4.2 Posology and method of administration


Dosage depends on the nature and severity of the disease and the individual response of the patient to treatment. In general, relatively high initial doses are administered, and they should be significantly higher in acute severe forms than in chronic diseases.

All doses are expressed as mg dexamethasone base.

Unless otherwise prescribed, the following dosage recommendations apply:

Systemic administration:

- Cerebral oedema:

Adults: depending on the cause and severity, initial dose of 6.6– 8.25 mg (up to 66 mg) i.v., followed by 13.2– 19.8 mg (up to 39.6 mg)/day i.v., divided into 3– 4 (6) individual doses for 4– 8 days. A longer-term, lower-dose administration of Dexamethasone Krka may be required during irradiation and in the conservative treatment of inoperable brain tumours.

- Cerebral oedema due to bacterial meningitis: 0.12 mg/kg body weight every 6 hours for 4 days, children 0.33 mg/kg body weight every 12 hours for 2 days; starting before the first administration of the antibiotic. Severe cases, toxic states (e.g. tuberculosis, typhoid; only with concomitant anti infective therapy): 3.3– 16.5 mg/day i.v., in single cases (e.g. typhoid) initially up to 165 mg. Consideration should be given to official guidance for the resort to corticotherapy for the adequate management of infectious diseases.

- Post-traumatic shock/prophylaxis of post-traumatic shock-lung syndrome: initially 33-82.5 mg (children 33 mg) i.v., a repeated dose after 12 hours or 13.2– 33 mg every 6 hours for 2– 3 days.

- Severe acute asthma attack: Adults: 6.6– 16.5 mg i.v. as early as possible. Children: 0.12– 0.25 mg/kg body weight i.v. Doses should be repeated if necessary, based on the individual response and clinical need.

- Acute skin diseases: Depending on the nature and extent of the disease, daily doses of 6.6– 33 mg i.v., in severe cases up to 82.5 mg. Followed by treatment with decreasing doses.

- Active phases of rheumatic systemic diseases: systemic lupus erythematosus 4.95– 13.2 mg/day.

- Active rheumatoid arthritis with a severe, progressive course: in rapidly destructive forms 9.9– 13.2 mg/day, in extra-articular manifestations 4.95– 9.9 mg/day.

- Palliative treatment of malignant tumours: initially 6.6– 13.2 mg/day, in prolonged treatment 3.3– 9.9 mg/day.

- Prophylaxis and treatment of cytostatic-induced vomiting in anti-emetic regimens: 6.6– 16.5 mg i.v. before starting chemotherapy, then 3.3– 6.6 mg one to two times daily for 2– 3 days as necessary (moderately emetogenic chemotherapy), or up to 3-4 days (highly emetogenic chemotherapy).

- Prophylaxis and treatment of post-operative vomiting: a single dose of 3.3– 6.6 mg i.v. before the start of surgery; in children over 2 years of age: 0.12 mg/kg body weight (max. up to 4.13 mg).

- Treatment of Covid-19: Adult patients 6 mg i.v., once a day for up to 10 days. Paediatric population: Paediatric patients (adolescents aged 12 years and older) are recommended to take 6 mg/dose i.v. once a day for up to 10 days. Duration of treatment should be guided by clinical response and individual patient requirements.

Elderly, renal impairment, hepatic impairment: No dose adjustment is needed.

Local administration:

Local infiltration and injection therapy is usually carried out with 3.3– 6.6 mg;

1.65 mg of dexamethasone is sufficient if injected into small joints or administered by subconjunctival injection.

Method of administration

Dexamethasone Krka should be administered by slow (over 2-3 minutes) intravenous injection, or by infusion, but may also be administered intramuscularly if problems occur with venous access and blood circulation is adequate. Dexamethasone Krka may also be administered by infiltration and by intra-articular or subconjunctival injection. Treatment duration depends on the indication.

In hypothyroidism or liver cirrhosis, low doses may be sufficient or a dose reduction may be necessary.

Administration by intra-articular injection should be considered open joint procedure and carried out under strict aseptic conditions. A single intra-articular injection is usually sufficient for effective symptom relief. Should a repeated injection be necessary, it should not be administered sooner than after 3– 4 weeks. Not more than 3– 4 injections should be used on one joint. A medical check of the joint is required, especially after repeated injections.

Infiltration: The region of greatest pain or tendon attachments is infiltrated with Dexamethasone Krka. Caution, do not inject into tendon! Frequent injections should be avoided and strict aseptic precautions should be observed.

In case high doses are required in a single treatment, use of dexamethasone medicinal products with higher strengths/volume should be considered.

