PEMAZYRE dosing and administration — 4 of 5
Dose modifications for PEMAZYRE (1/2)
Dose modifications may be needed in cases of hyperphosphataemia and serous retinal detachment1
>5.5 – ≤7 mg/dL
>7 – ≤10 mg/dL
>10 mg/dL
Withhold
PEMAZYRE if levels do not return to <7 mg/dL within 2 weeks of starting a phosphate-lowering therapy
Restart
PEMAZYRE and phosphate-lowering therapy at the same dose when level returns to <7 mg/dL
Upon recurrence of serum phosphate at >7 mg/dL with phosphate-lowering therapy, reduce PEMAZYRE 1 dose level
Withhold
PEMAZYRE if levels continue >10 mg/dL for 1 week
Restart
PEMAZYRE and phosphate-lowering therapy 1 dose level lower when serum phosphate is <7 mg/dL
If there is a recurrence of serum phosphate >10 mg/dL following 2 dose reductions, permanently discontinue
