if lexapro (escitalopram) caused insomnia then it is better to take the drug in the morning after breakfast. this drug is an ssri drug (selective serotonin reuptake inhibitor) and helps to reduce depressive symptoms when taken regularly. buspirone is an anti-anxiety drug that helps to reduce the symptoms. in my opinion lexapro is the better choice for mixed anxiety and depressive symptoms. for further doubts consult a psychiatrist online --> <link>
does lexapro take a long time to start working?
