This medication should not be used if you have certain medical conditions. Before using this medicine, consult your doctor or pharmacist if you have or have had: seizures, eating disorders (e.g., bulimia, anorexia nervosa).
This medication should not be used if you are suddenly stopping regular use of sedatives (e.g., benzodiazepines such as lorazepam) or alcohol, which may increase your risk of seizures.
Before using this medication, tell your doctor or pharmacist your medical history, especially of: alcohol/drug dependence, brain tumor, diabetes, head injury, heart disease (e.g., congestive heart failure, recent heart attack), high blood pressure, kidney problems, liver problems (e.g., cirrhosis), mental/mood disorders (e.g., bipolar disorder, thoughts of suicide).
This drug may make you dizzy, drowsy, or cause blurred vision. Do not drive, use machinery, or do any activity that requires alertness or clear vision until you are sure you can perform such activities safely. Limit or avoid alcoholic beverages. Alcohol can increase your risk of dizziness or seizures.
Do not take this medicine with any other product that contains bupropion (e.g., antidepressants) since large doses of bupropion are more likely to cause seizures.
Kidney function declines as you grow older. This medication is removed by the kidneys. Therefore, elderly people may be more sensitive to this drug and to side effects.
This medication should be used only when clearly needed during pregnancy. Behavioral therapy and stop-smoking education is preferred for pregnant women who desire to stop smoking. Discuss the risks and benefits with your doctor. Infrequently, newborns whose mothers have used certain newer antidepressants during the last 3 months of pregnancy may develop symptoms including persistent feeding or breathing difficulties, jitteriness, seizures or constant crying. Promptly report any such symptoms to the doctor. However, do not stop taking this medication unless your doctor directs you to do so.
