Linezolid can lower the number of white blood cells in your blood temporarily, increasing the chance of getting an infection. It can also lower the number of platelets, which are necessary for proper blood clotting. If this occurs, there are certain precautions your doctor may ask you to take, especially when your blood count is low, to reduce the risk of infection or bleeding:

  • If you can, avoid people with infections. Check with your doctor immediately if you think you or your child are getting an infection or if you get a fever or chills, cough or hoarseness, lower back or side pain, or painful or difficult urination.
  • Check with your doctor immediately if you notice any unusual bleeding or bruising; black, tarry stools; blood in the urine or stools; or pinpoint red spots on your skin.

You may have trouble seeing or have a headache that won't go away. Ask your doctor what you should do if this happens. Some things that can lead to low blood sugar are exercising more than normal or waiting too long to eat.

To avoid this, do not eat large amounts of foods or drink beverages that have a high tyramine content (e.g., aged cheeses, air-dried, fermented, or smoked fish, meat, or poultry, sauerkraut, soy sauce, red wine, or tap beer. If a list of these foods and beverages is not given to you, ask your doctor to provide one.
