HARVONI treats chronic (lasting longer than 6 months) hepatitis C genotype 1 infection in adults.

Proper Use of this medication

  • Your healthcare professional will determine how long you need to take this medicine. It can be for 8, 12 or 24 weeks.

  • Do NOT stop taking HARVONI without first talking with your healthcare professional.

Usual adult dose:

Overdose:

If you think you have taken too much HARVONI, contact your healthcare professional, hospital emergency department or regional Poison Control Centre immediately, even if there are no symptoms.

Missed dose:

It is important to take HARVONI each day.

Side Effects

These are not all the possible side effects you may feel when taking HARVONI. If you experience any side effects not listed here, contact your healthcare professional.

The most common side effects of HARVONI are tiredness and headache.

Slow heart rate (bradycardia). HARVONI treatment may result in slowing of the heart rate along with other symptoms when taken with amiodarone (Cordarone), a medicine used to treat certain heart problems. In some cases the slow heart rate has led to death or the need for a heart pacemaker. Get medical help right away if you take amiodarone with HARVONI and get any of the following symptoms: near-fainting or fainting, dizziness or lightheadedness, not feeling well, weakness, extreme tiredness, shortness of breath, chest pains, confusion or memory problems.

  • you are allergic to ledipasvir, sofosbuvir (also called Sovaldi when it is used with other medicines without ledipasvir) or any of the other ingredients in this product. (Read also “What are the ingredients in HARVONI?” above.)

  • your doctor says you should use ribavirin with HARVONI and you are pregnant or may become pregnant (or if you are a man whose female partner is pregnant or may become pregnant). Ribavirin may cause birth defects or the death of your unborn baby.
