Lamivudine and Zidovudine Tablets are a combination antiviral medicine used to manage HIV infection. Both drugs work together to reduce viral load and help the immune system function more effectively.

Here are the key details:

• Composition:

  • Lamivudine – a nucleoside reverse transcriptase inhibitor (NRTI) that blocks the virus from multiplying.

  • Zidovudine – another NRTI that interferes with HIV replication by targeting the reverse transcriptase enzyme.

• Main Use: Prescribed for managing HIV infection and sometimes for preventing mother-to-child transmission of HIV during pregnancy. The combination helps lower the amount of virus in the body and strengthens immune function.

• How It Works: Both drugs inhibit the reverse transcriptase enzyme, which HIV needs to replicate. By preventing viral multiplication, the drugs help the immune system recover and reduce the risk of AIDS-related complications.

• Administration: Taken orally, usually twice daily, as directed by the doctor. Doses should be taken at the same times each day, and it is important not to skip doses.

• Common Side Effects: Nausea, vomiting, diarrhea, headache, fatigue, dizziness, mild skin rash, or insomnia.

• Serious Concerns: Rarely, it may cause liver problems, bone marrow suppression (leading to low blood counts), lactic acidosis (buildup of lactic acid), or severe anemia.

• Precautions:

  • Regular monitoring of liver function, kidney function, and blood counts is recommended.

  • Do not stop taking the medication suddenly, as this may cause viral resistance.

  • Inform the doctor about all other medications or supplements being taken to prevent interactions.

• Storage: Store at room temperature, away from moisture, heat, and direct sunlight.
