Drug Interactions between amlodipine / celecoxib and idelalisib

Idelalisib may increase the blood levels of amLODIPine. You may be more likely to experience serious side effects such as irregular heart rhythm, fluid retention, swelling, heart failure, and excessively low blood pressure. You may need a dose adjustment or more frequent monitoring by your doctor to safely use both medications. You should seek medical attention if you develop dizziness or fainting; sudden, unexplained weight gain; swelling of the hands, ankles, or feet; chest pain; or difficulty breathing during treatment with these medications. Avoid driving or operating hazardous machinery until you know how the medications affect you, and use caution when getting up from a sitting or lying position. 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.

Idelalisib may cause serious and life-threatening liver problems, and using it with other medications that can also affect the liver such as celecoxib may increase that risk. You should avoid or limit the use of alcohol while being treated with these medications. Talk to your doctor if you have any questions or concerns. Your doctor may already be aware of the risks, but has determined that this is the best course of treatment for you and has taken appropriate precautions and is monitoring you closely for any potential complications. Call your doctor immediately if you have fever, chills, joint pain or swelling, unusual bleeding or bruising, skin rash, itching, loss of appetite, fatigue, nausea, vomiting, abdominal pain, dark urine, pale stools, and/or yellowing of the skin or eyes, as these may be signs and symptoms of liver damage. You may need a dose adjustment or an interruption in idelalisib therapy if you develop severe liver problems. 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.
