A doctor will review your order and write you a prescription, if appropriate. This prescription is then forwarded to a pharmacy. The pharmacy will have your medicine delivered to you within one to three working days. Read more about this process here.
Menopause is a natural reaction in your body when your ovaries stop producing eggs. When working during child-bearing years, your ovaries produce the hormone oestrogen, as your ovaries stop working, so the levels of oestrogen in your blood drop. This is not something that happens suddenly overnight, in fact, it can take years, lasting anything from 6 months to 13 years. Sadly, if you experience unpleasant symptoms as you are going through the menopause you may suffer for some time.
Menopause usually happens sometime between the ages of 45 and 55. In the UK the average age to reach menopause is 51. It can happen much earlier though and this is known as premature menopause. Premature menopause can happen at any age and there is no clear cause as to why it happens. Sometimes it can be caused by surgery to remove the ovaries, but in other cases, it’s simply unexplained.
There are three stages of menopause:
- Perimenopause – the time when your periods are becoming less frequent and lighter, lasts on average 4 years.
- Menopause – Once your last period finishes, the average age in the UK is 51.
- Postmenopause – menopause ends one full year after your last period but it usually takes 2 to 5 years for symptoms to stop.
This drop in oestrogen levels can leave you more susceptible to certain types of disease, like osteoporosis. This is why it’s really important to take care of your health during the menopause, stay active, eat a healthy varied diet, lose any excess weight, stop smoking and limit your alcohol intake.
The changes in your hormones during all of these various stages of menopause can cause some unpleasant symptoms including:
- hot flushes
- vaginal dryness
- lower sex drive
- night sweats
- difficulty sleeping
- mood changes
- joint pain or stiffness
- frequent urinary tract infections
- reduced muscle mass
- weak bones, osteoporosis
There are plenty of things you can do at home to help ease the symptoms of menopause, for example, maintaining an active, healthy lifestyle. Regular exercise (30 minutes of moderate exercise, 5 times a week) can help you to sleep better and improve your mood. Pelvic floor exercise can help with bladder control as you strengthen the muscles required. If you are suffering from hot flushes take steps to help prevent these like avoiding possible triggers: spicy foods, caffeine, alcohol etc. Try to keep as cool as possible and dress in layers so you can remove some clothing if you start to feel too warm. If you aren’t coping well at home then you may wish to speak to a doctor about medical treatments. The main treatment for menopause is Hormone Replacement Therapy, which restores the normal levels of oestrogen and progesterone in your blood. There are other remedies out there, such as complementary and herbal medicines or bioidentical hormone therapy, but it is unclear how effective or safe these are, as they are not tested in the same way as conventional medicines.
You can also look at topical treatments for vaginal dryness or cognitive behavioural therapy to help with low mood.
Hormone Replacement Therapy comes in different guises, you can take a combination of oestrogen and progesterone or just oestrogen. Getting the right type for you can be a process of trial and error. Hormone Replacement Therapy also comes in different forms – tables, patches, vaginal creams, gels, pessaries and rings. Not all HRT treatments are taken the same way, some are taken continuously others alter along with your menstrual cycle. One option you can consider it Premarin, a Hormone Replacement Therapy which contains only oestrogen, see below for more information.
What is Premarin?
Premarin is a Hormone Replacement Therapy to help you with the symptoms of menopause. It contains the hormone oestrogen. When you are going through the menopause oestrogen levels in your blood drop as you stop having your periods. This drop can cause some unpleasant symptoms like hot flushes, lower sex drive, vaginal dryness, mood swings and difficulty sleeping.
Many women cope with these symptoms on their own, but when they are severe HRT can help to ease them so you can get back to enjoying life: the levels of oestrogen are balanced by the therapy. Premarin contains only oestrogen. Lower levels of oestrogen also put you at risk for diseases like osteoporosis.
When is Premarin used?
Premarin is prescribed for women going through the menopause who are experiencing severe symptoms. Premarin is usually only prescribed to women who no longer have a womb as it contains only oestrogen. However, women who have not had their womb removed can still be prescribed Premarin. There may be circumstances where it is prescribed alongside another treatment which contain progesterone.
Premarin is used to:
- Combat moderate to severe hot flushes;
- Treat menopausal changes in and around the vagina;
- Ward off osteoporosis.
Premarin can also be used to treat conditions where a woman’s ovaries do not produce enough oestrogen naturally and to treat the symptoms of certain cancers in both men and women.
How do you use Premarin?
When it comes to taking medication, you should always follow the instructions given to you by your doctor or pharmacist. Premarin comes in tablet form and should be swallowed whole. If you crush or split the tablet it may affect the way Premarin works. You can take Premarin with or without food.
What are the dosages?
The usual dose to treat menopausal symptoms is one tablet a day. There are different doses available and you should take the lowest dose to control your symptoms. The lowest dose is 0.3mg and this should be your starting dose the first time you use Premarin. If after time this does not seem to control your symptoms then you may need a larger dose.
Below is a list of the various dosages available for Premarin tablets, each tablet strength is colour coded to help you recognise it easily:
- 0.3mg - green coloured tablet
- 0.45mg – blue coloured tablet
- 0.625mg - maroon coloured tablet
- 0.9mg - white coloured tablet
- 1.25mg – yellow coloured tablet
Take your tablet at the same time every day. You take Premarin every single day, unlike some HRTs, there are no tablet-free days when taking Premarin.
If you are not already taking some kind of HRT or you are taking an HRT that does not give you a monthly bleed you can start your course of Premarin at any time. If you are already taking an HRT that gives you a monthly bleed then you will need to wait until you finish the course of the treatment you are already on and start with Premarin the day after. For osteoporosis, the recommended dose is 0.625 mg a day, but you may be prescribed up to 1.25mg a day. If you forget to take a tablet, take the missed tablet as soon as possible but don’t take a double dose. If you miss a tablet you may experience light bleeding. If you do take a double dose you may feel sick or have tender breasts and be dizzy but it is unlikely to cause any serious harm.
What are the side effects of Premarin?
