dexamethasone injection uses MedlinePlus FDA label

Dexamethasone injection is a corticosteroid medicine. It reduces inflammation and suppresses an excessive immune response. Doctors use it when rapid treatment is needed or when oral medicine cannot be taken.
Common uses include:
  • Severe allergic reactions and swelling, alongside other urgent treatment when needed
  • Acute asthma/COPD flare-ups and airway inflammation
  • Inflammatory or autoimmune diseases, such as severe arthritis, lupus, skin, bowel, kidney, or blood disorders
  • Brain swelling caused by a brain tumor, injury, or certain infections
  • Certain cancers, including as part of treatment for leukemia, lymphoma, or multiple myeloma
  • Prevention or treatment of chemotherapy-related nausea and vomiting
  • After surgery, to reduce nausea and vomiting
  • Severe COVID-19, mainly in patients who need supplemental oxygen or ventilatory support, under medical supervision
  • Adrenal insufficiency in selected situations where steroid replacement is required
Possible short-term effects include high blood sugar, stomach upset, mood or sleep changes, increased appetite, and raised blood pressure. It can also mask or worsen infections. Repeated or prolonged courses can cause more serious steroid effects, so it should be given only in the prescribed dose and route.
Do not self-inject or stop a prolonged course suddenly without medical advice. The MedlinePlus dexamethasone information lists inflammatory, allergic, respiratory, and cancer-related indications and key safety precautions.

Cardarone (amiodarone) injection is an intravenous antiarrhythmic medicine used in a hospital or emergency setting to treat dangerous fast heart rhythms.
Main uses
  • Ventricular fibrillation (VF), especially recurrent or resistant VF
  • Hemodynamically unstable ventricular tachycardia (VT), meaning VT causing low blood pressure, chest pain, shock, or reduced consciousness
  • Acute control or prevention of recurrent VT/VF when oral amiodarone cannot be taken, followed by oral treatment when appropriate
  • In cardiac arrest protocols, it may be used for shock-refractory VF or pulseless VT under trained resuscitation care
The official IV product indication is treatment and prevention of recurrent VF and unstable VT that has not responded to other treatment, as described in the amiodarone injection prescribing information.
Important cautions
  • It must be given with continuous ECG and blood-pressure monitoring.
  • It can cause low blood pressure, slow pulse, AV block, worsening arrhythmias, and liver injury.
  • It is generally avoided in cardiogenic shock, marked bradycardia, or second/third-degree heart block without a pacemaker.
  • It has important drug interactions, including with some anticoagulants and medicines that prolong the QT interval.
  • It is not a self-injection medicine and is not appropriate for ordinary palpitations without medical assessment.
