The Evolution of Hepatitis C Treatment
For many years, the standard treatment for hepatitis C (HCV) was a regimen involving interferon injections and ribavirin pills. This approach was lengthy, often requiring treatment for 24 to 48 weeks, and was associated with significant, and often severe, side effects, including flu-like symptoms, depression, and low blood cell counts. The cure rates were also significantly lower, sometimes as low as 50%, depending on the viral genotype.
The introduction of direct-acting antivirals (DAAs) marked a dramatic turning point in the management of HCV. These newer oral medications specifically target and block the proteins the virus needs to replicate and survive, making them far more effective and better tolerated than their predecessors. Today, DAAs are considered the standard of care for virtually all patients with HCV.
Key Direct-Acting Antiviral Medications
Instead of a single "Hep C pill," there is a selection of oral DAA medications, each combining two or three active drug ingredients to effectively attack the virus. The choice of medication is based on the patient's specific HCV genotype, prior treatment history, and liver health. Some of the most common and widely used DAA treatments include:
Epclusa (Sofosbuvir/Velpatasvir)
Epclusa is a combination pill that contains sofosbuvir, a polymerase inhibitor, and velpatasvir, an NS5A inhibitor. It is known for its pangenotypic coverage, meaning it can treat all six major genotypes of HCV. Treatment typically lasts 12 weeks for most patients and boasts a high success rate. It is also one of the few options for patients with decompensated cirrhosis, though it must be used in combination with ribavirin in these cases.
Mavyret (Glecaprevir/Pibrentasvir)
Mavyret is another highly effective pangenotypic treatment that combines glecaprevir and pibrentasvir. A major advantage of Mavyret is its short treatment duration, with some treatment-naive patients needing only 8 weeks of therapy. It is an excellent first-line option for many patients without cirrhosis or with compensated cirrhosis. However, it is not recommended for patients with moderate to severe liver impairment.
Harvoni (Ledipasvir/Sofosbuvir)
Harvoni was one of the first interferon-free DAAs approved for certain genotypes. It combines ledipasvir, an NS5A inhibitor, and sofosbuvir. While highly effective, it only covers genotypes 1, 4, 5, and 6. A generic version is also available, which can help with affordability.
Vosevi (Sofosbuvir/Velpatasvir/Voxilaprevir)
Vosevi is a triple-combination DAA containing sofosbuvir, velpatasvir, and voxilaprevir. It is typically reserved for adult patients who have failed previous DAA treatments and is effective against all HCV genotypes. Treatment with Vosevi is also generally a 12-week course.
Common Side Effects of DAAs
While DAAs are much better tolerated than older therapies, they are not entirely without side effects. Most are mild and manageable. Common side effects reported across DAA medications include:
- Headache
- Fatigue
- Nausea
- Diarrhea
- Insomnia
More serious, though rare, side effects can include a reactivation of the hepatitis B virus (HBV) in patients who have both HBV and HCV. For this reason, a healthcare provider will screen patients for HBV before starting treatment. Patients should always report any persistent or severe side effects to their doctor.
Comparison of Major Hepatitis C Medications
| Feature | Epclusa | Mavyret | Harvoni | Vosevi |
|---|---|---|---|---|
| Genotype Coverage | Pangenotypic (1-6) | Pangenotypic (1-6) | Genotypes 1, 4, 5, 6 | Pangenotypic (1-6) |
| Standard Duration | 12 weeks | 8 weeks (treatment-naive) | 12-24 weeks | 12 weeks |
| Key Ingredients | Sofosbuvir/Velpatasvir | Glecaprevir/Pibrentasvir | Ledipasvir/Sofosbuvir | Sofosbuvir/Velpatasvir/Voxilaprevir |
| Use in Decompensated Cirrhosis | Yes (with ribavirin) | No | Yes (with ribavirin) | Not recommended |
| Primary Use | First-line treatment | First-line treatment (short duration) | First-line treatment for specific genotypes | Salvage therapy for prior treatment failure |
The Path to a Cure
With high cure rates now achievable with DAAs, hepatitis C is no longer the lifelong, debilitating condition it once was. Patients can often complete treatment in as little as 8 to 12 weeks, with relatively few side effects. The success of the treatment is confirmed by a blood test three months after completion, checking for a sustained virologic response (SVR), or no detectable virus. If SVR is achieved, the patient is considered cured.
Ultimately, the choice of the right "Hep C pill" is a medical decision made in consultation with a healthcare provider, who will consider the patient's individual circumstances to select the most appropriate DAA regimen. Regular monitoring and adherence to the treatment plan are crucial for achieving the best possible outcome.

Conclusion
The question of "what is the Hep C pill called?" highlights a crucial shift in medical history. The era of painful interferon injections has been replaced by an array of highly effective, well-tolerated oral medications known as direct-acting antivirals (DAAs). Pills such as Epclusa, Mavyret, and Harvoni offer cure rates exceeding 95%, transforming hepatitis C from a chronic illness into a curable condition for the vast majority of patients. By targeting the virus's replication process, these medications provide a shorter, simpler, and more successful path to recovery. Consulting a healthcare professional is the first step to determining the right DAA regimen for a patient's specific needs, leading to a potential cure in just a few months.
