Olasym 100 Tablet is a prescription medicine used in the treatment of ovarian and breast cancer. It works by blocking an enzyme called PARP, which helps fix damaged DNA. By stopping PARP, the medicine prevents cancer cells from repairing themselves, leading them to die off and slowing tumor growth. Olasym 100 Tablet may be taken with or without food. Swallow the tablets whole, without crushing, chewing, or splitting them. Take it regularly and at the same time every day to maintain an even level of the medication in your body. Follow your doctor’s instructions on the exact dosage and schedule. Common side effects include nausea, fatigue, vomiting, loss of appetite, diarrhea, and dizziness. If you experience nausea or vomiting, eating smaller, more frequent meals and staying hydrated can help. Inform your doctor if these side effects become severe or do not go away. Be cautious about driving or operating heavy machinery if you feel dizzy or fatigued. While taking Olasym 100 Tablet, avoid consuming grapefruit or grapefruit juice as it can increase the risk of side effects. This medicine can cause harm to an unborn baby, so it is important to use effective contraception during treatment and for some time after the last dose. Inform your doctor if you are pregnant, planning to become pregnant, or breastfeeding. Regular blood tests are needed to monitor your blood cell counts and liver function during treatment. Do not start any new medications or supplements without consulting your doctor, as they may interact with Olasym 100 Tablet.
