Myths vs facts: Progesteron and allergy

The relationship between progesterone and allergies is often misunderstood. There is some evidence that progesterone can modulate immune responses, and a rare condition called autoimmune progesterone dermatitis exists, where women develop allergic reactions (like hives or eczema) during the luteal phase of their cycle when progesterone is high. However, this is not common. The myth that progesterone generally causes or worsens allergies is not supported by strong evidence. Most studies are case reports or small observational studies, not large clinical trials. Additionally, estrogen also plays a role, making it hard to isolate progesterone's effect. For the average person, there is no need to avoid progesterone due to allergy concerns. If someone suspects a link between their menstrual cycle and allergy symptoms, they should consult an allergist or gynecologist. Hormone testing alone is not diagnostic for allergies. Overall, the evidence is mixed and context-dependent.
