Kalexate binds itself to potassium in your digestive tract. This helps prevent your body from absorbing too much potassium.

Kalexate is used to treat high levels of potassium in the blood, also called hyperkalemia.

Kalexate works differently from other medicines because it passes into your intestines without being absorbed into your blood stream.

Kalexate may also be used for purposes not listed in this medication guide.

• Generic Name: telaprevir
• Dosage Forms: n.a.
• Other Brand Names: Incivek

Telaprevir is used in combination with injectable peginterferon alfa (Pegasys®, Pegintron®) and ribavirin (Copegus®, Rebetol®) to treat chronic hepatitis C infection.

Telaprevir is an antiviral agent.

Telaprevir was available only with your doctor's prescription.
