Tranexamic acid, often called TXA, is a medicine that helps stop or reduce bleeding. Doctors use it for heavy periods, nosebleeds, some dental procedures, and during surgery or trauma when bleeding is a concern. It works by slowing the breakdown of blood clots so bleeding can stop faster.
TXA blocks enzymes that dissolve clots. That makes it useful when bleeding is caused by the clotting process being too active in the wrong direction. The most common everyday use is for heavy menstrual bleeding—many people find their flow drops enough to avoid extra pads or tampons. Hospitals use IV TXA for things like postpartum hemorrhage, trauma, or major surgery to reduce blood loss. Dentists and ENT doctors may recommend short courses to control bleeding after procedures or for stubborn nosebleeds.
Typical oral dosing for heavy periods is 500 mg taken two or three times a day during the days with heavy bleeding. For surgical or emergency use, doctors often give a single IV dose (commonly 1 g) and may repeat it depending on the situation. Dosing changes if you have kidney problems, so doctors adjust amounts or give it less often.
Common side effects are mild: nausea, diarrhea, headache, and muscle cramps. More serious risks include blood clots—deep vein thrombosis or pulmonary embolism—so TXA is usually avoided if you have an active clot, a history of clots, or some clotting disorders. Tell your provider if you use hormonal birth control, have heart disease, or take medications that affect clotting.
Pregnancy and breastfeeding: IV TXA is used in emergencies like severe postpartum bleeding, but routine use in pregnancy should be guided by a doctor. If you're pregnant or breastfeeding, talk with your clinician before taking TXA.
Interactions and testing: TXA doesn’t mix well with some medicines that alter clotting. Your doctor may order blood tests or check kidney function before starting treatment.
Buying and storage tips: In many countries TXA requires a prescription. If you're thinking of buying online, use a licensed pharmacy, confirm they require a prescription, and check for clear contact info and secure payment. Keep tablets in original packaging at room temperature and follow the expiry date.
When to call a doctor: Seek immediate care if you notice signs of a blood clot—leg swelling, chest pain, or sudden shortness of breath—or if bleeding worsens despite taking TXA. Also call if you get severe side effects like persistent stomach pain or allergic reactions.
If heavy periods or a planned procedure are bothering you, bring TXA up with your healthcare provider. It’s a practical, well-used option for cutting bleeding, but the right dose and safety checks depend on your health history.
