Drug Description


Robaxacet Extra Strength is an oral medication commonly prescribed for conditions such as back pain, tense neck muscles, strains, and sprains. It can be used for the relief of pain associated with muscle spasm or tension. 

Robaxacet contains an analgesic called acetaminophen (also known as paracetamol) and a muscle relaxant called methocarbamol. The acetaminophen helps to relieve pain, while the methocarbamol helps to relax tense muscles. The combination helps to alleviate pain and relax tense muscles
