i checked them in the interaction checker and found this: serious - use alternative: potential for serious interaction; regular monitoring by your doctor required dextromethorphan + lexapro oral lexapro oral and dextromethorphan both increase affecting serotonin levels in the blood. too much serotonin is a potentially life-threatening situation. severe signs and symptoms include high blood pressure and increased heart rate that lead to shock. <link>
can lexapro be taken simultaneously with dextromethorphan hbr. i had acute endo carditis (2004) and had emergency surgery to replace my mitral valve with a porcine valve. i am now 71 and have a viral infection that is not responding to a z pac. i started on adult tussin dm nd mucinex this morning. worried that this may not be good for me because i take lexapro 10 m daily
