Daclahep is a single dose therapy, used in combination not alone

Daclahep tablets are containing Daclatasvir, an anti-viral compound useful in the treatment of chronic hepatitis C viral infection caused by genotypes III

Daclahep targets HBV NS5A to suppress the viral multiplication; it is applicable in the strength of 60mg


Brand name: Daclahep

Active ingredients: Daclatasvir

Strength: 60MG

Mfg: Hetero healthcare

Package: 28 tablets in a container

Classification: Anti-viral agent


Prescribing information of Daclahep

Daclahep is highly effective against HCV genotype III; there is no continue side effects occur

One of the major disadvantage occur in Daclatasvir therapy; while combining with sofosbuvir there is a chance of reducing virological response in HCV genotype III patients

The main indication of Daclahep, where it has prescribed frequently for;

Chronic hepatitis C viral infection caused by genotype III


Mechanism of Daclahep

The mechanism of action involved in Daclahep is very simple, it is NS5A inhibitor, a protein which is essential for hepatitis C viral production.

Daclahep after metabolism occurs; it exhibits NS5A inhibitory activity against Hepatitis C virus and causes termination of viral production and virion aggregation



The absorption of Daclahep tablet held rapidly, reaches peak plasma concentration within 2 hours after drug intake

The oral bioavailability of Daclahep tablet reaches 67%



Daclahep is highly bound to the human plasma protein around 99%

The volume of distribution at steady state level occurs 47L



Daclahep containing Daclatasvir is a CYP3A substrate, which is responsible for metabolism



The route of elimination;

Feces: 88%

Urine: 6.6%

The terminal half life period of Daclahep is relatively occurred at 12 to 15 hours


How to take Dacihep  tablets

Daclahep should be administered with or without food; Daclahep tablets are used as single dose therapy


Dosage regimens

The usual recommended dosage of Daclahep is 60mg, should be given in combination with sofosbuvir

Daclahep should be used in HCV genotype I or III infections

Genotype III:

In decompensated cirrhosis:

The usual dosage is 60mg of Daclahep with 400mg of sofosbuvir and weight based ribavirin should be taken as single dose

The safety and effectiveness of Daclahep tablet in pediatric patients has not been established with <18 years

In adult patient without cirrhosis or with compensated cirrhosis:

The recommended dosage is 60mg of Daclahep with 400mg of sofosbuvir should be given as a single dose

Genotype I:

In adult patient without cirrhosis or with compensated cirrhosis:

The recommended dosage is 60mg of Daclahep with 400mg of sofosbuvir should be given as a single dose

In decompensated cirrhosis:

The usual dosage is 60mg of Daclahep with 400mg of sofosbuvir and weight based ribavirin should be taken as single dose


Dosage modification:

Daclahep with strong CYP3A inhibitors used, the dosage of Daclahep should be reduced into 30mg

With moderate CYP3A, the dosage of Daclahep should be 90mg as a single dose

With strong CYP3A inducers, usage of Daclahep tablet is contraindicated


Daclahep caused side effects


Elevation of lipase





HBV reactivation


Drug interaction

Strong CYP3A inhibitors: clarithromycin, itraconazole, posaconazole, voriconazole, ketaconazole, atazanavir/ritonavir

Moderate CYP3A inducers: dexamethasone, rifapentine, modafinil, efavirenz, Bosentan

Moderate CYP3A inhibitors: ciprofloxacin, atazanavir, erythromycin, verapamil, diltiazem, fluconazole

Daclahep with amiodarone cause symptomatic bradycardia

Daclahep is a P-gp, BCRP, organic anion transporting polypeptide inhibitors, whereas co administration of these drugs with Daclahep causes increasing the systemic exposure of these drugs, which could elevate the adverse effects

Daclahep combined with acetyl sulfisoxazole may causes reduction in metabolism of Daclahep

Daclahep with lipid lowering drugs causes increasing the effect of concentration of lipid lowering drugs

Daclahep is a CYP3A substrate, while using moderate or strong CYP3A inducers with Daclahep tablets may causes depletion of plasma levels and therapeutic effects of Daclahep

Daclahep concurrent use with CYP3A strong inhibitors causes elevation of plasma level of Daclahep


Food drug interaction

No food drug interaction occur, consult with physician about diet while using Daclahep tablet

Whereas herbal product likes st. Johns wort with Daclahep tablets causes loss of therapeutic effect of Daclahep


Possible contraindications

Daclahep concurrent use with CYP3A strong inducers, leads to depletion of virological response of Daclahep

Contraindicated drugs like;

Herbal product st Johns wort

Anti-mycobacterials rifampin

Anti convulsants phenytoin, Phenobarbital, carbamazepine

Anaphylactic reactions


Safety measures

Some adverse reactions occurred due to drug interaction, it may include as;

  • Severe adverse effects occurred due to concomitant drugs
  • Lack of therapeutic effect of Daclahep and cause advancement of resistance

The safety and effectiveness of Daclahep in liver transplanted patients has not been established

While using with amiodarone, causes serious bradycardia it is controlled by providing counsel to the suspected patients, or prescribe alternative medicines

Care should be taken while using in renal and hepatic impairment patients, because of no dosage adjustment preferred

Patients, who are having HCV/HBV co infection, have chance of reactivation of HBV infection after completion of therapy
