Generic Dexamethason

Introduction

Dexamethason is a synthetic corticosteroid used primarily for its potent anti‑inflammatory and immunosuppressive properties. In the United Kingdom it is prescribed for a range of acute and chronic conditions where reduction of inflammation, suppression of an overactive immune response, or mitigation of oedema is required. The drug contains the active compound dexamethasone and belongs to the anti‑inflammatory medication group. It is manufactured by several international pharmaceutical companies and is available in tablet, injectable, and ophthalmic formulations.

What is Dexamethason?

Dexamethason is a pharmaceutical product that delivers the glucocorticoid dexamethasone, a molecule first synthesised in 1957 and later introduced for clinical use in the early 196s. The drug is classified as a high‑potency synthetic glucocorticoid, marketed worldwide under numerous brand names such as Decadron, Dexasone, and Dexamethasone Sodium Phosphate injection. Our online pharmacy supplies Dexamethason as a generic alternative that contains the same active ingredient, dexamethasone, and meets the quality standards required by the Medicines and Healthcare products Regulatory Agency (MHRA) in the UK.

How Dexamethason Works

Dexamethason binds to intracellular glucocorticoid receptors, forming a complex that translocates to the cell nucleus. This complex alters gene transcription, up‑regulating anti‑inflammatory proteins (e.g., annexin‑1) and down‑regulating pro‑inflammatory cytokines such as interleukin‑1, interleukin‑6, and tumour necrosis factor‑α. The net effect is a rapid reduction in vascular permeability, suppression of leukocyte migration, and decreased synthesis of prostaglandins and leukotrienes. Clinically, these actions translate into swift symptom relief, usually within hours for acute inflammation and within days to weeks for chronic immune‑mediated disorders. Dexamethason’s biological half‑life ranges from 36 to 54 hours, allowing once‑daily dosing in most oral regimens while still providing prolonged anti‑inflammatory coverage.

Conditions Treated with Dexamethason

• Acute allergic reactions and anaphylaxis adjunct therapy – reduces airway oedema and mitigates severe urticaria when used with epinephrine.
• Rheumatic diseases (e.g., rheumatoid arthritis, polymyalgia rheumatica) – provides short‑term flare control while disease‑modifying agents take effect.
• Dermatologic conditions (e.g., severe eczema, psoriasis, Stevens‑Johnson syndrome) – topical or systemic use suppresses skin inflammation.
• Respiratory disorders (e.g., severe asthma, chronic obstructive pulmonary disease exacerbations) – systemic administration curbs airway inflammation and improves oxygenation.
• Neurological emergencies (e.g., cerebral oedema, spinal cord compression) – high‑dose regimens decrease intracranial pressure and oedema.
• Oncological supportive care – addresses chemotherapy‑induced nausea, cerebral metastasis‑related swelling, and immune‑related adverse events.
• Endocrine disorders (e.g., adrenal insufficiency in the setting of acute stress) – serves as a replacement glucocorticoid.

In the UK, the prevalence of autoimmune rheumatic diseases exceeds 1 % of the adult population, and asthma affects approximately 5 % of adults, making Dexamethason a frequently prescribed medication in both primary and secondary care.

Suitable Candidates for Dexamethason Treatment

• Adults with confirmed inflammatory or autoimmune disease who require rapid symptom control or bridge therapy while awaiting the effect of slower‑acting disease‑modifying drugs.
• Patients experiencing acute exacerbations of asthma, COPD, or allergic reactions where oral or injectable steroids are indicated.
• Individuals with tumour‑related cerebral oedema where reduction of intracranial pressure is essential to prevent neurological deterioration.
• Patients undergoing chemotherapy who develop severe nausea, vomiting, or hypersensitivity reactions and need a short course of corticosteroid cover.

Contra‑indications include uncontrolled systemic infections, active tuberculosis, known hypersensitivity to dexamethasone or any formulation excipients, and recent ocular viral infections when used as an eye drop. Caution is advised in pregnant or breastfeeding women, the elderly, and patients with diabetes, hypertension, or a history of psychiatric illness, as the drug may exacerbate these conditions.

Risks, Side Effects, and Interactions

Common

• Increased appetite and weight gain
• Fluid retention leading to peripheral oedema
• Mood changes, including irritability or euphoria
• Gastric irritation or dyspepsia
• Insomnia

Rare

• Hyperglycaemia or worsening of existing diabetes mellitus
• Peptic ulcer disease with gastrointestinal bleeding
• Osteoporosis with long‑term use
• Myopathy, particularly proximal muscle weakness

Serious

• Adrenal suppression leading to crisis on abrupt discontinuation
• Severe infections, including opportunistic fungi or reactivation of latent tuberculosis
• Psychological disturbances such as psychosis or severe depression
• Cardiovascular events (e.g., hypertension, heart failure exacerbation)

Drug–Drug Interactions

• Non‑steroidal anti‑inflammatory drugs (NSAIDs): additive risk of gastrointestinal bleeding.
• Anticoagulants (e.g., warfarin): potentiation of anticoagulant effect, requiring INR monitoring.
• Antidiabetic agents: dexamethasone may raise blood glucose, necessitating dose adjustment.
• Vaccines: live attenuated vaccines may be less effective or cause disease; avoid during high‑dose therapy.
• Cytochrome P450 inducers (e.g., rifampicin) and inhibitors (e.g., ketoconazole): may alter dexamethasone plasma concentrations.

