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

• If you are allergic to sofosbuvir or any of the other ingredients of this medicine (listed in section 6 of this leaflet).
• If you are currently taking any of the following medicines:
  • Rifampicin (antibiotic used to treat infections, including tuberculosis);

If any of these conditions apply to you, tell your doctor immediately.

Sovaldi is always taken with other medicines to treat hepatitis C (see section 1 above). Talk to your doctor or pharmacist before taking this medicine 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 Sovaldi is needed, you may require additional heart monitoring;
• have liver problems other than hepatitis C, e.g. if you are awaiting a liver transplantation;
• have a current or previous infection with the hepatitis B virus, since your doctor may want to monitor you more closely;
• have diabetes. You may need closer monitoring of your blood glucose levels and/or adjustment of your diabetes medication after starting Sovaldi. Some diabetic patients have experienced low sugar levels in the blood (hypoglycaemia) after starting treatment with medicines like Sovaldi.

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 Sovaldi. This is so your doctor can:

• Decide what other medicines you should take with Sovaldi and for how long;
• 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 Sovaldi 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 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 Sovaldi.

Talk to your doctor about taking Sovaldi if you are taking any of the following medicines:

• Oxcarbazepine (a medicine used to treat epilepsy and prevent seizures);
• Modafinil (a medicine to treat people with narcolepsy to help them stay awake).
• Rifapentine (a medicine used to treat infections, including tuberculosis);

This is because they may make Sovaldi work less well.

Tell your doctor if you take any of the following medicines:

• amiodarone, used to treat irregular heartbeats.

If you are not sure of what medicines can be taken with Sovaldi, talk to your doctor or pharmacist.
