Clomid Alternatives: What Works Best for Ovulation Support?

If you’ve tried Clomid (clomiphene citrate) and hit a wall, you’re not alone. Many people need a different approach to trigger ovulation, whether due to side effects, resistance, or personal preference. Below we break down the most trusted alternatives, how they compare, and practical tips for getting started.

Why Switch From Clomid?

Clomid can cause mood swings, hot flashes, and thinning of the uterine lining in some users. It also stops working after several cycles for a portion of patients—a phenomenon called "Clomiphene resistance." When that happens, doctors often recommend another medication that targets hormone pathways more directly.

Top Alternatives to Consider

Letrozole (Femara) – This aromatase inhibitor lowers estrogen levels, prompting the pituitary gland to release more follicle‑stimulating hormone (FSH). Women often report fewer side effects and higher pregnancy rates compared with Clomid. Typical dosing starts at 2.5 mg on days 3–7 of the cycle.

Gonadotropins (FSH injections) – Brands like Gonal‑F, Menopur, or Bravelle contain purified FSH that directly stimulates the ovaries. They’re more expensive and require monitoring, but they work for many who don’t respond to oral pills.

Aromatase inhibitors (Anastrozole) – Similar to letrozole but less commonly used in fertility clinics. Some specialists prescribe it off‑label when patients need a milder estrogen suppression.

Metformin – Primarily for insulin resistance, metformin can improve ovulation in women with PCOS. It’s often combined with Clomid or letrozole to boost success rates.

Natural approaches (vitamin D, myo‑inositol) – While not a direct substitute, correcting deficiencies and supporting hormonal balance can enhance the effectiveness of any medication you’re on.

When choosing an alternative, your doctor will look at your health history, hormone levels, and previous response to Clomid. The goal is to pick the option that gives you the best chance of releasing a mature egg without unwanted side effects.

Most clinics start with letrozole because it’s easy to take, cheap, and has solid success data. If that fails, they move on to injectable gonadotropins, which provide precise control over follicle growth but need frequent blood tests and ultrasound scans.

Remember, every medication requires monitoring. Blood work will show how your estrogen and progesterone are changing, while ultrasounds track follicle size. Don’t skip appointments—these checks keep you safe and increase the odds of a healthy pregnancy.

If cost is a concern, ask about generic versions of letrozole or metformin. Some insurance plans cover them when prescribed for fertility reasons. For injections, many pharmacies offer discount programs that can cut prices by half.

Bottom line: You have several proven options if Clomid isn’t working for you. Talk to your reproductive endocrinologist about letrozole first, and be ready to discuss injectable gonadotropins if needed. With the right plan, ovulation induction can become a smooth part of your journey toward parenthood.
