1. What Alkindi is and what it is used for

Alkindi contains the active substance hydrocortisone. Hydrocortisone belongs to a group of medicines known as corticosteroids.

Hydrocortisone is a synthetic version of the natural hormone cortisol. Cortisol is made by the adrenal glands in the body. Alkindi is for use in children and adolescents aged birth to 18 years when the body is not making enough cortisol, because part of the adrenal gland is not working (adrenal insufficiency, often caused by an inherited condition called congenital adrenal hyperplasia).

2. What you need to know before you give Alkindi
Do not give Alkindi:
  • If your child is allergic to hydrocortisone or any of the other ingredients of this medicine (listed in section 6).
  • If your child has difficulties swallowing food, or is a premature baby who cannot yet be fed by mouth.

Warnings and precautions

Talk to your endocrinologist or pharmacist before giving Alkindi:

  • if your child is unwell or has an infection. The endocrinologist may need to increase the dose of Alkindi temporarily; talk to your endocrinologist if your child is unwell.
  • if your child has an adrenal crisis. If your child is vomiting or seriously unwell, your child may need an injection of hydrocortisone. Your endocrinologist will train you how to do this in an emergency.
  • if your child is due for a vaccination. Taking Alkindi should not stop your child being vaccinated. Let your endocrinologist know when your child is due for vaccinations.
  • if your child is due for an operation. Let the anaesthetist know your child is receiving Alkindi before your child has their operation.
  • if your child is being fed through a nasogastric tube. Alkindi granules are not suitable for giving through a nasogastric tube as the granules may block the tube.
  • when your child is changing to Alkindi from another hydrocortisone preparation.
    Differences between hydrocortisone preparations when changing to Alkindi may mean your child could be at risk of receiving an incorrect dose of hydrocortisone in the first week after switching to Alkindi. This may lead to a risk of adrenal crisis. You should watch your child carefully in the week after changing to Alkindi. Your doctor will tell you when you can increase the dose of Alkindi if there are symptoms of adrenal crisis such as unusual tiredness, headache, a raised or low temperature or vomiting. If this happens medical attention should be sought right away.

You should not stop giving Alkindi without checking with your endocrinologist as this could make your child seriously unwell very quickly.

As Alkindi is replacing the normal hormone your child lacks, side effects are less likely, however:

  • Too much Alkindi can affect your child’s growth, so your endocrinologist will adjust the dose depending on your child’s size and monitor your child’s growth carefully. Let your endocrinologist know if you are worried about your child’s growth (see section 4).
  • Too much Alkindi can affect your child’s bones so your endocrinologist will adjust the dose depending on your child’s size.
  • Some adult patients taking hydrocortisone became anxious, depressed or confused. It is not known if this would happen with children, but tell your endocrinologist if your child develops any unusual behaviour after starting Alkindi (see section 4).
  • In some patients with allergies to other medicines, allergy to hydrocortisone has been seen. Tell your endocrinologist straight away if your child has any reaction like swelling or shortness of breath after being given Alkindi.
  • Contact your endocrinologist if your child has blurred vision or other visual disturbances.

Alkindi granules can sometimes appear in a child’s nappy or poo after taking Alkindi. This is because the centre of the granule is not absorbed in the gut after it has released the medicine. This does not mean the medicine will not work and you do not need to give your child another dose.

Other medicines and Alkindi

Tell your doctor or pharmacist if your child is taking, has recently taken or might take any other medicines.

Some medicines can affect the way that Alkindi works, and may mean that your endocrinologist needs to alter your child’s dose of Alkindi.

Your endocrinologist may need to increase your child’s dose of Alkindi if your child take certain medicines, including:

  • Medicines used to treat epilepsy: phenytoin, carbamazepine, and oxcarbazepine.
  • Medicines used to treat infections (antibiotics): rifampicin and rifabutin.
  • Medicines called barbiturates, which can be used to treat convulsions (including phenobarbital and primidone).
  • Medicines used to treat AIDS: efavirenz and nevirapine.

Your endocrinologist may need to decrease your child’s dose of Alkindi if your child take certain medicines, including:

  • Medicines used to treat fungal diseases: itraconazole, posaconazole, and voriconazole.
  • Medicines used to treat infections (antibiotics): erythromycin and clarithromycin.
  • Medicine used to treat human immunodeficiency virus (HIV) infection and AIDS: ritonavir.

Alkindi with food and drink

Some food and drink may affect the way Alkindi works, and may need your doctor to decrease your child’s dose. These include:

  • Grapefruit juice.
  • Liquorice.

Pregnancy, breast-feeding and fertility

Hydrocortisone can be used during pregnancy and breast-feeding when the body is not making enough cortisol.

There is no information on any effects of Alkindi on fertility.

Driving and using machines

Alkindi has no influence on a child’s ability to perform skilled tasks (e.g. riding a bicycle) or using machines.

3. How to give Alkindi

Always use this medicine exactly as your doctor, nurse or pharmacist has told you. Check with them if you are not sure.

Your endocrinologist will decide on the right dose of Alkindi based on your child’s weight or size (body surface area) and then adjust the dose of Alkindi as your child grows. During illnesses, around the time of surgery and during times of serious stress, your endocrinologist may recommend additional doses of Alkindi and may also advise that your child receives another corticosteroid instead of, or as well as, Alkindi.

How to give this medicine

The granules should be given into the mouth and should not be chewed. The capsule shell should not be swallowed but should be carefully opened as follows:

How to open the Alkindi capsule and give the granules

1 Hold capsule so that the text is at the top and tap the capsule to make sure the granules are at the bottom
2 Gently squeeze the bottom of the capsule
3 Twist off the top of the capsule
4 Pour all granules out of capsule

Either pour all the granules directly onto the child's tongue

OR pour all the granules directly onto a spoon and place them in the mouth

OR for children who are able to take soft food, sprinkle the granules onto a spoonful of cold or room temperature soft food (such as yoghurt or fruit puree) and give immediately

Whichever method is used, tap the capsule to ensure all the granules are removed.

If you give the granules directly into the mouth, give a drink (e.g. water, milk, breast-milk or formula-milk) immediately after administration to help ensure all granules are swallowed.

If you give the granules sprinkled onto a spoonful of soft food, administer immediately (within 5 minutes) and do not store for future use.

DO NOT add the granules to liquid before administration as this can result in less than the full dose being given, and might also dissolve the taste masking of the granules allowing the bitter taste of hydrocortisone to become apparent.

Warning Alkindi granules come in a capsule that must be opened before use, discard the empty capsule after use out of reach of children. Do NOT swallow the capsule — small children may choke.

If you give more Alkindi than you should

If you give your child more Alkindi than you should, contact your endocrinologist or pharmacist for further advice as soon as possible.

If you forget to give Alkindi or your child had incomplete dose

If a full dose of Alkindi is missed, give your child that dose as soon as you remember, as well as their next dose at the usual time, even if this means that your child receives two doses at the same time.

Contact your healthcare provider if your child regurgitates, vomits or spits out most of the granules in a dose administered, as a repeat dose may be required to avoid adrenal insufficiency.

If you stop giving Alkindi

Do not stop giving your child Alkindi without asking your endocrinologist first. Stopping the medicine suddenly could quickly make your child very unwell.

If your child becomes unwell

Tell your endocrinologist or pharmacist if your child becomes ill, suffers severe stress, gets injured or is about to have surgery because your endocrinologist may need to increase the dose of Alkindi in these circumstances (see section 2).

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

4. Possible side effects
