Several proven methods can reduce menstrual blood flow, ranging from over-the-counter medications to hormonal options and simple dietary changes. The right approach depends on how heavy your bleeding is and whether you’re looking for cycle-by-cycle relief or a long-term solution. A normal period produces about 30 to 40 milliliters of blood, while heavy menstrual bleeding (called menorrhagia) is clinically defined as more than 80 milliliters per cycle.
Anti-Inflammatory Medications
Nonsteroidal anti-inflammatory drugs, commonly called NSAIDs, are one of the simplest first steps. These include ibuprofen and prescription options like mefenamic acid. They work by lowering your body’s production of prostaglandins, hormone-like chemicals that trigger the uterine lining to shed and blood vessels to open wider. Fewer prostaglandins means less bleeding and, as a bonus, less cramping.
In clinical trials, mefenamic acid taken from the start to the finish of a period reduced heavy bleeding reports by 56% compared to a placebo. Over-the-counter ibuprofen works through the same mechanism, though the effect tends to be more modest. The key is timing: you start taking the medication at the very beginning of your period (or even a day before, if your cycle is predictable) and continue through your heaviest days. Taking it only after bleeding gets heavy means you’ve missed the window when it’s most effective.
Tranexamic Acid
Tranexamic acid takes a completely different approach from NSAIDs. Instead of reducing prostaglandins, it helps your blood clot more effectively by stabilizing the clots your body naturally forms in the uterine lining. Normally, those clots break down quickly, but tranexamic acid slows that breakdown, so bleeding tapers off faster.
Randomized trials show it reduces menstrual blood loss by 34% to 59% compared to placebo. It’s taken only during your period, typically for up to five days, and it doesn’t contain hormones. In the United States, it’s available by prescription under the brand name Lysteda. It’s a good option if you want cycle-by-cycle control without altering your hormones or fertility.
Hormonal Birth Control
Hormonal methods are among the most effective ways to reduce flow because they thin the uterine lining itself, meaning there’s simply less tissue to shed each month.
Combined Oral Contraceptives
The standard birth control pill (containing both estrogen and progestin) reduced heavy bleeding by about 37% in trials involving over 400 patients. Beyond reducing flow, the pill makes periods more predictable and shorter. Some people use extended-cycle regimens to skip periods altogether for months at a time, though breakthrough spotting is common in the first few cycles.
Hormonal IUD
The hormonal IUD (which releases a small amount of progestin directly into the uterus) is the most effective nonsurgical option available. In one study, participants experienced a median blood loss reduction of 93% by the third cycle and nearly 98% by the sixth cycle. Many people stop having periods entirely within a year. The device lasts several years once placed, making it essentially hands-off after insertion. It’s often recommended as a first-line treatment for heavy periods specifically because of how dramatic the results are.
Dietary and Supplement Approaches
If you prefer to start with less intensive options, a few supplements have clinical evidence behind them, though the studies are smaller.
Vitamin C combined with plant-based compounds called flavonoids may help strengthen the walls of small blood vessels in the uterine lining, reducing the amount of blood that escapes during shedding. In one study, 88% of women with heavy periods improved when taking 200 mg of vitamin C alongside 200 mg of flavonoids three times daily. A separate trial using a specific flavonoid blend (predominantly diosmin and hesperidin, at 1,000 mg per day starting five days before the expected period) found that 70% of participants experienced at least a 50% reduction in bleeding after three cycles.
Ginger has also shown promise. In a trial involving teenagers with heavy periods, 250 mg of ginger extract taken three times daily significantly reduced blood loss. The ginger was prepared in capsule form from fresh root. While these results are encouraging, the studies are small, so the effects may vary. These supplements are generally safe to try alongside other methods.
Iron and Hydration During Your Period
While not a way to reduce flow directly, staying on top of your iron intake matters if your periods are heavy. Losing more than 80 milliliters of blood per cycle can deplete your iron stores over time, leading to fatigue, brain fog, and shortness of breath. Eating iron-rich foods like red meat, lentils, and spinach during and after your period helps your body recover. Pairing iron-rich foods with a source of vitamin C (citrus, bell peppers) improves absorption. Staying well hydrated also helps your body replenish blood volume more efficiently.
Procedures for Severe Cases
When medications and hormonal methods haven’t worked well enough, a procedure called endometrial ablation destroys the uterine lining so it can no longer build up and shed as heavily. It’s a short outpatient procedure, not a major surgery. About 30% to 40% of women report their periods stop completely within the first year, and that number rises to around 50% by two to five years. Patient satisfaction rates range from 80% to 90%.
That said, ablation isn’t permanent for everyone. Roughly 20% to 25% of patients eventually need a hysterectomy within five years because bleeding or pain returns. It’s also not appropriate if you might want to become pregnant in the future, since the procedure damages the uterine lining in ways that make pregnancy unsafe.
Signs Your Bleeding Needs Urgent Attention
Heavy periods are common, but there’s a threshold where bleeding becomes a medical emergency. If you’re soaking through at least one pad or tampon every hour for more than two consecutive hours, that level of blood loss needs immediate evaluation. Other red flags include passing clots larger than a quarter, bleeding that lasts more than seven days, or feeling dizzy and lightheaded during your period. These symptoms can point to conditions like fibroids, clotting disorders, or hormonal imbalances that require specific treatment beyond general flow-reduction strategies.
