Indications
Robaxisal Extra Strength is a medication used to treat back pain, muscle spasms, tense neck muscles, strains, and sprains. It has a dual-acting formula that contains an analgesic (acetylsalicylic acid) to relieve pain and a muscle relaxant (methocarbamol) to get to the source of pain. It contains two active ingredients: 500 mg of acetylsalicylic acid (ASA) to relieve pain and 400 mg of methocarbamol to relax tense back muscles.
Methocarbamol is a muscle relaxant that is used to treat muscle spasms and pain, while aspirin is a nonsteroidal anti-inflammatory drug (NSAID) that helps to decrease pain and inflammation. Together, these two drugs work to relieve pain and muscle spasms.
