Citalopram, also known as Celexa, is a prescription medication used to treat depression. It is not typically considered addictive in the same way that drugs of abuse, such as opioids or stimulants, are. However, it is possible to become dependent on citalopram, and abruptly stopping the medication can lead to withdrawal symptoms. Therefore, it is important to follow your doctor’s instructions when taking citalopram and not to stop or change your dosage without first consulting with your healthcare provider.
