Decadron for children is a corticosteroid (steroid) medicine that doctors often prescribe to reduce inflammation and swelling. Its best-known use is croup, where a single dose is usually given [3]. The doctor calculates the dose according to the child's weight and height. It is not given for a simple cough or cold without a medical assessment. Its short-term side effects are often mild, while long-term use requires follow-up and should never be stopped suddenly.
What is Decadron for children, and why does a doctor prescribe it?
Dexamethasone, sold under the brand name Decadron, belongs to the corticosteroid class. Corticosteroids are synthetic versions of a hormone the body produces naturally [2]. It is not an anabolic steroid (a performance-enhancing drug) of the kind some athletes use [2]. To learn the difference between the two types, read: Are anabolic steroids the same as cortisone?
The doctor prescribes it because it reduces inflammation and swelling in different parts of the body. It is available by prescription only. It comes as tablets or a liquid to be swallowed, and it may be given by injection in a hospital, usually [2]. You can find general drug information on the Decadron page in the drug directory. For an overview of this drug class, read: What are corticosteroids?
In Jordan, the Jordan Food and Drug Administration (JFDA) regulates drug registration and general drug prices. The decision to prescribe this medicine for your child rests with the doctor after examining your child.
Decadron for children and croup: why is a single dose usually given?
Croup is an inflammation of the vocal cords and windpipe (trachea). It causes a barking cough, a hoarse voice and difficulty breathing, and it is usually caused by a virus [5]. It often begins like a common cold, and then the vocal cords and windpipe swell and the symptoms appear. It may be accompanied by fever and high-pitched breathing sounds. Symptoms are usually worse at night and last about 3 to 5 days [5].
Children between 6 months and 3 years old are the most susceptible, and their symptoms may be more severe. Croup is more common in autumn and winter [5]. Most cases are mild and can be treated at home, but they rarely become serious or block breathing [5].
Because the core problem is swelling in the airway, doctors use a steroid to reduce this swelling. In croup, the child usually receives only one dose [3]. This does not mean that every barking cough needs this medicine. The doctor decides after assessing how severe the condition is. For details, read: Viral croup in children: when should you worry about a barking cough?
Be aware of the naming confusion: the word «الخناق» (khanaq) is also used for diphtheria, which is a completely different bacterial disease that is prevented by vaccination. You can find its details in the article: Diphtheria and its prevention by vaccination.
What other conditions might a doctor prescribe dexamethasone for in a child?
Dexamethasone is used for a range of conditions. According to medical sources, the most notable include:
- Severe allergic reactions (anaphylaxis) and severe skin diseases [2].
- Nausea and vomiting [2], including nausea that accompanies chemotherapy.
- Eye inflammation [2].
- Autoimmune diseases such as lupus [2].
- Reducing the effects of cancer treatment on the patient [2].
- Severe asthma attacks and some blood diseases and tumors within treatment protocols, according to the ClinicsJo drug guide.
In hospitals, it is also used in some serious infections [2]. These are specialist decisions made by the pediatrician or the specialist following the case, and the dose and duration vary from one case to another.
Eye and ear drops: the same ingredient, but a different use
Dexamethasone is also available as eye drops and ointments, and it is sometimes used to reduce redness, swelling and inflammation in the ear [1]. Do not substitute one dosage form for another. Each form has its own use, dose and specific warnings, and none of them should be given to a child except on the doctor's instructions.
One dose or a course? The difference in duration and follow-up
How Decadron is used in children depends on the reason it was prescribed. The following table summarizes the general differences and does not replace your doctor's instructions.
| Aspect | Single dose (e.g. croup) | Course of days or weeks |
|---|---|---|
| Purpose | Relieve acute swelling in the airway during a specific episode [3] | Control an inflammation or disease that needs more time |
| Number of doses | One dose determined by the doctor [3] | Depends on the disease, and may range from days to weeks or months [3] |
| Stopping | No gradual reduction needed | The doctor may gradually reduce the dose before stopping [3] |
| Side effects | Usually short-term | Their likelihood increases with longer duration and higher doses [4] |
| Follow-up | Review if symptoms do not improve or worsen | Regular monitoring of growth, weight and possibly blood sugar [4] |
During a long course, the doctor sometimes adjusts the dose, lowering it as symptoms improve and raising it if they return [3]. Therefore, do not change the dose or the number of times it is given yourself.
How is Decadron given to a child safely?
