It is very important that your doctor check your progress at regular visits to make sure this medicine is working properly. Blood tests may be needed to check for unwanted effects.
Using this medicine together with ribavirin while you are pregnant can harm your unborn baby. These medicines may also cause birth defects if the father is using it when his sexual partner becomes pregnant. If a pregnancy occurs while you are using these medicines, tell your doctor right away.
To make sure you are not pregnant, your doctor may ask you to have a pregnancy test before you start using this medicine. You must have a negative pregnancy test before you will be allowed to use this medicine with ribavirin. Two forms of birth control must be used during treatment and for 6 months after treatment ends. You should test for pregnancy every month while you are using this medicine, and for 6 months after your treatment ends.
Do not take Olysio® in combination with sofosbuvir together with amiodarone. Using these medicines together may slow your heartbeat (bradycardia). Symptoms include fainting, dizziness, lightheadedness, trouble breathing, chest pain, or tiredness or weakness.
Check with your doctor right away if you have pain or tenderness in the upper stomach, pale stools, dark urine, loss of appetite, nausea, vomiting, or yellow eyes or skin. These could be symptoms of a serious liver problem.
This medicine may cause rashes and skin reactions to sunlight, which can be severe and must be treated in the hospital. This usually occurs during the first 4 weeks of treatment with simeprevir, peginterferon alfa, and ribavirin combination. Stay out of the sun as much as possible. Use a sunscreen or sun-blocking lotion when you are outdoors. Wear protective clothing and hats. Avoid sunlamps and tanning beds.
Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal (eg, milk thistle, St. John's wort) or vitamin supplements.
