Raltitrexed is a chemotherapy drug used to treat intestinal cancer.
HOW IS RALTITREXED ADMINISTERED?
Raltitrexed is given in the chemotherapy day unit or during a hospital stay. A chemotherapy nurse will give it to you.
Before the day of treatment, a nurse will take a blood sample from you to see if you are fit for chemotherapy.
You will also be able to see a doctor or nurse before having chemotherapy. They will ask you how you have been feeling. If the results of your blood test are good on the day of your treatment, the pharmacist will prepare your chemotherapy. Your nurse will give you medication for nausea and, sometimes, steroids administered intravenously. Chemotherapy drugs may be given in the following ways:
- Through a thin tube (line) inserted into a vein in the arm or hand by a nurse
- Through a tube that goes below the skin of your chest to a nearby vein (central line)
- Through a thin tube that is placed in a vein of the arm and goes up through a vein toward the chest (PICC)
Your nurse will give you raltitrexed as a drip (perfusion) through a cannula or a line for about 15 minutes. This kind of drip is usually given using a perfusion pump for the sake of timing.
YOUR CHEMOTHERAPY CYCLE
You will have chemotherapy as part of a course or cycle, consisting of several treatment sessions and lasting several months. Each cycle of raltitrexed normally lasts 21 days. Your doctor or nurse will tell you how many cycles you are going to have.
POSSIBLE SIDE EFFECTS OF RALTITREXED
You may experience some of the side effects mentioned here, though it is rare for a patient to have all of them. If you receive other chemotherapy drugs, you may have other side effects that are not mentioned here. Always inform your doctor of the effects you experience.
Your doctor can prescribe medication to help control some of the side effects. It is very important to take the medication exactly as your doctor says for it to have the highest chance of working well. Your nurse will advise you on managing the side effects. After treatment, the side effects start to get better.
RISK OF INFECTION
Raltitrexed may lower the number of white blood cells in your blood. This will make you more susceptible to infection. Your nurse can tell you when you might have the lowest levels of these cells. When the number of white blood cells is low, this is called neutropenia.
Contact your hospital immediately if any of the following happens:
- your temperature goes above 38 ° C
- you suddenly feel unwell, even if your temperature is normal.
- You have symptoms of infection, which may include sore throat, coughing, or the need to urinate frequently.
The number of white blood cells normally increases gradually, returning to normal before your next chemotherapy session. You will have a blood test before your next chemotherapy. If your white blood cells are still low, your doctor may postpone the treatment for a short period of time.
BRUISING AND BLEEDING
Raltitrexed may lower the number of platelets in your blood. Platelets are cells that help the blood to clot. Tell your doctor if you have any unexplained bleeding or bruising. This includes nosebleeds, bleeding gums, blood spots, or skin eruptions (rashes). Some people may require additional platelets.
Raltitrexed may lower the number of red blood cells in your blood. Red blood cells transport oxygen throughout the body. If you have a low number of red blood cells, you may be tired and short of breath. Tell your doctor or nurse if you feel like this. If you are very anemic, it's possible you will require a blood transfusion.
This can happen on the first few days after chemotherapy. Your doctor will prescribe you antiemetic drugs to help prevent or control your nausea. It is easier to prevent nausea than it is to treat it once it has begun.
If you still have nausea or are vomiting, get in touch with the hospital as soon as possible. They can give you advice and change your medication to one that works better.
Your doctor can prescribe medicines to control diarrhea. Let them know if your diarrhea is severe or if it doesn't get better. Make sure you drink at least two liters of fluids each day if you have diarrhea.
LOSS OF APPETITE
You may lose your appetite during the treatment. Try to eat in small quantities and have frequent meals. Don't worry if you don't eat much for a day or two. If your appetite doesn't get any better after a few days, tell your nurse or dietitian. They can give you nutritional supplements or good-tasting meal-replacement drinks.
ABDOMINAL PAIN AND CONSTIPATION
Raltitrexed can cause constipation and abdominal pain. Drinking at least two liters of fluids each day will help if this is the case. Try to eat more high-fiber foods such as fruit, vegetables, and whole-grain bread and get some light exercise.
SORENESS OF THE MOUTH
You may have a sore mouth or mouth ulcers, which could make you more prone to getting a mouth infection. Lightly brush your teeth and/or dentures in the morning and night and after meals. Use a soft-bristle toothbrush. Your nurse might ask you to rinse your mouth out regularly or use mouthwash. It is important that you follow all the instructions you are given and that you drink a lot of fluids.
Tell your nurse or doctor if you have any mouth problems. They can prescribe you drugs to prevent or treat infections of the mouth and to treat any kind of pain.
Feeling very tired is a common side effect. Fatigue is often worst toward the end of treatment and for a few months after the treatment has finished. Try to pace yourself and rest as much as you need to. Help balance this with a bit of light exercise, such as short walks. If you feel drowsy, don't drive or operate heavy machinery.
Chemotherapy can affect your skin. Raltitrexed can produce a rash, which may cause itchiness. If your skin is dry, try to use a fragrance-free moisturizing cream every day. Always tell your doctor about any change to your skin. These changes can be temporary, improving once the treatment is over.
CHANGES IN THE LIVER
Treatment with raltitrexed can cause changes in the way your liver works, although this will return to normal once your treatment is over. It is very unlikely you will notice any problems, though will have periodic blood tests to check whether your liver is working properly.
LESS COMMON SIDE EFFECTS OF RALTITREXED
Your hair may thin out, though it is unlikely you will lose all of the hair on your head. Hair loss normally starts after your first or second cycle of chemotherapy. It is almost always temporary, and the hair will continue to grow after you finish your treatment.
Your ankles and legs may swell because of the build up of fluid in this area. Doctors can prescribe steroids to help prevent this, so let your physician known if your legs or ankles become swollen. Try to put your feet up on a stool or a cushion. The inflammation gets better when the treatment ends.
ACHING OR PAIN IN THE JOINTS AND MUSCLES
You may have pain in your joints or muscles for a few days after chemotherapy. Tell your doctor if this happens so they can prescribe you some painkillers. Let them know if your pain doesn't go away. Try to get lots of rest. Taking warm baths on a regular basis can help.
CHANGES IN TASTE
You may get a strange taste in your mouth or find that food tastes different. This should go away once the treatment is over. Unless you have pain or mouth ulcers, try to use herbs and spices or strong-tasting sauces to give your food more flavor. Sucking on candy can help bitter or metallic tastes go away.
You may get headaches more frequently. Tell your doctor, as he or she may prescribe painkillers to help.
It is important for you to tell your doctor or nurse immediately if you feel ill or develop severe side effects. This includes any that are not mentioned here.
