Hello,
Thank you for your query at DoctorSpring.com
I understand your concern.
Considering your body weight, 875 mg 12 hourly is fine. Higher dose than that can cause gastric irritation and upset.
Some doctors prefer higher dose, it is not wrong, but then it is not required.
I can assure you from my side 875 mg 12 hourly is fine.
Please feel free to discuss further,
Regards.
