Go to top of the page

4.2 Posology and method of administration

Route of administration

Oral.

Posology

Cyklo-f therapy is initiated only once heavy bleeding has started. The recommended dosage is 2 tablets 3 times daily for as long as needed, but for a maximum of 4 days. If there is very heavy menstrual bleeding, the dosage may be increased. A total dose of 4 g daily (8 tablets) should not be exceeded.

Cyklo-f can be used as long as periods remain regular and heavy.

Children: Not for use in children under 18 years of age.

Elderly patients: Not recommended for use in the elderly.

The following patients should consult their doctor prior to initiating treatment with Cyklo-f:

4.5 Interaction with other medicinal products and other forms of interaction

Cyklo-f will counteract the thrombolytic effect of fibrinolytic preparations.

4.6 Pregnancy and lactation

Pregnancy

Cyklo-f is contraindicated in pregnancy. Although there is no evidence from animal studies of a teratogenic effect, the usual caution with use of drugs in pregnancy should be observed.

Tranexamic acid crosses the placenta.

Lactation

Tranexamic acid passes into breast milk to a concentration of approximately one hundredth of the concentration in the maternal blood. An antifibrinolytic effect in the infant is unlikely.

Breastfeeding women should consult their doctor prior to taking Cyklo-f.

4.7 Effects on ability to drive and use machines

None known.

4.8 Undesirable effects

Gastrointestinal discomfort is the most common undesirable effect that may occur but disappear when the dosage is reduced.

Frequency of undesirable effects at a dose of 4g/day (MedDRA LLT):

Gastrointestinal disorders

Common (1/100 to <1/10):

Nausea, vomiting diarrhoea

Skin and subcutaneous tissue disorders

Uncommon (1/1,000 to <1/100)

Allergic skin reactions

Adverse Events:

Other adverse events have been reported with the use of tranexamic acid but the frequency of the reports cannot be estimated from the available data: thromboembolic events, retinal/artery occlusion and impaired colour vision or other visual disturbances.

4.9 Overdose

Symptoms may be nausea, vomiting, orthostatic symptoms and/or hypotension. Initiate vomiting, then stomach lavage, and charcoal therapy. Maintain a high fluid intake to promote renal excretion. There is a risk of thrombosis in predisposed individuals. Anticoagulant treatment should be considered.

5. PHARMACOLOGICAL PROPERTIES

Go to top of the page

5.1 Pharmacodynamic properties

Tranexamic acid is an antifibrinolytic compound which is a potent competitive inhibitor of the activation of plasminogen to plasmin. At much higher concentrations it is a non-competitive inhibitor of plasmin. The inhibitory effect of tranexamic acid in plasminogen activation by urokinase has been reported to be 6-100 times and by streptokinase 6-40 times greater than that of aminocaproic acid. The antifibrinolytic activity of tranexamic acid is approximately ten times greater than that of aminocaproic acid.

A 2001 study involving more than 800 women demonstrated a significant improvement in their quality of life when taking tranexamic acid.

5.2 Pharmacokinetic properties

Following oral administration, 1.13% and 39% of the administered dose were recovered after 3 and 24 hours respectively. Tranexamic acid administered parenterally is distributed in a two compartment model. Tranexamic acid crosses the placenta, and may reach one hundredth of the serum peak concentration in the milk of lactating women. Tranexamic acid crosses the blood brain barrier.

Following intravenous administration, the biological half-life of tranexamic acid has been determined to be 1.9 hours and 2.7 hours.