Suitability for use

Only clear solutions should be used. The content of the ampoule is intended for single withdrawal. Any remaining solution for injection should be disposed.

See section 6.6 for compatibility information.

4.3 Contraindications

Hypersensitivity to the active substances or to any of the excipients listed in section 6.1.

Systemic fungal infection; systemic infection unless specific anti-infective therapy is employed.

Intra-articular injection is contraindicated

- if infection is present in or in the immediate vicinity of the joint to be treated

- in bacterial arthritis

- instability of the joint to be treated

- in tendency to bleeding (spontaneously or due to anticoagulant agents)

- in periarticular calcification

- in avascular bone necrosis

- in tendon rupture

- in Charcot joint

Infiltration without causal additional treatment is contraindicated if infection is present in the administration area, as is subconjunctival administration in viral, bacterial and mycotic eye conditions or corneal injuries and ulcers.

4.4 Special warnings and precautions for use

Single cases of severe anaphylactic reactions with circulatory collapse, cardiac arrest, arrhythmia, bronchospasm and/or hypotension or hypertension have been observed with the use of Dexamethasone Krka.

Through immunosuppression, treatment with Dexamethasone Krka can lead to an increased risk for bacterial, viral, parasitic, opportunistic and fungal infections. It can mask the symptoms of an existing or developing infection, thereby making a diagnosis more difficult. Latent infections, like tuberculosis or hepatitis B, can be reactivated.

In cases of particular physical stress situations (trauma, surgery, childbirth, etc.) during treatment with Dexamethasone Krka, a temporary increase in dose may be required.

Treatment with Dexamethasone Krka should only be administered in the event of the strictest indications and, if necessary, additional targeted anti-infective treatment if any of the following is present:

- acute viral infections (hepatitis B, herpes zoster, herpes simplex, varicella, herpetic keratitis)

- HBsAG-positive chronic active hepatitis

- approximately 8 weeks prior to 2 weeks after vaccinations with live vaccines

- systemic mycoses and parasitoses (e.g. nematodes)

- in patients with suspected or confirmed strongyloidiasis (infection with threadworms), glucocorticoids can lead to activation and mass proliferation of these parasites

- poliomyelitis

- lymphadenitis after BCG vaccination - acute and chronic bacterial infections

- in patients with a history of tuberculosis, use only under tuberculostatic protection

In addition, treatment with Dexamethasone Krka should only be administered in strict indications and, if necessary, additional specific treatment must be provided for:

- gastrointestinal ulcers

- osteoporosis

- severe cardiac insufficiency

- high blood pressure that is difficult to control

- diabetes mellitus that is difficult to control

- psychiatric disorders (also in the past), including suicidality: neurological or psychiatric monitoring is recommended

- narrow- and wide-angle glaucoma: ophthalmic monitoring and adjunctive therapy are recommended

- corneal ulcerations and corneal injuries: ophthalmic monitoring and adjunctive therapy are recommended

Visual disturbance

Visual disturbances may be reported with systemic and topical corticosteroid use. If a patient presents with symptoms such as blurred vison or other visual disturbances, the patient should be considered for referral to an ophthalmologist for evaluation of possible causes which may include cataract, glaucoma or rare diseases such as central serous chorioretinopathy (CSCR) which have been reported after use of systemic and topical corticosteroids.

Because of the risk of an intestinal perforation, Dexamethasone Krka may only be used under urgent indication and under appropriate monitoring for:

- severe ulcerative colitis with threatened perforation, possibly without peritoneal irritation

- diverticulitis

- enteroanastomosis (immediately post-operatively)

Signs of peritoneal irritation after gastrointestinal perforation may be absent in patients receiving high doses of glucocorticoids.

The possibility of a higher need for insulin or oral antidiabetics must be taken into consideration when administering Dexamethasone Krka to diabetics.

Regular blood pressure monitoring is necessary during treatment with Dexamethasone Krka, particularly during administration of higher doses and in patients with high blood pressure that is difficult to control.

Because of the risk of deterioration, patients with severe cardiac insufficiency should be carefully monitored.

With high doses of dexamethasone bradycardia may occur.

Severe anaphylactic reactions may occur.

The risk of tendon disorders, tendinitis and tendon rupture is increased when fluoroquinolones and glucocorticoids are administered together.

A concurrent myasthenia gravis may initially worsen during treatment with Dexamethasone Krka.

Vaccinations with inactivated vaccines are generally possible. However, it should be noted that the immune response and thus the vaccine may be compromised at higher doses of corticosteroids.

At high doses, sufficient potassium intake and sodium restriction should be ensured and serum potassium levels should be monitored.

