What is GemCap?

GemCap is used to treat pancreatic cancer. It is best to read this information with our general information about chemotherapy and the type of cancer you have. GemCap is named after the chemotherapy drugs used:

Your doctor will talk to you about this treatment and its possible side effects before you agree (consent) to have treatment.


How GemCap is given

You will be given GemCap in the chemotherapy day unit. A chemotherapy nurse will give it to you.

During treatment you usually see a cancer doctor, a chemotherapy nurse or a specialist nurse, and a specialist pharmacist. This is who we mean when we mention doctor, nurse or pharmacist in this information.

Before or on the day of treatment, a nurse or person trained to take blood (phlebotomist) will take a blood sample from you. This is to check that your blood cells are at a safe level to have chemotherapy.

You will see a doctor or nurse before you have chemotherapy. They will ask you how you have been feeling. If your blood results are okay, the pharmacist will prepare your chemotherapy. Your nurse will tell you when your treatment is likely to be ready.

Your nurse usually gives you anti-sickness (anti-emetic) drugs before the chemotherapy. The gemcitabine can be given through:

  • a short thin tube the nurse puts into a vein in your arm or hand (cannula)
  • a fine tube that goes under the skin of your chest and into a vein close by (central line)
  • a fine tube that is put into a vein in your arm and goes up into a vein in your chest (PICC line).

Your nurse gives you gemcitabine as a drip (infusion) over 30 minutes. They usually give the drip through a pump, which gives you the treatment over a set time.

You will then be given your capecitabine tablets to take at home.

Your course of chemotherapy

You will have chemotherapy as a course of several sessions (or cycles) of treatment over a few months.

GemCap can be given in different ways. We give an example of one way below.

A 28 day (4 week) cycle

On the first day, you will have a gemcitabine drip (infusion) in the chemotherapy day unit. You will also start taking the capecitabine tablets at home. The tablets are taken every day for 21 days (3 weeks).

The gemcitabine infusion is repeated on days 8 and 15 of the cycle.

When you have finished the capecitabine tablets, you have 7 days without any chemotherapy before starting the next cycle of GemCap. This will be exactly the same as your first cycle.

Your doctor or nurse will talk to you about your treatment plan.

Taking your capecitabine tablets

Capecitabine is taken as tablets. The nurse or pharmacist gives you the capecitabine tablets to take at home. Always take your tablets exactly as you are told to. This is to make sure they work as well as possible for you.

You take capecitabine tablets twice a day. Swallow them whole with a glass of water within half an hour after eating a meal. Take the tablets in the morning after eating breakfast and then in the evening after your evening meal.

Tell your doctor if you find it difficult to swallow the tablets. They may suggest that you dissolve the capecitabine tablets in water. In this case, dissolve the tablets in a 200ml glass of warm water. Stir the water with a spoon until the tablets are completely dissolved and then drink it immediately. The glass and spoon should be washed and kept separate from your other crockery and cooking utensils.

If you forget to take a tablet, do not take a double dose. Keep to your regular schedule and let your doctor or nurse know.

Other things to remember about your tablets include:

  • Keep them in the original package and at room temperature, away from heat and direct sunlight.
  • Keep them safe and out of sight and reach of children.
  • If you are sick just after taking the tablets, contact the hospital. Do not take another dose.
  • If your treatment is stopped, return any unused tablets to the pharmacist.

About side effects

We explain the most common side effects of this treatment here. We also include some less common side effects. You may get some of the side effects we mention, but you are unlikely to get all of them.

You may also have some side effects that we have not listed here. Always tell your doctor, nurse or pharmacist about any side effects you have.

Your doctor can give you drugs to help control some side effects. It is important to take them exactly as your nurse or pharmacist explains. This means they will be more likely to work for you. Your nurse will give you advice about managing your side effects. After your treatment is over, most side effects start to improve.

Serious and life-threatening side effects

Some cancer treatments can cause severe side effects. Rarely, these may be life-threatening. Your cancer doctor or nurse can explain the risk of these side effects to you.

Rarely, capecitabine can cause severe side effects in people who have low levels of an enzyme called DPD. This is called having a DPD deficiency. You will not know before you start treatment whether you have a DPD deficiency as there are no symptoms. There is a test available but it only tests for the more common types of DPD deficiency. This means that the test will detect most cases of DPD deficiency but not all cases. The test is not widely available on the NHS. Talk to your doctor if you are worried about having a DPD deficiency.

