Yes it is. However when it comes to clinical depression you have to understand what you dealing with and that is the damn hardest thing.

There I explained a wave concept now when you stable and begin to taper down you dont have that "safety barrier" that the SSRI will provide and the patient will relapse badly. Usually the dose can be restarted but they generally increase it over time because of tolerance.
In the case of citalopram we push the dose as high as 60mg per day thereafter adding secondary and tertiary agents to maintain the mental state (these are asylum patients so their treatments were very extreme). See no drug works indefinitely. The channels close, cell uptake changes or the receptors recede and so forth so you have to force a response by increasing the concentration of drug i.e the dose. This holds for pain meds, antidepressants, asthma meds, diuretics, diabetic meds hypertensives and so forth.
You cant abruptly stop any antidepressant and if you decide to go of a substance it must be done with authorization of your treating doctor. Now there are times where you will abruptly stop but this is not one of them you can cause some serious issues abruptly stopping an antidepressant
