When to Start Taking Clomid (Clomiphene Citrate)
Clomid (clomiphene citrate) should be started on or about the 5th day of the menstrual cycle if progestin-induced bleeding is planned or if spontaneous uterine bleeding occurs prior to therapy. 1
Timing of Clomid Administration
- For women with regular menstrual cycles, Clomid therapy should begin on approximately day 5 of the menstrual cycle (where day 1 is the first day of menstrual bleeding) 1
- For women with no recent uterine bleeding, Clomid can be started at any time, after pregnancy has been excluded 1
- The standard regimen is 50 mg daily for 5 days as the initial treatment course 1
Monitoring and Follow-Up
- Ovulation typically occurs 5-10 days after completing a course of Clomid 1
- Sexual intercourse should be timed to coincide with the expected time of ovulation 1
- Appropriate tests to determine ovulation may be useful during this time 1
- If ovulation does not occur after the first course, a second course of 100 mg daily for 5 days can be started as early as 30 days after the previous course, after excluding pregnancy 1
Important Considerations
- Before starting Clomid, a thorough diagnostic evaluation should be performed to identify any impediments to achieving pregnancy 1
- The therapeutic plan should be outlined in advance with the patient 1
- A low dosage is particularly recommended for patients with suspected sensitivity to pituitary gonadotropins, such as those with polycystic ovary syndrome, to reduce the risk of ovarian hyperstimulation syndrome 1
- Ultrasound monitoring during treatment is important to determine appropriate dosing for subsequent cycles and to minimize risks of hyperstimulation and multiple pregnancy 2
Duration of Treatment
- If ovulation occurs at the initial 50 mg dosage, there is no advantage to increasing the dose in subsequent cycles 1
- The majority of women who will respond to Clomid will do so after the first course of therapy 1
- If ovulation does not occur after three courses of therapy, further treatment with Clomid is not recommended, and the patient should be reevaluated 1
- If three ovulatory responses occur but pregnancy is not achieved, further treatment is not recommended 1
- Long-term cyclic therapy beyond a total of about six cycles is not recommended 1
- Some experts suggest that treatment could be extended to 12 cycles in responsive women before considering more complex methods of ovulation induction 2
Efficacy and Outcomes
- Clomid is the first-line treatment for normally estrogenized, anovulatory women 2
- The majority of women with "pure" anovulatory infertility respond to Clomid treatment 2
- Pregnancy and miscarriage rates with Clomid are close to those expected in a normal fertile population 2
- Increased body mass index is consistently associated with decreased response to Clomid, suggesting that weight reduction should be part of therapy in overweight anovulatory women 2
