Do You Need Progesterone With Estriol Cream or Vagifem?

If you have been prescribed vaginal oestrogen, you may be wondering whether you also need progesterone, particularly if you still have your womb or are already using HRT.

For most people, low-dose vaginal oestrogen does not require additional progesterone. However, this is different from systemic oestrogen HRT, such as patches, gel or tablets, where progesterone or another form of progestogen is usually needed if you still have a womb.

Understanding the difference can help you use your treatment safely and avoid making changes to your HRT without appropriate advice.

What are estriol cream and Vagifem used for?

Estriol cream (0.01% and 0.1%) and Vagifem are forms of local vaginal oestrogen. They are used to relieve symptoms associated with reduced oestrogen levels during and after menopause, including:

Vaginal dryness
Burning, itching or irritation
Vaginal soreness
Discomfort or pain during sex
Reduced lubrication
Some urinary symptoms associated with menopause

Vagifem contains estradiol and is supplied as a vaginal tablet. Estriol cream contains estriol and is applied inside the vagina.

Both treatments work mainly in the vaginal tissues rather than providing oestrogen throughout the body.

Do you need progesterone with Vagifem or estriol cream?

Usually, no.

Low-dose vaginal oestrogen is absorbed mainly in the vaginal tissues, with only a small amount entering the bloodstream. Because of this, additional progesterone is not usually required to protect the womb lining.

This applies to low-dose vaginal oestrogen products such as:

Vagifem vaginal tablets
Estriol vaginal cream
Other low-dose vaginal oestrogen tablets, pessaries, gels and rings

NHS guidance confirms that vaginal oestrogen can generally be used without a progestogen, even if you still have your womb.

Why is progesterone needed with some HRT but not vaginal oestrogen?

The key difference is where the oestrogen works and how much reaches the rest of the body.

Systemic oestrogen can stimulate the womb lining. Progesterone, or another suitable progestogen, is used to provide endometrial protection and reduce the risk of the lining becoming too thick.

Low-dose vaginal oestrogen does not generally produce the same level of stimulation, so additional progesterone is not normally required.

What if you are already using HRT patches or gel?

If you are using systemic HRT, such as an oestrogen patch or gel, and still have vaginal symptoms, vaginal oestrogen may be added.

In this situation:

You should continue taking your prescribed progesterone or progestogen alongside systemic HRT if you still have your womb.
Vaginal oestrogen does not replace the progesterone required for systemic HRT.
You do not usually need an extra dose of progesterone simply because vaginal oestrogen has been added.

For example, if you use an oestrogen patch with micronised progesterone, you should continue your prescribed progesterone regimen unless your healthcare professional advises otherwise.

Does it matter if you still have your womb?

Yes, but the answer depends on the type of oestrogen treatment.

If you are using only low-dose vaginal oestrogen

You will usually not need additional progesterone, even if you still have your womb.

If you are using systemic oestrogen HRT

If you still have your womb, you will usually need progesterone or another suitable progestogen to protect the womb lining.

If you have had a total hysterectomy

You will usually not need progesterone with systemic oestrogen HRT because there is no womb lining to protect. However, individual circumstances may differ, so your prescribed HRT should not be changed without medical advice.

What does the research and guidance say?

NICE recommends vaginal oestrogen for genitourinary symptoms associated with menopause and states that it can be used alone or alongside non-hormonal moisturisers and lubricants.

NHS guidance confirms that little vaginal oestrogen enters the rest of the body, meaning a progestogen is not usually required.

British Menopause Society guidance also states that low-dose vaginal oestrogen does not require additional systemic progestogen for endometrial protection. This is different from systemic HRT, where the dose and duration of progestogen must be appropriate for the amount of oestrogen being used.

Can vaginal oestrogen affect the womb lining?

At licensed low doses, vaginal oestrogen is not generally associated with significant stimulation of the womb lining.

However, you should seek medical advice if you experience:

New or unexplained vaginal bleeding
Persistent bleeding after starting treatment
Unusual pelvic pain
Symptoms that are worsening rather than improving

Any unexplained vaginal bleeding should be assessed, particularly after menopause.

Is vaginal oestrogen safe for everyone?

Although vaginal oestrogen is low dose and mainly local, it is still a prescription treatment and may not be suitable for everyone.

Speak to your healthcare professional before starting treatment if you:

Have had breast cancer or another oestrogen-sensitive cancer
Are taking an aromatase inhibitor
Have unexplained vaginal bleeding
Have a history of blood clots
Have liver disease
Are pregnant or think you may be pregnant
If you have a history of breast cancer, particularly if you are taking an aromatase inhibitor, vaginal oestrogen should be considered with appropriate specialist input.

Important Information

Low-dose vaginal oestrogen, including Vagifem and estriol cream, usually does not require additional progesterone even if you still have your womb.

However, if you are also using systemic HRT, such as oestrogen patches or gel, you must continue using the prescribed progesterone or progestogen needed to protect your womb lining.

Vaginal oestrogen does not replace the progesterone required with systemic HRT, and you should not change or stop your prescribed HRT without medical advice.
