Dexamethasone Dosage

Dexamethasone Injection Dosing Guidelines

Dexamethasone may be given via intravenous (IV) or intramuscular (IM) administration when used to treat potentially serious conditions, such as cerebral edema (swelling of the brain) or shock. The usual IV or IM dose of this drug is 0.4 mg to 10 mg, but may be significantly higher in some cases.
 
Often, the IV or IM dosage is changed to an oral dosage as soon as symptoms have reduced, and the oral dosage is slowly reduced until the medication can be stopped.
 
Dexamethasone may be injected directly into affected joints, tendons, or other areas when used to treat arthritis or when symptoms of a treated condition are localized to one area. The usual dexamethasone dosage for these types of injections is 0.4 mg to 4 mg, depending on the size of the joint and site of the injection.
 

Dexamethasone Ophthalmic (Eye) and Otic (Ear) Dosing Guidelines

The usual initial dose for dexamethasone ophthalmic solution is one or two drops in the affected eye(s) four to six times a day for mild eye conditions and one to two drops every hour for severe conditions. This amount will then be gradually decreased, and eventually stopped, as the condition improves. In most cases, treatment will be no longer than a few weeks in duration.
 
The standard dosage of dexamethasone ophthalmic suspension (Maxidex®) for mild eye conditions is one or two drops in the affected eye(s) four to six times a day. For severe eye conditions, the standard dose is one or two drops in the affected eye(s) every hour. This amount will then be gradually reduced as the condition improves and swelling decreases.
 
The usual initial dose for dexamethasone ear solution is three or four drops in the affected ear(s) two to three times a day. The dose will then be gradually decreased, and eventually stopped, as the condition improves. In most cases, treatment will be no longer than a few weeks in duration.
 
The standard dosage of dexamethasone intravitreal implant (Ozurdex®) is one 0.7-mg intravitreal implant inserted into the affected eye(s). The injection is given by a trained healthcare provider.
