Fluvoxamine
About Fluvoxamine
Fluvoxamine is a selective serotonin reuptake inhibitor (SSRI) used to treat obsessive-compulsive disorder (OCD). In some cases, it may also be prescribed for other mental health conditions, such as depression and certain anxiety disorders, based on your doctor's clinical judgement. It works by helping restore the balance of serotonin, a natural chemical in the brain that regulates mood, anxiety, and behaviour.
To get the most benefit, you should take Fluvoxamine consistently at the same time every day, either with or without food. Establishing a regular daily routine helps maintain steady levels of the medicine in your body. Making simple lifestyle adjustments, such as keeping a consistent sleep schedule and practising relaxation techniques, can also support your progress.
While taking Fluvoxamine, some people may experience mild side effects like nausea, sleepiness, or dry mouth. These symptoms often improve as your body adjusts to the medication. However, if you notice severe changes in mood, unusual bruising, or an irregular heartbeat, contact your doctor right away.
Before starting this medication, tell your doctor if you have a history of liver damage, bipolar disorder, or seizures. Do not take this if you are currently taking monoamine oxidase inhibitors (MAOIs) or certain other medications, as this can cause dangerous reactions.
This medicine can interact with alcohol, which may increase drowsiness. Smoking may lower the amount of Fluvoxamine in your body in some people, which could affect how well it works. Fluvoxamine also strongly affects the way your body processes certain medicines by inhibiting the CYP1A2 and CYP2C19 enzymes, which can increase the levels of medicines such as theophylline, clozapine, and some benzodiazepines. If you are pregnant, breastfeeding, an older adult, or younger than 25 years of age, talk to your doctor before starting treatment, as closer monitoring may be needed.
