What the FDA label approves clomiphene for
Clomiphene citrate is an oral ovulatory stimulant sold as a 50 mg tablet. Its prescribing information gives one indication: the treatment of ovulatory dysfunction in women desiring pregnancy. The same paragraph adds the condition that matters most for anyone shopping online: impediments to pregnancy must be excluded or adequately treated before the first course.
The label names the patients most likely to succeed: women with polycystic ovary syndrome (PCOS), amenorrhea-galactorrhea syndrome, psychogenic amenorrhea, post-oral-contraceptive amenorrhea and some cases of secondary amenorrhea of unknown cause. It also states what clomiphene is not for:
- Male infertility. The label says there are no adequate or well-controlled studies showing it works for men.
- Combined regimens with other ovulation drugs, and egg production for IVF. The label says there is no standard regimen for either and does not recommend these uses.
- Long courses. Cyclic therapy beyond a total of about six cycles is not recommended.
Why the label puts a workup before the first tablet
Clomiphene can only help when the problem is ovulation. The label restricts it to patients with demonstrated ovulatory dysfunction who meet these conditions, and asks for more checks on top:
| The label requires | What it means in practice |
|---|---|
| Not pregnant | Pregnancy ruled out before each course |
| No ovarian cysts or enlargement, except from PCOS | A pelvic examination before the first course and each later one |
| No abnormal vaginal bleeding | Unexplained bleeding is evaluated first, to rule out a tumor |
| Normal liver function | Liver disease or past liver dysfunction is a contraindication |
| Other impediments considered | Thyroid and adrenal disorders, high prolactin and male factor infertility |
| Triglycerides checked | Pretreatment screening is recommended because of reports of high triglycerides |
ASRM's committee opinion on evaluating infertile women goes further for couples: when a male partner is involved, both partners should be evaluated at the same time, with at least one semen analysis at the start, because a male factor is common. A form that asks three questions and ships a bottle cannot do any of this.
In Gala Fertility, the workup comes first: her bloodwork at a Quest lab, a pelvic ultrasound near you, and his semen analysis with a kit sent home. A clinician reads them together before any prescription.
Clomid dosage, as the label sets it
| Step | Clomiphene label |
|---|---|
| First course | 50 mg (one tablet) a day for 5 days |
| When to start | On or about day 5 of the cycle after a period or a progestin-induced bleed; at any time if there has been no recent bleeding |
| If she ovulates | No advantage to raising the dose in later cycles |
| If she does not ovulate | 100 mg a day for 5 days, as early as 30 days after the last course, once pregnancy is ruled out |
| Ceiling | More than 100 mg a day or longer than 5 days is not recommended |
| When to stop | After three courses without ovulation, or three ovulatory cycles without pregnancy: reevaluate |
The label adds that women with PCOS can be unusually sensitive and should start on the lowest dose and shortest course, and that most women who will ovulate on clomiphene do so after the first course.
Between cycles, the label asks for a check that she is not pregnant and has no ovarian enlargement or new cyst before the next course. In Gala Fertility, a cycle on letrozole or clomiphene is one tablet a day for 5 days, on days 3 to 7, prescribed one month at a time, with a check-in after every cycle. Your clinician sets the dose.
The risks: twins, OHSS and vision changes
- Multiple pregnancy. In the label's clinical trials, 7.98% of pregnancies were multiples: 6.9% twins, 0.5% triplets, 0.3% quadruplets and 0.1% quintuplets. The 2023 International PCOS Guideline notes that clomiphene cycles may need ultrasound monitoring for this reason.
- Ovarian hyperstimulation syndrome (OHSS). It can progress within 24 hours to several days and become serious. Early warning signs are abdominal pain and swelling, nausea, vomiting, diarrhea and weight gain. Tell your clinician the same day.
- Visual symptoms. Blurring, spots or flashes can occur, more often with higher total doses or longer use. They usually resolve, but the label reports prolonged and possibly irreversible cases. Anyone with visual symptoms should stop and have a full eye exam, and take care driving in changing light.
- Ovarian tumors with prolonged use. The label says epidemiology data suggest prolonged use may increase the risk of a borderline or invasive ovarian tumor, one more reason for the six-cycle ceiling.
