Proper use of acalabrutinib

Precautions while using acalabrutinib
It is very important that your doctor check your progress at regular visits to make sure acalabrutinib is working properly. Blood tests may be needed to check for unwanted effects.
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.
Make sure any doctor or dentist who treats you knows that you are using acalabrutinib. You may need to stop using acalabrutinib several days before and after having surgery.
Call your doctor right away if you start to have a cough that would not go away, weight loss, night sweats, fever, chills, flu-like symptoms (such as a runny or stuffy nose, headache, blurred vision, or feeling generally ill), painful or difficult urination, or sores, ulcers, or white spots in the mouth or on the lips. These may be signs that you have an infection.
Acalabrutinib may 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.
Using acalabrutinib may increase your risk of getting new cancers, including skin cancer. Avoid sun exposure. Use a sunscreen when you are outdoors. Avoid sunlamps and tanning beds.
Acalabrutinib may cause heart rhythm problems (eg, atrial flutter, atrial fibrillation). Check with your doctor right away if you have a fast or irregular heartbeat, trouble breathing, lightheadedness, dizziness, or fainting.
Using acalabrutinib while you are pregnant can harm your unborn baby and problems during childbirth. Use an effective form of birth control to keep from getting pregnant during treatment and for at least 1 week after your last dose. If you think you have become pregnant while using the medicine, tell your doctor right away.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.
