A small number of children, teenagers, and young adults (up to 24 years of age) who took antidepressants ('mood elevators') such as fluvoxamine during clinical studies became suicidal (thinking about harming or killing oneself or planning or trying to do so). Children, teenagers, and young adults who take antidepressants to treat depression or other mental illnesses may be more likely to become suicidal than children, teenagers, and young adults who do not take antidepressants to treat these conditions. However, experts are not sure about how great this risk is and how much it should be considered in deciding whether a child or teenager should take an antidepressant.
You should know that your mental health may change in unexpected ways when you take fluvoxamine or other antidepressants even if you are an adult over 24 years of age. You may become suicidal, especially at the beginning of your treatment and any time that 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 harming or killing yourself, or planning or trying to do so; extreme worry; agitation; panic attacks; difficulty falling asleep or staying asleep; aggressive behavior; irritability; acting without thinking; severe restlessness; and frenzied abnormal excitement. Be sure that your family or caregiver knows which symptoms may be serious so they can call the doctor if you are unable to seek treatment on your own.
Your healthcare provider will want to see you often while you are taking fluvoxamine, especially at the beginning of your treatment. Be sure to keep all appointments for office visits with your doctor.
The doctor or pharmacist will give you the manufacturer's patient information sheet (Medication Guide) when you begin treatment with fluvoxamine. Read the information carefully and ask your doctor or pharmacist if you have any questions. You also can obtain the Medication Guide from the FDA website: Web Site.
No matter your age, before you take an antidepressant, you, your parent, or your caregiver should talk to your doctor about the risks and benefits of treating your condition with an antidepressant or with other treatments. 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 the risk that you will become suicidal. This risk is higher if you or anyone in your family has or has ever had bipolar disorder (mood that changes from depressed to abnormally excited) or mania (frenzied, abnormally excited mood) or has thought about or attempted 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.
WHY is this medicine prescribed?
Fluvoxamine is used to treat obsessive-compulsive disorder (bothersome thoughts that won't go away and the need to perform certain actions over and over) and social anxiety disorder (extreme fear of interacting with others or performing in front of others that interferes with normal life). Fluvoxamine is in a class of medications called selective serotonin reuptake inhibitors (SSRIs). It works by increasing the amount of serotonin, a natural substance in the brain that helps maintain mental balance.
HOW should this medicine be used?
Fluvoxamine comes as a tablet and an extended-release capsule to take by mouth. The tablet usually is taken either once daily at bedtime or twice daily, once in the morning and once at bedtime. The extended-release capsule usually is taken, with or without food , once daily at bedtime. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take fluvoxamine exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Swallow the extended-release capsules whole; do not be crush or chew them.
Your doctor may start you on a low dose of fluvoxamine and gradually increase your dose, not more often than once every week, depending on how well the medication works for you and the side effects you experience.
It may take several weeks or longer for you to feel the full benefit of fluvoxamine. Continue to take fluvoxamine even if you feel well. Do not stop taking fluvoxamine without talking to your doctor. If you suddenly stop taking fluvoxamine, you may experience withdrawal symptoms such as irritability; agitation; dizziness; extreme worry; uneasiness; confusion; headache; tiredness; mood changes; difficulty falling asleep or staying asleep; or pain, burning, numbness, tingling or 'electric shock' sensations in the hands or feet. Your doctor probably will decrease your dose gradually.
Are there OTHER USES for this medicine?
Fluvoxamine is also used sometimes to treat depression. Talk with your doctor about the possible risks of using this medication for your condition.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
