Clomiphene side-effect incidence rates below are drawn from FDA prescribing information and clinical trials. Most common effects are gastrointestinal and peak during dose changes.

Common side effects(5)

Incidence rates from clinical trials. Individual experience varies.

Clomiphene common side effects with incidence rates
Effect	Incidence	Note
Hot flashes	~10%	From estrogen-receptor blockade
Mood swings	~5%
Bloating / abdominal discomfort	5-6%
Breast tenderness	~2%
Visual changes (blurring, floaters)	~1.5%	Stop and call clinician — usually reversible

Serious side effects(3)

Less common but require medical attention.

Multiple pregnancy. ~7-10% twin rate — higher than letrozole or natural conception
Ovarian hyperstimulation syndrome (OHSS). Uncommon with oral clomiphene but possible
Visual disturbances. Persistent visual symptoms warrant discontinuation

Managing side effects(4)

Taken only 5 days early in the cycle — side effects are short-lived
Report any visual changes immediately (blurring, spots) — a specific clomiphene flag
Thins cervical mucus and endometrium in some women — clinician may monitor lining
If 3-6 cycles don't achieve ovulation/pregnancy, clinicians often switch to letrozole or add monitoring
