Tolmetin

INDICATIONS & USAGE Carefully consider the potential benefits and risks of TOLECTIN tablets, USP and other treatment options before deciding to use TOLECTIN tablets. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals (see WARNINGS ). TOLECTIN tablets are indicated for the relief of signs and symptoms of rheumatoid arthritis and osteoarthritis. TOLECTIN tablets are indicated in the treatment of acute flares and the long-term management of the chronic disease. TOLECTIN tablets are also indicated for treatment of juvenile rheumatoid arthritis. The safety and effectiveness of TOLECTIN tablets have not been established in pediatric patients under 2 years of age (see PRECAUTIONS : Pediatric Use and DOSAGE AND ADMINISTRATION ).

DOSAGE & ADMINISTRATION Carefully consider the potential benefits and risks of TOLECTIN and other treatment options before deciding to use TOLECTIN. Use the lowest effective dose for the shortest duration consistent with individual patient treatment goals (see WARNINGS ). After observing the response to initial therapy with TOLECTIN, the dose and frequency should be adjusted to suit an individual patient’s needs. For the relief of rheumatoid arthritis or osteoarthritis, the recommended starting dose for adults is 400 mg three times daily (1200 mg daily), preferably including a dose on arising and a dose at bedtime. To achieve optimal therapeutic effect the dose should be adjusted according to the patient’s response after 1 or 2 weeks. Control is usually achieved at doses of 600 mg to 1800 mg daily in divided doses (generally t.i.d.). Doses larger than 1800 mg/day have not been studied and are not recommended. For the relief of juvenile rheumatoid arthritis, the recommended starting dose for pediatric patients (2 years and older) is 20 mg/kg/day in divided doses (t.i.d. or q.i.d.). When control has been achieved, the usual dose ranges from 15 to 30 mg/kg/day. Doses higher than 30 mg/kg/day have not been studied, and, therefore, are not recommended. A therapeutic response to TOLECTIN can be expected in a few days to a week. Progressive improvement can be anticipated during succeeding weeks of therapy. If gastrointestinal symptoms occur, TOLECTIN can be administered with antacids other than sodium bicarbonate. TOLECTIN bioavailability and pharmacokinetics are not significantly affected by acute or chronic administration of magnesium and aluminum hydroxides; however, bioavailability is affected by food or milk (see PRECAUTIONS: Drug-Food Interaction ).

ADVERSE REACTIONS The adverse reactions which have been observed in clinical trials encompass observations in about 4,370 patients treated with TOLECTIN, over 800 of whom have undergone at least one year of therapy. These adverse reactions, reported below by body system, are among those typical of nonsteroidal anti-inflammatory drugs and, as expected, gastrointestinal complaints were most frequent. In clinical trials with tolmetin, about 10% of patients dropped out because of adverse reactions, mostly gastrointestinal in nature. Incidence Greater Than 1%: The following adverse reactions which occurred more frequently than 1 in 100 were reported in controlled clinical trials: Gastrointestinal: nausea (11%), dyspepsia*, gastrointestinal distress*, abdominal pain*, diarrhea*, flatulence*, vomiting*, constipation, gastritis, and peptic ulcer. Forty percent of the ulcer patients had a prior history of peptic ulcer disease and/or were receiving concomitant anti-inflammatory drugs including corticosteroids, which are known to produce peptic ulceration. Body as a Whole: headache*, asthenia*, chest pain Cardiovascular: elevated blood pressure*, edema* Central Nervous System: dizziness*, drowsiness, depression Metabolic/Nutritional: weight gain*, weight loss* Dermatologic: skin irritation Special Senses: tinnitus, visual disturbance Hematologic: Small and transient decreases in hemoglobin and hematocrit not associated with gastrointestinal bleeding have occurred. These are similar to changes reported with other nonsteroidal anti-inflammatory drugs. Urogenital: elevated BUN, urinary tract infection *Reactions occurring in 3% to 9% of patients treated with TOLECTIN. Reactions occurring in fewer than 3% of the patients are unmarked. Incidence Less Than 1%: (Causal Relationship Probable) The following adverse reactions were reported less frequently than 1 in 100 in controlled clinical trials or were reported since marketing. The probability exists that there is a causal relationship between TOLECTIN and these adverse reactions. Gastrointestinal: gastrointestinal bleeding with or without evidence of peptic ulcer, perforation, glossitis, stomatitis, hepatitis, liver function abnormalities Body as a Whole: anaphylactoid reactions, fever, lymphadenopathy, serum sickness Hematologic: hemolytic anemia, thrombocytopenia, granulocytopenia, agranulocytosis Cardiovascular: congestive heart failure in patients with marginal cardiac function Dermatologic: urticaria, purpura, erythema multiforme, toxic epidermal necrolysis Urogenital: hematuria, proteinuria, dysuria, renal failure Incidence Less Than 1%: (Causal Relationship Unknown) Other adverse reactions were reported less frequently than 1 in 100 in controlled clinical trials or were reported since marketing, but a causal relationship between tolmetin and the reaction could not be determined. These rarely reported reactions are being listed as alerting information for the physician since the possibility of a causal relationship cannot be excluded. Body as a Whole: epistaxis Special Senses: optic neuropathy, retinal and macular changes To report SUSPECTED ADVERSE REACTIONS, contact Poly Pharmaceuticals, Inc. at 1-256-270-7552 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch.

DRUG INTERACTIONS ACE Inhibitors: Reports suggest that NSAIDs may diminish the antihypertensive effect of ACE Inhibitors. This interaction should be given consideration in patients taking NSAIDs concomitantly with ACE Inhibitors. Aspirin: As with other NSAIDs, concomitant administration of TOLECTIN sodium and aspirin is not generally recommended because of the potential of increased adverse effects. Diuretics: Clinical studies, as well as post-marketing observations have shown that NSAIDs 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 NSAIDs, the patient should be observed closely for signs of renal failure, as well as to assure diuretic efficacy. Lithium: NSAIDs have produced an elevation of plasma lithium levels and a reduction in renal lithium clearance. The mean minimum lithium concentration increased 15% and the renal clearance was decreased by approximately 20%. These effects have been attributed to inhibition of renal prostaglandin synthesis by the NSAID. Thus, when NSAIDs and lithium are administered concurrently, subjects should be observed carefully for signs of lithium toxicity. Methotrexate: NSAIDs have been reported to competitively inhibit methotrexate accumulation in rabbit kidney slices. This may indicate that they could enhance the toxicity of methotrexate. Caution should be used when NSAIDs are administered concomitantly with methotrexate. Warfarin: The effects of warfarin and NSAIDs on GI bleeding are synergistic, such that users of both drugs together have a risk of serious GI bleeding higher than users of either drug alone. The in vitro binding of warfarin to human plasma proteins is unaffected by TOLECTIN, and TOLECTIN does not alter the prothrombin time of normal volunteers. However, increased prothrombin time and bleeding have been reported in patients on concomitant tolmetin and warfarin therapy. Therefore, caution should be exercised when administering tolmetin to patients on anticoagulants. Hypoglycemic Agents: In adult diabetic patients under treatment with either sulfonylureas or insulin there is no change in the clinical effects of either TOLECTIN or the hypoglycemic agents.
