Carisoprodol – A Detailed Guide
Carisoprodol is an effective medication used for musculoskeletal pain. It is available under various brand names. The standard dosage of this medication is 350 mg.

If you’ve ever suffered from muscle pain due to muscle spasms, sprains, or strains, you know how difficult it can be to do your daily activities. Most of us try different home remedies to feel better, like resting and taking over-the-counter medications.
If that fails and the pain is not resolved with home remedies, then muscle relaxers like carisoprodol are what your physician recommends.

Carisoprodol: Mechanism Of Action (How Does Carisoprodol Work?)
Carisoprodol works by altering or blocking communication between the nerves and the brain. Thus, the nerve cannot send pain signals to the brain, and as a result, we don’t feel the pain sensation [2].
Carisoprodol is metabolized in the liver and excreted through the kidneys via urination.
In the liver, Carisoprodol is metabolized to meprobamate, which contributes to the abuse potential of the muscle relaxer.
Carisoprodol Dosage
Carisoprodol is available in dosage strengths of 250, 350, and 500. However, the standard dosage of this muscle relaxer is 350 mg, which should be taken three times a day and during bedtime.
Whereas Soma 500 mg is recommended for patients when the lower dosages of the medication do not provide effective pain relief.
