Key Takeaways
Understanding HRT patches vs pills: knowing the differences between delivery methods helps you make informed decisions about menopause treatment safety and effectiveness.
• Transdermal options (patches, gels, sprays) are safer than pills - They don't increase blood clot or stroke risk, while oral HRT nearly doubles VTE risk
• Patches offer convenience with twice-weekly changes - Most suitable for women wanting minimal daily routine disruption, though skin irritation affects 1 in 10 users
• Gels provide flexible dosing but require daily commitment - Easy dose adjustment makes them ideal for perimenopause, but need 1-hour contact avoidance after application
• NICE guidelines recommend transdermal as first-line treatment - Especially for women with BMI over 30, migraine history, or cardiovascular risk factors
• All delivery methods are available on NHS with annual prepayment certificates - Switching between methods is possible to find your optimal balance of safety and practicality
The choice ultimately depends on your medical history, lifestyle preferences, and tolerance for daily routines. Consult a menopause specialist to determine which delivery method best suits your individual circumstances and health profile.The choice between HRT patches and pills goes beyond convenience. Estrogen tablets activate liver clotting factors and cause a small increased risk of clot and stroke. Transdermal estradiol through a patch, gel or spray releases directly into the bloodstream with no increased risk of clot and stroke. This piece compares HRT gel and patches with pills and sprays. Readers can determine the best HRT delivery method. It covers how estrogen patches and other formats work, their benefits and drawbacks. Different health profiles and lifestyles suit different options.
HRT Patches: How They Work and What to Expect
What are HRT patches and how do they deliver hormones
HRT patches stick to the skin and release a constant, small amount of estradiol into the body every 24 hours [1]. Estradiol is the form of estrogen most used in hormone replacement therapy. The patches work transdermally, meaning hormones absorb through the skin and go straight into the bloodstream without passing through the digestive system [2].
Most patches are changed twice a week on the same days each week [3]. One patch stays on three days and the next four days. Changing on Monday and Thursday, then Monday again creates a continuous pattern with no breaks between patches [3]. Some brands require weekly changes instead [4].
Women still having regular periods should start using patches between day 1 and day 5 of their cycle [1]. Those experiencing infrequent periods or who have had a hysterectomy can start at any time [1].
UK brands: Evorel, Estradot, and Femseven
Three main estrogen-only patch brands are available on prescription through the NHS menopause services: Evorel, Estradot, and Femseven [5]. Each delivers different amounts of estradiol depending on the strength prescribed.
Evorel patches provide a steady release of estrogen and help maintain stable hormone levels [2]. Estradot patches come in various strengths including 25mcg, 50mcg, and 75mcg [6]. Femseven patches use estradiol hemihydrate and are worn for seven days before replacement [4].
Women who still have a womb need to take a separate progestogen among other estrogen-only patches to protect the womb lining [3]. Combined patches containing both hormones are also available, including Evorel Conti and FemSeven Conti [7].
Advantages of using estrogen patches
Patches offer several benefits compared to oral options when you think over the best HRT delivery method. They bypass digestion and make them gentler for those who experience stomach issues [2]. The steady hormone release maintains consistent levels throughout the day without the peaks and valleys seen with pills.
Patches carry a lower risk of blood clots compared to oral estrogen [2]. This makes them suitable for women with cardiovascular health concerns or those at higher risk of clotting especially.
Disadvantages and common challenges
Skin irritation at the application site affects more than 1 in 10 people [3]. The reaction presents as redness, itching, or rashes where the patch attaches to skin. Some women develop puffy, red skin at the patch site [3].
Patches fall off sometimes, especially after bathing, showering, or activities that cause sweating [1]. Applying moisturizer, sunscreen, body spray, or powder before patch application reduces adhesion [1]. The sticky residue left behind after removal can be annoying. Allow it to dry for 15 minutes, then rub it with baby oil or eye makeup remover to clear it away [1].
Other HRT side effects include breast tenderness, headaches, bloating, and abdominal pain [2].
How to apply HRT patches correctly
Skin must be clean, dry, and cool when you apply a patch [3]. Wait at least one hour after application before exercising or activities that cause sweating, as this affects how well the patch sticks [7]. Press the patch in place with your hand for about ten seconds, then rub the edges down [1].
