Progesterone and changes in taste or smell
Changes in taste (dysgeusia) or smell (parosmia, anosmia) are an under-recognised side effect category. Some medications produce a metallic taste, a dulling of flavours, or unusual smell perception. Whether Progesterone (Progesterone) at 100mg, 200mg causes these changes depends on Progesterone; the experience is usually benign but can affect appetite and quality of life.
Why taste and smell change on Progesterone
Taste and smell perception relies on receptors in the tongue and nose that are sensitive to systemic medications. Progesterone can affect taste through several mechanisms: alteration of saliva composition, direct receptor interference, secretion in saliva of medication metabolites, or changes in zinc handling. Progesterone binds to progesterone receptors and modulates gene expression in reproductive and other tissues.
When changes need attention
Mild metallic taste or dulled flavours in the first weeks of Progesterone at 100mg, 200mg are common and often resolve as the body adjusts. Persistent severe loss of taste or smell, sudden onset, or interference with eating warrants prescriber review — both because the medication may need adjustment and because other causes (zinc deficiency, sinus disease) should be excluded.
