Steroids for brain tumours
Following a brain tumour diagnosis, it’s likely that you’ll be given steroids at some point during your treatment. These don’t treat the brain tumour itself, but could help to manage its side-effects.
Short summary
The steroids used for brain tumour treatment are called corticosteroids. These are NOT anabolic steroids, which are used by some athletes to build muscle.
Steroids for brain tumours are designed to reduce swelling in and around a tumour. This doesn’t help to treat the tumour itself, but might help with its symptoms or side effects.

Our Step by Step interactive guide outlines what happens following a diagnosis, to answer your questions and help you to understand what to expect.
Monitor your side-effects
Steroids, like any medication, can cause a variety of side-effects. But if you experience any, you should talk to your doctor. Use BRIAN’s quality-of-life tracker to record and monitor them, then share this with your healthcare team so they can support you.
What are steroids?
Steroids are hormones that are produced naturally in our bodies in small amounts. They help to control swelling when our body is injured.
Sometimes our bodies don’t produce enough to reduce the swelling. Fortunately, steroids created in a laboratory for medical purposes can be given in these cases.
How do steroids help brain tumours?
Brain cells in and around a tumour, or the area treated by surgery or radiotherapy, can swell and put pressure on surrounding tissues. This can cause symptoms, such as headaches and seizures.
Steroids help with symptom management rather than treating the tumour itself. So, you may be given them after diagnosis, or before or after these treatments to reduce the swelling and relieve those symptoms.
You may also be given a low dosage of steroids if you’re having chemotherapy or radiotherapy and feeling sick.
Before being given steroids for a brain tumour
Your healthcare team will talk through what will happen and discuss any potential side-effects with you before any steroids are given.
This is your chance to ask any questions. Remember, no question is a silly question.
It can also help to find out who you should contact and how to reach them if you have any questions or concerns at a later time.
While taking steroids for a brain tumour
The steroid most commonly used with brain tumours is dexamethasone. They are fast-acting drugs, so the effects caused by the tumour can reduce quite quickly. They may need to be taken at set times of day.
They can be taken as:
-
Tablets are the most common way to take steroids. If you have difficulty swallowing tablets, try practising with tic tacs®.
The colour and dosage of the tablet/medicine will depend on which one you’ve been prescribed.
-
Steroids are only likely to be given by injection when you’re in hospital or if you’re unable to take tablets by mouth.
How long can you take steroids for a brain tumour?
Steroids’ side-effects usually appear over the long term. So, because of this, steroids are mostly given for a limited time and stopped before the side-effects can appear. Steroids are usually prescribed for a short period ranging from a few days to a few weeks.
That being said, if the person affected by a brain tumour has a short to medium term prognosis, steroids can be prescribed for longer. This is because the side-effects likely wouldn’t arise during their life expectancy. But, your medical team will discuss this with you based on your prognosis.
You should never suddenly stop taking steroids or reduce your dosage without guidance from your medical team. This can make you very unwell.
Jennifer talks about using steroids during her brain tumour treatment.
Arvin Kaushal, diagnosed with 6 germinomas in 2015
“One minute I was an ambitious young man enjoying life, the next I was diagnosed with six brain tumours and having aggressive radiotherapy. The fluid in my brain also became blocked, so I was given steroids.
“I put on seven stone, became depressed and didn’t want to go out. Then I was diagnosed with diabetes insipidus and a fatty liver and told to lose weight.
“This was a turning point. I didn’t want any more health problems so, after being given a smartwatch, I was on a mission.
“I walked around the kitchen while I made breakfast, or did half an hour on a treadmill in front of the TV. I then walked into town with mum, resting at bus stops, and walked with dad to reach 10,000 steps each day. Eventually my physiotherapist said I could lift weights to burn fat.
“It took two years, but I’m down to my old weight!
“I still have fatigue and dizziness, but my next goals are to go back to work and do a 5km run.
“I’m proud I’ve lost weight and so grateful for my family’s support.”

After taking steroids
As with many medications, steroids affect different people in different ways. Their effect will also depend on the exact type and dosage prescribed for you. Talk to your healthcare team about any side-effects you experience.
At the end of your treatment, your specialist is likely to reduce your dosage gradually.
This is because, after taking steroids for a few days, your body will be producing less of its own natural steroids. Reducing the dosage of your medical steroids allows your body to start producing its own again.
Please remember that you should never stop taking your steroids suddenly or reduce your dosage unless your specialist advises you to. It can make you very unwell.
Always make sure you have enough tablets on repeat prescription, by talking to your GP.
If steroids don’t work
Although treatment plans are carefully developed by healthcare professionals to be as effective as possible while having the fewest risks or side-effects, sometimes steroids might not work.
This can be worrying, but just because one treatment hasn’t worked, it doesn’t mean others won’t.
