Indications: Used for pain management in conditions such as muscle pain, joint pain, menstrual cramps, toothaches, headaches, fever, and post-surgery related pain.
Active Ingredients: The primary compositions found in search results include Tapentadol Hydrochloride 225 mg or a combination of Tapentadol 100mg + Carisoprodol 125mg, or Tramadol Hydrochloride 225 mg. Tapentadol and Tramadol act in the central nervous system to ease pain, while Carisoprodol functions as a muscle relaxer.
