Femara vs Tamoxifen

When it comes to breast cancer treatment, there are a few different options available. One of the most common treatments is chemotherapy, which can be done with Femara or tamoxifen. So, what’s the difference between Femara and tamoxifen? In this blog post, we will discuss the differences between Femara and tamoxifen, as well as their benefits and drawbacks.

What is Femara?

Femara is a type of medication known as a hormone antagonist. It works by blocking the effects of estrogen on breast cancer cells. Femara is most commonly used in post-menopausal women, as it can help reduce the risk of recurrence.

Benefits of Femara

disease free survival

Femara is a great option for women who are post-menopausal. It has been shown to decrease the risk of recurrence and metastasis in these patients. Femara can also be used as an adjuvant treatment, meaning that it should be used alongside other treatments like chemotherapy or radiation therapy. Femara helps prevent estrogen from attaching itself to breast cancer cells, thus slowing down their growth rate and preventing them from spreading throughout your body (metastasizing). This makes female more effective at preventing recurrences than tamoxifen alone would be on its own because female prevents estrogen from attaching itself which causes estrogen-sensitive cancers like invasive lobular carcinoma (ILC) or grade II & III ductal carcinoma in situ (DCIS) to have a better prognosis.

Side effects of Femara

Some side effects include nausea, fatigue, and joint pain. If you experience any of these symptoms while taking Femara, talk with your doctor immediately! They may want to adjust the dose or stop treatment altogether. Femara can also cause an increased risk for blood clots in women who have had breast cancer before (these are called post-menopausal women).

Serious side effects

Although uncommon, serious problems from Femara do occur. If you experience severe side effects, contact your doctor right away. If your symptoms appear to be life-threatening or if you believe you’re having a medical emergency, call 911.

The most common serious adverse effects are as follows:

Side effect details

You may be wondering how frequently certain adverse effects occur with this medication. Here’s a list of several of the side effects that this drug has.

Reduced bone mineral density

In some people, Femara decreases bone mineral density (weakened bones). Women who’ve gone through menopause are given Femara to lower their estrogen levels. Estrogen aids in the maintenance of healthy bones. However, after menopause, your estrogen levels decline, causing your bones to become weaker. Furthermore, because this medicine also lowers your estrogen level, the risk of injuring a bone is greater.

To discover how frequently this side effect was observed in clinical trials, consult the drug’s prescribing information.

If you’re on Femara, your doctor may want to measure your bone mineral density. This allows them to keep track of how strong your bones are. If your bones become weak as a result of therapy, your doctor may advise you to take medicine to help build up your bones. When taking Femara, there are several things you can do to support maintain the strength in your bones while minimizing loss of bone density.

If you’re unsure what Femara might do to your bone density, consult with your doctor.

Allergic reaction

Some people may experience an allergic reaction after taking Femara, just like with most medicines. It’s unclear how frequently this happens in women who take Femara.

Symptoms of a minor allergy reaction might include:

  • skin rash
  • itchiness
  • flushing (warmth and redness in your skin)

Although a rare occurrence, anaphylaxis is possible. Symptoms of anaphylactic shock include:

  • swelling under your skin, typically in your eyelids, lips, hands, or feet
  • swelling of your tongue, mouth, or throat
  • trouble breathing

If you have a severe allergic reaction to Femara, contact your doctor right away. If you think you’re having a medical emergency, call 911.

Fatigue or dizziness

Femara can cause tiredness (lack of energy) and dizziness in certain people. To learn how often these adverse effects occurred in clinical trials, consult the drug’s prescribing information.

Don’t drive or operate other machinery if you have tiredness or dizziness while taking Femara. Also, speak to your doctor about ways to help enhance your energy level during treatment.

Weight gain or weight loss

During treatment with Femara, your body weight may fluctuate. Both weight gain and reduction were noted in women who took Femara for cancer therapy during clinical trials.

Changes in appetite and weight are common side effects of both cancer and cancer therapies. If you’re concerned about your weight shifting while taking Femara, talk to your doctor.

Side effects after stopping Femara

clinical trial

There is no information about Femara stopping causing adverse effects. There’s also no need to taper down the dosage gradually.

If you’re not sure which dose is best for you, talk to your doctor about the risks and benefits of each. In certain circumstances, if Femara no longer works for you, your doctor may recommend that you cease taking it in order to induce a “withdrawal response.” This hormonal change occurs as a result of stopping Femara.

In this situation, stopping Femara might help your breast cancer instead of causing negative effects. However, this therapy technique isn’t suitable for everyone.

If your doctor recommends that you stop taking Femara, talk to them about whether stopping the treatment might be beneficial for you.

