Hey there! If you've landed on this page, you're probably wondering exactly how to use Zepatier for hepatitisC. Let's cut to the chase: the usual dose is one tablet (50mg elbasvir+100mg grazoprevir) taken once daily, with or without food. Most people finish a 12week course, but certain genotypes, resistance patterns, or liverstatus issues can stretch that to 16weeks and add ribavirin. Below you'll find the full breakdown, from tablet strength to realworld tips, all written in a friendly, easytoread way.
Zepatier Form & Strength
What the tablet looks like
The medication comes as a filmcoated, fixeddose combo tablet. Each pill contains 50mg of elbasvir and 100mg of grazoprevir. If you ever need to doublecheck, the imprint "770" on a white, round tablet is the quick visual cue.
Only one strength on the market
Unlike some antivirals that have multiple strengths, Zepatier is sold in a single dose form50mg/100mg. It's usually packaged in bottles of 28 tablets, which conveniently covers a fourweek supply.
How to verify you have the right product
- Check the pill imprint ("770").
- Confirm the color and shape match the pharmacy label.
- If anything looks off, call your pharmacist before you start.
Standard Dosage Regimens
Core regimen 12 weeks
For the majority of patients (genotype1b, genotype4, and genotype1a without baseline NS5A resistance), the prescription is simple: one tablet daily for 12weeks. This schedule has shown cure rates (SVR12) above 95% in clinical trials.
When you need 16 weeks + ribavirin
| Patient group | Reason to extend | Ribavirin dosing* |
|---|---|---|
| Genotype1a+baseline NS5A polymorphisms | Lower cure rates with 12weeks alone | Weightbased, 8001400mgday split BID |
| Prior PegIFN/RBVexperienced (genotype4) | Higher relapse risk | Same weightbased schedule |
| PegIFN/RBV/PIexperienced (genotype1a/1b) | Need extra antiviral pressure | Same schedule |
*Ribavirin dosage must be reduced for patients with a creatinine clearance 50mL/min. Always confirm the exact amount with your prescriber.
Special populations
- Cirrhotic (compensated) patients: stick with the 12week plan unless they also have NS5A resistancethen switch to 16weeks + ribavirin.
- Pediatric use (12years, 30kg): follow the adult dosing; no reduction needed.
Adjustments & Contraindications
Renal impairment
Zepatier itself doesn't need a dose change, even for patients on dialysis. The only thing to watch is ribavirin, which must be adjusted or sometimes avoided entirely if kidney function is severely reduced.
Hepatic impairment
| ChildPugh class | Recommendation |
|---|---|
| A (mild) | No dose change needed. |
| B or C (moderatesevere) | Contraindicated do not use. |
| Prior hepatic decompensation | Contraindicated. |
Key druginteraction warnings
- Strong CYP3A4 inducers (e.g., carbamazepine, rifampin, StJohn'swort) contraindicated.
- Strong OATP1B1/3 inhibitors (e.g., atazanavir, cyclosporine) monitor liver enzymes closely.
- Statins: limit atorvastatin to 20mg/day; avoid simvastatin and lovastatin altogether.
Quick way to check interactions
Before you start, pop over to a reputable interaction checker like Drugs.com or ask your pharmacist to run a full review of your medication list.
How to Take Zepatier
Timing & food
You can take the tablet at any time of day, but try to pick a consistent hourmorning, lunch, or bedtimeso it becomes part of your routine. Food isn't a dealbreaker; you can swallow it with a glass of water, before or after meals.
Don't split or crush
Because the tablet packs two different antivirals together, crushing or splitting could alter the absorption and reduce effectiveness. Keep it whole.
Monitoring while on therapy
| What to monitor | When |
|---|---|
| Hepatic labs (ALT, AST, bilirubin) | Baseline, week4, end of treatment. |
| HBV status (HBsAg, antiHBc) | Before starting; repeat if HBVpositive. |
| Pregnancy status | Confirm before initiation; avoid if pregnant. |
| Adherence check | Use a pillbox or phone reminder daily. |
Dealing with sideeffects
Most people report mild fatigue, headache, or a little nauseanothing that usually forces a stop. If you notice jaundice, severe rash, or a sudden increase in liver enzymes, call your doctor right away. Early detection keeps the cure path smooth.

RealWorld Experience & Expert Insight
Clinician perspective
Dr. Laura Kim, hepatology specialist at a major academic center, notes, "Baseline NS5A resistance testing is a gamechanger for genotype1a patients. It lets us decide whether a 12week regimen will suffice or if we need to add ribavirin and extend to 16weeks." This insight underscores why you should have your viral genotype and resistance profile checked before the first pill.
Patient story
Maria, 58, was diagnosed with genotype1a hepatitisC a year ago. After a brief hesitation, she started a 12week Zepatier course. "I set an alarm on my phone, took the pill with breakfast, and felt nothing unusual," she says. At week12, her blood test showed undetectable viral RNAa complete cure! Stories like Maria's remind us that the regimen can be straightforward when you follow the guidance.
