Several types of pills can stop or significantly reduce your period, ranging from prescription hormonal contraceptives to short-term delay tablets. The most effective option is a combined birth control pill taken continuously, skipping the placebo (inactive) pills so you never trigger a withdrawal bleed. Other choices include progestin-only pills, a prescription tablet called norethisterone for short-term delay, and even high-dose ibuprofen for modest flow reduction in a pinch.
Which one makes sense depends on whether you want to stop periods long-term, delay one specific period, or just lighten a heavy flow.
Combined Birth Control Pills (Continuous Use)
Standard combination birth control pills contain two hormones that prevent ovulation and thin the uterine lining. A typical pack includes 21 active pills and 7 placebo pills. The bleeding you get during that placebo week isn’t a true period. It’s a withdrawal bleed triggered by the drop in hormones, and it was built into early pill designs to mimic a natural cycle. It is not medically necessary.
To stop your period, you simply skip the placebo pills and start a new pack of active pills immediately. This keeps hormone levels steady so the uterine lining stays thin with nothing to shed. The American College of Obstetricians and Gynecologists confirms this is safe: these methods thin the lining of the uterus, so there is no buildup of tissue, and skipping periods does not affect future fertility or increase cancer risk. Continuous use of combined pills actually decreases the risk of certain cancers.
Some pill brands are specifically packaged for extended or continuous use. A 91-day pack gives you a period roughly every three months, while a 365-day pack is designed to be taken every single day with no breaks. On the 365-day pack, some people stop bleeding entirely, while others experience much lighter periods. You can also achieve continuous dosing with any standard monophasic pill (one where every active pill has the same dose) by discarding the placebos and moving to the next pack.
Breakthrough Bleeding
The main downside of continuous use is unscheduled spotting, especially in the first few months. Breakthrough bleeding is more common with low-dose pills, in people who smoke, and when pills aren’t taken at the same time each day. If spotting becomes persistent, scheduling a planned withdrawal bleed every three to four months gives the uterus a chance to shed any minimal buildup and often resolves the issue. Consistency matters: taking your pill at the same time daily reduces spotting significantly.
Progestin-Only Pills
Progestin-only pills (sometimes called the minipill) contain a single hormone and are an option for people who can’t take estrogen due to migraines with aura, blood clot risk, or other reasons. Their effect on periods is less predictable than combined pills. The results depend heavily on which type of progestin the pill contains.
Older formulations stop periods in only about 2% of users after a year. Newer progestin-only pills perform better, with roughly 20 to 30% of users having no bleeding at all by 6 to 12 months. The trade-off is that bleeding patterns on these pills can be irregular and hard to predict, especially in the first few months. Some people get lighter, less frequent bleeding; others experience more frequent spotting before things settle.
Norethisterone for Short-Term Delay
If you need to push back one specific period for a vacation, wedding, or athletic event, norethisterone is a prescription progestin tablet designed exactly for this purpose. You start taking it three to five days before your expected period at a dose of 5 mg two or three times daily. Your period is held off for as long as you take the tablets, up to about 14 days. Bleeding typically starts two to three days after you stop.
Norethisterone is not a contraceptive at this dose, and it’s meant as a one-off solution rather than a long-term strategy. It’s widely prescribed in the UK, Australia, and parts of Europe. In the United States, it’s less commonly used for period delay specifically, but your provider can still prescribe it.
Ibuprofen and Other Anti-Inflammatories
You may have seen claims that high-dose ibuprofen can stop a period. The reality is more modest. Anti-inflammatory drugs reduce your body’s production of prostaglandins, chemicals that trigger the uterine lining to shed. At prescription-level doses (800 mg every six hours), ibuprofen may delay a period by a day or two at most. For a period already underway, it typically reduces flow by only 10 to 20%.
Cleveland Clinic specialists note they have not seen this approach proposed in medical journals and do not recommend trying it without guidance. Anti-inflammatories are genuinely useful for heavy cramps and can take the edge off a heavy flow, but they will not stop a period in any meaningful way.
Tranexamic Acid for Heavy Flow
Tranexamic acid is a non-hormonal prescription tablet that reduces menstrual bleeding by about 40%. It works by helping blood clots in the uterine lining stay intact longer, slowing the shedding process. It won’t stop your period entirely, but for people whose main concern is heavy flow rather than having no period at all, it can make a substantial difference. You take it only during the days of heaviest bleeding, not throughout the month.
Clinical Options for Full Suppression
For people who need complete menstrual suppression for medical reasons (endometriosis, severe anemia, certain disabilities, or gender-affirming care), doctors may prescribe stronger hormonal options beyond standard pills. These include injectable progestin given every three months, hormonal IUDs, implants placed under the skin of the arm, and in some cases injectable medications that temporarily shut down the hormonal signals from the brain that drive the menstrual cycle. These are typically managed by a gynecologist or specialist and are chosen when pills alone aren’t achieving adequate suppression.
The American College of Obstetricians and Gynecologists emphasizes that all hormonal methods used for menstrual suppression are reversible. They do not affect future fertility and do not increase cancer risk.
How Quickly Periods Return After Stopping
Fertility can return within the first month after stopping combined pills, patches, or rings. Some people see signs of ovulation within a few weeks, though it can occasionally take up to three months for cycles to fully normalize. Progestin-only and extended-cycle pills tend to have an even faster return to regular cycles. There is no “reset” period needed, and long-term use does not delay fertility beyond those initial one to three months of adjustment.
