About tranexamic acid
|Type of medicine||Antifibrinolytic|
|Used for||To prevent or treat heavy bleeding|
|Available as||Tablets and injection|
Tranexamic acid is given to stop or reduce heavy bleeding. When you bleed, your body forms clots to stop the bleeding. In some people these break down causing too much bleeding. Tranexamic acid works by stopping the clots from breaking down and so reduces the unwanted bleeding.
It is used to control bleeding in a number of different conditions. It reduces unwanted or heavy bleeding following some surgery (such as surgery on the prostate, bladder, or cervix), nosebleeds, heavy periods (menorrhagia), bleeding inside the eye, tooth extraction in people who bleed more easily than normal, and in a condition called hereditary angio-oedema.
Before taking tranexamic acid
Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking tranexamic acid it is important that your doctor or pharmacist knows:
- If you are pregnant or breast-feeding.
- If you have blood vessel problems such as thrombosis.
- If you have kidney problems, or have blood in your urine.
- If you have ever had convulsions (fits).
- If you have ever had a blood clotting problem called disseminated intravascular coagulation.
- If you are taking other medicines, including those available to buy without a prescription, herbal and complementary medicines.
- If you have ever had an allergic reaction to any medicine.
How to take tranexamic acid
- Before you start this treatment, read the manufacturer's printed information leaflet from inside your pack. The leaflet will give you more information about the specific brand of tranexamic acid you have been given, and a full list of possible side-effects from taking it.
- Your doctor or pharmacist will tell you how many tablets to take, when to take them, and for how long. Your dose will also be on the label of the pack. The usual dose is two or three tablets, two or three times a day, but your doctor will tell you what dose is right for you. Take the tablets exactly as your doctor has told you.
- These tablets should be swallowed whole with a drink of water, and should not be crushed or chewed.
- You may take the tablets before or after food.
- If you forget to take a dose, do not worry, just leave out the missed dose and take the next dose when it is due. Do not take two doses together to make up for a forgotten dose.
Getting the most from your treatment
- Try to keep your regular appointments with your doctor. This is so your doctor can check on your progress.
- If you are taking tranexamic acid over a long period of time, you will need regular blood tests to check your liver.
- If you are having an operation or dental treatment, tell the person carrying out the treatment that you are taking tranexamic acid.
Can tranexamic acid cause problems?
