Your healthcare provider will consider your medical history, current medications, and other factors when recommending a dosage of Robaxin. For the tablet form, the recommended starting dose is 1500 mg, four times daily, for the first two or three days of treatment. After that, the amount may be reduced. Higher dosages are often needed when Robaxin is used for tetanus treatment.
The dose of Robaxin® (methocarbamol) your healthcare provider recommends will vary, depending on a number of factors, including:
- How you respond to this medication
- The severity of your condition
- Other medications you take
- Any other medical conditions you may have.
As is always the case, do not adjust your dosage unless your healthcare provider specifically tells you to do so.
Robaxin tablets come in two different strengths: 500 mg (generic only) and 750 mg. The recommended starting dose of Robaxin is 1500 mg (three 500-mg tablets or two 750-mg tablets) four times daily for the first two to three days of treatment. Then, the dosage should be reduced to 1500 mg twice daily, 1000 mg four times daily, or 750 mg six times daily.
Recommended Dosing for Robaxin Injection
For most purposes, a single 1-g (1000 mg) dose of Robaxin injection given into a muscle (intramuscularly) or into a vein (intravenously) is sufficient, after which the person may be switched to Robaxin tablets. If absolutely necessary, the dosage may be repeated every eight hours for a maximum of three days.
If continued use is necessary, the three-day course of Robaxin may be repeated, but only after stopping the drug for at least 48 hours.
For tetanus treatment, much higher doses may be necessary, and you may need to take the medication for a longer period.
