Your friend has been diagnosed with an episode of MDD. She is 17 years old, very quiet and shy. She is the only child in the family. As it turns out, she has been having suicidal thoughts lately, although to an outside observer everything in her life seems to be perfectly normal—regular problems of an average teenager. The doctor has prescribed her Fluoxetine. She has started to take it but it has resulted in severe headaches.

Of course it is up to the doctor to decide, but do you think it is recommended for her to continue medication and for how long? What information do you think is necessary to make this decision?
