    Precautions and Warnings

    Children aged 12 to 18 years

    Before starting therapy ensure immunisations are up to date
    Treatment to be initiated and supervised by a specialist
    Contains sorbitol
    Potential for polyethylene glycol accumulation: Monitor renal function
    If dose is increased, monitor LDH at least every 4 weeks
    Monitor lactate dehydrogenase (LDH) regularly
    Monitor patient closely for haemolysis
    Monitor patient for signs of serious infection
    Advise patient to report symptoms of infection immediately
    May interfere with certain laboratory measurements
    Interrupt treatment if severe infusion reaction occurs
    Female: Contraception required during and for 2 months after treatment
    Give patient package leaflet and patient reminder card

    All patients must be vaccinated against encapsulated bacteria including Neisseria meningitidis, Streptococcus pneumoniae and Haemophilus influenzae following vaccination guidelines at least 2 weeks prior to treatment. Patients with a history of vaccinations against Streptococcus pneumoniae, Neisseria meningitidis types A, C, W, Y and B and Haemophilus influenzae type B should ensure that it occurred within the last 2 years.

    Patients without a history of vaccinations will need the required vaccinations to be administered at least 2 weeks prior to receiving the first dose of treatment. If immediate therapy is required, administer the required vaccinations and treat the patient with suitable antibiotics until 2 weeks after vaccination.

    If treatment is discontinued, monitor patients for at least 8 weeks for signs and symptoms of serious intravascular haemolysis and other reactions. Serious intravascular haemolysis is identified by elevated LDH levels with sudden decrease in PNH close size or haemoglobin, or reappearance of symptoms such as fatigue, haemoglobinuria, abdominal pain, dyspnoea, major adverse vascular even (including thrombosis), dysphagia or erectile dysfunction. Consider the following treatments for serious haemolysis: blood transfusions (packed RBCs), exchange transfusions, anticoagulation, and corticosteroids.

    Avoid administration into areas with tattoos, scars, stretch marks. Skin that is tender, bruised, red or hard should also be avoided.

    Pregnancy and Lactation


    Pegcetacoplan is contraindicated during pregnancy.

    The manufacturer advises that pegcetacoplan is not recommended during pregnancy. There are limited data for use of pegcetacoplan during pregnancy and animal studies have indicated reproductive toxicity.


    Pegcetacoplan is contraindicated during breastfeeding.

    The manufacturer advises that pegcetacoplan should be discontinued during breastfeeding. It is unknown whether pegcetacoplan is excreted in human milk, however it has been noted that it is unlikely a breastfed infant will have clinically relevant exposure. Animal studies have indicated a low excretion level.
