The name of your medicine is Dexamethasone Tablets (called dexamethasone throughout this leaflet). Dexamethasone is a synthetic glucocorticoid (adrenocortical hormone) with an effect on metabolism, electrolyte balance and tissue functions.
Dexamethasone is used for:
Swelling of the brain caused by brain tumours, neurosurgery, bacterial inflammation of the lining of the brain (meningitis), brain abscess.
Severe acute asthma attack
Initial treatment of extensive acute severe skin diseases, such as erythroderma, pemphigus vulgaris or acute eczema.
Treatment of rheumatic systemic diseases (rheumatic diseases that can affect internal organs), such as systemic lupus erythematosus.
Severely progressive form of active rheumatic joint inflammation (rheumatoid arthritis), e.g. forms that quickly lead to joint destruction and/or when tissue outside the joints is affected.
Severe infectious diseases with intoxication-like conditions (like tuberculosis, typhoid fever), only in addition to appropriate anti-infective therapy.
Supportive treatment for malignant tumours.
Treatment of coronavirus disease 2019 (COVID-19) in adult and adolescent patients (aged 12 years and older with body weight at least 40 kg) with difficulty breathing and need of oxygen therapy.
Hormone replacement therapy: in reduced or failure of adrenal function (adrenogenital syndrome) in adulthood.
Talk to your doctor, pharmacist or nurse before taking dexamethasone:
If you are taking other steroid medicines, you should not stop taking any other steroid medications unless your doctor has instructed you to do.
General precautions regarding steroid use in specific diseases, masking infection, concomitant medicines etc. in line with current recommendations.
Talk to your doctor before taking dexamethasone if you have or are suspected of having pheochromocytoma (a tumour of the adrenal glands).
Treatment with glucocorticoids can lead to underactive adrenal cortex (insufficient endogenous production of glucocorticoids), depending on the dose and duration of treatment, this can last for several months and in individual cases longer than a year after discontinuation of treatment.
If you experience particular physical stress (such as illnesses with fever, accidents or surgery, childbirth, etc.) during treatment with glucocorticoids, you should tell your doctor or inform the emergency doctor about your ongoing treatment.
A temporary increase in the daily dose of dexamethasone may be required. Even in case of continued underactive adrenal cortex after the end of treatment, the administration of glucocorticoids may be necessary in physical stress situations. Therefore, during long-term treatment with dexamethasone, your doctor should give you a steroid card, which you should always carry with you.
In order to avoid treatment-induced acute adrenal insufficiency, when treatment discontinuation is intended, your doctor will determine a dose-reduction plan, which you should follow.
By suppressing the body’s immune system, treatment with dexamethasone can lead to an increased risk of bacterial, viral, parasitic, opportunistic and fungal infections. It can mask the signs and symptoms of an existing or a developing infection, making it more difficult to recognize them. Latent infections can be reactivated.
In the following illnesses, treatment with dexamethasone tablets should only be started if your doctor considers it essential. If necessary, medications that act against the pathogens should also be taken:
The following diseases should be specifically monitored during concomitant treatment with dexamethasone and treated according to the requirements:
If you experience blurred vision or other visual disturbances, contact your doctor.
Because of the risk of intestinal wall perforation, dexamethasone may only be taken if there are compelling medical reasons and under appropriate monitoring:
Signs of peritoneal irritation after gastrointestinal perforation may be absent in patients receiving high doses of glucocorticoids.
In patients with diabetes, metabolism should be checked regularly, the possibility of a higher need for medicines for the treatment of diabetes (insulin, oral antidiabetics) should be taken into consideration.
Patients with severe high blood pressure and/or severe heart failure should be carefully monitored, as there is a risk of deterioration.
High dose can lead to slowing of the heartbeat.
Severe anaphylactic reactions (overreaction of the immune system) may occur.
The risk of tendon pain, tendon inflammation and tendon rupture is increased when fluoroquinolones (certain antibiotics) and dexamethasone are administered together.
During the treatment of a particular form of muscle paralysis (myasthenia gravis), symptoms may worsen at the beginning.
Vaccinations with vaccines from killed pathogens (inactivated vaccines) are generally possible. However, it should be noted that the immune response and thus vaccine may be compromised at higher doses of corticoids.
Viral diseases (such as measles, chickenpox) can be particularly severe in patients treated with dexamethasone. Patients with a compromised immune system who have not had measles or chickenpox yet are particularly at risk. If these patients have contact with people infected with measles or chickenpox during treatment with Dexamethasone tablets, they should immediately contact their doctor, who will introduce a preventative treatment if necessary.
