Gonal F vs Clomid
Introduction
For patients dealing with infertility or other issues related to ovulation, certain drugs that manage the hormones involved in reproductive health can aid in stimulating ovulation and increasing fertility. Gonal F and Clomid are two such medications often prescribed for these conditions. They each impact different aspects of hormonal balance but both aim at enhancing female fertility.
Gonal F is a follicle-stimulating hormone (FSH) which primarily works by encouraging the ovaries to produce more eggs during the menstrual cycle. It's usually administered as injections under close monitoring from healthcare professionals due to its powerful effect and potential side effects.
On the other hand, Clomid or clomiphene citrate acts by blocking estrogen receptors in the brain. This creates a perceived low level of estrogen which subsequently prompts an increased production of follicle-stimulating hormone (FSH) and luteinizing hormone (LH). These hormones then stimulate more robust ovulation.
What is Gonal F?
Follitropin alfa (the generic name for Gonal F) was a significant advancement in the class of fertility drugs known as gonadotropins, which represented a major progression from the first class of fertility drugs such as clomiphene citrate (Clomid). Follitropin alfa was first approved by the FDA in 1995. Gonal F stimulates the ovaries to produce eggs and thus is used to treat infertility in women who cannot ovulate and do not have primary ovarian failure. It works by directly stimulating the follicles and supporting their growth in the ovaries, thereby increasing levels of estradiol. On the other hand, Clomid works indirectly by stimulating an increase in hormones that support follicular stimulation and growth. As Gonal F has a more targeted effect on ovarian stimulation compared with Clomid, it tends to result in fewer side effects related to systemic hormonal fluctuations.
What conditions is Gonal F approved to treat?
Gonal F is approved for the treatment of various fertility issues such as:
- Anovulation, including polycystic ovary syndrome (PCOS), in women who have failed to respond to other treatments like clomiphene citrate
- Stimulation of follicle development in women undergoing assisted reproductive technologies (ART) procedures, such as in vitro fertilization (IVF)
- Hypogonadotropic hypogonadism and cryptorchidism in men when used alongside human chorionic gonadotropin.
How does Gonal F help with these illnesses?
Gonal F aids in managing infertility by stimulating the ovaries to produce mature eggs. It works by mimicking the natural follicle-stimulating hormone (FSH), a crucial component for ovarian follicular growth and maturation. This medication is administered through injections, allowing it to directly stimulate the development of one or more follicles, which can then release an egg during ovulation. On the other hand, Clomid stimulates ovulation indirectly by encouraging the pituitary gland to secrete more FSH and luteinizing hormones (LH). These hormones are essential in triggering ovulation and preparing the body for pregnancy. However, unlike Gonal F that acts directly on ovaries, Clomid's indirect mechanism may lead to multiple egg releases resulting in higher chances of twins or multiple pregnancies.
What is Clomid?
Clomid is a brand name for clomiphene, an oral medication used to stimulate ovulation. Clomiphene belongs to the group of medicines known as selective estrogen receptor modulators (SERMs). It works by binding to estrogen receptors in the hypothalamus and blocking their normal feedback mechanism. This leads to an increase in the production of gonadotropins, hormones that stimulate the ovaries to release eggs. First approved by FDA in 1967, Clomid has been one of the most commonly prescribed fertility drugs.
Unlike Gonal F, which is an injectable form of follicle-stimulating hormone (FSH), Clomid does not directly stimulate follicles but rather triggers your body's natural system. Its side-effect profile also differs from that of Gonal F; it may cause hot flashes, breast tenderness, nausea and mood swings among other symptoms whereas Gonal F can lead more often to ovarian hyperstimulation syndrome or multiple pregnancies due its direct stimulating effect on ovaries.
Clomid's method of action can be beneficial for treating infertility especially in patients who have polycystic ovary syndrome (PCOS) or other issues with ovulatory function.
What conditions is Clomid approved to treat?
Clomid, also known as clomiphene, is a medication that the FDA has approved for use in the treatment of:
- Anovulation or oligo-ovulation (absent ovulation cycles or few ovulation cycles)
- Polycystic Ovary Syndrome (PCOS), which can cause fertility issues in women
- Other unexplained infertility cases where stimulating and regulating ovulation could increase chances of conception.
