Clomiphene

Product Introduction (Clomiphene Citrate)

Clomiphene Citrate is an oral medication that aims at solving some female infertility issues. It stimulates the secretion of follicle-stimulating hormone (FSH), which triggers the ovary to produce one or more egg follicles.

Clomiphene citrate, commonly sold under the brand names Clomid and Serophene, has been a cornerstone in treating female infertility for the past 40 years. It can effectively stimulate ovulation and is preferred by many since it is easy to use and rare side effects are associated with it. Recently letrozole an aromatase inhibitor noted increased live births in women with PCOS and often prescribed as first-line treatment for anovulatory women with PCOS.

How Clomiphene Works

Clomiphene is a selective estrogen receptor modulator (SERM) that works by reducing estrogen's effects in the body, thereby stimulating the release of hormones necessary for ovulation. It contains two isomers: Zu-clomiphene and en-clomiphene, where en-clomiphene is more active and plays the major role in the stimulation of follicular development. It is metabolized in the liver and is eliminated through the rectum.

Dosage Information

Initial Dosage: The recommended dosage is 50 mg for the first five days of the cycle starting from the fifth day of menstruation. This dose can be increased or decreased depending on the patient's response to treatment.

Missed Dose: In case, a dose is forgotten, the patient should take it whenever he remembers the necessity unless it is the time for the next dose. Do not double the dose to make up for the missed one.

Overdose: In case of overdose, seek immediate medical attention. Symptoms may include nausea, vomiting, blurred vision, and abdominal discomfort.

Monitoring and Adjustments: It is important to have periodical medical checkups. If the first dose does not have any effect, the healthcare provider may adjust it in the subsequent cycles in steps depending on the patient’s condition.

Cycle Limitations: Treatment is often limited to about 3-6 cycles because of negative outcomes linked to increased dosage and treatment period.