Symptoms of tumour lysis syndrome, such as muscle cramping, muscle weakness, confusion, visual loss or disturbances and shortness of breath, in case you suffer from haematological malignancy.
Contact your doctor if you experience blurred vision or other visual disturbances.
Treatment with this medicine may cause pheochromocytoma crisis, which can be fatal. Pheochromocytoma is a rare tumour of the adrenal glands. Crisis can occur with the following symptoms: headaches, sweating, palpitations, and hypertension. Contact your doctor immediately if you experience any of these signs.
Due to the risk of growth inhibition, dexamethasone should only be administered in children for compelling medical reasons, and during long-term treatment growth in height should be controlled regularly. Therapy with dexamethasone tablets should be of limited duration or it should be carried out alternatingly (e.g. every other day, but then double dose).
Dexamethasone should not be used routinely in preterm neonates with respiratory problems.
In elderly patients, a special risk-benefit analysis should be carried out because of the increased risk of osteoporosis.
The use of dexamethasone can lead to positive results in doping controls.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription.
What other medicines influence the effect of dexamethasone?
How does dexamethasone influence the effect of other medicines?
Glucocorticoids can suppress skin reactions to allergy tests.
If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.
Pregnancy
Dexamethasone crosses the placenta. During pregnancy, especially in the first three months, medicine should only be used after a careful risk-benefit assessment. Therefore, women should inform the doctor if they are already pregnant or if they become pregnant. During long-term treatment with glucocorticoids during pregnancy, growth disorders in the unborn child cannot be excluded. If glucocorticoids are administered towards the end of pregnancy, there is a risk of underactive adrenal cortex in the newborn, which may necessitate replacement therapy that has to be slowly reduced.
Breast-feeding
Glucocorticoids, including dexamethasone, are excreted into breast milk. Harm to infants is not yet known. Nevertheless, the need for treatment during lactation should be closely examined. If the disease requires higher doses, breast-feeding should be discontinued. Please contact your doctor immediately.
To date there is no evidence that dexamethasone tablets affect the ability to drive or operate machinery, or work without safe foothold. However, do not drive, use any tools or machines or carry out any hazardous tasks if you experience side effects, such as confusion, hallucinations, dizziness, tiredness, sleepiness, fainting or blurred vision.
If you have been told by your doctor that you have an intolerance to some sugars, contact your doctor before taking this medicinal product.
This medicine contains less than 1 mmol sodium (23 mg) per tablet, that is to say essentially ‘sodium-free’.
Always take this medicine exactly as your doctor has told you. Your doctor will determine the dose for you individually. Please follow the instructions in order for dexamethasone tablets to have the proper effect. Check with your doctor or your pharmacist if you are not sure.
Unless otherwise prescribed by your doctor, the usual doses for the following conditions are:
Tablets for oral use.
Take the tablets during or after a meal; swallowed whole, with a sufficient amount of liquid. If possible, the daily dose should be taken as a single dose in the morning. In diseases that require a high-dose therapy, multiple daily dosing is often required to achieve maximum effect.
The duration of treatment depends on the underlying disease and the course of the disease. Your doctor will specify a treatment regimen, which you should strictly follow. Once a satisfactory treatment result is achieved, the dose will be reduced to a maintenance dose or the treatment terminated. In principle, the dose should be reduced gradually.
In underactive thyroid or liver cirrhosis, low doses may be sufficient or a dose reduction may be necessary.
Even if taken for a short time in large quantities, dexamethasone is generally tolerated without complications. There are no special measures required. If you notice increased or unusual side effects, you should talk to your doctor.
A missed dose may be taken on the same day and the next day the dose prescribed by your doctor should be taken as usual.
Do not take a double dose to make up for the forgotten dose.
If you forget to take several doses, this can lead to a recurrence or worsening of the disease being treated. In such cases, you should talk to your doctor who will review the treatment and adjust it, if needed.
Always follow the dosing schedule prescribed by the doctor. Dexamethasone tablets must never be discontinued without discussion with your doctor, particularly since long-term treatment can lead to a decrease in the body’s production of glucocorticoids (underactive adrenal cortex). This is a highly physically stressful situation without adequate glucocorticoid production and can be fatal.
If you have any further questions on the use of this medicine, ask your doctor or pharmacist.
Like all medicines, this medicine can cause side effects, although not everybody gets them.
In hormone replacement therapy, the risk of side effects is low with the use of recommended doses. With prolonged use, especially of high doses, however, side effects of varying degrees can be expected regularly, but their frequency cannot be clearly specified.
