Important information about Fetzima
What is the most important information I should know about depression, antidepressant medicines, other serious mental illnesses, suicidal thoughts or actions and serotonin syndrome?
Fetzima and other antidepressant medicines may cause serious side effects.
- Depression or other serious mental illnesses are the most important causes of suicidal thoughts or actions. Some people may have a particularly high risk of having suicidal thoughts or actions. These include people who have (or have a family history of) bipolar illness (also called manic-depressive illness).
- Antidepressant medicines may increase suicidal thoughts or actions in some children, teenagers, or young adults within the first few months of treatment. Fetzima is not approved for use in children. Talk to your child’s healthcare provider for more information.
- How can I watch for and try to prevent suicidal thoughts and actions?
- Pay close attention to any changes in mood, behavior, thoughts, or feelings, especially sudden changes. This is very important when an antidepressant medicine is started or when the dose is changed. Call your healthcare provider right away to report new or sudden changes in mood, behavior, thoughts, or feelings.
- Keep all follow-up visits with your healthcare provider as scheduled. Call your healthcare provider between visits as needed, especially if you have concerns about symptoms. Call your healthcare provider right away if you have any of the following symptoms or feelings, especially if they are new, worse, or worry you:
- attempts to commit suicide
- acting on dangerous impulses
- acting aggressive, being angry, or violent
- thoughts about suicide or dying
- new or worsening depression
- new or worsening anxiety
- feeling very agitated or restless
- panic attacks
- trouble sleeping
- new or worsening irritability
- an extreme increase in activity or talking (mania)
- other unusual changes in behavior or mood
- Serotonin syndrome: A rare, but potentially life-threatening condition called serotonin syndrome can happen when medicines such as Fetzima are taken with certain other medicines. Serotonin syndrome can cause serious changes in how your brain, muscles, heart and blood vessels, and digestive system work. Symptoms of serotonin syndrome may include:
- agitation, hallucinations, coma or other changes in mental status
- problems controlling your movements or muscle twitching
- fast heartbeat
- high or low blood pressure
- sweating or fever
- nausea or vomiting
- muscle stiffness or tightness
What else do I need to know about antidepressant medicines?
- Antidepressants are medicines used to treat depression and other illnesses. It is important to discuss all the risks of treating depression and also the risks of not treating it. You should discuss all treatment choices with your healthcare provider, not just antidepressant medications.
- Antidepressant medicines have other side effects. Talk to your healthcare provider about the possible side effects of the medicine prescribed for you or your family member.
- Antidepressant medicines can interact with other medicines. Know all of the medicines that you or your family member takes. Keep a list of all medicines (including prescription, over-the-counter, vitamins and herbal supplements) to show your healthcare provider. Do not start new medicines without first checking with your healthcare provider.
- Never stop an antidepressant medicine without first talking to your healthcare provider. Stopping an antidepressant medicine suddenly can cause other symptoms.
