Possible health risks of pralatrexate injection

Pralatrexate injection, as a chemotherapy drug, has a powerful anti-cancer effect, but it may also bring certain health risks, especially when used for a long time or at high doses. Common health risks include but are not limited to the following:

Myelosuppression: One of the most common side effects of pralatrexate injection is myelosuppression, which is manifested by a decrease in white blood cells, red blood cells, and platelets. Myelosuppression may lead to an increased risk of anemia, bleeding, and infection. Therefore, patients require regular hematological monitoring during treatment.

Hepatic impairment: Pralatrexate injection may cause liver impairment, manifested as increased liver enzyme levels, and may even lead to jaundice or liver failure. Liver function needs to be monitored during treatment to ensure that the effects of the drug on the liver are within control.

Gastrointestinal reactions: Pralatrexate may cause gastrointestinal discomfort, including nausea, vomiting, oral ulcers, and loss of appetite. These symptoms are usually most noticeable during the first few weeks of treatment and require appropriate symptomatic management by a physician.

Hair loss: Like many other chemotherapy drugs, pralatrexate may cause hair loss. Although this side effect is temporary and hair usually grows back after treatment is completed, patients may experience some psychological distress during treatment.

Pulmonary toxicity: Pulmonary toxicity of pralatrexate may manifest as acute dyspnea, cough, chest pain and other symptoms. Although this side effect is uncommon, it may significantly affect a patient's respiratory function and requires early recognition and management.

Immunosuppression: Because pralatrexate suppresses bone marrow function, it may increase the risk of infections, especially bacterial and fungal infections. Therefore, patients need to remain alert to prevent infection and seek prompt medical treatment.
