I was just prescribed lexapro (escitalopram) 10 mg once daily. i also have been taking flexeril once daily. are these safe to take together?

They can interact: Both of these medications when taken together can increase your risk for serotonin syndrome or neuroleptic malignant syndrome. Symptoms can be found here: http://cpnp.org/resource/mhc/2013/09/differentiating-serotonin-syndrome-and-neuroleptic-malignant-syndrome or https://www.aacp.com/pdf%2F0512%2F0512ACP_Perry.pdf . Speak with your psychiatrist or PCP if you experience any such symptoms.
