Informazioni sull'idrocortisone
Tipo di medicinale | A corticosteroid medicine |
Utilizzato per | Cortisol replacement treatment in people with Addison's disease or following surgical removal of the adrenal glands |
Chiamato anche | Hydventia®, Plenadren® (modified-release tablets), Efmody® (modified-release capsules), Alkindi® (granules) |
Disponibile come | Tablets, soluble tablets, modified-release tablets and capsules, granules in capsules for opening |
Hydrocortisone belongs to a group of medicines called corticosteroids. It is sometimes referred to simply as an oral steroid. It is used as a replacement treatment for people whose adrenal glands are not producing as much of the steroid hormones (such as cortisol) as they normally do. This can happen in a condition known as adrenal insufficiency, or malattia di Addison. It also happens in people who have had surgery to remove their adrenal glands and who therefore no longer make their own natural steroid hormones. These hormones are vital for your body and if you do not have enough of them, you can become very unwell.
Hydrocortisone is usually prescribed alongside another replacement medicine called fludrocortisone. Fludrocortisone is a substitute medicine for one of the other vital hormones that are no longer being made in people with adrenal insufficiency.
Before taking hydrocortisone tablets or capsules
Torna ai contenutiSome medicines are not suitable for people with certain conditions, and sometimes a medicine can only be used if extra care is taken. For these reasons, before you start taking hydrocortisone it is important that your doctor knows:
Se hai la pressione alta.
Se hai avuto un infarto o se hai altri problemi cardiaci.
Se hai problemi con il funzionamento del tuo fegato, o se hai problemi con il funzionamento dei tuoi reni.
If you (or a close family member) have either diabetes (diabetes mellitus) or an eye condition called glaucoma.
If you have any of the following conditions: an underactive thyroid gland, 'thinning' of the bones (osteoporosis), epilepsy, a condition causing muscle weakness (called myasthenia gravis), a stomach ulcer, or an inflammatory bowel disorder.
Se hai mai avuto un problema di salute mentale.
If you are pregnant or breastfeeding. (Oral steroids like hydrocortisone can be taken while you are expecting or breastfeeding; however, it is important that your doctor knows about the baby.)
If you have any kind of infection at the moment, or if you have ever had tuberculosis (TB).
If you have ever had an unwanted blood clot in an artery or a vein.
Se hai recentemente ricevuto, o stai per ricevere, qualsiasi vaccinazione.
Se stai assumendo altri medicinali, inclusi quelli disponibili per l'acquisto senza prescrizione, così come medicinali a base di erbe e complementari.
Se hai mai avuto una reazione allergica a un medicinale, o se hai mai sviluppato dolori muscolari dopo aver assunto un medicinale steroideo.

How to take hydrocortisone tablets or capsules
Torna ai contenutiBefore starting the treatment, read the manufacturer's printed information leaflet from inside the pack and any additional information you are given by your doctor. These will give you more information about hydrocortisone and will also provide you with a full list of side-effects which you could experience from taking it.
Your doctor or pharmacist will tell you how many tablets to take and when to take them. This information will also be printed on the label of the packet of tablets to remind you about what was said to you. It is important that you take hydrocortisone exactly as your doctor tells you to. As a guide:
If you are taking immediate-release tablets (called simply 'Hydrocortisone tablets'), it is likely that you will be prescribed two or three doses to take each day. It is usual for your morning dose to be larger than the other doses. Take the tablets just after eating a meal, or alternatively with a snack.
If you have been prescribed a brand of tablet called Plenadren®, this is a tablet which releases hydrocortisone to your body throughout the day. It is usual to take one dose a day, 30 minutes before your breakfast. Swallow the tablet whole (this means do not break, crush, or chew it), with a drink of water. Do not drink grapefruit juice if you are taking Plenadren® because it will interfere with the way the tablets work.
If you (or your child) have been prescribed granules in capsules for opening (Alkindi®) follow the manufacturer's instructions closely. Do not swallow the capsule. Carefully open the capsule and place the granules either directly onto the tongue, onto a spoon or onto some soft food like yoghurt or apple sauce. Make sure the capsule is empty of granules. Have a drink of water or milk after swallowing the granules.
Try to take your doses at the same time of day each day, as this will help you to remember to take hydrocortisone regularly. If you forget to take a dose, take it as soon as you remember (unless it is nearly time for your next dose, in which case leave out the missed dose). Do not take two doses together to make up for a forgotten dose.
Continue to take hydrocortisone tablets regularly each day - it is vital for your well-being. Hydrocortisone replacement treatment is almost always lifelong.
Ottenere il massimo dal tuo trattamento
Torna ai contenutiYou will be given a 'Steroid Treatment Card' which says that you are on steroids and contains some important advice for you. It is important that you read this card and carry it with you at all times. It also contains details about your dose, how long you have been taking hydrocortisone and who prescribed it for you. Please make sure that this information is kept up to date. If you are due to have an operation or dental treatment, or if you are having any treatment for an injury, please tell the person carrying out the treatment that you are taking hydrocortisone and show them your treatment card.
Cerca di mantenere i tuoi appuntamenti regolari con il tuo medico. Questo è per permettere al tuo medico di controllare i tuoi progressi. Il tuo medico vorrà che tu faccia esami di tanto in tanto per assicurarsi che tu rimanga libero da alcuni degli effetti collaterali indesiderati del trattamento.
It is important that if you become ill you make an appointment to see your doctor straightaway. Also, if you come into contact with anyone who has measles, shingles or chickenpox (or anyone who suspects they might have them), you should contact your doctor for advice as soon as possible.
Make sure you get your next supply of tablets well in advance so that you never run out. People with Addison's disease are entitled to free prescriptions.
Some vaccines are not suitable for you while you are being treated with hydrocortisone. If you need any immunisations, make sure you mention that you are taking hydrocortisone.
If you buy any medicines 'over the counter', please check with a pharmacist that they are suitable for you to take alongside hydrocortisone.

