Tranexamic tablet (tranexamic acid) is an antifibrinolytic medicine. It helps prevent or reduce abnormal bleeding by helping your blood clots stay formed.
What it’s used for (common indications)
- Heavy menstrual bleeding (menorrhagia)
- Bleeding during dental procedures or after surgery in people who have a higher risk of bleeding
- Nosebleeds or other kinds of bleeding where reducing clot breakdown is helpful
- In some cases, certain conditions like hereditary angioedema have been treated with tranexamic acid (under specialist advice)
How it’s taken
- Oral tablet, usually taken with water. Brand and tablet strength vary by country.
- The exact dose and how long you take it depend on why you’re using it, your age, kidney function, and other factors. A doctor will prescribe the right amount for you.
Common dosing concepts (not a substitute for your prescription)
- For adults with heavy menstrual bleeding, regimens commonly involve taking 650 mg two to three times daily for several days around the start of menses. Some regimens use different strengths or frequencies depending on local guidelines.
- Do not change your dose or duration without talking to your prescriber.
Possible side effects
- Common: nausea, stomach upset, diarrhea, headache, dizziness
- Less common: fatigue, vomiting
- Serious (rarer): blood clots or signs of a clot (leg swelling, chest pain, shortness of breath), severe allergic reactions, visual disturbances (rare)
Important precautions
- Do not use if you have active blood clots or a history of thrombosis, certain kidney problems, or a known allergy to tranexamic acid.
- Pregnancy and breastfeeding: discuss with a clinician if you’re pregnant or planning pregnancy. Safety in pregnancy is determined by the doctor based on risk/benefit.
- Interactions: it can interact with other medicines that affect bleeding or clotting. For example, it’s used carefully with other antifibrinolytics and with estrogen-containing medicines (which can raise clot risk).
If you’re considering this for yourself or someone else, tell me:
- Your country (brand names and prescription rules vary)
- The reason you’re asking (e.g., heavy periods, dental procedure, etc.)
- Any other medicines you’re taking and any kidney problems or pregnancy status
I can tailor the info (brand names, typical dosing ranges, and safety notes) to your situation. And if this is an urgent bleeding issue or you’ve already started the medicine and have concerning symptoms, seek medical care promptly.
