Approved for medical use in 2002, Escitalopram-oxalate is an antidepressant that is mainly used to treat major depressive disorder or generalized anxiety disorder. This medication basically works by increasing the amount of the chemical serotonin in your brain. It is worth noting that having more serotonin helps decrease the symptoms of depression and anxiety. As far as the side effects of Escitalopram-oxalate are concerned, they may include trouble sleeping, nausea, sexual problems, and feeling tired. This medication also has more serious side effects such as suicide in people under the age of 25. It is, however, unclear if using it during pregnancy or breastfeeding is safe. You should take Escitalopram-oxalate by mouth with or without food as directed by your doctor. Remember that the dosage is based on your medical condition, response to treatment, age, and other medications you may be taking. So, be sure to tell your doctor and pharmacist about all the products you use.
