It’s normal to be concerned about side effects and how they can affect you.

Ask what to expect
Talk to your doctor about what to expect when taking LYNPARZA. It may help you to have a better idea of what you might experience as you start treatment with LYNPARZA.

Write notes about how you’re feeling
Sharing your symptoms, how long they lasted and what made them better or worse, with your doctor can help them decide on ways to manage any side effects you may be experiencing.

Keep an open dialogue with your doctor
Keep your doctor informed of how you feel, if you’re going on a trip, or any other important changes that are happening in your life. You should always talk to your doctor about side effects you experience and how to manage them.
Talk to your doctor immediately if you are experiencing any of these symptoms while taking LYNPARZA
Serious side effects
LYNPARZA MAY CAUSE SERIOUS SIDE EFFECTS, INCLUDING:
BONE MARROW PROBLEMS CALLED MYELODYSPLASTIC SYNDROME (MDS) OR ACUTE MYELOID LEUKEMIA (AML):
Some people who have ovarian cancer or breast cancer and who have received previous treatment with chemotherapy, radiotherapy, or certain other medicines for their cancer have developed MDS or AML during treatment with LYNPARZA. MDS or AML may lead to death. If you develop MDS or AML, your doctor will stop treatment with LYNPARZA.
Symptoms of low blood cell counts are common during treatment with LYNPARZA, but can be a sign of serious bone marrow problems, including MDS or AML. Symptoms may include:
- Weakness
- Weight loss
- Fever
- Frequent infections
- Blood in urine or stool
- Shortness of breath
- Feeling very tired
- Bruising or bleeding more easily

Your doctor will do blood tests to check your blood cell counts
- Before treatment with LYNPARZA

- Weekly, if you have low blood cell counts that last a long time. Your doctor may stop treatment with LYNPARZA until your blood cell counts improve
Lung problems (pneumonitis)
Tell your doctor if you have any new or worsening symptoms of lung problems, including shortness of breath, fever, cough, or wheezing. Your doctor may do a chest x-ray if you have any of these symptoms.
Your doctor may temporarily or completely stop treatment if you develop pneumonitis. Pneumonitis may lead to death.

Some suggestions for managing your side effects
Talk to your doctor about the following ways that may help you cope with some of the most common side effects of LYNPARZA. This advice does not replace your doctor’s guidance.

Fatigue
- Balance your daily routine with both rest and physical activity. Try light exercise every day, with plenty of short naps or breaks
- Join a support group to help alleviate some of the mental stress that can contribute to feeling tired or weak
Nausea and vomiting
- Stay hydrated by drinking plenty of water and other caffeine-free, clear liquids
- Choose foods that are easy on the stomach (such as dry toast and crackers)
Diarrhea
- Eat more foods that are high in sodium and potassium (including bananas, oranges, boiled or mashed potatoes, and peach or apricot nectar) because you lose these important nutrients when you have diarrhea
Constipation
- Drink plenty of fluids each day (especially warm or hot fluids), as they may help with bowel movements
- Try to eat more high-fiber foods such as raw fruits and vegetables, raisins, prunes, and dates
Changes in taste or smell
- Avoid foods that don’t appeal to you
- Marinate or add extra flavors to improve the taste of food
Abdominal (stomach-area) pain
- Practice deep breathing, yoga, or find other ways to relax
- Ask your doctor about pain medicines that may help
- Tell your doctor about any severe or persistent abdominal pain
Decreased appetite
- Eat foods that are high in calories and easy to eat (such as pudding, ice cream, sherbet, or cream-based soups)
- Eat 6 to 8 small meals or snacks each day instead of 3 big meals
