“What are the long term side effects of consuming Primordial N tablets?”

Probably nothing serious, but consult your doctor also.

Primolut N is a progesterone pill. Short term side effects are common like nausea, headaches, vaginal spotting and breast tenderness. I do not expect you to have any long term side effects, assuming you are healthy. If you have any concerns please discuss with your OBGyn.
Take care!

I would absolutely not take this medication. It is a synthetic progestin and not progesterone. Progestins have been shown to cause multiple issues including an increase in blood clotting, heart and possibly stroke issues and an increase in breast cancer. These progestins are often incorrectly referred to as progesterone which they are not. They are modifications of the progesterone molecule. Naturally formulated bioidentical progesterone cannot be patented and therefore, pharmaceutical companies must change the molecule in order to get a patent. In my practice, I use progesterone which can be obtained by prescription in your local drug store as Prometrium or it can be compounded by a compounding pharmacist, which is what I do.

You may have cycle irregularity for a time when you come off this medication.
