Zidovudine
About Zidovudine
Zidovudine is an antiviral prescription medicine used to treat Human Immunodeficiency Virus (HIV-1) infection, helping to manage the virus in your body. It is also prescribed to pregnant individuals who are HIV-positive to help prevent passing the virus to their unborn babies. This medicine is available in oral forms, specifically capsules and tablets.
For Zidovudine to work effectively, it must be taken consistently and exactly at the scheduled times every day. You can take this medication with or without food, though taking it with a light meal may help if you experience stomach upset. Supporting your immune health with a nutrient-rich diet, regular physical activity, and adequate hydration can further improve your therapy results.
While taking Zidovudine, some people may experience common side effects like headaches, mild nausea, or a general feeling of tiredness. However, it is vital to consult your doctor immediately if you face serious side effects such as severe abdominal pain, sudden pale skin, or yellowing of your skin or eyes. These can indicate more serious underlying issues that require prompt clinical attention.
Before starting this medicine, tell your healthcare provider if you have a history of liver disease, kidney problems, or blood disorders like anemia. Do not take this if you have had a severe allergic reaction to Zidovudine or any of the inactive ingredients in the tablet or capsule in the past.
This medicine can interact with other treatments, such as certain antibiotics or other antivirals, because they can increase the risk of severe side effects on your kidneys or blood cells. It is also important for specific groups, including pregnant women, breastfeeding mothers, or elderly individuals, to consult their doctor before starting therapy to ensure it is safe for their unique needs.

Patients Concern
Disease/Condition Glossary
HIV Infection: Human Immunodeficiency Virus (HIV) is a retroviral infection that attacks and damages the cells of the immune system. This weakens the ability to fight against infections and diseases. If this condition is left untreated, it can lead to Acquired Immuno Deficiency Virus (AIDS). Symptoms of HIV include headache, fever, chills, joint pain, fatigue, swollen lymph nodes, sore throat, mouth nodes, muscle aches, etc. Zidovudine helps reduce the symptoms, control the infection, and also helps improve the HIV patient’s quality of life.
