Interactions between your drugs
chloramphenicol ophthalmic PONATinib
Applies to: chloramphenicol ophthalmic, Iclusig (ponatinib)
Consumer information for this interaction is not currently available.
GENERALLY AVOID: Coadministration of topical chloramphenicol with other agents that can cause bone marrow depression, aplastic anemia, or agranulocytosis may increase the risk and/or severity of hematologic toxicity. Chloramphenicol may be absorbed systemically from the eye, ear, and vagina. Bone marrow hypoplasia, including aplastic anemia and death, has been reported following topical use of chloramphenicol. However, systemic absorption following topical, ophthalmic, otic, and vaginal administration is generally minimal, and data concerning the incidence of blood dyscrasias following the use of topical chloramphenicol are not available.
MANAGEMENT: Concurrent use of topical chloramphenicol formulations with other bone marrow depressing agents should generally be avoided. If concomitant use on a long-term or intermittent basis is considered necessary, patients should be monitored for the development of hematologic adverse effects. Monitoring via full blood counts before and periodically during therapy may also be advisable.
Drug and food interactions
PONATinib food
Applies to: Iclusig (ponatinib)
Do not consume grapefruit, grapefruit juice, or any supplements that contain grapefruit extract during treatment with PONATinib unless directed otherwise by your doctor. Grapefruit juice can increase the blood levels of PONATinib. You may be more likely to experience side effects such as nausea; vomiting; abdominal pain; constipation; skin rash; mouth sores; high blood pressure; blood clots; fluid retention; heart failure; liver damage; and impaired bone marrow function resulting in low numbers of different types of blood cells, which can increase the risk of anemia, bleeding problems and infections. You should contact your doctor immediately if you develop sudden dizziness, fainting, chest pain, palpitation, shortness of breath, weakness on one side of the body, speech impairment, leg pain or swelling, or any signs of infection, as these may be symptoms of potentially serious side effects associated with PONATinib. You should also seek prompt medical attention if you have signs and symptoms of liver damage such as fever, chills, joint pain or swelling, unusual bleeding or bruising, skin rash, itching, loss of appetite, fatigue, nausea, vomiting, dark colored urine, light colored stools, and yellowing of the skin or eyes. 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.