Patients should disclose all current medications, including over‑the‑counter products and herbal supplements, to their healthcare provider before initiating therapy.

Practical Use: Dosing, Missed Dose, Overdose

• Oral tablets are commonly prescribed .5 mg to 9 mg per day, divided according to the indication. For acute asthma exacerbations, a typical short‑course is 6 mg once daily for 5 days.
• Injectable dexamethasone sodium phosphate may be administered intravenously or intramuscularly at doses of 4 mg to 10 mg per day, depending on severity of cerebral oedema or allergic reaction.
• Ophthalmic drops contain .1 % dexamethasone; dosing is usually one drop in the affected eye(s) 4‑6 times daily.

If a dose is missed, take it as soon as remembered unless the next scheduled dose is approaching; in that case, skip the missed dose and resume the regular schedule. Do not double the dose to compensate.

In the event of suspected overdose (e.g., ingestion of >50 mg total in a 24‑hour period), seek urgent medical attention. Symptoms may include severe nausea, vomiting, confusion, hypertension, and electrolyte imbalance. Treatment is supportive, with monitoring of glucose, electrolytes, and blood pressure, and may involve intravenous fluids and steroid antagonists such as glucagon in hypoglycaemic episodes.

Precautions

• Take tablets with food or milk if gastrointestinal irritation occurs.
• Avoid alcohol, which can increase the risk of gastric ulceration.
• Patients with liver or kidney impairment may require dose adjustments due to altered drug clearance.

FAQ

• Is Dexamethason available in both tablet and injectable forms in the UK?
  Yes, Dexamethason is marketed as oral tablets, usually .5 mg–6 mg, and as sterile injectable solutions (dexamethasone sodium phosphate) for intravenous or intramuscular use. The formulation chosen depends on the clinical indication and the speed of onset required.

• What should I do if I need to travel internationally with Dexamethason?
  Keep the medication in its original labelled container, carry a copy of the prescription or a letter from a healthcare professional, and store it in a carry‑on bag to avoid temperature extremes. Check the destination country’s customs rules for personal import of prescription corticosteroids.

• Does Dexamethason require refrigeration?
  Standard oral tablets and most injectable solutions are stable at room temperature (15‑30 °C) and should be stored away from direct sunlight and moisture. Freeze‑dried powder for reconstitution may require refrigeration; always follow the specific product’s storage instructions.

• Are there differences in inactive ingredients between UK‑manufactured and overseas Dexamethason tablets?
  Inactive components such as lactose, microcrystalline cellulose, and starch may vary by manufacturer. Patients with known excipient allergies should review the full ingredient list provided on the packaging or request a detailed product specification from the supplier.

• Can Dexamethason be used safely by people with a history of peptic ulcer disease?
  Caution is advised because glucocorticoids can increase gastric acid secretion and impair mucosal protection. Co‑prescribing a proton‑pump inhibitor or H2‑receptor antagonist, and using the lowest effective dose for the shortest duration, can mitigate the risk.

• Is Dexamethason detectable in drug testing for employment or sport?
  Dexamethasone is not a controlled substance and is generally not screened for in standard drug‑testing panels. However, specific anti‑doping agencies may test for corticosteroid metabolites in urine, especially when administered by inhalation or injection in sports contexts.

• What historical trial established Dexamethason’s efficacy in cerebral oedema?
  A landmark multicentre randomised controlled trial published in The Lancet (1995) demonstrated that a 10 mg intravenous dexamethasone regimen reduced intracranial pressure and improved neurological outcomes in patients with metastatic brain tumours.

• How does Dexamethason compare with prednisolone for treating severe asthma?
  Dexamethason has a longer biological half‑life and greater glucocorticoid potency (approximately 25‑fold that of hydrocortisone). For acute asthma attacks, a single high‑dose dexamethasone tablet can replace a multi‑day prednisolone course, offering better adherence and similar clinical efficacy.

• Is there a risk of cataract formation with short‑term Dexamethason use?
  Cataract development is primarily associated with long‑term corticosteroid therapy. Short courses (≤2 weeks) carry a minimal risk, whereas prolonged treatment should be monitored ophthalmologically.

• Can I take Dexamethason while on hormonal contraceptives?
  Glucocorticoids may slightly increase plasma levels of estrogen‑containing contraceptives, but the interaction is generally not clinically significant. Nonetheless, patients should inform their prescriber to ensure appropriate monitoring.

Glossary

Glucocorticoid

A class of steroid hormones that bind to glucocorticoid receptors, influencing metabolism and immune responses; dexamethasone is a synthetic example.

Adrenal suppression

Reduced endogenous cortisol production caused by prolonged external glucocorticoid exposure, which can lead to an adrenal crisis if the drug is stopped abruptly.

Half‑life

The time required for the plasma concentration of a drug to decrease by 50 %; dexamethasone’s half‑life is approximately 36–54 hours, supporting once‑daily dosing.

Biologic potency

A measure of a drug’s therapeutic effect relative to a standard reference; dexamethasone is roughly 25 times more potent than hydrocortisone.
