It is very important that your doctor check your progress at regular visits.
If your symptoms do not improve within 2 to 3 weeks, or if they become worse, check with your doctor.
If cycloserine causes you to feel very depressed or to have thoughts of suicide, check with your doctor immediately. Your doctor will probably want to change your medicine.
This medicine may cause some people to become dizzy, drowsy, or less alert than they are normally. Make sure you know how you react to this medicine before you drive, use machines, or do anything else that could be dangerous if you are dizzy or are not alert. If these reactions are especially bothersome, check with your doctor.
Some of cycloserine's side effects (for example, convulsions [seizures]) may be more likely to occur if you drink alcoholic beverages regularly while you are taking this medicine. Therefore, you should not drink alcoholic beverages while you are taking this medicine.
