How the Medication Works - Drug Action:

Carisoprodol works by blocking the communication between nerves in the brain and spinal cord that are responsible for awakeness and arousal. By blocking these CNS signals, signals that tell muscles to contract and tighten are also blocked.

Side Effects:

Many people take carisoprodol without side effects. However, that is no guarantee from potential side effects. The drug may cause:

  • drowsiness
  • agitation
  • nervousness
  • tremor
  • irritability
  • inability to sleep
  • depression
  • clumsiness
  • headache
  • fast heart beat
  • upset stomach
  • vomiting
  • skin rash

More Serious Side Effects:

The more serious side effects from taking carisoprodol require immediate medical attention:

  • difficulty breathing
  • fever
  • weakness
  • burning eyes


    Because carisoprodol suppresses the nerves that are responsible for awakeness and arousal, you may get drowsy or experience clumsiness. Exercise caution when deciding to drive or operate machinery. Taking carisoprodol with alcohol will amplify these effects.

    Before taking carisoprodol, tell your doctor if you have:

    • allergies
    • drug abuse or dependence
    • liver disease
    • kidney disease
    • prophyria
    • epilepsy, or any seizure disorder

    Precautions - Drug Interactions:

    It is always best to tell your doctor you medical history as well as any other medications (both over-the-counter and prescribed), as well as herbal supplements, vitamins and minerals. Specifically, tell him/her about:

    • anti-histamines
    • anti-depressants
    • sedatives
    • tranquilizers
    • sleep aids
    • pain medication
    • barbiturates
    • seizure medication
    Any medication that induces drowsiness will affect you if you also take carisoprodol. For more information on drug interactions with carisoprodol, use the Drug Finder.
