Tyzeka Side Effects

If you are taking Tyzeka and develop numbness in your arms or legs, problems walking, or difficulty breathing, contact your healthcare provider right away. Serious problems can occur with this medication, so it is important to be aware of which reactions require immediate medical treatment. Fortunately, most side effects of Tyzeka, such as fatigue, headaches, and diarrhea, tend to be minor.

An Introduction to Tyzeka Side Effects

Just like any medicine, Tyzeka® (telbivudine) can cause side effects. However, not everyone who takes the drug will have problems. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or are treated easily by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Tyzeka. Your healthcare provider can discuss a more complete list with you.)
