ERIBULIN MESYLATE Page 5 INTRAVENOUS CANCER TREATMENT EDUCATION Handling body fluids and waste Some of the drugs you receive may be present in urine, stool, sweat, or vomit for many days after treatment. Many cancer drugs are toxic, your bodily waste may also be toxic and can be dangerous to come into contact with. Once you have started eribulin mesylate, follow the instructions below for at least two days after your treatment. This is to keep you, your loved ones, and the environment as safe as possible. o Pregnant women should avoid touching anything that may be soiled with body fluids from the patient. o Toilet and septic systems • You may use the same toilet, septic tank, and/or sewer that you usually use. If you have a low-flow toilet, close the lid and flush twice to ensure that all waste has been discarded. o If the toilet or toilet seat becomes soiled with urine, stool, or vomit, clean the surface after every use before other people use the toliet. o Wash hands with soap and water after using the toilet for at least 20 seconds. o If you need a bedpan, be sure your caregiver knows to wear gloves to assist with cleanup and to wash the bedpan with soap and water every day. o If you do not have good control of bladder or bowels, use a disposable pad with a plastic back, a diaper, or a sheet to absorb body waste. o Wash any skin that has been exposed to body waste with soap and water. o Linens or clothing that are soiled with body fluids or body waste should be washed separately from other linens and clothing. If you do not have a washer, place the soiled linens in a plastic bag until they can be washed. o Wash hands with soap and water after touching linens or clothing that may be soiled with body fluids. Intimacy, sexual activity, contraception, and fertility This treatment may cause changes that can affect intimacy and sexuality, including desire and body image. Maintaining physical closeness and/or intimacy with loved ones can be continued during treatment. Holding hands, hugging, and kissing can be done safely. It is recommended that you talk to your care team about any restrictions or questions you may have. Some treatments can influence the ability to have children, also known as fertility. If you’re interested in preserving fertility, talk to your care team before treatment. Ask your healthcare provider to determine when it is safe to become pregnant after your treatment. Patients of reproductive ability should not become pregnant or get their partners pregnant while receiving eribulin mesylate. Some of the drugs you receive may be present in semen and vaginal secretion for many days after treatment. You should use barrier devices, such as condoms, during sexual activity to limit exposure to body fluids. o Talk to your care team about birth control. Not all options may be right for your treatment or cancer. Effective contraception could include one or more of the following: barrier methods (e.g., condoms), hormone methods (e.g., birth control pills), or surgery. o Tell your care team if you become pregnant or plan to breastfeed.
