Esketamine is a medicine that is prescribed for treatment resistant depression, in combination with an antidepressant.
Esketamine is delivered as a nasal spray that must be self-administered in a clinical setting under the supervision of a healthcare provider.
Esketamine has been found to provide a rapid acting antidepressant response. This means you can start to experience relief of your symptoms within hours. The idea is to use esketamine like training wheels for your antidepressant - it will help you get relief while giving your antidepressant time to work. How long you require treatment depends on your individual response and will be determined by you and your doctor.
