Dosage for hepatitis C
Epclusa is a fixed dosing regimen in adults, meaning two drugs are combined into one dosage form. The dosage of Epclusa for adults with hepatitis C is one 400 mg/100 mg tablet taken once per day.
If you have trouble swallowing tablets, your doctor may prescribe Epclusa oral pellets for you. The typical dose of Epclusa oral pellets is two packets of 200 mg/50 mg once per day. By taking two packets, you’ll receive the same total daily dose as the oral tablets.
Epclusa is approved to treat children ages 3 years and older. The dosing regimen for children depends on your child’s weight.

Epclusa is meant to be a short-term treatment. Typically, your doctor will prescribe Epclusa for a 12-week course or a 24-week course. How long you take Epclusa can depend on the type of hepatitis C and other conditions you have. Talk with your doctor if you’d like more information on how long you need to take Epclusa.
The Epclusa dosage your doctor prescribes will depend on several factors. These include:
- the type and severity of the condition you’re taking Epclusa to treat
- the form of Epclusa you take
- your weight
- how well some other antiviral medications work for you, such as ribavirin
Other medical conditions you have can also affect your Epclusa dosage, such as liver scarring and liver damage. If you have certain stages of liver scarring, your doctor may decide to treat you with Epclusa for 24 weeks instead of the usual 12 weeks.
Epclusa comes as both an oral tablet and oral pellets. Both of these forms are taken by mouth. Your Epclusa dose should be taken exactly as your doctor prescribes. You can take Epclusa oral tablets or oral pellets with or without food.
If you have trouble swallowing tablets, see this article for tips on how to take this form of medication. You can also talk with your doctor or pharmacist.
ACCESSIBLE DRUG LABELS AND CONTAINERS
Some pharmacies offer labels with large print, braille, or a code you scan with a smartphone to convert text to speech. If your local pharmacy doesn’t have these options, your doctor or pharmacist might be able to recommend a pharmacy that does.
If you’re having trouble opening medication bottles, ask your pharmacist about putting Epclusa in an easy-open container. They also may recommend tools that can make it easier to open bottles.
Epclusa works best when taken exactly as prescribed by your doctor. If you miss a dose of Epclusa, you should take your dose as soon as you remember. If it’s nearly time for your next scheduled Epclusa dose, skip your missed dose and continue taking Epclusa on your usual schedule. It is important that you do not take two doses of Epclusa at once as this may increase your risk for serious side effects.
It may be helpful to take your Epclusa dose at the same time every day.
To help make sure that you don’t miss a dose, try using a medication reminder. This can include setting an alarm or putting a note where you’ll see it, such as on your bathroom mirror or bedside table. You could also download a reminder app on your phone.
If you use more Epclusa than your doctor prescribes, you may develop harmful effects.
It’s important that you do not use more Epclusa than your doctor advises.
