Introduction
MyHep 400mg is an antiviral medicine made from Sofosbuvir, which is widely used for treating Hepatitis C (HCV). This medicine works by stopping the growth of the hepatitis C virus, reducing the amount of virus in the body, improving liver function, and in many cases, helping to cure the condition.
This detailed guide explains its mechanism, uses, benefits, side effects, and important precautions.
What is MyHep 400mg (Sofosbuvir)?
MyHep 400mg is a Direct-Acting Antiviral (DAA) medicine that contains Sofosbuvir as its active ingredient.
Sofosbuvir is classified as an NS5B polymerase inhibitor. This means it targets a specific protein (NS5B) in the hepatitis C virus that is essential for viral replication. By blocking this protein, the medicine stops the virus from multiplying.
MyHep 400mg is a generic version of Sofosbuvir. It provides the same effectiveness as branded medicines like Sovaldi but at a more affordable cost.
Mechanism of Action of Sofosbuvir
Sofosbuvir works by targeting and blocking the NS5B polymerase enzyme, which is essential for the replication of hepatitis C virus.
1. Inhibition of Viral Replication
The hepatitis C virus uses the NS5B enzyme to copy its genetic material. Sofosbuvir blocks this enzyme and prevents the virus from multiplying.
2. Reduction of Viral Load
By stopping replication, the medicine reduces the amount of virus in the bloodstream. This leads to less liver damage and lower risk of spreading the infection.
3. Achieving Viral Cure (SVR)
Sofosbuvir does not directly kill the virus but prevents its growth. This leads to Sustained Virologic Response (SVR), where the virus becomes undetectable in blood after treatment, which is considered a cure.
Indications for Use
MyHep 400mg is used for the treatment of chronic hepatitis C infection in adults.
Common Uses
- All HCV genotypes (1, 2, 3, 4, 5, 6)

Combination Therapy
Sofosbuvir is usually used with other antiviral medicines such as:
- Ledipasvir
- Velpatasvir
- Daclatasvir
- Ribavirin
The exact combination depends on genotype and liver condition.
Benefits of MyHep 400mg (Sofosbuvir)
1. High Cure Rate
Sofosbuvir-based treatments show cure rates of around 90–98% when used correctly.
