“Like any medicine, the hormones used in hormone replacement therapy (HRT) can cause side effects. But it’s common to have no side effects or only mild ones.

Any side effects usually improve over time, so it’s a good idea to carry on with your treatment for at least 3 months if possible.

To help with side effects, a GP might suggest changing your dose, the type of HRT you take or how you take it. For example, switching from tablets to patches”.2

Side Effects

What can HT side effects include?

In Menopause Management Options: Menopausal Hormone Therapy (MHT) – Possible Side Effects of MHT the (Australian) Jean Hailes for Women’s Health (JH) note:

“Everyone responds differently to MHT. Some women may not experience any side effects, while others may have:

  • Nausea
  • Fluid retention
  • Bloating
  • Breast enlargement and discomfort
  • Vaginal bleeding
  • Weight gain.

Most symptoms settle within the first three months”.3

In Hormone Therapy for Menopause Symptoms: Risks/Benefits – What Are the Side Effects of Hormone Replacement Therapy (HRT)? the (United States) Cleveland Clinic explain:

“The most common side effects of hormone replacement therapy are:

  • Irregular vaginal bleeding
  • Breast tenderness
  • Mood swings

Less common side effects of hormone replacement therapy include:

  • Bloating
  • Headaches
  • Skin discoloration
  • Increased breast density, making mammogram interpretation more difficult
  • Skin irritation under the estrogen patch”.4

Side Effects of Oestrogen

What can side effects of oestrogen include?

In Hormone Replacement Therapy (HRT): Side Effects of Hormone Replacement Therapy (HRT): Side Effects of Oestrogen the NHS elaborate on:

“Side effects of taking oestrogen can include:

  • Headaches
  • Breast pain or tenderness
  • Unexpected vaginal bleeding or spotting
  • Feeling sick (nausea)
  • Mood changes, including low mood or depression
  • Leg cramps
  • Mild rash or itching
  • Diarrhoea
  • Hair loss

They will often go away after a few weeks”.5

Side Effects of Progestogen

What can side effects of progestogen include?

In Hormone Replacement Therapy (HRT): Side Effects of Hormone Replacement Therapy (HRT): Side Effects of Progestogen the NHS explain

“Side effects of taking progestogen can include:

  • Changes in your periods, including spotting or bleeding between periods
  • Headaches
  • Breast pain or tenderness
  • Feeling sick (nausea)
  • Diarrhoea
  • Feeling tired or dizzy
  • Mood changes, including low mood or depression
  • Mild rash or itchy skin
  • Acne

As with side effects of oestrogen, these will usually go away after a few weeks. There are things you can do to help cope with them”.6

Vaginal Bleeding

What is the association between vaginal bleeding and HT?

In Side Effects of Hormone Therapy In Women: Vaginal Bleeding the Cancer Research UK explain:

“Some hormone therapies can cause vaginal bleeding. It is most common when you first start hormone therapy, or if you switch from one treatment to another.

You might have:

  • A change to your usual periods
  • Bleeding between your periods
  • Bleeding after you periods have stopped
  • Tell your healthcare team if you have any of these”.7

Weight Gain

Is there an association between weight gain and HT?

In Hormone Replacement Therapy (HRT): Side Effects – Weight Gain and HRT the NHS note:

“There’s little evidence that most types of HRT make you put on weight.

You may gain some weight during the menopause and as you get older, but this often happens whether you take HRT or not.

Exercising regularly and eating a healthy diet should help you to lose any unwanted weight”.8

Temporary or Not

Are HT side effects temporary?

In The 2023 Practitioner’s Toolkit for Managing Menopause: Management – Effectiveness: Managing Clinical Side Effects of MHT Therapy, published online 30 October 2023, the authors explain:

“Initiating treatment with low-dose MHT will minimize the likelihood of adverse effects. Common adverse effects of estrogen include nausea (mostly limited to oral therapy) and breast tenderness. Breakthrough bleeding is not unexpected in the first 3 months of continuous-combined estrogen–progestogen therapy, and occasionally heavy bleeding can occur. Progestogen therapy may cause low mood or irritability. When this occurs either the dose needs to be reduced or another progestogen tried. Micronized progesterone may improve sleep and sometimes causes somnolence, and so should be taken at bedtime. Changing from one regimen to another in many cases will alleviate adverse effects.

Potential adverse effects of tibolone include fluid retention, mild weight gain and initial vaginal bleeding or spotting”.9

Health Care Provider

What if I need help with my HT side effects?

If you need help with your HT side effects, it may be in your best interest to choose to talk to your health care provider about this.

In Menopause Management Options: Menopausal Hormone Therapy (MHT): How Long Do You Need To Take MHT? the JH elaborate on:

Hormone Therapy Side effects“It can take around six months to find the right MHT. Once you’ve found an MHT that works for you, it’s important to review it with your doctor each year”.10

In The 2023 Practitioner’s Toolkit for Managing Menopause: Management – Effectiveness: Managing Clinical Side Effects of MHT Therapy the authors elaborate on:

“Optimally, women using systemic MHT should have a medical review at 3 months to assess symptom relief and side effects. This is also an opportunity to discuss any patient concerns and ensure correct use of the prescribed therapy”.11

In Postmenopausal Bleeding: Living With – When Should I Contact My Doctor? the (United States) Cleveland Clinic also note:

“Contact your healthcare provider if you experience any vaginal bleeding:

  • More than a year after your last menstrual period
  • More than a year after starting hormone replacement therapy (HRT)”.12
