Reboxetine is a medication primarily used to treat major depressive disorder. It belongs to a class of drugs known as norepinephrine reuptake inhibitors (NRIs), which work by increasing the levels of norepinephrine, a neurotransmitter that plays a key role in mood regulation, in the brain. Unlike some other antidepressants, reboxetine is not commonly associated with sedation or weight gain. It is typically prescribed when other treatments have not been effective, and it may take several weeks to notice its full effects. As with any medication, it is important to discuss potential side effects and interactions with a healthcare provider.