Apply a new one to a different area if a patch falls off but keep to the original patch change days [3]. After bathing or showering, dry your skin and cool down before putting on a new patch [1]. The patches stay on during swimming, bathing, and normal daily activities [1].
Where to place patches on your body
Stick patches onto hairless skin below the waist, such as the buttock, thigh, or lower abdomen [1]. Most women prefer the thigh or bottom [3]. Rotate the application site with each new patch and wait at least one week before using the same spot again [1].
Never apply patches near breasts, on top of cuts or spots, on irritated skin, under elasticated or tight clothing areas, on skin creases or folds, or on skin exposed to direct sunlight [1]. Avoid areas where you used cream, talc, or moisturizer recently [1]. Tight waistbands may cause the patch edges to peel off [3].
Patches are available through standard NHS prescriptions alongside consultation with a menopause specialist for women concerned about HRT prescription costs.
HRT Gel: Oestrogel and Sandrena Explained
How HRT gel works through your skin
Estrogen gel contains estradiol, which absorbs through the skin into the bloodstream [3]. This transdermal delivery method means hormones bypass the digestive system. You apply the gel daily to clean, dry skin on areas like the upper outer arms, shoulders, or inner thighs [3].
Two main brands are prescribed in the UK: Oestrogel and Sandrena. Both contain body identical estradiol, the same chemical structure as the body's own menopause treatment hormone [8]. Estradiol is derived from plants such as yam or soy [8]. Once applied, the alcohol in the gel evaporates, enabling the estradiol to penetrate the skin barrier and enter circulation [3].
Benefits of choosing gel over other methods
Gel offers several advantages when weighing HRT gel vs patches. Like patches, estrogen gels do not increase the risk of blood clots [3]. This makes them suitable for women with menopause and cardiovascular health concerns or those managing menopause heart disease risk factors.
Women with migraines can use transdermal estradiol [8]. Estrogen tablets can increase Sex Hormone Binding Globulin (SHBG), which binds to testosterone and may reduce libido. Transdermal estradiol does not worsen libido [8].
The dose adjusts more easily compared to other options [8]. Younger women often need higher doses than older women during perimenopause and into postmenopause [8]. Most women use between two and four pumps of gel daily, though requirements vary [8]. This flexibility makes gel an appealing choice for the best HRT delivery method based on individual needs.
Drawbacks you should know about
Daily application can be harder to remember than patches, which change only twice weekly [8]. Gel application and allowing sufficient drying time proves more time-consuming than a patch [8].
Keep in mind, skin-to-skin contact must be avoided for at least one hour after application [3]. The gel can transfer to partners, children, or pets through direct contact [9]. If accidental contact happens, washing the affected area with soap and water prevents hormone absorption [9].
Women cannot wash the application area or apply other skincare products for at least one hour after use [3]. Washing the site one hour after gel application resulted in a 22% decrease in oestradiol concentrations [10]. Swimming requires waiting at least an hour after application [11].
The gels contain alcohol, which can cause burning on damaged skin or eczema [3]. Some women find gels messy when using multiple doses [3]. Others report the gel slides off or floats on skin rather than absorbing, depending on skin texture and thickness [3].
Correct application technique for maximum absorption
Apply gel to clean, dry, unbroken skin [10]. Spread it thinly over a large area rather than rubbing vigorously [9]. Despite package insert instructions, rubbing the gel into skin helps absorption [8].
Do not apply near breasts or genital areas [10]. The gel needs up to five minutes to dry before dressing [11]. Wash your hands with soap and water after application [9].
Rotate application sites to prevent tolerance in one spot and maintain better absorption [9]. Application after a warm shower helps, owing to increased microcirculation [9]. Avoid using moisturizers, sunscreen, or other products on the area for at least 30 minutes to one hour before or after gel application [3][9].
Pump packs vs sachets: What's the difference
Oestrogel comes in a pump dispenser containing 64 doses [3]. Each pump of Oestrogel must be primed five times before first use [12][9]. One complete press delivers the same measured amount each time [9].
Sandrena gel comes in sachets available in two strengths: 0.5mg and 1mg [3][11]. There is less gel volume for the same dose compared to Oestrogel, making it more practical for higher doses [3]. Sachets prove useful when traveling or keeping doses in a handbag [10].
