Velpatasvir is a direct-acting antiviral medication used to treat chronic hepatitis C virus infection.
Velpatasvir is an antiviral medicine that belongs to a class of drugs called NS5A inhibitors. It works against the hepatitis C virus, helping to stop the virus from multiplying in the body. In Hong Kong, velpatasvir is found in products such as Velpanat that are approved by the Department of Health (Hong Kong SAR).
Velpatasvir is marketed in Hong Kong primarily as Velpanat, a tablet that contains the active ingredient alone or in combination with other antivirals. The tablets are available in standard strengths that match the dosage used in clinical studies. Velpanat is sold under a brand name, while the underlying compound velpatasvir is also available as a generic ingredient in other locally approved products. Most formulations come as oral tablets that can be taken with water; some combinations may include a liquid version for patients who have difficulty swallowing pills.
The medication helps to clear the virus from the bloodstream, which can reduce liver inflammation and lower the risk of long-term complications such as liver failure or liver cancer.
Velpatasvir blocks a protein called NS5A that the hepatitis C virus needs to build new viral particles. By stopping this protein, the drug prevents the virus from copying itself, allowing the immune system to clear the infection more effectively. The antiviral effect begins soon after the first dose, but a full treatment course typically lasts several weeks to achieve the best results.
Most people who take velpatasvir-containing medicines notice only mild and temporary effects. Typical experiences may include:
These symptoms usually resolve on their own and do not require medical intervention.
Rarely, more severe problems can occur. Seek urgent medical help if you notice:
These signs may indicate an allergic reaction that needs immediate attention.

Velpatasvir can interact with other medicines and substances. Important points to remember:
For a complete list of possible interactions, refer to the patient information leaflet specific to the product you are using.
Store velpatasvir tablets in a cool, dry place away from direct sunlight and out of reach of children. The typical treatment period for hepatitis C is several weeks, but the exact length depends on the specific product and the patient’s medical history. Always follow the instructions printed on your medication’s label, as formulations such as Velpanat may differ in strength or combination with other antivirals. For detailed usage, dosing, and administration, refer to your specific medication’s information.
