Urofollitropin
Before using Urofollitropin, it is essential for patients to consult with their healthcare provider to ensure the medication is appropriate for their condition. Some key precautions include:
- Ovarian Hyperstimulation Syndrome (OHSS): Urofollitropin is associated with an increased risk of ovarian hyperstimulation syndrome (OHSS), a potentially serious condition that can cause swollen, painful ovaries and other complications. Patients should be monitored for signs of OHSS, particularly in the early stages of treatment.
- Multiple Pregnancies: Urofollitropin increases the chances of multiple pregnancies (e.g., twins, triplets), which may carry additional risks for both the mother and babies. Women undergoing fertility treatment should be aware of this possibility and discuss it with their healthcare provider.
- Pre-existing Ovarian Conditions: Urofollitropin should be used cautiously in patients with ovarian cysts, ovarian failure, or other ovarian conditions. It may not be effective in patients with diminished ovarian reserve.
- Pregnancy and Lactation: Urofollitropin is typically not recommended during pregnancy, as its safety has not been fully established in pregnant women. Additionally, it is unclear whether urofollitropin is excreted in breast milk, so it should be used with caution in breastfeeding women.
- Hypersensitivity Reactions: Some patients may experience allergic reactions to urofollitropin. Signs of a serious reaction may include hives, difficulty breathing, or swelling of the face or throat, requiring immediate medical attention.
- Thromboembolic Events: There is an increased risk of blood clots and thromboembolic events (e.g., stroke, heart attack) associated with the use of fertility medications like urofollitropin, especially in women with certain predisposing risk factors (e.g., obesity, smoking, or age >35).
Urofollitropin is primarily used for assisted reproductive technology (ART) in women who are undergoing fertility treatments. It is used to promote the development of multiple follicles in women undergoing in vitro fertilization (IVF) or ovarian stimulation for other ART procedures. Urofollitropin is an FSH (follicle-stimulating hormone) preparation that helps stimulate the ovaries to produce multiple eggs.
Key indications include:
- In vitro fertilization (IVF): Used to stimulate the ovaries in preparation for egg retrieval in IVF.
- Ovarian Stimulation: Used to treat infertility in women with anovulation or oligoovulation (irregular ovulation) who require ovulation induction to improve the chances of conception.
- Controlled Ovarian Hyperstimulation (COH): It is used as part of a COH regimen to increase the number of follicles produced by the ovaries, thereby increasing the number of mature eggs available for fertilization.
There are certain conditions where urofollitropin should not be used, as it may worsen underlying health issues or not be effective:
- Pregnancy: Urofollitropin is contraindicated during pregnancy, as it is a fertility stimulant and could potentially harm the fetus.
- Ovarian Cysts: Urofollitropin should not be used in women with non-functional ovarian cysts, ovarian failure, or premature ovarian failure, as the ovaries may not respond to the medication.
- Uncontrolled Thyroid or Adrenal Disorders: Women with uncontrolled thyroid disease or adrenal disorders should not use urofollitropin, as it can complicate hormone regulation.
- Pituitary or Hypothalamic Disorders: Women with pituitary or hypothalamic dysfunction (e.g., low levels of LH and FSH due to pituitary insufficiency) may not respond adequately to urofollitropin.
- Prior Allergic Reactions: Patients with known hypersensitivity to urofollitropin or its components (e.g., human menopausal gonadotropin (hMG) or other ingredients) should avoid this medication.
Common side effects associated with urofollitropin may include:
- Ovarian Hyperstimulation Syndrome (OHSS): This is the most serious side effect, characterized by swollen, painful ovaries, bloating, and fluid buildup in the abdomen. Symptoms of OHSS include nausea, vomiting, shortness of breath, and weight gain.
- Multiple Pregnancies: There is an increased risk of multiple pregnancies, which can result in complications for both the mother and babies.
- Headaches: Some women experience headaches during treatment, likely due to hormonal changes.
