Tranexamic Acid and its use in children with a bleeding disorder

Information for Parents/Patients/Carers/Families on Tranexamic acid, including dosage, usage and side effects.

This leaflet is for parents/ carers/ familites of children with a bleeding disorder. It provides information on the medication tranexamic acid that your child has been prescribed.

What is Tranexamic acid?

Tranexamic acid, or TXA as it is commonly known, is an anti-fibrinolytic medicine.

This type of drug helps the blood to clot. It does this as it prevents the breakdown of a protein called fibrin, which is the main protein in a blood clot.

Why do I need this information?

The manufacturer’s leaflet that comes in the box of Tranexamic acid is often aimed at adults and may not include all the information relevant to children and young people. This leaflet has been written specifically about the use of Tranexamic Acid in children and young people.

Why has my child been prescribed Tranexamic acid?

Tranexamic acid has been prescribed for your child as we have identified that they are experiencing bleeding symptoms.

Tranexamic acid is often used to prevent excessive bleeding, this can include post surgical procedures and dental procedures.

It is also used to prevent excessive bleeding from the nose, gums and bleeding from trauma.

It can also be very useful for heavy periods.

What forms can I get Tranexamic acid in ?

Tranexamic Acid comes in different forms.

• Tablets 500mg/tablet.
• Oral suspension 100mg/ml (this has a very short shelf life once opened so often tablets are a better option)
• Intravenous solution 100mg/ml

How is Tranexamic acid taken?

Tranexamic acid may be given by mouth as a tablet or liquid solution, both the tablets and the liquid solution can also be used as a mouthwash, the tablets can be crushed in water to do this.

In some situations your doctor or nurse may ask you to apply Tranexamic acid liquid or a crushed tablet directly to the area that is bleeding (this may be described as a topical application). This is particularly helpful for gum bleeding, mouth bleeding, nose bleeding and any superficial cuts and grazes that are taking a while to stop bleeding.

Tablets may be swallowed whole or crushed and taken with yoghurt or jam/honey. Tablets taste quite bitter so your child may needs lots of encouragement to take them.

If given as an oral suspension (liquid that is swallowed) the dose needs to drawn up in a syringe or onto a spoon and then given to the child for them to swallow.

If using tablets as a mouthwash after a dental extraction or for gum bleeding, the tablet should be crushed in some water then swilled around the mouth over the site of bleeding before swallowing.

Tranexamic acid Intravenous solution may also be injected into a vein. This would only ever be given to your child this way this way by a nurse or a doctor.

What dose of tranexamic acid will my child have?

Tranexamic acid is prescribed at 25mg/kg maximum dose 1 gram (2 tablets).If tablets are prescribed the dose will usually be rounded down to the nearest half tablet to help with ease of dosing. Your child’s dose will change as they grow.

When should my Child take Tranexamic acid?

For bleeding episodes your child will usually be asked to take their dose three times a day for 5 – 7 days. Doses should be at least 6 hours apart so it is best to space them out for example 8 am, 2 pm and 8pm.

Tranexamic acid may take 24 hours to take full effect, so if your child is due surgery we will ask you to start the dose from the evening prior to the procedure. Often after a surgical procedure you will be asked to continue the dosing for up to 14 days, three times a day.
