Many medicines can be used to treat depression. These medicines are called antidepressants. They require a prescription from your doctor. They fix the chemical imbalance in the brain. They are not like tranquilizers.
Antidepressants work differently for different people.
They also have different side effects. So, if one medicine bothers you or doesn't work for you, another may be helpful. You may notice some effects of the antidepressant as soon as one week after you start taking it. But you probably won't see the full effects for about six to eight weeks. Your doctor may want you to take medicine for four months or much longer.
