Heavy periods can often be controlled with medication, and most people start with options they can try at home before considering anything more involved. Clinically, a period is considered heavy when you lose more than 80 mL of blood per cycle or bleed for longer than 7 days. In practical terms, that looks like soaking through a pad or tampon every hour for several hours, passing clots larger than a quarter, or needing to double up on protection. If that sounds familiar, there are effective strategies ranging from over-the-counter pills to longer-term hormonal options.
Why Some Periods Are Heavier Than Others
Before jumping to treatment, it helps to understand what might be driving the heavy flow, because the best approach depends partly on the cause. Doctors group the structural causes of heavy bleeding into four main categories: polyps, adenomyosis, fibroids, and (rarely) malignancy.
Fibroids are among the most common culprits. Those that grow into or just beneath the uterine lining tend to cause heavy, unpredictable bleeding because they lack normal tissue covering them. Fibroids embedded deeper in the uterine wall cause heavy but more predictable periods by increasing the surface area that sheds each month. Adenomyosis, where tissue similar to the uterine lining grows into the muscular wall of the uterus, classically causes both heavy bleeding and painful cramps. Its incidence rises with age during the premenopausal years. Endometrial polyps more often cause light spotting between periods, though they can contribute to heavier flow in some cases.
Many people with heavy periods have no structural problem at all. Hormonal imbalances, thyroid conditions, clotting disorders, and conditions like polycystic ovary syndrome (PCOS) can all increase menstrual blood loss. Identifying the underlying cause, if there is one, usually starts with a pelvic ultrasound. For people over 45, or younger people with certain risk factors like obesity, diabetes, or chronic irregular cycles, an endometrial biopsy may also be recommended to rule out precancerous changes.
Anti-Inflammatory Medications (NSAIDs)
One of the simplest first steps is taking an NSAID like ibuprofen or naproxen during your period. These reduce menstrual blood loss by about 30% and have the added benefit of relieving cramps. You take them at the start of your period and continue for the heaviest days. The downside is that NSAIDs can cause stomach upset, nausea, or digestive issues, especially with repeated use over many cycles. For mild to moderately heavy periods, though, this alone can make a noticeable difference.
Tranexamic Acid
Tranexamic acid is a non-hormonal prescription medication that works by helping blood clots stay stable in the uterine lining during your period. You take it only on heavy bleeding days, up to five days per cycle, and it reduced menstrual blood loss by about 40% in clinical trials compared to roughly 8% with a placebo. That translates to a meaningful reduction in flow for most users.
The key advantage of tranexamic acid is that it doesn’t affect your hormones or your cycle length. You take it three times a day during your period and stop when bleeding lightens. It’s been used for heavy menstrual bleeding in other countries for decades and is now widely available. It can be combined with other approaches, and the American College of Obstetricians and Gynecologists lists it among the first-line medical treatments for heavy bleeding.
Hormonal Options
Hormonal treatments are often the most effective long-term strategy. The hormonal IUD stands out here. In studies comparing it head-to-head against oral medications, the IUD consistently performed better. At six months, users saw an 86 to 90% reduction in bleeding scores, compared to 41 to 61% with oral hormonal treatments or tranexamic acid. At 12 months, the IUD maintained an 83 to 87% reduction. Many users eventually have very light periods or no periods at all.
The hormonal IUD works by releasing a small amount of a progestin directly into the uterus, which thins the uterine lining. Once placed, it lasts for several years and requires no daily effort. The first few months can involve irregular spotting, but bleeding typically improves steadily after that.
Combined oral contraceptives (the pill) and oral progestins are also effective options. The pill regulates your cycle and thins the lining, reducing flow. Oral progestins can be taken cyclically or continuously depending on your situation. These are good choices if you prefer something you can start and stop easily, though they require daily adherence and don’t reduce bleeding quite as dramatically as the IUD for most people.
Watch for Iron Deficiency
Losing a lot of blood every month drains your iron stores, and many people with heavy periods develop iron deficiency without realizing it. Symptoms include fatigue, brain fog, shortness of breath during normal activity, and feeling cold. A ferritin level below 15 is diagnostic of iron deficiency, and levels between 15 and 30 suggest probable deficiency. Iron replacement should begin as soon as deficiency is detected, even before anemia develops on a blood count.
If you’ve had heavy periods for a while, it’s worth asking for a ferritin test specifically, since a standard blood count can look normal even when your iron stores are depleted. Oral iron supplements are the typical starting point, taken with vitamin C to improve absorption. Expect it to take several weeks to feel a difference and a few months to fully replenish your stores.
Supplements With Limited Evidence
Some people look to vitamins before trying medication. There is limited evidence that vitamin C (200 mg three times daily) combined with bioflavonoids reduced heavy bleeding in a small study of 16 patients. Vitamin K has some historical clinical support, though the research is thin. Neither of these is strong enough to rely on as a primary treatment if your bleeding is significantly affecting your quality of life, but they’re unlikely to cause harm and could be worth trying alongside more proven options.
When Medication Isn’t Enough
If medications haven’t controlled your bleeding, or if a structural problem like fibroids is the source, procedural options come into play. Endometrial ablation is one of the less invasive surgical choices. It destroys the uterine lining using heat, cold, or other energy sources. Most people return to normal activities within 48 hours and notice lighter periods within two to three months. Some stop having periods entirely. It’s not appropriate if you want to become pregnant in the future, since it disrupts the lining needed for implantation.
For fibroids specifically, removal of the fibroid (myomectomy) or procedures that cut off its blood supply can address the root cause while preserving the uterus. Hysterectomy, the removal of the uterus, is a definitive solution but is generally reserved for people who haven’t responded to other treatments and are done with childbearing.
Choosing Your Starting Point
Medical management is the recommended initial approach for most people. Where you start depends on your priorities. If you want something simple and non-hormonal, NSAIDs or tranexamic acid are reasonable first steps. If you want the most effective long-term reduction with minimal daily effort, the hormonal IUD has the strongest track record. Combining approaches, like an NSAID for cramps plus a hormonal method for flow, is common and often more effective than either alone.
Tracking your bleeding for two or three cycles before and after starting treatment gives you and your provider a clear picture of whether something is working. Note how many pads or tampons you use, whether you’re passing clots, and how many days you bleed. That information makes it much easier to adjust your plan if the first approach doesn’t get you where you want to be.
