Patient leaflet - Hydrocortisone 5 mg tablets

1. What Hydrocortisone Tablets are and what they are used for

Hydrocortisone belongs to a group of medicines called steroids. Their full name is corticosteroids. These corticosteroids occur naturally in the body, and help to maintain health and well-being.

Boosting your body with extra corticosteroid (such as Hydrocortisone) is an effective way to treat various illnesses involving inflammation in the body. Hydrocortisone reduces this inflammation, which could otherwise go on making your condition worse. You must take this medicine regularly to get maximum benefit from it.

Hydrocortisone Tablets are used:

  • as replacement therapy in primary, secondary or acute adrenocortical insufficiency.
  • pre-operatively, and during serious trauma or illness in patients with known adrenal insufficiency or doubtful adrenocortical reserve.

Corticosteroid therapy should be used only when simpler proven diagnosis and therapy is not feasible or has failed (unless there is a life-threatening situation).

What is Adrenocortical insufficiency

The adrenal cortex, part of the adrenal glands situated near the kidneys, produces hormones called corticosteroids. Your adrenal cortex is not producing sufficient amounts of these corticosteroids to keep your body working properly. The hydrocortisone in your tablets replaces the natural steroids that you lack and helps to keep you healthy.

2. What you need to know before you take Hydrocortisone Tablets

Do not take Hydrocortisone Tablets:

  • If you are allergic to hydrocortisone or any of the other ingredients of this medicine (listed in section 6). An allergic reaction may be recognized as a rash, itching, swollen face or lips, or shortness of breath.
  • If you have thrush, Candida or any other fungal infection.
  • If you have any other infection.
  • If you have vaccinated recently or are going to have any vaccinations.

Warnings and precautions

Talk to your doctor before taking Hydrocortisone Tablets:

  • If you have ever had severe depression or manic-depression illness (bipolar disorder). This includes having had symptoms of depression in the past, including while taking steroid medicines like Hydrocortisone Tablets.
  • If any of your close family has had these illnesses.
  • If you have an over-active thyroid gland (hyperthyroidism).

Contact your doctor promptly if you experience muscle weakness, muscle aches, cramps and stiffness while using hydrocortisone. These can be symptoms of a condition called Thyrotoxic Periodic Paralysis, which may occur in patients with an over-active thyroid gland (hyperthyroidism) who are treated with hydrocortisone. You may need additional treatment to alleviate this condition.

Check with your doctor before taking this medicine if you currently have or have had any of the following:

  • tuberculosis
  • liver problems
  • kidney problems
  • high blood pressure
  • heart problems including recent heart attacks
  • diabetes (or a family history of diabetes)
  • osteoporosis (thinning of the bones)
  • glaucoma (increased pressure in the eye) or a family history of glaucoma.
  • epilepsy
  • stomach ulcers or other digestive problems
  • muscle weakness with steroids
  • existing or previous history of severe mood related disorders
  • thyroid problems
  • chicken-pox, shingles or measles
  • a weakened immune system
  • amoebic dysentery and an infestation of a gut worm (strongyloidiasis), it may be activated or become worse by Hydrocortisone tablets.

    You should see your doctor if you develop any new infections while taking these tablets.

    Taking hydrocortisone for a long period of time increases your chance of getting infections, which might be worse than normal and may very rarely be fatal.

    If you are taking or have recently taken (within the last 3 months) Hydrocortisone Tablets and you become ill, suffer stress, get injured or are about to have a surgical procedure you must tell your doctor immediately that you are taking Hydrocortisone Tablets. Your dose of hydrocortisone may need to be increased (or you may have to start taking it again for a short time) to prevent a sharp fall in blood pressure.

    If you have been on Hydrocortisone Tablets for longer than 3 weeks and wish to stop taking them, do not stop suddenly as this could result in a severe drop in blood pressure which could be fatal. Your doctor will advise on how to reduce the number of tablets you are taking.

    It is important to avoid exposure to people who have chicken pox, measles or shingles, especially if you have not already had these illnesses or are not sure if you have had them. Hydrocortisone increases the risk of a severe bout of chicken-pox. If exposed you must contact your doctor immediately.

    Children

    For children, it is important that a doctor monitors their growth and development at intervals throughout the treatment.

    If hydrocortisone is given to a prematurely born baby, monitoring of heart function and structure may be needed.

    Elderly

    Steroid should be used cautiously in elderly patients, particularly if long term, since adverse events are enhanced in old age, especially osteoporosis, hypertension, low potassium levels in the blood (hypokalaemia), diabetes, susceptibility to infection and thinning of the skin.

    Mental health problems while taking hydrocortisone

    Mental health problems can occur while taking steroids like hydrocortisone (see also section 4).

    • These illnesses can be severe.
    • Usually they start within a few days or weeks of starting the medicine.
    • They are more likely to happen at high doses.
    • Most of these problems go away if the dose is lowered or the medicine is stopped. However, if problems do occur they might need treatment.

Talk to a doctor if you (or someone taking this medicine) show any signs of mental health problems. This is particularly important if you are depressed or might be thinking about suicide. In a few cases, mental health problems have happened when doses are being lowered or the medicine stopped altogether.

Important - Steroid treatment card

All patients taking steroids for more than a few weeks should carry a ‘steroid treatment card’, which is available from your doctor or pharmacist. These cards have the details of the medicine you are taking. Always keep it with you and show it to any doctor or nurse treating you.

Driving and using machines

Hydrocortisone may have minor influence on your ability to drive and use machines. Extreme tiredness and episodes of short-lasting dizziness (vertigo) have been reported. Poorly treated or untreated adrenal insufficiency reduces your ability to concentrate and will affect your ability to drive and use machines. It is therefore important to take this medicine as directed by your doctor when driving or using machines. If you are affected do not drive or use machines, until you have discussed the issue with your doctor.

Hydrocortisone Tablets contains lactose

This medicine contains lactose (a kind of sugar). If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.

3. How to take Hydrocortisone Tablets

Always take this medicine exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.

The usual adult dose is: 20 to 30 mg a day, sometimes taken together with 4 to 6 g of sodium chloride or 50 to 300 micrograms of fludrocortisone.

Your doctor may want to prescribe more. The exact dose depends on your condition.

Use in Children

The dosage should be approximately 0.4 to 0.8 mg/kg given as two or three doses per day, adjusted to the needs of the individual child. Treatment should be limited to the minimum dosage for the shortest possible time.

Take the tablets by mouth exactly as the doctor, pharmacist or medicine label tells you to. Do not take more or less than your doctor has advised.

It is dangerous to reduce the dose of Hydrocortisone too quickly (e.g. post illness) as this may leave you without sufficient quantities of vital hormones. It may also cause withdrawal symptoms, including pains in muscles or joints, fever, and general discomfort. Your doctor will give you advice on reducing the amount of Hydrocortisone Tablets gradually if necessary.

If you take more Hydrocortisone than you should

If you take too much Hydrocortisone by mistake, contact your doctor as soon as possible.

If you forget to take Hydrocortisone

If you miss a dose, just carry on with the next one as normal. Do not take a double dose to make up for a forgotten one.

If you stop taking Hydrocortisone

Do NOT stop taking this medicine without talking to your doctor first – you may need to reduce the dose gradually.

If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
