Heavy periods are common, and there are effective ways to reduce the flow, ranging from over-the-counter medications to hormonal options to procedures. A period is considered heavy when you lose more than about 80 milliliters (roughly 2.7 ounces) of blood per cycle. A practical way to gauge this: if you’re soaking through a pad or tampon every one to two hours, your flow is likely heavier than normal.
Over-the-Counter Pain Relievers That Also Reduce Flow
NSAIDs like ibuprofen and naproxen don’t just help with cramps. They reduce the amount of blood your uterus sheds. Ibuprofen at a dose of 1,200 mg per day (typically 400 mg three times daily) reduces menstrual blood loss by about 25% compared to placebo. Naproxen performs slightly better, cutting flow by roughly 30%. The key is timing: you need to start taking them just before or at the very beginning of your period and continue through the heaviest days. Taking ibuprofen only when pain strikes, rather than on a schedule, won’t have the same effect on bleeding.
Lower doses don’t work as well. One trial found that 600 mg of ibuprofen per day was no better than a placebo at reducing blood loss. So if you’ve tried ibuprofen before and didn’t notice a difference, the dose may have been too low.
Tranexamic Acid: A Stronger Non-Hormonal Option
If NSAIDs aren’t enough, tranexamic acid is a prescription medication specifically designed to reduce heavy menstrual bleeding without hormones. It works by helping blood clots stay intact in the uterine lining. Normally, your body breaks down clots as part of the shedding process, but tranexamic acid slows that breakdown, so the lining sheds with less active bleeding.
It reduces menstrual blood loss by 26% to 60%, making it significantly more effective than NSAIDs. You take it only during your period, typically for three to five days during the heaviest flow. It doesn’t change your cycle length, hormone levels, or fertility. For people who want meaningful relief without going on hormonal birth control, it’s one of the most effective options available.
Hormonal Options for Heavier Cases
Hormonal treatments are the most powerful medical option for heavy bleeding. The hormonal IUD stands out. Studies show it reduces menstrual blood loss by 71% to 94%, with most of that improvement happening in the first six to twelve months. One study comparing it directly to the combined birth control pill found an 87% reduction with the IUD versus 35% with the pill after a year. Many people with a hormonal IUD eventually have very light periods or stop bleeding altogether.
Combined oral contraceptive pills also help, thinning the uterine lining so there’s less tissue to shed each month. They typically reduce blood loss by 35% to 68%, depending on the person. Progestin-only pills, the hormonal shot, and the hormonal implant can all lighten periods too, though the effect varies more from person to person. If you’re not trying to get pregnant, hormonal methods offer both period management and contraception in one step.
What Might Be Causing Your Heavy Bleeding
Sometimes heavy periods aren’t just “how your body is.” They have a treatable underlying cause. Fibroids, which are noncancerous growths in the uterine wall, are one of the most common culprits. They can enlarge the uterine cavity, increasing the surface area that bleeds each month and interfering with the uterus’s ability to contract and clamp down on bleeding vessels.
Adenomyosis, a condition where tissue similar to the uterine lining grows into the muscular wall of the uterus, is another frequent cause. It leads to heavier bleeding through several mechanisms: the uterus develops a higher density of blood vessels, its contractions become abnormal, and the increased vascular surface area means more bleeding during each cycle. Adenomyosis also tends to cause intense cramping and pain during sex.
Thyroid disorders, clotting disorders (including von Willebrand disease, which is underdiagnosed in women), and polyps can all increase menstrual flow. If your periods have always been very heavy, or if they suddenly became heavier, it’s worth investigating whether one of these conditions is at play. Treating the root cause can sometimes resolve the bleeding entirely.
The Iron Problem That Makes Things Worse
Heavy periods drain your body’s iron stores over time, often leading to iron deficiency anemia. Symptoms include fatigue, weakness, dizziness, and feeling short of breath with minimal effort. Many people with chronically heavy periods assume this level of tiredness is just normal for them, not realizing their iron is depleted.
A blood test measuring ferritin (your body’s stored iron) and hemoglobin can confirm whether you’re anemic. If your ferritin is low, iron supplementation can help restore your energy levels, but it won’t fix the bleeding itself. Addressing the bleeding and replenishing iron need to happen together.
Procedures When Medications Aren’t Enough
When medications don’t provide adequate relief, or when you’d prefer a more permanent solution, endometrial ablation is a minimally invasive procedure that destroys the uterine lining. It’s done as an outpatient procedure, usually takes under 10 minutes, and most people return to normal activities within a few days. Satisfaction rates range from 77% to 96%, and somewhere between 14% and 70% of people stop having periods entirely afterward, depending on the technique used.
The results aren’t always permanent. An estimated 18% to 38% of people who have ablation need a repeat procedure or hysterectomy within five years. Ablation is also not an option if you want to become pregnant in the future. For people who are done with childbearing and want a strong chance of dramatically lighter periods without major surgery, it fills an important gap between medications and hysterectomy.
Signs Your Bleeding Needs Urgent Attention
Most heavy periods are manageable with the options above, but certain patterns signal something more serious. The CDC identifies these as warning signs: soaking through one or more pads or tampons every hour for several consecutive hours, passing blood clots the size of a quarter or larger, or needing to change protection after less than two hours consistently. If your bleeding is at this level and you’re feeling lightheaded, dizzy, or your heart is racing, that combination suggests significant blood loss that needs prompt medical evaluation.
