Promptly address any violations described herein without delay, including ensuring that appropriate resources are allocated to fully address them and prevent their recurrence. This is not intended to be an all-inclusive list of the violations that may exist in connection with your products or operations. It is your responsibility to ensure that your firm complies with all requirements of federal law, including FDA regulations.

FDA confirmed through laboratory analysis that your product labeled as “Sâm Xương Khớp Ông Tiên” contains piroxicam and dexamethasone phosphate. Piroxicam is a type of pain and inflammation reliever known as an NSAID. NSAIDs can increase the risk of serious heart problems, such as heart attack and stroke, and can cause serious gastrointestinal problems, such as bleeding, ulcers or life-threatening tears in the stomach or intestinal lining. Piroxicam can interact with other medications, especially other NSAID-containing products, and may significantly increase the risk of these serious side effects. Dexamethasone is a steroid medication commonly used to reduce inflammation. However, it can weaken the immune system, making it harder for the body to fight infections.