UK availability and costs
Both Oestrogel and Sandrena are available on prescription through NHS menopause services and from a menopause specialist UK doctor. Women requiring ongoing HRT prescription cost UK management can purchase an HRT prescription prepayment certificate for £19.30 annually [13]. This certificate covers unlimited HRT items including gels for 12 months [13].
Women with a womb must combine estrogen gel with progesterone menopause treatment for at least 12-14 consecutive days per month to protect the endometrium [12].
HRT Pills: The Traditional Oral Method
How oral estrogen is processed in your body
Oral estradiol tablets pass through the digestive system where they undergo first-pass metabolism in the intestines and liver. About 95% of the dose metabolizes into estrone and estrogen conjugates before entering circulation [9]. The absolute bioavailability is around 5%, with a possible range of 0.1% to 12% [9].
This processing creates disproportionate estrogen levels locally in the liver, around 4 to 5 fold higher than in circulation [9]. Abnormally high estrogenic signaling occurs in the liver as a result and affects protein synthesis [9]. The liver produces extra clotting proteins and raises the risk of blood clots in legs or lungs [9]. Sex Hormone Binding Globulin (SHBG) also increases by around 50% [9], which binds to testosterone and may reduce sex drive [9].
High interindividual variability exists in estradiol levels achieved with oral estradiol, ranging from 28 to 127% between individuals [9]. Daily doses of 1mg produce circulating concentrations of 30 to 50 pg/mL estradiol and 150 to 300 pg/mL estrone in postmenopausal women [9].
Pills might still be the right choice
Oral HRT is more budget-friendly than other types of HRT [10]. Patient risk factors and preference should guide treatment options [10]. Women under 60 years starting HRT menopause treatment face very low baseline population risk of stroke [10].
Pills are convenient to women who prefer not to manage topical applications or those experiencing skin sensitivity with patches [9]. Women who have undergone hysterectomy receive estrogen-only tablets, whereas those with an intact uterus require combined estrogen-progestin therapy to prevent endometrial hyperplasia [9].
NICE guidelines prefer transdermal options
NICE recommends you think over transdermal rather than oral HRT to people with menopause symptoms who face increased risk of venous thromboembolism, including those with a BMI over 30 kg/m2 [14]. VTE risk is greater with oral than transdermal preparations [10].
Transdermal administration of estradiol is unlikely to increase the risk of venous thrombosis or stroke above that in non-users and carries a lower risk compared with oral administration [15]. These safety differences mean the transdermal route should be your first choice to administer estradiol in women with risk factors [15].
Risks associated with oral HRT
Oral HRT increases the risk of venous thromboembolism compared to baseline population risk [10]. This risk doubles from 1 in 1000 to 2 in 1000 adults per year, studies suggest [16]. Less than 1 in 100 women taking HRT developed a blood clot in their lungs over five years, about twice the number not taking HRT [16].
Oral estrogen is associated with a small increase in stroke risk [10]. 2 in 100 women not taking HRT have a stroke, while 3 in 100 women taking HRT will have one [16]. The risk appears increased in women taking estrogen-only or combined HRT, though not in women under 60 years old [16].
Common oral HRT brands in the UK
NHS menopause services provide several oral formulations. Zumenon contains synthetic estradiol in various strengths [13]. Combined HRT tablets include both estrogen and progesterone taken once daily [13]. Tibolone represents another tablet option that breaks down in the body to produce substances working like estrogen, progesterone and testosterone [13].
Women requiring ongoing prescriptions can access HRT prescription cost UK savings through prepayment certificates.
HRT Spray: The Newest Delivery Option
What is Lenzetto spray and how does it work
Lenzetto represents the only HRT spray available in the UK. Each spray contains 1.53mg estradiol [3], which absorbs transdermally into the bloodstream. The usual dose ranges from one to three sprays daily [9] [3], though some women need adjustments based on symptom control.
Application involves holding the container upright and resting the plastic cone against clean, dry skin on the inner forearm [9] [3]. Press the button once to release a single spray. For multiple doses, move the cone along the arm without overlapping previously sprayed areas [3]. The inner thigh serves as an alternative application site [3].
The spray dries within two minutes [9] [3], after which dressing can occur. Washing the area must wait at least one hour [9]. Swimming or bathing needs similar timing. Sun cream application needs to happen at least one hour before using Lenzetto [17].