Contact the hospital

Your nurse will give you telephone numbers for the hospital. If you feel unwell or need advice, you can call at any time of the day or night. Save these numbers in your phone or keep them somewhere safe.

Sometimes side effects can become serious very quickly. It is important to contact the hospital straight away if you have new symptoms or side effects.

More information

We cannot list every side effect for this treatment. There are some rare side effects that are not listed. You can visit the electronic Medicines Compendium (eMC) for more detailed information.

Side effects while given

Some people may have side effects while they are being given the chemotherapy or shortly after they have it:

Flu-like symptoms

Gemcitabine may cause flu-like symptoms such as:

  • feeling hot, cold or shivery
  • having a headache
  • aching.

You may have these symptoms while the drug is being given or several hours later. Your nurse will tell you if this is likely to happen. They may advise you to take paracetamol. Drinking plenty of fluids will also help.

Contact the hospital if:

  • your symptoms are severe
  • you have a fever
  • your symptoms do not improve after 24 hours.

Common side effects

Risk of infection

This treatment can reduce the number of white blood cells in your blood. These cells fight infection.

If the number of white blood cells is low, you are more likely to get an infection. A low white blood cell count is called neutropenia.

If you have an infection, it is important to treat it as soon as possible. Contact the hospital straight away on the 24-hour contact number you have if:

  • your temperature goes over 37.5°C (99.5°F)
  • you suddenly feel unwell, even with a normal temperature
  • you have symptoms of an infection.

Symptoms of an infection include:

  • feeling shivery
  • a sore throat
  • a cough
  • diarrhoea
  • needing to pass urine often.

It is important to follow any specific advice your cancer treatment team gives you.

The number of white blood cells will usually return to normal before your next treatment. You will have a blood test before having more treatment. If your white blood cell count is low, your doctor may delay your treatment for a short time.

Bruising and bleeding

This treatment can reduce the number of platelets in your blood. Platelets are cells that help the blood to clot. 

Tell your doctor if you have any bruising or bleeding that you cannot explain. This includes:

  • nosebleeds
  • bleeding gums
  • tiny red or purple spots on the skin that may look like a rash.

Some people may need a drip to give them extra platelets. This is called a platelet transfusion.

Anaemia (low number of red blood cells)

This treatment can reduce the number of red blood cells in your blood. These cells carry oxygen around the body. If the number of red blood cells is low, you may be tired and breathless. Tell your doctor or nurse if you feel like this. If you are very anaemic, you may need a drip to give you extra red blood cells. This is called a blood transfusion.

Feeling sick

You may feel sick in the first few days after this treatment. Your doctor will give you anti-sickness drugs to help prevent or control sickness. Take the drugs exactly as your nurse or pharmacist tells you. It is easier to prevent sickness than to treat it after it has started.

If you feel sick, take small sips of fluids and eat small amounts often. If you continue to feel sick, or if you vomit more than once in 24-hours, contact the hospital as soon as possible. They will give you advice and may change the anti-sickness drug to one that works better for you.

Sore mouth

You may get a sore mouth or mouth ulcers. This can make you more likely to get a mouth infection.

Use a soft toothbrush to clean your teeth or dentures in the morning, at night and after meals.

If your mouth is sore:

  • tell your nurse or doctor – they can give you a mouthwash or medicines to help
  • try to drink plenty of fluids
  • avoid alcohol, tobacco, and foods that irritate your mouth.

Loss of appetite

This treatment can affect your appetite. Do not worry if you do not eat much for a day or two. But if your appetite does not come back after a few days, tell your nurse or dietitian. They will give you advice. They may give you food or drink supplements.

Feeling tired

Feeling tired is a common side effect. It is often worse towards the end of treatment and for some weeks after it has finished. Try to pace yourself and plan your day so you have time to rest. Gentle exercise, like short walks, can give you more energy. If you feel sleepy, do not drive or operate machinery.

Diarrhoea

Capecitabine may cause diarrhoea. This can be severe. Your nurse or doctor may give you anti-diarrhoea drugs to take at home.

If you have diarrhoea:

  • follow any advice you have been given about taking anti-diarrhoea drugs
  • drink at least 2 litres (3½ pints) of fluids each day
  • avoid alcohol, caffeine, milk products, high-fat foods and high-fibre foods.

Contact the hospital straight away if:

  • you have diarrhoea at night
  • you have diarrhoea more than 6 times in a day
  • the anti-diarrhoea drugs do not work within 24 hours.

