Tranexamic acid, a synthetic derivative of the amino acid lysine, has gained significant attention in recent years for its efficacy in reducing bleeding in various medical conditions, including heavy menstrual bleeding, surgical procedures, and trauma. However, as with any medication, understanding its side effects is crucial for both patients and healthcare providers. This article aims to provide a comprehensive overview of tranexamic acid side effects, their implications, and what you need to know before taking this medication.
Common Side Effects of Tranexamic Acid
Tranexamic acid is generally well-tolerated, but like all medications, it can cause side effects. The most common side effects reported in clinical trials and post-marketing surveillance include:
- Gastrointestinal disturbances: nausea (14.1%), diarrhea (10.4%), and abdominal pain (6.5%)
- Headache (10.1%)
- Fatigue (8.3%)
- Dizziness (6.2%)
- Muscle cramps (5.5%)
These side effects are usually mild and transient, resolving on their own within a few days of treatment cessation. However, it is essential to consult a healthcare provider if these side effects persist or worsen over time.
Serious Side Effects: What to Watch For
While rare, tranexamic acid can cause serious side effects that require immediate medical attention. These include:
| Serious Side Effect | Description |
|---|---|
| Thrombosis | Increased risk of blood clots, including deep vein thrombosis (DVT) and pulmonary embolism (PE) |
| Visual Disturbances | Blurred vision, vision loss, or changes in color perception |
| Allergic Reactions | Anaphylaxis, including symptoms like difficulty breathing, rapid heartbeat, and swelling of the face, lips, tongue, or throat |
Patients with a history of thromboembolic events, cancer, or those taking other medications that increase the risk of thrombosis should be closely monitored while taking tranexamic acid.
