Drug information provided by: Merative, Micromedex®
It is very important that your doctor check your progress at regular visits to make sure this medicine is working properly. Blood tests will be needed to check for unwanted effects.
Do not use this medicine together with clarithromycin (Biaxin®) and rifampin (Rifadin®).
Check with your doctor right away if you have any unusual bleeding or bruising, black, tarry stools, blood in the urine or stools, headache, dizziness, or weakness, pain, swelling, or discomfort in a joint, pinpoint red spots on your skin, unusual nosebleeds, or unusual vaginal bleeding that is heavier than normal. These may be signs of bleeding problems.
Pacritinib may cause diarrhea, nausea, or vomiting, and in some cases it can be severe. Do not take any medicine to treat diarrhea without first checking with your doctor. Diarrhea medicines may make the diarrhea worse or make it last longer. If you have any questions about this or if mild diarrhea, nausea, or vomiting continues, or gets worse, check with your doctor.
Pacritinib will lower the number of some types of blood cells in your body. Because of this, you may bleed or get infections more easily. To help with these problems, avoid being near people who are sick or have infections. Wash your hands often. Stay away from rough sports or other situations where you could be bruised, cut, or injured. Brush and floss your teeth gently. Be careful when using sharp objects, including razors and fingernail clippers.
Contact your doctor right away if you have any changes to your heart rhythm. You might feel dizzy or faint, or you might have a fast, pounding, or uneven heartbeat. Make sure your doctor knows if you had a heart rhythm problem, such as QT prolongation.
This medicine may increase your risk of serious heart or blood vessel problems, including heart attack or stroke. Call your doctor right away if you have chest pain or discomfort, confusion, difficulty in speaking, double vision, headache, inability to move arms, legs, or facial muscles, nausea, pain or discomfort in the arms, jaw, back, or neck, sweating, trouble breathing, or vomiting.
Check with your doctor right away if you have anxiety, chest pain, cough, dizziness, lightheadedness, or fainting, fast heartbeat, pain, redness, or swelling in the arm or leg, pains in the chest, groin, or legs, especially calves of the legs, severe headaches, sudden loss of coordination, sudden onset of slurred speech, sudden vision changes, or trouble breathing. These may be symptoms of serious blood clots (eg, deep vein thrombosis, pulmonary embolism, arterial thrombosis).
This medicine may increase your risk of cancer (eg, lymphoma, non-melanoma skin cancer). Tell your doctor right away if you have black, tarry stools, general feeling of illness, swollen glands, weight loss, yellow skin and eyes, persistent non-healing sore, reddish patch or irritated area, shiny bump, pink growth, or white, yellow or waxy scar-like area on the skin.
Your body's ability to fight infections may be reduced while you are using baricitinib. It is very important that you call your doctor at the first sign of an infection. Check with your doctor right away if you have a fever, chills, cough, flu-like symptoms, or unusual tiredness or weakness.
Some men who use this medicine have become infertile (unable to have children). Talk with your doctor before using this medicine if you plan to have children.
Make sure any doctor or dentist who treats you knows that you are using this medicine. You may need to stop using this medicine 7 days before having surgery or medical tests.