Your doctor may ask you to stop taking capecitabine. When the diarrhoea is better, they will tell you if you can start taking it again. Sometimes the dose is reduced.

Constipation

This treatment can cause constipation. Here are some tips that may help:

  • Drink at least 2 litres (3½ pints) of fluids each day.
  • Eat high-fibre foods, such as fruit, vegetables and wholemeal bread unless there are any restrictions on what you eat.
  • Do regular gentle exercise, like going for short walks.

If you have constipation, contact the hospital for advice. Your doctor can give you drugs called laxatives to help.

Tummy pain

You may get pain or discomfort in your tummy (abdomen), feel bloated or have indigestion or wind. Your doctor can give you drugs to help improve these symptoms. Tell them if the pain doesn’t improve or if it gets worse.

Effects on the kidneys

This treatment can affect how your kidneys work. This is usually mild and goes back to normal after treatment. You will have blood tests to check how well your kidneys are working.

It is important to drink at least 2 litres (3½ pints) of fluids each day to help protect your kidneys.

Contact your doctor or call the number you have been given, if you notice any blood in your urine.

Bladder irritation

Gemcitabine may irritate your bladder and cause discomfort when you pass urine. Drink plenty of fluids – at least 2 litres (3½ pints) during the 24 hours following chemotherapy. Contact the hospital straight away if you feel any discomfort or stinging when you pass urine, or if you notice any blood in it.

Effects on the liver

This treatment can affect how your liver works. This usually goes back to normal after treatment. You will have blood tests to check how well your liver is working during your treatment.

Fluid build-up (oedema)

Sometimes, fluid can build up in your legs and ankles which can cause swelling. This is known as oedema. Tell your doctor or nurse if fluid builds up. If your ankles and legs swell, it can help to put your legs up on a foot stool or cushion. The swelling usually gets better after your treatment ends.

Hair loss

Your hair will get thinner or you may lose all the hair from your head. You may also lose your eyelashes, eyebrows or other body hair. Hair loss usually starts after your first or second treatment.

Your nurse can talk to you about ways to cope with hair loss. There are ways to cover up hair loss if you want to. It is important to cover your head to protect your scalp when you are out in the sun.

Hair loss is almost always temporary and your hair will usually grow back after treatment ends.

Skin changes

Capecitabine may affect your skin. Your doctor or nurse can tell you what to expect. If your skin feels dry, try using an unperfumed moisturising cream every day. Capecitabine can cause a rash, which may be itchy. Always tell your doctor or nurse about any skin changes. They can give you advice and may give you creams or medicines to help. Any changes to your skin are usually temporary and improve when treatment finishes.

Very rarely, a much more serious skin condition can occur. You may have a skin rash which then blisters and your skin can peel. You may also feel unwell with flu-like symptoms such as a high temperature and joint pain. If you have these symptoms, you must stop taking the capecitabine and contact your doctors immediately.

Soreness and redness of palms of hands and soles of feet

This is called palmar-plantar or hand-foot syndrome. It gets better when treatment ends. Your doctor or nurse may prescribe creams to improve the symptoms. It can help to keep your hands and feet cool and to avoid tight-fitting socks, shoes and gloves.

Headaches

This treatment may cause headaches. If this happens, tell your doctor or nurse. They can give you painkillers.

Eye problems

This treatment may make your eyes feel sore, red and itchy (conjunctivitis). Your doctor will prescribe eye drops to help prevent this. It is important to use these as you are told to.

Less common side effects

Changes in the way the heart works

Capecitabine can affect the way your heart works. You may have tests to see how your heart is working before, during and sometimes after treatment. But, it is still possible for your heart to be affected even if these tests are normal. Very rarely, this can lead to heart failure or a heart attack. The risk of this happening is very low (less than 1 in 100 or 1%), but it is important that you know about it. Tell a doctor immediately if you have any of these symptoms at any time during treatment:

  • pain or tightness in your chest
  • breathlessness
  • changes to your heartbeat.

If you experience any of these symptoms, you should stop taking the Capecitabine tablets until you have spoken to your doctor. If you cannot get through to your doctor or the 24-hour number the hospital has given you then call the NHS urgent advice number which is 111.

Effects on the lungs

This treatment can cause changes to the lungs. Tell your doctor if you develop:

  • a cough
  • wheezing
  • a fever (high temperature)
  • breathlessness.

You should also tell them if any existing breathing problems get worse. You may have tests to check your lungs.

