WARNING

Zidovudine, commonly known as AZT (zidovudine), is an antiretroviral medication used to treat HIV/AIDS. Zidovudine Injection is a form of the drug administered intravenously. While it can be effective in managing HIV infection, like any medication, it comes with potential risks and side effects. Here are some of the risks associated with taking Zidovudine Injection:

• Bone Marrow Suppression: Zidovudine can suppress the bone marrow’s ability to produce blood cells, leading to anemia (reduced red blood cell count), neutropenia (reduced white blood cell count), and thrombocytopenia (reduced platelet count).
• Gastrointestinal Issues: Common side effects include nausea, vomiting, and diarrhea. These symptoms can be bothersome and may affect the patient’s quality of life.
• Lactic Acidosis: In rare cases, Zidovudine use has been associated with lactic acidosis, a serious condition characterized by an excess buildup of lactic acid in the body. This can lead to symptoms such as weakness, rapid breathing, abdominal pain, and more.
• Muscle Weakness: Zidovudine may cause muscle weakness or muscle pain, although this is less common.
• Liver Problems: Some individuals may experience elevated liver enzymes or other liver-related issues while taking Zidovudine.
• Fat Redistribution: Long-term use of certain antiretroviral medications, including Zidovudine, has been associated with fat redistribution in the body, leading to changes in body shape and fat accumulation.
• Mitochondrial Toxicity: Zidovudine can affect the mitochondria, which are the energy-producing structures within cells. This may contribute to some of the side effects mentioned above.

It’s important for individuals taking Zidovudine Injection to be closely monitored by healthcare professionals, especially considering potential hematologic and metabolic complications. The decision to use this medication should be made in consultation with a healthcare provider who can assess the individual’s overall health and consider potential risks and benefits. Regular medical check-ups and blood tests are often conducted to monitor for any adverse effects.

Why is this medication prescribed?

Zidovudine, often referred to as AZT, is a medication used in the treatment of HIV/AIDS. It belongs to a class of drugs called nucleoside reverse transcriptase inhibitors (NRTIs), which work by inhibiting the replication of the HIV virus. Zidovudine is prescribed to slow down the progression of HIV infection and reduce the risk of complications associated with AIDS. Zidovudine is used as part of combination therapy to treat HIV infection in adults and pediatric patients.
