Common questions about Delestrogen
Delestrogen isn't FDA-approved for in vitro fertilization (IVF). But fertility specialists sometimes prescribe estrogen injections, like Delestrogen, off-label to help thicken the uterine lining, preparing it for an embryo transfer. Follow up with your fertility specialist to find out more about the use of estrogen injections in IVF.
Estrogen injections, like Delestrogen, are sometimes prescribed off-label as part of estrogen-based gender-affirming hormone therapy (GAHT), also called feminizing hormone therapy. Guideline from the Endocrine Society lists Delestrogen as an option for GAHT and it's typically injected weekly or every two weeks. Talk with your healthcare team if you've more questions about Delestrogen and GAHT.
People who took progestin- and estrogen-containing HRTs in clinical studies, like Delestrogen, have reported mood changes as side effects. These included depression, nervousness, and irritability. It's unclear whether the changes in mood were caused by the HRT medications or by other conditions, such as menopause. In general, research shows that changes in hormones are linked to changes in moods. If you feel more anxious, contact your prescriber. They can help you find ways to manage anxiety or talk with you about other treatment options.
Tiredness isn't a side effect commonly reported by people who took HRTs in clinical studies. But Delestrogen might be linked to other side effects that can make you feel tired, such as depression or mood changes. Keep in mind that if you're taking Delestrogen to treat menopause, tiredness might be a symptom of menopause itself, especially if you're not sleeping well at night from hot flashes. If you feel more tired after starting Delestrogen, discuss possible causes with your healthcare professional.
Pain is a common side effect from injections, so you might feel pain in the buttocks area where Delestrogen is injected. If this bothers you, ask your prescriber about possible ways to manage pain, such as numbing cream that you can use before your injection or taking an over-the-counter pain reliever.
No, Delestrogen doesn't need to be refrigerated. You should store Delestrogen at room temperature, between 68 and 77 degrees F. If the medication gets cold, you might see some crystals form in the liquid. But these should go away once the medication is warmed back up to room temperature.
No. Delestrogen contains estradiol valerate, a form of estrogen, and is used for treating menopause, low estrogen levels, and pain from advanced prostate cancer. Depo-Provera (medroxyprogesterone) contains medroxyprogesterone, a form of progesterone, and is used as birth control and pain from endometriosis.

Risks and warnings for Estradiol valerate (Delestrogen) injection
Estradiol valerate (Delestrogen) injection can cause some serious health issues. This risk may be even higher for certain groups. If this worries you, talk to your doctor or pharmacist about other options.
Uterine or endometrial cancer
- Risk factors: Estrogen therapy without additional progestin | People with a healthy uterus | Using estrogen therapy for more than 1 year | High estrogen dose
Because estradiol valerate (Delestrogen) injection works like estrogen in your uterus, it can change the lining of your uterus (endometrium). Uncontrolled growth of the uterus lining can cause uterine or endometrial cancer in people with a healthy uterus. If you have a healthy uterus, your healthcare team will lower your risk of cancer by also prescribing a progestin to balance out estrogen's effect on the growth of the uterine lining. Let your healthcare team know right away if you have symptoms of uterine or endometrial cancer, such as unexpected vaginal bleeding; they can examine you and let you know if you need more medical attention.
Breast cancer
- Risk factors: Personal or family history of breast cancer | Using estrogen and progestin together for more than one year
Estrogen HRTs, like estradiol valerate (Delestrogen) injection, can raise your risk of breast cancer. Your risk is higher if you're also taking a progestin medication. Don't use estradiol valerate (Delestrogen) injection if you currently have or have had breast cancer in the past. To lower your risk of breast cancer, your HCP will prescribe the lowest dose of estrogen for the shortest period of time possible. It's important that you regularly check your breasts for any changes and get breast scans (mammograms) done. Let your healthcare professional know if you notice any unusual changes in breast shape, size, or color.
