Telbivudine can cause serious side effects, including:
Lactic Acidosis (build-up of an acid in the blood). Lactic acidosis can occur in people who take medicines like telbivudine (a nucleoside analogue). Lactic acidosis is a serious medical emergency that can lead to death. Lactic acidosis must be treated in the hospital. Women, and people who are obese, or who have taken nucleoside analogues like telbivudine for long periods of time may be at higher risk for lactic acidosis.
Lactic acidosis can be hard to identify early, because the symptoms could seem like symptoms of other health problems. Call your healthcare provider right away if you get any of the following symptoms which could be signs of lactic acidosis:
- You feel very weak or tired.
- You have unusual (not normal) muscle pain.
- You have trouble breathing.
- You have stomach pain with nausea and vomiting.
- You feel cold, especially in your arms and legs.
- You feel dizzy or light-headed.
- You have a fast or irregular heartbeat.
Liver problems. Serious liver problems have occurred in some people who take medicines like telbivudine. This includes liver enlargement (hepatomegaly) and fat in the liver (steatosis).
Call your healthcare provider right away if you get any of these signs of liver problems:
- Your skin or the white part of your eyes turns yellow (jaundice).
- Your urine turns dark.
- Your bowel movements (stools) turn light in color.
- You do not feel like eating food for several days or longer.
- You feel sick to your stomach (nausea).
- You have lower stomach pain.
Muscle problems (myopathy). Telbivudine can cause muscle problems, including unexplained muscle pain, muscle weakness or muscle tenderness. Serious muscle problems can occur, including muscle breakdown (rhabdomyolysis). Muscle breakdown can lead to kidney damage. Tell your healthcare provider right away if you have unexplained muscle aches, pain, tenderness, or weakness.
Nerve problems. People who take telbivudine alone or with any type of injectable interferon product can have nerve problems such as continuing numbness, tingling, burning sensations in the arms or legs (peripheral neuropathy), or problems walking. Call your healthcare provider right away if you have any of these symptoms.
- Do not take telbivudine when you are also taking Pegasys (pegylated interferon alfa-2a) since your chance of having nerve problems may be higher and the nerve problems may be more severe.
If you take telbivudine with any type of injectable interferon product, your chance of having nerve problems may be higher and the nerve problems may be more severe. Be sure to tell your healthcare provider or pharmacist if you are also being treated with any type of injectable interferon for chronic hepatitis B or C. Check with your healthcare provider if you are not sure whether you are taking an injectable interferon product.
