Loss of bone mineral density (BMD)
The use of depot medroxyprogesterone acetate subcutaneously (DMPA s.c.) reduces serum estrogen levels and is associated with a significant loss of bone mineral density as bone metabolism adapts to the lower estrogen levels. Bone loss is greater with longer duration of use, but BMD appears to increase once DMPA s.c. is discontinued and ovarian estrogen production rises.
Bone loss is particularly concerning during adolescence and early adulthood, a critical period of bone mass accretion. It is not known whether the use of DMPA s.c. by younger women reduces peak bone mass and thereby increases the risk of fractures later in life, i.e. after the menopause.
A study evaluating the effects of DMPA i.m. (Depo-Provera) on bone mineral density in adolescent women showed that its administration was associated with a statistically significant decrease in bone mineral density from baseline. Following discontinuation of DMPA i.m. in adolescents, however, the return of mean BMD to baseline values required 1.2 years at the lumbar spine, 4.6 years at the total hip and 4.6 years at the femoral neck (see section 5.1). In some participants, BMD did not fully return to baseline during follow-up, and the long-term outcomes of this group are unknown. In adolescents, SAYANA may be used, but only after other contraceptive methods have been discussed with the patient and have been found inadequate or unsuitable.
A large observational study in predominantly adult contraceptive users demonstrated that the use of DMPA i.m. does not increase the risk of bone fractures. Importantly, this study could not determine whether DMPA use affects fracture incidence later in life (see section 5.1 – Relationship between fracture incidence and use of DMPA i.m. in women of reproductive age).
In a woman of any age, if long-term use of medroxyprogesterone acetate for more than 2 years is required, the benefit-risk balance of treatment should be carefully reassessed. In particular, in women with medical risk factors for osteoporosis, other contraceptive methods should be considered before using SAYANA.
Significant risk factors for osteoporosis are:
Alcohol and/or tobacco use
Chronic use of medicinal products that reduce bone mass, e.g. anticonvulsants or corticosteroids
Low BMI or eating disorders, e.g. anorexia or bulimia
Previous spontaneous fracture
Family history of osteoporosis
Further information on changes in bone mineral density in both adult and adolescent women is provided in section 5.1. Adequate intake of calcium and vitamin D, whether from diet or supplements, is important for bone health in women of all ages.
Irregular menstrual cycle
Most women using SAYANA reported menstrual cycle disturbances. Patients should be appropriately counselled regarding the possibility of menstrual cycle disturbances and possible prolongation of anovulation. With increasing duration of SAYANA use, fewer patients report irregular bleeding and more report amenorrhoea. After the fourth dose, 39% of women reported amenorrhoea during the sixth month. At the twelfth month, 56.5% of women reported amenorrhoea. Changes in menstrual cycle across three contraceptive efficacy studies are shown in Figures 1 and 2. Figure 1 shows the increasing percentage of women experiencing amenorrhoea during the 12-month study. Figure 2 shows the percentage of women with spotting only, bleeding only, and bleeding plus spotting during the same period. In addition to amenorrhoea, menstrual cycle changes included irregular uterine bleeding, menorrhagia and metrorrhagia. If abnormal bleeding associated with the use of SAYANA is persistent or severe, appropriate investigation should be performed and treatment instituted.

Risk of cancer
Spotting only Bleeding only Bleeding and spotting
Long-term follow-up of patients receiving DMPA i.m. 150 mg has not shown any increase in the overall risk of ovarian, hepatic or cervical cancers and has demonstrated a persistent protective effect reducing the risk of endometrial carcinoma.
Breast cancer is rare in women under 40 years of age, whether they are using hormonal contraception or not.
The results of some epidemiological studies suggest a small difference in the risk of being diagnosed with breast cancer in women who are using or have used hormonal contraception compared with those who have never used it. The risk in current and recent DMPA users is small relative to the overall risk of breast cancer, particularly in young women (see below), and is no longer apparent 10 years after last use. The duration of use does not appear to be significant.

Meningioma
Cases of meningioma (both single and multiple) have been reported in patients treated with medroxyprogesterone acetate for a prolonged period (several years). Patients treated with SAYANA should be monitored for signs and symptoms of meningioma in accordance with clinical practice. If a patient is diagnosed with meningioma, treatment with SAYANA must be discontinued as a precautionary measure.
In some cases, regression of the meningioma has been observed following discontinuation of treatment with depot medroxyprogesterone acetate.
Thromboembolic disorders
Although medroxyprogesterone acetate has no causal relationship with the induction of thrombotic or thromboembolic disorders, it should not be readministered to any patient using SAYANA who experiences such an event, e.g. pulmonary embolism, cerebrovascular accident, retinal thrombosis or deep vein thrombosis. Women with a previous history of thromboembolic disorders have not been studied in clinical trials, and no information is available to support the safety of administering SAYANA to this population.
