1 Dosing Considerations Activelle® LD is a low-dose continuous combined Hormone Replacement Therapy (HRT) product intended for use in women with intact uteri. For initiation and continuation of treatment of postmenopausal symptoms, the lowest effective dose for the shortest duration should be used.
In women with amenorrhea and not taking HRT or women in transition from another continuous combined HRT product, treatment with Activelle® LD may be started on any convenient day. In women in transition from sequential HRT regimens, treatment should start right after their withdrawal bleeding has ended.
1 mg) should be taken orally once a day without interruption, preferably at the same time every day. Patients should be re-evaluated within 3-6 months after initiation of treatment, to assess response to treatment. 5 Missed Dose If the patient has forgotten to take a tablet, the tablet should be taken as soon as possible Activelle® LD Product Monograph Page 7 of 39 within the next 12 hours.
After 12 hours the tablet should be discarded and next dose taken at the normal time. Forgetting a dose may increase the likelihood of breakthrough bleeding and spotting.
1 Adverse Reaction Overview See 7 WARNINGS AND PRECAUTIONS regarding potential induction of malignant neoplasms and adverse effects similar to those of oral contraceptives. g. 2 Clinical Trial Adverse Reactions Clinical trials are conducted under very specific conditions.
Therefore, the frequencies of adverse reactions observed in the clinical trials may not reflect frequencies observed in clinical practice and should not be compared to frequencies reported in clinical trials of another drug. Adverse events reported by investigators in the Activelle® LD pivotal trial at a frequency of 1% are shown in Table 1 below.
The regimens evaluated Activelle® LD over a 6-month treatment period.

No adverse events reported The most frequently reported adverse events in the clinical trials with Activelle® LD tablets were vaginal hemorrhage (any release of blood from uterus), endometrial thickening (double layer measured at ≥ 5 mm) and headache.
The majority of AEs occurred with similar frequency in the treatment groups and were classified as mild or moderate in severity. As Activelle® LD Product Monograph Page 17 of 39 expected, the incidence of vaginal bleeding was higher in the continuous combined treatment groups Activelle® LD (25%) than in the placebo group (12%).
General For the treatment of postmenopausal symptoms, Hormone Replacement Therapy (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.
Carcinogenesis and Mutagenesis Breast Cancer Available epidemiological data indicate that the use of combined estrogen plus progestin by postmenopausal women is associated with an increased risk of invasive breast cancer. 04) and were at a more advanced stage compared with those diagnosed in the placebo group.
The percentage of women with abnormal mammograms (recommendations for short-interval follow-up, a suspicious abnormality, or highly suggestive of malignancy) was significantly higher in the estrogen plus progestin group versus the placebo group.
2 It is recommended that estrogens with or without progestins not be given to women with existing breast cancer or those with a previous history of the disease (see 2 CONTRAINDICATIONS). There is a need for caution in prescribing estrogens with or without progestins for women with known risk factors associated with the development of breast cancer, such as strong family history of breast cancer (first degree relative) or who present a breast condition with an increased risk (abnormal mammograms and/or atypical hyperplasia at breast biopsy).
Other known risk factors for the development of breast cancer such as nulliparity, obesity, early menarche, late age at first full term pregnancy and at menopause should also be evaluated. It is recommended that women undergo mammography prior to the start of HRT treatment and at regular intervals during treatment, as deemed appropriate by the treating physician and according to the perceived risks for each patient.
Taking estrogens with progestins may increase the density of breast tissue, potentially adversely affecting the capability of mammography to detect breast cancer. The overall benefits and possible risks of hormone replacement therapy should be fully considered and discussed with patients.

It is important that the modest increased risk of being diagnosed with breast cancer after 4 years of treatment with combined estrogen plus progestin HRT (as reported in the results of the WHI trial) be discussed with the patient and weighed against its known benefits.
Instructions for regular self-examination of the breasts should be included in this counselling. Endometrial Hyperplasia & Endometrial Carcinoma The risk of endometrial hyperplasia and carcinoma is increased when estrogens are administered alone for prolonged periods to women with intact uteri.
The role of a progestin, when combined with estrogen, is to prevent endometrial hyperplasia/carcinoma in women with Activelle® LD Product Monograph Page 9 of 39 intact uteri. The addition of a progestin for at least 12 days per cycle in non-hysterectomised women reduces this risk.

At 24 weeks, there were no differences between the groups in mean change of endometrial thickness, as evaluated by transvaginal ultrasound. Ovarian Cancer Some recent epidemiologic studies have found that the use of hormone replacement therapy (estrogen-alone and estrogen plus progestin therapies), in particular for 5 or more years, has been associated with an increased risk of ovarian cancer.
