Lexapro (escitalopram) is an efficient drug prescribed for depression and anxiety disorder. This is a serotonin reuptake inhibitor that works by increasing the amount of serotonin in your brain therefore correcting its imbalance. Lexapro should be taken regularly and you may need several weeks to notice the first benefits of the treatment. Make sure you let your doctor know if you have liver disease, heart disease, thyroid disease, seizures, a recent history of heart attack, kidney disease, and any other ones you think are important to mention. There is no need to be worried if you get constipation, increased appetite, nausea, diarrhea, stomach pain, runny nose, drowsiness, heartburn, dizziness, or dry mouth, as all of them are mild side effects. More serious side effects are also possible and include fever, sweating, confusion, muscle stiffness, unusual excitement, hallucinations, or irregular heartbeat. Make sure you never take more of Lexapro. If you took more of this drug than recommended and experience seizures, confusion, tremor, dizziness, fast or pounding heartbeat, drowsiness, sweating, nausea, or vomiting, seek emergency medical help.
