Hi Preren,   Thank you for your question. Adderall and Lexapro should be okay to take together. The only interaction is a possible increase in the risk of developing serotonin syndrome. This is not a proven interaction. However if you experience agitation, tremors, rapid heartbeat, or other symptoms of serotonin syndrome, you should contact your doctor immediately. Adderall and Lexapro are commonly used in combination, and you should be okay to use these two medications together. However, if you take other medications, there may be interactions with those medications. Check with your doctor or pharmacist, or go to www.healthline.com/druginteractions to learn more.   Best of luck, Casey
