If you are in an emergency situation, you can view the Cortisol Sick Day Rules table (a quick reference guide to managing illness for those taking cortisol replacement) and the Adrenal Crisis Signs Table (a quick reference for signs of potential adrenal crisis). These tables may be helpful in identifying an adrenal crisis and in managing sick days dosing.

The information on these tables are also shown below in a mobile friendly format.

During normal health and life, when we become ill or suffer injuries our bodies produce increased levels of cortisol to help us survive those stresses.

If you are unable to produce your own cortisol, you need to be aware of when to provide an increased cortisol level using medication. This may happen during stressful times or ill health. The amount of increase needed, the way the cortisol is given, and the length of time the increase is needed will vary depending on the situation you are in.

The page below outlines

This may happen during stressful times or ill health. The amount of increase needed, the way the cortisol is given, and the length of time the increase is needed will vary depending on the situation you are in.

Cortisol Clock

The cortisol clock gives approximate times of need for emergency medical help and replacement.
Emergency cortisol replacement peak timings for clinical use
A = period of first feeling unwell (within, or up to, one hour)

B = period of increasing illness (failure to retain oral cortisol) (during 2nd hour)

C = DANGER ZONE – emergency cortisol injection needed and call 999 stating adrenal crisis(by the 3rd hour)

Below we outline the more common life events when an increase in cortisol cover would be needed and provides advice as to how long the increase should be for and in what form the cortisol should be given (tablets, injection to muscle or direct into vein).

Illness/situation

Adrenal crisis – weak, dizzy, nausea, faint, loss of consciousness

Give emergency injection if possible, and then dial 999 and state adrenal crisis.

This is urgent, and hospital admission is needed to stabilise.

Temperature higher than 38c, signs of infection or proven to have infection (urine tract, chest, tonsillitis etc)

Action to take: 2-3 times all normal doses of Hydrocortisone for duration of infection

Level of care needed: GP/Self care, if symptoms not resolved at 48 hours see GP may need antibiotic treatment

Antibiotic treatment for infections

Action to take: Double all normal doses for duration of antibiotics (usually 3-7 days)

Vomiting with/without diarrhoea

Action to take: Take extra dose immediately at onset of vomiting. Emergency 100mg injection if vomiting recurs within 30mins of taking extra dose .

Level of care needed: Urgent if unable to tolerate fluids and emergency injection used need admission to stabilise. GP if able to tolerate fluids and retain oral Hydrocortisone, check Sodium within range. May need anti-sickness treatment.

Diarrhoea (frequent watery stools)

Action to take: If no vomiting double all doses of Hydrocortisone until diarrhoea settles. If signs of adrenal crisis follow advice for that.

Level of care needed: Self care/GP. Urgent if signs of adrenal crisis.

Significant Accident/Falls/Injury

Action to take: If able double dose hydrocortisone as soon as incident happens. If significant injury eg broken bone, give emergency injection.

Level of care needed: Self care. Urgent if significant injury as need hydrocortisone cover and injury treated

Severe shock- bereavement, road traffic accident, witness to trauma

Action to take: Take 20mg as tablets if able or double usual dose of prednisolone if able. May need to use emergency injection if shock is severe.

Level of care needed: See GP or hospital for further advice. Sudden and severe shock may be classed as emergency – seek medical attention if in doubt.

Long haul flight over 12 hours

Action to take: Double usual dose on day of flight. One double dose should suffice.

General stress, exams, etc.

Action to take: Not usually required. Ask GP if concerned

Dental treatments

Extraction with anaesthetic

Action to take: 100mg intra muscular (via injection) just before extraction

Level of care: Double dose 24 hours then return to normal

Root canal – local anaesthetic

Action to take: Double dose 1 hr prior to surgery

Level of care: Double dose 24 hours then return to normal

Filling, dental hygiene

Action to take: Double dose 1 hr prior to procedure

Level of care: Double dose 24 hours then return to normal

Surgery

Surgery with long recovery – e.g. heart, bowel

Action to take: 100mg IV with anaesthetic, then 100mg IV every 6hrs or 200mg continuous IV over 24hrs until able to eat/drink. Then double normal dose for 48hrs, then taper back to normal.