Off-label use of Femara for infertility

clinical trial

The Food and Drug Administration (FDA) has approved prescription drugs such as Femara to cure a variety of medical problems. However, because Femara is sometimes used off-label for a variety of purposes, it may also be prescribed for other issues. Off-label application refers to the use of a drug that has been authorized to treat one condition in treating another situation.

Femara is a medication that is off-label used to treat infertility in women. Ovulation difficulties (the release of eggs from your ovaries) are the most common reason for ovulation problems that lead to infertility. Polycystic ovarian syndrome (PCOS) is the most frequent cause of ovulation issues that result in infertility. *However, Femara can also be used to treat infertility without a clear cause.

In all of these situations, Femara is given to women in order to induce (cause) ovulation. To treat infertility using this approach, you’ll take Femara for a few days after your period begins. Your estrogen level will be temporarily reduced as a result of doing this.

The ovulation of your egg is induced by the presence of progesterone in your body. This causes the release of FSH and LH from your pituitary gland, which stimulates an egg in your ovary to mature and be released from it. Ovulation induction is a term used to describe this medication’s action.

If you take Femara before ovulation, more eggs will mature and be released from your ovaries than usual. This condition is known as superovulation or controlled ovarian hyperstimulation.

Effectiveness for infertility

Taking Femara can help you get pregnant if you’re trying to conceive (TTC) by way of sexual intercourse or intrauterine insemination (IUI). However, the success rates of Femara for achieving pregnancy or delivering live babies are influenced by a variety of factors. These factors include:

  • the cause of your infertility
  • your age
  • whether you’re using Femara with other fertility treatments

If your body isn’t already ovulating, you’re more likely to have success with Femara therapy for infertility.

See the drug’s prescribing information to learn how well Femara worked in clinical trials for infertility. If you have any questions or concerns about using Femara for infertility, see your doctor.

The American College of Obstetricians and Gynecologists (ACOG) endorses letrozole (the active component in Femara) as a successful therapy for producing ovulation.

Dosage for infertility

The usual dose of Femara for promoting ovulation is 2.5 mg taken by mouth once daily for 5 days. Your doctor may advise you to begin taking the medicine on day 3 or day 5 of your menstrual cycle, depending on whether you’re having periods when starting it. If you don’t have periods when starting Femara, your doctor will advise you as to when you should start treatment.

If you’re still having trouble getting your period, check with your doctor. If this is the case, it’s possible that you’ll need a higher dosage of Femara (5 mg or 7.5 mg daily for five days).

The highest dose of Femara for fertility treatment has not yet been determined. In 2011, research looked at using higher doses than the usual standard amount to treat infertility. However, more study is needed to see whether higher doses of Femara are more efficient than lower doses. Always follow your doctor’s instructions when taking Femara.

Side effects when using Femara for infertility

The following are some examples of adverse effects that can occur when taking Femara for infertility:

  • dizziness
  • fatigue (lack of energy)
  • hot flashes
  • breast tenderness
  • mood swings
  • night sweats
  • nausea
  • vomiting
  • spotting (light vaginal bleeding between periods)
  • ovarian cysts
  • rarely, ovarian hyperstimulation syndrome (OHSS), which is when more eggs than usual develop in your ovaries

How to take Femara for infertility

You’ll take Femara once a day for 5 days in a row after the start of your menstrual cycle. Your doctor may advise you to take Femara on either cycle days 3 to 7 or 5 to 9. (The first day of your menstrual cycle is considered Day 1.) Always follow your doctor’s instructions when taking Femara.

Ovulation generally happens between 5 and 10 days after your final Femara tablet has been taken. To assist you to determine when you’re about to ovulate, your doctor will usually recommend utilizing an ovulation predictor test.

If you’re trying to conceive (TTC) naturally, your doctor will also tell you when you should start having sex. If you’re using IUI, your physician will recommend when you should visit the clinic for artificial insemination.

What’s the best time of day to take Femara for infertility?

You may take Femara at any time of day. However, try to take it at the same time on each of the five days you’re taking the medicine.

How long can you take Femara for fertility treatment?

The maximum number of cycles that a doctor will prescribe Femara is six. This is because if you haven’t gotten pregnant after six treatment cycles, it’s unlikely that this medication will help you. If you’ve tried Femara and still haven’t been able to get pregnant, speak with your doctor about alternative infertility treatments.

Alternatives for infertility

Infertility may be treated with a variety of medications. Some medicines, such as choriogonadotropin alfa (Ovidrel), are used to cause ovulation (just like Femara). Other medicines, like progesterone (Prometrium), promote menstruation (periods). There are other drugs available that are used to cure infertility and perform various functions in the body.

If you’d like to learn more about infertility treatment alternatives, speak with your doctor.

What is Tamoxifen?
