About Daklinza
Daklinza (generic name daclatasvir) is an oral antiviral approved for the treatment of chronic hepatitis C virus (HCV) infection in adults. It belongs to the class of direct-acting antivirals (DAAs) that target a specific viral protein, enabling highly effective virus suppression when combined with other agents. In Singapore, Daklinza is prescribed as part of genotype-specific regimens, often together with sofosbuvir or other DAAs, to achieve a sustained virologic response (SVR). The tablet is supplied at a fixed dose of 60 mg once daily, and treatment duration is determined by the viral genotype, presence of cirrhosis, and prior therapy history. Although primarily indicated for HCV, the drug’s mechanism has prompted investigation of additional antiviral applications under strict clinical supervision.
What is Daklinza?
Daklinza is the brand name for daclatasvir, a small-molecule inhibitor that blocks the non-structural protein 5A (NS5A) of hepatitis C virus. NS5A is essential for viral RNA replication and assembly of infectious particles, so interrupting its function halts the replication cycle. The product is marketed by Bristol-Myers Squibb and was first approved by the U.S. Food and Drug Administration in 2015 for use in combination therapy. In Singapore, the Medicines Health Regulatory Authority (MHRA) has granted registration for several genotype-guided combinations, reflecting the drug’s role in the modern, interferon-free HCV treatment landscape. While generic versions containing the same active ingredient are available, Daklinza remains the reference product with a well-characterized safety profile and extensive post-marketing data.
How Daklinza Works
Daclatasvir binds to a conserved region of the NS5A protein, inducing a conformational change that prevents the formation of the replication complex required for viral RNA synthesis. By destabilising this complex, the drug reduces the production of new viral genomes and impairs the assembly of virions. Because NS5A participates in both replication and assembly, inhibition yields a rapid decline in viral load, often within the first week of therapy.
Pharmacokinetically, Daklinza is rapidly absorbed after oral administration, reaching peak plasma concentrations in roughly 4 hours. Food does not markedly affect exposure, allowing flexibility in dosing relative to meals. The compound is extensively metabolised by the cytochrome P450 3A4 (CYP3A4) enzyme system, generating metabolites that are cleared primarily via bile. Its half-life averages 12-15 hours, supporting once-daily dosing. The reliance on CYP3A4 explains many drug-drug interactions, especially with strong inducers or inhibitors of this pathway. Because the drug is not eliminated renally, dose adjustment is unnecessary in patients with renal impairment, but hepatic function must be considered when co-administered with agents that alter CYP3A4 activity.
The therapeutic potency of Daklinza arises from its high affinity for NS5A (IC₅₀ ≈ .3 nM) and its ability to retain activity across all major HCV genotypes. When paired with a polymerase inhibitor such as sofosbuvir, the regimen targets two distinct steps of the viral life cycle, dramatically increasing the likelihood of achieving SVR-a virologic cure defined as undetectable HCV RNA 12 weeks after treatment completion.
Why Daklinza Is Used for Infectious-Disease Conditions
-
Chronic HCV genotype 1 infection - Studies comparing 12-week regimens of daclatasvir + sofosbuvir to standard interferon-based therapy demonstrate SVR rates exceeding 95 % in non-cirrhotic patients. By inhibiting NS5A, Daklinza suppresses the dominant replication machinery of genotype 1, allowing the polymerase inhibitor to clear residual viral genomes.
-
HCV genotype 2 and 3 - Although genotypes 2/3 respond well to sofosbuvir alone, adding daclatasvir shortens treatment to eight weeks for many patients, reducing exposure-related costs and improving adherence. The combination leverages NS5A inhibition to counteract the higher replication efficiency observed in genotype 3.
-
Compensated cirrhosis (any genotype) - Cirrhotic livers present a more hostile environment for antiviral penetration. Clinical trials show that extending therapy to 24 weeks with daclatasvir + sofosbuvir restores SVR rates to >90 % in this subgroup, illustrating how sustained NS5A blockade can overcome fibrosis-related barriers.
-
HCV/HIV co-infection - Co-infected individuals often receive antiretroviral regimens that interact with CYP3A4. Carefully selected combinations-including dose adjustments of daclatasvir-have produced cure rates comparable to monoinfected patients, highlighting the drug’s flexibility when managed by an experienced clinician.
-
Patients intolerant to ribavirin - Ribavirin, once a cornerstone of HCV therapy, carries a high burden of hemolytic anemia. Daklinza-based regimens eliminate the need for ribavirin in most scenarios, offering a safer alternative while maintaining high cure percentages.
The consistent theme across these indications is the drug’s ability to directly cripple a viral protein that the virus cannot easily mutate without losing fitness. Consequently, resistance emergence is rare when daclatasvir is used as part of a synergistic combination, aligning with current international treatment guidelines that recommend interferon-free, all-oral DAA regimens.
Off-Label and Investigational Uses of Daklinza
Clinical investigations have explored daclatasvir in combination with other DAAs for HCV reinfection after liver transplantation. Small-scale studies suggest that an intensified regimen containing daclatasvir can achieve rapid viral suppression in the early post-transplant period, a critical window where immunosuppression heightens replication risk. Another line of research examines daclatasvir’s NS5A inhibition in novel flaviviruses that share conserved replication domains; in vitro data indicate modest activity, but human trials remain absent. Off-label use only under qualified healthcare provider supervision and should be considered experimental.
Is Daklinza Right for You?
