Dear doctor, Recently my mother who is 70 and diabetic was prescribed Pristiq 50 mg at bed time by her neurologist because of chronic insomnia. She visited a neurologist for her spine related issue where upon asking about her chronic poor sleep pattern she was prescribed a tablet which has Desvenlafaxine 50 mg + Clonazepam 0.5 mg for 3 months. I want to know if it's safe for her to take this medicine in terms of addiction and other side effects? Her EGFR is borderline i.e. 60 ml/min. Her Thyroid parameters are normal and also Vitamin B12 and Vitamin D3 levels are normal as she takes supplements.
