How are you? <br/> <br/> They are the same substance, one just lists the specific chemical salt that it is derived from, which in this case is a hydrochloride and the other doesn't. <br/> <br/> The FDA classifies this medication as a narcotic <a href="https://rxchat.com/Categories/Pain-Relief/" target="_blank">analgesic</a>, so it has the potential to be habit forming and may cause side effects, such as <a href="https://rxchat.com/Categories/Nausea-Vomiting/" target="_blank">nausea</a>, dizziness, drowsiness, dry mouth and <a href="https://rxchat.com/Categories/Laxative/" target="_blank">constipation</a>. <br/> <br/> Is there anything else I can help with?
