Lenzetto is a Hormone Replacement Therapy (HRT). It contains the female hormone estrogen. Lenzetto is used in postmenopausal women when at least 6 months have passed since their last natural menstrual period.
Lenzetto may also be used in women who have had surgery to remove their ovaries, as this causes instant menopause.
Lenzetto is a spray solution that contains small amounts of a medication called estradiol. When sprayed on the skin as directed, it passes through the skin into the bloodstream.
Lenzetto is used for:
Relief of symptoms that occur after menopause
During menopause, the amount of estrogen produced by the woman's body decreases. This can cause symptoms such as hot flashes in the face, neck, and chest ("hot flashes"). Lenzetto relieves these symptoms after menopause. Lenzetto will only be prescribed if your symptoms seriously interfere with your daily life.
Lenzetto is indicated for treating symptoms of estrogen deficiency after menopause, when menstruation no longer occurs after menopause. Symptoms of estrogen deficiency include hot flashes (sudden waves of heat and sweating throughout the body), difficulty sleeping, irritability, and vaginal dryness.
The experience in treating women over 65 years old is limited.
Lenzetto is not a contraceptive.
Medical History and Regular Reviews:
The use of THS involves risks that need to be considered when deciding whether to start using it, or to continue using it.
The experience in treating women with premature menopause (due to ovarian failure or surgery) is limited. If you have premature menopause, the risks of using THS may be different. Please consult your doctor.
Before starting (or resuming) THS, your doctor will ask you about your personal and family medical history. Your doctor may decide to perform a physical examination. This may include a breast examination and/or an internal examination, if necessary.
Once started on treatment withLenzetto, you should visit your doctor for regular check-ups (at least once a year). In these check-ups, discuss with your doctor the benefits and risks of continuing withLenzetto.
Undergo regular breast exams as recommended by your doctor.
Do not use Lenzetto
If any of the following situations apply to you. If you are unsure about any of the points below,consult your doctorbefore usingLenzetto.
Do not use Lenzetto
If any of the above conditions appear for the first time during the use of this medication, stop treatment immediately and consult your doctor immediately.
Warnings and Precautions
Consult your doctor or pharmacist before starting to useLenzetto.
Inform your doctor if you have ever had any of the following problems, before starting treatment, as they may recur or worsen during treatment withLenzetto. In that case, you should visit your doctor more frequently for check-ups:
Stop treatment withLenzettoand see a doctor immediately
If you observe any of the following symptoms while using THS:
For more information, see “Blood clot in a vein (thrombosis)”.
Note: Lenzetto is not a contraceptive. If you have had a menstrual period in the past 12 months or are under 50 years old, you may still need additional contraceptive measures to prevent pregnancy. Ask your doctor.
THS and Cancer
Endometrial Hyperplasia and Endometrial Cancer
THS with only estrogen will increase the risk of endometrial hyperplasia and endometrial cancer.
Taking a progestogen in addition to estrogen for at least 12 days of each 28-day cycle will protect you from this additional risk. Therefore, your doctor will prescribe a progestogen separately if you still have a uterus. If you have had a hysterectomy, consult your doctor to see if you can use this medication safely without progestogen.
In women with a uterus and not treated with THS, on average, 5 out of 1,000 will be diagnosed with endometrial cancer between the ages of 50 and 65.
In women aged 50-65 with a uterus and on THS with only estrogens, between 10 and 60 women out of 1,000 will be diagnosed with endometrial cancer (i.e., between 5 and 55 additional cases), depending on the dose and duration of treatment.
Lenzetto contains a higher dose of estrogen than other THS products with only estrogen. The risk of endometrial cancer when using Lenzetto with a progestogen is unknown.
Unexpected Bleeding
You will have a monthly bleeding (called withdrawal bleeding) while using Lenzetto if combined with a sequential progestogen dose. However, if you have unexpected bleeding or small losses (spotting) in addition to your monthly bleeding, which:
see your doctor as soon as possible.
Breast Cancer
It has been demonstrated that hormone replacement therapy (HRT) with estrogen-progestogen or estrogen-only HRT increases the risk of breast cancer. The additional risk depends on the duration of HRT use. The additional risk becomes apparent within 3 years of use. After stopping HRT, the additional risk will decrease over time, and may persist for 10 years or more if HRT has been used for more than 5 years.
Comparison
In women aged 50-54 who do not use HRT, on average, 13-17 out of 1,000 will be diagnosed with breast cancer over a 5-year period.
In women aged 50 who start using estrogen-only HRT for 5 years, there will be 16-17 cases per 1,000 users (i.e., 0-3 additional cases).
