Question 1

What is Tranexamic acid?

Accepted Answer

Tranexamic acid is a medication classified as an antifibrinolytic agent. It is a synthetic derivative of the amino acid lysine that helps the body manage how it processes blood clots.

The medication works by slowing the breakdown of blood clots in the body. By preventing these clots from dissolving too quickly, it helps to reduce or prevent excessive bleeding.

Question 2

What is Tranexamic acid used for?

Accepted Answer

Tranexamic acid is used to treat heavy menstrual bleeding and as a short-term adjunctive therapy in hemophilia to reduce or prevent bleeding.

Question 3

How does Tranexamic acid work?

Accepted Answer

Mechanism of Action

Tranexamic acid belongs to a class of medications known as antifibrinolytics. It works by slowing the breakdown of blood clots, a process naturally occurring in the body called fibrinolysis.

When the body experiences bleeding, it forms clots to seal blood vessels. These clots are held together by a protein called fibrin. To eventually clear these clots, the body uses an enzyme called plasmin. Tranexamic acid interferes with this process in the following ways:

Blocking plasminogen: It prevents the activation of plasminogen, which is the precursor to the enzyme that dissolves clots.

Inhibiting plasmin: It stops existing plasmin from binding to and breaking down the fibrin mesh that stabilizes a blood clot.

By keeping blood clots intact for a longer period, tranexamic acid helps to decrease the amount of blood lost. In the case of heavy menstrual periods, it reduces the volume of blood flow but does not stop the period entirely. When used during surgery or after an injury, it helps the body maintain the clots necessary to prevent excessive hemorrhage.

and others

Always consult with a healthcare professional about potential side effects.

Question 7

What drug class is Tranexamic acid?

Accepted Answer

Tranexamic acid belongs to the antifibrinolytic drug class.

Question 8

What is the dosage of Tranexamic acid and how do I take it?

Accepted Answer

Administration Methods

Tranexamic acid is available in two forms: oral tablets and an intravenous injection. The method of administration depends on the condition being treated.

Oral Tablets

Tablets are typically taken during the menstrual period for a set number of days.

Do not start taking the medication until your menstrual period has actually begun.

Swallow the tablets whole with a drink. Do not crush, chew, or break the tablets.

This medication can be taken with or without food.

Intravenous Injection

The injection form is used for short-term treatment and is administered directly into a vein by a healthcare professional in a medical setting.

Missed Dose

If you miss a dose of the oral tablets, take it as soon as you remember. If it is almost time for your next dose, skip the missed dose and follow your regular schedule. Do not take two doses at once to make up for a missed one.

Question 9

Is Tranexamic acid safe during pregnancy and breastfeeding?

Accepted Answer

There is limited information regarding the safety of tranexamic acid use during pregnancy. While animal studies have not shown evidence of harm to the developing fetus or impaired fertility, there are no adequate and well-controlled studies in humans. Because animal studies are not always predictive of human response, tranexamic acid should be used during pregnancy only if a healthcare provider determines it is clearly needed.

Tranexamic acid is known to cross the placenta and can be found in the umbilical cord blood at levels similar to those in the mother's blood.

Tranexamic acid is excreted into human breast milk. The concentration found in milk is approximately 1% of the concentration found in the mother's blood. Because the medication passes into breast milk, healthcare providers recommend exercising caution when using it while nursing. It is important to discuss the potential risks and benefits with a doctor before breastfeeding while taking this medication.

Question 10

What forms and strengths does Tranexamic acid come in?

Accepted Answer

Tranexamic acid is supplied in the following formats:

Oral Tablet: This form is taken by mouth. It is typically used for the treatment of heavy menstrual bleeding.

Intravenous Injection: This form is a solution administered by a healthcare professional directly into a vein. It is generally used for the short-term prevention or reduction of bleeding during and after medical procedures, such as dental work in patients with certain bleeding disorders.

Question 11

What is the FDA approval status of Tranexamic acid?

Accepted Answer

FDA Approval and Indications

The U.S. Food and Drug Administration (FDA) has approved tranexamic acid in both oral and injectable forms for specific medical conditions. The oral tablet is indicated for the treatment of cyclic heavy menstrual bleeding. The injectable form is approved for short-term use (two to eight days) in patients with hemophilia to reduce or prevent hemorrhage during and after tooth extraction.

Safety Communications

The FDA has issued safety alerts regarding the risk of medication errors involving tranexamic acid injection. There have been reports of the drug being accidentally administered intrathecally (into the spinal canal) when it was mistaken for anesthetic agents like bupivacaine or ropivacaine. Inadvertent spinal administration is a serious error that can lead to:

Seizures

Permanent neurological injury

Death

To prevent these errors, the FDA recommends that healthcare providers implement clear labeling and store tranexamic acid separately from medications intended for spinal administration.

Regulatory Status

Tranexamic acid is a prescription-only medication. It is not currently subject to a Risk Evaluation and Mitigation Strategy (REMS) program. While it is used in various clinical settings, its officially recognized indications are limited to those established during the FDA approval process.

Question 12

What should I know about Tranexamic acid and menorrhagia?

Accepted Answer

How it Works

Tranexamic acid belongs to a class of medicines called antifibrinolytics. It works by slowing the breakdown of blood clots, which helps to decrease the volume of blood lost during menstruation. It does not stop the menstrual cycle entirely, but rather makes the bleeding less heavy.

Usage and Administration

For the treatment of heavy menstrual bleeding, tranexamic acid is typically taken as an oral tablet. Key usage instructions include:

Schedule: The medication is only taken during the days of the menstrual period, usually for a maximum of five days. It is not intended for daily use throughout the month.

Dosage: It is often taken three times a day once heavy bleeding begins.

Limitations: This medication does not provide contraception and does not protect against sexually transmitted infections. It is also not used to treat symptoms like menstrual cramps.

Safety and Precautions

Because tranexamic acid affects how blood clots, it carries specific risks:

Blood Clot Risk: There is a risk of developing serious blood clots in the legs, lungs, or brain. This risk may be significantly increased if the medication is taken alongside hormonal contraceptives, such as the pill, patch, or ring.

Pre-existing Conditions: It is generally avoided in individuals with a history of blood clots or those with certain vision problems.
