<strong>Depo</strong>-<strong>Provera</strong> 150 mg/ml (medroxyprogesterone acetate)<br />
ABBREVIATED PRESCRIBING INFORMATION (UK)<br />
(ALL CLAIMS)<br />
Please refer to the SmPC before prescribing <strong>Depo</strong>-<strong>Provera</strong> 150 mg/ml.<br />
Presentation: 1 ml Disposable syringe, containing 150 mg medroxyprogesterone acetate in a Sterile suspension for injection.<br />
Indication: Long-term contraceptive agent, in women who have been counselled concerning the likelihood of menstrual disturbance,<br />
potential delay in return to full fertility and risks of bone mineral density losses. Short-term contraception for the following (i) For<br />
partners of men undergoing vasectomy, until the vasectomy becomes effective, (ii) In women who are being immunised against rubella<br />
(iii) In women awaiting sterilisation. Dosage: First injection: 150mg intramuscular injection during the first 5 days of a normal<br />
menstrual cycle. Post Partum: Within 5 days post partum (if not breast-feeding). Women in puerperium can experience prolonged and<br />
heavy bleeding, therefore caution is required, and women should be advised accordingly. If the puerperal woman will breast-feed, the<br />
initial injection should be no sooner than 6 weeks post partum. Further doses: These should be given at 12 week intervals, however as<br />
long as the injection is given no later than 5 days after the 12 week interval, no additional contraception measures are required. For<br />
partners of men undergoing vasectomy, a second injection 12 weeks after the first may be necessary in a small proportion of patients<br />
where the partner's sperm count has not fallen to zero. If the dose repeat interval is greater than 89 days (12 weeks and 5 days) for any<br />
reason, then pregnancy should be excluded before the next injection is given and the patient should use additional contraceptive<br />
measures (e.g. barrier) for fourteen days after this subsequent injection. Elderly: Not appropriate. Children: <strong>Depo</strong>-<strong>Provera</strong> is not<br />
indicated before menarche (Refer to the Summary of Product Characteristics section 4.2 Posology and method of administration) Data<br />
in adolescent females (12-18 years) is available (see section 4.4 Special Warnings and Special Precautions for Use). Other than<br />
concerns about loss of BMD, the safety and effectiveness of <strong>Depo</strong>-<strong>Provera</strong> is expected to be the same for adolescents after menarche<br />
and adult females. Administration: By deep intramuscular injection. The sterile aqueous suspension should be vigorously shaken just<br />
before use to ensure the dose being given represents a uniform suspension. Contraindications: Known sensitivity to<br />
medroxyprogesterone acetate or any of its ingredients. Pregnancy, either for diagnosis or therapy. Known or suspected hormonedependent<br />
malignancy of breast or genital <strong>org</strong>ans. Patients <strong>with</strong> abnormal uterine bleeding, whether administered alone or in<br />
combination <strong>with</strong> oestrogen until a definite diagnosis has been established and the possibility of genital tract malignancy eliminated.<br />
Special Warnings and Precautions: Loss of bone mineral density, increasing <strong>with</strong> length of use. A risk: benefit assessment should be<br />
performed, especially in young or adolescent women and if use is anticipated to be long term (ie 2 years or longer). In adolescents and<br />
women <strong>with</strong> significant lifestyle and/or medical risk factors for osteoporosis, <strong>other</strong> methods of contraception should be considered<br />
before using <strong>Depo</strong>-<strong>Provera</strong>. Women should be counselled that there is a potential for delay in return to full fertility following use of<br />
the method, regardless of the duration of use. Disruption of normal menstrual cycle. Small increase in the risk of being diagnosed <strong>with</strong><br />
breast cancer, compared <strong>with</strong> non-users. Considered among the risk factors for osteoporosis. Weight Gain. Very few reports of<br />
anaphylactoid reactions. Pulmonary embolism, cerebrovascular disease or retinal thrombosis. Rare cases of thrombo-embolism have<br />
been reported. History of endogenous depression, including premenstrual-type depression, should be carefully monitored. Migraine or<br />
unusually severe headaches, acute visual disturbances of any kind, pathological changes in liver function and hormone levels. Patients<br />
<strong>with</strong> thromboembolic or coronary vascular disease should be carefully evaluated before treatment. Decreased glucose tolerance.<br />
Diabetic patients should be carefully monitored while receiving therapy. Increased and decreased in total cholesterol, triglycerides and<br />
low-density lipoprotein (LDL) cholesterol. Associated <strong>with</strong> a 15-20% reduction in serum high density lipoprotein (HDL) cholesterol<br />
levels. Potential for an increased risk of coronary disease should be considered prior to use. Patients <strong>with</strong> recent trophoblastic disease,<br />
exhibiting abnormal chorionic gonadotrophin levels. Pathologists should be informed of the patient's use of <strong>Depo</strong>-<strong>Provera</strong> if<br />
endometrial or endocervical tissue is submitted for examination. Results of certain laboratory tests may be affected. Refer to the<br />
Summary of Product Characteristics for more detailed information on Special Warnings and Precautions. Drug interactions:<br />
Aminoglutethimide administered concurrently may significantly depress bioavailability. The possibility of interaction (including oral<br />
anticoagulants) should be borne in mind in patients receiving concurrent treatment <strong>with</strong> <strong>other</strong> drugs. Pregnancy and Lactation:<br />
