Enzyme replacement for Gaucher disease
Velaglucerase
A regular drip that replaces the missing enzyme in Gaucher disease, an alternative enzyme replacement to imiglucerase.
What is Velaglucerase?
Velaglucerase is an enzyme replacement therapy for Gaucher disease, an inherited condition in which a fatty substance builds up because an enzyme is missing, affecting the spleen, liver, bones and blood counts. It works in much the same way as imiglucerase and is given as a slow drip into a vein, usually every couple of weeks and for life, at a specialist metabolic centre. It does not cure Gaucher disease but helps control it. The most common issue is an infusion reaction, managed with pre-medication and by slowing the drip.
Education and reference only. This is a plain-language guide to Velaglucerase — it deliberately contains no doses. Doses depend on the person, the brand and the reason for treatment, and belong with your prescriber. Always check the BNF, the product labelling (SmPC) and follow medical advice.
What it is
Velaglucerase is a man-made version of glucocerebrosidase, the enzyme that people with Gaucher disease lack. It is another enzyme replacement treatment for Gaucher disease, used as an alternative to imiglucerase. Gaucher disease is a rare inherited 'lysosomal storage' disorder, in which a fatty substance that should be broken down builds up in cells, especially in the spleen, liver and bone marrow, causing an enlarged spleen and liver, low blood counts, tiredness and bone problems. Velaglucerase (brand name VPRIV) is given as a drip into a vein, started and supervised by a specialist metabolic team.
How it works
Velaglucerase supplies the working enzyme that people with Gaucher disease are missing, so the fatty substance building up in cells can be broken down. Given regularly into a vein, it helps clear deposits from the spleen, liver and bone marrow, which can shrink an enlarged spleen and liver, improve blood counts and ease bone problems over time. It works in much the same way as imiglucerase, and because the body keeps producing the fatty substance, the enzyme must be replaced repeatedly, so treatment is lifelong.

Practical use
How to take Velaglucerase
General, dose-free guidance — always follow your prescriber's and the leaflet's specific instructions.
- It is given as a slow drip into a vein at a specialist centre, usually every couple of weeks, by trained staff.
- You may be offered pre-medication to reduce the chance of an infusion reaction, depending on how you respond.
- Tell the staff at once if you feel flushed, feverish, shivery, sick or short of breath during the drip.
- Keep your regular appointments, as missing infusions lets the fatty substance build up again.
- If you become stable, the team may train you to have the drip at home, but only once they agree.
Weighing it up
Advantages & disadvantages of Velaglucerase
Advantages
- Replaces the missing enzyme and can shrink an enlarged spleen and liver and improve blood counts.
- Provides an alternative to imiglucerase, which is helpful if that is not suitable or available.
- Often improves tiredness and can ease bone problems over time.
Disadvantages
- Does not cure Gaucher disease and must be given by drip for life.
- Can cause infusion reactions needing pre-medication and monitoring.
- Bone changes may improve more slowly than blood and organ measures.
Practical use
Good to know
Velaglucerase controls Gaucher disease but does not cure it, so the drips continue for life and are arranged through a specialist metabolic centre. It is an alternative to imiglucerase, and the team chooses between them based on individual factors and supply. Many people see their spleen and liver shrink, their blood counts improve and their energy return over months and years. The most common issue is an infusion reaction, with flushing, fever, chills, headache or feeling sick during or soon after the drip; pre-medication and a slower rate often help. Some people make antibodies to the enzyme, which the team monitors. Once stable, some people are trained to have their infusions at home.
Who should not take it / use with caution
- People who have had a severe allergic reaction to velaglucerase should not receive it again unless specialists advise.
- It is used with extra care in those who have developed antibodies affecting its action or reactions.
- Other health conditions, pregnancy or breastfeeding should be discussed with the metabolic team.
Monitoring
- Regular checks of the size of the spleen and liver, blood counts and bone health to track response.
- Watching for infusion reactions during and after each drip and for antibodies over time.
- Ongoing specialist review to adjust treatment and decide whether home infusions are suitable.
Side effects
- Infusion reactions such as flushing, fever, chills, headache, nausea or tiredness are the most common.
- Less commonly, dizziness, a fast heartbeat, back pain or a rash during or after the drip.
- Rarely, a serious allergic reaction, which is why infusions are given where staff can respond quickly.
Key interactions
- No major routine medicine interactions are well established, but tell the team everything you take.
- Treatments for related problems, such as low blood counts or bone disease, are coordinated by the centre.
- Any new medicines should be mentioned so they can be reviewed alongside the infusions.
Available as: A drip (infusion) into a vein, given at a specialist centre or sometimes at home.
Answers
Velaglucerase: frequently asked questions
How is velaglucerase different from imiglucerase?
Both are enzyme replacement treatments for Gaucher disease that work in much the same way; velaglucerase is an alternative your team may choose based on your needs and supply.
Will it cure my Gaucher disease?
No. It helps control the disease by replacing the missing enzyme, but it does not cure it, so the drips are needed for life.
Why do I feel unwell during the drip?
Infusion reactions such as flushing, fever or nausea are common; pre-medication and slowing the rate usually help settle them.
How often will I need it?
It is usually given every couple of weeks at a specialist centre, though your team will confirm the schedule that suits you.
Can I switch between the two Gaucher drugs?
Your specialist team may switch you between enzyme replacements if needed, for example because of supply or how you respond.