Level of care needed: Tell the anaesthetist and surgeon that you take hydrocortisone before the operation. Replacement at time of surgery and immediately post operatively should be managed by surgical teams.

Surgery with quick recovery – e.g. joint replacement

Action to take: 100mg IV with anaesthetic, then 100mg IV every 6hrs or 200mg continuous IV over 24hrs until able to eat/drink. Then double normal dose for 48hrs, then taper back to normal.

Level of care needed: Tell the anaesthetist and surgeon that you take hydrocortisone before the operation. Replacement at time of surgery and immediately post operatively should be managed by surgical teams.

Minor surgery- cataract, hernia

Action to take: 100mg intra muscular (via injection) pre anaesthetic, double normal dose for 24 hrs post surgery, then normal doses.

Level of care needed: Tell the anaesthetist and surgeon that you take hydrocortisone before the operation. Replacement at time of surgery and immediately post operatively should be managed by surgical teams.

Minor surgery with local anaesthetic – mole removal

Action to take: Take extra dose 1 hour pre procedure, extra dose 1 hour post procedure, then normal doses.

Colonoscopy/Barium enema

Action to take: Double your usual dose as soon as the preparatory laxatives take effect and for duration
of the preparation.
For colonoscopy only: a 100mg injection 30 minutes before procedure to be given by doctor. Take usual dose on morning of procedure.

Some centres may want to admit you to hospital the night before to give the bowel prep and provide hydrocortisone cover.

Level of cover needed: Drink lots of water to prevent dehydration. Tell the doctor before procedure that you take hydrocortisone.

Gastroscopy

Action to take: 100mg intra muscular or intra venous at start of procedure.

Level of cover needed: Tell the doctor before procedure that you take hydrocortisone. Double dose for 24 hours.

Cystoscopy

Action to take: 100mg intra muscular immediately pre-procedure.

Level of cover needed: Double dose 24hr then resume as normal. Tell the doctor before procedure that you take hydrocortisone.

Adrenal Crisis

If you cannot absorb your tablets, or your usual replacement wasn’t sufficient for an acute shock or illness. This may happen gradually or perhaps quite quickly. You would feel weak, sickly and light headed. Below we outline the signs of adrenal crisis and the actions needed to take. If you find you have more than one of these symptoms at the same time, your Cortisol levels are likely to be dropping or too low. Equally, if you find symptoms start to accumulate, e.g. headache, followed by nausea, then feel shivery cold, with legs aches and fatigue, this may also indicate a likely reduction in cortisol levels. Taking extra Cortisol by mouth as instructed for Sick Day cover at this time can often prevent a full-blown adrenal crisis.

Our emergency information page gives more guidance on how to deliver an emergency hydrocortisone injection.

You should always seek medical advice if you have needed to use your emergency injection or if an increased dose of your tablets has not helped to resolve your symptoms.

Signs of infection:

  • Body temperature above 38c, skin hot to touch
  • Shivery/feeling cold/chills
  • Headache
  • Muscle and joint pains
  • Increased tiredness/fatigue
  • Swollen lymph nodes- neck armpit and groin
  • Nausea and possibly vomiting
  • You may notice increased respiratory rate, increase in pulse rate

Symptoms should stabilise with the increase in oral cortisol replacement; if this does not happen then seek medical attention via NHS111/A&E. If symptoms stabilise but do not resolve within 48-72hrs then seek GP review, especially if signs of infection as further treatments may be needed. If in any doubt, an increase in oral cortisol replacement is likely to do little harm, not increasing may push you towards adrenal crisis. Seek medical advice if unsure about how to increase oral doses, or for how long to keep the increase in place.
