What you should tell your doctor or pharmacist during your treatment with GAVRETO:
Tell your healthcare provider immediately if you get any of these symptoms during treatment with GAVRETO:
- lung inflammation (pneumonitis). GAVRETO may cause severe, life-threatening or fatal swelling (inflammation) of the lungs during treatment. The signs may be similar to those from your lung cancer. Tell your doctor straight away if you have any new or worsening signs including difficulty in breathing, shortness of breath, cough with or without mucous, or fever.
- high blood pressure (hypertension). High blood pressure is common with GAVRETO and may sometimes be severe. Your doctor will monitor your blood pressure before you start treatment, then after 1 week of your treatment and then as needed. If you have high blood pressure, which is not well controlled with blood pressure medicines, please consult your doctor as it is important to make sure that your blood pressure is under control before starting GAVRETO treatment.
- liver problems (increased liver function blood test results). Liver problems (increased liver function blood test results) can happen during treatment with GAVRETO and may sometimes be serious. Your doctor will take blood tests before you start treatment, every 2 weeks for the first 3 months of your treatment and then as needed. This is to check that you do not have any liver problems while taking GAVRETO. Tell your doctor straight away if you get any of the following signs: yellowing of your skin or the whites of your eyes, pain on the right side of your stomach area, dark urine, itchy skin, feeling less hungry than usual, nausea or vomiting, feeling tired, bleeding or bruising more easily than normal.
- bleeding problems. Serious bleeding can occur during treatment with GAVRETO. Tell your doctor straight away if you are vomiting blood or vomit that looks like coffee - grounds, pink or brown urine, red or black (looks like tar) stools, coughing up blood or blood clots, unusual bleeding or bruising of your skin, menstrual bleeding that is heavier than normal, unusual vaginal bleeding, nose bleeds that happen often, drowsiness or difficulty being awakened.

Talk to your healthcare provider about the birth control methods that may be right for you and your partner.
For men
If your female partner is able to have children, you need to prevent pregnancy.
