@heycal Low sodium can be dangerous, as @gloaming described below. One of the things that can cause it is diuretics for blood pressure control (Hydrochlorothyizide or Hcl, alone or in other meds.)
Sometimes a medication that worked in the past begins to cause unwanted side effects, and needs to be changed. Also, changes in another medication (or supplement), weight or diet can change how a medication affects you.

What would I do? By all means, get it checked again. If there are questions about interactions, ask for a complete med review by a Clinical Pharmacist or Medication nurse, and tell them EVERYTHING you take, Rx, OTC, supplements, botanical or herbal preparations, alcohol. They have training, experiences and detailed interaction checking software. At our clinic, this service is offered once a year to anyone who takes 5 or more medications.

Has anyone ever performed a med check for you?