Candidates for Daklinza-based therapy typically include adults with confirmed chronic HCV infection who have no contraindication to NS5A inhibition. Patients who have previously failed an interferon-based regimen, those with renal impairment, and individuals seeking an interferon-free option often benefit most. As noted above, severe hepatic impairment (Child-Pugh C) is a circumstance where dosing may need adjustment or alternative agents are preferred. Likewise, anyone receiving strong CYP3A4 inducers-such as rifampicin, carbamazepine, or St. John’s wort-should avoid co-administration because therapeutic levels of daclatasvir may fall below efficacy thresholds. Pregnant or lactating women are excluded from treatment due to limited safety data. In special populations like the elderly, no dose reduction is required, but clinicians should monitor for drug interactions because polypharmacy is common. Ultimately, a thorough evaluation of genotype, liver disease stage, and concurrent medications determines whether Daklinza is the optimal choice.
Taking Daklinza Effectively
Daklinza is taken as a single 60 mg tablet, ideally at the same time each day to maintain steady plasma concentrations. Food does not interfere with absorption, so the dose can be swallowed with or without meals, which simplifies scheduling for busy adults. If a dose is missed and the next scheduled dose is more than 12 hours away, the missed tablet should be taken immediately; otherwise, skip it and resume the regular timing to avoid accidental double dosing. Adherence is paramount: missing several doses can permit viral replication and increase the risk of resistance. Setting daily alarms on a smartphone, linking the dose to a routine activity (e.g., brushing teeth), or using a pill-organiser can mitigate forgetfulness. When traveling, keep tablets in original, child-proof packaging and carry a copy of the prescription to satisfy customs in Singapore and abroad. Avoid storing the medication in humid environments; a cool, dry place within reach of the patient ensures potency throughout the treatment course.
Understanding Side Effects and How to Manage Them
Most patients tolerate Daklinza well, but the drug’s mechanism can provoke fatigueheadache, and nausea-symptoms that often resolve spontaneously within the first two weeks. These effects stem from transient alterations in hepatic metabolism and central nervous system signalling as the body adjusts to reduced viral activity. To alleviate fatigue, maintaining regular sleep patterns and limiting caffeine intake can be helpful. Headaches respond to over-the-counter acetaminophen, provided liver function remains stable; ibuprofen should be used cautiously if hepatic enzymes are elevated. Nausea may improve with modest meals or ginger tea, and anti-emetics reserved for severe cases.
A less common but clinically relevant concern is elevated liver enzymes. While Daklinza itself is not hepatotoxic, rapid viral clearance can unmask underlying liver injury. Routine monitoring of ALT, AST, and bilirubin at baseline and every four weeks during therapy enables early detection. If transaminases rise more than five-fold the upper limit of normal, the provider may pause treatment and investigate other causes such as alcohol use or concomitant hepatotoxic drugs.
Serious adverse events are rare but include symptomatic bradycardia when co-administered with certain anti-arrhythmics, and severe hypersensitivity reactions manifesting as rash, facial swelling, or dyspnea. Should any of these arise, seek immediate medical attention; the drug should be discontinued promptly. Patients experiencing persistent jaundice, dark urine, or severe abdominal pain should also contact their clinician without delay, as these may signal decompensated liver disease.

Frequently Asked Questions
-
How long does treatment with Daklinza typically last? The duration depends on HCV genotype, presence of cirrhosis, and whether the drug is combined with sofosbuvir or other DAAs. Most regimens span 12 weeks, but patients with compensated cirrhosis or certain genotype 3 infections may require 24 weeks to maximise cure rates.
-
Can Daklinza be taken with alcohol? Moderate alcohol consumption does not directly interfere with daclatasvir’s pharmacology. However, excessive drinking can worsen liver disease and undermine treatment success, so clinicians usually advise limiting intake while on therapy.
-
What laboratory tests are needed before starting Daklinza? Baseline assessments include HCV RNA quantification, genotype determination, liver function tests (ALT, AST, bilirubin), renal function, and a review of current medications to identify potential CYP3A4 interactions.
-
Is breastfeeding safe while on Daklinza? Data on daclatasvir excretion into human milk are insufficient. Because of the theoretical risk to the infant, most guidelines recommend avoiding breastfeeding during treatment unless the benefits clearly outweigh potential harm.
-
How does Daklinza compare with other NS5A inhibitors like ledipasvir? Both agents target the same viral protein, but daclatasvir exhibits pan-genotypic activity, whereas ledipasvir is primarily effective against genotype 1. Consequently, Daklinza offers greater flexibility in regimens that address multiple genotypes.
-
Will I need a follow-up visit after completing therapy? Yes. A post-treatment HCV RNA test is typically performed 12 weeks after the last dose to confirm sustained virologic response. Additional liver imaging may be recommended if advanced fibrosis was present before treatment.
-
Can I switch from a sofosbuvir-based regimen to Daklinza alone? Monotherapy with daclatasvir is insufficient for viral eradication; it must be paired with at least one other DAA. Switching without a suitable companion drug risks treatment failure and resistance.
-
What should I do if I experience a rash while on Daklinza? Mild, localized rash can be managed with antihistamines and moisturisers. If the rash spreads, involves mucous membranes, or is accompanied by fever, discontinue the medication and seek urgent medical care.
-
Is dose adjustment necessary for elderly patients? No routine dose reduction is required for older adults. Nonetheless, careful review of concomitant medicines is essential because polypharmacy increases the likelihood of CYP3A4-mediated interactions.
-
How quickly can I expect my viral load to drop? In most patients, HCV RNA levels decline by more than 2-log₁₀ within the first week of therapy, reflecting the rapid impact of NS5A inhibition on viral replication.
