If Epclusa has been prescribed for your child, please note that all the information in this leaflet is addressed to your child (in this case please read “your child” instead of “you”).

• If you are allergic to sofosbuvir, velpatasvir or any of the other ingredients of this medicine (listed in section 6 of this leaflet).

If this applies to you, do not take Epclusa and tell your doctor immediately.

• If you are currently taking any of the following medicines:
  • rifampicin and rifabutin (antibiotics used to treat infections, including tuberculosis);
  • St. John’s wort (herbal medicine used to treat depression);
  • carbamazepine, phenobarbital and phenytoin (medicines used to treat epilepsy and prevent seizures).

Talk to your doctor if you:

• have liver problems other than from hepatitis C, for instance
  • if you have a current or previous infection with the hepatitis B virus, since your doctor may want to monitor you more closely;
  • if you have had a liver transplant
• have kidney problems or if you are on kidney dialysis, since Epclusa has not been fully tested in patients with some severe kidney problems;
• are taking treatment for human immunodeficiency virus (HIV) infection, since your doctor may want to monitor you more closely.

Talk to your doctor or pharmacist before taking Epclusa 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 Epclusa 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 medicine after starting Epclusa. Some diabetic patients have experienced low sugar levels in the blood (hypoglycaemia) after starting treatment with medicines like Epclusa.

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 Epclusa. This is so that:

• Your doctor can decide if you should take Epclusa 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 Epclusa in patients under 3 years of age has not 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 are 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 Epclusa.

If you are not sure talk to your doctor or pharmacist.

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

Tell your doctor or pharmacist if you are taking any of the medicines below:

• amiodarone used to treat irregular heartbeats;
• rifapentine (antibiotic used to treat infections, including tuberculosis);
• oxcarbazepine (medicine used to treat epilepsy and prevent seizures);
• tenofovir disoproxil fumarate or any medicine containing tenofovir disoproxil fumarate, used to treat HIV infection and chronic hepatitis B;
• efavirenz used to treat HIV infection;
• digoxin used to treat heart conditions;
• dabigatran used to thin the blood;
• modafinil used to treat sleep disorders;
• rosuvastatin or other statins used to treat high cholesterol.

Taking Epclusa 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. This change could be to Epclusa or another medicine you are taking.

• Get advice from a doctor or pharmacist if you take medicines used to treat stomach ulcers, heartburn or acid reflux as they can decrease the amount of velpatasvir in your blood. These medicines include:
  • antacids (such as aluminium/magnesium hydroxide or calcium carbonate). These should be taken at least 4 hours before or 4 hours after Epclusa;
  • proton pump inhibitors (such as omeprazole, lansoprazole, rabeprazole, pantoprazole and esomeprazole). Epclusa should be taken with food 4 hours before using a proton pump inhibitor.
  • H₂-receptor antagonists (such as famotidine, cimetidine, nizatidine or ranitidine). If you need high doses of these medicines your doctor may give you a different medicine instead or adjust the dose of the medicine you are taking.

These medicines can decrease the amount of velpatasvir 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.

The effects of Epclusa during pregnancy are not known. If you are pregnant, think you may be pregnant or are planning to have a baby, ask your doctor for advice before taking this medicine.

Epclusa is sometimes used together with ribavirin. Ribavirin can harm your unborn baby. It is therefore very important that you (or your partner) do not become pregnant during this treatment or for a period of time after completing treatment. You must read the “Pregnancy” section in the ribavirin package leaflet very carefully. Ask your doctor for effective contraception method suitable for you and your partner.

Do not breast-feed during treatment with Epclusa. It is not known whether sofosbuvir or velpatasvir, the two active substances of Epclusa, pass into human breast milk.

Epclusa should not affect your ability to drive or use any tools or machinery.

This medicine contains less than 1 mmol sodium (23 mg) per tablet, that is to say essentially ‘sodium-free’.

The recommended dose of Epclusa in adults is one 400 mg/100 mg tablet once a day for 12 weeks.

The recommended dose of Epclusa in patients aged 3 to less than 18 years is based on weight. Take Epclusa as advised by your doctor.

Swallow the tablet(s) whole with or without food. Do not chew, crush or split the tablet as it has a very bitter taste.

If you are taking an antacid (medicines used to relieve heartburn), take it at least 4 hours before or at least 4 hours after Epclusa.

If you are taking a proton pump inhibitor (medicines used to reduce acid production), take Epclusa with food 4 hours before using a proton pump inhibitor.

If you are sick (vomit) after taking Epclusa it may affect the amount of Epclusa in your blood. This may make Epclusa work less well.

• If you are sick (vomit) less than 3 hours after taking Epclusa, take another dose.
• If you are sick (vomit) more than 3 hours after taking Epclusa, you do not need to take another dose until your next scheduled dose.

If you accidentally take more than the recommended dose you should contact your doctor or nearest emergency department immediately for advice. Keep the tablet bottle with you so that you can easily describe what you have taken.

It is important not to miss a dose of this medicine.

If you do miss a dose, work out how long it is since you last took your Epclusa:

• If you notice within 18 hours of the time you usually take Epclusa, you must take the dose as soon as possible. Then take the next dose at your usual time.
• If it’s 18 hours or more after the time you usually take Epclusa, wait and take the next dose at your usual time. Do not take a double dose (two doses close together).

Do not stop taking this medicine unless your doctor tells you to. It is very important that you complete the full course of treatment to give the medicine the best chance to treat your hepatitis C virus infection.