Abrupt discontinuation of treatment after about 10 days can result in exacerbation or relapse of the underlying disease and acute adrenocortical insufficiency/cortisone withdrawal syndrome; therefore, the dose should be slowly reduced if treatment is to be discontinued.

Certain viral diseases (chickenpox, measles) may be very severe in patients treated with glucocorticoids. Immunocompromised patients without previous chickenpox or measles infection are particularly at risk. If these patients have contact with people infected with measles or chickenpox while undergoing treatment with Dexamethasone Krka, a preventative treatment should be introduced, if necessary.

In COVID-19 patients, systemic corticosteroids should not be stopped for patients who are already treated with systemic (oral) corticosteroids for other reasons (e.g. patients with chronic obstructive pulmonary disease) but not requiring supplemental oxygen.

In post marketing experience tumour lysis syndrome (TLS) has been reported in patients with haematological malignancies following the use of dexamethasone alone or in combination with other chemotherapeutic agents. Patient at high risk of TLS, such as patients with high proliferative rate, high tumour burden, and high sensitivity to cytotoxic agents, should be monitored closely and appropriate precaution taken.

Intravenous administration should be by slow (over 2– 3 minutes) injection, since side effects such as unpleasant prickling or paraesthesia can occur if injected too rapidly.

Dexamethasone Krka is intended for short-term use. If used improperly over a longer period, additional warnings and precautions, as described for long-term administration of glucocorticoid-containing medicinal products, should be considered.

Possible systemic side effects and interactions should be taken into account after local administration.

Intra-articular administration of glucocorticoids increases the risk of joint infections. Longterm administration and repeated injections of glucocorticoids into weight-bearing joints can aggravate wear-related changes of the joints. This is probably due to overburdening of the affected joints after pain or other symptoms have been relieved.

Pheochromocytoma crisis

Pheochromocytoma crisis, which can be fatal, has been reported after administration of systemic corticosteroids. Corticosteroids should only be administered to patients with suspected or identified pheochromocytoma after an appropriate risk/benefit evaluation.

Hypertrophic cardiomyopathy

Hypertrophic cardiomyopathy was reported after systemic administration of corticosteroids including dexamethasone to prematurely born infants. In the majority of cases reported, this was reversible on withdrawal of treatment. In preterm infants treated with systemic dexamethasone diagnostic evaluation and monitoring of cardiac function and structure should be performed (section 4.8).

Local ophthalmic use:

Cushing's syndrome and/or adrenal suppression can occur after systemic absorption of ophthalmic dexamethasone during intensive or long-term treatment in predisposed patients, including children and patients treated with CYP3A4 inhibitors (including ritonavir and cobicistat). In these cases, the treatment should be gradually discontinued.

Caution is advised with subconjunctival administration of steroids as this may be associated with a potential risk of scleral thinning or scleral melt.

Children and adolescents

Preterm neonates:

Available evidence suggests long-term neurodevelopmental adverse events after early treatment (< 96 hours after birth) of premature infants with chronic lung disease at starting doses of 0.21mg/kg twice daily.

In the growth phase of children, the benefit-risk balance of treatment with Dexamethasone Krka should be carefully weighed.

Elderly patients

Because elderly patients are at an increased risk of osteoporosis, the benefit-risk balance of treatment with Dexamethasone Krka should be carefully weighed.

The use of Dexamethasone Krka can lead to positive results in doping controls.

Important information about some of the ingredients

This medicinal product contains 3 mg sodium per ampoule, equivalent to 0.15% of the WHO recommended maximum daily intake of 2 g sodium for an adult.

4.5 Interaction with other medicinal products and other forms of interaction

Oestrogens (e.g. oral contraceptives): The half-life of glucocorticoids may be prolonged. Therefore, the effect of corticoids may be increased.

Medicines that induce CYP3A4, such as rifampicin, phenytoin, carbamazepine, barbiturates and primidone: The effect of corticoids may be reduced.

CYP3A4 inhibitors (including ketoconazole, itraconazole, ritonavir and cobicistat) can reduce dexamethasone clearance, which can lead to an increase in effect and adrenal suppression/Cushing's syndrome. This combination should be avoided, except in cases where the benefit of treatment outweighs the increased risk for systemic adverse effects of corticosteroids. If this is the case, the patients should be monitored for systemic corticosteroid effects.

Ephedrine: The metabolism of glucocorticoids may be accelerated and thus their effectiveness reduced.

ACE inhibitors: Increased risk of blood count changes.

Cardiac glycosides: The effect of glycosides may be increased by potassium deficiency.

Saluretics/laxatives: Potassium excretion may be increased.

Antidiabetics: The hypoglycaemic effect may be reduced.

