When you start treatment for depression, your doctor will tell you when you might start to feel better. Be sure to follow your doctor's instructions about:
You may start to feel better within 1 to 3 weeks of taking antidepressant medicine. But it can take as many as 6 to 8 weeks to see more improvement. If you have questions or concerns about your medicines, or if you do not notice any improvement by 3 weeks, talk to your doctor.
When you first start an antidepressant, you may experience side effects of the medicine. Many of the side effects are temporary and go away with continued use of the medicine, although some (such as dry mouth, constipation, and sexual effects) may continue.
Taking your medicine for at least 6 months after you feel better can help keep you from getting depressed again. If this is not the first time you have been depressed, your doctor may want you to take these medicines even longer.
Antidepressant medicines may need to be started at low doses and increased gradually, especially in most older adults. Medicines should also be stopped gradually by decreasing the dose over a period of time. If certain antidepressant medicines are stopped abruptly, you may suffer negative effects or the symptoms of depression may return.
Older adults or others who are depressed and taking several medicines for other health conditions (not related to depression) need careful monitoring of their medicines. People are more likely to develop harmful side effects from taking many different medicines.
