritis and will help you only as long as you continue to take it.
In addition, Irfen 600mg can be used to treat fever, menstrual cramps, and other conditions as determined by your doctor.
Irfen 600mg is available both over-the-counter (OTC) and with your doctor's prescription.
Irfen 600mg indications
Carefully consider the potential benefits and risks of Irfen 600mg
Oral Suspension and other treatment options before deciding to use Irfen 600mg. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals.
In Pediatric Patients, Irfen 600mg
Oral Suspension is indicated:
- For reduction of fever in patients aged 6 months up to 2 years of age.

Off Label Uses
Gout, acute flares
Clinical experience suggests the utility of Irfen 600mg as an alternative option for acute gout flares.
Based on the 2012 American College of Rheumatology guidelines for management of gout, NSAIDs are effective and recommended agents in the treatment of acute gout flares.
Pericarditis
Data from double-blind, placebo-controlled, multicenter trials indicate that colchicine in combination with aspirin or Irfen 600mg significantly reduces the incidence of symptoms at 72 hours and the risk of recurrence in acute and recurrent pericarditis. Based on Brazilian Society of Cardiology guidelines for the management of myocarditis and pericarditis and European Society of Cardiology (ESC) guidelines for the management of pericardial diseases, nonsteroidal anti-inflammatory drugs (NSAIDs) (typically, aspirin or Irfen 600mg) in combination with colchicine are recommended as first-line treatment to manage pain and resolve inflammation in idiopathic and viral acute and recurrent pericarditis.
Irfen 600mg description
Irfen 600mg is a member of the propionic acid group of nonsteroidal anti-inflammatory drugs (NSAIDs). It is a racemic mixture of [+]S- and [-]R-enantiomers.
The chemical name for Irfen 600mg is (±)-2-(4-isobutylphenyl) propionic acid. It has a molecular weight of 206.28 and a molecular formula of C13H18O2.
Irfen 600mg is a colorless, crystalline stable solid, with a melting point of 75-77°C. It is relatively insoluble in water but readily soluble in most organic solvents. Irfen 600mg has a pKa of 4.43±0.03 and an n-octanol/water partition coefficient of 11.7 at pH 7.4.
Irfen 600mg has shown analgesic, anti-inflammatory and antipyretic activity in both animal and human studies. These properties provide symptomatic relief of inflammation and pain.
Irfen 600mg dosage
2.1 Recommended Dose
A course of therapy is three doses of Irfen 600mg Lysine administered intravenously (administration via an umbilical arterial line has not been evaluated). An initial dose of 10 mg per kilogram is followed by two doses of 5 mg per kilogram each, after 24 and 48 hours. All doses should be based on birth weight. If anuria or marked oliguria (urinary output <0.6 mL/kg/hr) is evident at the scheduled time of the second or third dose of Irfen 600mg Lysine, no additional dosage should be given until laboratory studies indicate that renal function has returned to normal. If the ductus arteriosus closes or is significantly reduced in size after completion of the first course of Irfen 600mg Lysine, no further doses are necessary. If during continued medical management the ductus arteriosus fails to close or reopens, then a second course of Irfen 600mg Lysine, alternative pharmacological therapy, or surgery may be necessary.
2.2 Directions for Use
For intravenous administration only.
Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. Do not use Irfen 600mg Lysine if particulate matter is observed.
After the first withdrawal from the vial, any solution remaining must be discarded because Irfen 600mg Lysine contains no preservative.
For administration, Irfen 600mg Lysine should be diluted to an appropriate volume with dextrose or saline. Irfen 600mg Lysine should be prepared for infusion and administered within 30 minutes of preparation and infused continuously over a period of 15 minutes. The drug should be administered via the IV port that is nearest the insertion site. After the first withdrawal from the vial, any solution remaining must be discarded because Irfen 600mg Lysine contains no preservative.
Since Irfen 600mg Lysine is potentially irritating to tissues, it should be administered carefully to avoid extravasation.
Irfen 600mg Lysine should not be simultaneously administered in the same intravenous line with Total
Parenteral Nutrition (TPN). If necessary, TPN should be interrupted for a 15-minute period prior to and after drug administration. Line patency should be maintained by using dextrose or saline.

What other drugs will affect Irfen 600mg?
Coumarin-Type Anticoagulants: Several short-term controlled studies failed to wshow that Irfen 600mg significantly affected prothrombin times or a variety of other clotting factors when administered to individuals on coumarin-type anticoagulants. However, because bleeding has been reported when Irfen 600mg and other nonsteroidal anti-inflammatory agents have been administered to patients on coumarin-type anticoagulants, the physician should be cautious when administering Irfen 600mg to patients on anticoagulants.
Aspirin: Animal studies wshow that aspirin given with nonsteroidal anti-inflammatory agents, including Irfen 600mg, yields a net decrease in anti-inflammatory activity with lowered blood levels of the non-aspirin drug. Single dose bioavailability studies in normal volunteers have failed to wshow an effect of aspirin on Irfen 600mg blood levels. Correlative clinical studies have not been performed.
Methotrexate: Apo-Irfen 600mg, as well as other nonsteroidal anti-inflammatory drugs, probably reduces the tubular secretion of methotrexate based on in vitro studies in rabbit kidney slices. This may indicate that Irfen 600mg could enhance the toxicity of methotrexate. Caution should be used if Irfen 600mg is administered concomitantly with methotrexate.
H-2 Antagonists: In studies with human volunteers, co-administration of cimetidine or ranitidine with Irfen 600mg had no substantive effect on Irfen 600mg serum concentrations.
Furosemide: Clinical studies, as well as random observations, have shown that Irfen 600mg can reduce the natriuretic effect of furosemide and thiazides in some patients. This response has been attributed to inhibition of renal prostaglandin synthesis. During concomitant therapy with Irfen 600mg, the patient should be observed closely for signs of renal failure, as well as to assure diuretic efficacy.
Lithium: Apo-Irfen 600mg produced an elevation of plasma lithium levels and a reduction in renal lithium clearance in a study of eleven normal volunteers. The mean minimum lithium concentration increased 15% and the renal clearance of lithium was decreased by 19% during this period of concomitant drug administration.
This effect has been attributed to inhibition of renal prostaglandin synthesis by Irfen 600mg. Thus, when Irfen 600mg and lithium are administered concurrently, subjects should be observed carefully for signs of lithium toxicity. (Read circulars for lithium preparation before use of such concurrent therapy).

What are the possible side effects of Irfen 600mg?
6.1 Clinical Trials Experience
The most frequently reported adverse events with Irfen 600mg Lysine were as shown in Table 1.
6.2 Renal Function
Compared to placebo, there was a small decrease in urinary output in the Irfen 600mg group on days 2-6 of life, with a compensatory increase in urine output on day 9. In other studies, adverse events classified as renal insufficiency including oliguria, elevated BUN, elevated creatinine, or renal failure were reported in Irfen 600mg treated infants.
6.3 Additional Adverse Events
The adverse events reported in the multicenter study and of unknown association include tachycardia, cardiac failure, abdominal distension, gastroesophageal reflux, gastritis, ileus, inguinal hernia, injection site reactions, cholestasis, various infections, feeding problems, convulsions, jaundice, hypotension, and various laboratory abnormalities including neutropenia, thrombocytopenia, and hyperglycemia.
6.4 Post-marketing Experience
The following adverse reactions have been identified from spontaneous post-marketing reports or published literature: gastrointestinal perforation, necrotizing enterocolitis, and pulmonary hypertension. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency, or establish a causal relationship to drug exposure.
