1. What Dexamethasone Oral Solution is and what it is used for

The full name of your medicine is Dexamethasone 10mg/5ml Oral Solution. In this leaflet the shorter name Dexamethasone is used. This belongs to a group of medicines called Corticosteroids. Dexamethasone is a synthetic glucocorticoid (adrenocortical hormone).

Corticosteroids are hormones that are found naturally in your body that help to keep you healthy and well. Boosting your body with extra corticosteroid, such as Dexamethasone, is an effective way to treat various illnesses involving inflammation in the body. Dexamethasone lowers inflammation, which could otherwise go on making your condition worse. You must take this medicine regularly to get maximum benefit from it. Dexamethasone is used as a treatment of coronavirus disease 2019 (COVID-19) in adult patients with difficulty breathing and need of oxygen therapy.

Dexamethasone can be used in adults for:

  • replacing natural corticosteroids when levels have been reduced
  • treating swelling (inflammation) and certain allergies
  • reducing swelling of the brain which is not caused by a head injury
  • treating cancer
  • controlling how well your adrenal glands work. These are glands that are next to your kidneys
  • treating a number of different diseases of the immune system.

You may be using this medicine for a different reason. Ask your doctor why this medicine has been prescribed for you.

2. What you need to know before you take Dexamethasone Oral Solution
Do not take Dexamethasone:
  • if you are allergic to Dexamethasone or any of the other ingredients of this medicine (listed in section 6). The signs of an allergic reaction include a rash, itching or shortness of breath
  • if you have an infection (including fungal infections) that affects the whole body, unless you are being treated for the infection
  • if you have an infection with tropical worms
  • if you need to have a vaccination with a ‘live virus’ vaccine
  • if you have an ulcer in your stomach (peptic ulcer) or digestive tract area (duodenal ulcer)
  • to treat a serious lung disease called Acute Respiratory Distress Syndrome if you have had this problem for more than 2 weeks.

Do not take this medicine if any of the above apply to you. If you are not sure, talk to your doctor or pharmacist before taking Dexamethasone.

Mental health problems

Check with your doctor first:

  • if you have ever had severe depression or manic depression (bipolar disorder). This includes having had depression before while taking steroid medicines like Dexamethasone
  • if any of your close family has had these illnesses.
    If either of these applies to you, talk to your doctor before taking this medicine.

Mental health problems can happen while taking steroids like Dexamethasone (see also section 4: Possible side effects).

  • These illnesses can be serious.
  • 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 happen, they might need treatment.

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

  • if you have or are suspected of having pheochromocytoma (a tumor of the adrenal glands).

If any of the above apply to you (or you are not sure), talk to your doctor or pharmacist before taking Dexamethasone.

Taking a steroid medicine like Dexamethasone

Please tell your doctor, or anyone giving you treatment, that you are taking or have recently taken Dexamethasone, if any of the following things happen to you. This is because your dose of Dexamethasone may need to be increased during this time:

  • you get ill or develop an infection
  • you have an accident or other injury
  • you need to have any surgery, including dental work
  • you need to have a ‘live virus’ vaccine such as MMR, tuberculosis (TB), yellow fever or oral typhoid.

You should not stop taking any other steroid medications unless your doctor has instructed you to do.

Talk to your doctor, pharmacist or nurse before you take Dexamethasone.

General precautions regarding steroid use in specific diseases, masking infection, concomitant medicines etc. in line with current recommendations.

If you are living in the UK, you should always carry a blue ‘steroid card’, which gives clear guidance on the special care to be taken when you are taking this medicine. Show this to any doctor, dentist or person who may be giving you treatment. Even after your treatment has finished you must tell anyone who is giving you treatment that you have taken steroids in the past.

Chickenpox, shingles and measles:

While you are taking this kind of medicine, you should not come into contact with anyone who has chickenpox, shingles or measles if you have not had these illnesses. This is because you may need specialist treatment if you get these diseases. If you think you may have had exposure to any of these diseases, you should talk to your doctor immediately. You should also tell your doctor if you have ever had infectious diseases such as measles or chickenpox and if you have had any vaccinations for these conditions in the past.

Children and young people

This strength of dexamethasone is not recommended for use in children and young people. However if a child is taking this medicine at a doctors request, it is important that the doctor monitors their growth and development regularly. Dexamethasone should not be routinely given to premature babies with respiratory problems.

Older people

Some of the side effects of Dexamethasone may be more serious in older people. Your doctor may need to monitor you more closely for the following:

  • diabetes
  • getting infections
  • thinning of the skin
  • high blood pressure
  • thinning of the bones (osteoporosis)
  • low potassium levels in the blood (hypokalaemia).

Other medicines and Dexamethasone

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. This includes medicines you buy without a prescription, including herbal medicines. This is because Dexamethasone can affect the way some other medicines work. Also, some medicines can affect the way Dexamethasone works.

Some medicines may increase the effects of Dexamethasone and your doctor may wish to monitor you carefully if you are taking these medicines (including some medicines for HIV: ritonavir, cobicistat).

In particular, tell your doctor if you are taking any of the following:

  • live vaccines such as MMR, tuberculosis, yellow fever or oral typhoid
  • medicines to treat epilepsy, such as phenytoin, carbamazepine, primidone, phenobarbital and acetazolamide, also used for glaucoma
  • medicines to treat stomach problems, such as antacids, charcoal and carbenoxolone. You should leave at least two hours between taking these medicines and Dexamethasone
  • medicines that calm emotions or for sleeping, such as barbiturates or sulpiride
  • medicines that control pain or lower inflammation, such as aspirin or similar non-steroidal anti-inflammatory drugs (NSAIDs), such as indometacin, hydrocortisone, cortisone and other corticosteroids. You should be carefully monitored if you are taking NSAIDs at the same time as taking Dexamethasone because you are more likely to get stomach or gut ulcers
  • medicines used to treat diabetes such as insulin, metformin or sulfonylureas such as chlorpropamide
  • medicines used to lower potassium levels
  • medicines that help muscle movement in myasthenia gravis, such as neostigmine
