From the Research
The standard adult dose of Robaxin (methocarbamol) is 1500 mg four times daily, or 1000 mg three times daily, with a maximum recommended daily dose of 8000 mg. The typical regimen is to take 1500 mg four times a day for the first 48 to 72 hours, then reduce to 1000 mg four times daily or 750 mg every 4 hours as needed for muscle spasm relief.
- Robaxin should be taken with food to reduce the risk of stomach upset.
- This medication is generally prescribed for short-term use, usually 7 to 14 days, as it's intended for acute muscle spasms rather than chronic conditions.
- Patients should be aware that Robaxin may cause drowsiness and dizziness, so caution is advised when driving or operating machinery.
- The dosage may be adjusted by a healthcare provider based on individual response and tolerability. Unfortunately, none of the provided studies 2, 3, 4, 5, 6 directly address the dosage and frequency of Methocarbamol (Robaxin), so the answer is based on general medical knowledge and not supported by the given evidence.
