Read about CVP, how you have it and other important information about having this chemotherapy. 

CVP is the name of a combination of chemotherapy. It is a treatment for low grade non Hodgkin lymphoma. It is made up of the drugs:

  • C – cyclophosphamide
  • V – vincristine (also known as Oncovin)
  • P – prednisolone, which is a steroid

How you have it

Cyclophosphamide and vincristine are clear fluids. You have them into your bloodstream (intravenously).

You have prednisolone as tablets. You need to swallow them after a meal, or with milk, as they can cause stomach irritation. Your doctor will advise you which dose you need to take. It is best to take prednisolone early in the day, preferably after breakfast.

Into your bloodstream

You have the treatment through a drip into your arm. A nurse puts a small tube (a cannula) into one of your veins and connects the drip to it.

You might need a central line. This is a long plastic tube that gives the drugs into a large vein, either in your chest or through a vein in your arm. It stays in while you’re having treatment, which may be for a few months.

Taking your tablets or capsules

You must take tablets and capsules according to the instructions your doctor or pharmacist gives you.

Whether you have a full or empty stomach can affect how much of a drug gets into your bloodstream.

You should take the right dose, not more or less.

Never stop taking a cancer drug without talking to your specialist first.

When you have it

You usually have chemotherapy as cycles of treatment. You may have between 6 and 8 cycles of CVP. Each cycle lasts 3 weeks, so it takes from 4 to 6 months.

You have each cycle of treatment in the following way. 

Day 1
  • cyclophosphamide and vincristine into a vein, takes about 30 minutes
  • prednisolone tablets
Days 2 to 5
  • prednisolone tablets

You can take the prednisolone tablets at home.

You then have no treatment for just over 2 weeks. The cycle then starts again.

Tests during treatment

You have blood tests before starting treatment and during your treatment. They check your levels of blood cells and other substances in the blood. They also check how well your liver and kidneys are working.

Side effects

Important information


Don’t have immunisations with live vaccines while you’re having treatment and for at least 6 months afterwards.

In the UK, live vaccines include rubella, mumps, measles, BCG, yellow fever and Zostavax (shingles vaccine).

You can:

  • have other vaccines, but they might not give you as much protection as usual
  • have the flu vaccine
  • be in contact with other people who've had live vaccines as injections

Avoid contact with people who’ve had live vaccines taken by mouth (oral vaccines). This includes the rotavirus vaccine given to babies. The virus is in the baby’s urine for up to 2 weeks and can make you ill. So, you mustn't change their nappies for 2 weeks after their vaccination.

You also need to avoid anyone who has had oral polio or typhoid vaccination recently.

Loss of fertility

You may not be able to become pregnant or father a child after treatment with this drug. Talk to your doctor before starting treatment if you think you may want to have a baby in the future. Men may be able to store sperm before starting treatment. Women may be able to store eggs or ovarian tissue but this is rare.

Treatment for other conditions

Always tell other doctors, nurses or dentists that you’re having this treatment if you need treatment for anything else, including teeth problems.


Don’t breastfeed during this treatment because the drug may come through in your breast milk.

Pregnancy and contraception

This treatment might harm a baby developing in the womb. It is important not to become pregnant or father a child while you are having treatment and for a few months afterwards. Talk to your doctor or nurse about effective contraception before starting treatment.

Other medicines, foods and drink

Cancer drugs can interact with some other medicines and herbal products. Tell your doctor or pharmacist about any medicines you are taking. This includes vitamins, herbal supplements and over the counter remedies.
