About Orphenadrine Citrate ER

What is this medication? Orphenadrine citrate ER is a skeletal muscle relaxant primarily used to treat discomfort associated with acute, painful musculoskeletal conditions. It is specifically designed to help relieve muscle spasms and tension caused by injuries such as strains or sprains. Rather than acting directly on the skeletal muscles, this medication works by affecting the central nervous system to help reduce pain sensations and promote relaxation.

This medication is generally prescribed as part of a broader recovery plan that includes rest and physical therapy to improve mobility and healing. Because it is an extended-release formulation, the drug is gradually released into the bloodstream over several hours, providing prolonged relief throughout the day or night. It is intended for short-term use to manage the initial stages of muscle pain and should be used exactly as directed by a healthcare provider.

Prescribing information

From the FDA-approved label for Orphenadrine Citrate ER. Official source: DailyMed (NLM) · Label effective Dec 31, 2024

Indications and usage
3. Indications and Usage Section INDICATIONS AND USAGE Orphenadrine citrate extended-release tablets are indicated as an adjunct to rest, physical therapy, and other measures for the relief of discomfort associated with acute painful musculoskeletal conditions.
Dosage and administration
10. Dosage and Administration Section DOSAGE AND ADMINISTRATION Adults Two tablets per day; one in the morning and one in the evening.
Contraindications
4. Contraindications Orphenadrine citrate extended-release tablets are contraindicated in patients with glaucoma, pyloric or duodenal obstruction, stenosing peptic ulcers, prostatic hypertrophy or obstruction of the bladder neck, cardio-spasm (mega-esophagus) and myasthenia gravis. Orphenadrine citrate tablets are contraindicated in patients who have demonstrated a previous hypersensitivity to the drug.
Warnings
5. Warnings Some patients may experience transient episodes of light-headedness, dizziness or syncope. Orphenadrine 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.
Adverse reactions
7. Adverse Reactions Adverse reactions of orphenadrine are mainly due to the mild anticholinergic action of orphenadrine, and are usually associated with higher dosage. Dryness of the mouth is usually the first adverse effect to appear. When the daily dose is increased, possible adverse effects include: tachycardia, palpitation, urinary hesitancy or retention, blurred vision, dilatation of pupils, increased ocular tension, weakness, nausea, vomiting, headache, dizziness, constipation, drowsiness, hypersensitivity reactions, pruritus, hallucinations, agitation, tremor, gastric irritation, and rarely urticaria and other dermatoses. Infrequently, an elderly patient may experience some degree of mental confusion. These adverse reactions can usually be eliminated by reduction in dosage. Very rare cases of aplastic anemia associated with the use of orphenadrine tablets have been reported. No causal relationship has been established.
