Product Description

Robaxin is a centrally acting muscle relaxant having trade name Methocarbamol. The drug’s mechanism of action is not known as yet but medical researchers assess that it inhibits carbonic anhydrase. The drug depresses the central nervous system and blocks the transmission of pain impulses to the brain, thereby aiding in relaxing the muscles.


Robaxin is used for soothing sprained muscles, strains, spasms, and other muscle injuries. The dosage depends on the level of pain, which may be moderate to severe. Since the drug has a short half-life, multiple doses a day may be prescribed and then reduced as the person recovers. The pill should not be considered as a stand-alone treatment but used along with rest and physical therapy to enable the recuperative process. If required, the drug may be used in treating other health problems for its therapeutic effects.


For soothing spasms and stiff muscles, the total dose of Robaxin in the beginning would be 1500 mg per day. Three 500 mg tablets can be taken in equal intervals.

One should also read the instructions on the product label to know about the product completely before taking Robaxin. The dosing instructions must be followed exactly as advised and should not be modified on one’s own. While consulting the doctor one should inform if he or she has myasthenia gravis as the drug can affect this illness.

Adequate rest and other pain relief techniques must be followed for the drug to be more effective and for the individual to recover.

Persons using Robaxin should avoid doing any work that requires complete focus or operate any hazardous machines, including driving.

Mild to moderate side effects of Robaxin include trouble sleeping, dizziness, headache, nausea, rash, stuffy nose, itching, flushing, drowsiness and blurred vision.

Under such circumstances, the person should consult with the healthcare provider immediately. Improper administration of the pills or abuse can also increase the risk of side effects. Any allergic reactions from the use of Methocarbamol must also be treated immediately.
