Allergy shots: when to get help

Go through these in order and stop at the first one that applies. If you are reading this for someone else, answer for them.

  1. 1

    Is any of this happening now?

    Call 911

    Call emergency services immediately for trouble breathing, throat or tongue swelling, faintness, confusion, blue or grey lips, or symptoms involving several body areas.

    Do not wait to see whether symptoms settle, and do not drive yourself to emergency care.

    And for anyone, someone who:

    • is struggling to breathe, gasping, choking, or cannot get words out
    Other emergency signs, for anyone
    • Someone who has chest pain, tightness or pressure lasting more than a few minutes
    • Someone who has sudden weakness or drooping on one side of the face or body, slurred speech, or sudden confusion
    • Someone who is unconscious, or cannot be woken
    • Someone who is bleeding heavily and it will not stop with firm pressure
    • Someone who has had a seizure that will not stop, or does not wake up afterwards
    • Someone who has lips or skin that look pale, blue, grey or blotchy
    • Someone who you believe has taken an overdose or swallowed something poisonous
  2. 2

    Is any of this happening?

    Seek urgent medical advice for a rapidly worsening reaction, even if it initially seems mild.

    Use epinephrine immediately if it has been prescribed for you.

The article also says

Contact your allergy clinic before the next injection if you develop a large or long-lasting injection-site reaction, hives after leaving, new asthma symptoms, or another delayed reaction.

Also call if you become ill, start a new medicine, become pregnant, or miss scheduled doses.

Every sign above is quoted from the sofidex article on Allergy shots. If you are not sure, err upward — it is always reasonable to be checked.