Coumarin derivatives: The anticoagulant effect may be reduced or increased. Dosage adjustment of the anticoagulant may be necessary when co-administered.

Nonsteroidal anti-inflammatory drugs (NSAIDs), salicylates and indomethacin: The risk of gastrointestinal ulcers and bleeding is increased.

Non-depolarizing muscle relaxants: The muscle-relaxing effect may last longer.

Atropine, other anticholinergics: Additional intraocular pressure increases are possible during concomitant use.

Praziquantel: Corticosteroids may cause a fall in praziquantel concentration in the blood.

Chloroquine, hydroxychloroquine, mefloquine: There is an increased risk of myopathies, cardiomyopathies.

Protirelin: Reduced increase in TSH may be noted during administration of protirelin.

Immunosuppressive agents: Increased susceptibility to infections and possible aggravation or manifestation of latent infections. Additionally, for cyclosporine: The blood levels of cyclosporine are increased: There is an increased risk of seizures.

Fluoroquinolones may increase the risk of tendon disorders.

Effect on investigation methods:

Skin reactions in allergy tests can be suppressed.

4.6 Fertility, pregnancy and lactation


Dexamethasone crosses the placenta. During pregnancy, especially in the first trimester, this medicine should only be administered after careful benefit-risk assessment.

In long-term treatment with glucocorticoids during pregnancy, foetal growth disorders cannot be excluded.

Administration of corticosteroids to pregnant animals can cause abnormalities of foetal development, including cleft palate, intra-uterine growth retardation and effects on brain growth and development. There is no evidence that corticosteroids result in an increased incidence of congenital abnormalities, such as cleft palate/lip in humans (see section 5.3).

If glucocorticoids are administered towards the end of pregnancy, there is a risk of atrophy of the foetal adrenal cortex, which may necessitate replacement therapy in the newborn, which has to be slowly reduced.

Studies have shown an increased risk of neonatal hypoglycaemia following antenatal administration of a short course of corticosteroids including dexamethasone to women at risk for late preterm delivery.


Dexamethasone is excreted in breast milk. There have been no known cases of harm to the infant. Nevertheless, the medicine should be used under strict indications during lactation. If the disease requires higher doses, breast-feeding should be discontinued.

4.7 Effects on ability to drive and use machines

There have been no indications that Dexamethasone Krka affects the ability participate actively in road traffic or use machines; the same applies to working without a secure hold.

4.8 Undesirable effects

The risk of undesirable effects is low during short-term treatment with dexamethasone, with the exception of parenteral high-dose therapy where changes in electrolytes, occurrence of oedema, possibly increase in blood pressure, heart arrest, heart rhythm disturbances or convulsions can occur, and clinical manifestations of infections can also be observed during short-term treatment. Attention should be paid to possible gastric and intestinal ulcerations (often stress-induced), because corticoid treatment can reduce their symptoms, and to decrease in glucose tolerance.

The following undesirable effects may occur; they are highly dependent on the dose and duration of treatment, so their frequency cannot be specified:

Infections and infestations:

Masking of infections, manifestation and exacerbation of viral infections, fungal infections, bacterial, parasitic and opportunistic infections, activation of strongyloidiasis (see section 4.4).

Blood and lymphatic system disorders:

Moderate leucocytosis, lymphocytopenia, eosinopenia, polycythaemia.

Immune system disorders:

Reproductive system and breast disorders:

Disorders of sexual hormone secretion (consequently: irregular menstruation up to amenorrhea, hirsutism, impotence).

General disorders and administration site conditions:

Delayed wound healing.

Local administration: Local irritation and intolerability reactions are possible (sensation of heat, prolonged pain), particularly with ophthalmic use. Skin atrophy and atrophy of subcutaneous tissue at injection site cannot be excluded if corticoids are not carefully injected into the joint cavity.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via Yellow Card Scheme, Website: or search for MHRA Yellow Card in the Google Play or Apple App Store.

4.9 Overdose


Acute intoxications with dexamethasone are not known. In case of chronic overdosing, an increase in undesirable effects (see section 4.8), in particular endocrine, metabolic and electrolyte-related effects, can be expected.

5. Pharmacological properties
5.1 Pharmacodynamic properties

Pharmacotherapeutic group: Corticosteroids for systemic use, glucocorticoids, ATC code: H02AB02.

Dexamethasone is a mono-fluorinated glucocorticoid with pronounced anti-allergic, anti-inflammatory and membrane-stabilising properties and effects on carbohydrate, protein and fat metabolism.

Dexamethasone has an approximately 7.5 times greater glucocorticoid effect than prednisolone and prednisone, and compared to hydrocortisone it is 30 times more effective, lacking mineralocorticoid effects.

