Calcium is unique among metals because its ions have a very large concentration gradient across the plasma membrane of all cells, from 10 â3 M Ca 2+ outside, to 10 â7 M Ca 2+ inside.

Discontinuation symptoms can include anxiety and depression. 1  Since these may be the reason you were prescribed antidepressants in the first place, their reappearance may suggest that you're having a relapse and need ongoing treatment. Here's how to distinguish discontinuation symptoms from relapse: Discontinuation symptoms emerge within days to weeks of stopping the medication or lowering the dose, whereas relapse symptoms develop later and more gradually. Discontinuation symptoms often include physical complaints that aren't commonly found in depression, such as dizziness, flulike symptoms, and abnormal sensations. Discontinuation symptoms disappear quickly if you take a dose of the antidepressant, while drug treatment of depression itself takes weeks to work.
