Description

Premarin is a medicine containing a mixture of estrogen hormones. Premarin is the brand name of that medicine and belongs to a group of drugs known as hormone replacement therapy, or HRT.

It is used to treat moderate to severe hot flashes, changes in and around the vagina, and other symptoms of menopause or low amounts of estrogen (hypoestrogenism). This medicine is also used to prevent osteoporosis (thinning of the bones) after menopause.

During menopause, your body produces less estrogen. This can cause symptoms such as "hot flashes" or dryness of the vagina. Premarin works like the hormones produced by the ovaries before menopause. When given during or after menopause, it can help control the symptoms.

Premarin can also be used to treat women before menopause if their ovaries do not make enough estrogen naturally.

How should you take Premarin (Conjugated estrogens)?

Follow all directions on your prescription label and read all medication guides or instruction sheets. Take Premarin exactly as directed.

The usual dose is one tablet every day.

Your doctor will aim to give you the lowest dose for the shortest time to treat your symptoms as necessary while minimizing the risk of side effects.

Take your tablet at the same time each day as this will help you remember to take your medicine.

If you are not already taking a HRT product or if you are taking an HRT product that does not give you a monthly bleed you may start your Premarin at any convenient time.

If you are changing from an HRT product that gives you a monthly bleed, start Premarin the day after you finish the course of the previous product, unless instructed otherwise by your doctor.

If you forget to take a tablet, take it as soon as you remember and then carry on taking the remaining tablets at the usual time. Do not take a double dose to make up for a forgotten tablet.

Missed tablets may cause a short period of light bleeding in women who have not had a hysterectomy.
