Thiazide overdose: 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

    In other countries, contact the local poison information centre or emergency medical service.

    Call emergency services now if the person:

    • Collapses, faints, or cannot be awakened
    • Has trouble breathing
    • Has a seizure
    • Is severely confused
    • Has chest pain or a markedly irregular heartbeat
    • Has taken an intentional overdose
    • May have taken several medicines or an unknown substance

    Routine follow-up is different from emergency care.

    After treatment, contact the recommended clinician for repeat blood tests, medication review, or continuing dizziness.

    And for anyone, someone who:

    • is unconscious, or cannot be woken
    • you believe has taken an overdose or swallowed something poisonous
    Other emergency signs, for anyone
    • Someone who is struggling to breathe, gasping, choking, or cannot get words out
    • 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 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
  2. 2

    Is any of this happening?

    Be seen today

    Contact a poison centre immediately after a suspected thiazide overdose, even if there are no symptoms.

    In the United States, call Poison Control at 1-800-222-1222 or use its online service.

    New fainting, worsening confusion, very low urine output, or severe weakness needs urgent reassessment rather than waiting for a routine appointment.

  3. 3

    Does any of this apply?

    Book an appointment

    And for anyone, someone who:

    • is having side effects from a medicine, or is struggling to take it as prescribed

The article also says

Stay with the person while help is arranged.

If safe, keep the medicine container or packaging available.

Do not drive someone who is faint, severely drowsy, confused, or medically unstable.

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