A surprising number of women who conclude hormone therapy does not work for them are using it in a way that limits how much gets in. Nobody explains the practical side — where to put it, what stops it absorbing, why the patch keeps peeling off in July. Here is the part the leaflet covers badly.

Where we stand: Menova is an independent publication. We sell no hormones, we are not your doctor, and this is general education, not medical advice. Follow the instructions for your specific product and prescriber — brands differ, and where this article and your leaflet disagree, the leaflet wins.

Why the route matters

Transdermal estrogen — through the skin — bypasses first-pass liver metabolism. That is why it is not associated with the same clot risk as oral estrogen, and why it is often preferred where clot risk, migraine, or blood pressure are considerations. See HRT and blood clot risk and HRT types and forms.

The trade-off is that it depends on application, and application varies far more between people than swallowing a tablet does.

Patches

Where. Below the waist — buttock, hip, or lower abdomen are the usual sites. Not on the breasts. Follow your product's instruction; some specify particular areas.

Rotate sites. Do not put the new patch exactly where the last one was. Skin gets irritated, and irritated skin absorbs unpredictably.

Apply to clean, dry, cool skin. No moisturiser, oil, or talc on the area — this is the single most common reason patches fall off. If you have just showered or exercised, wait until skin is completely dry and no longer warm.

Press it for about ten seconds, especially the edges.

Avoid skin folds and the waistband where clothing rubs.

If it falls off: most products can be reapplied if it is still sticky; if not, apply a new one and keep your original change day. Check your leaflet — this differs by brand.

Heat is the enemy. Saunas, hot baths, heat pads, and hot weather all increase absorption and reduce adhesion. Two things follow: patches peel more in summer, and a heat pad directly over a patch is not a good idea.

If they will not stay on, say so. Adhesive quality differs substantially between brands, and switching brand is a normal request rather than a fuss. Some women use a breathable adhesive film dressing over the patch — ask your pharmacist whether that is appropriate for your product.

Gel

Measure it properly. Pumps and sachets are dosed. "About a squeeze" is not a dose, and inconsistent amounts produce inconsistent levels.

Where. Usually the upper arm and shoulder, or the inner thigh, depending on the product. Not on the breasts, and not on broken skin. Use a large area rather than a small patch of skin — the surface area matters.

Let it dry completely — this often means several minutes — before dressing. Getting dressed over wet gel puts your dose on your shirt.

Wash your hands afterwards. Estrogen gel transfers to other people through skin contact, which matters if you have young children or hug a partner shortly after applying.

Do not apply moisturiser to the same area for at least an hour either side.

Be consistent about the site. Absorption differs between body areas, so alternating between arm and thigh introduces variability you do not need.

Same time each day.

Spray

Same principles: a measured number of sprays, applied to the specified area — typically the inner forearm — allowed to dry fully, hands washed, no moisturiser on the area, and consistency about site and timing.

The progestogen half

If you have a uterus, estrogen must be balanced with a progestogen to protect the lining of the womb. This is not optional and not a detail — skipping it is the one mistake with real consequences.

Take it as prescribed, whether that is continuous or for a set number of days per cycle. If it makes you feel worse — low mood, bloating, breast tenderness — that is a reason to discuss changing the type, dose, or route, not a reason to stop taking it. A hormonal IUD is one option that delivers it locally. See progesterone in menopause.

What quietly reduces the dose you get

  • Moisturiser or sunscreen on the application area
  • A patch that came half off two days ago and was pressed back on
  • Gel applied to a small area, or rubbed until it disappears rather than allowed to dry
  • Gel washed off in a shower taken too soon afterwards
  • Very hot baths or saunas with a patch
  • Running out for a few days, repeatedly
  • Skipping days with gel

None of these is dramatic on its own. Together they are a plausible reason for "it stopped working."

If it is genuinely not working

Before concluding the treatment has failed, check the practical side above — then work through the clinical options in order: dose, route, progestogen, regimen. Our full guide is what to change when HRT isn't working, and expectations for the first weeks are in your first three months on HRT.

Also worth knowing: absorption genuinely differs between people. Some women need a higher transdermal dose than expected, and some do better on a different route entirely. That is a titration conversation, not a personal failing.

Practical extras

  • Travel. Keep hormones in hand luggage, take more than you need, and check rules for your destination — see menopause and travel
  • Surgery. Do not stop or continue on your own initiative — see HRT and surgery
  • Storage. Keep patches in their sealed sachets until use, and away from heat
  • A recurring reminder on your phone for patch change days, because "was it Tuesday?" is how gaps happen

What to ask

  • "Is my estrogen oral or transdermal, and is the route right for my risk profile?"
  • "Where exactly should I apply this, and how long before I dress?"
  • "What do I do if the patch falls off?"
  • "If adhesion is a problem, can we try a different brand?"

Our free printable visit prep sheet gives you a page for these, and the free 30-day symptom tracker shows whether your symptoms track with application problems — which is exactly the pattern to bring to a review.

The free 2-minute Menova self-check gives you a baseline to compare against — no account, not a diagnosis, and your answers never leave your device.
