Oestrogel is an oestrogen gel you apply to your skin daily. It releases estradiol through your skin, which bypasses your liver. It is prescribed for menopause symptoms such as hot flushes and night sweats. For most women the side effects of Oestrogel are mild, but experiences vary. What can you expect?
What is Oestrogel and how does it work?
Oestrogel is a transdermal gel containing estradiol, a body-identical form of oestrogen. You spread it daily onto clean skin of your arms or shoulders, where it is absorbed into your bloodstream. Because it uses your skin as its route, it does not pass through your liver first.
Each pump dose delivers 1.25 g of gel with 0.75 mg estradiol. You often start with one pump a day; your doctor can adjust this to the lowest dose that works for you. If you still have a uterus, a progestogen goes with it to protect your womb lining.
How much Oestrogel do you use?
The dose of Oestrogel is measured in pump doses per day. Your doctor chooses the lowest effective dose and builds up if needed. The table below shows roughly what that means.
| Pump doses per day | Gel | Estradiol | When |
|---|---|---|---|
| 1 pump | 1.25 g | 0.75 mg | Usual starting dose |
| 2 pumps | 2.5 g | 1.5 mg | If effect is insufficient, with advice |
Apply the gel over a large area of skin, for example from wrist to shoulder, and let it dry for a few minutes. Do not wash the area for the first hour and avoid direct skin contact with others.
Oestrogel experiences: what do users say?
Experiences with Oestrogel are mostly positive, though they differ from person to person. Many women value that a gel is invisible and cannot come loose like a patch. Others take a while to find the right dose or the handiest time of day.
Positive experiences: a clear drop in hot flushes and night sweats, invisible use, fine dose control per pump, better sleep and a more stable mood.
Points women mention: remembering it daily and waiting for it to dry, tender breasts in the first weeks, mild skin irritation, and a 4 to 12 week wait for the full effect.
Picture two women of 51 with the same hot flushes. One is glad she can dose the gel easily and stays on it for years. The other finds the daily application awkward and switches to a patch. The same goal, a different preference.
Side effects of Oestrogel
Most side effects of Oestrogel are mild and often settle within a few months as your body adjusts. Common side effects include tender or swollen breasts, headache, nausea and irregular bleeding. Fluid retention or a small weight change also occurs.
Less commonly reported are mood changes and skin irritation at the application site. If complaints stay bothersome, discuss it with your doctor rather than stopping on your own. Seek advice sooner for a painful swollen leg, breathlessness or chest pain.
Benefits and points to consider
Oestrogel shares its main benefit with other transdermal forms: because it bypasses your liver, the risk of blood clots is lower than with oestrogen in tablet form. Research in the BMJ (2019) showed that oestrogen through the skin was not linked to a raised thrombosis risk.
One point to consider is transfer: do not let others touch the application area in the first hour, especially children. And because Oestrogel contains oestrogen only, with a uterus you always need a progestogen alongside it, such as Utrogestan.
Alternatives to Oestrogel
If a gel does not suit you, there are other ways to take oestrogen through your skin or as a tablet. The choice depends on your preference and health.
- A Lenzetto spray or estradiol patch, also transdermal
- A combined tablet such as Femoston, with oestrogen and progestogen in one

Testing your hormones before and during Oestrogel
Before you start Oestrogel, a hormone test can give your doctor a starting point. Values often looked at are oestradiol, FSH and your thyroid (TSH), because thyroid complaints can resemble menopause symptoms.
A check of your oestradiol during use can help fine-tune the dose. With the Menopause blood test from Lunara you can discover your hormone levels, with an assessment by a BIG-registered doctor.
Frequently asked questions
Where do you apply Oestrogel?
Spread Oestrogel over a large, clean, dry area of skin, usually your arms or shoulders. You can alternate sites. Do not apply it to your breasts or near mucous membranes.
How quickly does Oestrogel work?
Hot flushes often ease within a few weeks. The full effect on sleep and mood can take 4 to 12 weeks. If you notice little difference after three months, discuss the dose with your doctor.
Do I need progesterone alongside Oestrogel?
If you still have a uterus, your doctor always prescribes a progestogen alongside Oestrogel to protect your womb lining. If you no longer have a uterus, it is usually not needed.
Can I swim or shower after applying it?
Wait at least an hour after applying before getting the skin wet or covering it, so the gel has time to absorb.
Oestrogel is a comfortable way for many women to take oestrogen through the skin, with the flexibility to dose per pump. Still, no single form is the best: the right choice is the one that suits your body and your day. Discuss your preferences openly with your doctor.
Every blood test result includes a professional assessment from a BIG-registered doctor. For treatment decisions, discuss your results with your GP.
