The most common side effects of this medication are nausea, vomiting, and an upset stomach. It may also cause tingling or numbness in the hands and feet. Some patients will have abnormal liver function tests when they are on this drug. Thankfully, serious side effects are less common. However, they can occur. For example, individuals may notice vision changes or pain behind the eyes.

Other serious side effects include seizures, memory problems, and unusual behavior. Jaundice may occur as well, and some patients may experience bleeding gums or nosebleeds. Patients should call their doctor immediately if they have serious or persistent side effects. They should also inform them if they develop a fever that lasts more than seventy-two hours.