Each device contains 56 sprays [17]. Marking off daily uses on the box helps track when replacement becomes necessary. Women with a womb need progesterone with Lenzetto for endometrial protection [17].
Pros and cons compared to gel and patches
Lenzetto spray dries faster than estrogen gels and leaves less skin residue [17]. The format suits women who dislike patches or find gels messy. As a transdermal delivery method, it carries a lower risk of blood clots compared to oral estrogen [17] [10]. The spray bypasses digestion and makes it gentler for those experiencing stomach issues [17].
The discreet, portable bottle allows easy transport and application anywhere [17]. Dose adjustment proves straightforward when symptoms change.
Absorption from Lenzetto spray can be unreliable [3]. This makes optimizing doses challenging for some women. The spray needs daily application at about the same time and demands consistent routine adherence. Skin-to-skin contact must be avoided for the first hour after use to prevent hormone transfer to partners or children.
Who might benefit from spray application
Women experiencing skin irritation from patches find spray application beneficial. Those who struggle with gel messiness or prefer faster drying times often choose this option. The spray format works well for women needing flexible dosing during perimenopause when hormone requirements fluctuate.
If reliable absorption occurs, spray represents a viable alternative within types of HRT. Women managing menopause treatment through NHS menopause services can discuss Lenzetto with a menopause specialist UK to determine suitability based on individual health profiles and lifestyle factors.
HRT Patches vs Pills vs Gel: Direct Comparison
Blood clot and stroke risk differences
Studies comparing HRT menopause delivery methods reveal major safety differences. Women taking oral HRT tablets face 58% higher likelihood of developing blood clots within 90 days compared to non-users [18]. Research found oral estrogen nearly doubles VTE risk (OR 1.90) [19]. Transdermal estrogen showed 56% risk reduction compared to oral use [19]. Patches, gels and creams do not increase VTE risk [20].
Stroke risk follows the same pattern. Current oral estrogen users experience 28% higher stroke rates (rate ratio 1.28) compared to non-users [21]. Transdermal oestrogens show no increased stroke risk (rate ratio 0.95) [21]. Direct comparison reveals transdermal users face lower stroke risk than oral users (rate ratio 0.74) [21]. These differences matter a lot when it comes to menopause and cardiovascular health concerns.
Convenience and daily routine to consider
Types of HRT vary quite a bit in application frequency. Patches require changes twice weekly or weekly depending on brand [22]. This makes them convenient to those who prefer minimal intervention. Gels and sprays need daily application [23] and demand consistent routine adherence. Pills involve once-daily dosing that's easy to incorporate into existing medication schedules [14].
Skin reactions and physical side effects
Skin irritation affects more than 1 in 10 patch users [15]. Gel users avoid adhesive reactions but face potential alcohol-related burning on damaged skin. Oral formulations bypass skin entirely but may cause nausea, bloating and breast tenderness [24]. All delivery methods share common HRT side effects like breast pain and headaches.
Cost comparison on the NHS
All menopause treatment options are available through NHS menopause services. The HRT prescription prepayment certificate costs £19.30 annually [25] and covers unlimited patches, tablets and gels for 12 months.
Best choice for different lifestyles
The menopause specialist UK approach takes individual circumstances into account. Active women who swim frequently may prefer gels over patches. Those with partners or children should note transdermal products require avoiding skin contact for one hour post-application. Women experiencing perimenopause benefit from gel doses that are easy to adjust, whereas postmenopause women often prefer patch convenience.
Which HRT Delivery Method Is Best for You
Medical history factors that matter
Several medical conditions influence the best HRT delivery method choice. Transdermal therapy suits women with BMI over 30 kg/m2, previous or family history of VTE, gastrointestinal disorders affecting oral absorption, variable blood pressure control, or gall bladder disease [26]. Women taking hepatic enzyme inducing medication benefit from types of HRT that bypass liver metabolism [26]. Those at high risk of VTE, such as those with strong family history or hereditary thrombophilia, require hematologist assessment before starting HRT menopause treatment [26].
