Flexeril is primarily prescribed for which condition?

Flexeril, known generically as cyclobenzaprine, is primarily prescribed to relieve muscle spasms. This medication is a centrally acting muscle relaxant that works by inhibiting the motor activity in the brainstem and spinal cord, resulting in a reduction of muscle tone and spasm. It is often used in conjunction with rest, physical therapy, and other treatments for managing acute musculoskeletal conditions.

In the context of the other potential conditions listed, Flexeril is not commonly used for seizures, infections, or general pain relief in the broader sense. Seizures are typically treated with anticonvulsants, infections require antibiotics or antivirals suited to the specific pathogen, and while Flexeril may alleviate discomfort associated with muscle spasms, it is not considered a primary treatment for pain relief in general, which could involve a wide array of medications depending on the underlying cause. Thus, the primary indication for Flexeril remains the treatment of muscle spasms.
