Ulipristal acetate for uterine fibroids

About ulipristal acetate for uterine fibroids

Ulipristal acetate works by blocking the effects of the female hormone progesterone. There are two brands of ulipristal acetate tablets available. The two brands of tablet have different uses and contain different amounts of ulipristal acetate. Low-strength tablets (Esmya® brand containing 5 mg ulipristal acetate) are used to treat heavy or painful periods caused by uterine fibroids. This leaflet discusses ulipristal acetate when it is prescribed for this purpose. More information is available about the higher strength of ulipristal acetate tablet (EllaOne® brand) in the medicine leaflet called Emergency hormonal contraception.

Fibroids (which are also known as myomas) are non-cancerous growths in the womb (uterus). They can sometimes cause heavy or painful periods, tummy swelling and urinary problems. Surgery is the most common treatment for fibroids which cause symptoms. Ulipristal acetate is prescribed to reduce the size of the fibroids before the surgery.

The female hormone progesterone is thought to play a role in the development of fibroids. Ulipristal acetate works by blocking the effects of progesterone. This stops the fibroids from growing and they shrink in size.

Some medicines are not suitable for people with certain conditions, and sometimes a medicine may only be used if extra care is taken. For these reasons, before you start taking ulipristal acetate for uterine fibroids it is important that your doctor knows:

• Om du är gravid eller ammar.

• If you have severe asthma.

• If you have any problems with the way your liver works, or any problems with the way your kidneys work.

• If you have breast cancer, or cancer of the womb (uterus), neck of the womb (cervix), or ovaries.

• Om du någonsin har haft en allergisk reaktion mot en medicin.

• Om du tar några andra läkemedel. Detta inkluderar alla läkemedel du tar som finns att köpa utan recept, samt växtbaserade och komplementära läkemedel.

• Before you start the treatment, read the manufacturer's printed information leaflet from inside the pack. It will give you more information about ulipristal acetate and will provide you with a full list of the side-effects which you may experience from taking it.

• Take ulipristal acetate exactly as your doctor tells you to. You will be asked to start taking the tablets during a week you are having a period. Continue to take one 5 mg tablet each day. You will be prescribed the tablets for a maximum of four months, possibly on two occasions.

• You can take ulipristal acetate tablets before or after food. Swallow the tablets with a drink of water.

• If you forget to take a dose, take it as soon as you remember unless you are more than 12 hours late. If you are more than 12 hours late, leave out the forgotten dose and take your next tablet at the usual time. Do not take two tablets together to make up for a missed dose.

• Försök att hålla dina regelbundna möten med din läkare. Detta är så att din läkare kan följa upp din utveckling.

• You should avoid getting pregnant both while you are taking ulipristal acetate and for at least 12 days after stopping taking it. Please use a barrier method of contraception (such as a condom), as hormonal methods of contraception are not suitable with ulipristal acetate. If you need further contraceptive advice, please speak with your doctor.

• Do not drink grapefruit juice while you are on ulipristal acetate. This is because a chemical in grapefruit juice can increase the amount of ulipristal acetate in your bloodstream. This could make side-effects more likely.

Along with their useful effects, most medicines can cause unwanted side-effects although not everyone experiences them.

The unwanted effects often improve as your body adjusts to the new medicine but speak with your doctor or pharmacist if any of the following continue or become troublesome.

If you experience any other symptoms which you think may be due to the tablets, please speak with your doctor or pharmacist for further advice.
