Finding a dose to meet your treatment goals
During your PALYNZIQ treatment, your healthcare provider will adjust your injection schedule to find a dose that’s right for you. You will start injecting PALYNZIQ once a week, and your healthcare provider will then increase the number of injections per week based on how the therapy works for you.
This treatment plan is only an example. Always follow your healthcare provider’s instructions.
Additional time may be required between dose escalations based on patient tolerability.
Individualize treatment to the lowest effective and tolerated dosage. Consider increasing to a maximum of 40 mg subcutaneously once daily in patients who have not achieved a response after at least 24 weeks of continuous treatment with 20 mg subcutaneously once daily.
Discontinue PALYNZIQ if either a ≥20% reduction from baseline or a blood Phe concentration ≤600 micromol/L (10 mg/dL) is not achieved after at least 16 weeks of continuous treatment with 40 mg subcutaneously once daily.