Migraine sufferers and clotting risk
Women suffering migraines, especially when you have migraine with aura, face a higher baseline stroke risk [16]. Oral synthetic estrogen increases this risk further, hence migraine sufferers should avoid oral contraceptive pills [16]. Transdermal estrogen proves safest for menopause treatment as it does not affect clotting risk [16]. Worsening migraines in HRT users indicate increased ischaemic stroke risk by 30% [27]. Careful HRT selection to minimize hormone fluctuations matters for migraine management [16].
Skin sensitivity considerations
Patch users experiencing persistent skin reactions should try different brands before abandoning this delivery method [28]. Some women develop inflammation where patches adhere and this reduces hormone absorption effectiveness [28]. Gels contain alcohol, causing burning on damaged skin or eczema [29]. Those with extensive skin sensitivity may find oral HRT side effects more tolerable, provided they lack blood clot contraindications [22].
Partners or children at home: Transfer risks
Physical contact must be avoided for at least 60 minutes after applying estradiol gel [13]. Contamination levels peak 10 minutes after application and decline substantially at 60 minutes [13]. Exogenous estrogen causes precocious puberty in children [13]. Testosterone transfer produces genital enlargement in children through repeated accidental exposure [30]. Parents using topical hormones should wash hands after application, cover treated areas with clothing, and wash application sites before physical contact [30]. Patches eliminate transfer concerns for families with young children [31].
Can you switch between delivery methods
Women may try different HRT brands and delivery methods to find suitable options [23]. Absorption varies between individuals and body areas [29]. Patches failing to stick during swimming or bathing justify switching to gels [28]. When progesterone menopause symptoms persist, adjusting doses or changing methods resolves issues [28]. Healthcare professionals individualize NHS menopause services based on patient preference, adherence, safety and efficacy [32].
What NICE recommends as first-line treatment
NICE guidelines recommend offering menopause and cardiovascular health protective transdermal HRT rather than oral for those at increased VTE risk [26]. The transdermal route serves as first choice for estradiol administration in women with risk factors [9]. NICE emphasizes HRT as first-line treatment for vasomotor symptoms [33]. Decision-making requires individualized discussion of benefits and risks [9]. Treatment through a menopause specialist UK will give a tailored approach that thinks over perimenopause or postmenopause status.
Conclusion
Choosing between types of HRT requires weighing safety against convenience. Transdermal options like patches and gels offer lower blood clot and stroke risks compared to oral tablets. This makes them the preferred choice for most women. In fact, NICE guidelines recommend transdermal delivery as first-line treatment, especially for those with cardiovascular risk factors.
Each delivery method comes with trade-offs. Patches provide convenience with twice-weekly changes but may cause skin irritation. Gels allow flexible dosing yet require daily application. Pills prove easiest to remember but carry higher clotting risks.
Consult a menopause specialist to identify the best option for your health profile, lifestyle and symptom management needs. The right menopause treatment balances safety with practicality, and you can switch methods if your choice proves unsuitable.
FAQs
Q1. Do HRT patches carry a lower risk of blood clots than pills? Yes, HRT patches deliver hormones directly into the bloodstream through the skin, bypassing the liver. This means they don't increase the risk of blood clots or stroke, unlike oral tablets which activate liver clotting factors and carry a small increased risk of these complications.
Q2. How often do you need to change HRT patches compared to applying gel? Most HRT patches are changed twice weekly (every 3-4 days), while some brands require weekly changes. In contrast, HRT gel needs to be applied daily at roughly the same time each day, which requires more consistent routine adherence.
Q3. Can you switch from HRT pills to patches or gel if you experience side effects? Yes, you can try different HRT delivery methods to find what works best for you. Women may switch between patches, gels, and pills based on factors like skin reactions, convenience, or medical considerations. Healthcare professionals can help tailor the approach to your individual needs and preferences.
Q4. What should you avoid doing after applying HRT gel or spray? After applying HRT gel or spray, you must avoid skin-to-skin contact with others for at least one hour to prevent hormone transfer to partners or children. You should also wait at least an hour before washing the application area, swimming, or applying other skincare products to ensure proper absorption.
Q5. Why do NICE guidelines recommend transdermal HRT over oral tablets? NICE recommends transdermal HRT (patches, gels, or sprays) as first-line treatment because they carry a lower risk of venous thromboembolism and stroke compared to oral preparations. This is especially important for women with a BMI over 30 or other cardiovascular risk factors, as transdermal options don't increase clotting risk above baseline levels.