How does Clomid help with these illnesses?
Clomiphene Citrate, more commonly known as Clomid, is a drug that plays an essential role in fertility treatment. It works much like a hormone by stimulating the pituitary gland to release follicle-stimulating hormones (FSH) and luteinizing hormones (LH). These two hormones are critical for ovulation - the process where an egg matures and gets released from the ovaries. In contrast to Gonal F, which directly introduces FSH into the body, Clomid encourages natural production of these vital hormones. This indirect mechanism provides a more balanced hormonal environment conducive to pregnancy. For women who have issues with ovulation or those diagnosed with polycystic ovarian syndrome (PCOS), Clomid can be particularly beneficial in enhancing their chances of conception when other treatments may not work as effectively.
How effective are both Gonal F and Clomid?
Gonal F and Clomid are both commonly used medications in the treatment of infertility, with different mechanisms of action. Gonal F is a form of follicle-stimulating hormone (FSH), which stimulates the ovaries to produce more eggs, while Clomid works indirectly by stimulating the pituitary gland to produce more FSH.
The effectiveness of Gonal F and Clomid in inducing ovulation was studied extensively; both drugs showed similar efficacy in promoting egg production but have different safety profiles. In one study, none of the various measures used to assess success rates differed significantly between patients receiving Gonal F or those given Clomid. However, it was noted that women taking Gonal F were somewhat less likely than those on Clomid to experience side effects such as hot flashes and mood swings.
A 2006 review demonstrated that from the first cycle of treatment, both drugs effectively stimulate ovulation and increase pregnancy chances compared with placebo. Furthermore, they are well-tolerated among most women seeking fertility treatments. The same study reports that although Clomid has been around longer and thus prescribed widely across the world for its oral administration advantage over injectable forms like Gonal-F.
A 2013 meta-analysis indicated that though there's no significant difference between these two drugs' overall effectiveness at inducing ovulation or resulting pregnancies per cycle initiated, individual patient characteristics might make one drug more favorable over another. For instance, patients who may not respond well enough due to polycystic ovarian syndrome (PCOS) could benefit from switching from clomiphene citrate (Clomid) to gonadotropins such as follitropin alfa (Gonal-F). Nonetheless, due to their unique modes of action - direct ovarian stimulation using Gonadotropins versus indirect pituitary stimulation via clomiphene citrate may be beneficial depending upon individual response patterns & associated factors like age or underlying cause for anovulation.
At what dose is Gonal F typically prescribed?
Injectable dosages of Gonal F for women undergoing ovulation induction typically range from 75–300 IU/day, but studies have shown that starting at 75 IU/day is usually sufficient. Dosage can be increased after a week if there is no adequate response in ovarian follicular growth and/or serum estradiol levels. The maximum dosage that should not be exceeded in any case is 450 IU/day. For Clomid, the oral dosage generally starts at 50 mg/day for five days, and may increase to up to 150 mg/day if ovulation does not occur. Always consult with your healthcare provider for personalized medication advice.

At what dose is Clomid typically prescribed?
Clomid treatment is typically initiated at a dosage of 50 mg/day for five days early in the menstrual cycle, often starting on the third day. If there's no response (an ovulatory menstrual cycle isn't achieved), the dose can be increased to 100 mg/day for another five-day course in the next cycle. The maximum recommended dose is 150 mg/day for five days, which may be attempted if lower dosages are ineffective over three cycles. This approach should only be taken under close medical supervision due to potential side effects and risks associated with higher doses and longer treatment durations.

Are there any potential serious side effects for Clomid?
While Clomid is generally well tolerated, it's important to be aware of potential side effects. These may include:
- Allergic reactions such as rash, itching, hives and swelling of the lips or face
- Visual disturbances including blurred vision or seeing spots or flashes (scintillating scotomata). If you experience visual problems while taking Clomid, contact your doctor immediately.
- Abnormal uterine bleeding
- Stomach discomfort
- Ovarian hyperstimulation syndrome (OHSS), a potentially serious condition marked by enlarged ovaries filled with fluid. Symptoms can include abdominal pain and swelling, nausea, vomiting and weight gain.
