An absolute neutrophil count less than 200 is also considered a medical emergency and almost always requires hospital admission and initiation of broad spectrum antibiotics with selection of specific antibiotics based on local resistance patterns.Precautions to avoid opportunistic infections in those with chronic neutropenia include maintaining proper soap and water hand hygiene, good dental hygiene and avoiding highly contaminated sources that may contain a large fungal reservoirs such as mulch, construction sites and bird or other animal waste.Neutropenia can be treated with the hematopoietic growth factor granulocyte-colony stimulating factor (G-CSF). These are cytokines that are present naturally in the body. The factors promote neutrophil recovery following anticancer therapy or in chronic neutropenia. Recombinant G-CSF factor preparations, such as filgrastim can be effective in people with congenital forms of neutropenia including severe congenital neutropenia and cyclic neutropenia; the amount needed (dosage) to stabilize the neutrophil count varies considerably (depending on the individuals condition). Guidelines for neutropenia regarding diet are currently being studied. Those who have chronic neutropenia and fail to respond to G-CSF or who have an increased risk of developing MDS or AML (due to increased dosage requirements of G-CSF or having abnormal precursor cells in the bone marrow)  often require hematopoietic stem cell transplantation as a treatment.Most cases of neonatal neutropenia are temporary. Antibiotic prophylaxis is not recommended because of the possibility of encouraging the development of multidrug-resistant bacterial strains.These are cytokines that are present naturally in the body.
Therapy with 0.2–2 mg of flumazenil intravenously was found to decrease these symptoms in a placebo-controlled study. This is of interest as benzodiazepine receptor antagonists are neutral and have no clinical effects. The author of the study suggested the most likely explanation is past benzodiazepine use and subsequent tolerance had locked the conformation of the GABA-BZD receptor complex into an inverse agonist conformation, and the antagonist flumazenil resets benzodiazepine receptors to their original sensitivity. Flumazenil was found in this study to be a successful treatment for protracted benzodiazepine withdrawal syndrome, but further research is required. A study by Professor Borg in Sweden produced similar results in patients in protracted withdrawal. In 2007, Hoffmann–La Roche the makers of flumazenil, acknowledged the existence of protracted benzodiazepine withdrawal syndromes, but did not recommended flumazenil to treat the condition.Fluoroquinolone antibiotics have been noted to increase the incidence of a CNS toxicity from 1% in the general population, to 4% in benzodiazepine-dependent population or in those undergoing withdrawal from them. This is probably the result of their GABA antagonistic effects as they have been found to competitively displace benzodiazepines from benzodiazepine receptor sites. This antagonism can precipitate acute withdrawal symptoms, that can persist for weeks or months before subsiding. The symptoms include depression, anxiety, psychosis, paranoia, severe insomnia, paresthesia, tinnitus, hypersensitivity to light and sound, tremors, status epilepticus, suicidal thoughts and suicide attempt. Fluoroquinolone antibiotics should be contraindicated in patients who are dependent on or in benzodiazepine withdrawal.
