A large randomized-controlled trial showing efficacy of diazepam in reducing hypertonia, increasing range of motion, passive and spontaneous movement in children with CP with relatively low incidence of adverse events. A small, double-blinded, randomized control trial of dantrolene versus placebo demonstrating the effectiveness in reducing muscle contraction, however, without obvious contribution to overall wellbeing or functional status. While OTC and natural alternatives are helpful and can be used with more potent muscle relaxants, it is essential to seek medical advice before starting or combining them. Although this is not exhaustive of the list of options, these serve as excellent muscle relaxants in the face of mild muscle tension and spasms.

  • While evidence exists to support its use, patient selection is unclear.
  • Cyclobenzaprine, or Flexeril, is a centrally acting muscle relaxant.

The specific use of these medications may vary depending on the individual patient, their medical condition, and the healthcare professional’s assessment.

Nonetheless, inconsistency of treatment has the potential to tremendously reduce the efficacy of dantrolene, both as a muscle relaxant and pain reliever from spasticity. A reasonable concern are adolescent patients who are independent but may not fully comprehend the long-term ramifications of nonadherence. Therefore, they may be less likely to adhere to a particular pharmacologic regimen.

However, like other muscle relaxers, it can be abused by some people. Abuse and dependence may occur with long-term use https://flexeril.live and lead to addictive habits. Both Zanaflex and Flexeril can interact with drugs that have CNS depressant effects.

Can I use Zanaflex or Flexeril while pregnant?

The symptoms can range from mild discomfort to intense, severe pain.

Tizanidine (Oral Route)

Other guidelines suggest that muscle relaxants cause increased drowsiness and should only be used short-term. Cyclobenzaprine, or Flexeril, is a centrally acting muscle relaxant. It functions over a prolonged time period via first order kinetics, with a half-life of up to 18 hours, and is ultimately excreted via the kidney. Tizanidine, also known by its brand name Zanaflex, is a short-acting muscle relaxant that was prescribed to approximately 3.5 million people in the US in 2020.
