Zidovir 100mg

Zidovir 100mg

Zidovir 100mg contains Zidovudine, an antiretroviral medication used to treat HIV/AIDS. It belongs to the nucleoside reverse transcriptase inhibitor (NRTI) class, which helps reduce the virus’s ability to multiply in the body. Zidovir is often prescribed as part of combination therapy to improve immune function and lower viral load.

The usual dosage depends on the patient’s condition and medical history. Side effects may include nausea, fatigue, headache, and anemia. Regular blood tests are necessary to monitor health while on Zidovir. It is not a cure for HIV but helps manage the infection effectively.

Uses 

• HIV Treatment – Zidovir (Zidovudine) is used in combination with other antiretroviral drugs to manage HIV infection by reducing viral replication.
• Prevention of Mother-to-Child Transmission (PMTCT) – It is prescribed during pregnancy and childbirth to lower the risk of transmitting HIV to the baby.
• Post-Exposure Prophylaxis (PEP) – Zidovir is sometimes included in PEP regimens to prevent HIV infection after exposure.

How to Use Zidovir 100 mg?

• Dosage – Take Zidovir exactly as prescribed by your doctor. The usual dose depends on your medical condition and weight.
• Timing – Take it at evenly spaced intervals to maintain a constant level in your blood.
• With or Without Food – You can take Zidovir with or without food, but taking it with food may help reduce stomach discomfort.
• Swallow Whole – Do not crush, chew, or break the tablet; swallow it with water.
• Missed Dose – If you miss a dose, take it as soon as you remember. If it’s close to your next dose, skip the missed one.
• Do Not Stop Suddenly – Stopping Zidovir without medical advice can worsen your condition.

How Zidovir 100 mg Works ?

Zidovir 100 mg contains Zidovudine, an antiretroviral drug from the nucleoside reverse transcriptase inhibitor (NRTI) class. It works by:

• Blocking Reverse Transcriptase – HIV uses an enzyme called reverse transcriptase to replicate inside human cells. Zidovir inhibits this enzyme, preventing the virus from making copies of itself.
• Reducing Viral Load – By stopping HIV replication, Zidovir lowers the amount of virus in the blood, helping slow disease progression.
• Boosting Immunity – With lower HIV levels, the immune system can function better, reducing the risk of infections and complications.

 Dosage

The dosage of Zidovir (Zidovudine) 100 mg depends on the patient’s age, weight, and medical condition. Below are general guidelines:

1. HIV Treatment

🔹 Dose: 100–200 mg every 6 to 8 hours (or as prescribed)
🔹 Maximum Daily Dose: 500–600 mg in divided doses

2. Prevention of Mother-to-Child Transmission (PMTCT)

• Pregnancy: 100 mg five times daily from week 14 until delivery
• Labor: Given intravenously to the mother

3. Post-Exposure Prophylaxis (PEP)

Dose: 100–300 mg every 8–12 hours, combined with other antiretroviral drugs
🔹 Duration: 28 days

Benefits 

• Suppresses HIV Replication – Zidovir (Zidovudine) blocks the HIV virus from multiplying, helping to slow disease progression.
• Reduces Viral Load – By lowering the amount of virus in the blood, it helps improve overall health.
• Boosts Immune System – Helps the body fight infections by preventing further damage to the immune system.
• Prevents Mother-to-Child Transmission (PMTCT) – Significantly lowers the risk of HIV transmission from mother to baby during pregnancy and childbirth.
• Used in PEP (Post-Exposure Prophylaxis) – Helps prevent HIV infection after accidental exposure, such as needle injuries.
• Delays AIDS Progression – Slows the development of HIV-related complications, improving life expectancy.

Side Effects 

While Zidovir (Zidovudine) can be effective, it may cause side effects. Common and serious side effects include:

Common Side Effects:

• Nausea
• Headache
• Fatigue or Weakness
• Loss of Appetite
• Dizziness

Serious Side Effects:

• Anemia (Low Red Blood Cell Count) – May cause fatigue, weakness, and pale skin.
• Low White Blood Cell Count (Neutropenia) – Increases the risk of infections.
• Liver Problems – Symptoms may include jaundice (yellowing of the skin or eyes), dark urine, and pain in the upper right abdomen.
• Muscle Pain or Weakness – Can be a sign of a condition called myopathy.
• Lactic Acidosis – A rare but serious condition with symptoms like rapid breathing, nausea, and abdominal pain.

Precautions 

Before starting Zidovir (Zidovudine), take the following precautions to ensure safe use:

• Allergic Reactions – Inform your doctor if you have a known allergy to Zidovir or any other components of the medication.
