Zyban : Uses, Side Effects, Interactions & More
For people taking Zyban for depression:
A small number of children, adolescents and young adults (up to age 24) who took antidepressants (‘mood elevators’) such as Zyban during clinical studies became suicidal (thinking about harming or killing themselves or planning or try to do it). Children, adolescents, and young adults who take antidepressants to treat depression or other mental illnesses may be more likely to become suicidal than children, adolescents, and young adults who do not take antidepressants to treat these conditions. This risk must be considered and weighed against the potential benefit in treating depression when deciding whether a child or adolescent should take an antidepressant. Children under the age of 18 should not normally take Zyban, but in some cases, a doctor may decide that Zyban is the best medicine for treating a child’s condition.
Regardless of your age, before taking an antidepressant, you, your parents, or your caregiver should discuss the risks and benefits of treating your condition with an antidepressant or other treatments with your doctor. You should also talk about the risks and benefits of not treating your condition. You should know that having depression or another mental illness greatly increases your risk of being suicidal, especially at the beginning of your treatment or any time your dose is increased or decreased. This risk is higher if you or someone in your family has or has ever had bipolar disorder or mania or has thought or tried to commit suicide. Talk to your doctor about your condition, symptoms, and personal and family medical history. You and your doctor will decide what type of treatment is right for you.
You should know that your mental health can change unexpectedly when you take Zyban or other antidepressants, even if you are an adult over the age of 24 or if you do not have a mental illness and are taking Zyban to treat a different type of condition. You may be suicidal, especially at the beginning of your treatment and any time your dose is increased or decreased. You, your family, or your caregiver should call your doctor right away if you experience any of the following symptoms: new or worsening depression; thinking about, or planning or attempting to, hurt or commit suicide; extreme worry; agitation; panic attacks; Difficulty falling asleep or staying asleep; aggressive behavior; irritability; act without thinking; severe restlessness; and a frenzy of abnormal excitement. Make sure your family or caregiver knows what symptoms may be serious so they can call your doctor if you are unable to seek treatment on your own.
