Norflex

Norflex (orphenadrine) is a muscle relaxant used to treat muscle spasms and to relieve pain from these spasms. It is often used in combination with rest, physical therapy, and other treatments. Norflex is available in both immediate-release and extended-release forms.

Pharmacology

Orphenadrine, the active ingredient in Norflex, is a muscarinic antagonist, which means it works by blocking the action of a neurotransmitter called acetylcholine in the central nervous system. This helps to relax muscles and reduce muscle spasms.

Uses

Norflex is used to relieve pain and discomfort caused by strains, sprains, and other muscle injuries. It is also used to treat other conditions as determined by a doctor.

Side Effects

Common side effects of Norflex include dry mouth, dizziness, drowsiness, upset stomach, constipation, and blurred vision. Serious side effects can include fast or irregular heartbeat, mental/mood changes, difficulty urinating, and decreased sexual ability.

Interactions

Norflex can interact with other medications, including certain antidepressants, antihistamines, and anticholinergics. It can also interact with alcohol and increase the risk of side effects.

Precautions

Before taking Norflex, patients should inform their doctor if they have any allergies, or if they have a history of glaucoma, heart disease, liver disease, or urinary problems.
