Orphenadrine Citrate, Aspirin And Caffeine

INDICATIONS & USAGE Norgesic TM (orphenadrine citrate, aspirin and caffeine 25 mg/ 385 mg/ 30 mg) Tablets are indicated in: Symptomatic relief of mild to moderate pain of acute musculoskeletal disorders. The orphenadrine component is indicated as an adjunct to rest, physical therapy, and other measures for the relief of discomfort associated with acute painful musculoskeletal conditions. The mode of action of orphenadrine has not been clearly identified, but may be related to its analgesic properties. Norgesic TM Tablets do not directly relax tense muscles in man.

ADVERSE REACTIONS Side effects of Norgesic TM Tablets are those seen with aspirin and caffeine or those usually associated with mild anti-cholinergic agents. These may include tachycardia, palpitation, urinary hesitancy or retention, dry mouth, blurred vision, dilation of the pupil, increased intraocular tension, weakness, nausea, vomiting, headache, dizziness, constipation, drowsiness, and rarely, urticaria and other dermatosis. Infrequently, an elderly patient may experience some degree of confusion. Mild central excitation and occasional hallucinations may be observed. These mild side effects can usually be eliminated by reduction in dosage. One case of aplastic anemia associated with the use of orphenadrine citrate, aspirin and caffeine has been reported.

WARNINGS Reye’s Syndrome may develop in individuals who have chicken pox, influenza, or flu symptoms. Some studies suggest possible association between the development of Reye’s Syndrome and the use of medicines containing salicylate or aspirin. Norgesic TM Tablets contain aspirin and therefore are not recommended for use in patients with chicken pox, influenza, or flu symptoms. Norgesic TM Tablets may impair the ability of the patient to engage in potentially hazardous activities such as operating machinery or driving a motor vehicle; ambulatory patients should therefore be cautioned accordingly. Aspirin should be used with extreme caution in the presence of peptic ulcers and coagulation abnormalities. CONTRAINDICATIONS Because of the mild anticholinergic effect of orphenadrine, Norgesic TM Tablets should not be used in patients with glaucoma, pyloric or duodenal obstruction, achalasia, prostatic hypertrophy or obstructions at the bladder neck. Norgesic TM Tablets are also contraindicated in patients with myasthenia gravis and in patients known to be sensitive to aspirin or caffeine.
