Trisequens is a continuous sequential HRT product. The oestrogen is dosed continuously. The progestagen is added for 10 days of every 28 day cycle, in a sequential manner. One tablet should be taken orally once a day without interruption, preferably at the same time of the day, starting with oestrogen therapy (blue film-coated tablet) over 12 days, followed by 10 days of oestrogen/progestagen therapy (white film-coated tablet) and 6 days of oestrogen therapy (red film-coated tablet).
A regular shedding of the endometrium is usually induced during the red tablet phase. After intake of the last red tablet, treatment is continued with the first blue tablet of a new pack on the next day. In women who are not taking HRT or women in transition from a continuous combined HRT product, treatment with Trisequens may be started on any convenient day.
In women in transition from another sequential HRT regimen, treatment should begin the day following completion of the preceding regimen. 4). If the patient has forgotten to take a tablet, the tablet should be taken as soon as possible within the next 12 hours.
If more than 12 hours have passed, the tablet should be discarded. Forgetting a dose may increase the likelihood of breakthrough bleeding and spotting.
Clinical experience The most frequently reported adverse events in the clinical trials with Trisequens were vaginal bleeding and breast pain/tenderness, reported in approximately 10% to 20% of patients. Vaginal bleeding usually occurred in the first months of treatment.
Breast pain usually disappeared after a few months of therapy. All adverse events observed in the randomised clinical trials with a higher frequency in patients treated with Trisequens or similar HRT products as compared to placebo, and which on an overall judgement are possibly related to treatment are presented in the table below: System organ class Very common ≥ 1/10 Common ≥ 1/100 to < 1/10 Uncommon ≥ 1/1,000 to < 1/100 Rare ≥ 1/10,000 to < 1/1,000 Infections and infestations Genital candidiasis or vaginitis, see also Reproductive system and breast disorders Immune system disorders Hypersensitivity, see also Skin and subcutaneous tissue disorders Metabolism and nutrition disorders Fluid retention, see also General disorders and administration site conditions Psychiatric disorders Depression or depression aggravated Nervousness Nervous system disorders Headache, migraine or migraine aggravated Vascular disorders Thrombophlebitis superficial Pulmonary embolism Thrombophlebitis deep Gastrointestinal disorders Nausea Abdominal pain, abdominal distension or abdominal discomfort Flatulence or bloating Skin and subcutaneous tissue disorders Alopecia, hirsutism or acne Pruritus or Urticaria Musculoskeletal, connective tissue and bone disorders Back pain Leg cramps Reproductive system and breast disorders Breast pain or breast tenderness Menstruation irregular or menorrhagia Breast oedema or breast enlargement Uterine fibroids aggravated or uterine fibroids re-occurrence or uterine fibroids Endometrial hyperplasia Dysmenorrhoea, see also back pain under Musculoskeletal, connective tissue and bone disorders and abdominal pain under Gastrointestinal disorders General disorders and administration site conditions Oedema peripheral Drug ineffective Investigations Weight increased Post-marketing experience In addition to the above mentioned adverse drug reactions, those presented below have been spontaneously reported, and are by an overall judgement considered possibly related to Trisequens treatment.
For the treatment of postmenopausal symptoms, HRT should only be initiated for symptoms that adversely affect quality of life. In all cases, a careful appraisal of the risks and benefits should be undertaken at least annually, and HRT should only be continued as long as the benefit outweighs the risk.
Evidence regarding the risks associated with HRT in the treatment of premature menopause is limited. Due to the low level of absolute risk in younger women, however, the balance of benefits and risks for these women may be more favourable than in older women.
Medical examination/follow-up Before initiating or reinstituting HRT, a complete personal and family medical history should be taken. Physical (including pelvic and breast) examination should be guided by this and by the contraindications and warnings for use.
During treatment periodic check-ups are recommended of a frequency and nature adapted to the individual woman. Women should be advised what changes in their breasts should be reported to their doctor or nurse (see Breast cancer below).
g. mammography, should be carried out in accordance with currently accepted screening practices and modified to the clinical needs of the individual. Conditions which need supervision If any of the following conditions are present, have occurred previously and/or have been aggravated during pregnancy or previous hormone treatment, the patient should be closely supervised.

Reasons for immediate withdrawal of therapy Therapy should be discontinued in case a contraindication is discovered and in the following situations: - Jaundice or deterioration in liver function - Significant increase in blood pressure - New onset of migraine-type headache - Pregnancy.

4). Breast cancer risk An up to 2-fold increased risk of having breast cancer diagnosed is reported in women taking combined oestrogen-progestagen therapy for more than 5 years. The increased risk in users of oestrogen-only therapy is lower than that seen in users of oestrogen-progestagen combinations.
4). 0 * Taken from baseline incidence rates in England in 2015 in women with BMI 27 (kg/m²).

Since the background incidence of breast cancer differs by EU country, the number of additional cases of breast cancer will also change proportionately. 8 * Taken from baseline incidence rates in England in 2015 in women with BMI 27 (kg/m²).

Endometrial hyperplasia and carcinoma In women with an intact uterus, the risk of endometrial hyperplasia and carcinoma is increased when oestrogens are administered alone for prolonged periods. 8). After stopping treatment, the risk may remain elevated for more than 10 years.
The addition of a progestagen cyclically for at least 10 days per month/28 day cycle or continuous combined oestrogen-progestagen therapy in non-hysterectomised women prevents the excess risk associated with oestrogen-only HRT. Breakthrough bleeding and spotting may occur during the first months of treatment.
If breakthrough bleeding or spotting continues after the first months of treatment, appears after some time during therapy, or continues after treatment has been discontinued, the reason should be investigated, which may include endometrial biopsy to exclude endometrial malignancy.
Breast cancer The overall evidence shows an increased risk of breast cancer in women taking combined oestrogen-progestagen or oestrogen-only HRT that is dependent on the duration of taking HRT. 8). Results from a large meta-analysis showed that after stopping treatment, the excess risk will decrease with time and the time needed to return to baseline depends on the duration of prior HRT use.
When HRT was taken for more than 5 years, the risk may persist for 10 years or more. HRT, especially oestrogen-progestagen combined treatment, increases the density of mammographic images which may adversely affect the radiological detection of breast cancer.
Ovarian cancer Ovarian cancer is much rarer than breast cancer. Epidemiological evidence from a large meta-analysis suggests a slightly increased risk in women taking oestrogen-only or combined oestrogen-progestagen HRT, which becomes apparent within 5 years of use and diminishes over time after stopping.
8). e. deep vein thrombosis or pulmonary embolism. 8). Patients with known thrombophilic states have an increased risk of VTE and HRT may add to this risk. 3). Generally recognised risk factors for VTE include use of oestrogens, older age, major surgery, prolonged immobilisation, obesity (BMI > 30 kg/m2), pregnancy/postpartum period, systemic lupus erythematosus (SLE) and cancer.
There is no consensus about the possible role of varicose veins in VTE. As in all postoperative patients, prophylactic measures need to be considered to prevent VTE following surgery. If prolonged immobilisation is to follow elective surgery, temporarily stopping HRT 4 to 6 weeks earlier is recommended.
Treatment should not be restarted until the woman is completely mobilised. In women with no personal history of VTE but with a first degree relative […]
