Question:
Male, 25-years-old, unknown subtype
Son, aged 25, was previously taking Propranol for blood pressure and anxiety. We were noticing increased anxiety and PCP just switched him to Lisinopril and Venlafax ER 75. Are these 2 meds found to be safe for patients with PWS??
Nurse Lynn’s Response:
Unfortunately, your question is more complicated than a simple yes or no. We really need to understand his pharmacogenomics, which is how an individual’s genetic attributes affect the likely response to therapeutic drugs. You can ask your provider if GeneSight testing is available which can be helpful for the prescriber. Both propranol and venlafaxine are metabolized through 2D6, which is likely to be impaired in PWS (see linked article). Lisinopril typically treats high blood pressure not anxiety and is excreted through the kidneys. Your provider will be checking lab values to make sure that the values are within normal limits.
When you talk about increased anxiety, there is a lot to unpack there. We should attempt to understand the cause for this increase. Often a combination of things is the cause, change in routines, hormonal changes, seasonal changes and so on. It can be difficult for individuals with PWS to have the insight into their own behavior. Behavioral interventions should take a systemic perspective that seeks to understand the inter-relationships between developmental, biological, psychological and social factors.
