    Uses

    Anaphylaxis acute - emergency treatment

    Dosage

    Adrenaline injection for self-administration should only be used for patients clearly identified at risk of an anaphylactic reaction and should always be carried by such patients in situations of special risk. Patients or their carers must be thoroughly instructed how to use adrenaline injection for self administration and the circumstances in which it should be used. Patients should be advised to seek immediate medical attention following the self-administration of adrenaline.

    Adults

    300micrograms, administered intramuscularly, as soon as signs and symptoms of anaphylaxis develop.
    Repeated after 5 to 15 minutes.

    In patients weighing 60kg or more, 500micrograms may be required.

    Children

    EpiPen
    Dosage may be 150micrograms or 300micrograms, depending on the body weight of the patient (10micrograms/kg body weight).

    Pregnancy and Lactation

    Pregnancy

    Use adrenaline with caution during pregnancy.

    The manufacturer notes that this medication should only be considered if the expected benefit to the mother is greater than any risk to the foetus.

    Adrenaline is teratogenic in some animal species, however human teratogenicity has not been studied.

    Adrenaline crosses the placenta and may dramatically reduce placental blood flow; although anaphylactic shock will also reduce placental blood flow. There is an increased risk of adverse reactions in pregnant patients. Schaefer (2007) comments that the systemic use of adrenaline is restricted to emergency use.

    Lactation

    Adrenaline is considered safe for use during breastfeeding.

    The manufacturer notes that adrenaline is not orally bioavailable.

    The product also has a short half life and is readily destroyed in the gastrointestinal tract. Any adrenaline excreted in breast milk would not be expected to have any effect on the nursing infant. Hale (2010) suggests the breastfeed infant is observed for brief stimulation.

    Counselling

    Advise patients to check the product to ensure it is replaced within the expiry period and also to visually inspect the product to make sure the solution is clear and colourless.
    Do NOT inject into the extremities or penis Avoid administration in the gluteal region Advise patient not to drive or operate machinery until assessed Patient and prescriber should be aware of risk minimisation material When given by carer, immobilise patient's leg to reduce risk of laceration
