These side effects have been observed less commonly of patients receiving atezolizumab but may NOT be related to atezolizumab:
*A rare but possible side effect of this class of drug is the trigger of an auto-immune reaction. This can happen at any time when taking this drug, and/or after stopping the drug. The immune system may go after normal cells in the body, e.g. lungs, skin, intestines, endocrine system, liver, pancreas, eyes, etc. Symptoms and signs of this reaction will be closely monitored throughout treatment (e.g. cough, shortness of breath, wheezing, rash, diarrhea/blood in stool, fatigue/weakness, visual changes, etc.). Lab work will also be used to check for elevated liver enzymes, kidney thyroid function, electrolytes, glucose, and blood counts.
Contact your health care provider right away if you have any new or worsening symptoms.
Not all potential side effects are listed above. Some of those that are more rare are not listed here. However, you should always inform your health care provider if you experience any unusual symptoms or changes.

Always inform your health care provider if you experience any unusual symptoms or changes.
- Before starting atezolizumab treatment, make sure you tell your doctor about any allergies, and other medications you are taking (including prescription, over-the-counter, vitamins, herbal remedies, etc.) and your complete past medical, surgical, family and social history
- Do not receive any kind of immunization or vaccination without your doctor's approval while taking atezolizumab, e.g. it is OK to get inactivated/killed vaccines (flu vaccine), but not live vaccine (do not get flu-mist).
- Inform your health care professional if you are pregnant or may be pregnant prior to starting this treatment. Atezolizumab may be hazardous to the fetus. Adverse events were observed in animal reproduction studies. Women who are pregnant or become pregnant must be advised of the potential hazard to the fetus.
- For both men and women: Do not conceive a child (get pregnant) while taking atezolizumab. Barrier methods of contraception, such as condoms, are recommended during treatment. Women of child-bearing age should use effective contraception during therapy and for at least 5 months following treatment. Discuss with your doctor when you may safely become pregnant or conceive a child after therapy.
- Do not breast feed while taking this medication. Due to the potential for serious adverse reactions in the nursing infant, breast-feeding is not recommended during therapy or for at least 5 months after the last dose.
- If you have high blood sugar (diabetes), talk with your doctor. This drug might rarely raise blood sugar.
- Inform your doctor before starting treatment, especially if you have any history of autoimmune disease (e.g. psoriasis, rheumatoid arthritis, lupus erythematosus, multiple sclerosis, or any other), inflammatory bowel disease (e.g. ulcerative colitis, Crohn's disease, etc.), interstitial pneumonitis (e.g. chronic lung inflammation), hepatitis B or C, HIV, if you are getting steroids or other medications that suppress your immune system, and your recent vaccinations.
- If you go to any other health care provider or the Emergency Room, please let the provider know that you are taking this (or took it in the past) so they should take it into account for your management/plan of care.
Self-Care Tips (both general and related to atezolizumab):
- Drink at least two to three quarts of fluid every 24 hours, unless you are instructed otherwise.

- If you experience symptoms or side effects, be sure to discuss them with your health care team. They can prescribe medications and/or offer other suggestions that are effective in managing such problems.
Monitoring and Testing While Taking Atezolizumab:
You will be checked regularly by your health care professional while you are taking atezolizumab, to monitor side effects and check your response to therapy.
How Atezolizumab Works:
Atezolizumab is classified as a monoclonal antibody. Monoclonal antibodies are a relatively new type of "targeted" cancer therapy (against a specific "target").
Antibodies are an integral part of the body's immune system. Normally, the body creates antibodies in response to an antigen (such as a protein in a germ) that has entered the body.
The immune system utilizes activators/stimulators (accelerators) and checkpoints (breaks) to maintain the balance. One of those checkpoints is the interaction between two proteins, called PD-L1 and PD-1, that can cause suppression of the immune system and thus diminished attack against cancer cells. Both cancer cells and immune system cells can may over-express on their surface PD-L1, and this can reduce the attack of the immune system against cancer cells. Atezolizumab is a monoclonal antibody that attaches to PD-L1 and “blocks” its checkpoint function, thus ‘unleashing’ the brake on the immune system, to attack cancer cells
