• If you are currently taking any of the following medicines:
  • rifampicin and rifabutin (antibiotics used to treat infections, including tuberculosis);

  • if you are awaiting a liver transplant;
  • if you have a current or previous infection with the hepatitis B virus, since your doctor may want to monitor you more closely;
• kidney problems or if you are on kidney dialysis, since Harvoni has not been fully tested in patients with severe kidney problems;
• ongoing treatment for HIV infection, since your doctor may want to monitor you more closely.

Talk to your doctor or pharmacist before taking Harvoni if:

• you currently take, or have taken in the last few months, the medicine amiodarone to treat irregular heartbeats, as it may result in a life-threatening slowing of your heart beat. Your doctor may consider different treatments if you have taken this medicine. If treatment with Harvoni is needed, you may require additional heart monitoring.
• you have diabetes. You may need closer monitoring of your blood glucose levels and/or adjustment of your diabetes medication after starting Harvoni. Some diabetic patients have experienced low sugar levels in the blood (hypoglycaemia) after starting treatment with medicines like Harvoni.

Tell your doctor immediately if you currently take, or have taken in the last months, any medicines for heart problems and during treatment you experience:

• slow or irregular heartbeat, or heart rhythm problems;
• shortness of breath or worsening of existing shortness of breath;
• chest-pain;
• light-headedness
• palpitations
• near fainting or fainting

Your doctor will test your blood before, during and after your treatment with Harvoni. This is so that:

• Your doctor can decide if you should take Harvoni and for how long;
• Your doctor can confirm that your treatment has worked and you are free of the hepatitis C virus.

Do not give this medicine to children under 3 years of age. The use of Harvoni in children under 3 years of age has not yet been studied.

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines.

Warfarin and other similar medicines called vitamin K antagonists used to thin the blood. Your doctor may need to increase the frequency of your blood tests to check how well your blood can clot.

Your liver function may change with treatment of hepatitis C and therefore may affect other medications (e.g. medicines used to suppress your immune system, etc.). Your doctor may need to closely monitor these other medicines you are taking and make adjustments after starting Harvoni.

If you are not sure about taking any other medicines, talk to your doctor or pharmacist.

• Do not take any other medicine that contains sofosbuvir, one of the active substances in Harvoni.

Taking Harvoni with any of these may stop your medicines from working properly, or make any side effects worse. Your doctor may need to give you a different medicine or adjust the dose of medicine you are taking.

• Get advice from a doctor or pharmacist if you take medicines used to treat stomach ulcers, heartburn or acid reflux. This includes:

Do not take proton pump inhibitors before Harvoni. Your doctor may give you a different medicine or adjust the dose of the medicine you are taking;
  • H₂-receptor antagonists (such as famotidine, cimetidine, nizatidine or ranitidine). Your doctor may give you a different medicine or adjust the dose of the medicine you are taking.

These medicines can decrease the amount of ledipasvir in your blood. If you are taking one of these medicines your doctor will either give you a different medicine for stomach ulcers, heartburn or acid reflux, or recommend how and when you take that medicine.
