Halothane — Uses, Dosage, Side Effects & Safety

Drug class: Emergency & Critical Care

Overview

Halothane is a general anesthetic used to induce and maintain anesthesia during surgical procedures. It is administered as a vapor through inhalation and works by depressing the central nervous system, leading to loss of consciousness and sensation so that patients do not feel pain during surgery. Halothane acts quickly and is commonly used for both adults and children, especially in settings where rapid induction and recovery are desired. It is often chosen for pediatric anesthesia due to its non-irritating properties. Key points for patients: Halothane is only given in hospitals or surgical centers by trained professionals. You will be closely monitored during its use. Inform your healthcare provider about any liver problems, allergies, or previous reactions to anesthesia.
