You usually cannot safely stop a period instantly
Use a menstrual cup, tampon, or pad for management rather than trying to stop bleeding
Take ibuprofen or naproxen only if you normally can use NSAIDs and follow the label
Use hormonal birth control as prescribed by a clinician to reduce or skip periods
Ask a clinician about continuous birth control pills, the patch, the ring, or a hormonal IUD
Ask a clinician about prescription options such as tranexamic acid if periods are heavy
Rest, hydrate, and use a heating pad for comfort
Seek urgent medical care if you soak through a pad or tampon every hour for 2 hours, feel faint, have severe pain, or might be pregnant
See a clinician if your periods are very heavy, prolonged, irregular, or suddenly different