In women aged 50 who start using estrogen-progestogen HRT for 5 years, there will be 21 cases per 1,000 users (i.e., 4-8 additional cases).
In women aged 50-59 who do not use HRT, on average, 27 out of 1,000 will be diagnosed with breast cancer over a 10-year period.
In women aged 50 who start using estrogen-only HRT for 10 years, there will be 34 cases per 1,000 users (i.e., 7 additional cases).
In women aged 50 who start using estrogen-progestogen HRT for 10 years, there will be 48 cases per 1,000 users (i.e., 21 additional cases).
Examine your breasts regularly. See your doctor if you notice any changes, such as:
Additionally, you are advised to join screening programs when offered. For mammography, it is essential to inform the nurse/healthcare professional performing the radiography that you are using HRT, as this medication may increase the density of your breasts, which may affect the mammography results. When breast density increases, it is possible that mammography may not detect all lumps.
Ovarian Cancer
Ovarian cancer is rare, much less common than breast cancer. The use of HRT with estrogens alone or with a combination of estrogens-progestogens has been associated with a slightly higher risk of ovarian cancer.
The risk of ovarian cancer varies with age. For example, in women aged 50-54 who do not use HRT, approximately 2 cases of ovarian cancer per 2,000 women are observed over a 5-year period. In women on HRT for 5 years, approximately 3 cases per 2,000 patients are observed (i.e., approximately 1 additional case).
Effect of HRT on the Heart and Circulation
Blood Clots in a Vein (Thrombosis)
The risk ofblood clots in veinsis approximately 1.3 to 3 times higher in HRT users than in non-users, especially during the first year of treatment.
Blood clots can be serious, and if one breaks loose and travels to the lungs, it can cause chest pain, difficulty breathing, fainting, or even death.
You are more likely to develop a blood clot in your veins as you age and if you have any of the following situations. Inform your doctor if you have any of the following situations:
To know the signs of blood clots, see “Stop treatment withLenzettoand see a doctor immediately”.
Considering women aged 50 who do not use HRT, on average, 4-7 out of 1,000 will have a blood clot in a vein over a 5-year period.
In women aged 50 who have been using estrogen-progestogen HRT for 5 years, there will be 9-12 cases per 1,000 users (i.e., 5 additional cases).
In women aged 50 who have had a hysterectomy and have been using estrogen-only HRT for 5 years, there will be 5-8 cases per 1,000 users (i.e., 1 additional case).
Heart Disease (Myocardial Infarction)
There is no evidence that HRT prevents myocardial infarction.
Women over 60 who use estrogen-progestogen HRT are slightly more likely to develop heart disease than those who do not use HRT.
In women who have had a hysterectomy and are using estrogen-only HRT, there is no increased risk of developing heart disease.
Stroke
The risk of stroke is approximately 1.5 times higher in women treated with HRT than in those who are not treated. The number of additional stroke cases due to HRT use will increase with age.
Comparison:In women aged 50 who do not use HRT, on average, 8 out of 1,000 will have a stroke over a 5-year period. In women aged 50 who use HRT, there will be 11 cases per 1,000 users in 5 years (i.e., 3 additional cases).
Other Conditions
HRT does not prevent memory loss. There is some evidence of a higher risk of memory loss in women who start using HRT after the age of 65. Consult your doctor.
Children
The estradiol aerosol can be accidentally transferred from the skin where it has been sprayed to other people. Do not allow other people, especially children, to come into contact with the area of your skin where the estradiol was sprayed, and cover the area if necessary, after the spray has dried. If a child comes into contact with the area of your skin where estradiol was sprayed, wash the child's skin with water and soap as soon as possible. Due to the transfer of estradiol, young children may show signs of unexpected puberty (such as breast development). In most cases, symptoms will disappear when children stop being exposed to the estradiol aerosol.
Consult your doctor if you notice any signs or symptoms (breast development or other changes) in a child who may have been accidentally exposed to the estradiol spray.
Other Medications and Lenzetto
Inform your doctor if you are using, have used recently, or may need to use any other medication.
Some medications may interfere with the effect ofLenzetto. This can cause irregular bleeding. This occurs with the following medications:
HRT may affect how other medications work:
Inform your doctor or pharmacist if you are using or have used recently other medications, including over-the-counter medications, herbal medications, or other natural products.
Laboratory Tests
If you need a blood test, inform your doctor or laboratory personnel that you are using Lenzetto, as this medication may affect the results of some tests.
