HPA risk is duration and history, not the 20 mg stamp alone
Outside steroid tells ACTH to stand down. After enough days, the adrenal glands slack. Stop cold and a vomiting illness can look like adrenal crisis: hypotension, confusion, collapse.
For a first 20 mg five-day burst in an otherwise steroid-naive adult, clinically relevant suppression is unlikely. That is the SmPC majority sentence. It is not a promise for everyone.
The step-down mechanics live in 20 mg step-down. This glint is what happens to cortisol after the blister.
A first five-day 20 mg burst in a steroid-naive adult rarely needs a laminated card. Months of prednisolone this year plus a new 20 mg week does. Ask which one you are.
Inhaled high-dose steroid is still a load. Pre-op needs both the inhaler name and the oral 20 mg dates, not a vague 'I am on steroids'.
Vomiting so you cannot stand after a recent long course is 999 and the word prednisolone. Mild ache after a planned drop is a same-week call.
Do not inject a relative's hydrocortisone after a naive short burst because a forum scared you. Written plans only.
What is 999, not a GP email
Vomiting so you cannot keep tablets down, severe dizziness on standing, confusion, collapse, severe abdominal pain after a recent stop or during a taper: emergency. Say steroid and 20 mg out loud.
Mild ache two days after a planned drop is a same-week call, not an ambulance, unless you are going down.
Do not self-inject leftover hydrocortisone from a relative's Addison kit unless you have been trained and that is your written plan.
Morning cortisol is not a home kit
Random Facebook advice to 'check cortisol after five days of 20 mg' fills endocrine clinics with noise. Testing belongs to people with suggestive symptoms or a long exposure, ordered by the clinician, timed correctly.
A normal random cortisol on an afternoon after a burst does not prove the axis can meet a future surgical stress.
Do not delay indicated 20 mg because you are waiting for a private cortisol sticker.
Fever in the week after 20 mg
NICE notes that stress - infection, trauma, surgery - in the week after stopping a corticosteroid may still need extra cover if suppression is possible. A previously long-term patient who just finished a 20 mg 'top-up' sits in that week.
People on a current taper do not stop 20 mg because they have flu. They call for a sick-day increase. People who stopped a naive five-day pack usually do not need hydrocortisone theatre plans.
Carrying a steroid card is not drama if your last twelve months included weeks of 20 mg. It is how A and E notices you.
Dental and surgical lists after recent 20 mg
Tell the dentist and the pre-op nurse about every oral steroid course in the last year, not just today's 20 mg. They decide cover. You do not skip the history because the last pack was 'only a week'.
Elective surgery a few days after a four-week 20 mg course is a different conversation from a wisdom tooth six months after a five-day pack.
Full physiology and bone-glucose issues sit on the prednisolone frame.
- List start date, peak mg (if not 20), today's mg, stop date.
- Name inhaled steroids too.
- Keep one empty 20 mg blister in the bag for reconciliation.
High-dose inhalers plus a 20 mg pack
Inhaled steroid is still steroid. Frequent 20 mg packs on top of high-dose inhalers are how 'short oral courses' quietly become a chronic load.
The axis does not separate molecules as cleanly as the two boxes on the shelf. Tell pre-op about both.
Do not stop the inhaler because you started 20 mg unless told. That is how asthma relapses while you worry about HPA.
A spacer and a 20 mg pack in the same bag confuse hospital lists. Name each.
If this is pack three this year, the HPA glint applies even if each pack was five days of 20 mg.
A steroid card is not a taper sheet
The card tells A and E you have had systemic steroid. The taper sheet tells you today's milligram. People laminate the wrong one.
After a naive five-day 20 mg burst, a card is often unnecessary. After a long tail plus a 20 mg top-up, the card is the useful object.
Update the card when the 20 mg stops so the next ambulance does not treat you as still on 20 mg.
Digital photos of old cards from 2023 are how people get hydrocortisone they no longer need - or fail to get cover they do.
If you never got a card and last year was months of prednisolone, ask for one after this 20 mg burst. The burst is the reminder, not the whole exposure.
Who is already suppressed when the 20 mg starts
Anyone still tapering from a long course, anyone who finished months of prednisolone within the past year, anyone on evening doses, anyone who has had repeated 20 mg bursts for exacerbations.
Inhaled high-dose steroids plus frequent oral 20 mg packs add up. The oral burst is not the only exposure the axis has seen.
These people need a sick-day plan even when the current box is 'only 20 mg'. The milligram on today's tablet understates last year's load.
| History | After a 20 mg burst | Sick-day thought |
|---|---|---|
| First short burst, ≤3 weeks | Axis usually fine | Usual illness rules |
| Long course in the past year | Treat as vulnerable | Written extra cover |
| Still on a taper | Already suppressed | Do not stop for a cold |
The pre-op sentence after recent 20 mg
Oral prednisolone 20 mg, last daily dose [date], this course lasted [days], last year I also had [months or packs]. Inhaler: [name and dose]. That is the whole speech.
They decide cover. You do not double 20 mg the morning of surgery because a forum said so.
Dental lists count. A 'small extraction' after a four-week 20 mg course is still a stress.
If you never mention last year's long tail, they treat you as a naive five-day burst. That is the dangerous under-tell.
Bring the empty 20 mg box. Strength visible beats 'I was on steroids'.
Emergency surgery: say steroid as soon as you can speak. Minutes matter more than a perfect timeline.
Update the speech when the burst ends so next month's dentist does not think you are still on 20 mg.
If you cannot keep the 20 mg down
Vomiting on a current 20 mg course is missed steroid plus possible adrenal stress if you were already suppressed. Same-day advice. IM hydrocortisone is for people with a written plan, not for a first 20 mg burst in a naive adult.
Vomiting two days after a long-course stop is the crisis picture already named. 999 if you cannot stand or think clearly.
Do not replace vomited 20 mg with a neighbour's 5 mg 'to be gentle'. Wrong milligram, wrong plan.
Gastroenteritis week after a four-week 20 mg course is the NICE stress-cover week. Phone. Do not tough it out because the blister is empty.
Write the last swallowed 20 mg time on a card for the ambulance. Minutes matter more than adjectives.
If last year was long, this 20 mg burst is not isolated
Naive short bursts usually leave the axis intact. Repeat and long exposures do not. Write the history once and reuse it at every sick-day and every pre-op.
Confirm cover with the clinician who owns the steroids. This glint does not issue hydrocortisone.
Naive short 20 mg bursts usually leave the axis intact. Repeat packs and last year's long tail do not. Write the history once and reuse it at sick-day and pre-op.
A steroid card is a signal, not a taper. Update it when the 20 mg ends so the next ambulance does not treat you as still on twenty.
High-dose inhalers plus frequent 20 mg packs are a chronic load wearing a burst costume. Name both. Do not stop the inhaler because the oral pack started.
Dental lists count. A 'small extraction' a few days after a four-week 20 mg course is still a stress conversation. They decide cover. You do not double 20 mg the morning of the chair because a forum said so.
