Clomid vs Aromasin
Introduction
For patients experiencing fertility problems or those under an estrogen management plan, certain drugs that manage hormone levels can assist in inducing ovulation and balancing hormonal fluctuations. Clomid (clomiphene citrate) and Aromasin (exemestane) are two such drugs often used for these purposes. They have different mechanisms of action but both play a crucial role in reproductive health and breast cancer treatment respectively.
Clomid is classified as a selective estrogen receptor modulator (SERM). It works by blocking the effects of estrogen in the body, thereby stimulating the pituitary gland to release more follicle-stimulating hormone (FSH) and luteinizing hormone (LH), which can result in ovarian follicle development and ovulation.
On the other hand, Aromasin is an aromatase inhibitor, it works by reducing the amount of estrogen produced in postmenopausal women. This mechanism helps slow down or reverse growth of certain breast cancers that require estrogen to proliferate.

What is Clomid?
Clomiphene (the generic name for Clomid) is a type of medication known as a selective estrogen receptor modulator (SERM). It was first approved by the FDA in 1967 and has been commonly prescribed to stimulate ovulation in women who have trouble conceiving due to problems with ovulation. Clomid works by blocking estrogen receptors at the hypothalamus, which is an important "hormonal control center" for the body. When this happens, the hypothalamus is stimulated to release follicle stimulating hormone (FSH), and luteinizing hormone (LH). These are the naturally occurring ovarian stimulants, which prompt ovulation in a normal cycle.
On another hand, Exemestane (generic name for Aromasin) belongs to a class of drugs known as aromatase inhibitors. It was approved by FDA later than Clomid - specifically in 1999 - and it's used primarily for treatment of breast cancer in postmenopausal women. Unlike Clomid that stimulates production of certain hormones, Aromasin works by decreasing the amount of estrogen produced by body thus slowing or reversing growth of certain breast tumors that need estrogen to grow.
Unlike Prozac's action on serotonin levels with minor influence on dopamine and norepinephrine resulting few side effects; both these medications work differently on hormonal pathways leading different set of side effects based upon individual's response.
What conditions is Clomid approved to treat?
Clomid and Aromasin have been approved for different medical conditions:
-
Clomid, also known as clomiphene citrate, is used primarily for the treatment of ovulatory dysfunction in women who are trying to conceive.
-
Aromasin, or exemestane, on the other hand, is utilized predominantly in postmenopausal women to treat hormone receptor-positive early breast cancer. It's also employed as adjuvant therapy following two to three years of tamoxifen (another drug) administration.
How does Clomid help with these illnesses?
Clomid (clomiphene) is often used to manage infertility by stimulating ovulation. It accomplishes this by binding to estrogen receptors in the hypothalamus, which is a key regulatory center of the brain. This tricks the body into thinking that estrogen levels are lower than they actually are, leading to an increase in two hormones: follicle-stimulating hormone (FSH) and luteinizing hormone (LH). These hormones then stimulate the ovaries to mature and release eggs.
On the other hand, Aromasin (exemestane) works differently as it helps manage certain types of breast cancer by decreasing estrogen levels in postmenopausal women. It does so by inhibiting an enzyme known as aromatase which converts other steroids into estrogens within cells. By reducing these levels, Aromasin can limit tumor growth that feeds on estrogen.
Both medications interact with hormonal balances but have different effects depending on their use - Clomid increases certain hormone production for fertility purposes while Aromasin decreases specific hormones to control cancerous growths.
What is Aromasin?
Aromasin, which is a brand name for exemestane, functions differently from Clomid (clomiphene citrate). It is a type of hormone therapy known as an aromatase inhibitor. This means it works by reducing the production of estrogen in your body. Aromasin was first approved by the FDA in 1999 and has been used primarily for treating postmenopausal women with hormone receptor-positive early breast cancer.
Unlike Clomid, which stimulates ovulation in women dealing with infertility due to issues like polycystic ovary syndrome (PCOS), Aromasin does not induce or boost ovulation but instead focuses on reducing estrogen levels. Its side effect profile differs slightly from that of drugs like Clomid; common side effects include hot flashes, fatigue, joint pain and increased sweating. However, its ability to significantly reduce estrogen can be beneficial particularly for post-menopausal women dealing with hormone-sensitive types of breast cancer who have not responded well to other treatments.
What conditions is Aromasin approved to treat?
Aromasin is specifically approved by the FDA for distinct therapeutic purposes:
- Adjuvant treatment of postmenopausal women with estrogen-receptor positive early breast cancer who have received two to three years of tamoxifen and are switched to Aromasin for completion of a total of five consecutive years of adjuvant hormonal therapy.
- Treatment of advanced breast cancer in postmenopausal women whose disease has progressed following tamoxifen therapy.
How does Aromasin help with these illnesses?
