Norflex is an oral tablet made up of a skeletal muscle relaxant called orphenadrine. This medication is available in both the brand choice and generic alternative in 100mg!

Norflex is prescribed to treat muscle spasms or pain. Norflex is most commonly used along with rest, physical therapy and other treatments. Muscle spasms/pain is not associated with cancer or any harmful diseases and is usually short lived; however, they can occur abruptly, causing not only pain but also a decrease in productivity and confidence. When muscle spasms occur, it is due to the nervous system in the brain sending signals to the muscles to order them to tighten or contract.

Norflex is effective in treating muscle spasms because it is able to reduce the strength of the signal sent from the nervous system to the muscles that causes muscle spasms to occur.

Instructions given by your doctor can be found on the prescription bottle; ensure you are following only the directions given by your doctor.

Norflex is commonly taken twice a day, once during the morning hours and once in the evening. Avoid crushing or chewing this medication; swallow it whole.

The Norflex medication is only part of the treatment; ensure you are following the entire treatment plan including rest, physical therapy, or other pain relief measures.

Store this medication at room temperature, protected from heat, light, and moisture. Keep the bottle tightly closed. Keep track of how much medicine is in the bottle after using it; Norflex can be a drug of abuse and you should be aware if any medicine goes missing.
