What are the side effects of hormone replacement therapy?

Question

Hello doctor,

I am a 50-year-old woman going through menopause, and I have recently started getting frequent hives—itchy red welts that come and go, especially at night or during stress. My doctor said it could be chronic urticaria, but I wonder if menopause is playing a role. Is there a connection between hormonal changes and hives? I have not changed my diet or laundry detergent, so I’m confused. Antihistamines help a bit, but the hives keep returning. Should I get hormone levels checked? Could HRT (hormone replacement therapy) help or make it worse? I am so uncomfortable and just want to figure out what is going on.

Kindly help.

Hello,

Welcome to icliniq.com.

I read your query and can understand your concern.

Hormonal changes during menopause can contribute to skin sensitivity and may be a trigger for chronic urticaria (recurrent hives lasting more than 6 weeks). Estrogen plays a role in stabilizing mast cells (which release histamine, the chemical behind hives), so falling hormone levels around menopause may make your skin more reactive.

Here’s what you need to know:

Menopause and hives: Though not extremely common, some women do develop or worsen hives during menopause due to hormonal fluctuations. Emotional stress, poor sleep, and heat (from hot flashes) can also be triggers.

Diagnosis: Chronic urticaria is typically diagnosed when hives persist or recur for over six weeks, and no clear allergic cause is found. If your doctor has not already, checking thyroid function and autoimmune markers may help rule out other triggers.
Hormone testing & HRT: It is reasonable to discuss checking your hormone levels (especially if you have other symptoms like hot flashes, mood swings, or sleep disturbance). Hormone Replacement Therapy (HRT) may help balance your system and indirectly reduce symptoms in some women, but it can be a double-edged sword. HRT may improve or worsen hives depending on your sensitivity, so any trial should be closely supervised.
Management: A daily non-sedating antihistamine like Cetirizine or Fexofenadine (medicines that reduce allergy) is typically first-line. In stubborn cases, doctors may add a second antihistamine at night or medications like Montelukast or Omalizumab (a biologic for chronic hives).

Menopause can indeed affect your skin and immune responses. A collaborative approach with a dermatologist and your primary care or menopause specialist can help to find a solution that relieves your symptoms and improves your quality of life.

I hope this information helps you.
