Cyklokapron is a brand name for the antifibrinolytic medication tranexamic acid. It is supplied as a 500 mg oral pill and is classified under the therapeutic area “Heart & Blood Pressure” for regulatory reporting in Hong Kong, although its primary pharmacologic action relates to blood clot stabilization rather than cardiovascular pressure control. The product is available by prescription only and is regulated by the Hong Kong Department of Health in line with local drug-safety standards.
Tranexamic acid is a synthetic analogue of the amino acid lysine. It binds to lysine-binding sites on plasminogen, preventing its conversion to plasmin, the enzyme responsible for breaking down fibrin clots. By inhibiting fibrinolysis, tranexamic acid helps maintain stable blood clots at sites of vascular injury.
Because it strengthens clot formation without directly affecting blood pressure or heart rate, tranexamic acid is useful in conditions where excessive bleeding is a concern.
Tranexamic acid is approved by the U.S. Food and Drug Administration (FDA), the European Medicines Agency (EMA), and the Hong Kong Department of Health for the following indications:
These uses are supported by clinical trials demonstrating reduced transfusion requirements and shorter bleeding times.
Off-label uses such as treatment of epistaxis (nosebleeds) or post-operative bruising are occasionally reported, but they are not formally approved in Hong Kong.
These effects are typically mild and resolve without intervention. Patients should stay hydrated and take the pill with a full glass of water.
All dosing decisions must be individualized by a qualified healthcare professional.
Regular follow-up appointments are recommended to evaluate therapeutic response and adjust dosing as needed.

Yes, tranexamic acid is often prescribed to reduce bleeding after dental extractions, especially in patients on anticoagulants. The specific dosing schedule should be determined by your dentist or oral surgeon.
Tranexamic acid does not have a direct effect on blood pressure. However, any significant bleeding or fluid shifts may indirectly influence cardiovascular measurements, so routine monitoring is advisable.
The medication is legal in Hong Kong and most countries, but you should carry the original prescription label and a copy of the prescribing information when traveling. Check the destination country’s drug import regulations if you plan an extended stay.
Take the missed dose as soon as you remember, unless the next scheduled dose is within two hours. In that case, skip the missed dose and continue with the regular schedule; do not double the dose.
Cyklokapron tablets are typically round, white, and marked with the imprint “CYK-500.” Generic versions may have different shapes, colors, or imprints but contain the same 500 mg of tranexamic acid. Verify the imprint with your pharmacist.
Nosebleeds are an off-label indication. Some clinicians prescribe a short course of tranexamic acid for persistent epistaxis, but this use is not formally approved in Hong Kong and should be discussed with a healthcare provider.
When used appropriately for surgical bleeding control, tranexamic acid has been shown to reduce transfusion needs without a significant rise in thrombotic events. However, patients with a history of thromboembolism require careful risk assessment.
Both routes achieve antifibrinolytic activity, but intravenous administration provides faster plasma concentrations, which may be preferred in acute trauma. Oral tablets are convenient for outpatient or prophylactic use.
If stored as recommended-dry, at room temperature, and tightly sealed-the tablets retain full potency until the printed expiration date. Exposure to humidity or heat can degrade the medication faster.
Brand-name Cyklokapron may be priced higher than generic tranexamic acid tablets. In Hong Kong, the price difference can influence patient choice, especially for long-term use, but efficacy remains comparable. Consult your pharmacist for pricing options.