Blood clots, heart attacks, and strokes
- Risk factors: Personal or family history of blood clots | High blood pressure | Diabetes | High cholesterol | Smoking | Larger body size | Systemic lupus erythematosus (SLE)
Estradiol valerate (Delestrogen) injection can raise your risk of blood clots. The clots can happen in any area of the body and can lead to serious conditions, like heart attack, stroke, or pulmonary embolism. Your risk for blood clots is higher if you smoke or have had blood clots in the past. Be sure to discuss all your past and present medical conditions with your prescriber before starting estradiol valerate (Delestrogen) injection. Call 911 or get medical help right away if you have pain in your legs or arms, chest pain, sudden severe headaches, trouble breathing, or sudden changes in your speech or vision.
Risk of dementia
- Risk factor: Females 65 years of age and older
People taking estrogen/progestin combinations or estrogen-only therapy might be at greater risk for dementia. Your risk is higher if you start hormonal therapy after age 65. Estrogen/progestin combination and estrogen-only therapies shouldn't be used to prevent dementia. Early symptoms of dementia include new forgetfulness, confusion, getting lost, and wandering out into the neighborhood. If the risk of dementia worries you, talk to your HCP.
Gallbladder problems
Estradiol valerate (Delestrogen) injection can cause you to have problems with your gallbladder. Some people have even needed to have their gallbladder removed after starting this medication. If you experience stomach pain, nausea or vomiting that doesn't go away, fever, or a yellowing of the skin and eyes (jaundice), speak with your prescriber or get medical help right away.
Higher risk of side effects
- Risk factors: History of or current liver problems
Estradiol valerate (Delestrogen) injection is processed (broken down) by the liver, so if your liver isn't working properly, you might experience more side effects from this medication. Because of this, if you have or have had any problems with your liver, including liver problems during a past pregnancy, you shouldn't use estradiol valerate (Delestrogen) injection.
High triglycerides
- Risk factors: High levels of triglycerides
Estrogens can raise the amount of your body's blood fats (triglycerides), which can cause heart problems or inflammation of the pancreas. Your prescriber might order regular blood tests to watch for this while you're using estradiol valerate (Delestrogen) injection. If you experience sudden stomach or back pain, nausea, vomiting, sudden weight loss, or a fast heart rate, contact your prescriber or get medical care right away.
Vision problems
Although very rare, some people taking estrogens have had vision problems due to clot formation in the eyes. If you have sudden partial or complete vision loss, bulging eyes, double vision, or migraines, stop estradiol valerate (Delestrogen) injection and tell your HCP.
Changes in calcium levels in the blood
- Risk factors: Breast cancer | Cancer that has spread to the bones | Low parathyroid hormone levels
Estrogen therapy can change the calcium levels in your blood. Females with breast cancer that has spread to the bones are at higher risk of extremely high calcium levels. Symptoms of high calcium levels include feeling tired and having muscle weakness, nausea, vomiting, or constipation.
On the other hand, females with low parathyroid hormone levels from the parathyroid gland are at higher risk of low calcium levels during estrogen therapy. Symptoms of low calcium levels include muscle spasms or twitching and numbness and tingling in your fingers, toes, or around your mouth.
Let your HCP know if you notice any of these symptoms. You might need regular blood tests done so that your HCP can check your calcium levels while you're taking estradiol valerate (Delestrogen) injection.
Low thyroid hormone levels (hypothyroidism)
- Risk factors: Low thyroid hormone levels
Estradiol valerate (Delestrogen) injection can affect thyroid hormone levels in your blood. If you take medications for low thyroid hormone levels, you might require higher doses of thyroid replacement therapy. Your prescriber might have you perform regular blood tests to check your thyroid hormone levels.
Fluid Retention
- Risk factors: History of heart or kidney problems
Estradiol valerate (Delestrogen) injection might cause some fluid retention, or edema. This could worsen symptoms of certain conditions, like heart conditions (e.g., congestive heart failure) or kidney problems. If you notice unusual swelling in any part of your body or if you suddenly gain weight over a short period of time, let your prescriber know.
Worsening of other medical conditions
Taking estrogen-containing medications can worsen certain medical conditions. These include high blood pressure, hereditary angioedema, asthma, diabetes, migraine, and seizures. Before you start estradiol valerate (Delestrogen) injection let your healthcare team know about your past medical history so they can talk with you about the risks and benefits of taking this medication.