Glucocorticoids, such as dexamethasone, exert their biological effects by activating the transcription of corticosteroid-sensitive genes. The anti-inflammatory, immunosuppressive and anti-proliferative effects are caused by decreased formation, release and activity of inflammatory mediators, by the inhibition of specific functions and the migration of inflammatory cells. In addition, the effect of sensitised T lymphocytes and macrophages on target cells may be prevented by corticosteroids.

When long-term corticoid treatment is required, the possibility of induction of transient adrenal insufficiency must be considered. The suppression of the hypothalamic-pituitary-adrenal axis also depends on individual factors.

The RECOVERY trial (Randomised Evaluation of COVid-19 thERapY,)1 is an investigator-initiated, individually randomised, controlled, open-label, adaptive platform trial to evaluate the effects of potential treatments in patients hospitalised with COVID-19.

The trial was conducted at 176 hospital organizations in the United Kingdom. There were 6425 Patients randomised to receive either dexamethasone (2104 patients) or usual care alone (4321 patients). 89% of the patients had laboratory-confirmed SARS-CoV-2 infection.

At randomization, 16% of patients were receiving invasive mechanical ventilation or extracorporeal membrane oxygenation, 60% were receiving oxygen only (with or without non invasive ventilation), and 24% were receiving neither.

The mean age of patients was 66.1+/-15.7 years. 36% of the patients were female. 24% of patients had a history of diabetes, 27% of heart disease and 21% of chronic lung disease.

Primary endpoint

Mortality at 28 days was significantly lower in the dexamethasone group than in the usual care group, with deaths reported in 482 of 2104 patients (22.9%) and in 1110 of 4321 patients (25.7%), respectively (rate ratio, 0.83; 95% confidence interval [CI], 0.75 to 0.93; P<0.001).

In the dexamethasone group, the incidence of death was lower than that in the usual care group among patients receiving invasive mechanical ventilation (29.3% vs. 41.4%; rate ratio, 0.64; 95% CI, 0.51 to 0.81) and in those receiving supplementary oxygen without invasive mechanical ventilation (23.3% vs. 26.2%; rate ratio, 0.82; 95% CI, 0.72 to 0.94).

There was no clear effect of dexamethasone among patients who were not receiving any respiratory support at randomization (17.8% vs. 14.0%; rate ratio, 1.19; 95% CI, 0.91 to 1.55).

Secondary endpoints

Patients in the dexamethasone group had a shorter duration of hospitalization than those in the usual care group (median, 12 days vs. 13 days) and a greater probability of discharge alive within 28 days (rate ratio, 1.10; 95% CI, 1.03 to 1.17). In line with the primary endpoint the greatest effect regarding discharge within 28 days was seen among patients who were receiving invasive mechanical ventilation at randomization (rate ratio 1.48; 95% CI 1.16, 1.90), followed by oxygen only (rate ratio, 1.15 ;95% CI 1.06-1.24) with no beneficial effect in patients not receiving oxygen (rate ratio, 0.96 ; 95% CI 0.85-1.08).



There were four serious adverse events (SAEs) related to study treatment: two SAEs of hyperglycaemia, one SAE of steroid-induced psychosis and one SAE of an upper gastrointestinal bleed. All events resolved.

5.2 Pharmacokinetic properties

Dexamethasone binds dose-dependently to plasma albumins. At very high doses, the largest portion circulates freely in the blood. In hypoalbuminaemia the proportion of the unbound (active) corticoid rises. Four hours after intravenous administration of radioactively marked dexamethasone in humans, maximum concentration of dexamethasone in the liquor is about 1/6 of its plasma concentration.

With its biological half-life of more than 36 hours, dexamethasone belongs to glucocorticoids with a very long action. Due to its long duration of action, accumulation and overdosing may occur with daily, continuous administration of dexamethasone.

The mean serum elimination half-life of dexamethasone in adults is approximately 250 minutes (+ 80 minutes). It is excreted predominantly through the kidney in form of free dexamethasone alcohol. It is partially metabolised. The metabolites are, as glucoronates or sulphate, also predominantly excreted through the kidneys. Renal dysfunction does not substantially affect the elimination of dexamethasone. The elimination half-life is prolonged in severe liver disease.

5.3 Preclinical safety data

In animal studies, cleft palate was observed in rats, mice, hamsters, rabbits, dogs and primates; not in horses and sheep. In some cases these divergences were combined with defects of the central nervous system and of the heart. In primates, effects in the brain were seen after exposure. Moreover, intrauterine growth can be delayed. All these effects were seen at high dosages.
