telaprevir oral Warnings

Patients receiving telaprevir combination therapy have rarely experienced very serious (possibly fatal) skin reactions. Seek immediate medical attention if you develop any of the following symptoms of a skin reaction: skin rash/blisters/peeling, itching, swelling of your face, sores, eye redness, or fever.

Skin rash commonly occurs in patients taking telaprevir. Your doctor will determine if you need treatment for your skin rash or if you need to stop taking telaprevir, or any of your other medications. Never stop taking your medications without talking to doctor or pharmacist first. If you have stopped taking telaprevir due to a rash, you must never take telaprevir again. Ask your doctor or pharmacist for more details.

telaprevir oral Uses

Telaprevir is an antiviral used in combination with peginterferon and ribavirin to treat chronic (long-lasting) hepatitis C, a viral infection of the liver. Telaprevir is a protease inhibitor. It works by reducing the amount of hepatitis C virus in your body, which may help your liver recover. Chronic hepatitis C infection can cause serious liver problems such as scarring (cirrhosis), or liver cancer.

This combination reduces the amount of hepatitis C virus in the body and helps the body's immune system fight the infection. It is not known if this treatment can prevent you from passing the virus to others. Do not share needles, and practice "safe sex" (including the use of latex condoms/dental dams) to lower the risk of passing the virus to others.

Do not use telaprevir alone to treat hepatitis C.

How to use telaprevir oral

Read the Medication Guide provided by your pharmacist before you start taking telaprevir and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth as directed by your doctor, usually twice daily (every 10 to 14 hours). Telaprevir must be taken with food so your body can absorb it properly, so eat a meal or snack that contains at least 20 grams of fat within 30 minutes of taking your dose. Ask your doctor or pharmacist about what kinds of food have the right amount of fat to improve the absorption of telaprevir.

The dosage is based on your medical condition, response to treatment, and other medications you may be taking.

Telaprevir works best when the amount of medicine in your body is kept at a constant level. Therefore, take this drug at evenly spaced intervals. To help you remember, take it at the same times each day.

Continue to take this medication until the full prescribed amount is finished. Do not change your dose, skip any doses, or stop this medication early without your doctor's approval.
