Why is it bad to go off of depression meds suddenly if you feel you may not need them anymore?

Need time to adjust: The vast majority of antidepressants work by increasing neurotransmitters in your brain. As a rule it takes most antidepressants about two weeks to take full effect, and this is why you need to ween off. A sudden stop might throw you back into a derpression.

Makes you sick: Sudden discontinuation of antidepressants can lead to withdrawal symptoms which may include nausea, muscle aches, fatigue, jittery or anxious feeling, and headache, just to name a few. Patients should always discuss discontinuing these medications with their provider to ensure the proper time to discontinue and to discuss a slow taper of these medications.
