How It Works

  • Inflammatory disorders can sometimes be treated with dexamethasone. Dexamethasone soothes an overactive immune system and aids in the reduction of inflammation.
  • Dexamethasone mimics the action of cortisol, a hormone secreted by the adrenal glands, which are situated above the kidneys and regulate stress and metabolism.
  • Dexamethasone is a member of the corticosteroid drug subclass. It is a glucocorticoid in particular.

Benefits of Dexamethasone would be the following thing to know about Dexamethasone. The National Institutes of Health (NIH) in the US and the National Health Service in the UK both advise dexamethasone for COVID-19 patients who require mechanical breathing or additional oxygen (without ventilation). For individuals with severe COVID-19, which is defined as having a SpO2 of less than 94% on room air, as well as those who require additional oxygen, mechanical ventilation, or extracorporeal membrane oxygenation, the Infectious Diseases Society of America (IDSA) guideline panel recommends the use of glucocorticoids (ECMO). The IDSA advises against using glucocorticoids in COVID-19 patients who do not have hypoxemia and do not require additional oxygen.

  • May be used to reduce inflammation brought on by a variety of illnesses, including rheumatoid arthritis, multiple sclerosis, ulcerative colitis, endocrine disorders, blood disorders, nerve disorders, eye diseases, kidney diseases, respiratory illnesses, and palliative care.
  • Dexamethasone is often only given for short-term use, however in some circumstances, it may be administered for longer times.
  • Prednisolone and dexamethasone have comparable actions, but dexamethasone has stronger anti-inflammatory, hormonal, and metabolic effects.
  • Dexamethasone is less likely than hydrocortisone to result in fluid retention when administered at the same dosage.
  • There is dexamethasone in generic form.

You are more likely to have the following side effects if you are between the ages of 18 and 60, do not take any other medications, or have any other medical conditions:

  • The most frequent adverse effects are mood changes like agitation, anxiety, and irritability, impaired vision, a change in heart rate, swelling of the limbs (edema or salt and water retention), increased appetite and weight gain, and trouble concentrating.
  • In addition, it’s possible to experience indigestion, facial hair development (particularly in women), high blood pressure, sluggish skin healing, skin thinning, osteoporosis (brittle bones), low potassium levels, and issues controlling blood sugar. Rarely have reports of severe allergic responses been made.
  • Should not be utilized in patients with viral or systemic fungal diseases. Dexamethasone’s anti-inflammatory properties might conceal infection-related symptoms, which may also increase the risk of infection.
  • Some medical disorders, such as heart failure, diabetes, osteoporosis, tuberculosis, cushingoid syndrome, and peptic ulcers, may make a person ineligible.
  • Overdosage may result in fluid retention, potassium loss, salt retention, and weight gain.
  • Should not discontinue using dexamethasone abruptly if it has been used for a long time. To give the adrenal glands time to resume their regular production patterns, gradually reduce the dosage over a period of weeks or months. A dexamethasone withdrawal that is too quick might result in symptoms like nausea, vomiting, exhaustion, bone and muscle pain, and weight loss.
  • To help prevent stomach ulcers while taking dexamethasone, alcohol use should be restricted or avoided.
  • After dexamethasone therapy has ended, it is necessary to wait several months before administering “live vaccinations.”
  • Aspirin, digoxin, NSAIDs, hormonal contraceptives, other medicines metabolized by CYP3A4, and warfarin are only a few of the medications that may interact with each other. Low blood potassium levels brought on by dexamethasone may impair the effectiveness of several cardiac medicines.
  • Use only if the advantages outweigh the hazards when pregnant. When corticosteroids are administered to pregnant mice, rats, and rabbits, animal studies have shown that there is an increased incidence of cleft palate in the offspring. There are no sufficient and reliable research on expectant mothers. When used during pregnancy, corticosteroids should only be taken if the benefits outweigh the risks to the developing baby. Mothers who took high doses of corticosteroids during pregnancy should be closely monitored for any signs of hypoadrenalism in their newborns.

  • If you experience a fever or any other signs of infection while taking dexamethasone, get medical help as soon as you can. Talk to your doctor if you have any worrying side effects or changes in your mood.
  • Put the information that you are taking dexamethasone on a medical alert bracelet.
  • Try to keep away from those who are contagious with a virus like measles or chickenpox. If you believe you may have unintentionally been exposed, get medical help right once.
  • Dexamethasone should not be abruptly stopped when used long-term. To allow the adrenal glands to resume their regular secretion patterns, your doctor will give you instructions on how to gradually lower the dosage of dexamethasone over a period of weeks or months. A dexamethasone withdrawal that is too quick might result in symptoms like nausea, vomiting, exhaustion, bone and muscle pain, and weight loss.
  • After dexamethasone therapy has ended, wait a few months before administering “live vaccinations.”
  • Make sure to let your doctor, dentist, or other medical personnel know that you are taking dexamethasone.

If you take dexamethasone once a day and forget to take it, do so right away. Skip the missed dose and take the next one at the regular time if you don’t realize you missed it until the next day. Unless you have less than two hours until your next dose if you take it twice or three times a day, take the missing dose as soon as you remember.
