In this session, we will be discussing the consumer medication information for ledipasvir and sofosbuvir, trade name HarvoniTM.

What it’s for & How to take

Ledipasvir/sofosbuvir is a combination of 2 antiviral medications that are used to treat chronic hepatitis C. These two medications work together to decrease the amount of hepatitis C virus in the body while also stopping the virus that causes hepatitis C from spreading in the body.

Hepatitis means inflammation of the liver. Toxins, certain drugs, some diseases, heavy alcohol use, and bacterial and viral infections can all cause hepatitis. Hepatitis is also the name of a family of viral infections that affect the liver. The most common types are Hepatitis A, Hepatitis B, and Hepatitis C.

Hepatitis C is a contagious liver disease that ranges in severity from a mild illness lasting a few weeks to a serious, lifelong illness that attacks the liver. The Hepatitis C virus is spread primarily through contact with the blood of an infected person.

Ledipasvir/sofosbuvir may treat hepatitis C in the person it is prescribed for, it is not known if this medication will prevent the spread of hepatitis C to other people.

Ledipasvir/sofosbuvir is available as a tablet and is usually ordered to be taken once daily, with or without food. This medication works best when a constant level is maintained in your body. Take your dose at the same time each day.

If you are taking antacids containing aluminum or magnesium, such as MaaloxTM or MylantaTM, take them at least 4 hours before or after your dose of ledipasvir/sofosbuvir. The antacid may decrease the absorption of this medication, and it may not work as well.

If you miss a dose, take it as soon as you remember. If it is near the time of your next dose, skip it and continue with your normal dose time. Do not take a double dose to make up the missed dose.

The length of your treatment will be anywhere between 8 – 24 weeks. Your duration of treatment will depend on your condition, response to treatment, and severity of side effects. Do not stop taking your medication without talking to your doctor first.

This medication is sometimes used to treat other conditions. Talk with your doctor of pharmacist if you are prescribed this medication to treat something that is not listed here.
