Premia Continuous

Print Friendly, PDF & Email

Generic Name: conjugated estrogens and medroxyprogesterone acetate
Product Name: Premia Continuous

Indication: What Premia Continuous is used for

Premia Continuous helps to relieve the discomfort many women feel during and after menopause, including symptoms such as “hot flushes“, sweating and vaginal dryness. It also helps to prevent thinning of the bones (osteoporosis), which can cause fractures. Premia Continuous is used by women who still have a uterus (womb).

If your doctor thinks you will need to take HRT for a long time, including for the prevention of osteoporosis, your doctor will have considered the benefits and risks of other treatments before prescribing Premia Continuous for you.

Ask your doctor if you have any questions why Premia Continuous has been prescribed for you. Your doctor may have prescribed it for another use.

This medicine is available only with a doctor’s prescription.

Premia Continuous is not addictive.

Premia Continuous is not suitable for birth control, and it will not restore fertility.

This medicine is not expected to affect your ability to drive a car or operate machinery.

Warning

Estrogens and progestogens should not be used for the prevention of cardiovascular disease or dementia.

The Women’s Health Initiative (WHI) estrogen plus progestogen substudy reported increased risks of myocardial infarction, stroke, invasive breast cancer, pulmonary emboli, and deep vein thrombosis in postmenopausal women (50 to 79 years of age) during 5.6 years of treatment with conjugated estrogens (CE 0.625 mg) combined with medroxyprogesterone acetate (MPA 2.5 mg) per day relative to placebo.

The WHI estrogen-alone substudy reported increased risks of stroke and deep vein thrombosis in postmenopausal women (50 to 79 years of age) during 7.1 years of treatment with CE 0.625 mg per day relative to placebo.

The Women’s Health Initiative Memory Study (WHIMS), a substudy of WHI, reported an increased risk of developing probable dementia in postmenopausal women 65 years of age or older during 4 years of treatment with CE 0.625 mg combined with MPA 2.5 mg and during 5.2 years of treatment with CE 0.625 mg alone, relative to placebo. It is unknown whether this finding applies to younger postmenopausal women.

Other doses of CE and MPA and other combinations and dosage forms of estrogens and progestogens were not studied in the WHI clinical trials and, in the absence of comparable data, these risks should be assumed to be similar. Because of these risks, estrogens with or without progestogens should be prescribed at the lowest effective doses and for the shortest duration consistent with treatment goals and risks for the individual woman.

Action: How Premia Continuous works

Premia Continuous is a type of treatment called hormone replacement therapy (HRT) and contains the hormones, conjugated estrogens and medroxyprogesterone acetate (MPA).

Menopause occurs naturally in women typically between the ages of 45 and 55. During menopause, your body produces less estrogen than it did beforehand. This can cause symptoms such as “hot flushes”, a sudden, intense feeling of heat and sweating throughout the body. Some women also have problems with dryness of the vagina causing discomfort during or after sexual intercourse. Some women develop osteoporosis during or after menopause. This is a thinning of the bones that makes them weaker and more likely to break, especially the bones of the spine, hip and wrist.

When given during or after menopause, estrogens can help control the symptoms.

Conjugated estrogens and MPA are similar to the hormones produced by the ovaries before menopause.

Women who still have a uterus must take both estrogen and progestogen as part of HRT. This is because taking estrogen on its own may lead to irregular bleeding and a disorder of the uterine lining (endometrium) called endometrial hyperplasia, which can lead to endometrial cancer. Progestogens such as MPA help protect the uterine lining from developing this disorder.

The active ingredients are conjugated estrogens and MPA:

  • Each peach, oval Premia 2.5 Continuous Tablet contains conjugated estrogens 0.625 mg and MPA 2.5 mg, and is printed with “0.625/2.5” in black ink;
  • Each blue, oval Premia 5 Continuous Tablet contains conjugated estrogens 0.625 mg and MPA 5 mg and is printed with “0.625/5” in black ink.

These inactive ingredients are also found in Premia 2.5 Continuous and Premia 5 Continuous lactose monohydrate, methylcellulose, microcrystalline cellulose, powdered cellulose, povidone, sucrose, magnesium stearate, calcium phosphate, calcium sulfate, glyceryl monooleate, macrogol 20000, shellac, stearic acid, titanium dioxide, carnauba wax, and black ink.

The colouring agent found in Premia 2.5 Continuous is red iron oxide.

The colouring agent found in Premia 5 Continuous is indigo carmine.

  • Dizziness;
  • Feeling sleepy or tired;

While you are taking Premia Continuous

Things you must do

Tell any doctors, dentists and pharmacists who treat you that you are taking Premia Continuous.

If you are about to take any new medicines, tell your doctor or pharmacist that you are taking Premia Continuous.

If you become pregnant while taking Premia Continuous, tell your doctor immediately. Premia Continuous should not be taken while you are pregnant.

See your doctor at least every six months for a check-up. Some women will need to go more often.

Your doctor will:

  • Check your breasts;
  • Send you to have a mammogram;
  • Check your uterus and cervix;
  • Do a Pap smear;
  • Check your blood pressure.

Your doctor may also take blood to check your blood fats, sugar levels and liver function. This helps to monitor for unwanted effects of HRT.

If you have used Premia as HRT for 5 or more years, there may be a slight increase in the risk of you developing ovarian cancer.

See your doctor if you experience symptoms such as pressure, discomfort or pain in your stomach or pelvis; swollen or bloated stomach; appetite loss; changes in toilet habits (e.g. constipation, diarrhoea, passing urine more frequently, increased flatulence); heartburn and nausea; tiredness; unexplained weight loss or weight gain especially if these symptoms are new for you or continue for a few weeks. Having these symptoms does not necessarily mean you have ovarian cancer, but it is best to have a checkup. Your doctor will physically check your pelvic organs and conduct blood tests, to rule out ovarian cancer.

If you need to have blood tests tell the doctor that you are taking Premia Continuous. Premia Continuous can affect the results of some tests. These include hormone and liver function tests.

Check your breasts regularly. Your doctor or nurse can show you how to check your breasts properly. If you notice any changes to your breasts, see your doctor.

Include foods that are good sources of calcium and Vitamin D in your daily diet, and exercise regularly. Calcium, Vitamin D and exercise may help prevent thinning of the bones. Your doctor can advise you on which foods and types of exercise are best for you.

Tell your doctor well in advance (at least 4 to 6 weeks) of any expected hospitalisation or surgery.

If you go to the hospital unexpectedly, tell the doctor who admits you that you are taking Premia Continuous.

The risk of developing blood clots in your blood vessels may be temporarily increased as a result of an operation, serious injury or having to stay in bed for a prolonged period.

Tell your doctor if you have any breakthrough bleeding or spotting, which persists after 2 to 3 months of treatment with Premia Continuous. Breakthrough bleeding or spotting may occur during the first few months of treatment and then stop. However, if the bleeding continues your doctor may wish to check why it is happening.

Things you must not do

Do not take Premia Continuous to treat any other complaints unless your doctor tells you to.

Do not give your medicine to anyone else, even if they have the same condition as you.

Do not stop taking Premia Continuous without checking with your doctor.

After taking Premia Continuous

Storage

Keep your tablets in the blister pack until it is time to take them. If you take them out of the blister, they may not keep well.

Keep your tablets in a cool dry place where the temperature stays below 25°C. Do not store Premia Continuous, or any medicine, in a bathroom or near a sink. Do not leave Premia Continuous in the car or on windowsills. Heat and dampness can destroy some medicines.

Keep it where children cannot reach it. A locked cupboard at least one-and-a-half metres above the ground is a good place to store medicines.
