Daclatasvir is used to treat specific chronic viral infections affecting the liver. Stopping the virus from copying itself, the medicine helps the body clear the infection.
Daclatasvir is the active compound in antiviral tablets such as Natdac and Daclatasvir. It belongs to a class of drugs called NS5A inhibitors, which block a protein the hepatitis C virus needs to grow.
These medicines work together with other antivirals to keep the virus from copying itself, helping your liver stay healthier. In Australia, daclatasvir is one of the key ingredients that clinicians select for chronic hepatitis C treatment.
The hepatitis C virus, when living in your body for months or years, can cause fatigue, abdominal discomfort, or swollen legs. Daclatasvir-containing regimens are used to address this infection and reduce the amount of virus in your blood.
You may encounter daclatasvir if you have:
Typically, adults with hepatitis C who are not pregnant receive daclatasvir as part of a combination therapy. Younger patients may also be considered, depending on their overall health.
After you swallow a tablet, daclatasvir is absorbed into your bloodstream and travels to the liver, where hepatitis C lives. There it attaches to the NS5A protein, a building block the virus uses to assemble new copies of itself. Blocking that protein stops the virus from producing new particles, giving your immune system a better chance to clear the infection.
Women who are pregnant, planning to become pregnant, or breastfeeding should use caution with daclatasvir because safety data are limited. People with severe liver impairment may also need a different approach.
Interactions to watch for include:
Always check the specific medication label for a complete list of possible interactions.
Older adults and people with existing liver disease tend to experience side effects more often. Those taking multiple medications that affect liver enzymes may also be at higher risk.
Keep daclatasvir tablets in their original container, away from excess heat, moisture, and direct sunlight. Most products are stable at room temperature (below 30 °C). Treatment duration can vary, but many courses last 8-12 weeks.
For detailed usage, dosing, and administration, refer to the specific medication's clinical information.
