Allergies: Always make sure your physician and nurses know if you have allergies. This includes allergies to such things as latex, tape and other adhesive material, and betadine/iodine, as well as to specific medications. If you are hospitalized make sure you have an allergy band on your wrist and that the nurses and physicians check it before giving you any type of treatment.  
Medications: Share all medications you are taking, even the ones that you take only occasionally. Medications include prescription drugs, over the counter medications such as aspirin, and herbs and supplements such as vitamins. Many medications interact with one another and it is important that your healthcare team knows everything that you are taking so that adverse reactions can be avoided. 
Young children/Pets/Living arrangements: Let your healthcare team know if you have small children at home. Young children are susceptible to childhood infections such as chicken pox that can be very dangerous to you during treatment if your immune system is lowered. Pets, especially cats, can carry the organism toxoplasmosis in their feces that can cause harmful infections in people with weakened immune systems. For this reason, do not empty litter boxes during treatment. Have another family member or a neighbor take care of this household chore for you to reduce your chances of exposure. Dust from construction can also kick up harmful germs and should be avoided if at all possible. 
Changes in body function: Report any changes in body function such as headaches, changes in bowel habits, bleeding, and shortness of breath with your healthcare provider. 
Lifestyle habits: Let your healthcare team know if you smoke, drink alcohol or use recreational drugs. This information is needed to ward off any complications that may occur as a result of these habits interacting with your disease and treatments.
