Headache

Call 000 for a sudden, severe headache, or headache with confusion, a stiff neck, vomiting or new vision changes. A familiar mild headache may improve with rest and water.

Medical emergency? Call 000

What to do

  1. Check warning signs

    Check for emergency symptoms before treating the pain as a routine headache.

    Take care. Do not assume a new or different headache is your usual migraine.

    Take care. Do not drive yourself if confused, faint or visually affected.

  2. Mild, familiar headache: rest

    For a mild, familiar headache without warning signs, rest in a quiet room and drink water.

  3. Ask about suitable pain relief

    Ask a pharmacist about suitable pain relief. Follow the label and any existing treatment plan.

Know when to act
