Each person's reaction to chemotherapy is different. Some people have very few side effects, while others may experience more. The side effects described in this information will not affect everyone who is having ESHAP or R‑ESHAP chemotherapy. We have outlined the most common side effects, so that you can be aware of them if they occur. However, we have not included those that are rare and therefore unlikely to affect you. If you notice any effects that you think may be due to the drug, but which are not listed in this information, please let your nurse or doctor know.
Feeling sick (nausea) and being sick (vomiting) Your doctor can prescribe very effective anti-sickness (anti-emetic) medicines to prevent or reduce nausea and vomiting. If the sickness is not controlled, or if it continues, tell your doctor. They can prescribe other anti-sickness medicines which may be more effective. Some anti-sickness medicines can cause constipation. Let your doctor or nurse know if this is a problem.
Lowered resistance to infection ESHAP chemotherapy reduces the production of white blood cells by the bone marrow, making you more prone to infection. This effect can begin seven days after treatment has been given, with your resistance to infection usually reaching its lowest point 10–14 days after chemotherapy. Your blood cells will then increase steadily and will usually have returned to normal levels before your next cycle of chemotherapy is due. You may be given antibiotics to take as a preventative measure (known as prophylactic antibiotics).
Contact your doctor or the hospital straightaway if:
- your temperature goes above 38ºC (100.5ºF)
- you suddenly feel unwell (even with a normal temperature).
You will have a blood test before having more chemotherapy to make sure that your number of white blood cells has returned to normal. Occasionally, it may be necessary to delay treatment if your number of blood cells (blood count) is still low.
You may be given injections of a drug called G-CSF (granulocyte-colony stimulating factor), which is a protein that can help to boost the number of white blood cells that your bone marrow produces. It is given as an injection under the skin (subcutaneously).
Bruising or bleeding ESHAP can reduce the production of platelets (which help the blood to clot). Let your doctor know if you have any unexplained bruising or bleeding, such as nosebleeds, blood spots or rashes on the skin, and bleeding gums.
Anaemia (low number of red blood cells) While having this treatment you may become anaemic. This may make you feel tired and breathless. Let your doctor or nurse know if these effects are a problem.
Your kidney function may be affected Usually this does not cause any symptoms and any effect on your kidneys is generally mild. Rarely, it may cause permanent damage to the kidneys unless the treatment is stopped. Before each treatment you will have a blood test to check how well your kidneys are working. You will be asked to drink more than normal on the day after treatment. It is important to tell your doctor or chemotherapy nurse if you are not able to drink enough. Tell your doctor or nurse if you are passing less urine than normal.
Allergic reaction It is possible to have a slight allergic reaction to rituximab. Signs of this include skin rashes and itching, a feeling of swelling of the tongue or throat, irritation of the nasal passages, wheezing, a cough and breathlessness. You will be monitored closely during your treatment, but tell your doctor or nurse if you have any of these effects. Certain drugs (chlorpheniramine and paracetamol) can be given to reduce the chance of developing an allergic reaction. The rituximab infusion can also be slowed-down or stopped until the reaction is over.
Flu-like symptoms Some people find that rituximab can cause headaches, aching joints and muscles, a temperature, lethargy (feeling of having no energy) and chills. These side effects can occur while the drug is being given, but do not usually last long.
Low blood pressure This may happen during the infusion of rituximab, so your blood pressure will usually be regularly checked. People who normally take drugs to lower their blood pressure may be advised by their doctor to take these at least 12 hours before rituximab is given. It is important not to alter your blood pressure medication without first discussing it with your doctor.
Sore mouth and ulcers Your mouth may become sore, or you may notice small ulcers during this treatment. Drinking plenty of fluids, and cleaning your teeth regularly and gently with a soft toothbrush, can help to reduce the risk of this happening. You will be given mouthwashes to help keep your mouth clean and prevent infection. Your nurse will show you how to use these. Let your doctor know if you develop any problems, as you may need painkillers or antibiotics if your mouth becomes sore and infected.
Tiredness Many people feel very tired (fatigued) during chemotherapy, particularly towards the end of treatment. This is a very common side effect and it is important to try to get as much rest as you need.
Gritty and sore eyes (conjunctivitis) This can happen because cytarabine can cause inflammation of the conjunctiva (the membrane that covers the white part of the eye and lines the eyelids). You will be given steroid eye drops to help prevent this side effect occurring. It is important to follow the instructions you are given.
Hair loss This usually starts 3–4 weeks after the first dose of chemotherapy, although it may occur earlier. Hair may be lost completely. You may also have thinning and loss of eyelashes, eyebrows and other body hair. Hair loss is temporary and your hair will start to grow again once the treatment ends.
Irritation of stomach lining Methylprednisolone can lower the production of protective stomach mucus. This can irritate the lining of your stomach and may cause or aggravate an ulcer. To help reduce this effect, the methylprednisolone is usually given in injection form (intravenously). Tell your doctor if you have any indigestion, stomach pains or abdominal discomfort.
The levels of sugar in your blood may change While you are having steroids as part of the ESHAP regimen, your blood sugar levels may be checked with blood tests. You may be asked to test your urine for sugar. You will be shown how to do this.
People with diabetes should be more careful than usual when checking their blood sugar levels. You should contact your doctor if you have any problem controlling your diabetes. Also, tell your doctor if you get thirsty or if you are passing more urine than usual.
