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. The drug is contraindicated in patients who have demonstrated a previous hypersensitivity to the drug.

Confusion, anxiety and tremors have been reported in a few patients receiving propoxyphene and orphenadrine concomitantly. As these symptoms may be simply due to an additive effect, reduction of dosage and/or discontinuation of one or both agents is recommended in such cases. Safety of continuous long term therapy with Norgesic TM Tablets has not been established; therefore, if Norgesic TM Tablets are prescribed for prolonged use, periodic monitoring of blood, urine and liver function values is recommended. Pregnancy Embryo-Fetal Toxicity Inform pregnant women to avoid use of aspirin and other NSAIDs starting at 30 weeks gestation because of the risk of the premature closing of the fetal ductus arteriosus. If treatment with Norgesic TM Tablets is needed for a pregnant woman between about 20 to 30 weeks gestation, advise her that she may need to be monitored for oligohydramnios, if treatment continues for longer than 48 hours [ see WARNINGS; Fetal Toxicity, PRECAUTIONS; Pregnancy ] . Serious Skin Reactions, including DRESS Advise patients to stop taking Norgesic TM Tablets immediately if they develop any type of rash or fever and to contact their healthcare provider as soon as possible [ see Warnings ].

Orphenadrine citrate is a centrally acting (brain stem) compound which in animals selectively blocks facilitatory functions of the reticular formation. Orphenadrine does not produce myoneural block, nor does it affect crossed extensor reflexes. Orphenadrine prevents nicotine-induced convulsions but not those produced by strychnine. Chronic administration of orphenadrine citrate, aspirin and caffeine to dogs and rats has revealed no drug-related toxicity. No blood or urine changes were observed, nor were there any macroscopic or microscopic pathological changes detected. Extensive experience with combinations containing aspirin and caffeine has established them as safe agents. The addition of orphenadrine citrate does not alter the toxicity of aspirin and caffeine. The mode of therapeutic action of orphenadrine has not been clearly identified, but may be relegated to its analgesic properties. Orphenadrine citrate also possesses anti-cholinergic actions.