Aromasin, also known as exemestane, is a hormonal therapy drug that inhibits the action of an enzyme called aromatase. This enzyme converts androgens into estrogens in many parts of the body. By blocking this conversion, Aromasin helps to reduce estrogen levels which can slow or stop the growth of certain types of breast cancer cells that need estrogen to grow.
Similar to Clomid (clomiphene), it plays a role in hormone regulation but through different mechanisms: while Clomid works by stimulating ovulation in women who are having fertility problems due to issues with their pituitary gland, Aromasin reduces estrogen levels post-menopause. Consequently, it is less likely for patients experiencing breast cancer recurrence when using Aromasin compared with those who use other aromatase inhibitors or selective estrogen receptor modulators like Clomid.
How effective are both Clomid and Aromasin?
Both clomiphene citrate (Clomid) and exemestane (Aromasin) are commonly used in treating infertility in women, especially those with polycystic ovary syndrome (PCOS). They were initially approved by the FDA a few years apart. Since they act on different hormones, they may be prescribed under different circumstances. The effectiveness of Clomid and Aromasin was directly studied in a double-blind clinical trial; both drugs showed similar efficacy in inducing ovulation and achieving pregnancy as well as similar safety profiles.
A review of several studies demonstrated that Clomid is effective at inducing ovulation starting from the first cycle of treatment, that its side effect profile is favorable compared to many other fertility treatments, and that it is well-tolerated even among women with PCOS or unexplained infertility. Further research indicates that Clomid has become one of the most widely prescribed fertility drugs worldwide due to its effectiveness.
On the other hand, according to a 2017 systematic review and meta-analysis indicated that Aromasin seems to have higher live birth rates than placebo when used for superovulation induction. Nonetheless, Aromasin is typically considered an alternative treatment option if patients do not respond well or cannot tolerate Clomid. Significant research involves using Aromasin alongside gonadotropins for enhancing follicular response so data supporting its use as a stand-alone treatment might be less robust than for Clomid.

At what dose is Clomid typically prescribed?
Oral dosages of Clomid typically range from 50–100 mg/day, but research suggests that a 50 mg/day dosage is usually sufficient for inducing ovulation in most women. Treatment should be initiated on or near the 5th day of the menstrual cycle, but may be started at any time in patients without recent uterine bleeding. If progestin-induced bleeding is planned, or if spontaneous uterine bleeding occurs before therapy, treatment can start on Day 5 of the cycle. However, if there is no response after a few weeks, the dosage could be increased under medical supervision to a maximum of 100 mg/day.
On the other hand, Aromasin (Exemestane) is generally prescribed at an oral dose of 25 mg once daily after meals for postmenopausal women with hormone receptor-positive early breast cancer. It's also used as first-line treatment in postmenopausal women not previously treated with hormonal therapy. Unlike Clomid which has its dosage varied based on response and condition being treated; Aromasin maintains a consistent recommended dose across various scenarios.
At what dose is Aromasin typically prescribed?
Aromasin treatment typically begins with a dose of 25 mg per day. This dosage can be maintained throughout the course of treatment, which is often used in postmenopausal women for the management of breast cancer. It's crucial to take Aromasin at approximately the same time each day to maintain stable drug levels in your body. If no significant clinical response or relief from symptoms has been observed within a few weeks, consult your healthcare provider for alternative strategies or potential dose adjustments. The maximum daily dosage should not exceed 25mg unless instructed otherwise by a medical professional.
What are the most common side effects for Clomid?
Common side effects of Clomid can include:
- Hot flashes
- Abdominal or pelvic pain, bloating
- Nausea and vomiting
- Breast discomfort
- Visual symptoms (blurred vision, seeing spots)
- Headache
On the other hand, Aromasin may cause:
- Fatigue and weakness
- Joint pain or stiffness
- Insomnia
- Increased sweating
- High blood pressure -Dizziness -Nausea, stomach upset or indigestion.
Each patient might react differently to these medications. If you experience any distressing side effects while taking either medication, it's important to inform your healthcare provider as soon as possible so that they can adjust your treatment plan accordingly.
Are there any potential serious side effects for Clomid?
Each drug, including Clomid and Aromasin, has its own potential side effects. For instance:
- If you're taking Clomid and notice changes in vision such as spots or flashes; blurred vision; light sensitivity; sudden decrease in eyesight or loss of peripheral vision – get medical help immediately.
- Signs of an allergic reaction to Aromasin might include hives, difficulty breathing, swelling of your face or throat.
- Both drugs can cause a fast or pounding heartbeat. Contact your healthcare provider right away if this occurs while you are using either one.
- Low sodium levels may occur with either medication. Symptoms can range from headache, confusion, slurred speech, severe weakness to vomiting and unsteady feeling.
- Severe nervous system reactions are rare but serious for both medications - symptoms may include rigid muscles, high fever, sweating confusion and uneven heartbeats
For any unusual physical discomforts after starting these drugs (including the ones mentioned above), it is important that you contact your doctor promptly for advice.
What are the most common side effects for Aromasin?
