Carboplatin is a chemotherapy drug used to treat small-cell lung cancer and ovarian cancer. It can also be used to treat other types of cancer.
HOW IS CARBOPLATIN ADMINISTERED?
Carboplatin 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 carboplatin as a drip (perfusion) through a cannula or a line for about an hour. This kind of drip is usually given using a perfusion pump for the sake of timing.
Some people may have side effects while they are receiving chemotherapy.
On rare occasions, carboplatin can cause an allergic reaction while it is being administered. The signs of a reaction may include the following: rash, itchiness, breathlessness; swelling in the face or lips; nausea; pain in the abdomen, back, or chest; or feeling unwell. Tell your nurse immediately if you have any of these symptoms.
PAIN ALONG THE VEIN
If you feel pain in your vein, let your nurse know immediately; they will check the puncture site and the rate of administration to relieve you of your pain.
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 carboplatin normally lasts 21 days. Your doctor or nurse will tell you how many cycles you are going to have.
POSSIBLE SIDE EFFECTS OF CARBOPLATIN
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
Carboplatin may lower your number of white blood cells. 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
Carboplatin 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.
Carboplatin 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.
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.
CHANGES IN THE KIDNEYS
Carboplatin can affect the functioning of your kidneys. You will have blood tests before and during the treatment to see if this is the case. Your nurse will ask you to drink lots of fluids. Tell them if there are any changes in the amount of urine you produce.
CHANGES IN THE LIVER
Carboplatin can affect the functioning of your liver. These changes are normally mild and return to normal after the treatment. You will have blood tests done to see how your liver is working.
Carboplatin 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.
LESS COMMON SIDE EFFECTS OF CARBOPLATIN
CHANGES IN HEARING
Carboplatin can affect your ability to hear, though this is not a common occurrence. You may get a ringing in your ears (tinnitus) and lose the ability to hear certain high-pitched sounds. Patients' tinnitus normally gets better after the treatment has concluded. Some changes in hearing can be permanent. Tell your doctor if you notice any changes.
LOSS OF APPETITE
You may lose your appetite during the treatment. Try to eat frequent small 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 advice on getting more calories and proteins into your diet. They can give you nutritional supplements or good-tasting meal-replacement drinks.
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.
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.
Usually, people lose all of their hair. Also, the eyelashes, eyebrows, and other parts of the body may lose their hair. This 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 chemotherapy. Until the time when you hair grows back, it is important to cover your head so as to protect the scalp while it is exposed to the sun's rays. Your nurse can give you advice on how to cope with losing your hair.
TINGLING IN THE HANDS OR FEET
These symptoms are caused by the effect of carboplatin on the nerves. It is called peripheral neuropathy. It may also be hard for you to press buttons and it can make other tasks more uncomfortable. You may also feel a certain degree of pain at your nerve endings.
Tell your doctor if you have these symptoms. It is sometimes necessary to lower the drug dose. The symptoms normally get better slowly once the treatment is over, though in some people they never go away. Talk to your doctor if you are worried about this.
