Several proven options can reduce menstrual bleeding, ranging from over-the-counter pain relievers that cut flow by about 25-30% to hormonal IUDs that reduce it by more than 90%. The right approach depends on how heavy your bleeding actually is and whether an underlying cause is driving it.
Before choosing a strategy, it helps to know what counts as heavy. Clinically, heavy menstrual bleeding is defined as losing more than 80 milliliters of blood per cycle. In practical terms, that looks like soaking through a pad or tampon every hour for several consecutive hours, passing blood clots larger than a quarter, or bleeding that lasts longer than seven days.
Track Your Flow First
Knowing whether your bleeding is moderately heavy or truly excessive helps you and your doctor pick the right treatment. A simple tool called a pictorial blood loss assessment chart (PBAC) lets you do this at home. You record how many pads or tampons you use each day and note how saturated they are: lightly stained, moderately soaked, or fully soaked. Each level gets a point value, and clots get scored separately. A total score above 150 over your entire period correlates well with clinical heavy bleeding, with about 80-90% accuracy. Several free period-tracking apps now include versions of this chart, or you can simply keep a written log for two or three cycles to bring to an appointment.
Over-the-Counter Anti-Inflammatories
Common anti-inflammatory painkillers like ibuprofen and naproxen don’t just ease cramps. They also reduce menstrual blood loss by roughly 25-30% when taken just before and during your period. These drugs work by blocking the production of compounds called prostaglandins, which promote both uterine contractions and blood vessel dilation in the uterine lining. Less prostaglandin activity means less bleeding and less pain simultaneously.
The dose matters. In clinical trials, a higher daily dose of ibuprofen (1200 mg per day, split into doses) reduced flow by about 25% compared to placebo, while a lower dose (600 mg per day) showed no meaningful difference. Naproxen performed similarly, reducing blood loss by about 30%. For mild to moderate heavy bleeding, this is a reasonable first step since you can start it on your own without a prescription.
Tranexamic Acid
If anti-inflammatories aren’t enough, tranexamic acid is a non-hormonal option that reduces menstrual blood loss by 26-60%. It works by stabilizing blood clots. Normally, your body forms clots to slow bleeding, then breaks them down. Tranexamic acid slows that breakdown process in the uterine lining, so clots hold longer and you lose less blood. It’s taken only during the days of heavy bleeding, not throughout your cycle, which appeals to people who want to avoid daily medication. In head-to-head comparisons, tranexamic acid outperforms anti-inflammatories for flow reduction. It’s available by prescription in most countries.
Hormonal Options
Hormonal treatments are the most effective medical approach for reducing menstrual bleeding, and they come in several forms.
Hormonal IUD
The levonorgestrel-releasing IUD is considered a first-line treatment for heavy menstrual bleeding by major gynecological organizations. It thins the uterine lining locally, and the results are dramatic: blood loss drops by a median of 93% within three cycles and 97% by six cycles. Many users eventually stop having periods altogether. Because the hormone acts mostly within the uterus, systemic side effects tend to be milder than with oral hormones. A single device lasts up to five years, making it one of the most effective and low-maintenance options available. In quality-of-life studies, it performs comparably to hysterectomy.
Birth Control Pills and Other Hormonal Methods
Combined oral contraceptives thin the uterine lining and regulate your cycle, typically producing lighter, shorter, and more predictable periods. Continuous or extended-cycle pill regimens, where you skip the placebo week, can reduce the number of periods you have per year to four or fewer. Hormonal patches and vaginal rings work through the same mechanism. Progestin-only pills and injections are alternatives for people who can’t take estrogen. The reduction in bleeding varies more with these methods than with the IUD, but most people notice a meaningful difference within two to three cycles.
When a Structural Problem Is the Cause
Sometimes heavy bleeding isn’t just a matter of hormones or clotting. Uterine fibroids are the most common structural cause. These noncancerous growths increase bleeding through several mechanisms: they enlarge the surface area of the uterine lining, disrupt normal muscle contractions that help stop bleeding, promote the formation of fragile, abnormal blood vessels around the growth, and compress veins in the uterine wall, creating pockets of pooled blood. Endometrial polyps, adenomyosis, and endometriosis can also drive heavy periods.
If your bleeding started suddenly, has gotten progressively worse, or doesn’t respond to initial treatments, your doctor will likely investigate these possibilities with an ultrasound or other imaging. Fibroids can sometimes be managed with medications that block progesterone, which shrinks them and often stops bleeding during treatment. But for many women with significant fibroids, medical management eventually proves insufficient and surgical options become necessary.
Endometrial Ablation
For people who are done having children and want a permanent reduction without removing the uterus, endometrial ablation destroys the uterine lining using heat, cold, or radiofrequency energy. It’s a minimally invasive outpatient procedure. Satisfaction rates range from 77 to 96%, and between 14 and 70% of women stop having periods entirely afterward. At three years out, about 27% of women have no periods, rising to 40% at five years as the lining continues to thin. Failure rates requiring a repeat procedure or hysterectomy run between 5 and 16%.
Ablation is not an option if you might want to become pregnant in the future, have an active pelvic infection, or have endometrial hyperplasia or cancer. Fibroids that significantly distort the uterine cavity can also make the procedure unsuitable.
Iron and Nutrition
Heavy periods and iron deficiency form a cycle that often goes unrecognized. Losing large volumes of blood depletes your iron stores, which can leave you fatigued, short of breath, and pale. This connection is so frequently overlooked that researchers have noted it gets “normalized by society, healthcare providers, and affected girls and women themselves.” If your periods are heavy, getting your iron levels checked is worth doing, and supplementing if they’re low can significantly improve how you feel even before your bleeding itself is treated.
Vitamin K plays a role in blood clotting by activating several clotting factors. A true vitamin K deficiency can cause abnormally heavy bleeding, including severe menstrual flow, and correcting the deficiency resolves it. However, this is rare in healthy adults who eat a normal diet. Eating plenty of leafy greens supports adequate vitamin K levels, but supplementing beyond that won’t reduce normal or heavy periods if you aren’t deficient.
Putting It Together
The practical path for most people starts simple and escalates if needed. Tracking your flow for two or three cycles gives you data. Anti-inflammatories taken during your period can provide a 25-30% reduction with minimal effort. If that’s not enough, tranexamic acid offers stronger non-hormonal control at 26-60% reduction. A hormonal IUD delivers the most dramatic results of any reversible option, cutting blood loss by over 90%. And if a structural problem like fibroids is identified, treating the underlying cause directly may be the only way to get lasting relief. These approaches can also be combined: anti-inflammatories and tranexamic acid, for instance, work through different mechanisms and can be used together under medical guidance.
