  • 40-50 kg : 1250 mg

  • 51-60 kg: 1500 mg

  • 61-70 kg: 1750 mg

  • 71-80 kg: 2000 mg

  • 81-90 kg: 2250 mg

  • 91 kg or more: 2500 mg

Age 20-59

Q12H based on Actual body weight:

40-50 kg = 750 mg
51-70 kg = 1000 mg
71-90 kg = 1250 mg
91 kg or more: 1500 mg

Age 60-69

Q12-18H based on Actual body weight:

40-50 kg = 750 mg
51-70 kg = 1000 mg
71-90 kg = 1250 mg
