The exact mechanism of action of Prosoma 350mg is unknown. The medicine, however, may interfere with messages sent between the brain and the spinal cord. Carisoprodol works by blocking nerves from transmitting pain signals to the brain, hence reducing the sensation of pain. This helps reduce the discomfort and muscle spasms that might result from sickness or injury. People who are experiencing extreme pain and suffering may benefit from the sedative effects of Prosoma 350 mg pills. Prosoma should only be taken as directed by your doctor, who may recommend a lower starting dose and/or limit how long you should take the drug.
