PLEASE check the ingredients in your HRT creams! It’s a topical product that goes on your skin and goes directly in your blood stream. (I believe that’s the point of using the topical HRT stuff!)
Personally, I use bio-identical hormone therapy. it’s more natural and apparently the safe alternative to regular cancer-causing HRT’s.
Many of the HRT creams will have plant oil, gel or extract in them (Salicylates) and will block your Guaifenesin from doing it’s job. You will need to talk to your doctor and pharmacist about this and make sure you have a list of all the ingredients that will go into your creams. You can ask the pharmacist to use the salicylate-free Galaxal Base cream for your hormone creams, this is a common base cream in most pharmacies in Canada and the States.
These are the oils that are ok: CROWS: Corn Rice Oat Wheat Soy. Any of those oils are fine to use in the creams.
