Although there are many antidepressants on the market, they all alter brain chemistry and as we are all individuals, this fundamental effect may not always be to return the patient to "normal". Drugs are not yet as sophisticated as we need them to be, but in the absence of easily accessible supportive emotional or psychological therapy, antidepressants are a logical "first aid" and a GP could just as easily be criticised for doing nothing if a patient presents with depression.
Another factor which seems to be overlooked when linking antidepressants to suicidal ideation is the fact that a deeply depressed person does not have the motivation to eat, dress, do anything - even to kill themself. The dangerous time is often when the antidepressants "kick in" and the patient begins to muster the energy to do something to end their misery. Although it does appear that the SSRI drugs are linked with a higher suicide rate, this could be because they are more effective at lifting mood and are better tolerated by the people taking them.
