Chlorzoxazone 500 mg?

Chlorzoxazone is a prescription muscle relaxant used for short-term relief of acute musculoskeletal pain and spasms, usually in combination with rest and physical therapy.

If you’re taking a 500 mg tablet, typical dosing (as prescribed by a clinician) is usually:
- 500 mg every 6 hours as needed
- Do not exceed 2,000 mg (2 g) in a 24-hour period
- Some patients may start with 500 mg three times daily and adjust as directed by a doctor

Commonly used duration is short-term (often a few days to a couple of weeks), depending on your condition and doctor’s instructions.

Important safety and cautions:
- Do not use if you have a known allergy to chlorzoxazone or any tablet ingredients.
- Use with caution in liver problems; hepatotoxicity has been reported. Liver tests may be advised if therapy is prolonged or if you have liver disease.
- May cause drowsiness, dizziness, or lightheadedness. Avoid driving or operating machinery until you know how it affects you.
- Avoid or limit alcohol and other central nervous system depressants (sleep aids, benzodiazepines, opioids) while taking this medication.
- Tell your clinician about any other medications you’re taking (including over-the-counter meds and herbal supplements) to check for interactions.

Common side effects:
- Drowsiness, dizziness
- Upset stomach, nausea
- Rash (rare but serious; seek medical attention if you develop a rash, itching, or yellowing of the skin/eyes)

Serious but rare: signs of liver problems (yellowing eyes/skin, dark urine, persistent nausea/vomiting, unusual fatigue) or severe allergic reactions (rash with trouble breathing, swelling of face/t throat).

If you suspect an overdose (extremely drowsy, slowed breathing, fainting), seek emergency help.

If you’re comfortable, tell me:
- Are you taking this 500 mg dose as prescribed?
- Do you have liver disease or take other sedating medications?
- What symptoms or concerns prompted you to ask about chlorzoxazone 500 mg?

I can tailor safety and dosing info to your situation.
