Hormone replacement therapy (HRT) - Side effects 

Side effects of HRT 

Reporting side effects

The Yellow Card Scheme allows you to report suspected side effects from any type of medicine you are taking.

It is run by a medicines safety watchdog called the Medicines and Healthcare products Regulatory Agency (MHRA).

Both hormones used in hormone replacement therapy (HRT), oestrogen and progestogen, have side effects.

Side effects usually improve over time, so try the treatment plan you have been prescribed for at least three months.

If side effects continue after this time, see your GP so your treatment plan can be reviewed.

If side effects persist, your GP may recommend:

  • switching to a different way of taking HRT, for example, changing from a tablet to a patch or vice versa
  • changing the type of HRT you are taking, for example, a different form of oestrogen or progestogen
  • changing the dose of your HRT

Side effects of oestrogen

Side effects associated with oestrogen include:

  • fluid retention
  • bloating
  • breast tenderness or swelling
  • nausea
  • leg cramps
  • headaches 
  • indigestion 

In some cases, small lifestyle changes can help to relieve side effects. For example:

  • taking your oestrogen dose with food may help to reduce nausea and indigestion
  • eating a low-fat, high-carbohydrate diet may reduce breast tenderness
  • regular exercise and stretching can help to reduce leg cramps

Side effects of progestogen

Side effects associated with progestogen include:

Hi all I was recommended to go on HRT in the 80s by my GP who never believed in taking drugs was more Homeopathic really, she said after I had a hysterectomy, she said that as long as I took them & went for my breast check ups,I could take them as long as I lived.She would never ever had said that if she did not mean it. I have for many years and changes of Doctors been tried to stop taking them. I have not & had no affect at all. Just wanted to know if many others are in same boat!

I have been on the continuous combined hrt for a month now. I'm experiencing the same type of premenstrual symptoms. Iv started a slight period two days ago. But as my flushes have improved I will try and persevere with the treatment.

I had a total hystorectomy last year and was put on prempak c. I have been suffering terrible headaches progressing into disturbed visions migranes, I have gained weight which upsets me as i have always been small. My skin is dreadful and i feel exhausted all of the time. I am only 38 years of age. I consulted my surgeon who said it was unlikely to be the hrt, but i have only been like this since being on it. Any help? Do you think i need to change my hrt and any suggestions to which one? I exercise all the time but no weight is dropping off.....:(

I have only been taking the combined form of HRT for 27 days but since day 1 I have felt as though I am going to start a period, ie; horrible period cramps and lower back pain. Plus side - the aches and pains in my joints have vanished, I have more energy, the hot flushes have vanished, my sex life has returned ( I was sore and dry - horrible! ) and my skin has plumped out and looks better.
The period pain is horrible though. Nothing touches it - cocodamol etc. I shall be interested to see what happens when I have my 'bleed'.
I'm 57 and had my last period 3 years ago. Sticking with the three month trial as the positives have been well worth the downside of the pain.
Anyone else experienced this? And if so, have you found a painkiller that works???

Weight gain

Many women believe taking HRT will make them put on weight, but there is no evidence that this is the case.

You may gain some weight during the menopause but this often happens regardless of whether you take HRT or not.

Exercising regularly and eating a healthy diet should enable you to lose any unwanted weight.

The MHRA has produced a video that explains how the Yellow Card Scheme can be used to report the side effects of medication
