Also, potent steroids, such as dexamethasone, have a longer duration of action than less potent steroids, such as hydrocortisone. The route of administration also affects the duration of action, with oral administration having a longer duration of action than intravenous administration.<\/p>\n<h2><strong>Steroid Equivalence<\/strong><\/h2>\n<p>Steroid equivalence refers to the relative potency of different steroids. This is important in determining the correct dose of a steroid, as a higher dose of a less potent steroid may be required to achieve the same effect as a lower dose of a more potent steroid.<\/p>\n<h2><strong>Conversion between Steroids<\/strong><\/h2>\n<p>Conversion between steroids is the process of determining the equivalent dose of one steroid to another. This is important when switching from one steroid to another or when combining steroids with different potencies.<\/p>\n<p><strong><u>A summary of Various Steroid Doses<\/u><\/strong><\/p>\n<p>The following table provides a comprehensive list of various steroids and their equivalent doses.

For example, if a patient has been taking a chronic dose of steroids and there is a shortage or change in availability of the drug formulation, the dose may need to be converted to another form. Similarly, if a patient is receiving a short-term “burst” dose of steroids and there is a change in the drug formulation, the dose may need to be adjusted.<\/p>\n<p>In these cases, the steroid dose conversion calculator can determine the equivalent dose in the new formulation, ensuring that the patient continues receiving the correct amount of steroid to achieve the desired therapeutic effect.<\/p>\n<p>A simple rule to recall the conversion between glucocorticoid formulations<\/p>\n<blockquote>\n<p>Prednisone (5mg) = Hydrocortisone (20mg) = Dexamethasone (0.75mg) = methylprednisolone (4mg)<\/p>\n<\/blockquote>\n<p>It’s important to note that using a steroid dose conversion calculator should always be done under the guidance of a healthcare provider, who can consider the patient’s medical history and other factors that may impact the dose conversion.<\/p>","protected":false},"excerpt":{"rendered":"<p>Steroid Conversion Calculator (Show Both Steroids & Doses) Steroid Conversion Calculator Convert From: Select the Steroid You’re Converting From Betamethasone (IV)Cortisone (PO)Dexamethasone (IV or PO)Hydrocortisone (IV or PO)MethylPrednisoLONE (IV or PO)PrednisoLONE (PO)PredniSONE (PO)Triamcinolone (IV) Drug Dosage in mg Convert To: Select the Steroid You’re Converting To Betamethasone (IV)Cortisone (PO)Dexamethasone (IV or PO)Hydrocortisone (IV or PO)MethylPrednisoLONE […]<\/p>\n","protected":false},"author":1,"featured_media":4411539,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[100],"tags":[],"class_list":["post-4411502","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-endocalculator","post-wrapper","thrv_wrapper"],"_links":{"self":[{"href":"https:\/\/myendoconsult.com\/learn\/wp-json\/wp\/v2\/posts\/4411502","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/myendoconsult.com\/learn\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/myendoconsult.com\/learn\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/myendoconsult.com\/learn\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/myendoconsult.com\/learn\/wp-json\/wp\/v2\/comments?post=4411502"}],"version-history":[{"count":78,"href":"https:\/\/myendoconsult.com\/learn\/wp-json\/wp\/v2\/posts\/4411502\/revisions"}],"predecessor-version":[{"id":4421754,"href":"https:\/\/myendoconsult.com\/learn\/wp-json\/wp\/v2\/posts\/4411502\/revisions\/4421754"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/myendoconsult.com\/learn\/wp-json\/wp\/v2\/media\/4411539"}],"wp:attachment":[{"href":"https:\/\/myendoconsult.com\/learn\/wp-json\/wp\/v2\/media?parent=4411502"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/myendoconsult.com\/learn\/wp-json\/wp\/v2\/categories?post=4411502"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/myendoconsult.com\/learn\/wp-json\/wp\/v2\/tags?post=4411502"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
