Information Standard quality markThis leaflet has been written specifically for parents and carers about the use of this medicine in children. The information may differ from that provided by the manufacturer. Please read this leaflet carefully. Keep it somewhere safe so that you can read it again.

This medicine is for your child. Never give it to anyone else. It may harm them even if they have the same symptoms as your child.

Name of drug

Fludrocortisone acetate
Brand names:

Why is it important for my child to take this medicine?

Fludrocortisone is a type of steroid medicine called a mineralocorticoid. If your child’s adrenal glands have been removed or are not working properly (this is sometimes called adrenal insufficiency), they need to take fludrocortisone to replace the hormones normally produced by the adrenal glands. They may also need to take another steroid medicine called hydrocortisone. Fludrocortisone is also used to reduce potassium in children with poor kidney function.

What is fludrocortisone available as?

  • Tablets: 100 micrograms fludrocortisone acetate

When should I give fludrocortisone?

  • Fludrocortisone is usually given once each day. This is usually in the morning.

Give the medicine at about the same time each day so that this becomes part of your child’s daily routine, which will help you to remember.

How much should I give?

Your doctor will work out the amount of fludrocortisone (the dose) that is right for your child. The dose will be shown on the medicine label.

It is important that you follow your doctor’s instructions about how much to give.

How should I give it?

TabletsTablets should be swallowed with a glass of water, milk or juice. Your child should not chew the tablet.

You can crush the tablet and mix it with a small amount of soft food such as yogurt, honey or jam. Make sure your child swallows it straight away, without chewing.

Your doctor may prescribe a dose that means you need to cut a tablet in half. To help give a half tablet, the tablets are scored. Ideally, use a tablet splitter, which you can get from your doctor or pharmacist. If this is not available, use a sharp knife. You can store the half tablet and give it to your child for the next dose unless your doctor has told you not to.

When should the medicine start working?

The medicine should start working straight away but you may not see much difference in your child.

What if my child is sick (vomits)?

  • If your child is sick less than 30 minutes after having a dose of fludrocortisone, give them the same dose again.
  • If your child is sick more than 30 minutes after having a dose of fludrocortisone, you do not need to give them another dose. Wait until the next normal dose.

What if I forget to give it?

Give the missed dose when you remember during the day, as long as this is at least 12 hours before the next dose is due.

Never give a double dose of fludrocortisone.

What if I give too much

It may be dangerous to give too much fludrocortisone.

If you think you may have given your child too much fludrocortisone, contact your doctor or NHS Direct (0845 4647 in England and Wales; 08454 24 24 24 in Scotland) or take your child to hospital. Take the medicine container or packaging with you, even if it is empty. This will be useful to the doctor. Have the medicine or packaging with you if you telephone for advice.

Are there any possible side-effects?

We use medicines to make our children better, but sometimes they have other effects that we don’t want (side-effects).

Side-effects you must do something about

Fludrocortisone can cause mood swings. Tell your doctor straight away if your child:

  • has frequent high moods
  • feels depressed, including thinking about suicide
  • feels anxious, has problems sleeping, seems confused, or has difficulty remembering things, says they are seeing or hearing things that do not exist.

Fludrocortisone can cause ulcers in the stomach. Tell your doctor straight away if your child has severe abdomen pain.

Other side-effects you need to know about
  • Your child may feel dizzy or light-headed or have headaches. If this happens often, contact your doctor to check your child’s blood pressure, as it may be too high.
  • Your child may get salt or water retention which can cause swelling in the hands and feet or puffiness of the eyes. Contact your doctor if you are worried.
  • Your child may be more hungry than usual or have indigestion, feel sick (nausea) or be sick (vomit). They may also feel tired or weak. This should get better after a week or so, but contact your doctor if you are worried.
  • Fludrocortisone can slow growth. Your doctor will check your child’s growth and development. If you have any concerns, talk to your doctor.
  • Your child may be at more risk of severe infections. They should stay away from anyone with an infection (such as chicken pox, shingles, measles) if they have not had these illnesses or have not been vaccinated.
  • If your child is unwell and you are worried about an infection, contact your doctor straight away.
  • Your child’s skin may become thinner, and heal more slowly than usual. Acne (spots) may become worse or your child may develop mouth ulcers or thrush (candidiasis). If you are concerned, contact your doctor.
  • Your child may develop problems with their hip bones, or their bones may become weaker (osteoporosis). The muscles around the hips and shoulders may also become weaker. If your child has any difficulty walking or moving around, contact your doctor.
  • Occasionally, fludrocortisone causes diabetes. If your child seems more thirsty than normal, needs to pass urine (wee) often, or starts wetting the bed at night, contact your doctor.

There may, sometimes, be other side-effects that are not listed above. If you notice anything unusual and are concerned, contact your doctor.

Can other medicines be given at the same time as fludrocortisone?

  • You can give your child medicines that contain paracetamol or ibuprofen, unless your doctor has told you not to.
  • Fludrocortisone should not be taken with some medicines that you get on prescription. Tell your doctor and pharmacist about any other medicines your child is taking before giving fludrocortisone.
  • Check with your doctor or pharmacist before giving any other medicines to your child. This includes herbal or complementary medicines.

Is there anything else I need to know about this medicine?

In a very few cases, children become very unwell when they stop or reduce the amount of any steroid medicine they are taking, including fludrocortisone (in high doses). If you are at all worried about this, contact your doctor.

  • The use of steroids in children receives a lot of bad press. However, use of fludrocortisone for hormone replacement provides a lot of benefit, and is unlikely to cause any long-term harm as long as you use the medicine as your doctor has told you to. If you are at all worried, talk to your doctor or pharmacist.
  • If your child has been taking fludrocortisone for longer than 3 weeks, they should not usually stop taking the medicine suddenly because they will get withdrawal symptoms: they will feel unwell, dizzy and thirsty and may be sick (vomit). Your doctor will give you more advice.
  • If your doctor wants to stop fludrocortisone, they will reduce the dose gradually before stoppng it completely. Make sure you follow your doctor’s instructions.
  • If your child is due to have an immunisation (vaccination), tell the nurse or doctor that your child is taking fludrocortisone.

Keep all your clinic appointments, as your doctor or nurse needs to check how your child is doing.

General advice about medicines

  • Try to give medicines at about the same times each day, to help you remember.
  • If you are not sure a medicine is working, contact your doctor but continue to give the medicine as usual in the meantime. Do not give extra doses as you may do harm.
  • Only give this medicine to your child. Never give it to anyone else, even if their condition appears to be the same, as this could do harm.

If you think someone else may have taken the medicine by accident, contact your doctor straight away.

  • Make sure that you always have enough medicine. Order a new prescription at least 2 weeks before you will run out.
  • Make sure that the medicine you have at home has not reached the ‘best before’ or ‘use by’ date on the packaging. Give old medicines to your pharmacist to dispose of.

Where I should keep this medicine?

  • Keep the tablets in a fridge. Make sure the bottle is tightly closed so that moisture cannot get in.
  • Make sure that children cannot see or reach the medicine.
  • Keep the medicine in the container it came in.