The label's trial data put the more common side effects at these rates:
| Side effect | Share of patients in clinical studies |
|---|---|
| Ovarian enlargement | 13.6% |
| Hot flushes | 10.4% |
| Abdominal or pelvic discomfort, bloating | 5.5% |
| Nausea and vomiting | 2.2% |
| Breast discomfort | 2.1% |
| Visual symptoms | 1.5% |
| Headache | 1.3% |
| Abnormal uterine bleeding | 1.3% |
On miscarriage and birth defects, the label tells patients that available data suggest no increase compared with the general population.
Who should not take clomiphene
The label contraindicates it in pregnancy, in liver disease or a history of liver dysfunction, with abnormal uterine bleeding of undetermined origin, with ovarian cysts or enlargement not due to PCOS, with uncontrolled thyroid or adrenal dysfunction, with an organic intracranial lesion such as a pituitary tumor, and with an allergy to the drug. It also advises caution with uterine fibroids, which may enlarge.
Clomid or letrozole?
Clomiphene is the one FDA-approved pill for ovulation induction; letrozole is approved for breast cancer and used off-label. For women with PCOS who do not ovulate and have no other infertility factor, the 2023 International PCOS Guideline recommends letrozole over clomiphene, based on higher ovulation, pregnancy and live birth rates. It also says clomiphene can be used in preference to metformin alone, and that adding metformin to clomiphene could improve ovulation and pregnancy rates.
Which one fits depends on the workup, her history and anything she has already tried. Compare the two in letrozole vs. Clomid, read the letrozole for fertility guide, or, if you have PCOS, start with trying to conceive with PCOS.
Can you take Clomid on your own?
No. Clomiphene is prescription-only in the US, and the label's own requirements, from ruling out pregnancy and cysts to stopping after six cycles, assume a clinician is watching each cycle. Taking it without a workup risks treating the wrong problem while exposing her to twins, OHSS and vision effects.
The FDA's BeSafeRx guidance lists the warning signs of an unsafe online pharmacy, starting with one that does not require a prescription. A safe one requires a prescription, has a US address and phone number, a licensed pharmacist on staff and a state pharmacy license. Prices that seem too good to be true are another warning sign the FDA names.
How a Clomid prescription works in Gala Fertility
Gala Fertility is built the way the label reads. You start with a $29.99 introductory video meeting with our care team. If you go ahead, both of you are tested: her bloodwork at a Quest lab and a pelvic ultrasound near you, his semen analysis with a kit sent to your home. A licensed clinician reviews every result with you on video.
Ovulation induction with letrozole or clomiphene is a standard first-line approach, usually tried before IUI or IVF. If your results point to it, your clinician prescribes one of them one month at a time, shipped to your door, with a check-in at the end of every cycle for up to six cycles. If the results point elsewhere, such as a blocked tube or a severe male factor, your clinician tells you why and refers you to a fertility clinic or a reproductive urologist.
After that, your plan is one all-inclusive price per cycle, shown before you commit: medication if prescribed, a check-in after every cycle, your video visits, messages with your care team and all program tests for both of you.
Frequently asked questions
Can I get a Clomid prescription online?
Yes, from a licensed clinician who has evaluated you. The clomiphene label requires other causes of infertility to be ruled out first, so a safe online prescription follows testing of both partners. Gala Fertility prescribes letrozole or clomiphene only when the results show it is right for you.
Can I take Clomid on my own without a doctor?
No. Clomiphene is prescription-only, and its label asks for a pregnancy test and a check for ovarian cysts before each course, a dose ceiling of 100 mg a day, and a stop after about six cycles. Those steps need a clinician.
What is the starting dose of Clomid?
The label starts at 50 mg a day for 5 days, beginning on or about day 5 of the cycle. If she does not ovulate, the next course is 100 mg a day for 5 days. Higher doses or longer courses are not recommended.
What are the chances of twins on Clomid?
In the label's clinical trials, 7.98% of pregnancies were multiples, mostly twins at 6.9%. Triplets or more made up about 1%.
What side effects mean I should call right away?
Any blurred vision, spots or flashes, and abdominal pain or swelling, nausea, vomiting, diarrhea or sudden weight gain. The first can be a visual reaction and the second can be early ovarian hyperstimulation syndrome.
Does Clomid work for male infertility?
The clomiphene label says there are no adequate or well-controlled studies showing it is effective for male infertility. His results are part of the workup so the cause is treated, not guessed.