Muscle or joint pain

You may get pain in your muscles or joints for a few days after treatment. If this happens, tell your doctor so they can give you painkillers. Tell them if the pain does not get better. Having warm baths and taking regular rests may help.

Hearing changes

This treatment may cause hearing changes, including hearing loss. You may have ringing in the ears. This is called tinnitus. You may also become unable to hear some high-pitched sounds. Hearing changes usually get better after this treatment ends. But some can be permanent. Tell your doctor if you notice any changes in your hearing.

Effects on the nervous system

This treatment can affect the nervous system. You may feel anxious or restless, have problems sleeping or experience mood changes. You may feel drowsy, confused, dizzy or unsteady.

It is important not to drive or operate machinery if you notice these effects. Tell your doctor or nurse straight away if you notice any of these symptoms. Rarely, this treatment can cause seizures (fits).

Nail changes

Your nails may grow more slowly or break more easily. You may notice white lines across your nails, or other changes to their shape or colour. Once the treatment has ended, any changes usually take a few months to grow out.

There are things you can do to look after your nails:

  • Keep your nails and hands moisturised.
  • Wear gloves to protect your nails when you are doing things in the house or garden.
  • Do not use false nails during this treatment. It is fine to wear nail varnish.
  • If your toenails are affected, wear well-fitted shoes to cushion them.

Numb or tingling hands or feet (peripheral neuropathy)

This treatment affects the nerves, which can cause numb, tingling or painful hands or feet. You may find it hard to fasten buttons or do other fiddly tasks.

Tell your doctor if you have these symptoms. They sometimes need to lower the dose of the drug. The symptoms usually improve slowly after treatment finishes, but for some people they may never go away. Talk to your doctor if you are worried about this.

Hearing changes

This treatment may cause hearing changes, including hearing loss. Some people may have pain or ringing in their ears (tinnitus) and become unable to hear some high-pitched sounds. Tinnitus usually gets better after treatment ends. Some hearing changes can be permanent. Tell your doctor if you notice any changes in your hearing.

Other information

Blood clot risk

Cancer and some cancer treatments can increase the risk of a blood clot. Symptoms of a blood clot include:

  • pain, redness or swelling in a leg or arm
  • breathlessness
  • chest pain.

If you have any of these symptoms, contact a doctor straight away.

A blood clot is serious, but can be treated with drugs that thin the blood. Your doctor or nurse can give you more information.

Lactose

Capecitabine contains a small amount of lactose. If you have a lactose intolerance, talk to your doctor before you start taking this.

Other medicines

Some medicines can affect how this treatment works or be harmful when you are having it. Always tell your cancer doctor about any drugs you are taking or planning to take, such as:

  • medicines you have been prescribed
  • medicines you buy in a shop or chemist
  • vitamins, herbal drugs and complementary therapies.

Tell other doctors, pharmacists or dentists who prescribe or give you medicines that you are having this cancer treatment.

You can visit the electronic Medicines Compendium (eMC) for more detailed information about your treatment.

Alcohol

This treatment contains alcohol. If this is a problem for you, tell your doctor, nurse or pharmacist. Your blood alcohol level may be above the legal limit after you have the treatment. It is best not to drive or operate machinery for a few hours after having this treatment, even if you feel okay.

Contraception

Your doctor will advise you not to become pregnant or to make someone pregnant during treatment. This is because the drugs may harm a developing baby. It is important to use effective contraception during, and for 6 months after chemotherapy. You can talk to your doctor or nurse about this.

Sex

If you have sex during this course of chemotherapy, you need to use a condom. This is to protect your partner in case there is any chemotherapy in semen or vaginal fluids.

Breastfeeding

Women are advised not to breastfeed while having this treatment. This is because the drugs could be passed to the baby through breast milk.

Fertility

Some cancer drugs can affect whether you can get pregnant or make someone pregnant.

If you are a woman, your periods may become irregular or stop. This may be temporary, but for some women it is permanent. Your menopause may start sooner than it would have done.

There may be ways to preserve fertility for men and women. If you are worried about fertility, it is important to talk with your doctor before you start treatment.

Medical and dental treatment

If you need medical treatment for any reason other than cancer, always tell the doctors and nurses that you are having cancer treatment. Give them the contact details for your cancer doctor so they can ask for advice.

If you think you need dental treatment, talk to your cancer doctor or nurse. Always tell your dentist you are having cancer treatment.
