What is DAKLINZA used for

DAKLINZA is used to treat chronic (long-lasting) infection with the hepatitis C virus (HCV) genotypes 1, 2 and 3. DAKLINZA is used with other medicines that also treat chronic HCV infection.

People with hepatitis C infection have the virus in their blood and in their liver.

DAKLINZA should not be taken alone.

DAKLINZA has not been studied in children under 18 years of age.

How does DAKLINZA work

DAKLINZA used with other medicines has been shown to cure chronic HCV infection in most patients. Cure means the HCV is removed from your blood (remains at an undetectable level) for 3 months after finishing all treatment.

DAKLINZA blocks a protein from the virus that is needed to make new virus, and this helps to lower the virus level in your body.

What are the ingredients in DAKLINZA

Medicinal ingredients: Daclatasvir tablets, 30, 60 mg (as daclatasvir dihydrochloride).

Non-medicinal ingredients: Anhydrous lactose, croscarmellose sodium, magnesium stearate, microcrystalline cellulose, Opadry Green and silicon dioxide. The Opadry Green contains the following inactive ingredients: FD & C blue #2 / indigo carmine aluminum lake, hypromellose, iron oxide (yellow), polyethylene glycol 400 and titanium dioxide.

DAKLINZA comes in the following dosage forms:

DAKLINZA is available as tablets. Each tablet contains daclatasvir as the active ingredient. Tablets are available in two strengths.