Anaphylaxis and anaphylactic reactions
If an anaphylactic reaction occurs, appropriate treatment should be instituted immediately. Severe anaphylactic reactions require immediate treatment.
Eye disorders
If partial or complete loss of vision, sudden onset of proptosis, diplopia or migraine occurs, further administration of the product should be withheld pending ophthalmological evaluation. If the examination reveals papilloedema or retinal vascular lesions, the product should not be administered further.
Changes in body weight
Changes in body weight are common but unpredictable. In phase 3 studies, body weight was monitored over 12 months. Half (50%) of the women remained within 2.2 kg of their original weight. 12% of women lost more than 2.2 kg, and 38% gained more than 2.3 kg.
Fluid retention
There is evidence that progestogens may produce some degree of fluid retention. The product should therefore be used with caution in patients whose pre-existing conditions could be adversely affected by weight gain or fluid retention.
Cessation of anovulation
After a single dose of SAYANA, the cumulative incidence of cessation of anovulation as measured by plasma progesterone level was 97.4% (38/39 patients) within one year of administration. After a 14-week therapeutic interval, the earliest return of ovulation was observed at one week, with a mean time to ovulation of 30 weeks. Women should be informed that there is a possibility of a delayed return of ovulation following use of the method, regardless of the duration of use. It should be noted, however, that amenorrhoea and/or irregular menstruation following discontinuation of hormonal contraception may be caused by an underlying condition associated with irregular menstruation, particularly polycystic ovary syndrome.
Psychiatric disorders
Depressed mood and depression are well-known adverse reactions to the use of hormonal contraception (see section 4.8). Depression can be severe and is a known risk factor for suicidal behaviour and suicide. Women should be advised to contact their physician in the event of mood changes and symptoms of depression, including shortly after starting treatment.
Protection against sexually transmitted infections
Women should be informed that SAYANA does not provide protection against sexually transmitted infections (STIs), including HIV infection (AIDS); however, the DMPA injection is sterile, so when administered correctly it will not expose them to STIs. Safer sex practices, including the correct and consistent use of condoms, reduce the risk of sexual transmission of STIs, including HIV.
The benefits and risks of each method of contraception must be evaluated individually for each woman.
Carbohydrates/metabolism
In some patients treated with progestins, glucose tolerance may decrease. Patients with diabetes should be carefully monitored during such treatment.
Hepatic function
If jaundice develops in a patient receiving SAYANA, discontinuation of the product should be considered (see section 4.3).
Hypertension and lipid metabolism disorders
Only limited data suggest that in patients with hypertension or lipid metabolism disorders who have received progesterone injections there is a slightly increased risk of cardiovascular events. If hypertension is recorded during treatment with SAYANA and/or progression of hypertension cannot be adequately controlled with antihypertensive therapy, treatment with SAYANA must be discontinued. Other risk factors for arterial thrombotic disorders include: hypertension, smoking, age, lipid metabolism disorders, migraine, obesity, positive family history, valvular heart disease and atrial fibrillation.
SAYANA should be used with caution in patients with 1 or more risk factors.
Other conditions
During pregnancy and during the use of sex steroids, the following conditions have been reported, although a relationship with the use of progestogens has not been established: jaundice and/or pruritus due to cholestasis, gallstone formation, porphyria, systemic lupus erythematosus, haemolytic uraemic syndrome, Sydenham's chorea, herpes gestationis, hearing loss due to otosclerosis.
If any of the conditions/risk factors mentioned above is present, the benefits of SAYANA should be weighed against the possible risks individually for each woman and discussed with her before deciding to initiate use of the product. In the event of worsening or initial onset of any of these conditions or risk factors, the woman should contact her physician. The physician will then decide whether use of SAYANA should be discontinued.
Laboratory tests
When sending samples for pathological examination, the pathologist should be informed of treatment with progestins. The physician should be informed that certain endocrine tests and tests of hepatic and blood components may be affected by treatment with progestins:
Plasma/urinary steroid levels are decreased (e.g. progesterone, estradiol, pregnanediol, testosterone, cortisol)
Plasma and urinary gonadotropin levels are decreased (e.g. LH, FSH)
Concentrations of sex hormone–binding globulin (SHBG) are decreased.
As the product contains methylparaben and propylparaben, it may cause allergic reactions (including delayed reactions) and, exceptionally, bronchospasm. This medicinal product contains less than 1 mmol sodium (23 mg) per 104 mg/0.65 ml, i.e. it is essentially "sodium-free".
