4 CLINICAL PARTICULARS
4.1 Therapeutic indication
Reduction of heavy menstrual bleeding over several cycles in women with regular,
21-35 day cycles with no more than 3 days individual variability in cycle duration.
4.2 Posology and Method of Administration
Route of Administration Oral.
Posology
Femstrual 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.
Femstrual 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.
4.3 Contraindications
• Mild to moderate renal insufficiency
• Hypersensitivity to tranexamic acid or any of the excipients
• Active thromboembolic disease
• A previous thromboembolic event and a family history of thrombophilia.
• Haematuria
• Irregular menstrual bleeding
• Patients being administered warfarin or other anticoagulants
• Patients taking oral contraceptives
Severe renal failure because of risk of accumulation
4.4 Special Warnings and Precautions for Use
Patients should consult their doctor if menstrual bleeding is not reduced after three
menstrual cycles.
The following patients should consult their doctor prior to initiating treatment with
Femstrual:
• Women over the age of 45 years
• Patients who are obese and diabetic
• Those with polycystic ovary syndrome or a history of endometrial cancer in a first-degree relative
• Women receiving unopposed oestrogen or tamoxifen
Patients who experience visual disturbance should be withdrawn from treatment.
4.5 Interactions with other medicinal products and other forms of Interaction
Femstrual will counteract the thrombolytic effect of fibrinolytic preparations.
Drugs which also have effects on haemostasis should be given with caution to patients receiving tranexamic acid. There is a theoretical risk of increased potential for thrombus formation e.g. with oestrogens. Alternatively the action of the antifibrinolytic could be antagonised by thrombolytics.
Pregnancy and Lactation
4.6
Pregnancy: Femstrual 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 Femstrual.
4.7 Effects on ability to drive and use machines
Tranexamic Acid is not expected to affect a patients ability to drive and/or operate machines.
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 reported with the prescription use of tranexamic acid (by injection or by mouth) are listed below by System Organ Class and frequency.
Frequencies are defined as: very common (>1/l0), common (>1/100 and <1/10), uncommon ( >1/1000 and <1/100), rare ( > 1/10,000 and <1/1000) and very rare (<1/10,000) including isolated reports, not known (cannot be estimated from the available data).
System Organ Class
Immune system disorders |
Very rare: Hypersensitivity reactions including anaphylaxis |
Nervous system disorders |
Very rare: Convulsions |
Eye disorders |
Rare: Colour vision disturbances, retinal vein/artery occlusion Patients who experience disturbance of colour vision should be withdrawn from treatment. |
Vascular disorders |
Rare: Thromboembolic events (arterial or venous thrombosis). Hypotension, with or without loss of consciousness. This generally occurs as a consequence of rapid intravenous injection, but may occur exceptionally after oral administration. |
Renal and urinary disorders |
Not known: Renal infarct, acute renal failure |
Reporting of suspected adverse reactions
Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at: www.mhra.gov.uk/yellowcard
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
5.1 Pharmacodynamic properties
ATC Code: B02A A02.
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.
5.3 Preclinical safety data
There are no pre-clinical data of relevance to the prescriber which are additional to that already included in other sections of the Summary of Product Characteristics.
