What drugs cause leukocytosis?
Medications commonly associated with leukocytosis include corticosteroids, lithium and beta agonists. Increased eosinophil or basophil counts, resulting from a variety of infections, allergic reactions and other causes, can lead to leukocytosis in some patients.
What stimulates leukocytosis?
The mechanism that causes leukocytosis can be of several forms: an increased release of leukocytes from bone marrow storage pools, decreased margination of leukocytes onto vessel walls, decreased extravasation of leukocytes from the vessels into tissues, or an increase in number of precursor cells in the marrow.
What can cause leukocytosis?

Causes of leukocytosis
- infections.
- smoking.
- certain types of leukemia.
- emotional or physical stress.
- having your spleen removed.
- a reaction to medications, including steroids, lithium, or certain types of inhalers.

What medications can cause lymphocytosis?
Implicated drugs include phenobarbital, carbamazepine, phenytoin, lamotrigine, minocycline, sulfonamides, allopurinol, modafonil, and dapsone. Other drug hypersensitivity reactions (e.g., ethitoin, PAS, sulfasalazine, ginseng) may have an associated lymphocytosis.
What are the causes of leukocytosis and leukopenia?
Causes. (1) Infection—infectious mononucleosis, hepatitis, cytomegalovirus, rubella, pertussis, tuberculosis, brucellosis, syphilis; (2) endocrine disorders—thyrotoxicosis, adrenal insufficiency; (3) neoplasms—chronic lymphocytic leukemia (CLL), most common cause of lymphocyte count >10,000/μL.
What causes high WBC and high lymphocytes?

High lymphocyte blood levels indicate your body is dealing with an infection or other inflammatory condition. Most often, a temporarily high lymphocyte count is a normal effect of your body’s immune system working. Sometimes, lymphocyte levels are elevated because of a serious condition, like leukemia.
How can you increase your white cell count?
Eating Vitamin C will help regulate the levels of white blood cells in your body. Fruits like lemons, oranges, and lime are rich in vitamin C, and so are papayas, berries, guavas, and pineapples. You can also get vitamin C from vegetables such as cauliflower, broccoli, carrots, and bell peppers. Antioxidants.
Can antipsychotics cause leukocytosis?
Clozapine is an atypical antipsychotic drug that is approved by the US Food and Drug Administration (FDA) for the treatment of psychotic disorders. Agranulocytosis is a well-established side effect of clozapine; clozapine has also been associated with other blood dyscrasias like leukocytosis, albeit rarely.
How do you increase neutrophils?
Eating foods rich in vitamins B9 or B12 or taking these as supplements may help improve low neutrophil blood levels….How to raise neutrophil levels
- colony-stimulating factors.
