PREMARIN is a type of treatment called hormone replacement therapy (HRT) and contains the hormone oestrogen in the form known as conjugated oestrogens.

PREMARIN helps to relieve the discomfort many women feel during and after menopause, including symptoms such as "hot flushes", sweating and vaginal dryness. It helps to prevent thinning of the bones (osteoporosis), which can cause fractures.

PREMARIN is also used to treat women where either the ovary does not function properly or has been removed.

If your doctor thinks you will need to take oestrogens for a long time,

including for the prevention of osteoporosis, he or she will have considered the benefits and risks of other treatments before prescribing PREMARIN for you.

How it works

Menopause occurs naturally in women, typically between the ages of 45 and 55. During menopause, your body produces less oestrogen than it did beforehand. This can cause symptoms such as "hot flushes". 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 making them weaker and more likely to break, especially the bones of the spine, hip and wrist.

Conjugated oestrogens are like the hormones produced by the ovaries before menopause. When given during or after menopause, they can help control the symptoms.

Oestrogen is used treat women who have had their uterus or "womb" removed. If you have not had your uterus or "womb" removed, you will need to take an oestrogen with a progestogen.

Ask your doctor if you have any questions why PREMARIN has been prescribed for you.

Your doctor may have prescribed PREMARIN for another use.

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

PREMARIN is not habit-forming.

PREMARIN 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. 

  1. How to take it

    Swallow tablets whole with a full glass of water. Do not divide, crushed, chew, or dissolve the tablet in your mouth.

    When to take PREMARIN

    If you are not already using any type of HRT you can start PREMARIN on

any convenient day. However, it is recommended you start PREMARIN after your last period. If you do not have predictable periods, then start PREMARIN on a Monday as this matches the directions on the calendar pack.

If you are already using a different type of HRT, your doctor can advise you when to start PREMARIN.

It does not matter if you take PREMARIN before or after food.

How much to take

For symptoms of menopause and prevention of osteoporosis, take one tablet daily.

For women with a uterus, your doctor will also prescribe a progestogen tablet to be taken with your PREMARIN. For some women with a history of endometriosis, who have had a hysterectomy, a progestogen may also be needed. Your doctor will advise you.

For women without fully-functioning ovaries, your doctor will prescribe PREMARIN according to your needs. The dose may be higher or lower than that prescribed for the treatment of menopause symptoms.

Take all tablets in a blister pack before starting a new pack.

How long to take it

Continue to take your medicine for as long as your doctor tells you.

Your doctor can discuss the risks and benefits of long-term treatment with HRT in your particular case.

If you forget to take your tablets

If less than 12 hours has passed from the time you normally take PREMARIN, take the missed tablet.

Take the next tablet at the usual time.

If more than 12 hours has passed, discard the missed tablet and take the next tablet when you normally would.

Do not take a double dose to make up for the one you missed.

If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.

If you take too much (Overdose)

Immediately telephone your doctor or the Poisons Information Centre (telephone: 0800 POISON or 0800 764 766) or go to Accident and Emergency at the nearest hospital if you think you or anybody else has taken too much PREMARIN.

Do this even if there are no signs of discomfort or poisoning.

You may need urgent medical attention.

Symptoms of an overdose may include:

? feeling sick or vomiting ? dizziness
? feeling sleepy or tired
? breast tenderness

? stomach pain
? women may also experience

menstrual bleeding.

Some women may need to go more often.

Your doctor will at regular intervals:

  • ?  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 any unwanted effects of HRT.

    If you need to have blood tests tell the doctor that you are taking PREMARIN.

    PREMARIN 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.

    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.

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

    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 PREMARIN.

    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.

    Tell your doctor or pharmacist if you are taking any of the following:

  • ?  some medicines for epilepsy such as phenytoin, phenobarbitone and carbamazepine

  • ?  some antibiotics and anti- infectives such as rifampicin, erythromycin and clarithromycin

  • ?  thyroid replacement therapy

  • ?  corticosteroids, such as


  • ?  ritonavir for the treatment of HIV infection

  • ?  cyclosporin used to prevent organ rejection.

    Grapefruit juice may also affect how well PREMARIN works.

    If you have not told your doctor about any of the above, tell them before you start taking PREMARIN.