The usual dose, determined by the doctor or pharmacist for children, is calculated according to the child's weight and height [3]. It is always based on weight and on a doctor's prescription or pharmacist's guidance, and there is no general chart that suits all children. These are practical rules for parents:
- Follow the prescription exactly. Do not increase or decrease the dose, and do not change the number of times it is given. Do not give your child medicine left over from a sibling or another patient, since the medicine belongs to the person it was prescribed for [1].
- Measure liquids with the measuring device provided. Use the syringe or spoon that comes with the medicine, and ask the pharmacy for one if you do not have it. Do not use a kitchen spoon, because it does not measure the amount accurately [3].
- Tablets. Do not break or crush a tablet unless the doctor or pharmacist tells you to, and do not try to estimate half a dose yourself.
- Timing with food. For medicines taken daily, it is usually recommended to give them in the morning with or after breakfast, rather than on an empty stomach [3]. For croup, the doctor will direct you to the appropriate timing.
- Missed dose. Ask the pharmacist what to do, and do not give two doses together to make up for a missed one [3]. If the child vomits shortly after a dose, do not repeat it on your own; call the doctor.
- Do not stop the medicine suddenly after long use. After using it for more than two weeks, the doctor sets a gradual reduction schedule, because stopping abruptly may cause adrenal gland insufficiency, according to the ClinicsJo drug guide. Extreme tiredness, weakness, and body and joint pain may also appear [3]. For more, read: Corticosteroids: side effects and how to stop them safely.
- Store it safely. Keep it in its tightly closed container, away from children, heat and humidity, and not in the bathroom [1].
- Tell the doctor and pharmacist about everything your child takes, including medicines, vitamins, supplements and herbs [1]. For example, combining it with non-steroidal anti-inflammatory drugs such as ibuprofen increases the risk of stomach ulcers and bleeding, according to the ClinicsJo drug guide. Keep a written list of your child's medicines to show any doctor [1].
If the doctor prescribes eye or ear drops, wash your hands before use, do not touch the dropper tip to the eye or any surface, and follow the instructions on the package [1].
Is Decadron given for a common cough or cold?
No. Most colds and coughs are caused by viruses that go away on their own, and a steroid does not treat their cause. Cortisone weakens the immune system and may make infections more likely [2]. This is an additional reason to avoid using Decadron for children without a medical assessment.
Do not keep the medicine at home "just in case" of the next episode, and do not ask for a cortisone injection for a child because of a cough without the child being examined by a doctor. A barking cough with breathing difficulty needs an examination to determine the cause and severity, and then the doctor decides whether the medicine is necessary or not.
This applies to many medicines that seem familiar. For example, aspirin in children requires medical supervision in certain cases, as in Kawasaki disease.
What are the risks and side effects of Decadron for children?
Side effects depend on the dose and the duration of use, and they are less likely with lower doses [4]. Short-term use, such as a single dose for croup, is usually associated with mild and temporary effects, but parents should know what may appear.
Common short-term effects
- Sleep disturbance and mood changes, such as irritability, agitation or sudden crying [4].
- Indigestion and heartburn, which are relieved by giving the medicine with a meal or a snack [4].
- Increased appetite and weight gain [4].
- Raised blood sugar, which is more important in children with diabetes [4].
Effects with long-term use
Long-term use may slow the growth of children and adolescents, so the doctor monitors height and weight throughout the treatment period. Even with slowed growth, there does not appear to be a major effect on final adult height [4]. If the medicine continues for months, bones may weaken and vision problems may appear [4].
Other signs include facial swelling and rounding, with weight gain around the upper back or abdomen, which may indicate Cushing's syndrome [4]. Learn about it in the article: Cushing's syndrome: elevated cortisol and body changes. For information on what happens when the cortisol hormone is imbalanced: What happens when cortisol is out of balance?
Special precautions
- Infections: Tell the doctor immediately if your child gets an infection during treatment, or is exposed to someone with measles, chickenpox or shingles [2].
- Vaccines: Live vaccines are avoided during treatment with immune-suppressing doses, and the medicine weakens the response to vaccines, according to the ClinicsJo drug guide. Ask your doctor before any vaccination.
- Diabetes and other conditions: Children with diabetes need blood sugar monitoring and sometimes adjustment of their treatment [4].
- Allergy: Dexamethasone is contraindicated in people with an allergy to it, so tell the doctor about any previous allergies.
When should you see a doctor, and when should you go to the emergency room?
Call an ambulance (911) or go to the nearest emergency department immediately if:
- The child shows obvious difficulty breathing, very rapid breathing, or a high-pitched breathing sound even at rest.