If any of these symptoms occur while you're using Clomid, seek immediate medical attention. It’s crucial that any unusual symptoms are checked out promptly to ensure safe treatment.
Contraindications for Gonal F and Clomid?
Both Gonal F and Clomid, along with other fertility medications, may cause side effects in some people. If you experience severe abdominal pain, bloating, nausea or vomiting while using these medications, it's important to seek immediate medical attention.
Gonal F and Clomid should not be used if you have certain health conditions such as an uncontrolled thyroid disorder or adrenal gland disorder; ovarian cysts (not caused by polycystic ovary syndrome); abnormal vaginal bleeding; liver disease; pregnancy-related issues like the presence of a uterine fibroid or tumor. Always inform your physician about your current health status before starting treatment.
Also remember that both Gonal F and Clomid can interact with other drugs including hormonal therapies and certain over-the-counter supplements. It’s essential to tell your doctor about any medication you are currently taking before beginning treatment with either drug.
How much do Gonal F and Clomid cost?
For the brand name versions of these fertility drugs:
- The price for one Gonal F pen (450 IU) averages around $330, which works out to approximately $83 per day for a typical dose of 150 IU/day.
- The price of 5 tablets of Clomid (50 mg) is about $30, working out to approximately $6/day.
Thus, if you are taking the lower dosage range for Gonal F (i.e., 75 IU/day), then brand-name Clomid is less expensive on a per-day treatment basis. However, cost should not be your primary consideration in determining which drug is right for you as they have different indications and side effects.
Clomiphene citrate is the generic version of Clomid and costs significantly less than its branded counterpart:
- Clomiphene citrate (50 mg tablets) comes in packs ranging from 5 to 180 tablets with approximate costs starting at $9 for five days' supply or about $1.80 per day.
There's currently no generic version available for Gonal F in the United States. This can contribute to it being more expensive compared to other fertility treatments such as clomiphene citrate. As always, prices may vary depending on insurance coverage and pharmacy locations.
Popularity of Gonal F and Clomid
Gonal F, a brand name for Follitropin Alfa which is an injectable form of the follicle stimulating hormone (FSH), is prescribed to stimulate egg production in women who wish to become pregnant. In 2020, Gonal F was estimated to have been prescribed about 250,000 times in the United States.
Clomiphene Citrate, also known by its brand name Clomid, is another fertility medication that works differently. It stimulates ovulation by inhibiting estrogen receptors at the hypothalamus. This prompts increased release of gonadotropins and can result in multiple eggs being released during one menstrual cycle. Clomid was prescribed approximately 1 million times across America in 2020.
Both medications are commonly used as part of assisted reproductive treatments like IVF (In-Vitro-Fertilization). The choice between these two largely depends on a woman's specific situation and her doctor’s recommendation based on individual hormonal levels and other health factors.
Conclusion
Both Gonal F (follitropin alfa) and Clomid (clomiphene citrate) are popularly used in fertility treatments, with a wealth of clinical studies supporting their efficacy. Occasionally, these drugs may be used together as part of an assisted reproductive technology regime. However, it's important to note that the two medications work via completely different mechanisms: Gonal F is a follicle-stimulating hormone (FSH) preparation which directly stimulates egg development in the ovaries, while Clomid works by tricking the body into producing more follicle stimulating hormone and luteinizing hormone.
Clomid is typically regarded as first-line treatment due to its oral administration and lower cost. It is generally effective in inducing ovulation but can sometimes lead to thinning of the endometrial lining or cervical mucus changes - factors that could potentially hinder conception.
On the other hand, Gonal F requires injection but offers greater control over ovarian stimulation and reduced risk of multiple pregnancies compared to Clomid. It's often chosen when patients haven't responded well to initial therapy with clomiphene or have certain conditions like Polycystic ovarian syndrome (PCOS).
Side effects from both drugs are usually mild though some individuals may be prone to experiencing headaches, mood swings or bloating with either drug. With more potent effects on ovaries than Clomid, there’s also added risk for Ovarian Hyperstimulation Syndrome (OHSS) with Gonal-F. As always patients should pay close attention to how they're feeling during any fertility treatment course and consult healthcare professionals promptly if they experience unusual discomforts.