Il cortisone può causare problemi?
Torna ai contenutiAlong with its useful effects, hydrocortisone can cause unwanted side-effects which your doctor will discuss with you. The benefits of taking hydrocortisone usually outweigh the side-effects; however, they can sometimes be troublesome. Although not everyone experiences side-effects, and some will improve as your body adjusts to the new medicine, speak with your doctor or pharmacist if you become concerned about any of the following:
Common hydrocortisone side-effects | Cosa posso fare se sperimento questo? |
Ritenzione idrica che causa gonfiore a piedi e caviglie | Quando possibile, siediti con i piedi sollevati |
Tummy (abdominal) pain, indigestion, feeling sick (nausea) | Eat little and often. Stick to simple or bland foods. If you are sick and there is blood present, you must speak with your doctor straightaway |
Muscle weakness or feeling tired | Se ciò accade, non guidare e non utilizzare strumenti o macchinari finché non ti senti più sveglio |
Mood or behavioural changes, especially at the beginning of treatment | If you become confused or irritable, or start having worrying thoughts about harming yourself, speak with your doctor straightaway |
Difficulties sleeping, headache, increased weight, and irregular periods in women | Se uno di questi diventa problematico, parla con il tuo medico |
Increased risk of getting an infection | If you become ill, make an appointment to see your doctor straightaway |
Long-term treatment with hydrocortisone may cause other unwanted effects | Se hai sintomi che ti preoccupano, dovresti fissare un appuntamento con il tuo medico per un consiglio |
For more information about side-effects which are possible when a corticosteroid is taken long-term, please see the separate leaflet called Steroidi orali.

Domande frequenti
What is the difference between immediate-release tablets and modified-release tablets like Plenadren®?
Immediate-release tablets, simply called 'Hydrocortisone tablets,' are usually taken two or three times a day, with a larger dose in the morning. Modified-release tablets like Plenadren® release hydrocortisone into your body throughout the day, so you generally only take one dose daily, 30 minutes before breakfast. It's important to swallow Plenadren® tablets whole and avoid grapefruit juice, as it can affect how the medicine works.
Why is it important to carry a 'Steroid Treatment Card'?
You will be given a 'Steroid Treatment Card' because it provides important advice about your hydrocortisone treatment. It includes details about your dosage, how long you've been taking it, and who prescribed it. Carrying this card means that if you need an operation, dental work, or treatment for an injury, you can inform the healthcare professional that you are taking hydrocortisone, which is vital for your care.
Can I take other medications, including over-the-counter remedies, while on hydrocortisone?
If you are taking hydrocortisone, your doctor needs to know about any other medicines you are currently using, including those purchased without a prescription, as well as herbal and complementary medicines. When you wish to buy any over-the-counter medicines, you should always check with a pharmacist to ensure they are safe to take alongside hydrocortisone.
What should I do if I become unwell or come into contact with someone who has an infection like chickenpox?
It is important that if you become ill, you make an appointment to see your doctor straightaway. Also, if you come into contact with anyone who has measles, shingles, or chickenpox (or anyone who suspects they might have them), you should contact your doctor for advice as soon as possible.
Will I need to take hydrocortisone for the rest of my life?
Yes, hydrocortisone replacement treatment is almost always lifelong for conditions like Addison's disease or after adrenal gland removal. It is vital for your well-being, and you should continue to take your tablets regularly each day as prescribed by your doctor.
Are there any specific instructions for giving hydrocortisone granules to a child?
If you or your child have been prescribed granules in capsules for opening (Alkindi®), it's important not to swallow the capsule. You should carefully open the capsule and place the granules directly onto the tongue, a spoon, or soft food like yoghurt or apple sauce. After swallowing the granules, have a drink of water or milk. Make sure the capsule is empty. Always follow the manufacturer's instructions closely.
What should I do if I experience symptoms like mood changes or thoughts of harming myself?
If you experience mood or behavioural changes, especially at the beginning of treatment, such as becoming confused or irritable, or if you start having worrying thoughts about harming yourself, you should speak with your doctor straightaway.
