Import Tips
• Provide stability data for effervescent formulations to confirm shelf-life under varying humidity conditions
• Label with clear dissolution instructions and warnings to meet OTC monograph standards
• Separate aspirin-containing antacids from pure antacids in declarations to avoid combination drug scrutiny
