What drugs cause neutropenia in dogs?

Azathioprine. Administration of azathioprine to dogs has been associated with bone marrow toxicity. Neutropenia and thrombocytopenia or pancytopenia has been observed 1 to several months after initiation of treatment with immunosuppressive doses (2 mg/kg once daily) of azathioprine.

What drugs cause drug-induced neutropenia?

There are many medications that can result in drug-induced neutropenia. The most common are carbimazole, clozapine, dapsone, dipyrone, methimazole, penicillin G, procainamide, propylthiouracil, rituximab, sulfasalazine, and ticlopidine.

Which antibiotics cause neutropenia?

The drugs most commonly associated with neutropenia are antibiotics (particularly beta-lactam and trimethoprim-sulfamethoxasole) as well as antithyroid drugs, antiplatelet agents, nonsteroidal anti-inflammatory agents, and noramidopyrin (3).

What drugs cause high neutrophils?

GCSFs, such as Neupogen (filgrastim, Amgen), Granix (tbo-filgrastim, Cephalon, Inc.), and Zarxio (filgrastim-sndz, Sandoz), stimulate and promote the maturation and activation of neutrophils. This class of drugs can also enhance the exodus of mature neutrophils trapped within the bone marrow.

What causes low neutrophil count in dogs?

Neutropenia is a decrease in the number of neutrophils in the bloodstream. It may occur due to the white blood cells sticking to the walls of damaged blood vessels, destruction of neutrophils, or reduced formation in the bone marrow. Neutropenia may occur in all species during overwhelming bacterial infections.

Can phenobarbital cause neutropenia?

Sensitivity to phenobarbital and related anticonvulsants may induce life-threatening leukopenia, thrombocytopenia, and anemia in dogs. Phenobarbital-induced neutropenia in these 3 dogs may have posed a risk for developing bacteremia.

Does bleomycin cause neutropenia?

Bleomycin, etoposide, and cisplatin (BEP) chemotherapy has been positioned as the standard of care of initial treatment for advanced germ cell tumors (GCT). The most serious side effects of BEP therapy are neutropenia and febrile neutropenia (FN).

What is the most common cause of neutropenia?

Common causes include HIV, hepatitis, tuberculosis, sepsis, and Lyme disease, among other infections. Cancer: Cancer and other blood and/or bone marrow disorders, including leukemia and lymphoma, can prevent your body from making enough healthy white blood cells, causing neutropenia.

How is drug induced neutropenia treated?

After drug removal, most cases of neutropenia resolve over time, and only symptomatic therapy such as antibiotics for treatment and prophylaxis of infections and good hygiene practices are necessary. The average time for full recovery of the neutrophil count is 9 days (range, 9-24 days).

Can Zithromax cause neutropenia?

Significant abnormalities (irrespective of drug relationship) occurring during the clinical trials were reported as follows: elevated ALT (SGPT), AST (SGOT), creatinine (4 to 6%) elevated LDH, bilirubin (1 to 3%) leukopenia, neutropenia, decreased platelet count, and elevated serum alkaline phosphatase (less than 1%)

Can steroids cause neutropenia?

Glucocorticoids, anabolic steroids, and vitamins do not stimulate neutrophil production but can affect distribution and destruction. If acute neutropenia is suspected to be drug- or toxin-induced, all potentially etiologic agents are stopped.

How is neutropenia treated in dogs?

Treatment. The first consideration for treatment is secondary infection. If there is no fever, antibiotics will be prescribed. If the dog has a fever, the treatment will be more aggressive.

How can I raise my dogs white blood cells?

Treatment of Low White Blood Cell Count in Dogs Dogs with bacterial infections will be given antibiotics. This will help to support the immune system which is weakened with any type of leukopenia, whether bacterial infection is the primary cause or not.

Can phenobarbital cause low white blood count?

Blood disorders caused by phenobarbital include decreased levels of red blood cells, white blood cells, and platelets, which can result in lethargy, decreased appetite, increased susceptibility to infections, and spontaneous bleeding.

How do you treat low white blood cells in dogs?

If there is no fever, antibiotics will be prescribed. If the dog has a fever, the treatment will be more aggressive. The dog will probably be hospitalized and antibiotics administered through an IV. If anemia is acute, a transfusion may also be necessary.

Does bleomycin cause neurotoxicity?

Osmotic blood-brain barrier modification was used to increase delivery of bleomycin and 5-fluorouracil to the ipsilateral brain region, but the increased delivery was associated with evident neurotoxicity.

What are the long term effects of bleomycin?

The chemo drug bleomycin can damage the lungs, as can radiation therapy to the chest. This can lead to problems like shortness of breath, which might not show up until years after treatment. Smoking can also seriously damage the lungs, so it’s important that people who have had these treatments do not smoke.

Can neutropenia be reversed?

Transient neutropenia, in most circumstances, is reversible with removal of the offending agent. Neutropenia is defined as an absolute neutrophil count (ANC) < 1,500/μL.

How long does it take for neutropenia to resolve?

Can amoxicillin cause neutropenia?

The drugs most frequently associated with IDIN include metamizole, clozapine, sulfasalazine, thiamazole, carbimazole, amoxicillin, cotrimoxazole, ticlopidine, and valganciclovir.

Which medications are associated with Idin-induced neutropenia?

Clozapine is perhaps the drug most often associated with IDIN. Clozapine-induced neutropenia occurs in ∼1% of patients, usually during the first 3 months of treatment.

Can phenobarbital cause neutropenia in dogs?

Sensitivity to phenobarbital and related anticonvulsants may induce life-threatening leukopenia, thrombocytopenia, and anemia in dogs. Phenobarbital-induced neutropenia in these 3 dogs may have posed a risk for developing bacteremia.

What is drug-induced neutropenia?

This article has been cited by other articles in PMC. Drug-induced neutropenia is a potentially serious and life-threatening adverse event that may occur secondary to therapy with a variety of agents. Cytotoxic chemotherapy can cause a predictable and dose-related decrease in neutrophil count.

What is the ANC of a patient with neutropenia?

His ANC was 360 cells/mcL (neutropenic). The patient had not demonstrated neutropenia from the time of his diagnosis until his ED presentation. On presentation, the patient had a maximum body temperature (T max) of 103.2° F, a blood pressure of 125/48 mm Hg, and a heart rate of 114 beats per minute.
