Drug Interactions between olaparib and selegiline

While you are taking selegiline, you must not eat or drink certain foods and beverages that are high in tyramine. Eating these foods while you are taking selegiline can raise your blood pressure to dangerous levels. This may cause life threatening symptoms such as sudden and severe headache, confusion, blurred vision, problems with speech or balance, nausea, vomiting, chest pain, seizure (convulsions), and sudden numbness or weakness (especially on one side of the body). Call your doctor at once if you have any of these symptoms. Foods that are high in tyramine include: air dried meats, aged or fermented meats, sausage or salami, pickled herring, and any spoiled or improperly stored beef, poultry, fish, or liver, red wine, beer from a tap, beer that has not been pasteurize, aged cheeses, including blue, brick, brie, cheddar, parmesan, romano, and swiss, sauerkraut, over the counter supplements or cough and cold medicines that contain tyramine, soy beans, soy sauce, tofu, miso soup, bean curd, fava beans, or yeast extracts (such as Marmite).

Do not consume grapefruit, grapefruit juice, or Seville oranges during treatment with olaparib. Doing so can significantly increase the blood levels of olaparib and increase the risk and/or severity of side effects such as nausea, vomiting, diarrhea, indigestion, loss of appetite, abdominal pain or discomfort, lung problems, and impaired bone marrow function resulting in low numbers of different types of blood cells. You may also be more likely to develop anemia, bleeding problems, or infections due to low blood cell counts. Talk to your doctor if you have any questions or concerns. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Using selegiline together with ethanol (alcohol) may increase side effects such as dizziness, drowsiness, confusion, and difficulty concentrating. Some people may also experience impairment in thinking, judgment, and motor coordination. You should avoid or limit the use of alcohol while being treated with selegiline. Do not use more than the recommended dose of selegiline, and avoid driving, operating machinery, or engaging in potentially hazardous activities requiring mental alertness and motor coordination until you know how the medication affects you.