- His or her lips, mouth, throat or tongue suddenly swell, or swallowing becomes difficult [4].
- The color of the skin, tongue or lips turns blue, gray or pale [4].
- The child appears limp and unresponsive as usual, or suddenly drowsy and confused [4].
- The child vomits blood or black or dark brown vomit [4].
See a doctor the same day if:
- Fever, chills, ear pain, pain when urinating, mouth sores or a wound that does not heal appear, as these may indicate an infection [4].
- There is severe vomiting, severe dizziness, muscle weakness, extreme tiredness or loss of appetite, as these may indicate a problem with the adrenal gland [4].
- Thirst and urination increase, or a fruity-smelling breath appears, which may indicate high blood sugar [4].
- Red or black stools, unusual bruising or bleeding, or changes in vision appear [4].
- Mood disturbance, hallucinations or a clear change in behavior becomes severe [4].
- The child took a larger dose than prescribed and new symptoms appeared, such as stomach pain or difficulty sleeping [3].
If you suspect an overdose, take the medicine package, the leaflet, and any other medicines your child takes with you [3].
How do you find the right doctor or clinic in Jordan?
For any barking cough or breathing difficulty, or before starting any steroid course, the pediatrician is the first point of reference. If your child has a chronic condition such as asthma, diabetes or an immune disorder, a specialist suited to the condition may follow them in coordination with the pediatrician. For an initial assessment, you may visit Ministry of Health centers and Mother and Child Health centers in the governorates.
The ClinicsJo directory lets you search by specialty and governorate, read doctors' and clinics' profiles, and contact them or book an appointment where the profile allows. To get started, you can browse the Pediatric Healthcare Doctors Directory in Amman. ClinicsJo does not provide online consultations or medical prescriptions, and it does not rank doctors by medical quality.
What to check in a profile
- The specialty (pediatrics or the appropriate subspecialty), the clinic's location and governorate.
- Working hours and the available method of contact or booking.
- Whether it accepts urgent cases or only appointments. For emergencies, go to the emergency department, not the clinic.
Questions to ask the doctor or pharmacist
- Why does my child need Decadron now, and what are the alternatives if any exist?
- Is it a single dose or a course? For how many days? Will the medicine be gradually reduced?
- When and how should I give it, and what should I do if he or she vomits or I forget a dose?
- What side effects should I monitor, and when should I come back to you?
- Does it interact with my child's current medicines or upcoming vaccinations?
If your child may need cortisone for repeated periods, ask the doctor for a written plan that includes the dose, the duration and warning signs.
Frequently asked questions
Is Decadron for children safe?
It is usually safe when the doctor prescribes it at the dose and duration appropriate for the child's condition, especially in short-term use such as a single dose for croup. Risks increase with high doses or long-term use, so it is not given without a prescription, the prescribed dose should not be exceeded, and you should consult the doctor if any worrying symptom appears.
Should I give Decadron to my child at home for a barking cough?
Do not give it on your own. A barking cough with breathing difficulty or a high-pitched breathing sound needs a medical examination to assess the severity of the condition, and the doctor may decide on a single dose. If obvious breathing difficulty or blue lips appear, call an ambulance at 911 or go to the emergency department immediately.
How many days is dexamethasone given to a child?
This depends on the reason it was prescribed. For croup it is usually a single dose, while for other conditions it may be a course lasting days, weeks or longer. Only the doctor determines the duration, and do not stop the medicine or extend its duration on your own, especially if the course has been long.
What are the common side effects of Decadron in children?
The most common are sleep disturbance, mood swings, indigestion and increased appetite. Giving the medicine with food relieves indigestion. Blood sugar may also rise. With long-term use, growth may slow, so the doctor monitors height and weight. Inform the doctor if the symptoms are severe or do not go away.
Can dexamethasone be stopped suddenly?
After a single dose or a very short use, a gradual reduction is usually not needed. However, if the medicine continues for more than two weeks, it must not be stopped suddenly, because this may cause severe tiredness, weakness and adrenal gland insufficiency. The doctor sets a schedule for gradually lowering the dose.
Does Decadron affect a child's vaccinations?
The medicine may weaken the body's response to vaccines, and live vaccines are avoided during treatment with immune-suppressing doses. Therefore, tell the doctor about any steroid course before any vaccination date, and ask about the appropriate timing. Also tell the doctor if your child has been exposed to someone with chickenpox or measles.
