Gemcitabine is a type of chemotherapy drug. You might have it as a treatment for a number of different cancers, including bladder and breast cancer.
How gemcitabine works
Gemcitabine destroys quickly dividing cells, such as cancer cells.
How you have gemcitabine
You have gemcitabine into your bloodstream. It takes about 30 minutes.
You have the treatment through a drip into your arm or hand. 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.
When you have gemcitabine
You might have gemcitabine once a week for 2 or 3 weeks. And then have a week or 2 with no treatment to allow the body to recover.
The exact number of cycles and how long the cycle is depends on your cancer type.
You have blood tests before 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.
We haven't listed all the side effects. It's very unlikely that you will have all of these side effects, but you might have some of them at the same time.
How often and how severe the side effects are can vary from person to person. They also depend on what other treatments you're having. For example, your side effects could be worse if you're also having other drugs or radiotherapy.
When to contact your team
Your doctor, nurse or pharmacist will go through the possible side effects. They will monitor you closely during treatment and check how you are at your appointments. Contact your advice line as soon as possible if:
- you have severe side effects
- your side effects aren’t getting any better
- your side effects are getting worse
Early treatment can help manage side effects better.
Common side effects
Each of these effects happens in more than 1 in 10 people (10%). You might have one or more of them. They include:
Increased risk of getting an infection
Increased risk of getting an infection is due to a drop in white blood cells. Symptoms include a change in temperature, aching muscles, headaches, feeling cold and shivery and generally unwell. You might have other symptoms depending on where the infection is.
Infections can sometimes be life threatening. You should contact your advice line urgently if you think you have an infection.
Breathlessness and looking pale
You might be breathless and look pale due to a drop in red blood cells. This is called anaemia.
Bruising, bleeding gums or nosebleeds
This is due to a drop in the number of platelets in your blood. These blood cells help the blood to clot when we cut ourselves. You may have nosebleeds or bleeding gums after brushing your teeth. Or you may have lots of tiny red spots or bruises on your arms or legs (known as petechia).
Feeling or being sick
Feeling or being sick is usually well controlled with anti sickness medicines. Avoiding fatty or fried foods, eating small meals and snacks, drinking plenty of water, and relaxation techniques, can all help.
It is important to take anti sickness medicines as prescribed even if you don’t feel sick. It is easier to prevent sickness rather than treating it once it has started.
You might have liver changes that are usually mild and unlikely to cause symptoms. They usually go back to normal when treatment finishes. You have regular blood tests to check for any changes in the way your liver is working.
Flu like symptoms
This can happen a few hours after treatment. It may include headaches, muscle aches (myalgia), a high temperature and shivering. Taking paracetamol every 6 to 8 hours can help.
Swelling in the face, hands and feet
This usually goes away on its own, but tell your doctor or nurse if you have it.
You may have difficulty breathing with wheezing and coughing. Let your doctor or nurse know straight away if this happens.
Blood and protein in your urine
Small amounts of blood and protein in your urine may be found when your nurse tests your urine. This is not harmful.
Skin problems include a skin rash, dry skin and itching. This usually goes back to normal when your treatment finishes. Your nurse will tell you what products you can use on your skin to help.
You could lose all your hair. This includes your eyelashes, eyebrows, underarm, leg and sometimes pubic hair. Your hair will usually grow back once treatment has finished but it is likely to be softer. It may grow back a different colour or be curlier than before.
Occasional side effects
Each of these effects happens in more than 1 in 100 people (1%). You might have one or more of them. They include:
- difficulty sleeping
- a sore mouth or mouth ulcers
- loss of appetite
- itchy skin
- a cough
- back or muscle pain
- a runny nose
- tiredness and weakness (fatigue) during and after treatment
Rare side effects
Each of these effects happens in fewer than 1 in 100 people (1%). You might have one or more of them. They include:
- kidney changes that are usually mild and go back to normal after treatment
- lung scarring that can cause shortness of breath and a dry cough
- an irregular heart beat or heart muscle changes

What else do I need to know
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.
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're having treatment and for a few months afterwards. Talk to your doctor or nurse about effective contraception before starting treatment.
Don’t breastfeed during this treatment because the drug may come through into your breast milk.
You may not be able to become pregnant or father a child after treatment with this drugs. Talk to your doctor before starting treatment if you think you may want to have a baby in the future.
Men might be able to store sperm before starting treatment. And women might be able to store eggs or ovarian tissue. But these services are not available in every hospital, so you would need to ask your doctor about this.
Treatment for other conditions
Always tell other doctors, nurses, pharmacists or dentists that you’re having this treatment if you need treatment for anything else, including teeth problems.
Don’t have immunisations with live vaccines while you’re having treatment and for up to 12 months afterwards. The length of time depends on the treatment you are having. Ask your doctor or pharmacist how long you should avoid live vaccinations.
In the UK, live vaccines include rubella, mumps, measles, BCG, yellow fever and the shingles vaccine (Zostavax).
- have other vaccines, but they might not give you as much protection as usual
- have the flu vaccine (as an injection)
Contact with others who have had immunisations - You can be in contact with other people who have had live vaccines as injections. Avoid close contact with people who have recently had live vaccines taken by mouth (oral vaccines) such as the oral typhoid vaccine.
If your immune system is severely weakened, you should avoid contact with children who have had the flu vaccine as a nasal spray. This is for 2 weeks following their vaccination.
Babies have the live rotavirus vaccine. The virus is in the baby’s poo for about 2 weeks and could make you ill if your immunity is low. Get someone else to change their nappies during this time if you can. If this isn't possible, wash your hands well after changing their nappy.
Some brands of this drug contain alcohol (equal to half a glass of wine or half a pint of beer) and may make you drowsy or dizzy, especially if you have drunk alcohol. Don't operate machinery or drive if you feel drowsy.