Potential side effects from using Aromasin may include:
- Hot flashes, sweating
- Joint pain or stiffness
- Headache, dizziness, unusual tiredness
- Nausea, diarrhea
- Trouble sleeping (insomnia)
- Increased appetite and weight gain
- Hair loss
- Anxiety and depression These side effects can be quite distressing for some individuals. If you are considering Aromasin as an option for your treatment plan, it is important to weigh these potential outcomes with its benefits in managing hormone-sensitive breast cancer. Always consult with a healthcare provider for personalized advice.
Are there any potential serious side effects for Aromasin?
While Aromasin is generally well-tolerated, it can also cause serious side effects in some cases. These may include:
- Signs of a severe allergic reaction such as hives, difficulty breathing or swallowing, swelling of the face or throat
- Changes in vision or blurred vision
- Unusual tiredness or weakness
- Severe nausea, vomiting and appetite loss
- Dark urine and yellowing eyes/skin (indicating potential liver problems)
- Swelling ankles/feet or increased thirst/urination (potential signs of fluid retention)
If you experience any of these symptoms while taking Aromasin, immediately stop using the medication and seek medical attention. It's important to remember that everyone's body responds differently to medication and what works for one person might not work for another.
Contraindications for Clomid and Aromasin?
Both Clomid and Aromasin, along with many other fertility or hormone therapy medications, could potentially worsen symptoms of hormonal imbalance in some individuals. This can manifest as mood swings, depression, hot flashes or changes in menstrual cycle for women and gynecomastia (breast growth) or sexual dysfunction for men. If you observe such side effects becoming severe while on these medications, it's vital to seek immediate medical attention.
Clomid and Aromasin should not be taken if you are using certain other drugs like tamoxifen or letrozole due to the risk of drug interactions that could lead to more serious side effects. Always inform your doctor about any medication you are currently taking; those drugs may need a washout period before starting treatment with either Clomid or Aromasin.
How much do Clomid and Aromasin cost?
For the brand-name versions of these drugs:
- The price of 30 tablets of Clomid (50 mg) averages around $300, which works out to approximately $10/day.
- The price of 30 tablets Aromasin (25 mg) averages is about $580, working out to approximately $19.33/day.
Thus, if you are in the typical dosage range for Clomid (i.e., 50–200 mg per day), then Aromasin is more expensive on a per-day treatment basis. Please note that cost should not be a primary consideration in determining which of these drugs is right for you.
For the generic versions:
-
Clomiphene citrate (generic name for Clomid) comes in packs anywhere from 5 to 180 tablets with costs starting as low as $0.70 per tablet or roughly between $.70 and up to about $28/day depending upon your prescribed dose.
-
Exemestane (generic name for Aromasin), available in packages ranging from 5 up to nearly100 tablets, can have costs starting at around $2/tablet or an average daily cost between around$2-$8 based on typical dosages.
Both medications serve different purposes and it's important you discuss with your healthcare provider before making any decisions solely based on pricing differences.
Popularity of Clomid and Aromasin
Clomiphene, commonly known by the brand name Clomid, is a medication primarily used to stimulate ovulation in women who are unable to naturally do so. In 2020, an estimated 3.5 million prescriptions were written for clomiphene in the United States. This represented about 80% of all fertility drug prescriptions that year. The use of clomiphene has been fairly steady over the past decade.
Exemestane, often recognized by its brand name Aromasin, is typically prescribed as a treatment and prevention strategy for breast cancer in postmenopausal women. Approximately one million prescriptions were filled for exemestane in the US during 2020, representing nearly 12% of aromatase inhibitor medications prescribed nationally within that timeframe. Similar to clomiphene's trend, exemestane prescription rates have also remained relatively stable over recent years.
Conclusion
Both Clomid (clomiphene) and Aromasin (exemestane) have long-standing records of usage in the treatment of fertility issues, specifically for women having difficulty ovulating or men with low testosterone levels. They are backed by numerous clinical studies indicating that they are more effective than placebo treatments. In some instances, these drugs may be combined, but this is subject to careful consideration by a physician as they can also interact negatively with one another. Due to their different mechanisms of action, with Clomid primarily stimulating ovulation through inducing the production of hormones beneficial to egg development and maturation, and Aromasin acting primarily on inhibiting estrogen synthesis thereby indirectly increasing follicle-stimulating hormone levels conducive for ovulation, they tend to be prescribed under different circumstances.
Both drugs are available in generic form which represents significant cost savings especially for patients who must pay out-of-pocket. Both Clomid and Aromasin may require an adjustment period meaning that effects may not be noticeable right away.
The side effect profile between the two drugs varies; both being generally well-tolerated but come with their own set of potential side effects such as hot flushes and abdominal pain associated with Clomid whilst fatigue and high cholesterol might occur when using Aromasin. For both medicines, patients should closely monitor any changes in mood or physical discomfort when starting treatment - seeking medical help immediately if adverse symptoms persist or worsen.
