I have been diagnosed with hyperprolactinaemia: what are the next steps?

Being diagnosed with hyperprolactinaemia is the first step to working out what is causing your symptoms. In this article we will look at what these treatments are, how long they take to work and share where you can find more information.

Do all people with hyperprolactinaemia need treatment?

Some people with hyperprolactinaemia may not need treatment if it is not causing any symptoms or impacting other bodily functions.1​​​​​​

What are the treatments for

When treatment is required, it depends on the cause.

Due to Medication
Your doctor may look into whether you can stop the medication you are taking or see if there is an alternative treatment that you can try.

Most of the time, the first option is medication to treat the high prolactin levels
Medications aim to reduce the production of prolactin which means stop your symptoms3
Medications are usually successful
If medications don’t work, then surgery or radiotherapy may be needed

How do I know if my hyperprolactinaemia medication is working?2

If you have been put on medication to treat your hyperprolactinaemia your doctor will usually get you to take a blood test 1 month after starting treatment. And at regular intervals after that.

Sometimes you may have a magnetic resonance imaging (MRI) scan up to a year after treatment.

After 2-3 years of starting your medicine, if your prolactin levels are normal, your doctor might look at slowly lowering the dose you take over a period of time.

Between 26-69% of people have their hyperprolacitnaemia return. This is usually in the first year of stopping treatment. This is why you will need to have regular blood tests to check your prolactin level.

If I have a pituitary tumour, do I have cancer?4

No, it is not cancer. This tumour is a lump of abnormal tissue. If they are left untreated, they can slowly grow in size but only very rarely do they spread to other parts of the body.
