I am a diabetic and also suffering from mild depression.

I am taking Escitalopram (Lexapro in US) 5 mg once daily for my depression. My pain doctor has put me on 25 mg of Nortriptyline once daily at night for my dental alveolar nerve pain . Is this combination dangerous ?

One is a TCA and the other SSRI. I am taking it for the past one month. I am just worried because i read these two cud cause Serotonin syndrome. However my doses are low.

Regards,
Amit.
