Zoloft (sertraline) is a highly-efficient prescription medication used by patients diagnosed with a number of serious conditions, including sudden panic attacks, obsessive-compulsive disorder, posttraumatic stress disorder, as well as mood swings caused by some health conditions. If you are younger than 24 your doctor will ask you to show up for regular appointments during the first twelve weeks of taking this drug to make sure you do not have any suicidal thoughts as a result of Zoloft treatment. The risk of getting suicidal is higher if you have a family history of mania or bipolar disorder, as well as if you ever had similar thoughts before.