Pregnancy and Breastfeeding
Lenzetto is for use only in postmenopausal women. If you become pregnant, stop treatment with Lenzetto and contact your doctor.
Do not use Lenzetto while breastfeeding.
Driving and Operating Machinery
Lenzetto has no known effects on your ability to drive or operate machinery.
Lenzetto contains alcohol
This medication contains 65.47 mg of alcohol (ethanol) in each dose equivalent to72.74% v/v. It may cause a burning sensation on damaged skin.
Alcohol-based products are flammable. Keep away from fire. Avoid open flames, lit cigarettes, or the use of heat-producing appliances (e.g., hair dryers) while applying the spray to your skin until the medication spray has dried.

Your doctor will prescribe the lowest dose to treat your symptoms for as long as necessary.
During treatment, your doctor may adjust the dose according to your individual needs. Talk to your doctor if you consider the dose too strong or insufficient.
If you have not undergone a hysterectomy (surgical removal of the uterus), your doctor will give you some pills containing another hormone called progesterone to counteract the effects of estrogen on the uterine lining. Your doctor will explain how to take these pills. At the end of the treatment period with progesterones, a bleeding due to deprivation (see section "Unexpected bleeding") may occur.
If you need surgery
If you are going to undergo surgery, inform the surgeon that you are using Lenzetto. You may need to stop using Lenzetto about 4 to 6 weeks before the operation to reduce the risk of a blood clot (see section 2, Blood clots in a vein). Ask your doctor when you can start using Lenzetto again.
Where to apply Lenzetto
The aerosol must be applied to dry and healthy skin on the inside of the forearm. If not possible, it must be applied to the inside of the thigh.
Do not apply Lenzetto to the breasts or any area close to the breasts.
How to apply Lenzetto
Before using a new applicator for the first time, the pump must be primed by spraying three times with the cap on:The container must be held in a vertical position as shown in Figure 1. With the cap on, press the button down three times with your thumb or index finger.
The medication is now ready for use.
DO NOT prepare the applicator before each dose; prepare it only once before starting to use a new container. If you forgot one or more doses, prepare the applicator according to the instructions in the section "If you forgot to use Lenzetto".
Make sure the skin where you want to spray the medication is healthy, clean, and dry.
How to apply your daily dose.
To apply your daily dose, remove the plastic cap, hold the container in a vertical position, and press the flat plastic cone against the skin (Figure 2).
You may need to move your arm or move the cone along your arm so that the cone is flat on the skin and there are no gaps between the cone and the skin.
Press the button down once. It must be pressed firmly and held before releasing.
If you need another spray, move the cone along your arm so that it is next to the area you have already sprayed. Press the button down once.
If you need a third spray, move the cone along your arm again and press the button down once.
If the second or third spray does not fit in the same inside of the forearm, you can also spray on the inside of your other forearm. If you have trouble putting the cone on the inside of the forearm as shown in Figure 3, or if it is difficult for you to use it on your forearms, you can also spray on the inner surface of the thigh.
When you have finished using Lenzetto, always put the cap on the container (Figure 4).
If the medication is used as instructed, regardless of the different forms or patterns of administration on the skin, each spray will release the same amount of active ingredient.
Leave the spray to dry for at least 2 minutes before dressing and at least 60 minutes before bathing or washing. If the Lenzetto spray comes into contact with another area of the skin, such as the hands, wash that area of the skin with water and soap immediately.
Lenzetto cannot be used on injured or damaged skin.
Do not massage or rub Lenzetto on the skin.
Do not let others touch the area of the skin where the spray has been applied until it has dried and cover it with clothing 2 minutes after application, if necessary.If another person (especially a child) accidentally touches the area of your skin where you have sprayed Lenzetto, tell that person to wash the area of their skin with water and soap immediately.
How long to use Lenzetto
Your doctor will probably recommend the lowest dose initially (one spray per day) and you should talk to your doctor about how the medication is working for you. If necessary, your doctor may increase the dose to two sprays per day. The maximum daily dose is three sprays.
How often to use Lenzetto
You must apply the total number of sprays (dose) prescribed by your doctor at the same time every day.
How long to use Lenzetto
Talk to your doctor every 3-6 months about how long you should use Lenzetto. You should only use Lenzetto for as long as you need it to relieve hot flashes associated with menopause.
Other useful information
Sunscreen can alter the absorption of estrogen from Lenzetto.
Avoid using sunscreen on the area of the skin where you plan to spray. However, if you need to use sunscreen, you must apply it at least one hour before using Lenzetto.
Lenzetto should be used with caution in extreme temperatures, such as in a sauna or in the sun.