- Mood Changes: Hormonal fluctuations during treatment may lead to mood swings or irritability.
- Injection Site Reactions: Common reactions include redness, pain, or swelling at the site of injection.
- Abdominal Pain or Discomfort: Some women may experience abdominal bloating, discomfort, or mild cramping.
- Nausea or Vomiting: These symptoms may occur due to the stimulation of the ovaries or as part of the body's response to the fertility treatment.
Severe side effects, though rare, include severe OHSS, blood clots, stroke, and cardiovascular events.
Patients should immediately report symptoms such as severe abdominal pain, nausea, vomiting, or breathing difficulties, as they may indicate OHSS or other complications.

Urofollitropin is a gonadotropin, specifically FSH (follicle-stimulating hormone), which plays a key role in the reproductive system. It is used to stimulate the ovaries to develop multiple follicles during ovulation induction for fertility treatments. The mechanism of action includes:
- Follicle Development: Urofollitropin mimics the action of the body's natural FSH, which stimulates the ovaries to produce eggs (oocytes). It encourages the growth and maturation of ovarian follicles, improving the chances of successful ovulation and fertilization.
- Controlled Ovulation: In fertility treatments, urofollitropin is used to stimulate multiple follicles, leading to a higher chance of obtaining multiple mature eggs for IVF or other reproductive procedures.
- Hormonal Regulation: Urofollitropin is used in conjunction with other hormones like human chorionic gonadotropin (hCG) to trigger ovulation once the follicles have matured.
Urofollitropin may interact with other medications, particularly those that affect hormone levels or reproductive functions:
- Gonadotropin-Releasing Hormone (GnRH) Agonists and Antagonists: When used together, GnRH agonists and GnRH antagonists can alter the efficacy of urofollitropin. These medications work to control the release of gonadotropins, and their combined use requires careful monitoring and dose adjustment.
- Corticosteroids: Systemic corticosteroids used for treating inflammation or autoimmune conditions may interfere with the effectiveness of fertility treatments, though the interaction with urofollitropin is less direct.
- Other Ovarian Stimulants: When combined with other ovarian stimulants (e.g., clomiphene citrate or hCG), the risk of OHSS or multiple pregnancies is heightened, requiring careful management by a fertility specialist.
- Thyroid Hormones: Hypothyroidism or hyperthyroidism can interfere with fertility treatments. If thyroid function is not well-controlled, it may affect the response to urofollitropin.
Patients should always inform their healthcare provider about any medications, supplements, or over-the-counter products they are taking to avoid potential drug interactions.
The typical starting dose for urofollitropin in fertility treatments is based on the specific needs of the patient, but common dosing guidelines are:
- Starting Dose: 75-150 IU of urofollitropin per day, typically administered via subcutaneous injection.
- Dose Adjustment: Depending on the patient's response, the dose may be adjusted upwards or downwards during the stimulation cycle.
- Maximum Dose: The dose may be increased up to 225 IU per day, depending on the individual's ovarian response and the guidance of the fertility specialist.
It is important that the dosing regimen be carefully tailored by a healthcare provider to optimize results and minimize risks like OHSS.
Urofollitropin is not typically used in children, as it is specifically indicated for female infertility treatment in adults. Use in pediatric patients is considered off-label and should be carefully evaluated by a pediatric endocrinologist or fertility specialist. The medication is not indicated for use in male patients for conditions like hypogonadism or oligospermia.
As always, a healthcare provider should be consulted before starting urofollitropin to ensure its safety and efficacy for the patient's specific condition.
There is no specific dose adjustment required for patients with renal impairment when using urofollitropin. However, as urofollitropin is a recombinant hormone, systemic absorption is minimal when administered via subcutaneous injection. Patients with severe renal dysfunction should be closely monitored due to potential changes in hormonal levels, but urofollitropin is not typically contraindicated in such cases.
