This medicine must be administered regularly for it to be effective. Continue Atezolizumab therapy even when you feel better. Do not stop your treatment unless instructed by the doctor.
What should I do if I have forgotten to use this medicine?
Ensure that you keep all appointments with your doctor so that you do not miss any doses. Your doctor also needs to regularly monitor your response to Atezolizumab.

If you miss an appointment or miss an injection, alert your doctor or nurse. A replacement appointment or injection should be given as soon as possible and the schedule of administration may be adjusted to maintain a 3-week interval between doses.
What should I take note of while using this medicine?
Inform your doctor if you have the following conditions:
  • history or current autoimmune disease (a condition where the immune system mistakenly attacks the body)
  • history or current infection
It is important that you do not get pregnant while being treated with Atezolizumab. You may wish to discuss birth control methods with your doctor or pharmacist.

Avoid breastfeeding during treatment and for 4 months after your final dose of this medicine.

Keep your appointments with your doctor. Your doctor needs to monitor your condition and check your response to the medication regularly.
  • Screening and assessment of tumour status may be needed to check the appropriateness of Atezolizumab therapy.
  • You may need to have regular blood tests to check your body’s response to the medicine and the health of your liver and thyroid gland. Your doctor will advise you how often you need to have them.
  • Regular monitoring of signs and symptoms of toxicity may also be needed while you are being treated with this medicine.
What side effects could I experience?
This medicine may cause tiredness. If affected, do not drive or take part in any activity in which you need to be alert.

Other side effects include any of the following: nausea, vomiting, diarrhoea, abdominal pain, fever, flu-like illness, cough, nasal congestion, chills, back pain, difficulty in breathing, decreased appetite, muscle cramps and spasms, tingling sensation and numbness; swallowing difficulties, shortness of breath, dizziness and fainting.

Some side effects may need immediate medical help. Alert your doctor quickly if you experience:
  • signs and symptoms of skin problems e.g. rashes with peeling of the skin or blistering of the lips, mouth or eyes (with or without fever)

If you develop rashes, breathlessness, swollen mouth or eyes, stop taking Atezolizumab and inform your doctor quickly. These could be signs of an allergic reaction.

This medicine will cause the level of your red blood cells, white blood cells and platelets to drop.

Red blood cells carry oxygen around your body. A fall in the level of red blood cells may make you feel tired and worn out.

White blood cells help your body to fight infections. A fall in the level of your white blood cells may put you at higher risk for infections, such as coughs, colds and flu, which may lead to more serious infections. Avoid crowded places and people who are sick. Alert your doctor if you have a fever, or a cough or flu that does not go away.

Platelets help your blood to clot when there is a cut in the skin. A fall in the level of your platelets may put you at risk of bleeding more than usual. Do not take part in activities where you may fall or get injured, such as contact sports. Alert your doctor if you get any unusual bruising (large bruises or several bruises, especially if the bruises appeared on their own) or bleeding that takes a long time to stop (for example, too much bleeding when you floss or brush your teeth).

Inform your doctor if any of these side effects do not go away or are severe, or if you experience other side effects.
Can I use this with other medicines?
Inform your doctor and pharmacist if you are taking medicines to treat systemic lupus erythematosus or SLE (an autoimmune disease that causes inflammation) e.g. belimumab.

Always notify your doctor and pharmacist if you are taking any other medicines, including herbal tonics such as traditional Chinese medicines, supplements and medicines that you buy without a prescription.
What special dietary instructions should I follow?
Avoid alcohol.
How should I store this medicine?
Store in the refrigerator, between 2-8°C. Do not allow to freeze. If frozen, this medicine will become ineffective and should not be used. Protect from light. Do not shake.

As this is a cancer medicine, any unused or expired medicine must be returned to the clinic, hospital or pharmacy for disposal.
